DURECT CORPORATION

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

Nature of Operations

DURECT Corporation (the “Company”) was incorporated in the state of Delaware on February 6, 1998. The Company is a biopharmaceutical company committed to transforming the treatment of acute organ injury and chronic liver diseases by advancing novel and potentially lifesaving therapies based on its endogenous epigenetic regulator program. Larsucosterol (also known as DUR-928), the Company's lead drug candidate, binds to and inhibits the activity of DNA methyltransferases (DNMTs), epigenetic enzymes which are elevated and associated with hypermethylation found in alcohol-associated hepatitis (AH) patients. Larsucosterol is in clinical development for the potential treatment of AH, for which FDA has granted a Fast Track Designation; non-alcoholic steatohepatitis (NASH) is also being explored. In addition, POSIMIR® (bupivacaine solution) for infiltration use, a non-opioid analgesic utilizing the innovative SABER® platform technology, is FDA-approved and has been exclusively licensed to Innocoll Pharmaceuticals for commercialization in the United States. The Company also manufactures and sells osmotic pumps used in laboratory research, and manufactures certain excipients for certain clients for use as raw materials in their products.

Basis of Presentation

These condensed financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”), and therefore do not include all the information and footnotes necessary for a complete presentation of the Company’s results of operations, financial position and cash flows in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). The unaudited condensed financial statements reflect all adjustments (consisting only of normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the financial position at June 30, 2023, the operating results and comprehensive loss, and stockholders’ equity for the three and six months ended June 30, 2023 and 2022, and cash flows for the six months ended June 30, 2023 and 2022. The balance sheet as of December 31, 2022 has been derived from audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. These financial statements and notes should be read in conjunction with the Company’s audited financial statements and notes thereto, included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC.

The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal year.

Reverse Stock Split

On December 5, 2022, the Company effected a 1-for-10 reverse stock split of its outstanding common stock. The reverse stock split also affected our outstanding stock options, purchase rights and equity incentive plans and resulted in the shares underlying such instruments being reduced and the exercise price being increased proportionately.

For all financial statement periods presented, references to number of shares, net loss per share, stock price and exercise price have been conformed to reflect the effects of the Company’s 1-for-10 reverse stock split, effective December 5, 2022, unless otherwise specified herein.

Liquidity and Need to Raise Additional Capital

As of June 30, 2023, the Company had an accumulated deficit of $584.6 million as well as negative cash flows from operating activities. Presently, the Company does not have sufficient cash resources to meet its plans for the next twelve months following the issuance of these financial statements. The Company will continue to require substantial funds to continue research and development, including clinical trials of its product candidates. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern for a period of one year from the issuance of these financial statements. Management’s plans in order to meet its operating cash flow requirements include seeking additional collaborative agreements for certain of its programs as well as financing activities such as public offerings and private placements of its common stock, preferred stock offerings, issuances of debt and convertible debt instruments.

There are no assurances that such additional funding will be obtained and that the Company will succeed in its future operations. If the Company cannot successfully raise additional capital and implement its strategic development plan, its liquidity, financial condition and business prospects will be materially and adversely affected, and the Company may have to cease operations. As further described in Note 6, the Company classified the remaining balance of its term loan as a current liability on the Company’s balance sheet as of June 30, 2023 and December 31, 2022 due to recurring losses, liquidity concerns and a subjective acceleration clause in the Company’s Loan Agreement. These financial statements have been prepared on a going concern basis and do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary in the event the Company can no longer continue as a going concern.

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost determined on a first-in, first-out basis. The Company capitalizes inventories produced in preparation for product launches after receiving regulatory approval on a product. The Company may be required to expense previously capitalized inventory costs upon a change in management’s judgment due to new information that suggests that the inventory will not be saleable. If the Company is able to subsequently sell products made with raw materials that were previously written down, the Company will report an unusually high gross profit as there will be no or little associated cost of goods for these materials.

The Company’s inventories consisted of the following (in thousands):


	June 30, 2023		December 31, 2022

Raw materials	$	167	$	168
Work in process		1,008		1,151
Finished goods		1,087		794
Total inventories	$	2,262	$	2,113

Leases

ASC 842 requires the Company to recognize an operating lease right-of-use asset and corresponding operating lease liability for the Company’s leased properties. The Company’s operating lease right-of-use assets and liabilities are recognized under ASC 842 based on the present value of lease payments over the remaining lease term at the lease commencement date. In determining the net present value of lease payments, we estimate the incremental borrowing rate based on the information available, including remaining lease term. As of June 30, 2023, the weighted-average remaining lease term was 3.07 years for the Company’s leased properties.

Revenue Recognition

Product Revenue, Net

The Company manufactures and sells ALZET osmotic pumps used in laboratory research, and manufactures and sells certain excipients used by pharmaceutical companies as raw materials in certain of their products, including POSIMIR, a marketed animal health product and Methydur.

Revenues from product sales are recognized when the customer obtains control of the Company’s product, which occurs at a point in time, typically upon shipment to the customer. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that the Company would have recognized is one year or less.

Trade Discounts and Allowances: The Company provides certain customers with discounts that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized.

Product Returns: The Company generally offers customers a limited right of return for products that have been purchased. The Company estimates the amount of its product sales that are probable of being returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities primarily using its historical sales information. The Company expects product returns to be minimal.

Collaborative Research and Development and Other Revenue

The Company enters into license agreements, under which it licenses certain rights to its product candidates or products to third parties. The terms of these arrangements typically include payment to the Company of one or more of the following: non-refundable, up-front license fees; reimbursement of development costs incurred by the Company under approved work plans; development, regulatory, intellectual property and commercial milestone payments; payments for manufacturing supply services the Company provides itself or through its contract manufacturers; and royalties on net sales of licensed products. Each of these payments results in collaborative research and development revenues, except for revenues from royalties on net sales of licensed products and earn-out revenues, which are classified as other revenues.

In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. For arrangements that are determined to include multiple performance obligations, the Company must develop assumptions that require judgment to determine the estimated stand-alone selling price for each performance obligation identified. These assumptions may include: forecasted revenues, development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success. The Company expects to recognize revenue for the variable consideration currently being constrained when it is probable that a significant revenue reversal will not occur.

Licenses of intellectual property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from the transaction price allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. For performance obligations comprised of licenses that are bundled with other promises, the Company utilizes its judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the Company applies an appropriate method of measuring progress for purposes of recognizing related revenues from the allocated transaction price. For performance obligations recognized over time, the Company evaluates the measure of progress each reporting period and recognizes revenues on a cumulative catch-up basis as collaborative research and development revenues.

Milestone Payments: At the inception of each arrangement that includes development milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint, and if necessary, adjusts its estimate of the overall transaction price.

Manufacturing Supply Services: Arrangements that include a promise for future supply of raw materials or drug product for either clinical development or commercial supply at the customer’s discretion are generally considered as options. The Company assesses if these options provide a material right to the customer and if so, they are accounted for as separate performance obligations and allocated a portion of the transaction price based on the estimated standalone selling price of the material right. If the Company is entitled to additional payments when the customer exercises these options, the deferred transaction price and any additional payments are recorded in collaborative research and development revenue when the customer obtains control of the goods.

Royalties and Earn-outs: For arrangements that include sales-based royalties or earn-outs, including milestone payments based on first commercial sale or the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized material royalty revenue resulting from the Company’s collaborative arrangements or material earn-out revenues from any of the Company’s agreements.

