1. Business

Odonate Therapeutics, Inc. (“Odonate” or the “Company”) is a pharmaceutical company dedicated to the development of best-in-class therapeutics that improve and extend the lives of patients with cancer. The Company’s initial focus is on the development of tesetaxel, an investigational, orally administered chemotherapy agent that belongs to a class of drugs known as taxanes, which are widely used in the treatment of cancer. Tesetaxel has several pharmacologic properties that make it unique among taxanes, including: oral administration with a low pill burden; a long (~8-day) terminal plasma half-life in humans, enabling the maintenance of adequate drug levels with relatively infrequent dosing; no history of hypersensitivity (allergic) reactions; and significant activity against chemotherapy-resistant tumors. In patients with metastatic breast cancer (“MBC”), tesetaxel was shown to have significant, single-agent antitumor activity in two multicenter, Phase 2 studies. The Company is currently conducting three studies in breast cancer. In August 2020, the Company announced positive top-line results from a multinational, multicenter, randomized, Phase 3 study of tesetaxel in MBC, known as CONTESSA. The Company’s goal for tesetaxel is to develop an effective chemotherapy choice for patients that provides quality-of-life advantages over current alternatives.

On September 1, 2020, the Company closed an underwritten public offering of 5,614,036 shares of common stock at a public offering price of $14.25 per share (collectively with the underwriters’ option, the “September 2020 Offering”). The underwriters exercised in full their option to purchase 842,105 additional shares of common stock. The aggregate gross proceeds from the September 2020 Offering were $92.0 million, and the net proceeds were $87.4 million after deducting underwriting discounts and commissions and offering costs.

As of September 30, 2020, the Company had $188.3 million in cash. The Company has incurred operating losses and negative cash flows from operations since inception. Management believes that the Company’s existing cash will be sufficient to meet the Company’s anticipated cash requirements through at least one year from the date this Quarterly Report on Form 10-Q is filed with the U.S. Securities and Exchange Commission (the “SEC”).

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The Company’s condensed financial statements contained in this Quarterly Report on Form 10-Q have been prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of SEC Regulation S-X. Accordingly, certain information and disclosures required by GAAP for annual financial statements have been omitted. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Interim financial results are not necessarily indicative of results anticipated for the full year. These condensed financial statements should be read in conjunction with the Company’s audited financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

The preparation of the Company’s condensed financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in the Company’s condensed financial statements and accompanying notes. The most significant estimates and assumptions in the Company’s condensed financial statements relate to accrued expenses and equity-based compensation expense. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these

8

estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Summary of Significant Accounting Policies

During the nine months ended September 30, 2020, there were no changes to the Company’s significant accounting policies as described in Note 2 to the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Recent Accounting Pronouncements

The Company has considered all recently issued accounting pronouncements and has concluded that there are no recently issued accounting pronouncements that may have a material impact on its results of operations, financial condition or cash flows based on current information.

3. Net Loss per Share

Basic net loss per share is calculated by dividing net loss by the weighted-average common shares outstanding during the period, without consideration of common stock equivalents. The basic net loss per share calculation excludes 1,245,685 and 1,550,643 outstanding shares of common stock held by Odonate Holdings, LLC (“Odonate Holdings”) as of September 30, 2020 and 2019, respectively, to be used to settle incentive units previously issued under the Odonate Management Holdings Equity Incentive Plan (the “Management Plan”). These shares of common stock are subject to transfer to the Company and cancellation until such incentive units are vested and exercised and, as such, are considered common stock equivalents. Therefore, the shares of common stock held by Odonate Holdings are excluded from the basic net loss per share calculation until the incentive units are exercised.

Diluted net loss per share is calculated by adjusting the weighted-average common shares outstanding for the dilutive effect of common stock equivalents outstanding for the period. Common stock equivalents, which consist of shares of common stock underlying incentive units and vested stock options, were excluded from the calculation of diluted net loss per share because they were anti-dilutive.

4. Balance Sheet Details

Property and equipment consisted of the following (in thousands):

Depreciation expense was $0.1 million and $0.3 million for the three and nine months ended September 30, 2020, respectively, and for the same periods in 2019.

