Athenex, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Company and Nature of Business

Organization and Description of Business

Athenex, Inc. and subsidiaries (the “Company” or “Athenex”), originally under the name Kinex Pharmaceuticals LLC (“Kinex”), formed in November 2003, commenced operations on February 5, 2004, and operated as a limited liability company until it was incorporated in the State of Delaware under the name Kinex Pharmaceuticals, Inc. on December 31, 2012. The Company changed its name to Athenex, Inc. on August 26, 2015.

Athenex is a global biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies for the treatment of cancer. The Company’s mission is to improve the lives of cancer patients by creating more effective, safer and tolerable treatments. The Company’s current clinical pipeline is derived from Orascovery, Src Kinase Inhibition, T-cell receptor-engineered T-cells (TCR-T), and Arginine deprivation therapy research platforms. The Company has assembled a leadership team and has established global operations across the pharmaceutical value chain to execute its mission to become a global leader in bringing innovative cancer treatments to the market and improve health outcomes. The Company’s primary activities since inception have been conducting research and development activities through corporate collaborators, in-licensing and out-licensing pharmaceutical compounds and technology, conducting preclinical and clinical testing, recruiting personnel, identifying and evaluating additional drug candidates for potential in-licensing or acquisition, and raising capital to support development activities. The Company also conducts commercial sales of specialty products through its wholly-owned subsidiary, Athenex Pharmaceutical Division (“APD”), and 503B products through its wholly-owned subsidiary, Athenex Pharma Solutions (“APS”).

Follow-On Offering

In January 2018, the Company completed an underwritten public offering of 4,300,000 shares of its common stock. The Company granted the underwriters a 30-day option to purchase up to an additional 645,000 shares of common stock. In February 2018, the underwriters partially exercised their option, purchasing an additional 465,000 shares of common stock. All shares were offered by the Company at a price of $15.25 per share. The aggregate net proceeds were $68.1 million, net of underwriting discounts and commissions and offering expenses of $4.6 million.

Debt and Equity Offering

On July 3, 2018, the Company closed a privately placed debt and equity financing deal with Perceptive Advisors LLC and its affiliates (“Perceptive”) for gross proceeds of $100.0 million and received aggregate net proceeds of $97.1 million, net of fees and offering expenses. The Company entered into a 5-year senior secured loan for $50.0 million of this financing and issued 2,679,528 shares of its common stock at a purchase price of $18.66 per share for the remaining $50.0 million. The loan matures on the fifth anniversary from the closing date and bears interest at a floating per annum rate equal to London Interbank Offering Rates (“LIBOR”) (with a floor of 2.0%) plus 9.0%. The Company is required to make monthly interest-only payments with a bullet payment of the principal at maturity. The loan agreement contains specified financial maintenance covenants. In connection with the loan agreement, the Company granted Perceptive a warrant for the purchase of 425,000 shares of common stock at a purchase price of $18.66 per share. This was accounted for as a detachable warrant at its fair value and is recorded as an increase to additional paid-in-capital on the condensed consolidated statement of stockholders’ equity.

Private Placement

On May 7, 2019, the Company closed a private placement with Perceptive Life Sciences Master Fund, Ltd., Avoro Capital Advisors (formerly known as venBio Select Fund LLC), OrbiMed Partners Master Fund Limited and the Biotech Growth Trust PLC(combined known as OrbiMed), (collectively, the “Investors”), pursuant to which the Company sold an aggregate of 10 million shares of its common stock to the Investors at a purchase price of $10.0 per share for aggregate gross proceeds of $100.0 million, before deducting offering expenses. These shares were subsequently registered with the Securities and Exchange Commission on July 23, 2019.

Significant Risks and Uncertainties

The Company has incurred operating losses since its inception and, as a result, as of June 30, 2019 and December 31, 2018 had an accumulated deficit of $511.0 million and $443.7 million, respectively. As of June 30, 2019, the Company had $165.9 million of cash, cash equivalents, restricted cash, and short-term investments. Operations have been funded primarily through the sale of common stock

and, to a lesser extent, from convertible bond financing, a senior secured loan, revenue, and grant funding. The Company will require significant additional funds to conduct clinical trials and to fund its operations. There can be no assurances, however, that additional funding will be available on favorable terms, or at all. If adequate funds are not available, the Company may be required to delay, modify, or terminate its research and development programs or reduce its planned commercialization efforts. The Company believes that it will be able to obtain additional working capital through equity financings or other arrangements to fund operations, including additional public offerings; however, there can be no assurance that such additional financing, if available, can be obtained on terms acceptable to the Company. If the Company is unable to obtain such additional financing, the Company will need to reevaluate future operating plans and might delay, modify, or terminate its research and development programs or reduce its planned commercialization efforts. Accordingly, there is substantial doubt regarding the Company’s ability to continue as a going concern.

These condensed consolidated financial statements have been prepared on a going concern basis, which implies the Company will continue to realize its assets and discharge its liabilities in the normal course of the business. The Company’s recurring losses from operations and negative cash flows from operations have raised substantial doubt regarding its ability to continue as a going concern. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

The Company has a senior secured loan agreement which contains various covenants. A breach of any of these covenants could result in a default. If a default under this loan agreement is not cured or waived, the default could result in the acceleration of debt, which could require the Company to repurchase or repay the debt in full prior to the date it is otherwise due. If the Company defaults, the lender may seek repayment through the Company’s subsidiary guarantors or by executing on the security interest granted pursuant to the loan agreement.

The Company is subject to a number of risks similar to other biopharmaceutical companies, including, but not limited to, the lack of available capital, possible failure of preclinical testing or clinical trials, inability to obtain marketing approval of product candidates, competitors developing new technological innovations, unsuccessful commercialization strategy and launch plans for its proprietary drug candidates, market acceptance of the Company’s products, and protection of proprietary technology. If the Company does not successfully commercialize any of its product candidates, it will be unable to generate sufficient product revenue and might not, if ever, achieve profitability and positive cash flow.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information (Accounting Standards Codification (“ASC”) 270, Interim Reporting) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information necessary for a full presentation of financial position, results of operations, and cash flows in conformity with GAAP. In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. These condensed consolidated financial statements reflect the accounts and operations of the Company and those of its subsidiaries in which the Company has a controlling financial interest. Intercompany transactions and balances have been fully eliminated in consolidation.

Results of the operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results expected for the year ending December 31, 2019, or for any other future annual or interim period. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the Securities and Exchange Commission (“SEC”) on March 11, 2019.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the condensed consolidated financial statements and the reported amount of revenue and expenses during the reporting period. Such management estimates include those relating to assumptions used in clinical research accruals, chargebacks, allowance for doubtful accounts, inventory reserves, income taxes, the estimated useful life and recoverability of long-lived assets, and the valuation of stock-based awards. Actual results could differ from those estimates.

Leases

On January 1, 2019, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) on a modified retrospective basis and did not restate comparative periods as permitted under the transition guidance. The Company elected the package of practical expedients as permitted, which carries forward the Company’s assessments prior to the date of initial application with respect to lease classifications, initial direct costs as well as whether an existing contract contains a lease. The Company recognizes operating leases with terms greater than one year as right-of-use (ROU) assets and lease liabilities on its condensed consolidated balance sheet. The Company’s finance leases are included in property and equipment, net and long-term debt and finance lease obligations on the condensed consolidated balance sheet. A majority of the Company’s operating leases are for real estate properties used in operations located in the U.S. and Asia. The Company’s finance leases are for manufacturing equipment in the U.S.

ROU assets and lease liabilities are recognized based on the present value of the future lease payments over the contractual terms of the operating leases. The Company uses its incremental borrowing rate based on the information available at the date of initial adoption in determining the present value of the future lease payments. The Company uses the stated rate per each lease agreement in determining the finance lease liabilities. Lease terms may include options to extend or terminate when the Company is reasonably certain that the option will be exercised. The lease liabilities and ROU asset are amortized over the term of the lease with operating lease expenses being recognized on a straight-line basis over the lease terms.

The Company elected to apply the short-term lease measurement and recognition exemption in which ROU assets and lease liabilities are not recognized for short-term leases.

Concentration of Credit Risk, Other Risks and Uncertainties

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and short-term investments. The Company deposits its cash equivalents in interest-bearing money market accounts and invests in highly liquid U.S. treasury notes, commercial paper and corporate bonds. The Company deposits its cash with multiple financial institutions. Cash balances exceed federally insured limits. The primary focus of the Company’s investment strategy is to preserve capital and meet liquidity requirements. The Company’s investment policy addresses the level of credit exposure by limiting the concentration in any one corporate issuer and establishing a minimum allowable credit rating. The Company also has significant assets and liabilities held in its overseas manufacturing facility, and research and development facility in China, and therefore is subject to foreign currency fluctuation.

Recently Adopted Accounting Pronouncements

In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, "Leases (Topic 842)," which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new standard establishes a right-of-use model that requires a lessee to recognize a ROU asset representing the right to use the underlying asset over the lease term and lease liability on the balance sheet for all leases with a term longer than 12 months. Lease obligations are to be measured at the present value of lease payments and accounted for using the effective interest method. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. For finance leases, the leased asset is depreciated on a straight-line basis and recorded separately from the interest expense in the income statement resulting in higher expense in the earlier part of the lease term. For operating leases, the depreciation and interest expense components are combined, recognized evenly over the term of the lease, and presented as a reduction to operating income. The ASU requires that assets and liabilities be presented or disclosed separately and classified appropriately as current and noncurrent. The ASU further requires additional disclosure of certain qualitative and quantitative information related to lease agreements. In July 2018, the FASB issued new guidance that provided for a new optional transition method that allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to opening retained earnings. Under this approach, comparative periods are not restated.

The Company adopted the new lease standard on January 1, 2019 and used the effective date as the date of initial application. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company (1) to not reassess whether any expired or existing contracts are or contain leases, (2) to not reassess the lease classification for any expired or existing leases, and (3) to not reassess initial direct costs for any existing leases. The Company also elected the single component practical expedient, which requires the Company, by class of underlying asset, not to allocate the total consideration to the lease and nonlease components based on their relative stand-alone selling prices. This single component practical expedient requires the Company to account for the lease component and nonlease component(s) associated with that lease as a single component if (i) the timing and pattern of transfer of the lease component and the nonlease component(s) associated with it are the same and (ii) the lease component would be classified as an operating lease if it were accounted for separately. In preparation for

adoption of the standard, the Company implemented internal controls to enable the preparation of financial information. The standard had a material impact on its consolidated balance sheet, with no material impact on its consolidated statement of operations and comprehensive loss. On the adoption date, the Company recognized $9.8 million of operating lease ROU assets, $11.9 million of operating lease liabilities, and derecognized its existing deferred rent balance of $2.1 million.

In June 2018, the FASB issued ASU No. 2018-07, “Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting,” which expands the scope of Topic 718, “Compensation – Stock Compensation,” which only included share-based payments to employees, to include share-based payments issued to nonemployees for goods and services. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company will only need to remeasure liability-classified awards that have not yet been settled as of the date of adoption, and equity-classified awards for which a measurement date has not been established through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company adopted this standard on January 1, 2019 and the adoption of this ASU did not impact the Company’s condensed consolidated financial statements.

The remaining intangible assets were acquired in connection with the acquisitions of APS (formerly known as QuaDPharma), Polymed Therapeutics, Inc. (“Polymed”), and Comprehensive Drug Enterprises (“CDE”). Intangible assets are amortized using an economic consumption model over their useful lives. The APS customer list is being amortized on a straight-line basis over 7 years. The Polymed customer list and technology are amortized on a straight-line basis over 6 and 12 years, respectively. The CDE in-process research and development, (“IPR&D”), will not be amortized until the related projects are completed. IPR&D will be tested annually for impairment, unless conditions exist causing an earlier impairment test (e.g., abandonment of project). No impairment charges were recorded during the six months ended June 30, 2019. The weighted-average useful life for all intangible assets was 7.6 years as of June 30, 2019.

The Company recorded $0.5 million and $0.4 million of amortization expense for the three-month periods ended June 30, 2019 and 2018, respectively, and $0.9 million and $0.8 million of amortization expense for the six-month periods ended June 30, 2019 and 2018, respectively.

6. Fair Value Measurements

Financial instruments consist of cash and cash equivalents, restricted cash, short-term investments, an equity investment, accounts receivable, accounts payable, accrued liabilities, and debt. Short-term investments and the equity investment are stated at fair value. Cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities, and debt, are stated at their carrying value, which approximates fair value due to the short time to the expected receipt or payment date of such amounts.

ASC 820, Fair Value Measurements, establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under the ASC 820 are described as follows:

Level 1—Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.

Level 2—Inputs to the valuation methodology include:

•

Quoted prices for similar assets or liabilities in active markets;

•

Quoted prices for identical or similar assets or liabilities in inactive markets;

•

Inputs other than quoted prices that are observable for the asset or liability;

•

Inputs that are derived principally from or corroborated by observable market data by correlation or other means; and

•

If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3—Inputs to the valuation methodology are unobservable, supported by little or no market activity, and are significant to the fair value measurement.

Transfers between levels, if any, are recorded as of the beginning of the reporting period in which the transfer occurs. There were no transfers between Levels 1, 2 or 3 for any of the periods presented.

The following tables represent the fair value hierarchy for those assets and liabilities that the Company measures at fair value on a recurring basis (in thousands):

	Fair Value Measurements at June 30, 2019 Using:
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Available-for-sale investment		388		388		—		—
Total assets	$	63,050	$	413	$	62,637	$	—

The Company classifies its money market funds within Level 1 because it uses quoted market prices to determine their fair value. The Company classifies its commercial paper, corporate notes, and U.S. government bonds within Level 2 because it uses quoted prices for similar assets or liabilities in active markets and each has a specified term and all Level 2 inputs are observable for substantially the full term of each instrument.

The Company owns 68,000 shares of PharmaEssentia, a company publicly traded on the Taiwan OTC Exchange. As of June 30, 2019 and December 31, 2018, the Company’s investment in PharmaEssentia was valued at the reported closing price. This investment is classified as a Level 1 investment and is recorded as an available-for-sale investment within short-term investments on the Company’s condensed consolidated balance sheet.

7. Acquisitions

CIDAL

On June 27, 2019, the Company entered into a definitive asset purchase agreement with CIDAL Limited (“CIDAL”), which was formed under the laws of the British Virgin Islands, a contract research organization with headquarters in Guatemala and operations in various countries in Latin America, whereby the Company will acquire certain assets and assume certain liabilities in exchange for approximately 45,000 shares of the Company’s common stock, subject to certain adjustments at closing, assumed liabilities, and milestone payments of up to an aggregate of 67,796 shares of our common stock upon the achievement of certain developmental and regulatory milestones through the third quarter of 2021. The acquisition is expected to strengthen the Company’s clinical research and operations capabilities and support its clinical development worldwide. The Company expects to account for the asset purchase using the acquisition method of accounting and accordingly, the identifiable assets acquired, and liabilities assumed will be recorded based upon management’s estimates of current fair values as of the acquisition date. The purchase price allocation is expected to result in approximately $1.4 million of goodwill. The acquisition had not closed as of June 30, 2019 and is subject to customary closing conditions.

AXIS

On June 29, 2018, the Company entered into a Share Subscription Agreement (“SSA”) for Axis Therapeutics (“Axis”), a subsidiary of the Company jointly owned by the Company and Xiangxue Life Sciences Limited (“XLifeSc”). Under the SSA, the Company contributed $30.0 million cash for a 55% ownership interest in Axis and XLifeSc contributed a license for IPR&D of certain immunotherapy technology for a 45% ownership interest in Axis. Also, on June 29, 2018, through a license agreement entered into between XLifeSc and Axis, XLifeSc granted Axis an exclusive, sublicensable worldwide (excluding mainland China) right and license to use its proprietary TCR-engineered T Cell therapy to develop and commercialize products for oncology indications (“TCR-T License”). Upon effectiveness of the TCR-T License and satisfaction of certain conditions of the license agreement, the Company issued 267,952 shares of its common stock equal to $5.0 million to XLifeSc as an upfront payment by Axis. On September 14, 2018, the Company completed the $30.0 million cash injection to Axis and all the closing conditions under the SSA were fulfilled.

The Company has consolidated the financial statements of Axis into its condensed consolidated financial statements as of and for the six months ended June 30, 2019 and as of and for the year ended December 31, 2018 using the voting interest model. The nonmonetary exchange of 45% of the shares of Axis for the IPR&D from XLifeSc has been accounted for as an asset acquisition that does not constitute a business under ASC 805. Therefore, the acquisition of IPR&D was expensed as research and development expense at its fair value. The Company determined that the fair value of the equity issued to XLifeSc was $24.5 million, considering the $30.0 million contribution made by the Company for its 55% ownership interest and the arms-length nature of the transaction. Accordingly, the Company recorded an expense of $24.5 million within research and development expenses on its consolidated statements of operations and comprehensive loss for the year ended December 31, 2018.

8. Accrued Expenses

Accrued expenses consist of the following (in thousands):

The accrued construction costs relate to the building of the manufacturing facility in Dunkirk, NY. Of this amount, the Company expects $39.9 million to be reimbursed by New York State. This amount is recorded within prepaid expenses and other current assets on the Company’s condensed consolidated balance sheet as of June 30, 2019. $20.0 million of the deferred revenue relates to a milestone payment received in connection with an out-license agreement; see Note 15 – Revenue Recognition for additional details.

9. Income Taxes

The Company did not record a provision for federal income taxes for the six months ended June 30, 2019 because it expects to generate a loss for the year ending December 31, 2019 and the Company’s net deferred tax assets continue to be fully offset by a valuation allowance. Tax expense to date is the result of recording a valuation allowance against the deferred tax asset related to foreign tax benefits on losses in the People’s Republic of China (“PRC”).

10. Debt and Lease Obligations

Debt

The Company’s debt as of June 30, 2019 and December 31, 2018, consists of the following (in thousands):

During 2018, the Company issued a senior secured loan with a principal value of $50.0 million and a maturity date of June 30, 2023. The loan bears interest at a floating per annum rate equal to LIBOR (with a floor of 2.0%) plus 9.0%. The Company is required to make monthly interest-only payments with a bullet payment of the principal at maturity.

During the first quarter of 2019, the Company was issued an unsecured, subordinated bank loan to fund operations in China. This loan has a principal value of $0.7 million, a maturity date of December 11, 2019, and bears interest at a fixed rate of 5.7% annually.

During the second quarter of 2019, the Company entered into a credit agreement which amended the existing partnership agreement with Chongqing Maliu Riverside Development and Investment Co., LTD (“CQ”), for a Renminbi ¥50.0 million line of credit to be used for the construction of the new active pharmaceutical ingredient (“API”) plant in China. The Company is required to repay the principal amount with accrued interest within three years after the plant receives the U.S. Current Good Manufacturing Practices (“cGMP”) certification, with 20% of the total loan with accrued interest is due within the first twelve months following receiving the certification, 30% of the total loan with accrued interest due within twenty-four months, and the remaining balance with accrued interest due within thirty-six months. Interest accrues at the three-year loan interest rate by the People’s Bank of China for the same period on the date of the deposit of the full loan amount. As of June 30, 2019, the balance due to CQ was $2.9 million.

11. Related Party Transactions

During the six months ended June 30, 2019 and 2018, the Company entered into transactions with individuals and companies that have financial interests in the Company. Related party transactions included the following:

In 2015, CDE signed an agreement with Avalon BioMedical (Management) Limited and its subsidiaries (“Avalon”) under which Avalon would receive certain administrative services and would occupy space at CDE’s research location. Avalon would reimburse CDE for these administrative services as incurred and pay CDE a percentage of the total rent payment based on its staff headcount occupying the Hong Kong research and development facility (See Note 16—Commitments and Contingencies). Certain members of the Company’s board and management collectively have a controlling interest in Avalon. The Company does not hold any interest in Avalon and does not have any obligations to absorb losses or any rights to receive benefits from Avalon. As of June 30, 2019 and December 31, 2018, Avalon held 786,061 shares of the Company’s common stock, which represented approximately 1% of the Company’s total issued shares for both periods. Balances due from Avalon recorded on the condensed consolidated balance sheets were not significant.

In June 2018, the Company entered into two in-licensing agreements with Avalon wherein the Company obtained certain intellectual property from Avalon in an effort to develop and commercialize the underlying products. Under these agreements the Company is required to pay upfront fees and future milestone payments and sales-based royalties. During the six months ended June 30, 2019, the Company recorded $5.5 million of upfront fees, consisting of $3.5 million in cash and $2.0 million in equity, as research and development expense on its condensed consolidated statement of operations and comprehensive loss. During the three months ended June 30, 2019 and 2018, no fees were paid to Avalon in connection with the license agreements.

In June 2019, the Company entered into an agreement whereby Avalon will hold a 90% ownership interest and the Company will hold a 10% ownership interest of the newly formed entity under the name Nuwagen Limited (“Nuwagen”), incorporated under the laws of Hong Kong. Nuwagen is principally engaged in the development and commercialization of herbal medicine products for metabolic, endocrine, and other related indications. The Company will contribute nonmonetary assets in exchange for the 10% ownership interest. The Company will not consolidate Nuwagen under the voting model but will record its interest as an investment under the cost method. As of June 30, 2019, the Company had not yet recorded the investment since the deal has not completed the closing process.

The Company earns consulting and licensing revenue from PharmaEssentia, an entity in which the Company has an investment classified as available-for-sale (see Note 6—Fair Value Measurements). Revenue and cost-sharing funds received from PharmaEssentia amounted to $0.3 million and $0.1 million for the three months ended June 30, 2019 and 2018, respectively.

The Company receives certain clinical development services from ZenRx Limited and its subsidiaries (“ZenRx”), a company for which one of the Company’s executive officers serves on the board of directors. In connection with such services, the Company made payments to ZenRx of $0.3 million and $0.1 million for the three months ended June 30, 2019 and 2018, respectively. In April 2013, the Company entered into a license agreement with ZenRx pursuant to which the Company granted an exclusive, sublicensable license to use certain of the Company’s intellectual property to develop and commercialize oral irinotecan and encequidar, and oral paclitaxel and encequidar in Australia and New Zealand, and a non-exclusive license to manufacture a certain compound, but only for use in oral irinotecan and encequidar and oral paclitaxel and encequidar. ZenRx is responsible for all development, manufacturing and commercialization, and the related costs and expenses, of any product candidates resulting from the agreement. No revenue was earned from this license agreement in the periods presented in these consolidated financial statements.

d.	Certain family members of executives perform consulting services to the Company. Such services were not significant to the condensed consolidated financial statements.

12. Stock-Based Compensation

Common Stock Option Plans

The Company has four equity compensation plans, adopted in 2017, 2013, 2007 and 2004 (the “Plans”) which authorize the grant of up to 16,000,000 shares of common stock to employees, directors, and consultants. On May 23, 2019, the board of directors approved the amendment and restatement of the 2017 Omnibus Incentive Plan, which increases the number of shares available for issuance under the 2017 plan by up to 500,000 shares, subject to the approval of the Company’s stockholders at the Company’s 2020 annual meeting of stockholders. Additionally, on June 14, 2017, the Company adopted its 2017 Employee Stock Purchase Plan (the “ESPP”), which authorizes the issuance of up to 1,000,000 shares of common stock for future issuances to eligible employees.

Stock Options

The total fair value of stock options vested and recorded as compensation expense during the three months ended June 30, 2019 and 2018, and six months ended June 30, 2019 and 2018 was $2.1 million, $3.1 million, $3.8 million, and $5.2 million, respectively. As of June 30, 2019, $12.9 million of unrecognized cost related to non-vested stock options was expected to be recognized over a weighted-average period of approximately 1.6 years. The total intrinsic value of options exercised was approximately $1.0 million and $3.7 million for the six months ended June 30, 2019 and 2018, respectively.

The following table summarizes the status of the Company’s stock option activity granted under the Plans to employees, directors, and consultants (in thousands, except stock option amounts and exercise price):

Employee Stock Purchase Plan

The ESPP is available to eligible employees as defined in the plan document. Under the ESPP, shares of the Company’s common stock may be purchased at a discount (15%) of the lesser of the closing price of the Company’s common stock on the first trading or the last trading day of the offering period. The current offering period extends from December 1, 2018 to June 30, 2019. The Company expects to offer six-month offering periods after the current period. The 2017 Plans reserved 1,000,000 shares of common stock for issuance under the ESPP. Stock-based compensation related to the ESPP amounted to $0.1 million and less than $0.1 for the three months ended June 30, 2019 and 2018, respectively, and $0.2 million and less than $0.1 million for the six months ended June 30, 2019 and 2018, respectively.

13. Net Loss per Share Attributable to Athenex, Inc. Common Stockholders

Basic net loss per share is calculated by dividing net loss attributable to Athenex, Inc. common stockholders by the weighted-average number of common shares issued, outstanding, and vested during the period. Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common stock and common stock equivalents for the period using the treasury-stock method. For the purposes of this calculation, warrants to purchase common stock and stock options are considered common stock equivalents but are only included in the calculation of diluted net loss per share when their effect is dilutive.

The following outstanding shares of common stock equivalents were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive:

15. Revenue Recognition

The Company records revenue in accordance with ASC, Topic 606 “Revenue from Contracts with Customers.” Under Topic 606, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which it expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of Topic 606, the entity performs the following five steps: (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract; (iii) determines the transaction price; (iv) allocates the transaction price to the performance obligations in the contract; and (v) recognizes revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Following is a description of principal activities – separated by reportable segments – from which the Company generates its revenue (See Note 14 – Business Segment, Geographic, and Concentration Risk Information).

Oncology Innovation Platform

License fees and consulting revenue

The Company out-licenses certain of its intellectual property (“IP”) and provides related consulting services to pharmaceutical companies in specific territories that allow the customer to use, develop, commercialize, or otherwise exploit the licensed IP. In accordance with Topic 606, the Company analyzes each of its out-licensing contracts with customers to identify each of the performance obligations within the contract. Each out-license contains multiple performance obligations. The Company has determined that each of its out-license agreements with customers are classified as functional licenses and are capable of being distinct, because the IP that is licensed carries standalone value and is not expected to be altered through the life of the agreement. Therefore, for each of its out-licensing agreements, the Company has determined that the execution of the license and delivery of the IP to the licensee is distinct from the other performance obligations identified in the arrangement within the context of the contract. The Company has considered the development services it is required to perform and determined that these services do not modify the license to the IP delivered. Also, the Company does not deem the license and the development services to be interdependent. As such, the Company records revenue at a point-in-time for its out-licensing if any of the transaction price is allocated to the obligation, including up-front licensing fee payments. The Company’s classification of each out-license as such requires significant judgment to be used by management. The Company considers the economic and regulatory characteristics of the licensed IP to determine if it has standalone value on the date of the licensing, which would make the licensing distinct and dictate that the Company recognizes any transaction price allocated to the license performance obligation at a point-in-time. Revenue recognized at a point-in-time for the execution of a distinct licensing of IP amounted to $0 for both the three months ended June 30, 2019 and 2018, and $0 and $25.0 million for the six months ended June 30, 2019 and 2018, respectively.

Other performance obligations included in the Company’s out-licensing agreements include reaching milestone development and regulatory events by performing research and development activities over the licensed IP. The Company reached a milestone event during the six months ended June 30, 2019. The Company considered the milestones to be variable consideration, as the entitlement to the consideration is contingent on the occurrence or nonoccurrence of future events. The Company has determined that milestone performance obligations are satisfied at a point-in-time. Certain out-licensing agreements include performance obligations to manufacture and provide drug product in the future for commercial sale when the licensed product is approved. For the commercial development milestones, the consideration in exchange for the license of the Company’s IP is contingent on the customer’s subsequent sales to another commercial customer. Consequently, the sales- or usage-based royalty exception would apply. Revenue will be recognized for the commercial development milestones as the underlying sales occur. To date, the Company has not satisfied any of these performance obligations as none of its drugs have been approved by the regulatory agencies in any of the licensed territories.

In addition to the multiple performance obligations, the Company’s out-licensing agreements include variable pricing. After the performance obligations are identified, the Company determines each portion of the transaction price, which generally includes upfront fees, milestone payments, and royalty payments. The Company begins by allocating the payments set forth in the agreement to the performance obligation to which the consideration is related. Then, the Company considers whether or not that transaction price is fixed, variable, or subject to return. If any portion of the transaction price is constrained by more than one performance obligation, the Company allocated that portion of the transaction price to the performance obligation that will be satisfied later and will not recognize revenue until it is fully satisfied and the constraint on the transaction price no longer exists. There are no other significant methods employed to allocate the transaction price to performance obligations in a contract. The Company exercises significant judgment when allocating the variable transaction prices to the proper performance obligations, considering if any of those payments are refundable or are contingent on any future events. The Company did not use any other significant judgments related to out-licensing revenue during the six months ended June 30, 2019 and 2018.

Grant revenue

The Company receives grant award funding to support its continuing research and development efforts. The Company considers these grants to be operating revenue as they support the Company’s primary operating activities. Revenue is recognized when the underlying performance obligation is satisfied, which is generally when all grant eligibility criteria are met at a point-in-time. Grant revenue is not significant to the condensed consolidated financial statements.

Global Supply Chain Platform

The Company’s Global Supply Chain Platform manufactures API for use internally in its research and development and clinical studies and for sale to pharmaceutical customers globally. The Company also generates revenue on this platform, by providing small to mid-scale cGMP manufacturing of clinical and commercial products for pharmaceutical and biotech companies and selling pharmaceutical products under 503B regulations set forth by the Food and Drug Administration (“FDA”).

Revenue earned by the Global Supply Platform is recognized when the Company has satisfied its performance obligation, which is the shipment or the delivery of drug products. The underlying contracts for these sales are generally purchase orders and the Company recognizes revenue at a point-in-time. Any remaining performance obligations related to product sales are the result of customer deposits and are reflected in the deferred revenue contract liability balance.