Research and development services: Revenue from research and development services that are determined to represent a distinct performance obligation with the Company’s third-party collaborators is recognized over time as the related research and development services are performed using an appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and recognizes revenue on a cumulative catch-up basis, as collaborative research and development revenue. Research and development expenses under the collaborative research and development agreements generally approximate or exceed the revenue recognized under such agreements over the term of the respective agreements. Deferred revenue may result when the Company does not expend the required level of effort during a specific period in comparison to funds received under the respective agreement.

The Company receives payments from its customers based on development cost schedules established in each contract. Up-front payments are recorded as deferred revenue upon receipt or when due and may require deferral of revenue recognition to a future period until the Company performs its obligations under these arrangements. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional. The Company does not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

Total revenue by geographic region based on customers’ locations for the three and six months ended June 30, 2023 and 2022 are as follows (in thousands):

Prepaid and Accrued Clinical Costs

The Company incurs significant costs associated with third party consultants and organizations for pre-clinical studies, clinical trials, contract research, regulatory advice and other research and development-related services. The Company is required to estimate periodically the cost of services rendered but unbilled based on management’s estimates. Estimates are determined each reporting period by reviewing the terms and conditions of the underlying contracts, reviewing open purchase orders and by having detailed discussions with internal clinical personnel and third-party service providers as to the nature and status of the services performed in relation to amounts billed. The costs for unbilled services are estimated by applying the rates and fees applicable in the underlying contracts. If these good faith estimates are inaccurate, actual expenses incurred could materially differ from these estimates

Prepaid and Accrued Manufacturing Costs

The Company incurs significant costs associated with third party consultants and organizations for manufacturing, validation, testing and other research and development-related services. The Company is required to estimate periodically the cost of services rendered but unbilled based on management’s estimates. Estimates are determined each reporting period by reviewing the terms and conditions of the underlying contracts, reviewing open purchase orders and by having detailed discussions with internal personnel and third-party service providers as to the nature and status of the services performed in relation to amounts billed. The costs for unbilled services are estimated by applying the rates and fees applicable in the underlying contracts. If these good faith estimates are inaccurate, actual expenses incurred could materially differ from these estimates.

Research and development expenses

Research and development expenses are primarily comprised of salaries and benefits associated with research and development personnel, overhead and facility costs, preclinical and non-clinical development costs, clinical trial and related clinical manufacturing costs, contract services, and other outside costs. Research and development costs are expensed as incurred. Research and development costs paid to third parties under sponsored research agreements are recognized as the related services are performed. In addition, research and development expenses incurred that are reimbursed by the Company’s partners are recorded as collaborative research and development revenue.

Comprehensive Loss

Components of other comprehensive loss are comprised entirely of unrealized gains and losses on the Company’s available-for-sale securities for all periods presented. Total comprehensive loss has been disclosed in the Company’s Statements of Operations and Comprehensive Loss.

Common Stock Warrants

The Company reviews the terms of debt instruments, equity instruments, and other financing arrangements to determine whether there are embedded derivative features, including embedded conversion options that are required to be bifurcated and accounted for separately as a derivative financial instrument. Additionally, in connection with the issuance of financing instruments, the Company may issue freestanding options and warrants.

The Company accounts for its common stock warrants in accordance with ASC 480, Distinguishing Liabilities from Equity ("ASC 480") and ASC 815, Derivatives and Hedging (“ASC 815”). Based upon the provisions of ASC 480 and ASC 815, the Company accounts for common stock warrants and pre-funded warrants as current liabilities if the warrant fails the equity classification criteria. Common stock warrants and pre-funded warrants classified as liabilities are initially recorded at fair value on the grant date and remeasured at each balance sheet date with the offsetting adjustments recorded in change in fair value of warrant liabilities within the statements of operations.

The Company values its pre-funded warrants and common stock warrants classified as liabilities using the Black-Scholes option pricing model or other acceptable valuation models, including the Monte-Carlo simulation model.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding. Diluted net loss per share is computed using the weighted-average number of common shares outstanding and common stock equivalents (i.e., options to purchase common stock) outstanding during the period, if dilutive, using the treasury stock method for options.

The numerators and denominators in the calculation of basic and diluted net loss per share were as follows (in thousands except per share amounts):


	Three months ended June 30,						Six months ended June 30,
	2023			2022			2023			2022
Basic loss per share computation:
Net loss	$	(11,181	)	$	(11,551	)	$	(23,168	)	$	(22,393	)
Weighted average number of shares outstanding - basic		24,508			22,774			24,140			22,771
Net loss per share - basic	$	(0.46	)	$	(0.51	)	$	(0.96	)	$	(0.98	)

Diluted loss per share computation:
Net loss	$	(11,181	)	$	(11,551	)	$	(23,168	)	$	(22,393	)
Change in fair value of warrant liabilities		—			—			258			—
Net loss adjusted for change in fair value of warrant liabilities	$	(11,181	)	$	(11,551	)	$	(23,426	)	$	(22,393	)

Weighted average shares used to compute basic net loss per share		24,508			22,774			24,140			22,771
Dilutive effect of pre-funded warrants		—			—			237			—
Weighted average shares used to compute diluted net loss per share		24,508			22,774			24,377			22,771
Net loss per share - diluted	$	(0.46	)	$	(0.51	)	$	(0.96	)	$	(0.98	)

Options to purchase approximately 3.1 million and 3.0 million shares of common stock were excluded from the denominator in the calculation of diluted net loss share for the three and six months ended June 30, 2023, respectively, as the effect would be anti-dilutive. Options to purchase approximately 2.79 million and 2.62 million shares of common stock were excluded from the denominator in the calculation of diluted net loss share for the three and six months ended June 30, 2022, respectively, as the effect would be anti-dilutive. In addition, the dilutive effect of pre-funded warrants was 237,000 shares for the six months ended June 30, 2023. Pre-funded warrants to purchase 300,000 shares were also outstanding during the three months ended June 30, 2023, but were not included in the computation of diluted net loss per share for the three months ended June 30, 2023 because the effect would be anti-dilutive. Additional common warrants to purchase 2.0 million and 1.6 million shares were also outstanding during the three and six months ended June 30, 2023, but were not included in the computation of diluted net loss per share because the effect would be anti-dilutive.

Recently Adopted Accounting Pronouncements

In August 2020, FASB issued Accounting Standards Update ("ASU") 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) — Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity ("ASU- 2020-06"), which, among other things, provides guidance on how to account for contracts on an entity’s own equity. This ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, the ASU eliminated the need for the Company to assess whether a contract on the entity’s own equity (1) permits settlement in unregistered shares, (2) whether counterparty rights rank higher stockholder’s rights, and (3) whether collateral is required. In addition, the ASU requires incremental disclosure related to contracts on the entity’s own equity and clarifies the treatment of certain financial instruments accounted for under this ASU on earnings per share. This ASU may be applied on a full retrospective of modified retrospective basis. For smaller reporting companies, this ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption of the ASU is permitted for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company early adopted this standard on January 1, 2023 and the adoption did not have any effect on the financial statements as the Company did not have any such outstanding instruments as of January 1, 2023.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13 (ASU 2016-13) “Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets. This standard is effective for fiscal years beginning after December 15, 2022 for small reporting companies, including interim reporting periods within those years and must be adopted using a modified retrospective approach, with certain exceptions. Early adoption is permitted. The Company adopted the standard on January 1, 2023 and the adoption did not have a material effect on the financial statements.