Accrued expenses consisted of the following (in thousands):

5. Commitments and Contingencies

Lease Commitments

In March 2018, the Company entered into an agreement to lease office space in San Diego, California (the “San Diego Lease”) with aggregate payments of approximately $0.8 million over the term of the lease. The San Diego Lease originally provided for expiration on December 31, 2019. In August 2019, the Company entered into a First Amendment to the San Diego Lease to extend the term of the lease through the commencement of the New San Diego Lease (defined below). The San Diego Lease is classified as an operating lease.

In October 2019, the Company entered into an agreement to lease office space in San Diego, California (the “New San Diego Lease”) with aggregate payments of approximately $4.1 million over the 7.5-year term of the lease. The New San Diego Lease commenced in July 2020. The Company has an option to extend the New San Diego Lease for an additional 5 years at the end of the initial term. Further, the Company provided a standby letter of credit of $0.5 million as a security deposit during the term of the lease, subject to certain reductions beginning 4 years after the lease commencement. As of September 30, 2020, $0.5 million was pledged as collateral for the letter of credit and recorded as restricted cash. The New San Diego Lease is classified as an operating lease.

In February 2018, the Company entered into an agreement to lease office space in New York, New York (the “New York Lease”) with aggregate payments of approximately $2.8 million over the 7-year term of the lease. The Company has an option to extend the New York Lease for an additional three years at the end of the initial term. Further, the Company provided a standby letter of credit of $0.3 million in lieu of a security deposit during the term of the lease, subject to a reduction 3.5 years after the lease commencement. As of September 30, 2020, $0.3 million was pledged as collateral for the letter of credit and recorded as restricted cash. The New York lease is classified as an operating lease.

The Company recorded lease liabilities and right-of-use lease assets for the operating leases based on the present value of lease payments over the expected lease term, discounted using the Company’s incremental borrowing rate. The options to extend the operating leases were not recognized as part of the Company’s lease liabilities and right-of-use lease assets. As of September 30, 2020, the weighted-average remaining lease term and the weighted-average discount rate for the operating leases was 6.6 years and 4.0%, respectively. Rent expense under leases was $0.2 million and $0.6 million for the three and nine months ended September 30, 2020, respectively, and for the same periods in 2019. Cash paid for amounts included in the measurement of lease liabilities was $0.1 million and $0.3 million for the three and nine months ended September 30, 2020, respectively, and for the same periods in 2019.

10

Future minimum lease payments under operating leases as of September 30, 2020 are as follows (in thousands):

Other Commitments

The Company enters into contracts in the normal course of business with third-party contract research organizations, contract development and manufacturing organizations and other service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments.

Contingencies

From time to time, the Company may become subject to claims and litigation arising in the ordinary course of business. Other than as described below, the Company is not a party to any material legal proceedings, nor is it aware of any material pending or threatened litigation.

On September 16, 2020, a putative class action lawsuit was filed against the Company and the Company’s Chief Executive Officer, as well as the current and former Chief Financial Officers. The complaint was filed in the United States District Court for the Southern District of California and alleges that the Company made material misrepresentations and omissions regarding the safety and tolerability of tesetaxel in the Company’s public statements in violation of federal securities laws. The lawsuit seeks damages allegedly sustained by the class and an award of plaintiffs’ costs and attorney fees. The Company believes the complaint is without merit, and it has substantive defenses to the claims of liability and damages. The Company plans to respond accordingly. Due to the early stage of this matter, the Company is unable to estimate the possible loss or range of loss, if any, that may result from this matter.

6. Stockholders’ Equity

On September 1, 2020, the Company closed an underwritten public offering of 5,614,036 shares of common stock at a public offering price of $14.25 per share (collectively with the underwriters’ option, the “September 2020 Offering”). The underwriters exercised in full their option to purchase 842,105 additional shares of common stock. The aggregate gross proceeds from the September 2020 Offering were $92.0 million, and the net proceeds were $87.4 million after deducting underwriting discounts and commissions and offering costs.