Commercial Platform

The Company’s Commercial Platform generates revenue by distributing specialty products through independent pharmaceutical wholesalers. The wholesalers then sell to an end-user, normally a hospital, alternative healthcare facility, or an independent pharmacy, at a lower price previously established by the end-user and the Company. Sales are initially recorded at the list price sold to the wholesaler. Because these prices will be reduced for the end-user, the Company records a contra asset in accounts receivable and a reduction to revenue at the time of the sale, using the difference between the list price and the estimated end-user contract price. Upon the sale by the wholesaler to the end-user, the wholesaler will chargeback the difference between the original list price and price at which the product was sold to the end-user and such chargeback is offset against the initial estimated contra asset. The significant estimates inherent in the initial chargeback provision relate to wholesale units pending chargeback and to the ultimate end-user contract selling price. The Company bases the estimate for these factors on product-specific sales and internal chargeback processing experience, as well as estimated wholesaler inventory stocking levels. The Company also offers cash discounts, which approximate 2.0% of the gross sales price, as an incentive for prompt customer payment, and, consistent with industry practice, the Company’s return policy permits customers to return products within a window of time before and after the expiration of product dating. The Company expects that its wholesale customers will make prompt payments to take advantage of the cash discounts and expects customers to use their right of return. Therefore, at the time of sale, product revenue and accounts receivable are reduced by the full amount of the discount offered and the return expected. As of June 30, 2019 and December 31, 2018, the Company’s total provision for chargebacks and other deductions totaled $11.1 million and $12.2 million, respectively, included as a reduction of accounts receivable. The Company’s total expense for chargebacks and other deductions was $20.1 million and $6.6 million for the three months ended June 30, 2019 and 2018, respectively, and $39.5 million and $12.9 million for the six months ended June 30, 2019 and 2018, respectively.

The Company also offers contractual allowances, generally rebates or administrative fees, to certain wholesale customers, group purchasing organizations (“GPOs”), and end-user customers, consistent with pharmaceutical industry practices. Settlement of rebates and fees may generally occur from one to five months from date of sale. The Company provides a provision for contractual allowances at the time of sale based on the historical relationship between sales and such allowances. Contractual allowances are reflected in the condensed consolidated financial statements as a reduction of revenue and accounts receivable or as accrued expenses.

The Company exercises significant judgment in its estimates of the variable transaction price at the time of the sale and recognizes revenue when the performance obligation is satisfied. Factors that determine the final net transaction price include chargebacks, fees for service, cash discounts, rebates, returns, warranties, and other factors. The Company estimates all of these variables based on historical data obtained from previous sales finalized with the end-user customer on a product-by-product basis. At the time of sale, revenue is recorded net of each of these deductions. Through the normal course of business, the wholesaler will sell the product to the end-user, determining the actual chargeback, return products, and take advantage of cash discounts, charge fees for services, and claim warranties on products. The final transaction price per product is compared to the initial estimated net sale price and reviewed for accuracy. The final prices and other factors are immediately included in the Company’s historical data from which it will estimate the transaction price for future sales. The underlying contracts for these sales are generally purchase orders including a single performance obligation, generally the shipment or delivery of products and the Company recognizes this revenue at a point-in-time.

As of June 30, 2019, $20.0 million of the deferred revenue balance relates to a license milestone payment received pursuant to an agreement held by the Oncology Innovation Platform and $0.2 million relates to customer deposits made by customers of the Global Supply Chain Platform and is included within accrued expenses on the condensed consolidated balance sheet. Upon the delivery and acceptance of certain clinical trial data by the customer, the Company will recognize revenue of $20.0 million and upon the delivery of certain drug product, the Company will recognize revenue of $0.2 million. The performance obligations to which this consideration was allocated was not satisfied as of June 30, 2019 and therefore, no revenue was recognized upon receipt of the milestone payment. The Company will recognize this amount as revenue when the underlying performance obligation is satisfied.

As of December 31, 2018, the $0.2 million contract liability related to customer deposits made by customers of the Global Supply Chain Platform. The Company satisfied its performance obligations allocated to these contract liabilities during the six months ended June 30, 2019.

Practical expedients used

During the adoption of ASC 606, the Company applied the practical expedient in paragraph 606-10-10-4, the Portfolio Approach. This allowed the Company to apply the new revenue standard to a portfolio of contracts with similar characteristics because it reasonably expected that the effects on the financial statements of applying the guidance to the portfolio would not differ materially from applying the guidance to the individual contracts within that portfolio. The Company used this to determine the cumulative catch-up required under the modified retrospective transaction method. The Company used the portfolio approach for product sales under the Global Supply Chain Platform and product sales under the Commercial Platform. The Company did not use this approach for its out-licensing contracts, because each of those contracts have unique economic characteristics.

The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations related to the license of intellectual property (“IP”). This practical expedient is applied because the out-licensing agreements include sales-based royalties in exchange for the license of IP accounted for in accordance with Topic 606 and there is significant uncertainty surrounding the future variable consideration that could be received.

Legal Proceedings

From time to time, the Company may be subject to claims and litigation arising in the ordinary course of business. These claims could include assertions that the Company’s products infringe existing patents or claims that the use of its products has caused personal injuries. The Company intends to vigorously defend any such litigation that may arise under all defenses that would be available. Regardless of the outcome, litigation can have an adverse impact on the Company because of prosecution, defense and settlement costs, unfavorable awards, diversion of management resources and other factors.

Vasopressin (Generic version of Vasostrict®)

On August 13, 2018, APS and APD, our wholly-owned subsidiaries, filed a complaint for declaratory judgment against Par Pharmaceuticals, Inc., Par Sterile Products, LLC and Endo Par Innovation Company, LLC (together, “Par”) in the United States District Court for the Western District of New York (the “Court”), seeking a declaratory judgment from the Court that our compounded vasopressin drug products in ready-to-use form do not infringe on patents that Par has with respect to its Vasostrict® product and that Par’s patents are invalid. On October 22, 2018, Par filed a motion to dismiss the complaint on the basis that the Court does not have subject matter jurisdiction. On July 9, 2019, the Court ordered dismissal of our complaint for lack of subject matter jurisdiction, finding that considering the totality of circumstances, we did not adequately allege that an actual controversy existed between the parties at the time the lawsuit was filed. We do not intend to appeal this dismissal. While Par has not alleged that our compounded vasopressin infringes any of its patents, Par could do so by commencing an infringement lawsuit against us. If such an infringement lawsuit were brought and a court ruled for Par, Athenex could be enjoined from further production of compounded vasopressin within in the United States and sale of compounded vasopressin in or from the United States and for payment of damages to Par for U.S. manufacture or sale of compounded vasopressin that has already taken place.

authorizing the compounding of vasopressin under Section 503B of the FDCA. We and FDA filed motions for judgment on the pleadings. On February 7, 2019, before resolving the above pending motions, the DC Court stayed the case until the earlier of: (i) March 15, 2019; (ii) FDA publishes in the Federal Register a final determination about whether to include vasopressin on the clinical need list; or (iii) Par notify the Parties and the Court of a substantial change in circumstances necessitating a decision on Plaintiffs' Motion for Preliminary Injunction. On March 4, 2019, FDA published in the Federal Register its final decision not to include vasopressin on the list of bulk drug substances for which there is a clinical need. On the same day, we (Athenex, Inc., APS, and APD) filed a complaint in the DC Court against FDA seeking to vacate its final decision. Par Sterile Products, LLC and Endo Par Innovation Company, LLC joined this case as intervenors. On March 11, 2019, the DC Court extended the stay of Par’s lawsuit against FDA until resolution of the motions for summary judgment in this newer related case.

In our case against FDA, FDA represented to the DC Court that “until the Court issues a decision on the merits of this action, FDA will not initiate enforcement action against Athenex based solely on Athenex’s use of the bulk drug substance vasopressin to compound drugs and distribute those drugs” and the DC Court incorporated FDA’s representation into its published order. As such, Athenex produced and distributed compounded vasopressin during the period that the case was pending before the DC District Court and prior to its decision.

On April 30, 2019, the DC Court held a hearing on the parties’ cross motions for summary judgment. On August 1, 2019, the DC Court issued a ruling upholding FDA’s vasopressin decision and dismissing Athenex’s complaint. Athenex has 60 days to file a notice of appeal with the U.S. Court of Appeals for the District of Columbia Circuit and has sought a stay of the DC Court’s order pending appeal. Athenex has ceased producing and distributing vasopressin and will continue to do so unless permitted by the Court and FDA.

Overview and Recent Developments

We are a global biopharmaceutical company dedicated to becoming a leader in the discovery, development, and commercialization of next generation drugs for the treatment of cancer. We are organized around three platforms, including an Oncology Innovation Platform, a Commercial Platform and a Global Supply Chain Platform. Our current clinical pipeline in the Oncology Innovation Platform is derived from four different platform technologies: (1) Orascovery, based on a non-absorbed P-glycoprotein inhibitor, (2) Src kinase inhibition, (3) T-cell Receptor-engineered T-cells (“TCR-T”), and (4) arginine deprivation therapy. We have assembled a strong and experienced leadership team and have established global operations across the pharmaceutical value chain to execute our mission to become a global leader in bringing innovative cancer treatments to the market and improve health outcomes. Below we describe our current plans to advance the technology in our Oncology Innovation Platform.

Lead Orascovery platform drug candidate: Oral paclitaxel and encequidar

In March 2019, we presented a poster highlighting the preclinical data of oral paclitaxel and encequidar in angiosarcoma, at the American Association of Cancer Research Annual Meeting.

In May 2019, we announced preliminary data showing promising early clinical responses in the first part of a two-part study of oral paclitaxel and encequidar monotherapy in patients with unresectable cutaneous angiosarcoma.

If we receive approval from the U.S. Food and Drug Administration (“FDA”), our strategy is to develop and commercialize oral paclitaxel and encequidar in the U.S. through our Commercial Platform. We also plan to evaluate marketing options outside of the U.S., including using our internal resources, partnering with others, or out-licensing the product. If our Phase 3 study in metastatic breast cancer is successful, we intend to establish oral paclitaxel and encequidar as the chemotherapy of choice for patients receiving chemotherapy for metastatic breast cancer and intend to file a New Drug Application (NDA) with the FDA to secure regulatory approval of oral paclitaxel and encequidar for metastatic breast cancer. If we receive regulatory approval from the FDA, we will then explore establishing oral paclitaxel and encequidar in other oncology indications where we believe taxanes will continue to be a foundational treatment and continue to explore combination therapies. During the remainder of 2019, we plan to focus on:

•

quantitative and qualitative market research, including on health outcomes and qualitative pricing, to understand our customers, patients, and the market;

•

examining our competitive landscape;

•

developing and completing brand strategy;

•

developing key opinion leader relationships;

•

attending priority medical conferences to increase awareness of the Company and oral paclitaxel and encequidar;

•

creating a market access strategy;

•

developing and executing a scientific publication plan;

•

developing our patient and patient advocacy strategy;

•

completing account, physician and patient segmentation in order to prioritize and target commercial efforts effectively;

•

developing our distribution and patient support plans;

•

completing our organizational design to determine the overall size of our go-to-market commercial team based on our market opportunity;

•

continuing to hire key commercial and medical affairs leadership roles;

•

completing a life cycle plan for oral paclitaxel and encequidar; and

•

preliminary marketing and launching forecasts.

We can provide no assurance that we will be successful in obtaining the FDA’s approval to commercialize oral paclitaxel and encequidar.

Lead Src Kinase Inhibition platform candidate: Tirbanibulin ointment, for Actinic Keratosis (AK)

Patient enrollment in two identical Phase 3 studies was completed in March 2018. The studies enrolled a total of 702 patients across 62 sites in the U.S. Tirbanibulin ointment 1% or vehicle (randomized 1:1) was self-administered to 25 cm2 of the face or scalp encompassing 4 to 8 typical AK lesions, once daily for 5 consecutive days.

In July 2018, we announced that both of these Phase 3 pivotal efficacy studies achieved their primary efficacy objective within the face or scalp treatment areas, with each study achieving statistical significance (p<0.0001) versus vehicle ointment for the primary endpoint of 100% clearance of AK lesions on the treatment area at Day 57.

In March 2019, we presented topline results from the two Phase 3 studies in a late breaker session at the 2019 American Academy of Dermatology (“AAD”) Annual Meeting. Results showed that 44% and 54% of patients in studies KX01-AK-003 and KX-01-AK-004, respectively, achieved 100% AK lesion clearance at Day 57 (see Table 1). The patient compliance rate in these two studies was greater than 99%. There was a statistically significant greater clearance rate in favor of the tirbanibulin ointment versus the vehicle in each of the pre-specified patient subgroups. Safety results showed that tirbanibulin ointment was well tolerated. Treatment-related adverse events occurred in 11-20% of patients in the two Phase 3 studies. These events were generally transient mild to moderate application site symptoms, such as pruritus or pain. There were no serious adverse events or early discontinuations that were considered related to the study drug. Local skin reactions were mostly mild to moderate and transient erythema, flaking/scaling and crusting. We believe that this product, if approved by regulatory authorities, could have a major impact in the medical treatment of AK.

As of July 22, 2019, there were no serious adverse events that were considered to be related to the study treatment.

Table 1: Efficacy Results of Tirbanibulin Ointment 1% in the Field Treatment of Actinic Keratosis, as presented at the 2019 AAD Annual Meeting in March 2019

Note:

a = p-value calculated based on Cochran-Mantel-Haenszel (CMH)

Lead TCR-T platform candidate: TAEST Therapy

In 2018, we commenced development of TCR-T immunotherapy technology, which harnesses and enhances the patient’s own immune cells to target and eliminate cancer. It is a cell-based therapy that takes advantage of the unique attributes of TCR mediated target recognition and provides a potent and selective TCR-T directed response against cancer cells.

In October 2018, we announced preliminary results of pilot studies in China in which patients received TCR affinity-enhancing specific T-cell (“TAEST”) therapy and showed encouraging positive clinical signals in patients with end-stage cancer. This study was conducted with our partner XLifeSc through our joint venture, Axis.

In March 2019, we announced that our partner, XLifeSc, received notice of allowance from the China National Medical Product Administration (“NMPA,” formerly known as the China Food and Drug Administration) of its Investigational New Drug (“IND”) to initiate registrational related clinical studies in China of TAEST therapy in patients with solid tumors that are HLA-A*02:01 positive and NY-ESO-1 positive. The cancer immunotherapy product, named TAEST16001 injection, is based on TAEST technology generated T-cells, with enhanced binding affinity, against the antigen NY-ESO-1 and is HLA-A*02:01 restricted.

Lead Arginine Deprivation Therapy platform candidate: Pegtomarginase

In June 2019, the FDA allowed the IND application for the clinical investigation of Pegtomarginase for the treatment of patients with advanced malignancies. The allowance is contingent on formal submission of agreed upon updates to the IND.

Also in June 2019, we presented preclinical study results of Pegtomarginase in a poster session at the 2019 American Society of Clinical Oncology Annual Meeting. The biologic agent demonstrated high enzymatic activity, predictable pharmacokinetic-pharmacodynamic profiles, and cytotoxicity in vitro. Mouse xenograft models showed good tumor growth inhibition activity at tolerable doses with only transient weight loss during therapy.

Additional business developments

In June 2019, we announced the strategic expansion of our presence in Europe and Latin America to grow our global clinical research and development capacity. We established offices in Manchester to support our ongoing clinical studies in the United Kingdom and to continue expanding our research and development capabilities in the region. We also entered into a definitive agreement to acquire certain assets of CIDAL Limited (“CIDAL”), subject to customary closing conditions. CIDAL is a contract research organization (“CRO”) with headquarters in Guatemala and operations in various countries in Latin America. CIDAL has provided CRO services and support for our Phase 3 study of oral paclitaxel and encequidar for metastatic breast cancer.

We have three operating segments: our Oncology Innovation Platform, Global Supply Chain Platform and Commercial Platform. Since inception, we have devoted a substantial amount of our resources to research and development of our lead product candidates under our Orascovery, Src Kinase Inhibition research platforms, and TCR-T Immunotherapy and Arginine Deprivation Therapy. We have incurred significant net losses since inception. Our net losses were $67.3 million and $44.2 million for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019 and December 31, 2018 we had an accumulated deficit of $511.0 million and $443.7 million, respectively. We expect to incur significant expenses and increasing operating losses for the foreseeable future. We anticipate that our expenses will increase substantially as we:

•

Continue to advance our lead programs, Orascovery and Src Kinase Inhibition research platforms, through clinical development;

•

Continue our current preclinical and clinical research program and development activities;

•

Advance the preclinical and clinical research program and development activities of our recently in-licensed technology platforms, TCR-T Immunotherapy and Arginine Deprivation Therapy;

•

Seek to identify additional research programs and product candidates;

•

Continue to invest in acquiring or in-licensing other drugs and technologies;

•

Continue to invest in our manufacturing facilities;

•

Continue to invest in further developing our Commercial Platform ahead of our intended proprietary drug launch;

•

Hire additional research, development and business personnel;

•

Maintain, expand and protect our intellectual property portfolio; and

•

Incur additional costs associated with operating as a public company.

On May 7, 2019, we completed a private placement equity offering of 10 million shares of common stock. All shares were offered by us at a price of $10.00 per share to three institutional investors, namely Perceptive Advisors, Avoro Capital Advisors (formerly known as venBio Select Advisor), and OrbiMed. The aggregate net proceeds received by us from the offering were $99.9 million, net of offering expenses of approximately $0.1 million. These shares were subsequently registered with the Securities and Exchange Commission on July 23, 2019.

Our revenue may be impacted by the current suspension of our operations at our API plant in Chongqing, China. We chose to suspend production based on concerns raised by the Department of Emergency Management of Chongqing related to the location of our plant. The voluntary temporary suspension began in May 2019 and we hope to reach a resolution of the suspension with the DEMC, but we can provide no assurances of when, if at all, production of API will resume at the plant. While we currently have secured additional API suppliers for our ongoing clinical studies, in the event the suspension continues for longer than expected, we may not be able to produce APIs from the Chongqing plant.

We have funded our operations to date primarily from the issuance and sale of our common stock through public offerings, private placements, and convertible bonds, debt and, to a lesser extent, through revenue generated from our Global Supply Chain Platform. As of June 30, 2019, we had cash, cash equivalents, restricted cash, and short-term investments of $165.9 million.

Key Components of Results of Operations

Revenue

We derive our consolidated revenue primarily from (i) the sales of 503B and API products by our Global Supply Chain Platform; (ii) the sales of generic injectable products by our Commercial Platform; (iii) licensing and collaboration projects conducted by our Oncology Innovation Platform, which generates revenue in the form of upfront payments, milestone payments and payments received for providing research and development services for our collaboration projects and for other third parties; and (iv) grant awards from government agencies and universities for our continuing research and development efforts.

We do not anticipate revenue being generated from sales of our product candidates under development in our Oncology Innovation Platform until we have obtained regulatory approval. We cannot assure you that we will succeed in achieving regulatory approval for our drug candidates as planned, or at all.

Cost of Sales

Along with sourcing from third-party manufacturers, we manufacture clinical products in our cGMP facility in New York and APIs at our cGMP facility in China through our Global Supply Chain Platform. Cost of sales primarily includes the cost of finished products, raw materials, labor costs, manufacturing overhead expenses and reserves for expected scrap, as well as transportation costs. Cost of sales also includes depreciation expense for production equipment, changes to our excess and obsolete inventory reserves, and certain direct costs such as shipping costs, net of costs charged to customers.

Research and Development Expenses

Research and development expenses consist of the costs associated with in-licensing of product candidates, milestone payments, conducting preclinical studies and clinical trials, activities related to regulatory filings and other research and development activities. Our current research and development activities mainly relate to the clinical development of our Oncology Innovation Platform:

Orascovery platform—Comprised of our in-licensed and novel P-gp inhibitor, encequidar(formerly known as HM30181A), that is combined with various chemotherapeutic agents and enables the agents to be absorbed into the blood when given orally:

•

Oral paclitaxel and encequidar, combining encequidar with an oral dosage form of paclitaxel;

•

Oral irinotecan and encequidar, combining encequidar with an oral dosage form of irinotecan;

•

Oral docetaxel and encequidar, combining encequidar with an oral dosage form of docetaxel;

•

Oral topotecan and encequidar, combining encequidar with an oral dosage form of topotecan; and

•

Oral eribulin and encequidar, combining encequidar with an oral dosage form of eribulin.

The World Health Organization has recommended “encequidar” as the International Nonproprietary Name (INN) for HM30181A

Src Kinase Inhibition platform—Targets the tyrosine kinase protein in regulating cell growth that leads to blockade of metastasis:

•

Tirbanibulin (also known as KX2-391 or KX-01) ointment, Src kinase inhibitor topically administered to treat skin cancers and pre-cancers;

•

Tirbanibulin oral, Src kinase inhibitor orally administered to treat certain solid and liquid tumors; and

•

KX2-361 (also known as KX-02), Src kinase inhibitor orally administered to treat brain cancer, such as glioblastoma multiforme (GBM).

The World Health Organization has recommended “tirbanibulin” as the INN for KX2-391.

TCR-T Immunotherapy and Arginine Deprivation Therapy platform—licensed in July 2018, and are still in early stage R&D development phase:

•

The TCR-T immunotherapy technology harnesses and enhances the patient’s own immune cells to target and eliminate cancer. It is a cell-based therapy that takes advantage of unique attributes of TCR mediated target recognition and provides a potent and selective TCR-T directed response against cancer cells.

•

The Arginine Deprivation Therapy product, based on pegylated genetically engineered human arginase, targets cancer growth and survival by interrupting the supply of an essential amino acid, arginine, to a proportion of cancers with disrupted urea cycle.

We expense research and development costs as incurred. We record costs for certain development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment or clinical site activations. We do not allocate employee-related costs, depreciation, rental and other indirect costs to specific research and development programs because these costs are deployed across multiple product programs under research and development.

We cannot determine with certainty the duration, costs and timing of the current or future preclinical or clinical studies of our drug candidates. The duration, costs, and timing of clinical studies and development of our drug candidates will depend on a variety of factors, including:

•

The scope, rate of progress, and costs of our ongoing, as well as any additional, clinical studies and other research and development activities;

•

Future clinical study results;

•

Uncertainties in clinical study enrollment rates;

•

Significant and changing government regulation; and

•

The timing and receipt of any regulatory approvals.

A change in the outcome of any of these variables with respect to the development of a drug candidate could mean a significant change in the costs and timing associated with the development of that drug candidate.

Research and development activities are central to our business model. We expect our research and development expenses to continue to increase for the foreseeable future as we continue to support the clinical trials of oral paclitaxel and encequidar, oral irinotecan and encequidar, oral docetaxel and encequidar, oral topotecan and encequidar, oral eribulin and encequidar, tirbanibulin ointment, tirbanibulin oral and KX2-361, as well as initiate and prepare for additional clinical and preclinical studies, including TCR-T and Arginine deprivation program activities. We also expect spending to increase in the research and development for API, 503B and specialty products. There are numerous factors associated with the successful commercialization of any of our drug candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. Additionally, future commercial and regulatory factors beyond our control will likely impact our clinical development programs and plans.

Selling, General and Administrative Expenses

Selling, general and administrative, (“SG&A”), expenses primarily consist of compensation, including salary, employee benefits and stock-based compensation expenses for sales and marketing personnel, and for administrative personnel that support our general operations such as executive management, legal counsel, financial accounting, information technology, and human resources personnel. SG&A expenses also include professional fees for legal, patent, consulting, auditing and tax services, as well as other direct and allocated expenses for rent and maintenance of facilities, development of the facility in Dunkirk, NY, insurance and other supplies used in the selling, marketing, general and administrative activities. SG&A expenses also include costs associated with our commercialization efforts for our proprietary drugs, such as market research, brand strategy and development work on market access, scientific publication, product distribution and patient support. Our expenses related to operating as a public company may increase when we are no longer able to rely on the “emerging growth company” exemption to certain disclosure and attestation requirements pursuant to the Jumpstart our Business Startups Act of 2012 (“JOBS Act”).

Revenue

Revenue from product sales increased significantly to $22.0 million, for the three months ended June 30, 2019, from $11.5 million for the three months ended June 30, 2018, an increase of $10.6 million or 92%. This increase was primarily attributable to an increase in 503B revenue of $6.0 million, an increase in the specialty product revenue of $4.6 million, and an increase in API sales of $0.6 million. These increases were offset by a decrease in medical device sales of $0.4 million and other revenue of $0.2 million.

Cost of Sales

Cost of sales for the three months ended June 30, 2019 totaled $16.9 million, an increase of $7.5 million, or 79%, as compared to $9.4 million for the three months ended June 30, 2018. This was primarily due to the increase of $5.8 million in cost of sales resulting from the sale of specialty products and $1.7 million from 503B and API products.

Research and Development Expenses

Research and development (“R&D”) expenses for the three months ended June 30, 2019 totaled $18.5 million, a decrease of $8.1 million, or 30%, as compared to $26.6 million for the three months ended June 30, 2018. This was primarily due to a decrease in licensing fees, clinical operations, and product development and included the following:

•

$5.6 million decrease as a result of milestone payments for drug in-licensing fees which occurred in 2018;

•

$2.1 million decrease of product development related to the scale up of 503B operations and the launch of specialty products in 2018; and

•

$1.9 million decrease of clinical costs related to the supply of encequidar and tirbanibulin ointment for clinical studies. In addition, patient costs on the two Phase 3 tirbanibulin studies decreased as both Phase 3 studies wind down.

The decrease in these R&D expenses was offset by an increase of $1.1 million of preclinical development costs related to the Arginase and TCR-T platforms, and a $0.4 million increase of R&D related compensation.

Selling, General, and Administrative Expenses

SG&A expenses for the three months ended June 30, 2019 totaled $17.2 million, an increase of $4.4 million, or 34%, as compared to $12.8 million for the three months ended June 30, 2018. This was primarily due to an increase of $3.7 million related to the costs of preparing to commercialize our proprietary drugs, if approved, and, an increase of $1.3 million of general administrative expenses including legal fees and other professional service fees, offset by a decrease of $0.6 million in administrative related compensation expense.

Interest (Expense) Income

Interest expense for the three months ended June 30, 2019 totaled $1.3 million, a change of $1.7 million as compared to $0.4 million interest income for the three months ended June 30, 2018. The interest expense in the current period was incurred from our long-term debt entered into during the third quarter of 2018.

Revenue

Our product sales increased significantly to $47.2 million for the six months ended June 30, 2019, from $24.1 million for the six months ended June 30, 2018. However, total revenue for the six months ended June 30, 2019 decreased by $1.9 million, or 4%, as compared to $49.4 million for the six months ended June 30, 2018. The decrease was primarily due to $25.0 million related to license milestone revenue earned in the first quarter of 2018, and $1.1 million decrease in medical device product sales and contract manufacturing revenue, offset by a $24.3 million increase in product sales, of which $10.9 million from the sales of 503B, $10.5 million from sales of specialty product and $2.8 million from API.

Cost of Sales

Cost of sales for the six months ended June 30, 2019 totaled $36.8 million, an increase of $16.1 million, or 77%, as compared to $20.8 million for the three months ended June 30, 2018. This was primarily due to the increase of $12.0 million in cost of sales from the sale of specialty products and $4.1 million in cost of sales from 503B and API products.

Research and development

Research and development (“R&D”) expenses for the six months ended June 30, 2019 totaled $43.0 million, a decrease of $4.9 million, or 10%, as compared to $47.9 million for the six months ended June 30, 2018. This was primarily due to a decrease in licensing fees, clinical operations, and product development and included the following:

•

$4.9 million decrease of clinical development costs related to encequidar and tirbanibulin ointment; and

•

$4.5 million decrease as a result of milestone payments for drug in-licensing fees and decrease of product development related to the scale up of 503B operations and the launch of specialty products in 2018.

The decrease in these R&D expenses was offset by an increase of $2.8 million of preclinical development costs related to the Arginase and TCR-T platforms, and a $1.7 million increase of R&D related compensation.

Selling, General, and Administrative Expenses

SG&A expenses for the six months ended June 30, 2019 totaled $32.4 million, an increase of $6.5 million, or 25%, as compared to $25.9 million for the six months ended June 30, 2018. This was primarily due to an increase of $6.2 million related to the costs of preparing to commercialize our proprietary drugs, if approved, and an increase of $1.3 million of general administrative expenses including legal fees and other professional service fees, offset by a decrease of $1.3 million in administrative related compensation expense.

Interest (Expense) Income

Interest expense for the six months ended June 30, 2019 totaled $2.8 million, a change of $3.3 million as compared to $0.6 million interest income for the six months ended June 30, 2018. The interest expense in the current period was incurred from our long-term debt entered into during the third quarter of 2018 while the interest income in the prior period was generated from our short-term investments.

Liquidity and Capital Resources

Capital Resources

Since our inception, we have incurred net losses and negative cash flows from our operations. Substantially all of our losses have resulted from funding our R&D programs, SG&A costs associated with our operations, and the development of our specialty drug operations in our Commercial Platform and 503B operations and the investment we are making in our Commercial Platform in anticipation of commercializing our proprietary drugs. We incurred net losses of $68.3 million and $44.3 million for the six months ended June 30, 2019 and 2018, respectively. As of June 30, 2019, we had an accumulated deficit of $511.0 million. Our primary use of cash is to fund R&D costs and to fund our Commercial Platform. Our operating activities used $37.8 million and $38.0 million of cash during the six months ended June 30, 2019 and 2018, respectively. We intend to continue to advance our various clinical programs which we expect will lead to increased cash outflow of R&D costs and increase our investments in commercialization activities for our proprietary drugs. In addition, we can provide no assurance that the funding requirements to diversify the product portfolio for specialty drug products in the Commercial Platform and 503B operations will decline in the future. Our principal sources of liquidity as of June 30, 2019 are cash and cash equivalents, restricted cash, and short-term investments totaling of $165.9 million.

In July 2018, we closed a privately placed debt and equity financing deal with Perceptive for gross proceeds of $100.0 million and received aggregate net proceeds of $97.1 million, net of fees and offering expenses. We entered into a 5-year senior secured loan for $50.0 million of this financing and issued 2,679,528 shares of its common stock at a purchase price of $18.66 per share for the remaining $50.0 million. The loan matures on the fifth anniversary from the closing date and bears interest at a floating per annum rate equal to LIBOR (with a floor of 2.0%) plus 9.0%. We are required to make monthly interest-only payments with a bullet payment of the principal at maturity. The loan agreement contains specified financial maintenance covenants. In connection with the loan agreement, we granted Perceptive a warrant for the purchase of 425,000 shares of common stock at a purchase price of $18.66 per share.

Based on the current operating plan, we expect that our cash, cash equivalents, and restricted cash as of June 30, 2019, together with cash to be generated from our operating activities, will enable us to fund our operations into the third quarter in 2020. We expect that our expenses will increase substantially as we continue to fund clinical and preclinical development of our research programs, pre-launch activities of our proprietary drugs and funding of our Commercial Platform and working capital and other general corporate purposes. We have based our estimates on assumptions that might prove to be wrong, and we might use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of our drug candidates, we are unable to accurately estimate the amounts of increased capital outlays and operating expenditures necessary to complete the development and commercialization of our drug candidates.