Note 2. Strategic Agreements

The collaborative research and development and other revenues associated with the Company’s collaborators or counterparties were $508,000 and $1.2 million for the three and six months ended June 30, 2023, compared with $606,000 and $1.1 million for the corresponding periods in 2022, respectively. The collaborative research and development and other revenue included (a) amounts related to earn-out revenue from Indivior UK Limited ("Indivior") with respect to PERSERIS net sales; (b) feasibility programs and

research and development activities funded by our collaborators and (c) royalty revenue from Orient Pharma Co., Ltd. (“Orient Pharma”) with respect to Methydur net sales.

Agreement with Innocoll

On December 21, 2021, the Company entered into a license agreement (the “Innocoll Agreement”) with Innocoll Pharmaceuticals Limited (“Innocoll”). Pursuant to the Innocoll Agreement, the Company has granted Innocoll an exclusive, royalty-bearing, sublicensable right and license to develop, manufacture and commercialize in the United States, POSIMIR®, the Company’s FDA-approved post-surgical pain product, with respect to all uses and applications in humans. The Innocoll Agreement provides for the assignment of the Company’s supply agreement with its contract manufacturing organization to Innocoll and also provides Innocoll with the right, within the United States, to expand the approved indications of POSIMIR. The Company retains, outside the United States, all of the global rights to POSIMIR.

Upon execution of the Innocoll Agreement, Innocoll paid the Company an initial nonrefundable, upfront fee of $4.0 million as well as a fee in the amount of $1.3 million primarily to cover the manufacturing supplies and excipients and certain equipment transferred to Innocoll pursuant to the terms of the Innocoll Agreement, and certain recently incurred DURECT expenses the parties negotiated for Innocoll to reimburse. The Innocoll Agreement includes customary representations and warranties on behalf of the Company and Innocoll, including representations as to the licensed intellectual property, regulatory matters and compliance with applicable laws. The Innocoll Agreement also provides for certain mutual indemnities for breaches of representations, warranties and covenants.

The Company also evaluated Innocoll’s future purchases of an excipient from the Company and concluded that these purchases are option rights, and are at market rates, and do not constitute a material right performance obligation. As such, these future purchases have been excluded from the allocation of transaction price and the Company will account for them as separate contracts when and if Innocoll elects to issue purchase orders for the excipient.

During December 2021, the upfront fee of $4.0 million as well as a fee in the amount of $1.2 million to cover reimbursed expenses, the manufacturing supplies and excipients transferred to Innocoll pursuant to the terms of the Innocoll Agreement was recognized as revenue when the performance obligations were satisfied in December 2021 and $0.1 million was recorded as a net reduction in equipment in December 2021. At December 31, 2021, the Company included $5.3 million due from Innocoll in accounts receivable on its balance sheet; these funds were received in January 2022.

In August 2022, the Company was issued a new patent by the U.S. Patent and Trademark Office, extending U.S. patent coverage of POSIMIR to at least 2041, resulting in an $8.0 million milestone payment by Innocoll to the Company. In September 2022, Innocoll launched POSIMIR in the U.S., triggering a $2.0 million milestone payment to the Company for the first commercial sale of POSIMIR. Thus, the Company recognized $10.0 million of milestone revenue under the agreement with Innocoll during the twelve months ended December 31, 2022. As the commercial launch of POSIMIR progresses, the Company will receive tiered, low double-digit to mid-teen royalties on net product sales of POSIMIR in the United States. The Company may earn additional milestone payments of up to $122.0 million in the aggregate, depending on the achievement of certain regulatory, commercial, and intellectual property milestones with respect to POSIMIR.

Patent Purchase Agreement with Indivior

In September 2017, we entered into an agreement with Indivior (the “Indivior Agreement”), under which we assigned to Indivior certain patents that may provide further intellectual property protection for PERSERIS, Indivior’s extended-release injectable suspension for the treatment of schizophrenia in adults. In consideration for such assignment, Indivior made non-refundable upfront and milestone payments to DURECT totaling $17.5 million. Additionally, under the terms of the agreement with Indivior, DURECT receives quarterly earn-out payments into 2026 that are based on a single digit percentage of U.S. net sales of PERSERIS. Indivior commercially launched PERSERIS in the U.S. in February 2019. The Indivior Agreement contains customary representations, warranties and indemnities of the parties. Amounts recognized during the three and six months ended June 30, 2023 and 2022 related to earn-out revenues from PERSERIS have been immaterial and are included in collaborative research and development and other revenue.

Note 3. Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company’s valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company follows a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. These levels of inputs are the following:

•

Level 1—Quoted prices in active markets for identical assets or liabilities.

•

Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company’s financial instruments are valued using quoted prices in active markets or based upon other observable inputs. Money market funds are classified as Level 1 financial assets. Certificates of deposit, commercial paper, municipal bonds, corporate debt securities, and U.S. Government agency securities are classified as Level 2 financial assets. The fair value of the Level 2 assets is estimated using pricing models using current observable market information for similar securities. The Company’s Level 2 investments include U.S. government-backed securities and corporate securities that are valued based upon observable inputs that may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications. The fair value of commercial paper is based upon the time to maturity and discounted using the three-month treasury bill rate. The average remaining maturity of the Company’s Level 2 investments as of June 30, 2023 is less than twelve months and these investments are rated by S&P and Moody’s at AAA or AA- for securities and A1, A2, P1 or P2 for commercial paper.

	$	31,939	$	31,933

There were no securities that have had an unrealized loss for more than 12 months as of June 30, 2023.

As of June 30, 2023, unrealized losses on available-for-sale investments are not attributed to credit risk and are considered to be temporary. The Company believes that it is more-likely-than-not that investments in an unrealized loss position will be held until maturity or the recovery of the cost basis of the investment. To date, the Company has not recorded any impairment charges on marketable securities related to other-than-temporary declines in market value.

Warrant Liabilities

In February 2023, the Company issued pre-funded warrants to purchase 300,000 shares of common stock and common warrants to purchase an aggregate of 2,000,000 shares of common stock in a registered direct offering.

The pre-funded warrants are accounted for as current liabilities on the balance sheet and are adjusted to estimated fair value at period end through “other income (expense)” on the statement of operations. The estimated fair value of the pre-funded warrants was $1.7 million, $1.4 million and $1.5 million as of February 8, 2023 (i.e., the issuance date), March 31, 2023 and June 30, 2023, respectively. The Company calculated the estimated fair value of the pre-funded warrants using a Black-Scholes option pricing model with the following key assumptions:


	2/8/2023 (issuance)			March 31, 2023			June 30, 2023
Common stock price	$	5.81		$	4.53		$	4.95
Exercise price per share	$	0.00001		$	0.00001		$	0.00001
Expected volatility		86.60	%		86.20	%		89.10	%
Risk-free interest rate		3.82	%		3.65	%		4.22	%
Contractual term (in years)		5.00			4.90			4.60
Expected dividend yield		—	%		—	%		—	%

The common warrants are accounted for as current liabilities on the balance sheet and are adjusted to fair value at period end through “other income (expense)” on the statement of operations. The estimated fair value of the common warrants was $10.3 million, $8.2 million and $9.0 million as of February 8, 2023 (i.e., the issuance date), March 31, 2023 and June 30, 2023, respectively. The Company calculated the fair value of the common warrants using a Monte Carlo simulation model with the following key assumptions. In all cases, the Company took the likelihood of achieving certain clinical events and related impact on the Company's common stock price into account.