On June 28, 2019, the Company closed an underwritten public offering of 4,750,000 shares of common stock at a public offering price of $26.00 per share (collectively with the underwriters’ option, the “June 2019 Offering”). On July 2, 2019, the underwriters exercised in full their option to purchase 712,500 additional shares of common stock. The aggregate gross proceeds from the June 2019 Offering were $142.0 million, and the net proceeds were $135.1 million after deducting underwriting discounts and commissions and offering costs.

7. Equity Incentive Plans

2017 Stock Option Plan

A total of 6,300,000 shares of common stock have been reserved for issuance under the Odonate Therapeutics, Inc. 2017 Stock Option Plan (the “2017 Plan”). As of September 30, 2020, 1,763,645 shares of common stock remained available for future grants under the 2017 Plan.

2017 Employee Stock Purchase Plan

A total of 500,000 shares of common stock have been reserved for issuance under the Odonate Therapeutics, Inc. 2017 Employee Stock Purchase Plan (the “ESPP”). As of September 30, 2020, 430,650 shares of common stock remained available for future grants under the ESPP.

Management Plan

The Company issued an aggregate of 2,931,402 incentive units under the Management Plan. Following the Company’s initial public offering in December 2017, the Company has not granted, and will no longer grant, any incentive units. As of September 30, 2020, 1,245,685 outstanding shares of common stock were held by Odonate Holdings to be used to settle incentive units previously issued under the Management Plan.

Equity Awards

The activity related to equity awards, which are comprised of stock options and incentive units, during the nine months ended September 30, 2020 is summarized as follows:

⁽¹⁾     Represents the weighted-average remaining contractual term of stock options. The incentive units have no expiration.

⁽²⁾     Aggregate intrinsic value represents the product of the number of equity awards outstanding or equity awards exercisable multiplied by the difference between the Company’s closing stock price per share on the last trading day of the period, which was $13.43 as of September 30, 2020, and the exercise price.

The total intrinsic value of equity awards exercised during the nine months ended September 30, 2020 and 2019 was $4.6 million and $7.9 million, respectively. The total fair value of equity awards vested during the nine months ended September 30, 2020 and 2019 was $9.5 million and $9.1 million, respectively.

12

Equity-based Compensation Expense

For the nine months ended September 30, 2020 and 2019, the weighted-average grant-date fair value per share was $24.02 and $17.67, respectively. The Company estimated the fair value of each stock option on the grant date using the Black-Scholes option-pricing model with the following assumptions:

Under the ESPP, eligible employees may purchase shares of the Company’s common stock twice per month at a price equal to 85% of the closing price of shares of the Company’s common stock on the date of each purchase. The benefit received by the employees, which is equal to a 15% discount on the shares of the Company’s common stock purchased, is recognized as equity-based compensation expense on the date of each purchase.

The classification of equity-based compensation expense is summarized as follows (in thousands):

As of September 30, 2020, total unrecognized compensation cost related to unvested equity awards was $54.9 million, which is estimated to be recognized over a weighted-average period of 2.7 years. As of September 30, 2020, there was no unrecognized compensation cost related to shares of common stock issued under the ESPP.

8. Income Taxes

For the three and nine months ended September 30, 2020 and 2019, the Company did not recognize a provision for income taxes due to having recorded a full valuation allowance against its deferred tax assets. As of September 30, 2020 and December 31, 2019, the Company established a full valuation allowance against its deferred tax assets due to the uncertainty surrounding the realization of such assets. As of September 30, 2020 and December 31, 2019, the Company had no unrecognized tax benefits. The Company does not anticipate there will be a significant change in unrecognized tax benefits within the next 12 months.

9. License Agreement

In 2013, the Company licensed rights to tesetaxel in all major markets from Daiichi Sankyo Company, Limited (“Daiichi Sankyo”), the original inventor of the product. Under the Daiichi Sankyo license agreement, the Company is obligated to use commercially reasonable efforts to develop and commercialize tesetaxel in the following countries: France, Germany, Italy, Spain, the United Kingdom and the U.S. The Company is required to make aggregate future milestone payments of up to $31.0 million, contingent on attainment of certain regulatory milestones. Additionally, the Company is obligated to pay Daiichi Sankyo a tiered royalty that ranges from the low- to high-single digits, depending on annual net sales of tesetaxel.