Our future capital requirements will depend on many factors, including:

•

Our ability to generate revenue and profits from our Commercial Platform or otherwise;

•

The costs, timing and outcome of regulatory reviews and approvals;

•

Progress of our drug candidates to progress through clinical development successfully;

•

The initiation, progress, timing, costs and results of nonclinical studies and clinical trials for our other programs and potential drug candidates;

•

The costs of preparing our Commercial Platform for the commercialization of our proprietary drugs;

•

The number and characteristics of the drug candidates we pursue;

•

The costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property related claims;

•

The extent to which we acquire or in-license other products and technologies; and

•

Our ability to maintain and establish collaboration arrangements on favorable terms, if at all.

We believe that the existing cash and cash equivalents, restricted cash, and short-term investments will not be sufficient to enable us to complete all necessary development or commercially launch our proprietary drug candidates. Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements, and government grants. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect rights of holders of common stock. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends and might require the issuance of warrants, which could potentially dilute the ownership interest of holders of common stock. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we might have to relinquish valuable rights to our technologies, future revenue streams or research programs or to grant licenses on terms that might not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we might be required to delay, limit, reduce, or terminate our product development or future commercialization efforts or grant rights to develop and market products or drug candidates that we would otherwise prefer to develop and market ourselves.

Cash Flows

The following table provides information regarding our cash flows for the six months ended June 30, 2019 and 2018:

	Six Months Ended June 30,
	2019			2018
	(in thousands)
Net cash used in operating activities	$	(37,773	)	$	(38,029	)
Net cash provided by (used in) investing activities		4,764			(56,553	)
Net cash provided by financing activities		104,698			69,099
Net effect of foreign exchange rate changes		715			267
Net increase (decrease) in cash, cash equivalents, and restricted cash	$	72,404		$	(25,216	)

Net Cash Used in Operating Activities

The use of cash in our operating activities resulted primarily from our net loss adjusted for non-cash charges and changes in components of working capital. The primary use of our cash in the periods presented was to fund our research and development, regulatory and other clinical trial costs, drug licensing costs, inventory purchases, pre-launch commercialization activities, and other expenditures related to sales, marketing and administration.

Net cash used in operating activities was $37.8 million for the six months ended June 30, 2019. This resulted primarily from our net loss of $68.3 million, adjusted for non-cash charges of $7.9 million, and by cash provided by our operating assets and liabilities of $22.7 million. Our operating assets decreased $3.4 million for accounts receivable mainly related to the decreased sales of API products in the current period, and $1.5 million for inventory of all drug products, while prepaid and accrued expenses increased by $25.3 million primarily related to Dunkirk construction. This manufacturing facility, which was originally planned to be 320,000 square feet, has expanded to meet the required needs of the facility to be approximately 409,000 square feet upon completion and within the terms of our agreement with FSMC. Our operating liabilities increased by $43.1 million mainly due to $24.3 million related to Dunkirk construction, and $20.0 million of deferred revenue related to a milestone payment received from Almirall S.A. (“Almirall”). We will recognize the milestone payment revenue upon confirmation from Almirall of their satisfactory review of certain data we submitted pursuant to the license agreement with Almirall. Our net non-cash charges during the six months ended June 30, 2019 primarily consisted of $5.1 million of stock-based compensation expense, and $1.8 million depreciation and amortization expense.

Net cash used in operating activities was $38.0 million for the six months ended June 30, 2018. This resulted principally from our net loss of $44.3 million, adjusted for non-cash charges of $9.9 million, and by cash used in our operating assets and liabilities of $3.6 million. Our operating assets decreased $3.3 million for accounts receivable related to API product sales as our API supplies to clinical studies increased and external sales decreased, while inventory increased by $5.2 million primarily related to the specialty drugs, and prepaid and other expenses increased by $4.2 million primarily related to Dunkirk construction which would be reimbursed by New York State. Our operating liabilities increased by $2.6 million, mainly due to the increases in deferred revenue related to the out-licensing fee payment. Our net non-cash charges during the six months ended June 30, 2018 primarily consisted of $6.2 million of stock-based compensation expense and $1.7 million depreciation and amortization expense.

Net Cash Provided by (Used in) Investing Activities

Net cash provided by investing activities was $4.8 million for the six months ended June 30, 2019, compared to $56.6 million net cash used in the six months ended June 30, 2018. This was primarily due to cash obtained by the maturities of short-term investments, including commercial paper, corporate notes, and U.S. government bonds.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $104.7 million for the six months ended June 30, 2019, which primarily consisted of net proceeds of $99.9 million from the issuance of our common stock from the private placement and $3.6 million from the issuance of debt to fund our new API plant in China, compared with $69.1 million for the six months ended June 30, 2018, which primarily consisted of net proceeds of $68.1 million from our follow-on public offering, net of underwriter discount and offering costs of $4.6 million and $1.6 million from the exercise of employee stock options.

Contractual Obligations

A summary of our contractual obligations as of June 30, 2019 is as follows:

	Payments Due by Period
	Within 1 Year		1 to 3 years		3 to 5 years		More than 5 years		Total Amounts Committed
	(in thousands)
Operating leases	$	3,236	$	5,127	$	4,265	$	2,953	$	15,581
Long-term debt		1,497		871		52,034		—		54,402
Finance lease obligations		214		342		—		—		556
Licensing fees		506		—		—		—		506
	$	5,453	$	6,340	$	56,299	$	2,953	$	71,045

The above table includes the Company’s operating leases and the amounts committed under those leases by each location: (1) The rental of our global headquarters in the Conventus Center for Collaborative Medicine in Buffalo, NY; (2) the rental of our research and development facility in the IC Development Centre in Hong Kong; (3) the rental of the Commercial Platform headquarters in Chicago, IL; (4) the rental of our clinical research and development facility in Cranford, NJ; (5) the rental of our clinical data management center in Taipei, Taiwan; (6) the rental of our Global Supply Chain distribution office in Houston, TX; (7) the rental of our Global Supply Chain API manufacturing facility in Chongqing, China; and (8) the rental of various other facilities and equipment located mainly in Buffalo, NY.

Off Balance Sheet Arrangements

We do not maintain any off-balance sheet partnerships, arrangements, or other relationships with unconsolidated entities or others, often referred to as structured finance or special purpose entities, which are established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Significant Judgments and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and related disclosures. These estimates form the basis for judgments we make about the carrying values of our assets and liabilities, which are not readily apparent from other sources. We base our estimates and judgments on historical experience and on various other assumptions that we believe are reasonable under the circumstances. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.

We believe that the assumptions and estimates associated with research and development expenses, chargebacks, stock-based compensation and inventory reserves have the most significant impact on our condensed consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.

With the exception of the change in accounting for leases under ASC 842 (see Note 10 – Debt and Lease Obligations), there have been no significant changes in our critical accounting policies and estimates as compared to the critical accounting policies and estimates disclosed in Management’s Discussion and Analysis of Financial Condition and Operations included in our Annual Report on Form 10-K for the year ended December 31, 2018.

Recent Accounting Pronouncements

In the normal course of business, we evaluate all new accounting pronouncements issued by the Financial Accounting Standards Board, the Securities and Exchange Commission (SEC), or other authoritative accounting bodies to determine the potential impact they may have on our condensed consolidated financial statements. See Note 2 of the Notes to Condensed Consolidated Financial Statements contained in Item 1 of this quarterly report on Form 10-Q for additional information about these recently issued accounting standards and their potential impact on our financial condition or results of operations.

JOBS Act

Under Section 107(b) of the Jumpstart Our Business Startups Act of 2012, (the “JOBS Act,”) an “emerging growth company” can delay the adoption of new or revised accounting standards until such time as those standards would apply to private companies. We have irrevocably elected not to avail ourselves of this exemption and, as a result, we will adopt new or revised accounting standards at the same time as other public companies that are not emerging growth companies. There are other exemptions and reduced reporting requirements provided by the JOBS Act that we are currently evaluating. For example, as an emerging growth company, we are exempt from Sections 14A (a) and (b) of the Exchange Act which would otherwise require us to (1) submit certain executive compensation matters to shareholder advisory votes, such as “say-on-pay,” “say-on-frequency” and “say-on-golden parachutes;” and (2) disclose certain executive compensation related matters. We also rely on an exemption from the rule requiring us to provide an auditor’s attestation report on our internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and the rule requiring us to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will continue to remain an “emerging growth company” until the earliest of the following: (1) the last day of the fiscal year following the fifth anniversary of the date of the completion of our initial public offering, or December 31, 2022, (2) the last day of the fiscal year in which our total annual gross revenue is equal to or more than $1 billion, (3) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years, or (4) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Foreign Currency Exchange Risk

A significant portion of our business is located outside the United States and, as a result, we generate revenue and incur expenses denominated in currencies other than the U.S. dollar, a majority of which is denominated in Chinese Renminbi, (“RMB”). In the six months ended June 30, 2019 and 2018, approximately 1% and 2%, respectively, of our sales, excluding intercompany sales, were denominated in foreign currencies. As a result, our revenue can be significantly impacted by fluctuations in foreign currency exchange rates. We expect that foreign currencies will represent a lower percentage of our sales in the future due to the anticipated growth of our U.S. business. Our international selling, marketing, and administrative costs related to these sales are largely denominated in the same foreign currencies, which somewhat mitigates our foreign currency exchange risk rate exposure.

Currency Convertibility Risk

A portion of our revenues and expenses, and a portion of our assets and liabilities are denominated in RMB. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China, (“PBOC”). However, the unification of exchange rates does not imply that RMB is readily convertible into U.S. dollars or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approvals of foreign currency payments by the PBOC or other institutions require submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.

Additionally, the value of the RMB is subject to changes in Chinese central government policies and international economic and political developments affecting supply and demand in the PRC foreign exchange trading system market.

Interest Rate Sensitivity

We had cash, cash equivalents and short-term investments of $165.9 million as of June 30, 2019. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. However, because of the short-term nature of the instruments in our portfolio, a sudden change in U.S. market interest rates is not expected to have a material impact on our condensed consolidated financial condition or results of operations. We do not believe that our cash or cash equivalents have significant risk of default or illiquidity.

As of June 30, 2019, we had $50 million of debt with Perceptive that bears interest at a floating per annum rate equal to 1-Month LIBOR (with a floor of 2%) plus 9%. If 1-Month LIBOR increased by 1%, we would be required to pay Perceptive an additional $0.5 million in interest annually. If 1-Month LIBOR decreased by 1%, we would be required to pay Perceptive $0.5 million less in interest annually. A material change in the short-term interest rate environment could have a material adverse effect on our condensed consolidated financial condition or results of operations.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Board Chairman (Principal Executive Officer) and our Chief Financial Officer (Principal Financial and Accounting Officer), evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2019. The term “disclosure controls and procedures,” as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well-designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2019, our Chief Executive Officer and Board Chairman (Principal Executive Officer) and our Chief Financial Officer (Principal Financial and Accounting Officer) concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended June 30, 2019 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

In addition, on August 13, 2018, APS and APD filed a motion to intervene and seek the dismissal of Par Sterile Products, LLC’s and Endo Par Innovation Company, LLC’s complaint against the FDA and certain governmental officials in the United States District Court for the District of Columbia (the “DC Court”). Our motion to intervene was granted. These two Par entities have sought declaratory and injunctive relief, including a preliminary injunction, against FDA and certain governmental officials that: (i) vasopressin be delisted from Category 1 of FDA’s list of bulk drug substances under evaluation pursuant to Section 503B of the FDCA, (ii) the expansion of FDA’s enforcement discretion to Category 1 substances, be enjoined; and (iii) that FDA be enjoined from authorizing the compounding of vasopressin under Section 503B of the FDCA. We and FDA filed motions for judgment on the pleadings. On February 7, 2019, before resolving the above pending motions, the DC Court stayed the case until the earlier of: (i) March 15, 2019; (ii) FDA publishes in the Federal Register a final determination about whether to include vasopressin on the clinical need list; or (iii) Par notify the Parties and the Court of a substantial change in circumstances necessitating a decision on Plaintiffs' Motion for Preliminary Injunction. On March 4, 2019, FDA published in the Federal Register its final decision not to include vasopressin on the list of bulk drug substances for which there is a clinical need. On the same day, we (Athenex, Inc., APS, and APD) filed a complaint in the DC Court against FDA seeking to vacate its final decision. Par Sterile Products, LLC and Endo Par Innovation Company, LLC joined this case as intervenors. On March 11, 2019, the DC Court extended the stay of Par’s lawsuit against FDA until resolution of the motions for summary judgment in this newer related case.

Item 1A. Risk Factors.

In addition to the other information contained in this Quarterly Report on Form 10-Q, you should carefully consider the factors discussed in Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018 (the “2018 Form 10-K”) in evaluating our business, financial position, future results, and prospects. The information presented below updates and supplements those risk factors for events, changes and developments since the filing of the 2018 Form 10-K and should be read in conjunction with the risks and other information contained in the 2018 Form 10-K. The risks described in our 2018 Form 10-K, as updated below, are not the only risks we face. Additional risks that we do not presently know or that we currently believe are not material could also materially adversely affect our business, financial position, future results and prospects.

Risks Related to Our Financial Position and Need for Additional Capital

We have incurred net losses every year since our inception and anticipate that we will continue to incur net losses for the foreseeable future.

Investment in pharmaceutical product development is highly speculative because it entails substantial upfront costs and expenses and significant risk that a drug candidate will fail to gain regulatory approval or become commercially viable. Since our formation, the company has relied on a combination of public and private securities offerings, public-private partnerships, the issuance of convertible notes and public grants to fund our operations. We have devoted most of our financial resources to research and development, including our non-clinical development activities and clinical trials. We have not generated substantial revenue from product sales to date, and we continue to incur significant development and other expenses related to our ongoing operations. As a result, we incurred losses in the six months ended June 30, 2019 and the years ended December 31, 2018, 2017 and 2016. For the six months ended June 30, 2019 and years ended December 31, 2018, 2017 and 2016, we reported net losses of $67.3 million, $117.4 million, $131.2 million and $87.7 million, respectively, and had an accumulated deficit of $511.0 million as of June 30, 2019. Substantially all of our operating losses have resulted from costs incurred in connection with our research and development programs and from selling, general and administrative expenses associated with our operations.

We expect to continue to incur losses for the foreseeable future, and we expect these losses to increase as we continue our development of, and seek regulatory approvals for, our drug candidates, and begin to commercialize approved drugs, if any. Typically, it takes many years to develop a new drug before it is available for treating patients. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses, our ability to generate revenue and the timing and amount of milestones and other required payments to third parties in connection with our potential future arrangements with third parties. If any of our drug candidates fail in clinical trials or do not gain regulatory approval, or if approved, fail to achieve market acceptance, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our prior losses and expected future losses have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

We expect our research and development expenses to continue to be significant in connection with our continued investment in our drug candidates and our ongoing and planned clinical trials for our drug candidates. Furthermore, if we obtain regulatory approval for our drug candidates, we expect to incur increased selling, general and administrative expenses. In addition, as a public company, we incur additional costs associated with operating as a public company. As a result, we expect to continue to incur significant and increasing operating losses and negative cash flows from operations for the foreseeable future. These losses have had and will continue to have a material adverse effect on our stockholders’ equity, financial position, cash flows and working capital.

Our ability to continue as a going concern will require us to obtain additional financing to fund our current operations, which may be unavailable on acceptable terms, or at all.

Our recurring losses from operations and our current operating plans raise substantial doubt about our ability to continue as a going concern. As a result, our independent registered public accounting firm included an explanatory paragraph in its report on our consolidated financial statements as of and for the year ended December 31, 2018 with respect to this uncertainty. Our ability to continue as a going concern will require us to obtain additional financing to fund our current operating plans. We believe that our existing cash and cash equivalents and short-term investments, together with cash to be generated from our operating activities, will be sufficient to fund our current operating plans through at least March 31, 2020. We have based these estimates, however, on assumptions that may prove to be wrong, and we could spend our available financial resources much faster than we currently expect and need to raise additional funds sooner than we anticipate. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, reduce or eliminate our research and drug development programs or commercialization efforts.

Our financial results are subject to volatility related to our revenue and expenses, and despite beginning to generate revenue from product sales, we have not yet been profitable and may never become profitable.

Our financial results are subject to volatility based on a number of factors, including the timing of milestone licensing fees that we receive or are required to pay, the change in product types produced by APD and whether those products are in high demand, our ability to predict the products in high demand in the market, competition in the market for generic drugs, and APS’s ability to resume selling our compounded vasopressin product. Our ability to generate revenue and become profitable depends upon our ability to successfully complete the development of, and obtain the necessary regulatory approvals for, our proprietary drug candidates, as we currently only have commercialized our API products, including paclitaxel and docetaxel, and specialty products, such as medical testing kits. Our product sales of API totaled $8.7 million, $18.0 million, $15.4 million and $15.3 million in the six months ended June 30, 2019 and the years ended December 31, 2018, 2017 and 2016, respectively. Our specialty products launched in March 2017 and sales totaled $26.3 million, $30.4 million, $17.2 million in the six months ended June 30, 2019 and the years ended December 31,

2018 and 2017, respectively. Our revenue may be impacted by the current suspension of our operations at our API plant in Chongqing, China. We chose to suspend production based on concerns raised by the DEMC related to the location of our plant. The voluntary temporary suspension began in May 2019 and we hope to reach a resolution of the suspension with the DEMC, but we can provide no assurances of when, if at all, production of API will resume at the plant. If the suspension is not resolved, we may not be able to generate revenue from the Chongqing API plant. Even if we are able to continue product sales of API, our revenue and gross margins are subject to fluctuation due to changes in product mix and the expenses we incur to continue our research and development and commercialization efforts.

We expect to continue to incur substantial and increasing losses through the projected development and commercialization of our drug candidates. None of our proprietary drug candidates have been approved for marketing in the U.S., China or any other jurisdiction, and they may never receive such approval. Our ability to achieve revenue and profitability is dependent on our ability to complete the development of our proprietary drug candidates, obtain necessary regulatory approvals, and have our proprietary drugs manufactured and successfully marketed.

Even if we receive regulatory approval of our proprietary drug candidates for commercial sale, we do not know when they will generate revenue, if at all. Our ability to generate revenue from product sales of our drug candidates depends on a number of factors, including our ability to:

	•	complete research regarding, and non-clinical and clinical development of, our proprietary drug candidates;
	•	formulate appropriate dosing protocols, drug preparations and capsule encapsulation methods;
	•	obtain regulatory approvals and marketing authorizations for drug candidates for which we complete clinical trials;
	•	develop a sustainable and scalable manufacturing processes, including establishing and maintaining commercially viable supply relationships with third parties and establishing our own manufacturing capabilities and infrastructure;
	•	compliantly launch and commercialize proprietary drug candidates for which we obtain regulatory approvals and marketing authorizations, either directly or with a collaborator or distributor;
	•	obtain market acceptance of our proprietary drug candidates and their routes of administration as viable treatment options;
	•	obtain optimal pricing for products in key global markets;
	•	obtain adequate coverage and reimbursement for our proprietary drug candidates from government (including U.S. federal healthcare programs) and private payors;
	•	identify, assess, acquire and/or develop new proprietary drug candidates;
	•	address any competing technological and market developments;
	•	negotiate and maintain favorable terms in any collaboration, licensing or other arrangements into which we may enter;
	•	maintain, protect and expand our portfolio of intellectual property rights, including patents, trade secrets and know-how;
	•	successfully commercialize our 503B outsourcing facility products and U.S. specialty pharmaceutical products;
	•	further develop our API business; and
	•	attract, hire and retain qualified personnel.

In addition, because of the numerous risks and uncertainties associated with drug development, we are unable to predict the timing or amount of increased expenses, or when, or if, we will be able to achieve or maintain profitability. In addition, our expenses could increase beyond expectations if we are required by the FDA, NMPA, or regulatory authorities in other jurisdictions to perform studies in addition to those that we currently anticipate. Even if our proprietary drug candidates are approved for commercial sale, we anticipate incurring significant costs associated with the commercial launch of these drugs.

If we fail to become profitable or are unable to sustain profitability on a continuing basis, we may be unable to continue our operations at planned levels and be forced to reduce our operations. Failure to become and remain profitable may adversely affect the market price of our common stock and our ability to raise capital and continue operations. A decline in the value of our company could also cause you to lose all or part of your investment.

We will need to obtain additional financing to fund our operations, and if we are unable to obtain such financing, we may be unable to complete the development and commercialization of our drug candidates.

We have financed our operations with a combination of public and private securities offerings, public-private partnerships, issuance of convertible notes and public grants. Our drug candidates will require the completion of regulatory review, significant sales and marketing efforts and substantial investment before they can provide us with any product sales revenue. Our operations have consumed substantial amounts of cash since inception. The net cash used for our operating activities was $37.8 million, $109.4 million, $81.5 million and $47.9 million for the six months ended June 30, 2019 and the years ended December 31, 2018, 2017 and 2016 respectively. We expect to continue to spend substantial amounts on advancing the clinical development of our proprietary drug candidates, launching and commercializing any proprietary drug candidates for which we receive regulatory approval, including building our own commercial organizations to address certain markets.

We will need to obtain additional financing to fund our future operations, including completing the development and commercialization of our proprietary drug candidates and to conduct additional clinical trials for the approval of our proprietary drug candidates if requested by regulatory bodies and to complete the development of any additional proprietary drug candidates we might discover. Moreover, our research and development expenses and other contractual commitments are substantial and are expected to increase in the future. In addition, we will require additional financial resources and personnel to begin operations at our public-private partnership facilities in Chongqing, China and Dunkirk, New York. To the extent the costs of constructing the Dunkirk facility exceed approximately $206 million, we will also be responsible for those costs.

Our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including, but not limited to:

	•	the progress, timing, scope and costs of our clinical trials, including the ability to timely enroll patients in our planned and potential future clinical trials;
	•	the outcome, timing and cost of regulatory approvals by the FDA, NMPA and regulatory authorities in jurisdictions where we seek such approvals, including the possibility that the FDA, NMPA or regulatory authorities may require that we perform more studies than those that we currently expect;
	•	our ability to secure adequate coverage and reimbursement for our proprietary drug candidates from government (including U.S. federal health care programs) and private payors;
	•	the number and characteristics of drug candidates that we may in-license and develop;
	•	our ability to successfully and compliantly launch and commercialize our drug candidates;
	•	the amount of sales and other revenues from drug candidates that we may commercialize, if any, including the selling prices for such potential products and the availability of adequate reimbursement by third-party payors;
	•	the amount of rebates or other price concessions we may owe under U.S. federal health care programs that cover and reimburse our proprietary drug candidates;
	•	the amount and timing of the milestone and royalty payments we receive from our collaborators under our licensing arrangements;
	•	the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;
	•	selling and marketing costs associated with our potential products, including the cost and timing of expanding our marketing and sales capabilities;
	•	the terms and timing of any potential future collaborations, licensing or other arrangements that we may establish;
	•	cash requirements of any future acquisitions and/or the development of other drug candidates;
	•	the costs of operating as a public company;
	•	the cost and timing of completion of commercial-scale outsourced manufacturing activities; and
	•	the time and cost necessary to respond to technological and market developments.

Until we can generate a sufficient amount of revenue, we may finance future cash needs through public or private equity offerings, debt financings, collaborations and strategic alliances. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. General market conditions or the market price of our common stock may not support capital raising transactions such as an additional public or private offering of our common stock or other securities. In addition, our ability to raise additional capital may be dependent upon our common stock being quoted on The Nasdaq Global Select Market or upon obtaining stockholder approval to issue a sufficient number of shares of our common stock. There can be no assurance that we will be able to satisfy the criteria for continued listing on The Nasdaq Global Select Market or that we will be able to obtain stockholder approval of such stock issuances if it is necessary. If adequate funds are not available to us on acceptable terms, or at all, we may be required to delay or reduce the scope of, or eliminate, one or more of our research or development programs or our commercialization efforts. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. In addition, if we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or drug candidates or to grant licenses on terms that may not be favorable to us.

We believe that our existing cash and cash equivalents and short-term investments will not be sufficient to enable us to complete all necessary development or commercially launch our proprietary drug candidates. If we are unable to raise capital when needed or on attractive terms, we will be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. Our inability to obtain additional funding when needed could seriously harm our business.

We entered into a $50.0 million senior secured loan agreement, which subjects the Company to significant interest rate and credit risk.

On June 29, 2018, the Company entered into a 5-year $50.0 million loan agreement with an affiliate of Perceptive Advisors LLC (“Perceptive”), which closed on July 3, 2018, bearing interest at a floating per annum rate equal to the London Interbank Offering Rate (“LIBOR”) (with a floor of 2%) plus 9%. Thus, a change in the short-term interest rate environment (especially a material change) could have a material adverse effect on our business, financial condition, cash flows and results of operations and could cause the market value of our common shares to decline. As of June 30, 2019, we did not have any outstanding interest rate swap contracts.

We may not be able to refinance, extend, or repay our substantial indebtedness owed to our senior secured lender, which would have a material adverse effect on our financial condition and ability to continue as a going concern.

We anticipate that we will need to raise a significant amount of debt or equity capital in the future in order to repay our outstanding debt obligations owed to our senior secured lender when they mature on July 3, 2023 and fund our operations. We are required to make monthly interest-only payments with a bullet payment of the principal amount of $50.0 million at maturity. If we are unable to raise sufficient capital to repay these obligations at maturity and we are otherwise unable to extend the maturity dates or refinance these obligations, we would be in default. We cannot provide any assurances that we will be able to raise the necessary amount of capital to repay these obligations or that we will be able to extend the maturity dates or otherwise refinance these obligations. Upon a default on the senior debt, our senior secured lender would have the right to exercise its rights and remedies to collect, which would include foreclosing on our assets. Accordingly, a default would have a material adverse effect on our business and, if our senior secured lender exercises its rights and remedies, we would likely be forced to seek bankruptcy protection.

Covenants in the agreements governing our existing debt agreement restrict the manner in which we conduct our business.

The senior secured loan agreement contains various covenants that limit, subject to certain exemptions, our ability and/or our restricted subsidiaries’ ability to, among other things:

	•	Incur or assume liens or additional debt or provide guarantees in respect of obligations of other persons;
	•	make loans, investments, or acquisitions;
	•	engage in any other business other than the business engaged in on the date of the loan agreement;
	•	pay dividends or make distributions on capital stock by any subsidiary;
	•	make any unscheduled payments on the Company’s existing debt prior to the stated maturity thereof;
	•	sell assets and capital stock of our subsidiaries;
	•	enter into certain transactions with affiliates; and
	•	sell, transfer, license, lease, or dispose of our or our subsidiaries’ assets.

The senior secured loan agreement requires that we maintain a minimum aggregate balance of $4.0 million in cash free and clear of all liens and that we meet certain minimum revenue targets for each quarter during which the loan is outstanding. In addition, the loan agreement is secured by substantially all of our assets and is guaranteed by certain of our subsidiaries, including APD, Athenex Pharmaceuticals LLC (“AP”), and Athenex Pharma Solutions (“APS”).

The restrictions contained in our senior secured loan agreement governing our debt could adversely affect our ability to:

	•	finance our operations;
	•	make needed capital expenditures;
	•	make strategic acquisitions or investments or enter into alliances;
	•	withstand a future downturn in our business or the economy in general;
	•	engage in business activities, including future opportunities, that may be in our interest; and
	•	plan for or react to market conditions or otherwise execute our business strategies.

A breach of any of these covenants could result in a default under the senior secured loan agreement governing our debt. Further, additional indebtedness that we incur in the future may subject us to further covenants. If a default under any such loan agreement is not cured or waived, the default could result in the acceleration of debt, which could require us to repurchase or repay debt prior to the date it is otherwise due and that could adversely affect our financial condition. If we default, Perceptive may seek repayment through our subsidiary guarantors or by executing on the security interest granted pursuant to the loan agreement.

Our ability to comply with the covenants contained in our senior secured loan agreement may be affected by events beyond our control, including prevailing economic, financial, and industry conditions. Even if we are able to comply with all of the applicable covenants, the restrictions on our ability to manage our business in our sole discretion could adversely affect our business by, among other things, limiting our ability to take advantage of financings, mergers, acquisitions, and other corporate opportunities that we believe would be beneficial to us. In addition, our obligations under the loan agreement are secured, on a first-priority basis, and such security interests could be enforced in the event of default by the collateral agent for the loan agreement.

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or drug candidates.

We may seek additional funding through a combination of equity offerings, debt financings, collaborations and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms may include liquidation or other preferences that adversely affect your rights as a holder of our common stock. The incurrence of additional indebtedness or the issuance of certain equity securities could result in increased fixed payment obligations and could also result in certain additional restrictive covenants, such as limitations on our ability to incur additional debt or issue additional equity, limitations on our ability to acquire or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. In addition, issuance of additional equity securities, or the possibility of such issuance, may cause the market price of our common stock to decline. In the event that we enter into collaborations or licensing arrangements in order to raise capital, we may be required to accept unfavorable terms, including relinquishing or licensing to a third party on unfavorable terms our rights to technologies or proprietary drug candidates that we otherwise would seek to develop or commercialize ourselves or potentially reserve for future potential arrangements when we might be able to achieve more favorable terms.

Certain of our executive officers and employees have received grants of stock options and shares of restricted stock, which vest over time. Under certain circumstances, such vesting may be accelerated. The accelerated vesting of stock options and shares of restricted stock could also result in dilution to our existing stockholders and lower the market price of our common stock.

An impairment of goodwill could have a material adverse effect on our results of operations.

Acquisitions frequently result in the recording of goodwill and other intangible assets. As of June 30, 2019, our existing goodwill represented $37.5 million, or 12% of our total assets, primarily as a result of our acquisitions of QuaDPharma, LLC, Comprehensive Drug Enterprises, and Polymed Therapeutics, Inc. and Chongqing Taihao Pharmaceutical Co Ltd. If we complete the CIDAL acquisition, our goodwill is also subject to change. Goodwill is not amortized and is subject to impairment testing at least annually using a fair value based approach. The identification and measurement of goodwill impairment involves the estimation of the fair value of our reporting units. The estimates of fair value of reporting units are based on the best information available as of the date of the assessment and incorporate management assumptions about expected future cash flows and other valuation techniques. Future cash flows can be affected by changes in industry or market conditions, among other factors. The recoverability of goodwill is

evaluated at least annually or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. We cannot accurately predict the amount and timing of any future impairment of assets, and, going forward, we may be required to take goodwill or other asset impairment charges relating to certain of our reporting units. Any such charges would have an adverse effect on our financial results.