	2/8/2023 (issuance)			March 31, 2023			June 30, 2023
Common stock price	$	5.81		$	4.53		$	4.95

Note 4. Accrued Liabilities

Accrued liabilities as of June 30, 2023 and December 31, 2022 were comprised as follows (in thousands):


	June 30, 2023		December 31, 2022

Accrued compensation and benefits	$	2,430	$	3,970
Accrued clinical costs		2,117		1,966
Accrued contract research and manufacturing costs		2,379		861
Others		853		1,099
Total	$	7,779	$	7,896

Note 5. Stock-Based Compensation

As of June 30, 2023, the Company has two stock-based compensation plans. The stock-based compensation cost that has been included in the statements of operations and comprehensive loss is shown as below (in thousands):


	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022
Cost of product revenues	$	5	$	5	$	9	$	10
Research and development		301		296		593		626
Selling, general and administrative		353		317		659		660
Total stock-based compensation	$	659	$	618	$	1,261	$	1,296

As of June 30, 2023 and December 31, 2022, $15,000 and $16,000 of stock-based compensation cost were capitalized in inventory on the Company’s balance sheets for each period, respectively.

The Company uses the Black-Scholes option pricing model to value its stock options. The expected life computation is based on historical exercise patterns and post-vesting termination behavior. The Company considered its historical volatility in developing its estimate of expected volatility.

The Company used the following assumptions to estimate the fair value of stock options granted and shares purchased under its employee stock purchase plan for the three and six months ended June 30, 2023 and 2022:


	Three months ended June 30,					Six months ended June 30,
	2023			2022		2023		2022

Note 6. Term Loan

In July 2016, the Company entered into a $20.0 million secured single-draw term loan (as amended, the “Loan Agreement”) with Oxford Finance LLC (“Oxford Finance”). The Company and Oxford Finance entered into five subsequent amendments to the Loan Agreement in February 2018, November 2018, December 2019, March 2021 and May 2021. For amendments 1-3 and 5, the Company paid Oxford Finance loan modification fees of $100,000, $900,000, $825,000 and $712,500, respectively. As amended, the Loan Agreement provides for interest only payments through June 1, 2023, followed by consecutive monthly payments of principal and interest in arrears starting on June 1, 2023 and continuing through the maturity date of the term loan of September 1, 2025. The Loan Agreement provides for a floating interest rate (7.95% initially and 12.55% as of June 30, 2023) based on an index rate plus a spread. In addition, a payment equal to 10% of the principal amount of the term loan is due when the term loan becomes due or upon the prepayment of the facility. If the Company elects to prepay the loan, there is also a prepayment fee of between 0.75% and 2.5% of the principal amount of the term loan depending on the timing of prepayment. The $150,000 facility fee that was paid at the original closing, the loan modification fees and other debt offering/issuance costs have been recorded as debt discount on the Company’s balance sheets and together with the final $2.0 million payment are being amortized to interest expense using the effective interest method over the revised term of the loan.

The term loan is secured by substantially all of the assets of the Company, except that the collateral does not include any intellectual property (including licensing, collaboration and similar agreements relating thereto), and certain other excluded assets. The Loan Agreement contains customary representations, warranties and covenants by the Company, which covenants limit the Company’s ability to convey, sell, lease, transfer, assign or otherwise dispose of certain assets of the Company; engage in any business other than the businesses currently engaged in by the Company or reasonably related thereto; liquidate or dissolve; make certain management changes; undergo certain change of control events; create, incur, assume, or be liable with respect to certain

indebtedness; grant certain liens; pay dividends and make certain other restricted payments; make certain investments; and make payments on any subordinated debt.

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, the Company’s failure to fulfill certain obligations of the Company under the Loan Agreement and the occurrence of a material adverse change which is defined as a material adverse change in the Company’s business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of any portion of the loan, or a material impairment in the perfection or priority of lender’s lien in the collateral or in the value of such collateral. In the event of default by the Company under the Loan Agreement, the lender would be entitled to exercise its remedies thereunder, including the right to accelerate the debt, upon which the Company may be required to repay all amounts then outstanding under the Loan Agreement, which could harm the Company’s financial condition. The conditionally exercisable call option related to the event of default is considered to be an embedded derivative which is required to be bifurcated and accounted for as a separate financial instrument. In the periods presented, the value of the embedded derivative is not material, but could become material in future periods if an event of default became more probable than is currently estimated.

As of June 30, 2023, the Company was in compliance with all material covenants under the Loan Agreement and there had been no material adverse change. In accordance with ASC 470-10-45-2, the term loan was classified as a current liability on the Company’s balance sheet as of June 30, 2023 and December 31, 2022 due to recurring losses, liquidity concerns and a subjective acceleration clause in the Company’s Loan Agreement.

The fair value of the term loan approximates the carrying value. Future maturities due under the term loan as of June 30, 2023, are as follows (in thousands):


Six months ended December 31, 2023	$	4,286
2024		8,571
2025		8,429
Total minimum payments		21,286

Note 8. Stockholders’ Equity

In July 2021, the Company filed a shelf registration statement on Form S-3 with the SEC (the “2021 Registration Statement”) (File No. 333-258333), which upon being declared effective in August 2021, allows the Company to offer up to $250.0 million of securities from time to time in one or more public offerings, inclusive of up to $75.0 million of shares of the Company’s common stock which the Company may sell, subject to certain limitations, pursuant to a sales agreement dated July 30, 2021 with Cantor Fitzgerald & Co. (the “2021 Sales Agreement”).

Registered Direct Offering

On February 3, 2023, the Company entered into a securities purchase agreement with two institutional investors relating to the purchase and sale of an aggregate of (i) 1,700,000 shares of its common stock, par value $0.0001 per share, (ii) pre-funded warrants to purchase 300,000 shares of common stock, and (iii) accompanying common warrants, to purchase an aggregate of 2,000,000 shares of Common Stock in a registered direct offering (the "offering"). The issuance date of the common stock, the pre-funded warrants and the accompanying common warrants was February 8, 2023. The aggregate gross proceeds to the Company from the offering were $10.0 million before deducting placement agent fees and other estimated offering expenses payable by the Company. The Company incurred offering costs of $1.2 million which were included in loss on issuance of warrants on the statement of operations for the three months ended March 31, 2023 and six months ended June 30, 2023. The aggregate net proceeds to the Company from the offering were approximately $8.8 million after deducting placement agent fees and other estimated offering expenses payable by us.

The pre-funded warrants were exercisable immediately following the closing date of the offering and have an unlimited term and an initial exercise price of $0.00001 per share. The common warrants were immediately exercisable and have a five year term and an initial exercise price of $5.00 per share. The combined offering price was $5.00 per share and accompanying common warrant, or in the case of pre-funded warrants, $4.99999 per pre-funded warrant and accompanying common warrant. A holder (together with its affiliates) may not exercise any portion of a pre-funded warrant or common warrant to the extent that the holder would own more than 4.99% (or, at the election of the holder 9.99%) of DURECT’s outstanding common stock immediately after exercise.

The Company accounts for the pre-funded warrants and the common warrants as current liabilities based upon the guidance of ASC 480 and ASC 815. The Company evaluated the common and pre-funded warrants under ASC 815-40, Derivatives and Hedging—Contracts in Entity’s Own Equity (“ASC 815-40”), and concluded that they do not meet the criteria to be classified in stockholders’ equity. Specifically, the exercise of the pre-funded warrants could be settled in cash upon the occurrence of a tender offer or exchange that involves 50% or more of the Company’s common stock. Because a change of 50% or more of the Company’s common stock may not result in a change in control of the Company, the Company believes that the scope exception related to the occurrence of a fundamental transaction in ASC 815-40 is not met. The common warrants have the same characteristics as the pre-funded warrants related to the occurrence of a fundamental transaction, therefore the common warrants are also precluded from equity classification. In addition, the holder of the common warrants is permitted to receive the highest volume weighted average price ("VWAP") from the date of announcement of the fundamental transaction through the date the holder provides notice of repurchase, as a way to protect the holder against reductions in the stock price in a fundamental transaction, while allowing the holder to keep the benefits of an upside, which precludes the common warrants from being considered indexed to the Company’s stock. Since the common and pre-funded warrants meet the definition of derivatives under ASC 815, the Company records these warrants as current liabilities on the balance sheet at fair value, with subsequent changes in their respective fair values recognized in the statement of operations and comprehensive loss at each reporting date.

