Item 7. Management’s Discussion and Analysis
Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following management’s discussion and analysis of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and notes thereto included as part of this Annual Report. This discussion contains forward-looking statements that reflect our plans, estimates and beliefs and involve risks and uncertainties. Our actual results and the timing of certain events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those discussed in the section titled “Risk Factors” included under Part I, Item 1A and elsewhere in this Annual Report. See “Special Note Regarding Forward-Looking Statements” in this Annual Report.
Overview
We are a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of next generation targeted therapies for women’s cancers. We are advancing our pipeline of novel therapies by leveraging our deep understanding of endocrine-driven cancers, nuclear receptors, and mechanisms of acquired resistance. Our lead product candidate, palazestrant (OP-1250), is a novel, orally-available small molecule with dual activity as both a complete estrogen receptor, or ER, antagonist, or CERAN, and selective ER degrader, or SERD, currently being investigated in patients with recurrent, locally advanced or metastatic ER-positive, or ER+, human epidermal growth factor receptor 2-negative, or HER2-, breast cancer. In preclinical models, palazestrant binds and completely blocks ER-driven transcriptional activity in both wild-type and mutant forms of metastatic ER+ breast cancer including activity in central nervous system, or CNS, metastases models. In clinical studies across more than 250 patients, palazestrant has demonstrated strong anti-tumor activity, attractive pharmacokinetics and prolonged drug exposure, favorable tolerability, and combinability with CDK4/6 inhibitors with no significant drug-drug interaction. Palazestrant is currently being evaluated both as a single agent in an ongoing Phase 3 clinical trial, OPERA-01, and in Phase 2 combination studies with a CDK4/6 inhibitor (palbociclib or ribociclib) and a phosphatidylinositol 3 kinase alpha, or PI3Ka, inhibitor (alpelisib).
We reported positive Phase 2 clinical results for palazestrant as a monotherapy in October 2023 at the European Society for Medical Oncology, or ESMO, Congress 2023, which demonstrated compelling progression-free survival, or PFS, a favorable tolerability profile and attractive pharmacokinetics in a heavily pretreated patient population. These results validated the potential opportunity for palazestrant as a monotherapy agent in later lines of treatment for metastatic breast cancer, and in November 2023 we initiated OPERA-01, our pivotal Phase 3 second-, third-line monotherapy clinical trial. We anticipate the top-line results from the OPERA-01 trial in 2026.
We are investigating palazestrant in combination with CDK4/6 inhibitors, palbociclib and ribociclib, and a PI3Ka inhibitor, alpelisib. We reported interim results of our ongoing Phase 2 dose expansion clinical studies of palazestrant in combination with each of palbociclib and ribociclib at the 2023 San Antonio Breast Cancer Symposium in December 2023. Across both studies, the interim results demonstrated no significant drug-drug interaction, no dose-limiting toxicities and a tolerability profile consistent with the FDA-approved labels of ribociclib or palbociclib plus an endocrine therapy. Both studies are being conducted at palazestrant recommended Phase 2 dose, or RP2D, of 120 mg combined with the full FDA-approved label doses of palbociclib 125 mg, or ribociclib 600 mg. In October 2023, we announced the expansion of our clinical collaboration with Novartis Institutes for BioMedical Research, Inc., or Novartis, increasing the size of the ongoing Phase 1/2 clinical study testing palazestrant in combination with ribociclib to approximately 60 patients. We will be presenting results from the Phase 2 portion of the palazestrant-ribociclib combination clinical study at the ESMO Breast Cancer Annual Congress 2024 in May 2024 in Berlin. Furthermore, we expect the data from the Phase 2 palazestrant-ribociclib combination clinical study will enable us to prepare to initiate a pivotal Phase 3 first-line clinical trial of palazestrant in combination with ribociclib. We also plan to initiate evaluation of palazestrant in combination with an mTOR inhibitor, everolimus, in a Phase 1b/2 clinical study, anticipated in the third quarter of 2024.

In July 2022, we were granted Fast Track designation from the U.S. Food and Drug Administration, or the FDA, for palazestrant for patients with ER+/HER2- metastatic breast cancer that has progressed following one or more lines of endocrine therapy with at least one line given in combination with a CDK4/6 inhibitor.
In addition, in October 2023 we presented new preclinical data regarding the discovery of novel compounds targeting KAT6, an epigenetic target that is dysregulated in breast and other cancers. In January 2024, we nominated a development candidate for this program, OP-3136, and we expect to file an Investigational New Drug, or IND, application with the FDA in late 2024 and advance into clinical development. In a non-clinical xenograft model, OP-3136 caused dose-dependent tumor growth inhibition and tumor regression comparable to or better than a positive-control patented KAT6 inhibitor and demonstrated synergy in combination with CDK4/6 inhibitors or palazestrant. We are advancing the development of this program in collaboration with Aurigene Oncology, or Aurigene.