Company Overview

We are a pharmaceutical company dedicated to the development of best-in-class therapeutics that improve and extend the lives of patients with cancer. Our initial focus is on the development of tesetaxel, an investigational, orally administered chemotherapy agent that belongs to a class of drugs known as taxanes, which are widely used in the treatment of cancer. Tesetaxel has several pharmacologic properties that make it unique among taxanes, including: oral administration with a low pill burden; a long (~8-day) terminal plasma half-life in humans, enabling the maintenance of adequate drug levels with relatively infrequent dosing; no history of hypersensitivity (allergic) reactions; and significant activity against chemotherapy-resistant tumors. In patients with metastatic breast cancer (“MBC”), tesetaxel was shown to have significant, single-agent antitumor activity in two multicenter, Phase 2 studies. We are currently conducting three studies in breast cancer, as shown in the following table. In August 2020, we announced positive top-line results from a multinational, multicenter, randomized, Phase 3 study of

14

tesetaxel in MBC, known as CONTESSA. We plan to submit a New Drug Application (“NDA”) for tesetaxel to the U.S. Food and Drug Administration (“FDA”) in mid-2021. Our goal for tesetaxel is to develop an effective chemotherapy choice for patients that provides quality-of-life advantages over current alternatives.

Ongoing Tesetaxel Clinical Studies

CONTESSA

CONTESSA is a multinational, multicenter, randomized, Phase 3 study of tesetaxel, an investigational, orally administered taxane, in patients with MBC. CONTESSA is comparing tesetaxel dosed orally at 27 mg/m² on the first day of each 21 day cycle plus a reduced dose of capecitabine (1,650 mg/m²/day dosed orally for 14 days of each 21 day cycle) to the approved dose of capecitabine alone (2,500 mg/m²/day dosed orally for 14 days of each 21-day cycle) in 685 patients randomized 1:1 with human epidermal growth factor receptor 2 (“HER2”) negative, hormone receptor (“HR”) positive MBC previously treated with a taxane in the neoadjuvant or adjuvant setting. Capecitabine is an oral chemotherapy agent that is considered a standard of care treatment in MBC. Where indicated, patients must have received endocrine therapy with or without a cyclin dependent kinase (“CDK”) 4/6 inhibitor. The primary endpoint is progression-free survival (“PFS”) as assessed by an Independent Radiologic Review Committee (“IRC”). The secondary efficacy endpoints are overall survival (“OS”), objective response rate (“ORR”) as assessed by the IRC, and disease control rate (“DCR”) as assessed by the IRC.

In August 2020, we announced positive top-line results from CONTESSA. CONTESSA met the primary endpoint of improved PFS as assessed by the IRC. Median PFS was 9.8 months for tesetaxel plus a reduced dose of capecitabine versus 6.9 months for the approved dose of capecitabine alone, an improvement of 2.9 months. The risk of disease progression or death was reduced by 28.4% [hazard ratio=0.716 (95% confidence interval: 0.573-0.895); p=0.003] for patients who received tesetaxel plus a reduced dose of capecitabine versus patients who received the approved dose of capecitabine alone.

Tesetaxel plus capecitabine was associated with what we believe are manageable side effects consistent with findings from previous clinical studies. Grade ≥3 treatment-emergent adverse events (“TEAEs”) that occurred in ≥5% of patients were: neutropenia (71.2% for tesetaxel plus capecitabine vs. 8.3% for capecitabine alone); diarrhea (13.4% for tesetaxel plus capecitabine vs. 8.9% for capecitabine alone); hand foot syndrome (6.8% for tesetaxel plus capecitabine vs. 12.2% for capecitabine alone);

15

febrile neutropenia (12.8% for tesetaxel plus capecitabine vs. 1.2% for capecitabine alone); fatigue (8.6% for tesetaxel plus capecitabine vs. 4.5% for capecitabine alone); hypokalemia (8.6% for tesetaxel plus capecitabine vs. 2.7% for capecitabine alone); leukopenia (10.1% for tesetaxel plus capecitabine vs. 0.9% for capecitabine alone); and anemia (8.0% for tesetaxel plus capecitabine vs. 2.1% for capecitabine alone).