Estimating fair values of liability-classified financial instruments requires the development of estimates that may, and are likely to, change over the duration of the instrument with related changes in internal and external market factors. In addition, option-based techniques are highly volatile and sensitive to changes in the trading market price of the Company’s common stock. Because liability-classified financial instruments are initially and subsequently carried at fair value, the Company’s financial results will reflect the volatility in these estimate and assumption changes. Changes in fair value are recognized as a component of other income (expense) in the statement of operations.

At the date of issuance, the Company valued the common warrants using a Monte-Carlo valuation model with a fair value of $10.3 million and valued the pre-funded warrants using the Black-Scholes option valuation model with a fair value of $1.7 million. Since the fair value of the warrants at issuance was greater than the gross proceeds of $10.0 million received, the Company recorded approximately $2.0 million (i.e., the difference of the fair value of the warrants and the gross proceeds received) as a loss on issuance of warrants on the statement of operations at issuance.

At June 30, 2023, the Company re-valued the common warrants using a Monte-Carlo valuation model with a fair value of $9.0 million, an increase of $766,000 from March 31, 2023; and re-valued the pre-funded warrants using the Black-Scholes option valuation model with a fair value of $1.5 million, an increase of $126,000 from June 30, 2023. The loss of $892,000 resulting from the change in the fair value of the liability for the warrants was recorded as a change in fair value of warrant liabilities in the accompanying statements of operations for the three months ended June 30, 2023. The gain of $1.6 million resulting from the change in the fair value of the liability for the warrants was recorded as a change in fair value of warrant liabilities in the accompanying statements of operations for the six months ended June 30, 2023. As of June 30, 2023, none of the warrants have been exercised.

The common warrant liability and the pre-funded warrant liability will be adjusted to fair value at each balance sheet date until the warrants are settled. Changes in fair value of the warrant liabilities are recognized as a component of other income (expense), net in the statement of operations and comprehensive loss.

The Company also allocated the offering expenses of $1.2 million to warrant liabilities and expensed (within other expense, net) $1.2 million upon the closing of the offering.

ATM Financings

During the three and six months ended June 30, 2023, the Company raised net proceeds (net of commissions) of approximately $658,000 from the sale of 118,132 shares of the Company’s common stock in the open market at a weighted average price of $5.68 per share pursuant to the 2021 Registration Statement and the 2021 Sales Agreement.

As of August 7, 2023, the Company had up to $224.3 million of the Company’s securities available for sale under the 2021 Registration Statement, of which $74.3 million of the Company’s common stock are available pursuant to the 2021 Sales Agreement.

Note 9. Subsequent Events

In July 2023, the Company sold 2,991,027 shares of common stock and accompanying warrants to purchase up to 2,991,027 shares of common stock in a registered direct offering priced at-the-market under Nasdaq rules. The shares of common stock and accompanying warrants were sold at a combined purchase price of $5.015 per share and accompanying warrant. The warrants have an exercise price of $4.89 per share, are immediately exercisable and will expire five years from the date of issuance. The net proceeds from the offering to the Company were approximately $13.8 million after deducting placement agent fees and other estimated offering expenses.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations for the three and six months ended June 30, 2023 should be read in conjunction with (i) our unaudited condensed financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and (ii) our annual report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”) as well as Part I, Item 1A., “Risk Factors” section included therein and any additional risk factors that may be described herein or in our subsequent reports filed with the SEC. References to the “Company,” “DURECT,” “we,” “us” and “our” refer to DURECT Corporation.

Overview

We are a biopharmaceutical company advancing novel and potentially lifesaving investigational therapies derived from our Epigenetic Regulator Program. Larsucosterol (also known as “DUR‑928”), a new chemical entity in clinical development, is the lead candidate in our Epigenetic Regulator Program. An endogenous, orally bioavailable small molecule, larsucosterol has been shown in both in vitro and in vivo studies to play an important regulatory role in lipid metabolism, stress and inflammatory responses, and cell death and survival. We are developing larsucosterol for alcohol-associated hepatitis (“AH”), a life-threatening acute liver condition with no approved therapeutics and a 28-Day and 90-Day historical mortality rate of 20%-26% and 29%-31%, respectively. After completing a Phase 2a trial in which 100% of AH patients treated with larsucosterol survived the 28-Day study period, we are now conducting a double-blind, placebo-controlled Phase 2b clinical trial called AHFIRM (trial in AH to evaluate saFety and effIcacy of laRsucosterol treatMent). Through our AHFIRM trial, we are evaluating larsucosterol’s potential to reduce mortality or liver transplantation compared to a placebo with or without steroids at the investigators’ discretion. In June 2023 we announced that we had completed enrollment in the AHFIRM trial. In total, we randomized and dosed 301 patients at leading hospitals in the U.S., Australia, E.U. and U.K., including prominent transplant centers. We anticipate reporting topline results in the fourth quarter of 2023. If the AHFIRM trial is successful, we plan to review the results with the U.S. Food and Drug Administration (FDA) in the first quarter of 2024. We believe a positive outcome in the AHFIRM trial could support a New Drug Application (“NDA”) filing, and, if larsucosterol is approved, we may decide to develop our own commercial, sales and marketing organization. We have also investigated larsucosterol in patients with non-alcoholic steatohepatitis with encouraging results in a Phase 1b clinical trial and are considering further development of larsucosterol for this and other indications.

Building on our knowledge of epigenetic modulation, DURECT has internally developed multiple novel small molecule DNMT inhibitors that exhibit broad spectrum activity against multiple hematologic and solid tumor types. These compounds display unique and desirable physiochemical properties and pharmacokinetic profiles, as well as favorable tolerability. We intend to select a product candidate by the end of 2023 to advance into clinical trials in cancer patients. Our goal is to be prepared to initiate clinical trials for this product candidate by the end of 2024.

In addition to our Epigenetic Regulator Program, we developed a novel and proprietary post-surgical pain product called POSIMIR that utilizes our innovative SABER® platform technology to enable continuous sustained delivery of bupivacaine, a non-opioid local analgesic, over three days in adults. In February 2021, POSIMIR received U.S. FDA approval for post-surgical pain reduction for up to 72 hours following arthroscopic subacromial decompression. In December 2021, we entered into a license agreement with Innocoll Pharmaceuticals Limited (“Innocoll”), pursuant to which the Company granted to Innocoll an exclusive, royalty-bearing, sublicensable right and license to develop, manufacture and commercialize POSIMIR in the United States. In September 2022, Innocoll launched POSIMIR in the U.S.

As a result of the assignment of certain patent rights, we also receive single digit sales-based earn-out payments from U.S. net sales of Indivior UK Limited’s PERSERIS® (risperidone) drug for schizophrenia and single-digit royalties from net sales of Orient Pharma Co., Ltd.’s Methydur Sustained Release Capsules (“Methydur”) for the treatment of attention deficit hyperactivity disorder in Taiwan. We also manufacture and sell ALZET® osmotic pumps used in laboratory research.