Since our inception, we have devoted substantially all of our resources to organizing and staffing our company, research and development activities, business planning, raising capital, establishing and maintaining our intellectual property portfolio, conducting nonclinical studies and clinical trials and providing general and administrative support for these operations.
We do not have any product candidates approved for commercial sale, and we have not generated any revenue from product sales. Our ability to generate product revenue sufficient to achieve profitability, if ever, will depend on the successful development and eventual commercialization of one or more of our product candidates which we expect, if it ever occurs, will take a number of years. We also do not own or operate, and currently have no plans to establish, any manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for nonclinical and clinical testing, as well as for commercial manufacturing if any of our product candidates obtain marketing approval. We believe that this strategy allows us to maintain a more efficient infrastructure by eliminating the need for us to invest in our own manufacturing facilities, equipment and personnel while also enabling us to focus our expertise and resources on the development of our product candidates.
We have incurred significant operating losses since the commencement of our operations. Our net losses were $96.7 million and $104.8 million for the years ended December 31, 2023 and 2022, respectively. We expect to incur significant and increasing losses for thea foreseeable future as we continue to advance our product candidates, make potential milestone payments to our licensors, and as we continue to operate as a public company. Our net losses may fluctuate significantly from period to period, depending on the timing of expenditures on our research and development activities. As of December 31, 2023, we had an accumulated deficit of $305.6 million. Our primary use of cash is to fund operating expenses, which consist primarily of research and development expenditures and general and administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable and other current liabilities.
We expect to continue to incur net operating losses for at least the next several years, and we expect our research and development expenses, general and administrative expenses, and capital expenditures will continue to increase. We expect our expenses and capital requirements will increase significantly in connection with our ongoing activities as we:
• continue our ongoing and planned research and development of our lead product candidate, palazestrant, for the treatment of ER+ positive breast cancer;
• initiate nonclinical studies and clinical trials for OP-3136 and any additional product candidates that we may pursue in the future;
• seek to discover and develop additional product candidates and further expand our clinical product pipeline;
• seek regulatory approvals for any product candidates that successfully complete clinical trials;
112
Table of Contents
• continue to scale up external manufacturing capacity with the aim of securing sufficient quantities to meet our capacity requirements for clinical trials and potential commercialization;
• establish a sales, marketing and distribution infrastructure to commercialize any approved product candidates and related additional commercial manufacturing costs;
• develop, maintain, expand, protect and enforce our intellectual property portfolio, including patents, trade secrets and know how;
• acquire or in-license other product candidates and technologies;
• attract, hire and retain additional clinical, scientific, quality control, and manufacturing management and administrative personnel;
• add clinical, operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts;
• expand our operations in the United States and to other geographies; and
• incur additional legal, accounting, investor relations and other expenses associated with operating as a public company.
Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials, potential milestone payments to our licensors, and our expenditures on other research and development activities.
We will require substantial additional funding to develop our product candidates and support our continuing operations beyond our current operating plans. Until such time that we can generate significant revenue from product sales or other sources, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, which could include income from collaborations, strategic partnerships or marketing, distribution, licensing or other strategic arrangements with third parties, or from grants. We may be unable to raise additional funds or to enter into such agreements or arrangements on favorable terms, or at all. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions or volatility in the credit and financial markets in the United States and worldwide resulting from geopolitical and macroeconomic conditions. Our failure to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on our business, results of operations or financial condition, including requiring us to have to delay, reduce or eliminate our product development or future commercialization efforts. Insufficient liquidity may also require us to relinquish rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our development efforts. We cannot provide assurance that we will ever be profitable or generate positive cash flow from operating activities.
Global economic and business activities continue to face widespread geopolitical and macroeconomic uncertainties, including labor shortages, inflation rates and the responses by central banking authorities to control such inflation, monetary supply shifts, and related financial market risks and instability, recession risks, as well as potential disruptions from the Russia-Ukraine conflict and armed conflict between Israel and groups based in surrounding regions, all of which have resulted in volatility in the U.S. and global financial markets, and disruptions to trade, commerce, pricing stability, credit availability and supply chain continuity globally. The extent of the impact of these factors on our operational and financial performance, including our ability to execute our business strategies and initiatives in the expected time frame, will depend on future developments, which are uncertain and cannot be predicted. Any continued or renewed disruption resulting from these factors could negatively impact our business. We continue to monitor the impact of these geopolitical and macroeconomic factors on our results of operations, financial condition and cash flows.

Components of our results of operations
Revenue
To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products for the foreseeable future.
Operating expenses
Research and development
Research and development expenses account for a significant portion of our operating expenses and consist primarily of external and internal expenses incurred in connection with the discovery and development of our product candidates. To date, our research and development expenses have related primarily to discovery efforts and nonclinical and clinical development of our lead product candidate, palazestrant, as well as OP-3136. Research and development expenses are recognized as incurred and 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.