Risks Related to Clinical Development of Our Proprietary Drug Candidates

Our primary clinical candidates are still in the development stage and have not yet received regulatory approval, which may make it difficult to evaluate our current business and predict our future performance.

We are a globally-focused biopharmaceutical company formed in November 2003. Our operations to date have focused on organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio and conducting preclinical studies and clinical trials of our drug candidates. We have not yet successfully completed large-scale, pivotal clinical trials for all of our drug candidates, or obtained regulatory approvals for our drug candidates and have not yet established sales and marketing activities necessary for successful commercialization. Consequently, any predictions you make about our future success or viability may not be accurate. In addition, as a developing business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown challenges.

We are focused on the discovery and development of innovative drugs for the treatment of cancers. The fact that we have not yet, among other things, demonstrated our ability to initiate or complete large-scale clinical trials or manufacture drugs at commercial scale, particularly in light of the rapidly evolving cancer treatment field, may make it difficult to evaluate our current business and predict our future performance. These constraints make any assessment of our future success or viability subject to significant uncertainty. We will encounter risks and difficulties frequently experienced by early-stage companies in rapidly evolving fields as we seek to transition to a company capable of supporting commercial activities. If we do not address these risks and difficulties successfully, our business will suffer. We depend substantially on the success of our proprietary drug candidates, which are in pre-clinical and clinical development.

We have a total of 29 planned, or ongoing clinical trials for our drug candidates. We have completed, two Phase 3 clinical trials for tirbanibulin ointment 1%. Our Phase 3 clinical trial for oral paclitaxel and encequidar for the treatment of patients with metastatic breast cancer has completed enrollment. Our business and the ability to generate revenue related to product sales from our proprietary drug candidates will depend on the successful development, regulatory approval and commercialization for the treatment of patients with our drug candidates, which are still in development, and other drugs we may develop. Clinical development is a lengthy and expensive process with an uncertain outcome. The results of pre-clinical studies and early clinical trials of our drug candidates may not be predictive of the results of later-stage clinical trials. In the case of any trials we conduct, results have in the past, and may in the future, fail to meet the desired safety and efficacy endpoints, or differ from earlier trials due to the larger number of clinical trial sites and additional countries and populations involved in such trials. We have invested a significant portion of our efforts and financial resources in the development of our existing drug candidates. The success of our proprietary drug candidates will depend on several factors, including:

	•	successful enrollment in, and completion of, clinical studies;
	•	receipt of regulatory approvals from the FDA, NMPA and other regulatory authorities for our drug candidates;
	•	establishing commercial manufacturing capabilities, either by using our own facilities or making arrangements with third-party manufacturers;
	•	conducting our clinical trials compliantly and efficiently, and in many cases, relying on third parties to do so or, if we complete the acquisition of CIDAL, successfully integrating the CRO capabilities of CIDAL into our business;
	•	obtaining, maintaining and protecting our intellectual property rights, including patent, trade secrets, know-how and regulatory exclusivity;
	•	ensuring we do not infringe, misappropriate or otherwise violate the patent, trade secret or other intellectual property rights of third parties;
	•	competition with other drug candidates and drugs, including existing IV chemotherapy treatments, potential oncology biologics and other oral dosing technologies developed or being developed by competitors and
	•	continued acceptable safety profile for our drug candidates following regulatory approval, if and when received.

If we do not achieve one or more of these requirements in accordance with our business plans or at all, we could experience significant delays in our ability to obtain approval for and/or to successfully commercialize our drug candidates, which would materially harm our business and we may not be able to generate sufficient revenues and cash flows to continue our operations.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and early clinical trials of our drug candidates may not be predictive of the results of later-stage clinical trials. Drug candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, including genetic differences, patient adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. In the case of any trials we conduct, results may differ from early trials due to the larger number of patients, clinical trial sites and additional countries and populations involved in such trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. Our future clinical trial results may not be favorable as previous trials with the same compound, even with the same indication.

We may not be successful in our efforts to identify or discover additional drug candidates. Due to our limited resources and access to capital, we must and have in the past decided to prioritize development of certain product candidates; these decisions may prove to have been wrong and may adversely affect our business.

To date, we have focused our drug discovery efforts on developing our cancer platform, particularly our Orascovery and Src Kinase Inhibition product candidates. If our cancer platform fails to identify potential drug candidates, our business could be materially harmed. Additionally, our management, at the direction of our board of directors, has discretion in prioritizing which product candidates to develop.

Research programs to pursue the development of our drug candidates for additional indications and to identify new drug candidates and disease targets require substantial technical, financial and human resources whether or not we ultimately are successful. Our research programs may initially show promise in identifying potential indications and/or drug candidates, yet fail to yield results for clinical development for a number of reasons, including:

	•	the research methodology used may not be successful in identifying potential indications and/or drug candidates;
	•	potential drug candidates may, after further study, be shown to lack efficacy, have harmful adverse effects or other characteristics that indicate they are unlikely to be effective drugs; or
	•	it may take greater human and financial resources to identify additional therapeutic opportunities for our drug candidates or to develop suitable potential drug candidates through internal research programs than we possess, thereby limiting our ability to diversify and expand our drug portfolio.

Because we have limited financial and managerial resources, we focus on research programs and drug candidates for specific indications. As a result, we may forego or delay pursuit of opportunities with other drug candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities.

Accordingly, there can be no assurance that we will be able to identify additional therapeutic opportunities for our drug candidates or to develop suitable potential drug candidates through internal research programs, which could materially adversely affect our future growth and prospects. We may focus our efforts and resources on potential drug candidates or other potential programs that ultimately prove to be unsuccessful.

If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We and our research partners have from time to time and may in the future experience difficulties in patient enrollment in our clinical trials for a variety of reasons, including:

	•	the availability of a sizeable population of eligible patients;
	•	the design of the trial;
	•	our ability to recruit clinical trial investigators with the appropriate competencies and experience;
	•	competing clinical trials for similar therapies or other new therapeutics;
	•	clinicians’ and patients’ perceptions as to the potential advantages and side effects of the drug candidate being studied in relation to other available therapies,

	•	our ability to obtain and maintain patient consents;
	•	the failure of patients to complete a clinical trial; and
	•	the availability of approved therapies that are similar in mechanism to our drug candidates.

In addition, our clinical trials will compete with other clinical trials for drug candidates that are in the same therapeutic areas as our drug candidates, and this competition will reduce the number and types of patients available to us because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Because the number of qualified clinical investigators is limited, we have conducted and expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites.

Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our drug candidates.

Some of our drug candidates represent a novel approach to cancer treatment, which could result in delays in clinical development, heightened regulatory scrutiny, and delays in our ability to achieve regulatory approval or commercialization, or market acceptance by physicians and patients of our drug candidates.

Some of our drug candidates, particularly those developed through our Orascovery platform, represent a departure from more commonly used methods for cancer treatment, and therefore represent a novel approach that carries inherent development risks. For instance, our Orascovery platform intends to facilitate the delivery of chemotherapy agents orally, as opposed to IV, while our Src Kinase inhibitor candidates operate by a new mechanism of action. To develop our Orascovery platform, we must successfully develop oral formulations of the active ingredients and ensure they can be delivered safely and consistently in capsule form. The need to further develop or modify in any way the protocols related to our drug candidates to demonstrate safety or efficacy may delay the clinical program, regulatory approval or commercialization, if approved. Our Src Kinase inhibitor platform is based on a novel molecule with an additional mechanism of action that is not found in other Src Kinase inhibitors. Because of this, unexpected safety and tolerability concerns may arise during the development process.

In addition, potential patients and their doctors may be inclined to use conventional standard-of-care treatments rather than enroll patients in any future clinical trial or to use our product candidates commercially once approved. This may have a material impact on our ability to generate revenues from our drug candidates. Further, given the novelty of the administration of our drug candidates, hospitals and physicians may prefer traditional treatment methods, may be reluctant to adopt the use of our products or may require a substantial amount of education and training, any of which could delay or prevent acceptance of our products by physicians and patients and materially hinder successful commercialization of our drug candidates.

Our products and product candidates may cause undesirable, or an increase in the frequency of, side effects that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, NMPA or other regulatory authorities. Further, if a product candidate receives marketing approval and we or others identify undesirable side effects caused by the product after the approval, or if drug abuse is determined to be a significant problem with an approved product, a number of potentially significant negative consequences could result, including:

	•	regulatory authorities may withdraw or limit their approval of the product;
	•	regulatory authorities may require the addition of labeling statements, such as a “Black Box warning” or a contraindication;
	•	we may be required to change the way the product is distributed or administered, conduct additional clinical trials or change the labeling of the product;
	•	we may decide to remove the product from the marketplace;
	•	we could be sued and held liable for injury caused to individuals exposed to or taking the product; and
	•	our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing an affected product or product candidate and significantly impact our ability to successfully commercialize or maintain sales of our product or product candidates and generate revenues.

If clinical trials of our drug candidates fail to demonstrate safety and efficacy to the satisfaction of the FDA, NMPA or other regulatory authorities or do not otherwise produce positive results, we may incur costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our drug candidates.

We may experience various unexpected events during, or as a result of, clinical trials that could delay or prevent our ability to receive regulatory approval or commercialize our drug candidates, including:

	•	regulators, institutional review boards (“IRBs”) or ethics committees may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;
	•	clinical trials of our drug candidates may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon drug development programs;
	•	the number of patients required for clinical trials of our drug candidates may be larger than we anticipate, enrollment may be insufficient or slower than we anticipate or patients may drop out at a higher rate than we anticipate;
	•	our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;
	•	we might have to suspend or terminate clinical trials of our drug candidates for various reasons, including a finding of a lack of clinical response or a finding that participants are being exposed to unacceptable health risks;
	•	regulators, IRBs or ethics committees may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements;
	•	the cost of clinical trials of our drug candidates may be greater than we anticipate;
	•	the supply or quality of our drug candidates or other materials necessary to conduct clinical trials of our drug candidates may be insufficient or inadequate; and
	•	our drug candidates may cause adverse events, have undesirable side effects or other unexpected characteristics, causing us or our investigators to suspend or terminate the trials.

If we are required to conduct additional clinical trials or other testing of our drug candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if they raise safety concerns, we may:

	•	be delayed in obtaining regulatory approval for our drug candidates;
	•	not obtain regulatory approval at all;
	•	obtain approval for indications that are not as broad as intended;
	•	have the drug removed from the market after obtaining regulatory approval;
	•	be subject to additional post-marketing testing requirements;
	•	be subject to restrictions on how the drug is distributed or used; or
	•	be unable to obtain reimbursement for use of the drug.

Delays in testing or approvals may result in increases in our drug development costs. We do not know whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all.

Significant clinical trial delays also could shorten any periods during which we have the exclusive right to commercialize our drug candidates or allow our competitors to bring drugs to market before we do and impair our ability to commercialize our drug candidates and may harm our business and results of operations.

Manufacturing risks, including our inability to manufacture API and clinical products used in the clinical trials of our proprietary product candidates could adversely affect our ability to commercialize our product candidates.

Our business strategy depends on our ability to manufacture API in sufficient quantities and on a timely basis so as to meet our needs to manufacture our product candidates for our clinical trials and to meet consumer demand for our future products, while adhering to product quality standards, complying with regulatory requirements and managing manufacturing costs. We are subject to numerous risks relating to our manufacturing capabilities, including:

	•	our inability to manufacture API and clinical products in sufficient quantities to meet the needs of our clinical trials or to commercialize our products;
	•	our inability to manufacture API and clinical products in the event our manufacturing facilities’ operations are suspended indefinitely or terminated due to events beyond our control;
	•	our inability to secure product components in a timely manner, in sufficient quantities or on commercially reasonable terms;
	•	our failure to increase production of products to meet demand;
	•	our inability to modify production lines to enable us to efficiently produce future products or implement changes in current products in response to regulatory requirements;
	•	difficulty identifying and qualifying alternative suppliers for components in a timely manner and
	•	potential damage to or destruction of our manufacturing equipment or manufacturing facility.

In addition, we conduct manufacturing operations at our facility in Chongqing, China to manufacture API and our proprietary product candidates. As a result, our business is subject to risks associated with that facility in particular and doing business in China generally, including:

	•	the possibility of our operations at the Chongqing facility being suspended indefinitely or terminated by an order of the local government due to events beyond our control;
	•	the possibility that the costs of building and maintaining the Chongqing facility exceed the revenue we are able to generate from manufacturing API at the facility;
	•	adverse political and economic conditions, particularly those negatively affecting the trade relationship between the U.S. and China;
	•	trade protection measures, such as tariff increases, and import and export licensing and control requirements;
	•	potentially negative consequences from changes in tax laws;
	•	difficulties associated with the Chinese legal system, including increased costs and uncertainties associated with enforcing contractual obligations in China;
	•	potentially lower protection of intellectual property rights;
	•	unexpected or unfavorable changes in regulatory requirements;
	•	possible patient or physician preferences for more established pharmaceutical products and medical devices manufactured in the U.S. and
	•	difficulties in managing foreign relationships and operations generally.

Operations at our plant in Chongqing, China are currently suspended. We chose to suspend production based on concerns raised by the DEMC related to the location of our plant. The voluntary temporary suspension began in May 2019 and we hope to reach a resolution of the suspension with the DEMC, but we can provide no assurances of when, if at all, production of API will resume at the plant. If we are unable to resume operations at that facility and if we are unable to find alternate suppliers of the product candidates, specifically tirbanibulin, oral paclitaxel and encequidar, we may have to delay our scheduled development of our product candidates, including but not limited to their NDA submissions. If we are unable to perform the clinical testing required to obtain regulatory approval, we will be unable to commercialize our product candidates. In addition, we manufacture API for third parties. If operations at the Chongqing facility remain suspended, we may be unable to fulfill our obligations to timely supply these third parties with API, and we may have to expend additional capital to manufacture API at our other locations.

These risks are likely to be exacerbated by our limited experience with our current products and manufacturing processes. If, as we expect, our need for API increases, or demand for our products increase, we will have to invest additional resources to purchase components, hire and train employees and enhance our manufacturing processes and may have to use alternate suppliers of API to meet our needs. If we fail to increase our production capacity efficiently, our sales may not increase in line with our forecasts and our operating margins could fluctuate or decline. Any of these factors may affect our ability to manufacture our product and could reduce our revenues and profitability.

Risks Related to Obtaining Regulatory Approval for Our Drug Candidates

The regulatory approval processes of the FDA, NMPA and other regulatory authorities are lengthy, time consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our drug candidates, our business will be substantially harmed.

The time required to obtain approval by the FDA, NMPA and other regulatory authorities in jurisdictions where we seek such approval is unpredictable but typically takes many years following the commencement of preclinical studies and clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, approval policies, regulations or the type and amount of clinical data necessary to gain approval may change during the course of a drug candidate’s clinical development and may vary among jurisdictions. We have not obtained regulatory approval for any drug candidate, and it is possible that none of our existing drug candidates or any drug candidates we may discover, in-license or acquire and seek to develop in the future will ever obtain regulatory approval.

Our drug candidates could fail to receive regulatory approval from the FDA, NMPA or another regulatory authority for many reasons, including:

	•	disagreement with the design or implementation of our clinical trials;
	•	failure to demonstrate that a drug candidate is safe and effective for its proposed indication;
	•	failure of clinical trial results to meet the level of statistical significance required for approval;
	•	failure to demonstrate that a drug candidate’s clinical and other benefits outweigh its safety risks;
	•	disagreement with our interpretation of data from preclinical studies or clinical trials;
	•	the insufficiency of data collected from clinical trials of our drug candidates to support the submission and filing of a new drug application, or NDA, or other submission or to obtain regulatory approval;
	•	the FDA, NMPA or another regulatory authority’s finding of deficiencies related to the product, manufacturing processes or facilities of ours or of third-party manufacturers with whom we contract for clinical and commercial supplies; and
	•	changes in approval policies or regulations that render our preclinical and clinical data insufficient for approval.

The FDA, NMPA or a regulatory authority in another jurisdiction may require more information, including additional preclinical or clinical data, to support approval, which may delay or prevent approval in those territories and our commercialization plans, or we may decide to abandon the development program. If we were to obtain approval, regulatory authorities may approve any of our drug candidates for fewer or more limited indications than we request, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a drug candidate with a label that is not desirable for the successful commercialization of that drug candidate. In addition, if our drug candidate produces undesirable side effects or safety issues, the FDA may require the establishment of REMS, or the NMPA or a regulatory authority may require the establishment of a similar strategy, that may, for instance, significantly restrict distribution of our drug candidates and impose burdensome implementation requirements on us. Any of the foregoing scenarios could materially harm the commercial prospects of our drug candidates.

The approval process for pharmaceutical products outside the U.S. varies among countries and may limit our ability to develop, manufacture and sell our products internationally. Failure to obtain marketing approval in international jurisdictions would prevent our product candidates from being marketed abroad.

In order to market and sell our products internationally, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and may involve additional testing. We may conduct clinical trials for, and seek regulatory approval to market, our product candidates in countries other than the U.S. and China. Depending on the results of clinical trials and the process for obtaining regulatory approvals in other countries, we may decide to first seek regulatory approvals of a product candidate in countries other than the U.S., or we may simultaneously seek regulatory approvals in the U.S. and other countries. If we seek marketing approval for a product candidate outside the U.S., we will be subject to the regulatory requirements of health authorities in each country in which we seek approval. With respect to marketing authorizations

in China, we will be required to seek regulatory approval from the NMPA. For marketing approval in Europe, we will seek to obtain marketing approval from the European Medicines Agency (“EMA”). The approval procedure varies among regions and countries and may involve additional testing, and the time required to obtain approval may differ from that required to obtain FDA approval.

Obtaining regulatory approvals from health authorities in countries outside the U.S. is likely to subject us to all of the risks associated with obtaining FDA approval described above. In addition, marketing approval by the FDA does not ensure approval by the health authorities of any other country, and marketing approvals by foreign health authorities do not ensure a similar approval by the FDA.

We are conducting, and may in the future conduct, clinical trials for our product candidates in sites outside the U.S. and the FDA may not accept data from trials conducted in such locations.

We have conducted, and may in the future conduct, certain of our clinical trials outside of the U.S. Although the FDA may accept data from clinical trials conducted outside the U.S., acceptance of this data is subject to certain conditions imposed by the FDA. There can be no assurance the FDA will accept data from any clinical trials we conduct outside of the U.S. If the FDA does not accept the data from any of our clinical trials conducted outside the U.S., it would likely result in the need for additional clinical trials, which would be costly and time-consuming and could delay or prevent the commercialization of any of our product candidates.

Regulatory approval may be substantially delayed or may not be obtained for one or all of our drug candidates for a variety of reasons.

We may be unable to complete development of our drug candidates on schedule, if at all. The completion of the studies for our drug candidates will require funding beyond our current resources. In addition, if regulatory authorities require additional time or studies to assess the safety or efficacy of our drug candidates, we may not have or be able to obtain adequate funding to complete the necessary steps for approval for any or all of our drug candidates. Preclinical studies and clinical trials required to demonstrate the safety and efficacy of our drug candidates are time consuming and expensive and together take several years or more to complete. For example, our current lead product candidate, oral paclitaxel and encequidar, which is in the final stages of a Phase 3 clinical trial, has been in development since 2011. Delays in clinical trials, regulatory approvals or rejections of applications for regulatory approval in the U.S., Taiwan, New Zealand, China or other jurisdictions may result from many factors, including:

	•	our inability to obtain sufficient funds required for a clinical trial;
	•	regulatory requests for additional analyses, reports, data, non-clinical and preclinical studies and clinical trials;
	•	regulatory questions regarding interpretations of data and results and the emergence of new information regarding our drug candidates or other products;
	•	clinical holds, other regulatory objections to commencing or continuing a clinical trial or the inability to obtain regulatory approval to commence a clinical trial in countries that require such approvals;
	•	failure to reach agreement with the FDA, NMPA or other regulators regarding the scope or design of our clinical trials;
	•	delay or failure in obtaining authorization to commence a trial or inability to comply with conditions imposed by a regulatory authority regarding the scope or design of a clinical trial;
	•	our inability to enroll and retain a sufficient number of patients who meet the inclusion and exclusion criteria in a clinical trial;
	•	our inability to conduct a clinical trial in accordance with regulatory requirements or our clinical protocols;
	•	clinical sites and investigators deviating from trial protocol, failing to conduct the trial in accordance with regulatory requirements, or dropping out of a trial;
	•	withdrawal of clinical trial sites from our clinical trials as a result of changing standards of care or the ineligibility of a site to participate in our clinical trials;
	•	inability to identify and maintain a sufficient number of trial sites, many of which may already be engaged in other clinical trial programs, including some that may be for the same indication;
	•	failure of our third-party clinical trial managers to satisfy their contractual duties or meet expected deadlines;
	•	delay or failure in adding new clinical trial sites;
	•	ambiguous or negative interim results, or results that are inconsistent with earlier results;

	•	unfavorable or inconclusive results of clinical trials and supportive non-clinical studies, including unfavorable results regarding safety or effectiveness of drug candidates during clinical trials;
	•	feedback from the FDA, NMPA, IRB, the Data and Safety Monitoring Board (“DSMB”) or comparable entities, or results from earlier stage or concurrent preclinical studies and clinical trials, that might require modification to the protocol;
	•	unacceptable risk-benefit profile or unforeseen safety issues or adverse side effects;
	•	decision by the FDA, NMPA, IRB, comparable entities or the Company, or recommendation by a DSMB or comparable entity, to suspend or terminate clinical trials at any time for safety issues or for any other reason;
	•	failure to demonstrate a benefit from using a drug candidate;
	•	lack of adequate funding to continue the clinical trial due to unforeseen costs or other business decisions;
	•	our inability to reach agreements on acceptable terms with prospective CROs and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;
	•	our inability to obtain approval from IRBs or ethics committees to conduct clinical trials at their respective sites;
	•	manufacturing issues, including problems with manufacturing or timely obtaining from third parties sufficient quantities of a drug candidate for use in a clinical trial; and
	•	difficulty in maintaining contact with patients during the study or after treatment, resulting in incomplete data.

Changes in regulatory requirements and guidance may also occur, and we may need to amend clinical trial protocols submitted to applicable regulatory authorities to reflect these changes. Amendments may require us to resubmit clinical trial protocols to IRBs or ethics committees for re-examination, which may impact the costs, timing or successful completion of a clinical trial.

According to the Provisions for Drug Registration and the Reform Plan Regarding the Category of the Registration of Chemical Medicines promulgated by the NMPA, the registrations of chemical medicines in China are divided into five categories, among which, Category 1 means the registration of innovative drugs that are not marketed either domestically or abroad, and Category 5 for the registration of drugs that have been marketed abroad and are being registered for marketing in China for the first time. Our drug candidates are all new therapeutic agents and we have built both research and development, clinical trial capacities, and commercial manufacturing facilities in China. As a result, we expect all of our current drug candidates to fall within the Category 1 application process but cannot be sure we will be granted or be able to maintain Category 1 designation. We believe the local drug registration pathway, Category 1, is a faster and more efficient path to obtain approval in the Chinese market than the drug registration pathway for imported drugs under Category 5. Category 5 drug candidates may not qualify to benefit from fast track review with priority at the CTA stage. Category 1 drugs receive special examination and approval treatment. The advantages of such treatment include a separate pathway for Category 1 application to queue up for examination by the Center for Drug Evaluation of the NMPA, or the CDE, and a working mechanism for communication with the applicants for discussion of relevant technical issues.

According to the Opinions on Implementing Priority Review and Approval to Encourage Drug Innovation, the “Prioritized Evaluation and Approval Opinions,” which was promulgated and implemented as of December 21, 2017 by the NMPA, the NMPA conducts priority review and approval for the registration applications of Category 1 drugs. On May 17, 2018, the NMPA and National Health Commission, or NHC issued the Announcement on Optimizing the Review and Approval of Drug Registration, which further clarifies that a priority review and approval mechanism will be available. The NMPA will allot more resource to accelerate the review and approval process for the registration of Category 1 drugs.

The applications for Category 1 drugs are handled with higher priority and enhanced communications with the CDE. Compared with Category 5 drugs, Category 1 drugs are qualified to apply for special examination and approval at both the CTA stage and the production registration application stage. If the special examination and approval are granted at the CTA stage, such treatment will apply to the production registration application stage without further approval. During the CTA stage, reduction or exemption of clinical trial may be available if Category 1 drugs are for orphan diseases or other special diseases. The advantages also include, by providing priority resources, shortening time limits to review and exam applications of Category 1 drugs’ clinical trials and of production registration, and to handle document submission and approval process. We cannot be sure that the NMPA will grant such priority treatment to any of our drugs candidates.

If we experience delays in the completion of, or the termination of, a clinical trial, of any of our drug candidates, the commercial prospects of our drug candidates will be harmed, and our ability to generate revenues from the sale of any of those drug candidates will be delayed. In addition, any delays in completing our clinical trials will increase our costs, slow down our drug candidate development and approval process, and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may harm our business, financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our drug candidates.

Our drug candidates have caused and may cause undesirable adverse events or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following any regulatory approval.

Undesirable adverse events related to our drug candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials that would preclude approval of our drug candidates by the FDA, NMPA, or another regulatory authority or, if approved, could result in a more restrictive label. Results of our trials could reveal a high and unacceptable severity or prevalence of adverse events. In such an event, our trials could be suspended or terminated and the FDA, NMPA or other regulatory authorities could order us to cease further development of, or deny approval of, our drug candidates for any or all targeted indications. Drug-related adverse events could affect patient recruitment or the ability of enrolled subjects to complete the trial, and could result in potential product liability claims. Any of these occurrences may significantly harm our reputation, business, financial condition and prospects.

In our clinical studies to date, we have observed the following serious adverse effects that were deemed to be possibly, likely or definitely related to each of our product candidates:

	•	Oral paclitaxel and encequidar - severe neutropenia, febrile neutropenia, sepsis, septic shock, altered state of consciousness, hypokalemia and cardiac arrest, dehydration, pneumonia, death, nausea, vomiting, diarrhea, fatigue, anorexia, alopecia and acute gastroenteritis;
	•	Oral irinotecan and encequidar - diarrhea, rash, gastrointestinal hemorrhage, vomiting, nausea, asthenia, neutropenia, anorexia, increased alanine aminotransferase, increased aspartate aminotransferase, enteritis, decreased neutrophil count and clostridium difficile infection;
	•	Tirbanibulin oral - allergic reaction, bacteremia, rash, syncope, perivascular dermatitis, neutropenic fever, hyponatremia, failure to thrive, hypersensitivity, lower extremity edema, mucositis, neutropenia, pancytopenia, thrombocytopenia, seizure and motor vehicle accident, embolic stroke, pneumonitis, fever, acute kidney injury, increased bilirubin and albumin levels, decreased blood platelet count, abdominal pain, arm pain, pain at the base of the neck, pyrexia, chills, rigors, tachypenea, oxygen desaturation, pneumonia, anemia, elevated ALT and AST, dehydration, leukopenia and tremor; and
	•	KX-02 - pulmonary embolism; thromboembolic event, hyperuricemia and nausea.

Additionally, if one or more of our drug candidates receives regulatory approval, and we or others later identify undesirable side effects caused by such drugs, a number of potentially significant negative consequences could result, including:

	•	we may suspend marketing of the drug;
	•	regulatory authorities may withdraw approvals of the drug;
	•	regulatory authorities may require additional warnings on the label;
	•	we may be required to develop a REMS for the drug or, if a REMS is already in place, to incorporate additional requirements under the REMS, or to develop a similar strategy as required by a regulatory authority;
	•	we may be required to conduct post-marketing studies;
	•	we could be sued and held liable for harm caused to subjects or patients; and
	•	our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular drug candidate, if approved, and could significantly harm our business, results of operations and prospects.

We may seek Orphan Drug Designation for some of our drug candidates, and we may be unsuccessful.

We have received Orphan Drug Designation from the FDA for our proprietary product candidates KX2-361 for the treatment of glioma and oral paclitaxel and encequidar for the treatment of angiosarcomas. As part of our business strategy, we may seek Orphan Drug Designation for our product candidates, and we may be unsuccessful. Regulatory authorities in some jurisdictions, including the U.S. and Europe, may designate drugs for relatively small patient populations as orphan drugs or medicines, respectively. Under the Orphan Drug Act, the FDA may designate a drug as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a disease with a patient population of fewer than 200,000 individuals in the U.S., or a patient population greater than 200,000 in the U.S. where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the U.S. In Europe, the EMA will designate orphan status for a disease which affect less than five people per 10,000 individuals.

Generally, if a drug with an Orphan Drug Designation subsequently receives the first regulatory approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the FDA or EMA from approving another marketing application for the same drug for the same indication during the period of exclusivity, with certain limited exceptions. The applicable post-approval exclusivity period is seven years in the U.S. and ten years in Europe. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for Orphan Drug Designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan Drug Exclusivity may be lost if the FDA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. Orphan designations for medicines in the U.S. and Europe also benefit from incentives such as reduced fees and protocol assistance.

Even if we obtain Orphan Drug Exclusivity for a drug candidate, exclusivity may not effectively protect the drug candidate from competition because different drugs can be approved for the same condition and the same drugs can be approved for a different condition but used off-label for any orphan indication we may obtain. Even after an orphan drug is approved, the FDA may subsequently approve a different drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care.

Even if we receive regulatory approval for our drug candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our drug candidates.

If our drug candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, conduct of post-marketing studies, and submission of safety, efficacy and other post-marketing information, including both federal and state requirements in the U.S. and requirements of regulatory authorities.

Manufacturers and manufacturers’ facilities are required to comply with extensive requirements of the FDA, NMPA and regulatory authorities, including, in the U.S., ensuring that quality control and manufacturing procedures conform to current cGMP regulations. As such, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any NDA or other marketing application, and previous responses to inspection observations. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

Any regulatory approvals that we receive for our drug candidates may be subject to limitations on the approved indicated uses for which the drug may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials and surveillance to monitor the safety and efficacy of the drug candidate. The FDA may also require a REMS program as a condition of approval of one or more of our drug candidates, which could entail requirements for long-term patient follow-up, a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA, NMPA or a regulatory authority approves our drug candidates, we will have to comply with requirements including, for example, submissions of safety and other post-marketing information and reports, registration, and continued compliance with cGMPs and GCPs for any clinical trials that we conduct post-approval.