NOTE: POSIMIR® is a trademark of Innocoll Pharmaceuticals, Ltd. in the U.S. and a trademark of DURECT Corporation outside of the U.S. SABER® and ALZET® are trademarks of DURECT Corporation. Other trademarks referred to belong to their respective owners. Full prescribing information for POSIMIR, including BOXED WARNING and Medication Guide can be found at www.posimir.com. Full prescribing information for PERSERIS, including BOXED WARNING and Medication Guide can be found at www.perseris.com.

Collaborative Research and Development and Other Revenue

Collaborative research and development and other revenue consists of three broad categories: (a) the recognition of upfront license payments over the period of our continuing involvement with the third party, (b) the reimbursement of qualified research expenses by third parties, (c) milestone payments in connection with our collaborative agreements and (d) royalties and earn out payments from our agreements with third parties. During the last two years, we generated collaborative research and development revenues from collaborative agreements with Innocoll and others.

Product Revenues

We also currently generate product revenue from the sale of two product lines:

•

ALZET® osmotic pumps which are used for animal research; and

•

certain key excipients that are included in Methydur and one excipient that is included in POSIMIR and in a marketed animal health product.

Because we consider our core business to be developing and commercializing pharmaceuticals, we do not intend to significantly increase our investments in or efforts to sell or market any of our existing product lines.

Operating Results

Since our inception in 1998, we have generally had a history of operating losses. At June 30, 2023, we had an accumulated deficit of $584.6 million. Our net losses were $11.2 million and $23.2 million for the three and six months ended June 30, 2023 compared with $11.6 million and $22.4 million for the corresponding periods in 2022. These losses have resulted primarily from costs incurred to research and develop our product candidates and to a lesser extent, from selling, general and administrative costs associated with our operations and product sales. We expect our research and development expenses in the near future to remain comparable to the second quarter of 2023 as we continue to incur research and development expenses related to larsucosterol. We expect our selling, general and administrative expenses in the near future to be comparable to the second quarter of 2023. We expect to incur continuing losses and negative cash flows from operations for the foreseeable future.

Critical Accounting Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The most significant estimates and assumptions relate to revenue recognition, prepaid and accrued contract research expenses, and stock-based compensation. Actual amounts could differ significantly from these estimates. There have been no material changes to our other critical accounting estimates as compared to the disclosures in our annual report on Form 10-K for the year ended December 31, 2022.

Results of Operations

Three and six months ended June 30, 2023 and 2022

Collaborative research and development and other revenue

We recognize revenue from collaborative research and development activities and service contracts. Collaborative research and development and other revenue primarily represents reimbursement of qualified expenses related to collaborative agreements with various third parties to research, develop and commercialize potential products using our drug delivery technologies, and revenue from the recognition of upfront fees and milestone payments in connection with our collaborative or license agreements.

We expect our collaborative research and development and other revenue to fluctuate in future periods pending our efforts to enter into potential new collaborations, and any royalty or earn-out revenue recognized from collaborators or counterparties.

The collaborative research and development and other revenue associated with our major collaborators or counterparties were $508,000 and $1.2 million for the three and six months ended June 30, 2023 compared with $606,000 and $1.1 million for the corresponding periods in 2022. The collaborative research and development and other revenue included (a) amounts related to earn-out revenue from Indivior UK Limited (Indivior) with respect to PERSERIS net sales; (b) feasibility programs and research and development activities funded by our collaborators and (c) royalty revenue from Orient Pharma with respect to Methydur net sales.

Product revenue

A portion of our revenues is derived from product sales, which include our ALZET osmotic pump product line and certain excipients that are included in POSIMIR, Methydur and in a marketed animal health product. Net product revenues were $1.6 million and $3.0 million for the three and six months ended June 30, 2023 compared with $1.5 million and $2.9 million for the corresponding periods in 2022. The increases in the three and six months ended June 30, 2023 were primarily attributable to higher revenue from our ALZET mini pump product line as a result of higher units sold, partially offset by lower revenue from certain excipients that are included in Methydur and in an animal health product compared to the corresponding periods in 2022.

Cost of product revenues

Cost of product revenues was $359,000 and $747,000 for the three and six months ended June 30, 2023 compared with $393,000 and $728,00 for the corresponding periods in 2022. Cost of product revenues in the three months ended June 30, 2023 decreased compared to the corresponding period in 2022 primarily due to lower manufacturing costs for units sold from our ALZET product line. Cost of product revenues in the six months ended June 30, 2023 increased compared to the corresponding periods in 2022 primarily due to higher units sold from our ALZET product line. Stock-based compensation expense recognized related to cost of product revenues was $5,000 and $9,000 for the three and six months ended June 30, 2023 compared to $5,000 and $10,000 for the corresponding periods in 2022.

We had 10 manufacturing employees in each of the three months ended of June 30, 2023 and 2022. We expect the number of employees involved in manufacturing will remain consistent in the near future.

Research and development

Research and development expenses are primarily comprised of salaries, benefits, stock-based compensation and other compensation costs associated with research and development personnel, overhead and facility costs, preclinical and non-clinical development costs, clinical trial and related clinical manufacturing costs, contract services, and other outside costs.

Research and development expenses were $7.9 million and $16.5 million for the three and six months ended June 30, 2023 compared to $8.8 million and $17.0 million for the corresponding periods in 2022. We incurred lower research and development costs associated with larsucosterol and the depot injectable programs, partially offset by higher research and development costs associated with other research programs in the three and six months ended June 30, 2023 compared to the corresponding periods in 2022, as more fully discussed below. Stock-based compensation expense recognized related to research and development personnel was $301,000 and $593,000 for the three and six months ended June 30, 2023 compared to $296,000 and $626,000 for the corresponding periods in 2022. As of June 30, 2023, we had 38 research and development employees compared with 43 as of June 30, 2022. We expect research and development expenses in the near future to remain comparable to the second quarter of 2023.


	Three months ended June 30,				Six months ended June 30,
	2023		2022		2023		2022
Larsucosterol	$	7,175	$	8,104	$	14,690	$	15,362
Depot injectable programs		3		376		319		806
Others		768		337		1,530		860
Total research and development expenses	$	7,946	$	8,817	$	16,539	$	17,028

Larsucosterol

Our research and development expenses for larsucosterol were $7.2 million and $14.7 million in the three and six months ended June 30, 2022 compared to $8.1 million and $15.4 million for the corresponding periods in 2022. The decrease in the three months ended June 30, 2023 was primarily due to lower employee-related costs and lower contract research expenses, partially offset by higher clinical trial related expenses and higher contract manufacturing expenses for this drug candidate compared with the corresponding period in 2022. The decrease in the six months ended June 30, 2023 was primarily due to lower contract research expenses, partially offset by higher clinical trial related expenses and higher contract manufacturing expenses for this drug candidate compared with the corresponding period in 2022.

Depot injectable programs

Our research and development expenses for depot injectable programs were $3,000 and $319,000 in the three and six months ended June 30, 2023 compared to $376,000 and $806,000 for the corresponding periods in 2022. The decreases in the three and six months ended June 30, 2023 were primarily due to lower employee-related costs and lower outside expenses for these programs compared with the corresponding periods in 2022.

Other DURECT research programs

Our research and development expenses for all other programs were $768,000 and $1.5 million in the three and six months ended June 30, 2023 compared to $337,000 and $860,000 for the corresponding periods in 2022. The increases in the three and six months ended June 30, 2023 were primarily due to higher employee-related costs and higher outside expenses associated with these programs compared with the corresponding periods in 2022.