Adverse events resulting in treatment discontinuation in ≥1% of patients were: neutropenia or febrile neutropenia (4.2% for tesetaxel plus capecitabine vs. 1.5% for capecitabine alone); neuropathy (3.6% for tesetaxel plus capecitabine vs. 0.3% for capecitabine alone); diarrhea (0.9% for tesetaxel plus capecitabine vs. 1.5% for capecitabine alone); and hand-foot syndrome (0.6% for tesetaxel plus capecitabine vs. 2.1% for capecitabine alone). Treatment discontinuation due to any adverse event occurred in 23.1% of patients treated with tesetaxel plus capecitabine versus 11.9% of patients treated with capecitabine alone.

Grade 2 alopecia (hair loss) occurred in 8.0% of patients treated with tesetaxel plus capecitabine versus 0.3% of patients treated with capecitabine alone. Grade ≥3 neuropathy occurred in 5.9% of patients treated with tesetaxel plus capecitabine versus 0.9% of patients treated with capecitabine alone.

While OS data are immature, a recent interim analysis indicated the absence of an adverse effect on OS for tesetaxel plus a reduced dose of capecitabine. A protocol-specified final analysis of OS is expected to occur in 2022.

The results of CONTESSA have been selected for an oral presentation at the 2020 San Antonio Breast Cancer Symposium, to be held virtually December 8-11, 2020.

CONTESSA 2

CONTESSA 2 is a multinational, multicenter, Phase 2 study of tesetaxel, an investigational, orally administered taxane, in patients with MBC. CONTESSA 2 is investigating tesetaxel dosed orally at 27 mg/m² on the first day of each 21-day cycle plus a reduced dose of capecitabine (1,650 mg/m²/day dosed orally for 14 days of each 21-day cycle) in approximately 125 patients with HER2 negative, HR positive MBC not previously treated with a taxane. Capecitabine is an oral chemotherapy agent that is considered a standard-of-care treatment in MBC. Where indicated, patients must have received endocrine therapy with or without a CDK 4/6 inhibitor. The primary endpoint is ORR as assessed by an IRC. The secondary efficacy endpoints are duration of response (“DoR”) as assessed by the IRC, PFS as assessed by the IRC, DCR as assessed by the IRC and OS.

CONTESSA TRIO

CONTESSA TRIO is a multi-cohort, multicenter, Phase 2 study of tesetaxel, an investigational, orally administered taxane, in patients with MBC.

Components of Our Results of Operations

Research and Development Expense

Research and development expense consists primarily of expense associated with the development of tesetaxel and includes non-personnel-related and personnel-related expense. Non-personnel-related expense includes expense related to: (i) clinical study site payments; (ii) acquiring clinical study materials and the clinical study supply chain; (iii) manufacturing development and scale-up, including manufacturing registration and validation batches of tesetaxel; (iv) clinical and quality systems; and (v) regulatory submissions. Personnel-related expense includes expense related to salaries, benefits and equity-based compensation for personnel engaged in research and development functions.

Research and development expense is charged to operations as incurred when the expenditures relate to our research and development efforts and have no alternative future use. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received.

All of our research and development expense incurred to date has been incurred in connection with the development of tesetaxel. We do not expect our research and development expense to change significantly in the near term.

General and Administrative Expense

General and administrative expense includes non-personnel and personnel-related expense. Non-personnel-related expense includes expense related to: (i) professional fees for legal, patent, consulting, accounting and audit services; (ii) facilities and information technology; and (iii) insurance. Personnel-related expense includes expense related to salaries, benefits and equity-based compensation for personnel engaged in finance and administrative functions. We do not expect our general and administrative expense to change significantly in the near term.

Other Income, Net

Other income, net consists primarily of interest income generated from cash held in savings accounts. Other income, net also includes losses on disposal of property and equipment and gains and losses on foreign currency transactions.

Other income, net was $0.2 million and $0.9 million for the three and nine months ended September 30, 2020, respectively, compared to $1.1 million and $2.2 million, respectively, for the same periods in 2019. The decrease in other income, net was due primarily to decreased interest income.