The FDA may impose consent decrees or withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the drug reaches the market. Later discovery of previously unknown problems with our drug candidates, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-marketing studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

	•	restrictions on the marketing or manufacturing of our drugs, withdrawal of the product from the market, or voluntary or mandatory product recalls;
	•	fines, untitled or warning letters, or holds on clinical trials;
	•	refusal by the FDA to approve pending applications or supplements to approved applications filed by us or suspension or revocation of license approvals;
	•	product seizure or detention, or refusal to permit the import or export of our drug candidates and
	•	injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA, NMPA and other regulatory authorities actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. The policies of the FDA, NMPA and of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our drug candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the U.S. or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any regulatory approval that we may have obtained, and we may not achieve or sustain profitability.

In addition, if we were able to obtain accelerated approval of any of our drug candidates, the FDA would require us to conduct a confirmatory study to verify the predicted clinical benefit and additional safety studies. Other regulatory authorities outside the U.S., such as the NMPA, may have similar requirements. The results from the confirmatory study may not support any clinical benefit, which would result in the approval being withdrawn. While operating under accelerated approval, we will be subject to certain restrictions that we would not be subject to upon receiving regular approval.

Risks Related to Commercialization of Our Drug Candidates

If we are not able to obtain, or experience delays in obtaining, required regulatory approvals, we will not be able to commercialize our drug candidates, and our ability to generate revenue will be materially impaired.

We currently do not have any proprietary drug candidates that have gained regulatory approval for sale in the U.S., China or any other country, and we cannot guarantee that we will ever obtain regulatory approval for marketable proprietary drugs. Our business is substantially dependent on our ability to complete the development of, obtain regulatory approval for and successfully commercialize drug candidates in a timely manner. We cannot commercialize drug candidates without first obtaining regulatory approval to market each drug from the FDA, NMPA or regulatory authorities in the relevant jurisdictions. Our proprietary drug candidates are currently undergoing various phases of FDA clinical trials. We cannot predict whether these trials and future trials will be successful or whether regulators will agree with our conclusions regarding the preclinical studies and clinical trials we have conducted to date.

Before obtaining regulatory approvals for the commercial sale of any drug candidate for a target indication, we must demonstrate in preclinical studies and well-controlled clinical trials, and, with respect to approval in the U.S., to the satisfaction of the FDA, that the drug candidate is safe and effective for use for that target indication and that the manufacturing facilities, processes and controls are adequate. An NDA must include extensive preclinical and clinical data and supporting information to establish the drug candidate’s safety and effectiveness. The NDA must also include significant information regarding the chemistry, manufacturing and controls for the drug. Obtaining approval of an NDA is a lengthy, expensive and uncertain process, and approval may not be obtained. If we submit an NDA to the FDA, the FDA decides whether to accept or reject the submission for filing. We cannot be certain that any submissions will be accepted for filing and review by the FDA.

Regulatory authorities outside of the U.S., such as the regulatory authorities in emerging markets, also have requirements for approval of drugs for commercial sale with which we must comply prior to marketing in those areas. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our drug candidates. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries and obtaining regulatory approval in one country does not

mean that regulatory approval will be obtained in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking non-U.S. regulatory approval could require additional non-clinical studies or clinical trials, which could be costly and time-consuming. The non-U.S. regulatory approval process may include all of the risks associated with obtaining FDA approval and other risks specific to the relevant jurisdiction. For all of these reasons, we may not obtain non-U.S. regulatory approvals on a timely basis, if at all.

If we are unable to obtain regulatory approval for our drug candidates in one or more jurisdictions, or any approval contains significant limitations, our target market will be reduced and our ability to realize the full market potential of our drug candidates will be harmed. Furthermore, if we are not able to obtain, or experience delays in obtaining, required regulatory approvals, we will not be able to commercialize our drug candidates, and our ability to generate revenue will be materially impaired.

Even if any of our drug candidates receives regulatory approval, they may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

If any of our drug candidates receives regulatory approval, they may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community. For example, current cancer treatments like chemotherapy and radiation therapy are well established in the medical community, and doctors may continue to rely on these treatments to the exclusion of our drug candidates. In addition, physicians, patients and third-party payors may prefer other novel products to ours, and we may experience difficulties gaining acceptance for our orally administered drug candidates. We are also subject to regulatory restrictions on how we market our drug candidates. If our drug candidates do not achieve an adequate level of acceptance, we may not generate significant product sales revenues, and we may not become profitable. The degree of market acceptance of our drug candidates, if approved for commercial sale, will depend on a number of factors, including:

	•	the clinical indications for which our drug candidates are approved;
	•	physicians, hospitals, cancer treatment centers and patients considering our drug candidates as a safe and effective treatment;
	•	the potential and perceived advantages of our drug candidates over alternative treatments;
	•	the prevalence and severity of any side effects;
	•	product labeling or product insert requirements of the FDA, NMPA or other regulatory authorities;
	•	limitations or warnings contained in the labeling approved by the FDA, NMPA or other regulatory authorities;
	•	the timing of market introduction of our drug candidates as well as competitive drugs;
	•	the cost of treatment in relation to alternative treatments;
	•	the amount of upfront costs or training required for physicians to administer our drug candidates;
	•	obtaining optimal pricing for products in key global markets;
	•	the availability of adequate coverage, reimbursement and pricing by third-party payors and government authorities (including U.S. federal healthcare programs);
	•	the willingness of patients to pay out-of-pocket in the absence of coverage and reimbursement by third-party payors and government authorities;
	•	relative convenience and ease of administration, including as compared to alternative treatments and competitive therapies;
	•	the emergence of new biomarker-driven therapies as alternatives to chemotherapy; and
	•	the effectiveness of our sales and marketing efforts.

If our drug candidates are approved but fail to achieve market acceptance among physicians, patients, hospitals, cancer treatment centers or others in the medical community, we will not be able to generate significant revenue. Even if our drugs achieve market acceptance, we may not be able to maintain that market acceptance over time if new products or technologies are introduced that are more favorably received than our drugs, are more cost effective or render our drugs obsolete.

Our manufacturing experience is limited and any failure by us to manufacture our products for commercial sale after receiving FDA approval would materially impact our revenue and financial condition.

The manufacture of drugs for commercial sale is subject to regulation by the FDA under cGMP regulations and by other regulators under other laws and regulations. We cannot assure you that we will continue to manufacture our products under cGMP regulations or other laws and regulations in sufficient quantities for commercial sale, or in a timely or economical manner.

Our manufacturing facilities require specialized personnel and are expensive to operate and maintain. Any delay in the regulatory approval or market launch of product candidates to be manufactured in these facilities will require us to continue to operate these expensive facilities and retain specialized personnel, which may increase our expected losses.

Through our public-private partnerships, additional cGMP manufacturing facilities for our use are currently being built in Dunkirk, New York and Chongqing, China. Our facility in Dunkirk, New York is being built pursuant to an agreement with FSMC. Under the current arrangement, we will select and hire contractors for the project and oversee the development of the Dunkirk facility. ESD, the parent entity of FSMC, is responsible for the costs of construction and all equipment for the facility, up to an aggregate of $200 million, and ESD, not us, will own the facility and equipment. We have limited experience in overseeing the development of such a facility and we may not be able to complete the development within the timeframe expected, within the expected budget, or at all. If development of the Dunkirk facility is delayed or not completed it could materially adversely affect our operations and financial results.

Additionally, upon completion, both the Dunkirk and Chongqing facilities will need to be cGMP validated prior to operating. Validation is a lengthy process that must be completed before we can manufacture under cGMP guidelines. We cannot guarantee that the FDA or foreign regulatory agencies will approve any of the other facilities or, once they are approved, that such facilities will remain in compliance with cGMP regulations.

The manufacture of pharmaceutical products is a highly complex process in which a variety of difficulties may arise from time to time. We may not be able to resolve any such difficulties in a timely fashion, if at all. If anything were to interfere with the continuing manufacturing operations in our facilities, it could materially adversely affect our business and financial condition.

Currently, many of our product candidates are manufactured in small quantities for use in clinical trials. We cannot assure you that we will be able to successfully scale up the manufacture of each of our product candidates in a timely or economical manner, or at all. If any of these product candidates are approved by the FDA or other drug regulatory authorities for commercial sale, we will need to manufacture them in larger quantities. If we are unable to successfully scale up our manufacturing capacity, the regulatory approval or commercial launch of such product candidate may be delayed or there may be a shortage in supply of such product candidate.

If we fail to develop manufacturing capacity and experience, fail to continue to contract for manufacturing on acceptable terms, or fail to manufacture our product candidates economically on a commercial scale or in accordance with cGMP regulations, our development programs will be materially adversely affected. This may result in delays in receiving FDA or foreign regulatory approval for one or more of our product candidates or delays in the commercial production of a product that has already been approved. Any such delays could materially adversely affect our business and financial condition.

The manufacture of API is highly regulated by FDA, NMPA and other regulatory bodies and is subject to current good manufacturing practice requirements and to inspection by such regulators, which may result in adverse findings and actions against certain API manufacturing facilities.

API manufacturing facilities are subject to regulation by the applicable regulatory bodies in the place of manufacture as well as the regulatory agency in the country to which the product is exported. For instance, FDA’s cGMP regulations apply to these facilities and violation of these, or other, regulations may result in adverse action against the facility, including cessation of manufacturing activities. Our API manufacturing facilities in Chongqing are also subject to regulation by the NMPA. In addition, the Chongqing plant’s operations are currently suspended based on concerns raised by the DEMC related to the location of our plant. If the FDA, NMPA, DEMC or other regulators discover a problem at one facility, we may be subject to increased scrutiny and/or adverse actions across our operations, including fines or orders to cease manufacturing, which could have a material impact on our operations, clinical development, regulatory approval process, business strategy or results of operations.

We have limited experience in marketing proprietary drug products. If we are unable to establish such marketing and sales capabilities or enter into agreements with third parties to market and sell our proprietary drug candidates, we may not be able to generate sales revenue from such products.

We have limited sales, marketing and commercial product experience. We intend to continue to develop our in-house commercial organization and sales force for such products, which will require significant capital expenditures, management resources and time. We will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing and sales personnel.

If we are unable to establish internal sales, marketing and commercial distribution capabilities for our proprietary drug candidates, we will need to pursue collaborative arrangements for the sales and marketing of our proprietary drugs. However, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third parties, which may not be successful. We may have less control over the marketing and sales efforts of such third parties which may present fraud and abuse and other regulatory considerations, and our revenue from product sales may be lower than if we had commercialized our proprietary drug candidates ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts of our proprietary drug candidates.

There can be no assurance that we will be able to develop our in-house sales and commercial distribution capabilities or establish or maintain relationships with third-party collaborators to successfully commercialize any proprietary product, and as a result, we may not be able to generate sales revenue from such products.

We face substantial competition, and our competitors may discover, develop or commercialize competing drugs before or more successfully than we do.

The development and commercialization of new drugs is highly competitive. We face competition with respect to our current drug candidates and will face competition with respect to any drug candidates that we may seek to develop or commercialize in the future, from major pharmaceutical companies, specialty pharmaceutical companies and biotechnology companies worldwide. There are a number of large pharmaceutical and biotechnology companies that currently market and sell drugs or are pursuing the development of drugs for the treatment of the types of cancer for which we are developing our drug candidates. Some of these competitive drugs and therapies are based on scientific approaches that are the same as or similar to our approach, and others are based on entirely different approaches. Potential competitors also include academic institutions, government agencies and other public and private research organizations that conduct research, seek patent protection and establish collaborative arrangements for research, development, manufacturing and commercialization.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any drugs that we may develop. Our competitors also may obtain approval from the FDA, NMPA or other regulatory authorities for their drugs more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market and/or slow our regulatory approval.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Even if we are able to commercialize any drug candidates, the drugs may become subject to unfavorable pricing regulations, third party reimbursement practices or healthcare reform initiatives, which could harm our business.

Successful sales of our drug candidates, if approved, depend on the availability of adequate coverage and reimbursement from third-party payors. Patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the U.S., and commercial payors are critical to new drug acceptance.

The regulations that govern regulatory approvals, pricing and reimbursement for new therapeutic products vary widely from country to country. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or licensing approval is granted. In some non-U.S. markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain regulatory approval for a drug in a particular country but be subject to price regulations that delay our commercial launch of the drug and negatively impact the revenues we are able to generate from the sale of the drug in that country. For example, according to the guidance issued in March 2015 by the central government of China, each province will decide which drugs to include in its provincial major illness reimbursement lists and the percentage of reimbursement, based on local funding. Adverse pricing limitations may hinder our ability to recover our investment in one or more drug candidates, even if our drug candidates obtain regulatory approval. For example, in China, according to a statement, Opinions on reforming the review and approval process for pharmaceutical products and medical devices, issued by the State Council in August 2015, the enterprises applying for new drug approval will be required to undertake that the selling price of new drug on Chinese mainland market shall not be higher than the comparable market prices of the product in its country of origin or Chinese neighboring markets, as applicable.

Our ability to commercialize any drugs successfully also will depend in part on the extent to which coverage and reimbursement for these drugs and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s determination that use of a drug is:

	•	a covered benefit under its health plan;
	•	safe, effective and medically necessary;
	•	appropriate for the specific patient;
	•	cost-effective and
	•	neither experimental nor investigational.

We cannot be sure that reimbursement will be available for any drug that we commercialize and, if coverage and reimbursement are available, what the level of reimbursement will be. Reimbursement may impact the demand for, or the price of, any drug for which we obtain regulatory approval. Obtaining reimbursement for our drugs may be particularly difficult because of the higher prices often associated with branded drugs and drugs administered under the supervision of a physician. If reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize any drug candidate that we successfully develop.

In the U.S., no uniform policy of coverage and reimbursement for drugs exists among third-party payors. As a result, obtaining coverage and reimbursement approval of a drug from a government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of our drugs on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Even if we obtain coverage for a given drug, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up evaluations required following the use of our drugs. However, under Medicare Part D—Medicare’s outpatient prescription drug benefit—there are protections in place to ensure coverage and reimbursement for oncology products and all Part D prescription drug plans are required to cover substantially all anti-cancer agents.

The State Council required central and provincial authorities across China to promote a medical insurance program for major illnesses, which targets covering at least 50% of the medical cost as incurred by treating major illnesses but falls out of the coverage of the basic insurance programs. The State Council requires provincial authorities to increase reimbursement rates over the next three years.

We intend to seek approval to market our drug candidates in the U.S., China and other selected jurisdictions. If we obtain approval in one or more non-U.S. jurisdictions for our drug candidates, we will be subject to rules and regulations in those jurisdictions. In some non-U.S. countries, the pricing of drugs and biologics is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after obtaining regulatory approval of a drug candidate. In addition, market acceptance and sales of our drug candidates will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our drug candidates and may be affected by existing and future health care reform measures.

We intend to test and market our drugs, if approved, in a variety of international markets and we are exploring the licensing of commercialization rights or other forms of collaboration worldwide, which exposes us to additional risks of conducting business in additional international markets.

We conduct business operations in regions including the U.S., China, Taiwan, New Zealand and the United Kingdom, and other non-U.S. markets, including certain countries in Latin America, are an important component of our growth strategy. If we fail to obtain licenses or enter into collaboration arrangements with third parties in these markets, or if these parties are not successful, our revenue-generating growth potential will be adversely affected.

Moreover, international business relationships subject us to additional risks that may materially adversely affect our ability to attain or sustain profitable operations, including:

	•	initiatives to develop an international sales, marketing and distribution organization may increase our expenses, divert our management’s attention from the acquisition or development of drug candidates or cause us to forgo profitable licensing opportunities in these geographies;
	•	efforts to enter into collaboration or licensing arrangements with third parties in connection with our international sales, marketing and distribution efforts may increase our expenses or divert our management’s attention from the acquisition or development of drug candidates;
	•	changes in a specific country’s or region’s laws, regulations or political and cultural climate or economic condition;
	•	differing regulatory requirements for drug approvals and marketing internationally;
	•	difficulty of effective enforcement of contractual provisions and intellectual property rights in local jurisdictions;
	•	potentially reduced protection for intellectual property rights;
	•	potential conflicting third-party patent or other intellectual property rights;
	•	unexpected changes in tariffs, trade barriers and regulatory requirements, such as Export Administration Regulations promulgated by the U.S. Department of Commerce and fines, penalties or suspension or revocation of export privileges;
	•	economic weakness, including inflation or political instability, particularly in non-U.S. economies and markets;
	•	compliance with tax, employment, immigration and labor laws for employees traveling abroad;
	•	the effects of applicable non-U.S. tax structures and potentially adverse tax consequences;
	•	currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incidental to doing business in another country;
	•	workforce uncertainty and labor unrest, particularly in non-U.S. countries where labor unrest is more common than in the U.S.;
	•	the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts to import goods from a non-U.S. market with low or lower prices rather than buying them locally;
	•	failure of our employees and contracted third parties to comply with Office of Foreign Asset Control rules and regulations and the Foreign Corrupt Practices Act;
	•	production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad and
	•	business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters, including earthquakes, volcanoes, typhoons, floods, hurricanes and fires.

These and other risks may materially adversely affect our ability to obtain or sustain revenue from international markets.

The use of legal, regulatory, and legislative strategies by both brand and generic competitors, including but not limited to “authorized generics” and regulatory petitions, as well as the potential impact of proposed and newly enacted legislation, may increase costs associated with the introduction or marketing of our generic products, could delay or prevent such introduction, and could adversely affect our results of operations.

Our competitors, both branded and generic, often pursue strategies to prevent, delay, or eliminate competition from generic alternatives to branded products. These strategies include, but are not limited to:

	•	entering into agreements whereby other generic companies will begin to market an authorized generic, a generic equivalent of a branded product, at the same time or after generic competition initially enters the market;
	•	launching a generic version of their own branded product prior to or at the same time or after generic competition initially enters the market;
	•	filing petitions with the FDA or other regulatory bodies seeking to prevent or delay approvals, including timing the filings so as to thwart generic competition by causing delays of our product approvals;
	•	seeking to establish regulatory and legal obstacles that would make it more difficult to demonstrate bioequivalence or to meet other requirements for approval, and/or to prevent regulatory agency review of applications, such as through the establishment of patent linkage (laws and regulations barring the issuance of regulatory approvals prior to patent expiration);
	•	initiating legislative or other efforts to limit the substitution of generic versions of brand pharmaceuticals;
	•	filing suits for patent infringement and other claims that may delay or prevent regulatory approval, manufacture, and/or scale of generic products;
	•	introducing “next-generation” products prior to the expiration of market exclusivity for the reference product, which often materially reduces the demand for the generic or the reference product for which we seek regulatory approval;
	•	persuading regulatory bodies to withdraw the approval of brand name drugs for which the patents are about to expire and converting the market to another product of the brand company on which longer patent protection exists;
	•	obtaining extensions of market exclusivity by conducting clinical trials of brand drugs in pediatric populations or by other methods and
	•	seeking to obtain new patents on particular formulations of drugs or methods of administering drugs for which patent protection on the drug itself is about to expire.

If any other actions by our competitors and other third parties to prevent or delay activities necessary to the approval, manufacture, or distribution of our products are successful, our entry into the market and our ability to generate revenues associated with new products may be delayed, reduced, or eliminated, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and/or share price.

Our compounded preparations and the pharmacy compounding industry are subject to regulatory and customer scrutiny, which may impair our growth and sales.

Formulations prepared and dispensed by compounding pharmacies may contain ingredients found in FDA-approved drugs, and such formulations and the compounding thereof are subject to various FDA regulatory requirements. Outsourcing facilities are regulated under Section 503B. Certain compounding pharmacies have been the subject of widespread negative media coverage in recent years, and the actions of these pharmacies have resulted in increased scrutiny of compounding pharmacy activities from the FDA and state governmental agencies. For example, the FDA has in the past requested that a number of compounding pharmacies conduct a recall of all non-expired, purportedly sterile drug products and cease sterile compounding operations due to lack of sterility assurance, and additional compounding pharmacies have suspended sterile production or voluntarily recalled certain sterile compounding products after an FDA inspection of the relevant facilities. As a result of this exercise of caution, or due to the absence of FDA approval, though such approval is not required, some physicians may be hesitant to prescribe, and some patients may be hesitant to purchase and use, these compounded formulations.

In addition, an outsourcing facility must meet certain conditions under Section 503B of the FDCA in order for its compounded products to be exempt from the FDCA’s premarket approval requirements and from the FDCA requirement that products be labeled with adequate directions for use; for example, the drug must be compounded by or under the direct supervision of a licensed pharmacist, in a facility registered pursuant to Section 503B of the FDCA and in compliance with cGMP. If our outsourcing facility or any of our compounded products are found not to satisfy the criteria of Section 503B, the marketing of our products absent the FDA approval and/or absent adequate directions for use in the product labeling could render our products adulterated or

misbranded under the FDCA, which could have an adverse effect on our business. Furthermore, if an outsourcing facility compounds drugs using bulk drug substances, such bulk drug substances must either appear on a list established by the FDA of bulk drug substances for which there is a clinical need or be used to compound drugs that appear on a list established by the FDA of drugs for which there is a shortage. The FDA has not yet placed any bulk drug substances on the clinical list; however, the FDA has announced an interim policy pursuant to which bulk drug substances with sufficient supporting information for FDA to evaluate the bulk drug substances may be nominated for inclusion on a Category 1 list and, provided certain conditions are met, the FDA does not intend to enforce against such outsourcing facilities pending evaluation of the Category 1 substances for inclusion on the FDA’s list of bulk drug substances for which there is a clinical need. In addition to a clinical need determination, the FDA has established guidance on determining whether a product is an essential copy of an FDA approved product. If our products were ever determined to be an essential copy of an FDA approved product, administrative or judicial action could be taken. We use bulk drug substances in the preparation of certain of our compounded products. In the event the FDA’s evaluation of these bulk drug substances results in a determination not to include such substances on the FDA’s list of bulk drug substances for which there is a clinical need, or if FDA were to change its interim policy such that compounding with such bulk drug substances could not proceed while the FDA’s evaluation of the substances is pending or until the FDA has issued its list of bulk drug substances for which there is a clinical need, our ability to continue marketing compounded products subject to Section 503B would be impaired, and our business could be harmed.

We have used bulk vasopressin to produce a compounded ready to use vasopressin product that is preservative free. If we are able to resume selling our compounded vasopressin product, revenues from those sales are expected to be used to fund clinical trials for our cancer drugs in development. However, we have ceased producing and distributing vasopressin following a decision in the DC Court on August 1, 2019. See the risk factor captioned, “If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time-consuming and could prevent or delay us from developing or commercializing our drug candidates.” If we are ultimately unsuccessful in seeking a stay of the DC Court’s decision in the short term, or overturning FDA’s final vasopressin decision in the long term, we would have to abandon this revenue-generating line of business, which would have a material adverse effect on our business, results of operations, financial condition and cash flows.

If a compounded drug formulation provided through our compounding services leads to patient injury or death or results in a product recall, we may be exposed to significant liabilities and reputational harm.

The production, labeling and packaging of compounded drugs is inherently risky. The success of our compounded formulations and pharmacy operations depends to a significant extent upon perceptions of the safety and quality of our products. We could be adversely affected if our formulations are subject to negative publicity. We could also be adversely affected if any of our formulations or other products, any similar products sold by other companies, or any products sold by other compounding outsourcing facilities, prove to be, or are asserted to be, harmful to patients. There are a number of factors that could result in the injury or death of a patient who receives one of our compounded formulations, including quality issues, manufacturing or labeling flaws, improper packaging or unanticipated or improper uses of the products, any of which could result from human or other error. Any of these situations could lead to a recall of, or safety alert relating to, one or more of our products. Similarly, to the extent any of the components of approved drugs or other ingredients used by us to produce compounded formulations have quality or other problems that adversely affect the finished compounded preparations, our sales could be adversely affected. In addition, in the ordinary course of business, we may voluntarily retrieve products in response to a customer complaint. Because of our dependence upon medical and patient perceptions, any adverse publicity associated with illness or other adverse effects resulting from the use or misuse of our products, any similar products sold by other companies or any other compounded formulations, could have a material adverse impact on our business, results of operations and financial condition.

Risks Related to Our Intellectual Property

A significant portion of our intellectual property portfolio currently comprises pending patent applications that have not yet been issued as granted patents, and if our pending patent applications fail to issue our business will be adversely affected. If we are unable to obtain and maintain patent protection for our technology and drugs, our competitors could develop and commercialize technology and drugs similar or identical to ours, and our ability to successfully commercialize our technology and drugs may be adversely affected.

Our success depends in large part on our ability to obtain and maintain patent protection in the U.S., China and other countries with respect to our proprietary technology and drug candidates. We have sought to protect our proprietary position by filing patent applications in the U.S., China and other countries related to novel technologies and drug candidates that we consider important to our business. As of July 25, 2019, we owned more than 150 granted patents and approximately 40 pending patent applications worldwide. The process of obtaining patent protection is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. There can be no assurance

that our pending patent applications will result in issued patents. Moreover, even our issued patents do not guarantee us the right to practice our technology in relation to the commercialization of our platforms’ product candidates. Third parties may have blocking patents that could be used to prevent us from commercializing our patented technologies, platforms and product candidates and practicing our proprietary technology. There can also be no assurance that a third party will not challenge the validity of our patents or that we will obtain sufficient claim scope in those patents, in view of prior art, to prevent a third party from competing successfully with our drug candidates. We may become involved in interference, inter partes review, post grant review, ex parte reexamination, derivation, opposition or similar other proceedings challenging our patent rights or the patent rights of others. Such challenges may result in patent claims being narrowed, invalidated or held unenforceable, which could limit our ability to stop others from using or commercializing similar or identical technology and drug candidates, or limit the duration of the patent protection of our technology and drug candidates. Given the amount of time required for the development, testing and regulatory review of new drug candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing drug candidates similar or identical to ours.

The patent position of biotechnology and pharmaceutical companies is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Changes in patent laws or the interpretation of patent laws in the U.S. and other countries may diminish the value of our patents or narrow the scope of our patent protection. Publications of discoveries in scientific literature often lag behind the actual discoveries, and patent applications in the U.S. and other jurisdictions are typically not published until eighteen months after filing, or in some cases not at all. Therefore, we cannot be certain that we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions.

We may not be able to protect our intellectual property rights throughout the world.

The patent positions of companies like ours are generally uncertain and involve complex legal and factual questions, due to inconsistent policies regarding the scope of claims allowable in patents. Changes in patent laws and rules, either by legislation, judicial decisions, or regulatory interpretation in the U.S. and other countries may diminish our ability to protect our inventions and enforce our intellectual property rights, and more generally could affect the value of our intellectual property.

In addition, the laws of certain non-U.S. countries do not protect intellectual property rights to the same extent as U.S. federal and state laws do. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S., or from selling or importing drugs made using our inventions in and into the U.S. or non-U.S. jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own drugs and further, may export otherwise infringing drugs to non-U.S. jurisdictions where we have patent protection but where enforcement rights are not as strong as those in the U.S. These drugs may compete with our drug candidates and our patent or other intellectual property rights may not be effective or adequate to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in certain jurisdictions, including China. The legal systems of some countries do not favor the enforcement of patents, trade secrets and other intellectual property, particularly those relating to biopharmaceutical products, which could make it difficult in those jurisdictions for us to stop the infringement or misappropriation of our patents or other intellectual property rights, or the marketing of competing drugs in violation of our proprietary rights. Proceedings to enforce our patent and other intellectual property rights in non-U.S. jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business.

Furthermore, such proceedings could put our patents at risk of being invalidated, held unenforceable, or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to assert claims of infringement or misappropriation against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop.

We may become involved in lawsuits to protect or enforce our intellectual property, which could be expensive, time-consuming and unsuccessful and our patent rights relating to our drug candidates could be found invalid or unenforceable if challenged in court or before the U.S. Patent and Trademark Office or comparable non-U.S. authority.

Competitors may infringe our patent rights or misappropriate or otherwise violate our intellectual property rights. To counter infringement or unauthorized use, litigation may be necessary to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity and scope of our own intellectual property rights or the proprietary rights of others. Such litigation can be expensive and time-consuming. Our current and potential competitors may have the ability to dedicate substantially greater resources to enforce and/or defend their intellectual property rights than we can. Accordingly, despite our efforts, we may not be able

to prevent third parties from infringing upon or misappropriating our intellectual property. Litigation could result in substantial costs and diversion of management resources, which could harm our business and financial results. In addition, in an infringement proceeding, a court may decide that patent or other intellectual property rights owned by us are invalid or unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patent or other intellectual property rights do not cover the technology in question. An adverse result in any litigation proceeding could put our patent, as well as any patents that may issue in the future from our pending patent applications, at risk of being invalidated, held unenforceable or interpreted narrowly. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure.

If we initiate legal proceedings against a third party to enforce any patent, or any patents that may issue in the future from our patent applications, that relates to one of our drug candidates, the defendant could counterclaim that such patent rights are invalid or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity or unenforceability are commonplace, and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. Third parties may also raise similar claims before administrative bodies in the U.S. or abroad, even outside the context of litigation. Such mechanisms include ex parte re-examination, inter partes review, post-grant review, derivation and equivalent proceedings in non-U.S. jurisdictions, such as opposition proceedings. Although any party alleging invalidity or unenforceability of our patents has a high burden of proof, nonetheless such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover and protect our drug candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity of our patents, for example, we cannot be certain that there is no invalidating prior art of which we, our patent counsel, and the patent examiner were unaware of during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on certain drug candidates. Such a loss of patent protection could have a material adverse impact on our business.

We may be subject to claims challenging the inventorship of our patents and ownership of other intellectual property.

Although we are not currently experiencing any claims challenging the inventorship of our patents or ownership of our intellectual property, we may in the future be subject to claims that former employees, collaborators or other third parties have an interest in our patents or other intellectual property as inventors or co-inventors. For example, we may have inventorship disputes arise from conflicting obligations of consultants or others who are involved in developing our drug candidates. Litigation may be necessary to defend against these and other claims challenging inventorship. If we fail in defending any such claims, we may lose rights such as exclusive ownership of, or right to use, our patent or other intellectual property rights. Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time-consuming and could prevent or delay us from developing or commercializing our drug candidates.

Our commercial success depends in part on our avoiding infringement of the patents and other intellectual property rights of third parties. There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including litigation in the U.S. courts, inter partes review, post grant review, interference and ex parte reexamination proceedings before the USPTO or oppositions and other comparable proceedings in non-U.S. jurisdictions. Numerous issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing drug candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our drug candidates or manufacturing processes may give rise to claims of infringement of the patent rights of others.