Our research and development programs may span as many as ten years or more, and estimation of completion dates or costs to complete are highly speculative and subjective due to numerous risks and uncertainties associated with developing pharmaceutical products, including significant and changing government regulation, uncertainties of future preclinical and clinical study results, uncertainties with our collaborators’ commitment to and progress in the programs and uncertainties associated with process development and manufacturing as well as sales and marketing. In addition, with respect to our development programs subject to third-party collaborations, the timing and expenditures to complete the programs are subject to the control of our collaborators.

Therefore, we cannot reasonably estimate the timing and costs of the efforts necessary to complete the research and development programs. For additional information regarding these risks and uncertainties, see Part I, Item 1A., “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Selling, general and administrative. Selling, general and administrative expenses are primarily comprised of salaries, benefits, stock-based compensation and other compensation costs associated with finance, legal, business development, sales and marketing and other administrative personnel, overhead and facility costs, and other general and administrative costs.

Selling, general and administrative expenses were $3.8 million and $7.9 million in the three and six months ended June 30, 2023 compared to $4.0 million and $7.7 million for the corresponding periods in 2022. The decrease in the three months ended June 30, 2023 was primarily due to lower patent expenses and lower recruiting expenses compared to the corresponding period in 2022. The increase in the six months ended June 30, 2023 was primarily due to higher market research expenses, higher audit related expenses as well as higher employee expenses compared to the corresponding period in 2022. Stock-based compensation expense recognized related to selling, general and administrative personnel was $353,000 and $659,000 for the three and six months ended June 30, 2023 compared to $317,000 and $660,000 for the corresponding periods in 2022.

We had 24 selling, general and administrative employees as of June 30, 2023 compared with 25 as of June 30, 2022. We expect selling, general and administrative expenses in the near future to be comparable to the second quarter of 2023.

Other income (expense). Other expense was $1.1 million and $2.1 million in the three and six months ended June 30, 2023 compared to $465,000 and $941,000 for the corresponding periods in 2022.

Interest income was $511,000 and $1.0 million in the three and six months ended June 30, 2023 compared to $127,000 and $181,000 for the corresponding periods in 2022. The increases in the three and six months ended June 30, 2023 were primarily due to higher interest rates associated with our cash, cash equivalents and investments compared with the corresponding periods in 2022.

Interest expense was $749,000 and $1.5 million in the three and six months ended June 30, 2023 compared to $592,000 and $1.1 million for the corresponding periods in 2022. The increases in the three and six months ended June 30, 2023 were primarily due to higher interest rates on our term loan compared with the corresponding periods in 2022.

Other income (expenses) for the three months ended June 30, 2023 also includes approximately $892,000 non-cash loss associated with the change in fair value of the liability-classified warrants issued in connection with the offering in February 2023. Other income (expenses) for the six months ended June 30, 2023 also includes $1.2 million of issuance costs of these warrants as well as approximately $2.0 million non-cash loss on the issuance of these warrants, which was partially offset by approximately $1.6 million non-cash gain associated with the change in fair value of these liability-classified warrants in the period.

Liquidity and Capital Resources

We had cash, cash equivalents and investments totaling $34.9 million at June 30, 2023 compared to cash, cash equivalents, and investments of $43.6 million at December 31, 2022. These balances include $150,000 of interest-bearing marketable securities classified as restricted investments on our balance sheets as of June 30, 2023 and December 31, 2022. The decrease in cash, cash equivalents and investments was primarily due to cash used in ongoing operating activities, principal and interest payments on the term loan, partially offset by approximately $8.8 million of net proceeds received from the offering in February 2023, net proceeds from the sale of our common stock in the open market and payments received from collaboration partners and customers.

Our cash and investments policy emphasizes liquidity and preservation of principal over other portfolio considerations. We select investments that maximize interest income to the extent possible given these two constraints. We satisfy liquidity requirements by investing excess cash in securities with different maturities to match projected cash needs and limit concentration of credit risk by diversifying our investments among a variety of high credit-quality issuers.

As discussed below, we do not have sufficient cash resources to fund our planned operations, existing debt and contractual commitments and planned capital expenditures. Unless we secure additional equity or debt financing, of which there can be no assurance, we may not be able to continue operations.

Cash Flows

We used $18.6 million of cash in operating activities for the six months ended June 30, 2023 compared to $15.6 million for the corresponding period in 2022. The increase in cash used in operating activities was primarily due to lower payments from our collaborators. The cash used in operations was primarily to fund operations as well as our working capital requirements, partially offset by the changes in accounts receivable, accounts payable and accrued liabilities.

We used $3.1 million of cash in investing activities for the six months ended June 30, 2023 compared to $12.9 million provided by investing activities for the corresponding period in 2022. The decrease in cash provided by investing activities was primarily due to an increase in net purchases of available-for-sale securities partially offset by a decrease in proceeds from maturities of available-sale-securities for the six months ended June 30, 2023 compared with the corresponding period in 2022.

We received $10.0 million of cash from financing activities for the six months ended June 30, 2023 compared to $34,000 for the corresponding period in 2022. The increase in cash received from financing activities was primarily due to cash proceeds received from the offering that was completed in February 2023 and from the sale of our common stock in the open market under the 2021 Sales Agreement in the six months ended June 30, 2023.

We anticipate that cash used in operating activities in the near future will increase compared to the second quarter of 2023 as we experience higher research and development expenses related to larsucosterol and other research programs.

Shelf Registration Statement

In July 2021, we filed a shelf registration statement on Form S-3 with the SEC (the “2021 Registration Statement”) (File No. 333-258333), which upon being declared effective in August 2021, terminated our registration statement filed in August 2018 (File No. 333-226518) and allowed us to offer up to $250.0 million of securities from time to time in one or more public offerings, inclusive of up to $75.0 million of shares of our common stock which we may sell, subject to certain limitations, pursuant to a sales agreement dated July 30, 2021 with Cantor Fitzgerald (the “2021 Sales Agreement”). The 2021 Sales Agreement replaced a prior 2015 Sales Agreement.

As of August 7, 2023, we had up to $224.3 million of our securities available for sale under the 2021 Registration Statement, of which $74.3 million of our common stock are available pursuant to the 2021 Sales Agreement.

Any material sales in the public market of our common stock, under the 2021 Sales Agreement or otherwise under the 2021 Registration Statement, could adversely affect prevailing market prices for our common stock.

Term Loan

In July 2016, we entered into a Loan and Security Agreement (as amended, the "Loan Agreement") with Oxford Finance LLC ("Oxford Finance"), pursuant to which Oxford Finance provided a $20.0 million secured single-draw term loan to us with an initial maturity date of August 1, 2020. The term loan was fully drawn at close and the proceeds may be used for working capital and general business requirements. The term loan repayment schedule provided initially for interest only payments for the first 18 months, followed by consecutive monthly payments of principal and interest in arrears starting on March 1, 2018 and continuing through the maturity date of August 1, 2020. Following five amendments, we make interest only payments under the amended Loan Agreement until June 1, 2023 and the final maturity date of the loan is September 1, 2025. The Loan Agreement provides for a floating interest rate (7.95% initially and 12.55% as of June 30, 2023) based on an index rate plus a spread and an additional payment equal to 10% of the principal amount of the term loan, which is due when the term loan becomes due or upon the prepayment of the facility. If we elect to prepay the loan, there is also a prepayment fee between 0.75% and 2.5% of the principal amount of the term loan depending on the timing of prepayment. Our debt repayment obligations under the Loan Agreement, as amended, may prove a burden to the Company as they become due, particularly following the expiration of the interest-only period.