Liquidity and Capital Resources

On September 1, 2020, we closed an underwritten public offering of 5,614,036 shares of common stock at a public offering price of $14.25 per share (collectively with the underwriters’ option, the “September 2020 Offering”). The underwriters exercised in full their option to purchase 842,105 additional shares of common stock. The aggregate gross proceeds from the September 2020 Offering were $92.0

18

million, and the net proceeds were $87.4 million after deducting underwriting discounts and commissions and offering costs.

As of September 30, 2020 and December 31, 2019, we had cash in the amount of $188.3 million and $180.5 million, respectively. We believe that our existing cash will be sufficient to meet our anticipated cash requirements through at least one year from the date this Quarterly Report on Form 10-Q is filed with the U.S. Securities and Exchange Commission (the “SEC”).

We have incurred losses in each year since our inception. Our net loss was $30.5 million and $94.1 million for the three and nine months ended September 30, 2020, respectively, compared to $26.6 million and $84.0 million, respectively, for the same periods in 2019. As of September 30, 2020 and December 31, 2019, we had an accumulated deficit of $334.1 million and $240.1 million, respectively. Substantially all of our operating losses resulted from expenses incurred in connection with advancing tesetaxel through development activities and general and administrative costs associated with our operations.

To date, we have funded our operations through the sale of equity securities. Since our inception, we have raised $466.9 million in net proceeds from the sale of equity securities.

The following table summarizes our net cash flow activity for each of the periods below (in thousands):

Net cash used in operating activities was $81.6 million and $72.1 million for the nine months ended September 30, 2020 and 2019, respectively. Net cash used in operating activities was primarily the result of our net loss and change in working capital, partially offset by equity-based compensation expense, depreciation expense and non-cash lease expense.

Net cash used in investing activities was $0.4 million and $0.2 million for the nine months ended September 30, 2020 and 2019, respectively. Net cash used in investing activities was the result of purchases of property and equipment.

Net cash provided by financing activities was $89.8 million and $137.5 million for the nine months ended September 30, 2020 and 2019, respectively. For the nine months ended September 30, 2020 and 2019, net cash provided by financing activities was primarily the result of net proceeds from the sale of common stock in underwritten public offerings.

Until such time as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic partnerships and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. 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. If we raise additional funds through collaborations, strategic partnerships or licensing arrangements with third parties, we may have to relinquish valuable rights to our product candidates, associated intellectual property, our other technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to us. If we are unable to raise

19

additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market our product candidate even if we would otherwise prefer to develop and market such product candidate ourselves.

Impact of the COVID-19 Pandemic

Although the ongoing Coronavirus Disease 2019 (“COVID-19”) pandemic did not have a material impact on our results of operations, financial condition or clinical studies during the nine months ended September 30, 2020, we are unable to accurately predict the full impact that the COVID-19 pandemic will have on our business in the future due to numerous factors that are not within our control, including its duration and severity.

Contractual Obligations and Commitments

In March 2018, we entered into an agreement to lease office space in San Diego, California (the “San Diego Lease”) with aggregate payments of approximately $0.8 million over the term of the lease. The San Diego Lease originally provided for expiration on December 31, 2019. In August 2019, the Company entered into a First Amendment to the San Diego Lease to extend the term of the lease through the commencement of the New San Diego Lease (defined below).

In October 2019, we entered into an agreement to lease office space in San Diego, California (the “New San Diego Lease”) with aggregate payments of approximately $4.1 million over the 7.5-year term of the lease. The New San Diego Lease commenced in July 2020. We have an option to extend the New San Diego Lease for an additional 5 years at the end of the initial term. Further, we provided a standby letter of credit of $0.5 million as a security deposit during the term of the lease, subject to certain reductions beginning 4 years after the lease commencement. As of September 30, 2020, $0.5 million was pledged as collateral for the letter of credit and recorded as restricted cash.

In February 2018, we entered into an agreement to lease office space in New York, New York (the “New York Lease”) with aggregate payments of approximately $2.8 million over the 7-year term of the lease. We have an option to extend the New York Lease for an additional three years at the end of the initial term. Further, we provided a standby letter of credit of $0.3 million in lieu of a security deposit during the term of the lease, subject to a reduction 3.5 years after the lease commencement. As of September 30, 2020, $0.3 million was pledged as collateral for the letter of credit and was recorded as restricted cash.