Third parties may assert that we are employing their proprietary technology without authorization. There may be third-party patents of which we are currently unaware with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our drug candidates. Because patent applications can take many years to issue, patent applications that are currently pending may later result in issued patents that our drug candidates may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies that are first publicized or commercialized after the filing date of those patents infringes upon them. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our drug candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to prevent us from commercializing such drug candidate unless we obtain a license under the applicable patents, or until such patents expire or are finally determined to be held invalid or unenforceable. Similarly, if any third-party patent is held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use, including combination therapy or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize the applicable drug candidate unless we obtain a license, limit our uses, or until such patent expires or is finally determined to be held invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all.

Third parties who bring successful claims against us for infringement of their intellectual property rights may obtain injunctive or other equitable relief, which could prevent us from developing and commercializing one or more of our drug candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of management and employee resources from our business. In the event of a successful claim of infringement or misappropriation against us, we may have to pay substantial damages, including treble damages and attorneys’ fees in the case of willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing drug candidates, which may be impossible or require substantial time and monetary expenditure and undertaking additional preclinical studies, clinical trials or regulatory review. In the event of an adverse result in any such litigation, or even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our drug candidates. We cannot predict whether any required license would be available on commercially reasonable terms, or at all, and we may fail to obtain any of these licenses on commercially reasonable terms, if at all. In the event that we are unable to obtain such a license, we would be unable to further develop and commercialize one or more of our drug candidates, which could harm our business significantly. We may also elect to enter into license agreements in order to settle patent infringement claims or to resolve disputes prior to litigation and any such license agreements may require us to pay royalties and other fees that could significantly harm our business.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our technical personnel, management personnel, or both from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the market price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

In particular, on August 13, 2018, APS and APD, our wholly-owned subsidiaries, filed a complaint for declaratory judgment against Par Pharmaceuticals, Inc., Par Sterile Products, LLC and Endo Par Innovation Company, LLC (together, “Par”) in the United States District Court for the Western District of New York (the “Court”), seeking a declaratory judgment from the Court that our compounded vasopressin drug products in ready-to-use form do not infringe on patents that Par has with respect to its Vasostrict® product and that Par’s patents are invalid. On October 22, 2018, Par filed a motion to dismiss the complaint on the basis that the Court does not have subject matter jurisdiction. On July 9, 2019, the Court issued a decision dismissing the complaint for lack of subject matter jurisdiction, finding that there was no actual controversy between the parties at the time the lawsuit was filed. We do not intend to appeal this decision. Par has not claimed any infringement of its patents, but it could do so by commencing a new lawsuit against us. If such an infringement lawsuit were brought and the court ruled for Par, we could be enjoined from further production of compounded vasopressin within in the United States and sale of compounded vasopressin in or from the United States and for payment of damages to Par for U.S. manufacture or sale of compounded vasopressin that has already taken place.

In addition, on August 13, 2018, APS and APD filed a motion to intervene and seek the dismissal of Par Sterile Products, LLC’s and Endo Par Innovation Company, LLC’s complaint against the FDA and certain governmental officials in the DC Court. Our motion to intervene was granted. These two Par entities have sought declaratory and injunctive relief, including a preliminary injunction, against FDA and certain governmental officials that: (i) vasopressin be delisted from Category 1 of FDA’s list of bulk drug substances under evaluation pursuant to Section 503B of the FDCA, (ii) the expansion of FDA’s enforcement discretion to Category 1 substances, be enjoined; and (iii) that FDA be enjoined from authorizing the compounding of vasopressin under Section 503B of the FDCA. We and FDA filed motions for judgment on the pleadings. On February 7, 2019, before resolving the above pending motions, the DC Court stayed the case until the earlier of: (i) March 15, 2019; (ii) FDA publishes in the Federal Register a final determination about whether to include vasopressin on the clinical need list; or (iii) Par notify the Parties and the Court of a substantial change in circumstances necessitating a decision on Plaintiffs’ Motion for Preliminary Injunction. On March 4, 2019, FDA published in the Federal Register its final decision not to include vasopressin on the list of bulk drug substances for which there is a clinical need. On the same day, we (Athenex, Inc., APS, and APD) filed a complaint in the DC Court against FDA seeking to vacate its final decision. Par Sterile Products, LLC and Endo Par Innovation Company, LLC joined this case as intervenors.

On March 11, 2019, the DC Court extended the stay of Par’s lawsuit against FDA until resolution of the motions for summary judgment in this newer related case.

Athenex produced and distributed compounded vasopressin during the period that the case was pending before the DC District Court and prior to its decision.

If our products conflict with the intellectual property rights of third parties, we may incur substantial liabilities and we may be unable to commercialize products in a profitable manner or at all.

We seek to launch generic pharmaceutical products either where patent protection or other regulatory exclusivity of equivalent branded products has expired, where patents have been declared invalid or where products do not infringe the patents of others. However, at times, we may seek approval to market generic products before the expiration of patents relating to the branded versions of those products, based upon our belief that such patents are invalid or otherwise unenforceable or would not be infringed by our products. Our success depends in part on our ability to operate without infringing the patents and proprietary rights of third parties. The manufacture, use and sale of generic versions of products has been subject to substantial litigation in the pharmaceutical industry. These lawsuits relate to the validity and infringement of patents or proprietary rights of third parties. If our products were found to be infringing the intellectual property rights of a third-party, we could be required to cease selling the infringing products, causing us to lose future sales revenue from such products and face substantial liabilities for patent infringement, in the form of payment for the innovator’s lost profits or a royalty on our sales of the infringing product. These damages may be significant and could materially adversely affect our business. Any litigation, regardless of the merits or eventual outcome, would be costly and time consuming and we could incur significant costs and/or a significant reduction in revenue in defending the action and from the resulting delays in manufacturing, marketing or selling any of our products subject to such claims.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for noncompliance with these requirements.

The USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. Periodic maintenance fees on any issued patent are due to be paid to the USPTO and other patent agencies in several stages over the lifetime of the patent. Although an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment of a patent application or lapse of a patent include failure to respond to official actions within prescribed time limits, non-payment of fees, and failure to properly legalize and submit formal documents. In any such event, our competitors might be able to enter the market, which would have a material adverse effect on our business.

The terms of our patents may not be sufficient to effectively protect our drug candidates and business.

In most countries in which we file patent applications, including the U.S., the term of an issued patent is twenty years from the earliest claimed filing date of a non-provisional patent application in the applicable country. With respect to any issued patents in the U.S., we may be entitled to obtain a patent term extension or extend the patent expiration date provided we meet the applicable requirements for obtaining such patent term extensions. Although such extensions may be available, the life of a patent and the protection it affords is by definition limited. Even if patents covering our drug candidates are obtained, we may be open to competition from other companies as well as generic medications once the patent life has expired for a drug. If patents are issued on our currently pending patent applications, the resulting patents will be expected to expire on dates ranging approximately from 2024 to 2040, excluding any potential patent term extension or adjustment. Upon the expiration of our issued patents, we will not be able to assert such patent rights against potential competitors and our business and results of operations may be adversely affected.

In addition, the rights granted under any issued patents may not provide us with protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies. For these reasons, we may have competition for our technologies, platforms and product candidates. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that a related patent may expire before any particular product candidate can be commercialized or that such patent will remain in force for only a short period following commercialization, thereby reducing any significant advantage of the patent.

If we do not obtain additional protection under the Hatch-Waxman Amendments and similar legislation in other countries extending the terms of our patents, if issued, relating to our drug candidates, our business may be materially harmed.

Depending upon the timing, duration and specifics of FDA regulatory approval for our drug candidates, one or more of our U.S. patents, if issued, may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent term extension of up to five years as compensation for patent term lost during drug development and the FDA regulatory review process. Patent term extensions, however, cannot extend the remaining term of a patent beyond a total of fourteen years from the date of drug approval by the FDA, and only one patent can be extended for a particular drug.

The application for patent term extension is subject to approval by the USPTO, in conjunction with the FDA. We may not be granted an extension due to, for example, failure to apply within applicable deadlines, failure to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain a patent term extension for a given patent or the term of any such extension is less than we request, the period during which we will have the right to exclusively market our drug will be shortened and our competitors may obtain earlier approval of competing drugs. As a result, our ability to generate revenues could be materially adversely affected.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our drug candidates.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patent rights. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity, and is therefore costly, time-consuming, and inherently uncertain. In addition, the U.S. has recently enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents once obtained. Depending on decisions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. For example, in Assoc. for Molecular Pathology v. Myriad Genetics, Inc., the U.S. Supreme Court held that certain claims to naturally-occurring substances are not patentable. Although we do not believe that our issued patents or any patents that may issue from our pending patent applications directed to our drug candidates if issued in their currently pending forms, as well as patent rights licensed by us, will be found invalid based on this decision, we cannot predict how future decisions by the courts, the U.S. Congress or the USPTO may impact the value of our patent rights. There could be similar changes in the laws of foreign jurisdictions that may impact the value of our patent or our other intellectual property rights.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. We may also be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

In addition to our issued patents and pending patent applications, we rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position and to protect our drug candidates. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties that have access to them, such as our employees, corporate collaborators, outside scientific collaborators, sponsored researchers, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants. These agreements provide that all confidential information concerning our business or financial affairs developed or made known to the individual during the course of the individual’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions conceived by the individual, and which are related to our current or planned business or research and development or made during normal working hours, on our premises or using our equipment or proprietary information, are our exclusive property. In many cases our confidentiality and other agreements with consultants, outside scientific collaborators, sponsored researchers and other advisors require them to assign to us or grant us licenses to inventions they invent as a result of the work or services they render under such agreements or grant us an option to negotiate a license to use such inventions. However, any of these parties may breach such agreements and disclose our proprietary information, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete with us and our competitive position would be harmed.

Furthermore, many of our employees, including our senior management, were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Some of these employees, including each member of our senior management, executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee’s former employer. We are not aware of any threatened or pending claims related to these matters or concerning the agreements with our senior management, but litigation may be necessary in the future to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

In addition, while we typically require our employees, consultants and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own, which may result in claims by or against us related to the ownership of such intellectual property. If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to our management and scientific personnel. Further, to the extent that our employees, contractors, consultants, collaborators and advisors use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

We also seek to preserve the integrity and confidentiality of our proprietary technology and processes by maintaining physical security of our premises and physical and electronic security of our information technology systems. Although we have confidence in the security of our systems, security measures may be breached, and we may not have adequate remedies for any such breach.

We may not be successful in obtaining or maintaining necessary rights for our development pipeline through acquisitions and in-licenses.

Because our programs may involve additional drug candidates that require the use of proprietary rights held by third parties, the growth of our business may depend in part on our ability to acquire and maintain licenses or other rights to use these proprietary rights. We may be unable to acquire or in-license any compositions, methods of use, or other third-party intellectual property rights from third parties that we identify. The licensing and acquisition of third-party intellectual property rights is a competitive area, and a number of established companies are also pursuing strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities.

In addition, companies that perceive us to be a competitor may be unwilling to assign or license intellectual property rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain rights to required third-party intellectual property rights, our business, financial condition and prospects for growth could suffer.

If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could be required to pay monetary damages or could lose license rights that are important to our business.

We have entered into license agreements with third parties providing us with rights under various third-party patents and patent applications, including the rights to prosecute patent applications and to enforce patents. Certain of these license agreements impose and, for a variety of purposes, we may enter into additional licensing and funding arrangements with third parties that also may impose diligence, development or commercialization timelines and milestone payment, royalty, insurance and other obligations on us. Certain of these license agreements provide us with the exclusive right to practice technologies in major markets including North America, South America, the EU, Australia, New Zealand, Eastern Europe, China, Taiwan, Hong Kong, Macau and parts of Southeast Asia, although the right to practice the technologies and any inventions arising out of such technologies outside of these territories may be reserved to the licensing company. In addition, under certain of our existing licensing agreements, we are obligated to pay royalties on net product sales of our drug candidates once commercialized, pay a percentage of sublicensing revenues, make other specified payments relating to our drug candidates or pay license maintenance and other fees. We also have diligence and clinical development obligations under certain of these agreements that we are required to satisfy. If we fail to comply with our obligations under our current or future license agreements, our counterparties may have the right to terminate these agreements, in which event we might not be able to develop, manufacture or market any drug or drug candidate that is covered by the licenses or we may face claims for monetary damages or other penalties under these agreements. Such an occurrence could diminish the value of these products and our company. Termination of the licenses provided in these agreements or reduction or elimination of our rights under these agreements may result in our having to negotiate new or reinstated agreements with less favorable terms or cause us to lose our rights under these agreements, including our rights to important intellectual property or technology.

In particular, our ability to stop third parties from making, using, selling, offering to sell or importing any of our patented inventions, either directly or indirectly, will depend in part on our success in obtaining, defending, and enforcing patent claims that cover our technology, inventions and improvements. With respect to both licensed and company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future will be commercially useful in protecting our platforms and product candidates and the methods used to manufacture those platforms and product candidates. Our issued patents and those that may issue in the future may be challenged, invalidated or circumvented, which could limit our ability to stop competitors from marketing related platforms or product candidates or limit the length of the term of patent protection that we may have for our technologies, platforms and product candidates.

If our licensing and sublicensing activities result in non-compliance with our licensing agreements, our business relationships with our licensing partners may suffer and we may be required to pay monetary damages or rescind or amend existing agreements which are important to our business.

We have entered into agreements with third parties under which we have granted licenses to use certain of our patents and patent applications, including the rights to develop, seek regulatory approval for and sell products using our KX-01 and KX-02 products. We have also entered into similar agreements sublicensing the intellectual property for the Orascovery platform, which we have licensed from Hanmi Pharmaceutical Co., Ltd. (“Hanmi”). We have granted exclusive patent rights to certain of these partners and have granted them certain additional rights with respect to the intellectual property we have licensed to them. From time to time we may engage in other licensing transactions in which we acquire licenses to certain intellectual property or sublicense intellectual property rights. If we fail to comply with or are found to have violated the terms of any of our licenses, we may be required to rescind or amend our license agreements or pay damages to license counterparties or other rightsholders. This may also negatively impact our relationships with our licensing and sublicensing partners for our candidate platforms.

Related to Our Reliance on Third Parties

We depend on our agreements with Hanmi to provide rights to the intellectual property relating to certain of our lead product candidates. Any termination or loss of significant rights under those agreements would adversely affect our development or commercialization of our lead product candidates.

We have licensed the intellectual property rights related to encequidar, an integral part of our current product candidates, from Hanmi pursuant to two license agreements. If, for any reason, our license agreements are terminated or we otherwise lose those rights, it would adversely affect our business. Our license agreements with Hanmi impose on us obligations relating to exclusivity, territorial rights, development, commercialization, funding, payment, diligence, sublicensing, insurance, intellectual property protection and other matters. If we breach any material obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages to Hanmi, and Hanmi may have the right to terminate our license, which could result in us being unable to develop, manufacture and sell our product candidates that incorporate encequidar.

In addition, under our 2013 license agreement with Hanmi, we have granted Hanmi a one-time right of first negotiation that, at Hanmi’s discretion, requires us to negotiate in good faith the sale of our rights in oral paclitaxel and oral irinotecan under such agreement to Hanmi at a purchase price determined by an internationally-recognized investment banking firm with an office in Hong Kong at any time prior to the earlier of (i) our first commercial sale of products using such technology or (ii) receipt by Hanmi of written notice from our company of the sublicense of the rights in an applicable product to a third party. If Hanmi exercises this right of first negotiation and we reach an agreement to sell our rights under that licensing agreement, our ability to continue to develop certain of our product candidates would be significantly impaired and would adversely affect our business and results of operations.

Each of our license agreements with Hanmi expires on the earlier of (i) expiration of the last of Hanmi’s patent rights licensed under the agreement or (ii) invalidation of Hanmi’s patent rights which are the subject of the agreement, provided that the term will automatically be extended for consecutive one year periods unless either party gives notice to the other at least ninety days prior to expiration of the patent rights licensed under the agreement or before the then current annual expiration date of the agreement. The patent rights licensed to us under the agreements with Hanmi have expiry dates ranging from 2023 to 2033, unless the terms of such licensed patents are extended in accordance with applicable laws and regulations. Subject to certain conditions, Hanmi may also terminate the license agreements if we fail to comply with certain development milestones set out in each of the agreements. The agreements also contain customary termination rights for either party, such as in the event of a breach of the agreement or the initiation of bankruptcy proceedings by the other party or by mutual agreement.

We may rely on third parties to conduct our preclinical studies and clinical trials. If these third parties do not successfully carry out their contractual duties, meet expected deadlines, perform satisfactorily or operate in compliance with laws and regulations, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business could be substantially harmed.

We have relied upon and may, in the future, rely upon third-party CROs to monitor and manage data for our ongoing preclinical and clinical programs. We rely on these parties for execution of our preclinical studies and clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, and regulatory requirements and scientific standards, and our reliance on the CROs does not relieve us of our regulatory responsibilities. In addition, if we complete the acquisition of CIDAL as intended, our preclinical and clinical programs will largely be performed within the Company and we will be responsible for conducting clinical trials and complying with applicable laws and regulations.

We and our CROs are required to comply with GCPs, which are regulations and guidelines enforced by the FDA, NMPA and other regulatory authorities for all of our drugs in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of our CROs fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, NMPA or regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

If any of our relationships with these third-party CROs terminate, or we are unable to successfully complete the acquisition of CIDAL and integrate their business into ours, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. In addition, our CROs are not our employees, and except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time and resources to our ongoing clinical, non-clinical and preclinical programs. In the event that any of our foreign CROs are impacted by political, social or financial instability, they may be unable to maintain production capacity or compliance with regulatory requirements. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements, environmental, health and safety laws and regulations, or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our drug candidates. As a result, our results of operations and the commercial prospects for our drug candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

Our total revenue is highly dependent on a limited number of API customers and pharmaceutical wholesalers, and the loss of, or any significant decrease in business from, any one or more of our major API customers or pharmaceutical wholesalers could adversely affect our financial condition and results of operations.

We have derived a significant portion of our revenue from a limited number of customers, as is typical in the pharmaceutical industry. During the year ended December 31, 2016, prior to the launch of our specialty products, we generated 62% of our total revenue from our two largest API customers, Intas Pharmaceuticals and Ebewe Pharmaceuticals. During the year ended December 31, 2017, we generated 28% of our total revenue from those API customers and generated 28% of our total revenue from the three largest wholesalers in the U.S. market, Amerisource, Cardinal Health, and McKesson (15%, 7%, and 6%, respectively). During the year ended December 31, 2018, we generated 10% of our total revenue from those API customers and generated 30% of our total revenue from the three largest wholesalers in the U.S. market, Amerisource, Cardinal Health, and McKesson (12%, 9%, and 9%, respectively). During the period ended June 30, 2019, we generated 10% of our total revenue from those API customers and generated 50% of our total revenue from the three largest wholesalers in the U.S. market, Amerisource, Cardinal Health, and McKesson (21%, 15%, and 14%, respectively).

There are a number of factors that could cause us to lose major API customers. We do not enter into long-term sales contracts with customers but sell API to them based on short-term purchase orders. Accordingly, these customers may choose to use other suppliers with little or no notice, based upon considerations of price, quality, shipping time, competitive or other reasons. In addition, our API customers use the API to manufacture drugs, and they are subject to regulation and oversight by the FDA and other relevant regulatory agencies. If for any reason, any such customer violates an FDA regulation that results in their being prohibited from manufacturing drugs, they would no longer purchase API from us. Such sanctions or regulatory action against drug manufacturers could happen without notice, and our revenue stream could be adversely affected without notice. Because operations at our plant in Chongqing, China are currently suspended, we may not be able to manufacture the API our customers require in the future. If any of our customers finds its own alternate supplier of API, we may lose our API customers and be unable to generate revenue from API sales.

If we are unable to maintain our business relationships with these major API customers and pharmaceutical wholesalers on commercially acceptable terms, it could have a material adverse effect on our financial condition and results of operations. Even if we are able to maintain our relationships with customers, a change in the mix of products those customers purchase and which we are able to produce may affect our gross margin and results of operations.

Additionally, Polymed, our wholly owned subsidiary, sells API to third parties for use in those third parties’ products, which may be manufactured in cGMP facilities. In the event Polymed’s customers fail to remain in compliance with cGMP regulations, their operations may be adversely impacted, causing them to cancel or cease API orders from Polymed. Any decrease in orders by Polymed’s customers may impact Polymed’s revenue and, as a result, our overall financial condition.

If our Global Supply Chain Platform is insufficient, we may rely on third parties to manufacture at least a portion of our drug candidate supplies, and for at least a portion of the manufacturing process of our drug candidates, if approved. Our business could be harmed if those third parties fail to provide us with sufficient quantities of product or fail to do so at acceptable quality levels or prices.

We partially rely on outside vendors to manufacture supplies and process our drug candidates. We have not yet begun to manufacture or process our drug candidates on a commercial scale and may not be able to do so for any of our drug candidates.

We have limited experience in managing the manufacturing process, and our process may be more difficult or expensive than the approaches currently in use.

Although we do intend to further develop our manufacturing facilities, and those leased to us under our public-private partnerships, we may also use third parties as part of our manufacturing process. Our reliance on third-party manufacturers may expose us to the following risks:

	•	we may be unable to identify manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and the FDA, NMPA or other regulatory authorities must approve any manufacturers. This approval would require new testing and cGMP-compliance inspections by FDA, NMPA or other regulatory authorities. In addition, a new manufacturer would have to be educated in, or develop substantially equivalent processes for, production of our drugs;
	•	our manufacturers may have little or no experience with manufacturing our drug candidates and, therefore, may experience quality issues or require a significant amount of support from us in order to implement and maintain the infrastructure and processes required to manufacture our drug candidates;
	•	our third-party manufacturers might be unable to timely manufacture our drug or produce the quantity and quality required to meet our clinical and commercial needs, if any;
	•	contract manufacturers may not be able to execute our manufacturing procedures and other logistical support requirements appropriately;
	•	our future contract manufacturers may not perform as agreed, may not devote sufficient resources to our drugs, or may not remain in the contract manufacturing business for the time required to supply our clinical trials or to successfully produce, store and distribute our drugs;
	•	we may not own, or may have to share, the intellectual property rights to any improvements made by our third-party manufacturers in the manufacturing process for our drugs;
	•	our third-party manufacturers could breach or terminate their agreement with us;
	•	raw materials and components used in the manufacturing process, particularly those for which we have no other source or supplier, may not be available or may not be suitable or acceptable for use due to material or component defects;
	•	our contract manufacturers and critical reagent suppliers may be subject to inclement weather, as well as natural or man-made disasters and
	•	our contract manufacturers may have unacceptable or inconsistent product quality success rates and yields.

Each of these risks could delay or prevent the completion of our clinical trials or the approval of any of our drug candidates by the FDA, NMPA or other regulatory authorities, result in higher costs or adversely impact commercialization of our drug candidates. In addition, we will rely on third parties to perform certain specification tests on our drug candidates prior to delivery to patients. If these tests are not conducted appropriately and test data are not reliable, patients could be put at risk of serious harm and the FDA, NMPA or other regulatory authorities could place significant restrictions on our company until deficiencies are remedied.

The manufacture of drug and biological products is complex and requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls.

Currently, raw materials used in our manufacturing activities, including the pacific yew used in many of the API products we manufacture, are supplied by multiple suppliers. We have agreements for the supply of such raw materials with manufacturers or suppliers that we believe have sufficient capacity to meet our demands. In addition, we believe that adequate alternative sources for such supplies exist. However, there is a risk that, if supplies are interrupted, it would materially harm our business.

Manufacturers of drug and biological products often encounter difficulties in production, particularly in scaling up or out, validating the production process, and assuring high reliability of the manufacturing process (including the absence of contamination). These problems include logistics and shipping, difficulties with production costs and yields, quality control, including stability of the product, product testing, operator error, availability of qualified personnel, as well as compliance with strictly enforced federal, state and non-U.S. regulations. Furthermore, if contaminants are discovered in our supply of our drug candidates or in the manufacturing facilities, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. We cannot assure you that any stability failures or other issues relating to the manufacture of our drug candidates will not occur in the future. Additionally, our manufacturers may experience manufacturing difficulties due to resource constraints or as a result of labor disputes or unstable political environments. If our manufacturers were to encounter any of these difficulties, or otherwise fail to comply with their contractual obligations, our ability to provide our drug candidate to patients in clinical trials would be jeopardized. Any delay or interruption in the supply of clinical trial supplies could delay the completion of clinical trials, increase the costs associated with maintaining clinical trial programs and, depending upon the period of delay, require us to begin new clinical trials at additional expense or terminate clinical trials completely.

If third-party manufacturers fail to comply with pharmaceutical manufacturing regulations, our financial results and financial condition will be adversely affected.

Before a third party can begin commercial manufacture of our drug candidates and potential drugs, contract manufacturers are subject to regulatory inspections of their manufacturing facilities, processes and quality systems. Due to the complexity of the processes used to manufacture drug and biological products and our drug candidates, any potential third-party manufacturer may be unable to initially pass federal, state or international regulatory inspections in a cost effective manner in order for us to obtain regulatory approval of our drug candidates. If our contract manufacturers do not pass their inspections by the FDA, NMPA or other regulatory authorities, our commercial supply of drug product or substance will be significantly delayed and may result in significant additional costs, including the delay or denial of any marketing application for our drug candidates. In addition, drug and biological manufacturing facilities are continuously subject to inspection by the FDA, NMPA and other regulatory authorities, before and after drug approval, and must comply with cGMPs. Our contract manufacturers may encounter difficulties in achieving quality control and quality assurance and may experience shortages in qualified personnel. In addition, contract manufacturers’ failure to achieve and maintain high manufacturing standards in accordance with applicable regulatory requirements, or the incidence of manufacturing errors, could result in patient injury, product liability claims, product shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could seriously harm our business, reputation or corporate image. If a third-party manufacturer with whom we contract is unable to comply with manufacturing regulations, we may also be subject to fines, unanticipated compliance expenses, recall or seizure of our drugs, product liability claims, total or partial suspension of production and/or enforcement actions, including injunctions and criminal or civil prosecution. These possible sanctions could materially adversely affect our financial results and financial condition.

Furthermore, changes in the manufacturing process or procedure, including a change in the location where the product is manufactured or a change of a third-party manufacturer, could require prior review by the FDA, NMPA or other regulatory authorities and/or approval of the manufacturing process and procedures in accordance with the FDA or NMPA’s regulations, or comparable requirements. This review may be costly and time consuming and could delay or prevent the launch of a product. The new facility will also be subject to pre-approval inspection. In addition, we have to demonstrate that the product made at the new facility is equivalent to the product made at the former facility by physical and chemical methods, which are costly and time consuming. It is also possible that the FDA, NMPA or other regulatory authorities may require clinical testing as a way to prove equivalency, which would result in additional costs and delay.

We have entered into collaborations and may form or seek collaborations or strategic alliances or enter into additional licensing arrangements in the future, and we may not realize the benefits of such alliances or licensing arrangements.

We have partnered with companies such as Hanmi, Almirall S.A., XLifeSc and Gland and may form or seek strategic alliances, create joint ventures or collaborations, or enter into additional licensing arrangements with third parties that we believe will complement or augment our development and commercialization efforts with respect to our drug candidates and any future drug candidates that we may develop. Any of these relationships may require us to incur non-recurring and other charges, increase our near

and long-term expenditures, issue securities that dilute our existing stockholders, or disrupt our management and business. For example, pursuant to our agreement with Almirall, if Almirall does not find our Phase 3 results of KX2-391 satisfactory, it has the right to request repayment of the milestone payment we received in the second quarter of 2019, and our agreement may be terminated. If this license agreement is terminated, we will have the right to pursue commercialization of KX2-391 on our own, which would require us to further invest in the product and fund its commercialization, if approved.

In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our drug candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our drug candidates as having the requisite potential to demonstrate safety and efficacy. If and when we collaborate with a third party for development and commercialization of a drug candidate, we can expect to relinquish some or all of the control over the future success of that drug candidate to the third party.

Further, collaborations involving our drug candidates are subject to numerous risks, which may include the following:

	•	collaborators have significant discretion in determining the efforts and resources that they will apply to a collaboration;
	•	collaborators may not pursue development and commercialization of our drug candidates or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes in their strategic focus due to the acquisition of competitive drugs, availability of funding or other external factors, such as a business combination that diverts resources or creates competing priorities;
	•	collaborators may delay clinical trials, provide insufficient funding for a clinical trial, stop a clinical trial, abandon a drug candidate, repeat or conduct new clinical trials or require a new formulation of a drug candidate for clinical testing;
	•	collaborators could independently develop, or develop with third parties, drugs that compete directly or indirectly with our drugs or drug candidates;
	•	a collaborator with marketing and distribution rights to one or more drugs may not commit sufficient resources to their marketing and distribution;
	•	collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;
	•	disputes may arise between us and a collaborator that cause the delay or termination of the research, development or commercialization of our drug candidates, or that result in costly litigation or arbitration that diverts management attention and resources;
	•	collaborations may be terminated and, if terminated, may result in a need for additional capital to pursue further development or commercialization of the applicable drug candidates; and
	•	collaborators may own or co-own intellectual property covering our drugs that results from our collaborating with them, and in such cases, we would not have the exclusive right to commercialize such intellectual property.

As a result, if we enter into collaboration agreements and strategic partnerships or license our drugs, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or specific net income that justifies such transaction. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail the development of a drug candidate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to further develop our drug candidates or bring them to market and generate product sales revenue, which would harm our business prospects, financial condition and results of operations.

We have engaged and will continue to rely on a single vendor to manage our order to cash cycle and our distribution activities in the U.S., and the loss or disruption of service from this vendor could adversely affect our operations and financial condition.

Our U.S. customer management, order processing, invoicing, cash application, chargeback and rebate processing and distribution and logistics activities are managed by Eversana Life Science Services (“Eversana”), a managed services provider with a focus on life sciences companies. If we were to lose the availability of Eversana’s services due to a dispute, termination of or inability to renew the contract, or other factors such as fire, natural disaster or other disruption, such loss could have a material adverse effect on our operations. Although multiple providers of such services exist, there can be no assurance that we could secure another source to handle these transactions on acceptable terms or otherwise to our specifications in the event of a disruption of services at operational centers.

Risks Related to Our Industry, Business and Operation

We are dependent on our key personnel, and if we are not successful in attracting and retaining qualified personnel, we may not be able to successfully implement our business strategy. Additionally, certain members of our leadership may engage in other business ventures that may have interests in conflict with ours.

We are highly dependent on Dr. Lau, our Chief Executive Officer, Dr. Kwan, our Chief Medical Officer and the other principal members of our management and scientific teams. We do not maintain “key person” insurance for any of our executives or other employees. The loss of the services of any of these persons could impede the achievement of our research, development and commercialization objectives.