The term loan is secured by substantially all of our assets, except that the collateral does not include any intellectual property (including licensing, collaboration and similar agreements relating thereto), and certain other excluded assets. The Loan Agreement contains customary representations, warranties and covenants by us, which covenants limit our ability to convey, sell, lease, transfer, assign or otherwise dispose of certain assets; engage in any business other than the businesses currently engaged in by us or reasonably related thereto; liquidate or dissolve; make certain management changes; undergo certain change of control events; create, incur, assume, or be liable with respect to certain indebtedness; grant certain liens; pay dividends and make certain other restricted payments; make certain investments; and make payments on any subordinated debt.

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, our failure to fulfill certain obligations under the Loan Agreement and the occurrence of a material adverse change which is defined as a material adverse change in our business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of any portion of the loan, or a material impairment in the perfection or priority of lender’s lien in the collateral or in the value of such collateral. In the event of default by us under the Loan Agreement, the lender would be entitled to exercise its remedies thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement. As a result, the term loan was classified as a current liability on our balance sheet as of June 30, 2023 and December 31, 2022 due to recurring losses, liquidity concerns and a subjective acceleration clause in the Loan Agreement.

Going Concern

As of June 30, 2023, we had approximately $34.9 million in cash, cash equivalents and investments compared with $43.6 million as of December 31, 2022. In February 2023, we received $10.0 million of gross proceeds from the offering and incurred placement agent fees and other estimated offering expenses of $1.2 million. In the three months ended June 30, 2023, we raised net proceeds (net of commissions) of approximately $658,000 from the sale of our common stock in the open market under the 2021 Sales Agreement. In July 2023, we sold 2,991,027 shares of common stock and accompanying warrants to purchase up to 2,991,027 shares of common stock in a registered direct offering priced at-the-market under Nasdaq rules. The shares of common stock and accompanying warrants were sold at a combined purchase price of $5.015 per share and accompanying warrant. The warrants have an exercise price of $4.89 per share, are immediately exercisable and will expire five years from the date of issuance. The net proceeds

from the offering to the Company were approximately $13.8 million after deducting placement agent fees and other estimated offering expenses.

In accordance with ASU No. 2014-15 Presentation of Financial Statements – Going Concern (subtopic 205-40), our management evaluates whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued. Based on our evaluation, substantial doubt exists regarding our ability to continue as a going concern for a period of one year from the issuance of our financial statements.

Presently, we do not have sufficient cash resources to fund our planned operations, existing debt and contractual commitments and planned capital expenditures through at least the next 12 months from issuance of these financial statements. We may consume available resources more rapidly than currently anticipated, resulting in the need for additional funding. We expect to incur continuing losses and negative cash flows from operations for the foreseeable future.

We may decide to raise additional capital through a variety of sources in the short-term and in the long-term, including but not limited to:

•

the public equity markets;

•

private equity financings;

•

collaborative arrangements;

•

asset sales; and/or

•

public or private debt.

There can be no assurance that we will enter into additional collaborative agreements or maintain existing collaborative agreements, will earn collaborative revenues or that additional capital will be available on favorable terms to the Company, if at all. If adequate funds are not available, we may be required to significantly reduce or re-focus our operations or to obtain funds through arrangements that may require us to relinquish rights to certain of our products, technologies or potential markets, either of which could have a material adverse effect on our business, financial condition and results of operations. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of such securities would result in ownership dilution to our existing stockholders (assuming convertible debt securities were converted into shares). These factors raise substantial doubt regarding our ability to continue as a going concern. Our inability to obtain required funding in the near future or our inability to obtain funding on favorable terms will have a material adverse effect on our operations and strategic development plan for future growth. If we cannot successfully raise additional capital and implement our strategic development plan, our liquidity, financial condition and business prospects will be materially and adversely affected, and we may have to cease operations.

As a result of our recurring losses from operations, negative cash flows from operating activities and need to raise additional capital, our independent registered public accounting firm included an explanatory paragraph in its report on our audited financial statements for the year ended December 31, 2022 related to our going concern evaluation.

During the six months ended June 30, 2023, there were no significant changes in our commercial commitments and contractual obligations as compared with the information presented in our Annual Report on Form 10-K for the year ended December 31, 2022.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As of June 30, 2023, our exposure to market risk has not changed materially since December 31, 2022. For more information on financial market risks related to changes in interest rates, reference is made to Part II, Item 7A., “Quantitative and Qualitative Disclosures About Market Risk” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on March 8, 2023.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures: The Company’s principal executive and principal financial officers reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, the Company’s principal executive and principal financial officers concluded that as of the end of the period covered by this Quarterly Report on Form 10-Q the Company’s disclosure controls and procedures are effective at ensuring that information required to be disclosed by the Company in reports that the Company files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and is accumulated and communicated to management, including the Company’s principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting: There were no significant changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the Company’s most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

We are not a party to any material legal proceedings.

Item 1A. Risk Factors.

You should carefully consider the factors discussed in Part I, Item 1A., “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which could materially affect our business, financial position, or future results of operations. The risks described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial position, or future results of operations. We may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC. The risk factor set forth below supplements and updates the risk factors previously disclosed and should be read together with the risk factors described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and with any risk factors we may include in subsequent periodic filings with the SEC.

Risks Related To Our Business

We contract with third parties for the manufacture of larsucosterol and expect to continue to do so for any required additional clinical trials as well as the commercialization of larsucosterol. Our reliance on third parties increases the risk that submissions for regulatory approval of larsucosterol may be delayed or that we will not have sufficient quantities of larsucosterol available at an acceptable cost, which could delay, prevent or impair our development and commercialization efforts of larsucosterol

We currently rely on third-party contractors to manufacture, package, label and distribute clinical supplies of injectable larsucosterol, and we expect to establish supply agreements for commercial quantities of larsucosterol following approval for marketing by applicable regulatory authorities. We also expect to rely on third-party contractors to manufacture larsucosterol for use in our clinical trials. As of the filing date of this Quarterly Report on Form 10-Q, our third-party manufacturer has not established a final process for the commercial supply of injectable larsucosterol and neither we nor our third-party manufacturer have completed stability testing required to submit and obtain regulatory approval for the use of larsucosterol in the treatment of AH. Reliance on third-party contractors entails risks including, but not limited to:

•

our inability to identify and negotiate manufacturing and supply agreements with suitable manufacturers;

•

delays in the development of manufacturing process technologies and stability testing;

•

our inability to control manufacturing process development and its timing;

•

manufacturing delays if our third-party contractors give greater priority to the supply of other products over larsucosterol or otherwise do not satisfactorily perform according to the terms of our agreements with such contractors;

•

possible terminations or nonrenewals of agreements by our third-party contractors at a time that is costly or inconvenient for us;

•

possible breaches by third-party contractors of our agreements with such contractors;

•

failures by third-party contractors to comply with applicable regulatory requirements;

•

possible mislabeling of clinical supplies, which could result in the supply of incorrect dose amounts or the improper identification of the active drug and/or placebo;

•

the possibility that clinical supplies will not be delivered to clinical sites on time, leading to clinical trial interruptions, or that drug supplies will not be distributed to commercial vendors in a timely manner, resulting in lost sales; or

•

possible misappropriations of our proprietary information, including our trade secrets and know-how.

Additionally, we may incur delays in the regulatory submissions or approval of larsucosterol due to manufacturing process development and stability testing, or from the need to identify or qualify alternative third-party manufacturers. Our current and anticipated future dependence upon third parties for the manufacturing of larsucosterol may adversely affect our future profit margins and our ability to commercialize any of our products that receive marketing approval on a timely and competitive basis.