We enter into contracts in the normal course of business with contract development and manufacturing organizations and other service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments.

In 2013, we licensed rights to tesetaxel in all major markets from Daiichi Sankyo Company, Limited (“Daiichi Sankyo”), the original inventor of the product. Under the Daiichi Sankyo license agreement, we are obligated to use commercially reasonable efforts to develop and commercialize tesetaxel in the following countries: France, Germany, Italy, Spain, the United Kingdom and the U.S. We are required to make aggregate future milestone payments of up to $31.0 million, contingent on attainment of certain regulatory milestones. Additionally, we are obligated to pay Daiichi Sankyo a tiered royalty that ranges from the low- to high-single digits, depending on annual net sales of tesetaxel.

Off–Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any off–balance sheet arrangements as defined under the rules of the SEC.

20

Jumpstart Our Business Startups Act

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under this act, an emerging growth company can delay the adoption of new or revised accounting standards issued subsequent to the enactment of the JOBS Act until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. However, we intend to rely on other exemptions provided by the JOBS Act, including without limitation, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended. We will remain an emerging growth company until December 31, 2023 unless, prior to that time, we: (i) have more than $1.07 billion in annual gross revenue; (ii) have a market value for our common stock held by non-affiliates of more than $700 million as of the last day of our second quarter of any year; or (iii) issue more than $1.0 billion of non-convertible debt over a three-year period.

Critical Accounting Policies and Significant Judgments and Estimates

We believe the estimates, assumptions and judgments involved in the accounting policies described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2019 are most critical to understanding and evaluating our reported financial results. During the nine months ended September 30, 2020, there were no changes to our critical accounting policies and estimates as described in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2019.

Recent Accounting Pronouncements

See Note 2 to our condensed financial statements included in Item 1 of this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are a smaller reporting company, as defined by Rule 12b-2 under the Securities and Exchange Act of 1934 and in Item 10(f)(1) of Regulation S-K, and are not required to provide the information under this item.

Item 4. Controls and Procedures

Management’s Evaluation of our Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures. Based on that evaluation of our disclosure controls and procedures as of September 30, 2020, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such date are effective at the reasonable assurance level. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, 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 our

21

management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during our most recent quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may become subject to claims and litigation arising in the ordinary course of business. Other than as described below, we are not a party to any material legal proceedings, nor are we aware of any material pending or threatened litigation.

On September 16, 2020, a putative class action lawsuit was filed against us and our Chief Executive Officer, as well as our current and former Chief Financial Officers. The complaint was filed in the United States District Court for the Southern District of California and alleges that we made material misrepresentations and omissions regarding the safety and tolerability of tesetaxel in our public statements in violation of federal securities laws. The lawsuit seeks damages allegedly sustained by the class and an award of plaintiffs’ costs and attorney fees. We believe the complaint is without merit, and we have substantive defenses to the claims of liability and damages. We plan to respond accordingly.

Item 1A. Risk Factors

Our business is subject to various risks, including those described in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019. There have been no material changes from the risk factors disclosed in Item 1A of our Annual Report on Form 10-K, except for the additional risk factor set forth below.

The ongoing COVID-19 pandemic may disrupt our operations and affect our ability to successfully conduct clinical studies.

We are unable to accurately predict the full impact that the ongoing Coronavirus Disease 2019 (“COVID-19”) pandemic will have on our results from operations, financial condition and clinical studies due to numerous factors that are not within our control, including its duration and severity. Stay-at-home orders, business closures, travel restrictions, supply chain disruptions and employee illness or quarantines could result in disruptions to our operations, which could adversely impact our results from operations and financial condition. In addition, the COVID-19 pandemic has resulted in ongoing volatility in financial markets. If our access to capital is restricted or associated borrowing costs increase as a result of developments in financial markets relating to the COVID-19 pandemic, our operations and financial condition could be adversely impacted.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

None.

Item 3. Defaults upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.