To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided stock option grants that vest over time. The value to employees of these equity grants that vest over time may be significantly affected by changes in the price of our common stock that are beyond our control and may at any time be insufficient to counteract more lucrative offers from other companies. Although we have employment agreements with our key employees, any of our employees could leave our employment at any time, with or without notice.

Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel or consultants will also be critical to our success. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our discovery and preclinical development and commercialization strategy. The loss of the services of our executive officers or other key employees and consultants could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy.

Furthermore, replacing executive officers and key employees or consultants may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel or consultants on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel.

We may choose to hire part-time employees or use consultants. As a result, certain of our employees, officers, directors and consultants may not devote all of their time to our business, and may from time to time serve as officers, directors and consultants of other companies. These other companies may have interests in conflict with ours. For instance, Dr. Johnson Lau, who serves as our Chief Executive Officer and Chairman, Dr. Manson Fok, who serves on our board of directors, are also directors of Avalon Global Holdings Limited, or Avalon, a stockholder of ours. Dr. Lau also serves as the Chief Executive Officer of Axis, a joint venture that we majority own.

We also face competition for the hiring of scientific and clinical personnel from universities and research institutions. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.

We are substantially dependent on our public-private partnerships and if we or our counterparties fail to meet the obligations of those agreements and we lose the benefits of those partnerships, it would materially impact our development, operations and prospects.

Our long-term public-private partnerships with governments and government agencies, including in certain emerging markets, include agreements to build and/or maintain manufacturing facilities for us. For example, we entered into an agreement with FSMC, whereby FSMC agreed to fund the costs of construction of a new manufacturing facility in Dunkirk, New York. FSMC is responsible for the costs of construction and of all equipment for the facility, up to an amount not to exceed $200 million plus any

amounts not used under the prior $25 million grant to construct our North American headquarters and formulation lab in Buffalo, New York, and shall retain ownership of the Dunkirk facility and the equipment. To the extent the costs of constructing the Dunkirk facility exceed approximately $206 million, we will be responsible for those costs. We are entitled to lease the facility and all equipment at a rate of $1.00 per year for an initial 10-year term, and for the same rate if we elect to extend the lease for an additional 10-year term. We are responsible for all operating costs and expenses for the facility. In exchange, we have committed to spending $1.52 billion on operational expenses in the Dunkirk facility in our first 10-year term in the facility, and an additional $1.5 billion on operational expenses if we elect to extend the lease for a second 10-year term. We have also committed to hiring 450 permanent employees within the first 5 years at the Dunkirk facility. In addition, in July 2017, we entered into a 20-year payment in-lieu of tax agreement with the CCIDA for the construction of our Dunkirk facility, valued at approximately $9.1 million. We have also entered into similar arrangements with FSMC relating to our headquarters, and Chongqing Maliu Riverside Development & Investment Co., Ltd. relating to a plant in Chongqing, China, under which we have committed to achieving certain operating, revenue and tax generation milestones. If we are unable to comply with our obligations under these arrangements, including the milestones we have committed to achieve, we may lose access to the properties covered by such arrangements which could disrupt our operations and manufacturing activities, cause us to divert resources to finding alternative facilities, which would not have any subsidies, and would have a significant impact on our operations and financial performance. We may also be subject to lawsuits or claims for damages against us if we are unable to comply with our obligations under these arrangements. For example, our potential liability in connection with a failure to comply with the New York State partnership agreements could be as high as $225 million, depending on the amount of funding ESD had contributed to the Dunkirk project at the time of the claim.

Furthermore, there is no guarantee that the counterparties to our public-private partnerships will comply with the terms of the agreements, including that their ability to fund their capital commitments under the agreements may be subject to their ability to raise additional capital and that construction timetables may not be met, nor is there guarantee that the successors to such counterparties will continue to comply with terms of the agreements, regardless of existence of such government stipulations as a guideline released on November 4, 2016 by the State Council of China, which provides that, among others governments and relevant departments at all levels shall strictly keep policy commitments lawfully made to society and administrative counterparties, shall carefully perform all the contracts lawfully entered into with investment subjects in activities like attraction of investment and public-private partnership, shall not breach contracts with such excuses as government transition and replacement of leaders, and shall bear legal and economic liability in event of their infringements and contract breaches. If our public-private partnership counterparties or their successors fail to comply with their obligations under these arrangements, our development programs and prospects will be materially adversely affected. Public-private partnerships are also subject to risks associated with government and government agency counterparties, including risks related to government relations compliance, sovereign immunity, shifts in the political environment, changing economic and legal conditions and social dynamics.

We will need to continue to increase the size and capabilities of our organization, and we may experience difficulties in managing our growth.

As of June 30, 2019, we had 593 employees and consultants and most of our employees are full-time. As our development and commercialization plans and strategies develop, and as we continue to operate as a public company, we must add a significant number of additional managerial, operational, sales, marketing, financial and other personnel. Future growth will impose significant added responsibilities on members of management, including:

	•	identifying, recruiting, integrating, maintaining and motivating additional employees;
	•	managing our internal development efforts effectively, including the clinical and FDA or other comparable authority review process for our drug candidates, while complying with our contractual obligations to contractors and other third parties; and
	•	improving our operational, financial and management controls, reporting systems and procedures.

Our future financial performance and our ability to commercialize our drug candidates will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities. In addition, we expect to incur additional costs in hiring, training and retaining such additional personnel.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize our drug candidates and, accordingly, may not achieve our research, development and commercialization goals.

If we fail to maintain effective internal control over financial reporting, we may not be able to accurately report our consolidated financial results.

We cannot assure you that there will not be material weaknesses and significant deficiencies that our independent registered public accounting firm or we will identify in the future. Under standards established by the Public Company Accounting Oversight Board, a deficiency in internal control over financial reporting exists when the design or operation of a control does not allow management or personnel, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis. A material weakness is a deficiency or combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected and corrected on a timely basis. As a public company, we also need to establish and maintain effective disclosure and financial controls and make changes in our corporate governance practices including our board and committee practices. If we identify such issues or if we are unable to produce accurate and timely financial statements, our stock price may be adversely affected, and we may be unable to maintain compliance with applicable listing requirements.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

Upon completion of our initial public offering, we became subject to the periodic reporting requirements of the Exchange Act. Our disclosure controls and procedures are designed to reasonably assure that information required to be disclosed by us in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.

We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected, which would cause us to be unable to produce accurate financial statements and may adversely affect our business.

Our employees, independent contractors, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk of fraud, misconduct or other illegal activity by our employees, independent contractors, consultants, commercial partners and vendors. Misconduct by these parties could include intentional, reckless and negligent conduct that fails to: comply with the laws of the FDA and other similar non-U.S. regulatory authorities; provide true, complete and accurate information to the FDA and other similar non-U.S. regulatory authorities; comply with manufacturing standards we have established; comply with healthcare fraud and abuse and privacy laws in the U.S. and similar non-U.S. fraudulent misconduct laws; or report financial information or data accurately or to disclose unauthorized activities to us. If we obtain FDA approval of any of our drug candidates and begin commercializing those drugs in the U.S., our potential exposure under U.S. laws will increase significantly and our costs associated with compliance with such laws are also likely to increase. These laws may impact, among other things, our current activities with principal investigators and research patients, as well as proposed and future sales, marketing and education programs. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter misconduct by employees and other parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

We may have conflicts of interest with our affiliates and related parties, and in the past we have engaged in transactions and entered into agreements with affiliates that were not negotiated at arms’ length.

We have engaged, and may in the future engage, in transactions with affiliates and other related parties. These transactions may not have been, and may not be, on terms as favorable to us as they could have been if obtained from non-affiliated persons. While an effort has been made and will continue to be made to obtain services from affiliated persons and other related parties at rates and on terms as favorable as would be charged by others, there will always be an inherent conflict of interest between our interests and those of our affiliates and related parties. Our affiliates may economically benefit from our arrangements with related parties. If we engage in related party transactions on unfavorable terms, our operating results will be negatively impacted.

If we engage in future acquisitions or strategic partnerships, this may increase our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks.

We may evaluate various acquisitions and strategic partnerships, including licensing or acquiring complementary products, intellectual property rights, technologies or businesses. Any potential acquisition or strategic partnership may entail numerous risks, including:

	•	increased operating expenses and cash requirements;
	•	assimilation of operations, intellectual property and products of an acquired company, including difficulties associated with integrating new personnel;
	•	integrating global operations and conducting our business in multiple geographic areas, each with its own legal system and regulations;
	•	the diversion of our management’s attention from our existing product programs and initiatives in pursuing such a strategic merger or acquisition;
	•	retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business relationships;
	•	risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their existing drugs or drug candidates and regulatory approvals and
	•	our inability to generate revenue from acquired technology and/or products sufficient to meet our objectives in undertaking the acquisition or even to offset the associated acquisition and maintenance costs.

In addition, if we undertake acquisitions, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses and acquire intangible assets that could result in significant future amortization expense. Moreover, we may not be able to locate suitable acquisition opportunities and this inability could impair our ability to grow or obtain access to technology or products that may be important to the development of our business.

Our internal computer systems, or those used by our CROs, collaboration partners, third-party service providers or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of cybersecurity measures, our information technology and Internet based systems, including those of our current and future CROs, collaboration partners, third-party service providers and other contractors and consultants, are vulnerable to damage, interruption, or failure from computer viruses, unauthorized access, intrusion, and other cybersecurity incidents. This could result in the exposure of sensitive data including the loss of trade secrets, intellectual property, personal identifiable or sensitive information of employees, customers, partners, clinical trial patients and others, leading to a material disruption of our development programs and our business operations. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we partially rely on our third-party research institution collaborators for research and development of our drug candidates and other third parties for the manufacture of our drug candidates and to conduct clinical trials, and similar cybersecurity incidents relating to their computer systems could also have a material adverse effect on our business. Certain data security breaches must be reported to affected individuals and the government, and in some cases to the media, under provisions of HIPAA, other U.S. federal and state law, and requirements of non-U.S. jurisdictions, and financial penalties may also apply. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of our drug candidates could be delayed.

We are aware of a security breach that occurred in March 2017. That incident occurred when the credentials of an approved consultant were compromised, and the consultant’s credentials were used to access the remote desktop server and active directory server of our wholly-owned subsidiary APS. Upon discovery of the breach, we immediately took steps to void the compromised credentials and reset all credentials having access to APS’ systems. These particular APS information systems are independent of ours and did not contain any drug candidate, clinical trial or patient-specific data. However, information stored on APS’ systems may have been vulnerable during the intrusion. To help mitigate future incidents, we have put in place enhanced security measures required for access by consultants. Notwithstanding such measures, we cannot be certain that no future security breaches will occur or that future breaches will not result in a material disruption of our development programs and our business operations.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

Our operations, and those of our third-party research institution collaborators, CROs, suppliers and other contractors and consultants, could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics, acts of war or terrorism, and other natural or man-made disasters or business interruptions, for which we are predominantly self-insured. In addition, we partially rely on our third-party research collaborators for conducting research and development of our drug candidates, and they may be affected by government shutdowns or withdrawn funding. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. Our ability to obtain clinical supplies of our drug candidates could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster or other business interruption. Damage or extended periods of interruption to our corporate, development or research facilities due to fire, natural disaster, power loss, communications failure, unauthorized entry or other events could cause us to cease or delay development of some or all of our drug candidates. Although we maintain property damage and business interruption insurance coverage on these facilities, our insurance might not cover all losses under such circumstances and our business may be seriously harmed by such delays and interruption.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our drug candidates or our 503B products.

We face an inherent risk of product liability as a result of the clinical testing of our drug candidates and will face an even greater risk if we commercialize any of our clinical candidates. For example, we may be sued if our drug candidates that we plan to manufacture, or our 503B products that we currently manufacture or plan to manufacture cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, as applicable, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the drug, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our drug candidates. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

	•	decreased demand for our drugs;
	•	injury to our reputation;
	•	withdrawal of clinical trial participants and inability to continue clinical trials;
	•	initiation of investigations by regulators;
	•	costs to defend the related litigation;
	•	a diversion of management’s time and our resources;
	•	substantial monetary awards to trial participants or patients;
	•	product recalls, withdrawals or labeling, marketing or promotional restrictions;
	•	loss of revenue;
	•	exhaustion of any available insurance and our capital resources;
	•	the inability to commercialize any drug candidate; and
	•	a decline in the price of our common stock.

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of drugs we develop, alone or with collaborators. Although we currently carry clinical trial insurance, which we believe to be adequate for our current operations, the amount of such insurance coverage may not be adequate now, or in the future, and we may be unable to maintain such insurance, or we may not be able to obtain additional or

replacement insurance at a reasonable cost, if at all. Our insurance policies may also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

Additionally, we may be sued if the products that we commercialize, market or distribute for our partners cause or are perceived to cause injury or are found to be otherwise unsuitable, and may result in:

	•	decreased demand for those products;
	•	damage to our reputation;
	•	costs incurred related to product recalls;
	•	limiting our opportunities to enter into future commercial partnership; and
	•	a decline in the price of our common stock.

We have limited insurance coverage, and any claims beyond our insurance coverage may result in our incurring substantial costs and a diversion of resources.

We maintain property insurance policies covering physical damage to, or loss of, our buildings and their improvements, equipment, office furniture and inventory. We hold employer’s liability insurance generally covering death or work-related injury of employees. We hold public liability insurance covering certain incidents involving third parties that occur on or in the premises of the company. We hold directors and officers liability insurance and business interruption insurance. We do not maintain key-man life insurance on any of our senior management or key personnel. Our insurance coverage may be insufficient to cover any claim for product liability, damage to our fixed assets or employee injuries. Any liability or damage to, or caused by, our facilities or our personnel beyond our insurance coverage may result in our incurring substantial costs and a diversion of resources.

We may increasingly become a target for public scrutiny, including complaints to regulatory agencies, negative media coverage, including social media and malicious reports, all of which could severely damage our reputation and materially and adversely affect our business and prospects.

We focus on the development of drugs used in the treatment of cancers, and such drugs may be the subject of regulatory, watchdog and media scrutiny and coverage, which also the possibility of heightened attention from the public, the media and our participants. In addition, members of our management and board include high-profile public figures who may be the subject of media and public scrutiny and attention. From time to time, these objections or allegations, regardless of their veracity, may result in public protests or negative publicity, which could result in government inquiry or harm our reputation. Corporate transactions we or related parties undertake may also subject us to increased media exposure and public scrutiny. There is no assurance that we would not become a target for public scrutiny in the future or such scrutiny and public exposure would not severely damage our reputation as well as our business and prospects.

In addition, our directors and management have been in the past, and may continue to be, subject to scrutiny by the media and the public regarding their activities in and outside our company, which may result in unverified, inaccurate or misleading information about them being reported by the press. Negative publicity about our directors or management, even if untrue or inaccurate, may harm our reputation.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred net operating losses (“NOLs”) for U.S. federal income tax purposes. Unused NOLs will carry forward to offset future taxable income, if any, until such unused NOLs expire (if ever). NOLs generated after December 31, 2017 are not subject to expiration, but the yearly utilization of such NOLs is limited to 80 percent of taxable income. Under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an ownership change (generally defined as a greater than 50 percentage points change (by value) in the equity ownership of one or more stockholders or groups of stockholders who own at least 5% of a corporation’s stock over any three-year period), the corporation’s ability to use its pre-change NOLs and other pre-change tax attributes to offset its post-change income may be limited. We believe that we have experienced at least one ownership change in the past and may experience one in the future, which may affect our ability to utilize our NOLs. As of December 31, 2018, we had federal NOLs of approximately $253.8 million that could be limited by our past and any future ownership change, which could have an adverse effect on our future results of operations. Similar limitations will apply to our ability to carry forward any unused tax credits to offset future taxable income.

Our business, financial condition and stock price may be adversely affected by volatile global markets and economic conditions.

Our business and operating results could be affected by global economic conditions. When global economic conditions deteriorate or economic uncertainty continues, customers and potential customers may delay or cancellation of plans to purchase our products, governments may reduce healthcare expenditures, and other payors may reduce their reimbursement coverage or reimbursement rates. This uncertainty contributes to volatile global markets generally and may have a negative impact on the market value of our common stock. Our sensitivity to economic cycles and any related fluctuations in the businesses of our customers or potential customers could have a material adverse impact on our business and financial results. Although we are uncertain about the extent to which global financial market disruptions or a slowdown of the U.S. or Chinese economy would impact our business in the long term, there is a risk that our business, results of operations and prospects would be materially and adversely affected by any global economic downturn or the slowdown of the U.S. or Chinese economy.

If our manufacturing facilities are damaged or destroyed or production at such facilities is otherwise interrupted, our business and prospects would be negatively affected.

If our manufacturing facilities or the equipment in them is damaged or destroyed, we may not be able to quickly or inexpensively replace our manufacturing capacity or replace it at all. In the event of a temporary or protracted loss of the facilities or equipment, we might not be able to transfer manufacturing to a third party. Even if we could transfer manufacturing to a third party, the shift would likely be expensive and time-consuming, particularly since the new facility would need to comply with the necessary regulatory requirements and we would need FDA, NMPA or and other comparable regulatory agency approval before selling any drugs manufactured at that facility. Such an event could delay our clinical trials or reduce our product sales if and when we are able to successfully commercialize one or more of our drug candidates.

Any interruption in manufacturing operations at our manufacturing facilities could result in our inability to satisfy the demands of our clinical trials or commercialization. A number of factors could cause interruptions, including:

	•	the continued suspension of our operations at the Chongqing facility or the termination of operations at the facility by the DEMC;
	•	regulatory holds on operations at the facilities or the loss of permits to operate facilities;
	•	equipment malfunctions or failures;
	•	malfunctions or compromise by third party actors of our technology systems;
	•	work stoppages;
	•	damage to or destruction of either facility due to natural disasters;
	•	regional power shortages;
	•	product tampering; or
	•	terrorist activities.

Any disruption that impedes our ability to manufacture our drug candidates in a timely manner could materially harm our business, financial condition and operating results.

Specifically, operations at our plant in Chongqing, China are currently suspended based on discussions with the DEMC and concerns raised by the DEMC related to the location of our plant. If we are unable to resume operations at that facility and if we are unable to find alternate suppliers of our product candidates, specifically tirbanibulin, oral paclitaxel and encequidar, we may have to delay our scheduled development of our product candidates. If we are unable to perform the clinical testing required to obtain regulatory approval, we will be unable to commercialize our product candidates.

Currently, we maintain insurance coverage against damage to our property and equipment. However, our insurance coverage may not reimburse us, or may not be sufficient to reimburse us, for any expenses or losses we may suffer. We may be unable to meet our requirements for our drug candidates if there were a catastrophic event or failure of our manufacturing facilities or processes.

Risks Related to Government Regulation

Recently enacted and future legislation may increase the difficulty and cost for us to obtain regulatory approval of and commercialize our drug candidates and affect the prices we may obtain.

In the U.S., China and certain other jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay regulatory approval of our drug candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any drug candidates for which we obtain regulatory approval.

In the U.S., the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, changed the way Medicare covers and pays for pharmaceutical products. The legislation expanded Medicare coverage for drug purchases by the elderly and introduced a new reimbursement methodology based on average sales prices for physician-administered drugs. In addition, this legislation provided authority for limiting the number of drugs that will be covered in any therapeutic class. Cost reduction initiatives and other provisions of this legislation could decrease the coverage and price that we receive for any approved products. While the MMA only applies to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private payors.

The Affordable Care Act, or ACA, included provisions to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms.

Among the provisions of the ACA of importance to our potential drug candidates are the following:

	•	an annual, nondeductible fee on any entity that manufactures or imports specified branded prescription drugs and biologics;
	•	an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program;
	•	expansion of healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute, new government investigative powers, and enhanced penalties for noncompliance;
	•	a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale discounts off negotiated prices;
	•	extension of manufacturers’ Medicaid rebate liability;
	•	expansion of eligibility criteria for Medicaid programs;
	•	expansion of the entities eligible for discounts under the Public Health Service Act pharmaceutical pricing program;
	•	requirements to report payments and other transfers of value made to physicians or teaching hospitals;
	•	a requirement to annually report drug samples that manufacturers and distributors provide to physicians and
	•	a Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research.

In addition, other legislative changes have been proposed and adopted in the U.S. since the ACA was enacted. These changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year, starting in 2013. In January 2013, the American Taxpayer Relief Act of 2012 was enacted, which, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding.

We expect that the ACA, as well as other healthcare reform legislative measures that have been since adopted or may be adopted in the future, may result in more rigorous coverage criteria and an additional downward pressure on the price that we receive for any approved drug. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our drugs. In particular, we expect that the current presidential administration and U.S. Congress will seek to modify, repeal, or otherwise invalidate all, or certain provisions of, the ACA. Most recently, the Tax Cuts and Jobs Act was enacted, which, among other things, removes penalties for not complying with the individual mandate to carry health insurance. There is still uncertainty with respect to the impact President Trump’s administration and the U.S. Congress may have, if any, and any changes will likely take time to unfold. Such reforms could have an adverse effect on anticipated revenues from therapeutic candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop therapeutic candidates. However, we cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us.

Other legislative and regulatory proposals have been made to expand post-approval requirements and restrict coverage and reimbursement and sales and promotional activities, for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether agencies such as the FDA or Centers for Medicare and Medicaid Services will issue new regulations, guidance or interpretations that may impact our drug candidates. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay or prevent regulatory approval, as well as subject us to more stringent product labeling and post-marketing testing and other requirements.

We are subject, directly or indirectly, to applicable U.S. federal and state anti-kickback, false claims laws, physician payment transparency laws, fraud and abuse laws or similar healthcare and privacy and security laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians and others play a primary role in the recommendation and prescription of our products and any of our product candidates for which we obtain regulatory approval. Our operations are subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act and physician payment transparency laws and regulations. These laws may impact, among other things, our proposed sales and marketing programs as well as any patient support programs we may consider offering. In addition, we may be subject to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:

	•	the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual, or the purchase, lease, order or recommendation of any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs;
	•	federal civil and criminal false claims laws and civil monetary penalty laws, such as the federal False Claims Act which imposes criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval from Medicare, Medicaid or other third-party payors that are false or fraudulent, including failure to timely return an overpayment received from the federal government or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;
	•	provisions of HIPAA, which created new federal criminal statutes referred to as the “HIPAA All-Payor Fraud Prohibition,” prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters;
	•	provisions of HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 and their respective implementing regulations, which impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses as well as their respective business associates that perform services for them that involve the use, or disclosure of, individually identifiable health information, relating to the privacy, security and transmission of individually identifiable health information without appropriate authorization;
	•	the federal transparency requirements under the ACA, including the provision commonly referred to as the Physician Payments Sunshine Act, which requires manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program to report annually to the U.S. Department of Health and Human Services information related to all payments or other transfers of value made to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members unless a specific exclusion applies; and
	•	federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers.

Additionally, we are subject to state and non-U.S. equivalents of each of the healthcare laws described above, among others, some of which may be broader in scope and may apply regardless of the payor. Many U.S. states have adopted laws similar to the Federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare services reimbursed by any source, not just governmental payors, including private insurers. In addition, some states have passed laws that require pharmaceutical companies to comply with the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers of America’s Code on Interactions with Healthcare Professionals. Several states also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the state. There are ambiguities as to what is required to comply with these state requirements and if we fail to comply with an applicable state law requirement, we could be subject to penalties.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, recent health care reform legislation has strengthened these laws. For example, the ACA, among other things, amends the intent requirement of the federal Anti-Kickback and criminal healthcare fraud statutes. As a result of such amendment, a person or entity no longer needs to have actual knowledge of these statutes or specific intent to violate them in order to have committed a violation. Moreover, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including penalties, fines and/or exclusion or suspension from federal and state healthcare programs such as Medicare and Medicaid and debarment from contracting with the U.S. government. In addition, private individuals have the ability to bring actions on behalf of the U.S. government under the Federal False Claims Act as well as under the false claims laws of several states.

Law enforcement authorities are increasingly focused on enforcing these laws, and it is possible that some of our practices may be challenged under these laws. Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, the approval and commercialization of any of our drug candidates outside the U.S. will also likely subject us to non-U.S. equivalents of the healthcare laws mentioned above, among other non-U.S. laws.

If any of the physicians or other providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

Lastly, political, economic and regulatory influences are subjecting the health care industry in the U.S. to fundamental change. Initiatives to reduce the federal budget and debt and to reform health care coverage are increasing cost-containment efforts. We anticipate that federal agencies, Congress, state legislatures, and the private sector will continue to review and assess alternative health care benefits, controls on health care spending, and other fundamental changes to the healthcare delivery system. Any proposed or actual changes could limit coverage for or the amounts that federal and state governments will pay for health care products and services, which could also result in reduced demand for our products or additional pricing pressures, and limit or eliminate our spending on development projects and affect our ultimate profitability.

Our business is subject to applicable laws and regulations relating to sanctions, anti-money laundering and anti-bribery practices, the violation of which could adversely affect our operations.

We must comply with all applicable economic sanctions, anti-money laundering and anti-bribery laws and regulations of the U.S. and other foreign jurisdictions where we operate, including China. U.S. laws and regulations applicable to us include the economic trade sanctions laws and regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control, or OFAC, as well as certain laws administered by the U.S. Department of State. Our business is also subject to anti-money laundering laws and regulations, including the Proceeds of Crime Act 2002, the Terrorism Act 2000 and the Money Laundering Regulations 2007 in the U.K., the Bank Secrecy Act of 1970, the Money Laundering Control Act of 1986 and the USA PATRIOT Act of 2001 in the U.S. and equivalent or similar legislation in the other countries where we do business. In addition, we are subject to the Foreign Corrupt Practices Act of 1977, or FCPA, and other anti-bribery laws such as the U.K. Bribery Act 2010 that generally prohibit the corrupt provision of anything of value to foreign governments and their officials and political parties for the purpose of influencing official conduct or obtaining or retaining an undue business advantage. Applicable anti-bribery laws also may prohibit commercial bribery.

We have operations, conduct clinical trials, deal with government entities, including hospitals and public health regulators, and have contracts in countries known to experience corruption and commercial bribery. Our activities in these countries, particularly China and countries in Latin America, create the risk of unauthorized payments or offers of payments by our employees, brokers or agents that could be in violation of various laws, including the FCPA, even though these parties are not always subject to our control and supervision. Corruption, extortion, bribery, pay-offs, theft and other fraudulent practices occur from time-to-time in China, where we conduct business. There is no assurance that our existing safeguards and procedures will be completely effective in ensuring compliance with such laws, and our employees, brokers or agents may engage in conduct for which we may be held responsible. Violations of the FCPA or other anti-bribery laws may result in severe criminal or civil sanctions, and we may be subject to other liabilities, which could negatively affect our reputation, business, operating results, and financial condition.

Regulations administered by OFAC govern transactions with countries and persons subject to U.S. trade sanctions. We are also subject to U.S. Government restrictions on transactions with specific entities and individuals, including, without limitation, those set forth on the Entity List, the Specially Designated Nationals List, the Denied Persons List, the Unverified List, and the U.S. State Department’s lists of debarred parties and sanctioned entities, and we may also be subject to restrictions on transactions with specific entities and individuals subject to the sanctions administered by the United Nations Security Council, the EU, Her Majesty’s Treasury, or other relevant sanctions authority. These regulations prohibit us from entering into or facilitating unlicensed transactions with, for the benefit of, or in some cases involving the property and property interests of such persons, governments, or countries designated by the relevant sanctions authority under one or more sanctions regimes. Failure to comply with these sanctions and embargoes may result in material fines, sanctions or other penalties being imposed on us or other governmental investigations. In addition, various state and municipal governments, universities and other investors maintain prohibitions or restrictions on investments in companies that do business involving sanctioned countries or entities.

International economic and trade sanctions are complex and subject to frequent change, including jurisdictional reach and the lists of countries, entities, and individuals subject to the sanctions. Current or future economic and trade sanctions regulations or developments might have a negative impact on our business or reputation, and we may incur significant costs related to current, new, or changing sanctions programs, as well as investigations, fines, fees or settlements, which may be difficult to predict. In addition, companies subject to SEC reporting obligations are required under Section 13 of the Exchange Act to disclose in their periodic reports specified dealings or transactions involving Iran or other individuals and entities targeted by certain sanctions promulgated by OFAC that the reporting company or any of its affiliates engaged in during the period covered by the relevant periodic report. In some cases, Section 13 requires companies to disclose transactions even if they are permissible under U.S. law. The SEC is required to post this notice of disclosure pursuant to Section 13 on its website and report to the President and certain congressional committees regarding such filings.

Although we have policies and controls in place that are designed to ensure compliance with these laws and regulations, it is possible that an employee or intermediary could fail to comply with applicable laws and regulations. In such event, we could be exposed to civil penalties, criminal penalties and other sanctions, including fines or other punitive actions, and the government may seek to impose modifications to business practices, including cessation of business activities in sanctioned countries, and modifications to compliance programs, which may increase compliance costs. In addition, such violations could damage our business and/or our reputation. Such criminal or civil sanctions, penalties, other sanctions, and damage to our business and/or reputation could have a material adverse effect on our financial condition and results of operations.

Any failure to comply with applicable regulations and industry standards or obtain various licenses and permits could harm our reputation and our business, results of operations and prospects.

A number of governmental agencies or industry regulatory bodies in the U.S., and in non-U.S. jurisdictions including China and countries in Latin America, impose strict rules, regulations and industry standards governing pharmaceutical and biotechnology research and development and manufacturing and marketing activities, which apply to us. Our failure to comply with such regulations could result in the termination of ongoing research or manufacturing and marketing, administrative penalties imposed by regulatory bodies or the disqualification of data for submission to regulatory authorities. This could harm our reputation, prospects for future work and operating results. For example, if we were to treat research animals inhumanely or in violation of international standards set out by the Association for Assessment and Accreditation of Laboratory Animal Care, it could revoke any such accreditation and the accuracy of our animal research data could be questioned.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

Although we maintain workers’ compensation insurance to cover us for costs and expenses, we may incur due to injuries to our employees resulting from the use of or exposure to hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage, use or disposal of biological or hazardous materials.

In addition, we may be required to incur substantial costs to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

If we face allegations of noncompliance with the law and encounter sanctions, our reputation, revenues and liquidity may suffer, and our drugs could be subject to restrictions or withdrawal from the market.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenues from our drugs. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating results will be adversely affected. Additionally, if we are unable to generate revenues from our product sales, our potential for achieving profitability will be diminished and the capital necessary to fund our operations will be increased.

Risks Related to Our Doing Business in China

The pharmaceutical industry in China is highly regulated and such regulations are subject to change which may affect approval and commercialization of our drugs.

Certain of our research operations and manufacturing facilities are in China. The pharmaceutical industry in China is subject to comprehensive government regulation and supervision, encompassing the approval, registration, manufacturing, packaging, licensing and marketing of new drugs. In recent years, the regulatory framework in China regarding the pharmaceutical industry has undergone significant changes, and we expect that it will continue to undergo significant changes. Any such changes or amendments may result in increased compliance costs on our business or cause delays in or prevent the successful development or commercialization of our drug candidates in China and reduce the current benefits we believe are available to us from developing and manufacturing drugs in China. Chinese authorities have become increasingly vigilant in enforcing laws in the pharmaceutical industry and any failure by us or our partners to maintain compliance with applicable laws and regulations or obtain and maintain required licenses and permits may result in the suspension or termination of our business activities in China. We believe our strategy and approach is aligned with the Chinese government’s policies, but we cannot ensure that our strategy and approach will continue to be aligned.

Fluctuations in exchange rates could result in foreign currency exchange losses, which may adversely affect our financial condition, results of operations and cash flows.

We incur portions of our expenses, and may in the future derive revenues, in currencies other than U.S. dollars, in particular, the RMB. As a result, we are exposed to foreign currency exchange risk as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates. For example, a portion of our clinical trial activities are conducted outside of the U.S., and associated costs may be incurred in the local currency of the country in which the trial is being conducted, which costs could be subject to fluctuations in currency exchange rates. We currently do not engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the U.S. dollar. A decline in the value of the U.S. dollar against currencies in countries in which we conduct clinical trials could have a negative impact on our research and development costs.

The value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions and the foreign exchange policy adopted by China and other non-U.S. governments. Specifically in China, on July 21, 2005, the Chinese government changed its policy of pegging the value of the RMB to the U.S. dollar. Following the removal of the U.S. dollar peg, the RMB appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RMB and the U.S. dollar remained within a narrow band. Since June 2010, the Chinese government has allowed the RMB to appreciate slowly against the U.S. dollar again, and it has appreciated more than 10% since June 2010. In April 2012, the Chinese government announced that it would allow more RMB exchange rate fluctuation and in August 2015, China’s central bank executed a 2% devaluation in the RMB. From December 31, 2016 to December 31, 2017, the RMB appreciated approximately 6.3% against the U.S. dollar. From December 31, 2017 to December 31, 2018, the RMB depreciated approximately 5.6% against the U.S. dollar. From December 31, 2018 to June 30, 2019, the RMB appreciated approximately 0.4% against the U.S. dollar. It remains unclear what further fluctuations may occur or what impact this will have on the currency and our results of operations.

It is difficult to predict how market forces or China, U.S. or other government policies may impact the exchange rate between the RMB, U.S. dollar and other currencies in the future. There remains significant international pressure on the Chinese government to adopt a more flexible currency policy, which could result in greater fluctuation of the RMB against the U.S. dollar. Substantially all of our revenues are denominated in U.S. dollars and our costs are denominated in U.S. dollars and RMB, and a large portion of our

financial assets is denominated in U.S. dollars. Generally, to the extent that we need to convert U.S. dollars into RMB for our operations, appreciation of the RMB against the U.S. dollar would have an adverse effect on the RMB amount we would receive. Conversely, if we decide to convert our RMB into U.S. dollars for other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount we would receive. We cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely affect our financial condition, results of operations and cash flows.

Changes in the political and economic policies of the Chinese government may materially and adversely affect our business, financial condition and results of operations and may result in our inability to sustain our growth and expansion strategies.

A significant portion of our operations are in China. Accordingly, our financial condition and results of operations are affected to a large extent by economic, political and legal developments in China.

The Chinese economy differs from the economies of most developed countries in many respects, including the extent of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets, and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over China’s economic growth by allocating resources, controlling payment of foreign currency-denominated obligations, setting monetary policy, regulating financial services and institutions and providing preferential treatment to particular industries or companies.

While the Chinese economy has experienced significant growth in the past three decades, growth has been uneven, both geographically and among various sectors of the economy. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures may benefit the overall Chinese economy, but may also have a negative effect on us. Our financial condition and results of operation could be materially and adversely affected by government control over capital investments or changes in tax regulations that are applicable to us and consequently have a material adverse effect on our businesses, financial condition and results of operations.

Tariffs imposed by the U.S. and those imposed in response by other countries, as well as rapidly changing trade relations, could have a material adverse effect on our business and results of operations.

Changes in U.S. and foreign governments’ trade policies have resulted in, and may continue to result in, tariffs on imports into and exports from the U.S. Throughout 2018 and 2019, the U.S. imposed tariffs on imports from several countries, including China. In response, China has proposed and implemented their own tariffs on certain products, which may impact our supply chain and our costs of doing business. If we are impacted by the changing trade relations between the U.S. and China, our business and results of operations may be negatively impacted. Continued diminished trade relations between the U.S. and other countries, including potential reductions in trade with China and others, as well as the continued escalation of tariffs, could have a material adverse effect on our financial performance and results of operations.

There are uncertainties regarding the interpretation and enforcement of laws, rules and regulations in China.

A portion of our operations are conducted in China through our Chinese subsidiaries, and are governed by Chinese laws, rules and regulations. Our Chinese subsidiaries are subject to laws, rules and regulations applicable to foreign investment in China. The Chinese legal system is a civil law system based on written statutes. Unlike the common law system, prior court decisions may be cited for reference but have limited precedential value.

In 1979, the Chinese government began to promulgate a comprehensive system of laws, rules and regulations governing economic matters in general. The overall effect of legislation over the past few decades has significantly enhanced the protections afforded to various forms of foreign investment in China. However, China has not developed a fully integrated legal system, and recently enacted laws, rules and regulations may not sufficiently cover all aspects of economic activities in China or may be subject to significant degrees of interpretation by Chinese regulatory agencies. In particular, because these laws, rules and regulations are relatively new, and because of the limited number of published decisions and the nonbinding nature of such decisions, and because the laws, rules and regulations often give the relevant regulator significant discretion in how to enforce them, the interpretation and enforcement of these laws, rules and regulations involve uncertainties and can be inconsistent and unpredictable. In addition, the Chinese legal system is based in part on government policies and internal rules, some of which are not published on a timely basis or at all, and which may have a retroactive effect. As a result, we may not be aware of our violation of these policies and rules until after the occurrence of the violation.

Any administrative and court proceedings in China may be protracted, resulting in substantial costs and diversion of resources and management attention. Since Chinese administrative and court authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to enforce the contracts we have entered into and could materially and adversely affect our business, financial condition and results of operations.

Substantial uncertainties exist with respect to the enactment, interpretation and implementation of Chinese Foreign Investment Law and Negative List and how they may impact the viability of our current corporate governance.

On March 15, 2019, the National People’s Congress of the PRC promulgated the Foreign Investment Law of the People’s Republic of China (the “FIL”) which will become effective on January 1, 2020. Simultaneously, the three foreign investment laws (i.e. the Wholly Foreign-Owned Enterprise Law, the Sino-Foreign Equity Joint Venture Enterprise Law, and the Sino-Foreign Cooperative Joint Venture Enterprise Law) will be repealed on January 1, 2020. Pursuant to the FIL, foreign investors shall not invest in any field forbidden by the negative list for access of foreign investment. For any field on the negative list, foreign investors shall conform to the investment conditions provided in the negative list. Fields not included in the negative list shall be managed under the principle that domestic investment and foreign investment shall be treated uniformly. According to the FIL, the organization form and institutional framework shall be subject to the provisions of the Company Law of the People's Republic of China, the Partnership Enterprise Law of the PRC, and other PRC laws. Foreign invested enterprises, which were established in accordance with the aforesaid three foreign investment laws may retain their original organization forms and other aspects for five years after the implementation of the FIL. Specific implementation measures shall be formulated by the State Council of the PRC.

In June 2017 the National Development and Reform Commission and the Ministry of Commerce jointly issued Catalogue of Industries for Guiding Foreign Investment (2017 Revision), which introduced Special Administrative Measures on Access of Foreign Investment (“Negative List”). Any industry not listed in the catalogue and Negative List is a permitted industry, and is generally open to foreign investment unless specifically prohibited or restricted by the Chinese laws and regulations. The Negative List is further divided into restricted foreign-invested industries and prohibited foreign-invested industries. The Negative List was further revised in 2018 and 2019. The most updated Negative List was issued on June 30, 2019 and takes effect on July 30, 2019.

The FIL and Negative List may also materially impact our corporate governance practice and increase our compliance costs. For instance, the FIL imposes stringent ad hoc and periodic information reporting requirements on foreign investors and the applicable FIEs. Aside from investment implementation report and investment amendment report that are required at each investment and alteration of investment specifics, an annual report is mandatory, and large foreign investors meeting certain criteria are required to report on a quarterly basis. Any company found to be non-compliant with these information reporting obligations may potentially be subject to fines and/or administrative or criminal liabilities, and the persons directly responsible may be subject to criminal liabilities.

Chinese regulations relating to investments in offshore companies by Chinese residents may subject our future Chinese-resident beneficial owners or our Chinese subsidiaries to liability or penalties, limit our ability to inject capital into our Chinese subsidiaries or limit our Chinese subsidiaries’ ability to increase their registered capital or distribute profits.

The SAFE promulgated the Circular on Relevant Issues Concerning Foreign Exchange Control on Domestic Residents’ Offshore Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, on July 4, 2014, which replaced the former circular, commonly known as SAFE Circular 75, promulgated by SAFE on October 21, 2005. According to Notice on Further Simplifying and Improving Policies for the Foreign Exchange Administration of Direct Investment, the “Circular 13”, which became effective on June 1, 2015, banks shall directly examine and handle foreign exchange registration under domestic direct investment and foreign exchange registration under overseas direct investment, and the SAFE and its branch offices shall indirectly regulate the foreign exchange registration of direct investment through banks. SAFE Circular 37, Circular 13 and other SAFE rules require Chinese residents to register with local branches of SAFE or delegated commercial banks in connection with their direct establishment or indirect control of an offshore entity, for the purpose of overseas investment and financing, with such Chinese residents’ legally owned assets or equity interests in domestic enterprises or offshore assets or interests, referred to in SAFE Circular 37 as a “special purpose vehicle”. SAFE Circular 37 further requires amendment to the registration in the event of any significant changes with respect to the special purpose vehicle, such as increase or decrease of capital contributed by Chinese individuals, share transfer or exchange, merger, division or other material events. In the event that a Chinese stockholder holding interests in a special purpose vehicle fails to fulfill the required registration, the Chinese subsidiaries of that special purpose vehicle may be prohibited from making profit distributions to the offshore parent and from carrying out subsequent cross-border foreign exchange activities, and the special purpose vehicle may be restricted in its ability to contribute additional capital into its Chinese subsidiary. Moreover, failure to comply with the various registration requirements described above could result in liability under Chinese law for evasion of foreign exchange controls.

We believe that certain of our stockholders are Chinese residents under SAFE Circular 37. These certain stockholders have undertaken to (i) apply to register with local SAFE branch or its delegated commercial bank as soon as possible after exercising their options and (ii) indemnify and hold harmless us and our subsidiaries against any loss suffered arising from their failure to complete the registration. We do not have control over the stockholders and our other beneficial owners and cannot assure you that all of our Chinese-resident beneficial owners have complied with, and will in the future comply with, SAFE Circular 37 and subsequent implementation rules. The failure of Chinese-resident beneficial owners to register or amend their SAFE registrations in a timely manner pursuant to SAFE Circular 37 and subsequent implementation rules, or the failure of future Chinese-resident beneficial owners of our company to comply with the registration procedures set forth in SAFE Circular 37 and subsequent implementation rules, may subject such beneficial owners or our Chinese subsidiaries to fines and legal sanctions. Furthermore, SAFE Circular 37 is unclear how this regulation, and any future regulation concerning offshore or cross-border transactions, will be interpreted, amended and implemented by the relevant Chinese government authorities, and we cannot predict how these regulations will affect our business operations or future strategy. Failure to register or comply with relevant requirements may also limit our ability to contribute additional capital to our Chinese subsidiaries and limit our Chinese subsidiaries’ ability to distribute dividends to us. These risks could in the future have a material adverse effect on our business, financial condition and results of operations.

Any failure to comply with Chinese regulations regarding the registration requirements for employee share option plans may subject the Chinese plan participants or us to fines and other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Share Incentive Plans of Overseas Publicly-Listed Companies, commonly known as SAFE Circular 7, or the Share Option Rules, replacing earlier rules promulgated in 2007. Pursuant to these rules, Chinese residents who are granted shares or share options by companies listed on overseas stock exchanges under share incentive plans are required to (1) register with the SAFE or its local branches; (2) retain a qualified Chinese agent, which may be a Chinese subsidiary of the overseas listed company or another qualified institution selected by the Chinese subsidiary, to conduct the SAFE registration and other procedures with respect to the share incentive plans on behalf of the participants and (3) retain an overseas institution to handle matters in connection with their exercise of share options, purchase and sale of shares or interests and funds transfers. We and our executive officers and other employees who are Chinese residents and who have been granted options will be subject to these regulations. Failure to complete the SAFE registrations may subject them to fines, and legal sanctions, and may also limit our ability to contribute additional capital into our Chinese subsidiary and limit our Chinese subsidiary’s ability to distribute dividends to us. We also face regulatory uncertainties that could restrict our ability to adopt additional incentive plans for our directors, executive officers and employees under Chinese law.

We may be treated as a resident enterprise for Chinese tax purposes under the Chinese Enterprise Income Tax Law, and we may therefore be subject to Chinese income tax on our global income.

Under the Chinese Enterprise Income Tax Law and its implementing rules, both of which came into effect on January 1, 2008, as amended on February 24, 2017 and December 29, 2018, enterprises established under the laws of jurisdictions outside of China with “de facto management bodies” located in China may be considered Chinese tax resident enterprises for tax purposes and may be subject to the Chinese enterprise income tax at the rate of 25% on their global income. “De facto management body” refers to a managing body that exercises substantive and overall management and control over the production and business, personnel, accounting books and assets of an enterprise. The State Administration of Taxation has issued guidance, known as Circular 82 that provides certain specific criteria for determining whether the “de facto management body” of a Chinese-controlled offshore-incorporated enterprise is located in China. Although Circular 82 only applies to offshore enterprises controlled by Chinese enterprises, not those, such as us, controlled by foreign enterprises or individuals, the determining criteria set forth in Circular 82 may reflect the State Administration of Taxation’s general position on how the “de facto management body” test should be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by Chinese enterprises. Although the reviewing procedure in Circular 82 was simplified on December 29, 2017, pursuant to Decision of the SAT on Issuing the Catalogues of Tax Departmental Rules and Tax Regulatory Documents Which Are Invalidated, the “de facto management body” test is still valid. Currently, our management is located in the U.S., and we generate a portion of our revenues within China and a portion outside China. We believe that neither we nor any of our subsidiaries outside of China is a Chinese resident enterprise for Chinese tax purposes. However, the tax resident status of an enterprise is subject to determination by the Chinese tax authorities and uncertainties remain with respect to the interpretation of the term “de facto management body”. If we were to be considered a Chinese resident enterprise, we would be subject to Chinese enterprise income tax at the rate of 25% on our global income. In such case, our profitability and cash flow may be materially reduced as a result of our global income being taxed under the Chinese Enterprise Income Tax Law.

Dividends payable to our foreign investors and gains on the sale of our common stock by our foreign investors may become subject to Chinese tax law.

Under the Chinese Enterprise Income Tax Law and its implementing rules issued by the State Council, in general, a 10% Chinese withholding tax is applicable to dividends payable to investors that are non-resident enterprises that do not have an establishment or place of business in China or which have such establishment or place of business but the dividends are not effectively connected with such establishment or place of business, to the extent such dividends are derived from sources within China. Similarly, any gain realized on the transfer of shares of our common stock by such investors is also subject to Chinese tax at a current rate of 10%, subject to any reduction or exemption set forth in relevant tax treaties, if such gain is regarded as income derived from sources within China. If we are deemed a Chinese resident enterprise, dividends paid on our common stock, and any gain realized from the transfer of our common stock, would be treated as income derived from sources within China and would as a result be subject to Chinese taxation. Furthermore, if we are deemed a Chinese resident enterprise, dividends payable to individual investors who are non-Chinese residents and any gain realized on the transfer of common stock by such investors may be subject to Chinese tax at a current rate of 20%, subject to any reduction or exemption set forth in applicable tax treaties. It is unclear whether we or any of our subsidiaries established outside China are considered a Chinese resident enterprise, holders of our common stock would be able to claim the benefit of income tax treaties or agreements entered into between China and other countries or areas. If dividends payable to our non-Chinese investors or gains from the transfer of our common stock by such investors are subject to Chinese tax, the value of your investment in our common stock may decline significantly.

We and our stockholders face uncertainties with respect to indirect transfers of equity interests in Chinese resident enterprises by their non-Chinese holding companies.

Pursuant to a notice, or Circular 698, issued by the State Administration of Taxation, where a non-resident enterprise conducts an “indirect transfer” by transferring the equity interests of a Chinese resident enterprise indirectly via disposing of the equity interests of an overseas holding company, and such overseas holding company is located in a tax jurisdiction that: (1) has an effective tax rate less than 12.5% or (2) does not tax foreign income of its residents, the non-resident enterprise, being the transferor, shall report to the relevant tax authority of the Chinese resident enterprise such indirect transfer. Using a “substance over form” principle, the Chinese tax authority may disregard the existence of the overseas holding company if it lacks a reasonable commercial purpose and was established for the purpose of reducing, avoiding or deferring Chinese tax. As a result, gains derived from such indirect transfer may be subject to Chinese enterprise income tax, currently at a rate of 10%. In 2015, the State Administration of Taxation issued a circular, known as Circular 7, which replaced or supplemented certain previous rules under Circular 698. Circular 7 sets out a wider scope of indirect transfer of Chinese assets that might be subject to Chinese enterprise income tax, and more detailed guidelines on the circumstances when such indirect transfer is considered to lack a bona fide commercial purpose and thus regarded as avoiding Chinese tax. The conditional reporting obligation of the non-Chinese investor under Circular 698 is replaced by a voluntary reporting by the transferor, the transferee or the underlying Chinese resident enterprise being transferred. Furthermore, if the indirect transfer is subject to Chinese enterprise income tax, the transferee has an obligation to withhold tax from the sale proceeds, unless the transferor reports the transaction to the Chinese tax authority under Circular 7. Late payment of applicable tax will subject the transferor to default interest. Gains derived from the sale of shares by investors through a public stock exchange are not subject to the Chinese enterprise income tax pursuant to Circular 7 where such shares were acquired in a transaction through a public stock exchange. Circular 698 was abolished by an announcement promulgated by the State Administration of Taxation in October 2017 and effective from December 1, 2017, or SAT Circular 37, which, among other things, provides specific provisions on matters concerning withholding of income tax of non-resident enterprises at the source.

As newly implemented, there is uncertainty as to the application of Circular 7 and SAT Circular 37, both of which may be determined by the tax authorities to be applicable to our offshore restructuring transactions or sale of the shares of our offshore subsidiaries where non-resident enterprises, being the transferors, were involved. The Chinese tax authorities may pursue such non-resident enterprises with respect to a filing regarding the transactions and request our Chinese subsidiaries to assist in the filing. As a result, we and our non-resident enterprises in such transactions may become at risk of being subject to filing obligations or being taxed under Circular 7, and may be required to expend valuable resources to comply with Circular 7 or to establish that we and our non-resident enterprises should not be taxed under Circular 7, for our previous and future restructuring or disposal of shares of our offshore subsidiaries, which may have a material adverse effect on our financial condition and results of operations.

Restrictions on currency exchange may limit our ability to utilize our revenue effectively.

The Chinese government imposes controls on the convertibility of RMB into foreign currencies and, in certain cases, the remittance of currency out of China. A portion of our revenue may in the future be denominated in RMB. Shortages in availability of foreign currency may then restrict the ability of our Chinese subsidiaries to remit sufficient foreign currency to our offshore entities for our offshore entities to pay dividends or make other payments or otherwise to satisfy our foreign currency denominated obligations. The RMB is currently convertible under the “current account,” which includes dividends, trade and service-related foreign

exchange transactions, but not under the “capital account”, which includes foreign direct investment and loans, including loans we may secure from our onshore subsidiaries. Currently, our Chinese subsidiaries, which are wholly-foreign owned enterprises, may purchase foreign currency for settlement of “current account transactions,” including payment of dividends to us, without the approval of SAFE by complying with certain procedural requirements. However, the relevant Chinese governmental authorities may limit or eliminate our ability to purchase foreign currencies in the future for current account transactions. Since a portion of our future revenue may be denominated in RMB, any existing and future restrictions on currency exchange may limit our ability to utilize revenue generated in RMB to fund our business activities outside of China or pay dividends in foreign currencies to our stockholders, including holders of our common stock. Foreign exchange transactions under the capital account remain subject to limitations and require approvals from, or registration with, SAFE and other relevant Chinese governmental authorities. This could affect our ability to obtain foreign currency through debt or equity financing for our subsidiaries.

Recent litigation and negative publicity surrounding China-based companies listed in the U.S. may result in increased regulatory scrutiny of us and negatively impact the trading price of our common stock and could have a material adverse effect upon our business, including our results of operations, financial condition, cash flows and prospects.

We believe that litigation and negative publicity surrounding companies with operations in China, including concerning the directors and officers of such companies, that are listed in the U.S. have negatively impacted stock prices for such companies. Various equity-based research organizations have published reports on China-based companies after examining, among other things, their corporate governance practices, related party transactions, sales practices and financial statements that have led to special investigations and stock suspensions on national exchanges, including as a result of purported whistle-blowing or leaking by employees or former employees. Any similar scrutiny of us, regardless of its lack of merit, could result in a diversion of management resources and energy, potential costs to defend ourselves against rumors, decreases and volatility in the trading price of our common stock, and increased directors and officers insurance premiums and could have a material adverse effect upon our business, including our results of operations, financial condition, cash flows and prospects.

Risks Related to Our Common Stock

The trading price of our common stock has been and is likely to continue to be volatile, which could result in substantial losses to you.

The trading price of our common stock has been and is likely to continue to be volatile and could fluctuate widely in response to a variety of factors, many of which are beyond our control. In addition, the performance and fluctuation of the market prices of other companies with a portion of their business operations located in China that have listed their securities in the U.S. may affect the volatility in the price of and trading volumes for our common stock. Some of these companies have experienced significant volatility, including significant price declines after their initial public offerings. The trading performances of these companies’ securities at the time of or after their offerings may affect the overall investor sentiment towards other companies with significant China operations listed in the U.S. and consequently may impact the trading performance of our common stock.

In addition to market and industry factors, the price and trading volume for our common stock may be highly volatile for specific business reasons, including:

	•	announcements of regulatory approval or a complete response letter, or specific label indications or patient populations for its use, or changes or delays in the regulatory review process;
	•	announcements of therapeutic innovations or new products by us or our competitors;
	•	adverse actions taken by regulatory agencies with respect to our clinical trials, manufacturing supply chain or sales and marketing activities;
	•	any adverse changes to our relationship with manufacturers or suppliers;
	•	the results of our testing and clinical trials;
	•	the results of our efforts to acquire or license additional drug candidates;
	•	variations in the level of expenses related to our existing drug candidates or preclinical and clinical development programs;
	•	any intellectual property infringement actions in which we may become involved;
	•	announcements concerning our competitors or the pharmaceutical industry in general;
	•	achievement of expected product sales and profitability;

	•	manufacture, supply or distribution shortages;
	•	variations in our results of operations;
	•	announcements about our earnings that are not in line with analyst expectations, the risk of which is enhanced because it is our policy not to give guidance on earnings;
	•	publication of operating or industry metrics by third parties, including government statistical agencies, that differ from expectations of industry or financial analysts;
	•	changes in financial estimates by securities research analysts;
	•	announcements made by us or our competitors of new product and service offerings, acquisitions, strategic relationships, joint ventures or capital commitments;
	•	press reports or other negative publicity, whether or not true, about our business;
	•	additions to or departures of our management;
	•	fluctuations of exchange rates between the RMB and the U.S. dollar;
	•	release or expiry of lock-up or other transfer restrictions on our outstanding common stock;
	•	sales or perceived potential sales of additional common stock;
	•	sales of our common stock by us, our executive officers and directors or our stockholders in the future;
	•	general economic and market conditions and overall fluctuations in the U.S. equity markets;
	•	changes in accounting principles and
	•	changes or developments in China or global regulatory environment.

Any of these factors may result in large and sudden changes in the volume and trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, stockholders have often instituted securities class action litigation against that company. If we were involved in a class action suit, it could divert the attention of management, and, if adversely determined, have a material adverse effect on our financial condition and results of operations.

In addition, the stock market, in general, and small pharmaceutical and biotechnology companies have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance. Further, the current decline in the financial markets and related factors beyond our control may cause our common stock price to decline rapidly and unexpectedly.

We may be subject to securities litigation, which could result in significant legal expenses and settlement or damage awards and could divert management attention.

The price of our common stock may be volatile, and in the past companies that have experienced volatility in the market price of their common stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. We generally, to the extent permitted by law, indemnify our executive officers. Regardless, securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could harm our business.

We are currently an “emerging growth company.” As a result of the reduced disclosure requirements applicable to emerging growth companies, our common stock may be less attractive to investors.

We are currently an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012. For so long as we remain an emerging growth company, we are permitted and intend to rely on some of the exemptions from certain reporting requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include but are not limited to not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

We cannot predict whether investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and the price of our common stock may be more volatile.

Because we do not expect to pay dividends in the foreseeable future, you must rely on price appreciation of our common stock for return on your investment, if any.

We intend to retain most, if not all, of our available funds and earnings to fund the development and growth of our business. In addition, our senior secured loan agreement with Perceptive restricts our and our restricted subsidiaries’ ability to pay dividends. As a result, we do not expect to pay any cash dividends in the foreseeable future. Therefore, you should not rely on an investment in our common stock as a source for any future dividend income.

Our board of directors has significant discretion as to whether to distribute dividends. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on an investment in our common stock will likely depend entirely upon any future price appreciation of our common stock. There is no guarantee that our common stock will appreciate in value or even maintain its current market price. You may not realize a return on your investment in our common stock and you may even lose your entire investment in our common stock.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the market price for our common stock and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If research analysts do not establish and maintain adequate research coverage or if one or more of the analysts who covers us downgrades our common stock or publishes inaccurate or unfavorable research about our business, the market price for our common stock would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for our common stock to decline significantly.

There are limitations on the liability of our directors, and we may have to indemnify our officers and directors in certain instances.

Our certificate of incorporation limits, to the maximum extent permitted under Delaware law, the personal liability of our directors for monetary damages for breach of their fiduciary duties as directors. The indemnification provisions may require us, among other things, to indemnify such officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers (other than liabilities arising from willful misconduct of a culpable nature), to advance their expenses incurred as a result of certain proceedings against them as to which they could be indemnified. Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify a director, officer, employee or agent made or threatened to be made a party to an action by reason of the fact that he or she was a director, officer, employee or agent of the corporation or was serving at the request of the corporation, against expenses actually and reasonably incurred in connection with such action if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Delaware law does not permit a corporation to eliminate a director’s duty of care and the provisions of our certificate of incorporation have no effect on the availability of equitable remedies, such as injunction or rescission, for a director’s breach of the duty of care.

We believe that our limitation of officer and director liability assists us to attract and retain qualified employees and directors. However, in the event an officer, a director or the board of directors commits an act that may legally be indemnified under Delaware law, we will be responsible to pay for such officer(s) or director(s) legal defense and potentially any damages resulting there from. Furthermore, the limitation on director liability may reduce the likelihood of derivative litigation against directors and may discourage or deter stockholders from instituting litigation against directors for breach of their fiduciary duties, even though such an action, if successful, might benefit our stockholders and us. Limitations of director liability may be viewed as limiting the rights of stockholders, and the broad scope of the indemnification provisions contained in our certificate of incorporation could result in increased expenses.

Our directors, executive officers and principal stockholders have substantial control over us, which could limit your ability to influence the outcome of key transactions, including a change of control.

Our directors, officers and stockholders who own greater than 5% of our outstanding common stock, together with their affiliates, beneficially owned, in the aggregate, approximately 41% of our outstanding common stock based on the number shares outstanding as of June 30, 2019. As a result, these stockholders, if acting together, will be able to influence or control matters requiring approval by our stockholders, including the election of directors and the approval of mergers, acquisitions or other extraordinary transactions. In addition, these stockholders, acting together, would have the ability to control the management and affairs of our company. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This concentration of ownership may have the effect of delaying, preventing or deterring a change of control of our company, could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company and might ultimately affect the market price of our common stock.

In addition, our directors and officers as a group, beneficially own in the aggregate approximately 9% of our outstanding common stock based on the number shares outstanding as of June 30, 2019. As such, our directors and executive officers could have considerable influence over matters such as approving a potential acquisition of us. Our directors and executive officers’ investment in and position in our company could also discourage others from pursuing any potential acquisition of us, which could have the effect of depriving the holders of our common stock of the opportunity to sell their shares at a premium over the prevailing market price.

Anti-takeover provisions in our charter documents may discourage our acquisition by a third party, which could limit our stockholders’ opportunity to sell their shares at a premium.

Our amended and restated certificate of incorporation and bylaws include provisions that could limit the ability of others to acquire control of our company, modify our structure or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our stockholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control in a tender offer or similar transaction.

We will continue to incur increased costs as a result of operating as a public company, and our management are required to devote substantial time to compliance initiatives and corporate governance practices.

As a public company, we will continue to incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the Nasdaq Global Select Market and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices including our board and committee practices. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased our legal and financial compliance costs and have made some activities more time-consuming and costly.

We will continue to evaluate these rules and regulations on an ongoing basis. These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we are required to furnish a report by our management on our internal control over financial reporting. However, we are not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm until we issue financial statements for the year ending December 31, 2019 because we are an emerging growth company. To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. We have limited experience complying with Section 404, and such compliance may require that we incur substantial accounting expenses and expend significant management efforts. Our testing may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. In the event we identify significant deficiencies or material weaknesses in our internal controls that we cannot remediate in a timely manner, the market price of our shares could decline if investors and others lose confidence in the reliability of our financial statements, we could be subject to investigation by the SEC or other applicable regulatory authorities and our business could be harmed.