External expenses include:
• expenses incurred in connection with the discovery and nonclinical development of our product candidates, including under agreements with third parties, such as consultants and contract research organizations, or CROs;
• costs of manufacturing products for use in our nonclinical studies and clinical trials, including payments to contract manufacturing organizations, or CMOs, and consultants;
• costs of funding research performed by third parties;
• costs of purchasing lab supplies and non-capital equipment used in designing, developing and manufacturing nonclinical study and clinical trial materials;
• costs associated with consultants for chemistry, manufacturing and controls development, regulatory, statistics and other services;
• expenses related to regulatory activities, including filing fees paid to regulatory agencies; and
• facility costs including rent, depreciation and maintenance expenses.
Internal expenses include employee and personnel-related costs and expenses, including salaries, benefits and stock-based compensation expense for employees and personnel engaged in research and development functions.
We expense research and development expenses in the periods in which they are incurred. Costs for certain activities, such as manufacturing and nonclinical studies and clinical trials, are generally recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors and collaborators.
We typically use our employee, consultant and infrastructure resources across our development programs. We track outsourced development costs by product candidate or nonclinical program, but we do not allocate personnel costs, other internal costs or external consultant costs to specific product candidates or nonclinical programs.
114
Table of Contents
While our research and development expenses may fluctuate from period to period, we generally expect our research and development expenses to increase substantially in absolute dollars for the foreseeable future as we advance palazestrant, OP-3136 or any other future product candidates we may develop into and through nonclinical studies and clinical trials and pursue regulatory approval of our product candidates. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for palazestrant, OP-3136 or any other future product candidates we may develop may be affected by a variety of factors including but not limited to: the safety and efficacy of our product candidates, early clinical data, investment in our clinical program, the ability of collaborators to successfully develop our licensed product candidates, competition, manufacturing capability and commercial viability. We may never succeed in achieving regulatory approval for our product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of palazestrant, OP-3136 or any other future product candidates we may develop. Clinical and nonclinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the results of ongoing and future nonclinical studies and clinical trials, regulatory developments and our ongoing assessments as to each product candidate’s commercial potential. In addition, we cannot forecast whether palazestrant, OP-3136 or any other future product candidates we may develop may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements. We are also unable to predict when, if ever, we will generate revenue from our product candidates to offset these expenses. Our expenditures on current and future nonclinical and clinical development programs are subject to numerous uncertainties in timing and cost to completion. The duration, costs and timing of nonclinical studies and clinical trials and development of our product candidates will depend on a variety of factors, including:
• the timing and progress of nonclinical and clinical development activities;
• the number and scope of nonclinical and clinical programs we decide to pursue;
• our ability to maintain our current research and development programs and to establish new ones;
• establishing an appropriate safety profile with investigational new drug-enabling toxicology studies;
• successful patient enrollment in, and the initiation and completion of, clinical trials;
• the successful completion of clinical trials with safety, tolerability and efficacy profiles that are satisfactory to the FDA or any comparable foreign regulatory authority;
• establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;
• receipt of regulatory approvals from applicable regulatory authorities;
• the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;
• our ability to establish licensing or collaboration arrangements;
• the performance of our future collaborators, if any;
• development and timely delivery of commercial-grade product formulations that can be used in our planned clinical trials and for commercial launch;
• commercializing the product candidate, if approved, whether alone or in collaboration with others;
115
Table of Contents
• obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;
• obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights;
• maintaining continued acceptable safety profiles of our products following approval; and
• obtaining and retaining key research and development personnel.
Any changes in the outcome of any of these factors could significantly impact the costs, timing and viability associated with the development of our product candidates.
General and administrative
General and administrative expenses consist primarily of personnel expenses, including salaries, benefits and stock-based compensation expense, for personnel in executive, finance, accounting, business development, legal, human resources, information technology, or IT, and administrative functions. General and administrative expenses also include costs not otherwise included in research and development expenses, including corporate facility costs, depreciation and other expenses, which include direct or allocated expenses for rent and maintenance of facilities and insurance, and professional fees for legal, patent and consulting services.
While our general and administrative expenses may fluctuate from period to period, we generally expect that our general and administrative expenses will increase in the foreseeable future as we increase our headcount to support the continued research and development of our programs and the growth of our business. We also anticipate incurring additional expenses associated with operating as a public company, including increased expenses related to the building and improving of our IT infrastructure, including cyber security monitoring, legal, other regulatory and compliance, director and officer insurance, investor and public relations and tax-related services associated with maintaining compliance with the rules and regulations of the SEC and standards applicable to companies listed on a national securities exchange, additional insurance expenses, investor relations activities and other administrative and professional services.
Total other income
Total other income consists of interest income and other expense. Interest income primarily consists of interest income on our cash equivalents and marketable securities. Other expense primarily consists of unrealized foreign currency remeasurement gain (loss), loss on disposal of equipment and miscellaneous income (expense) not related to operating activities.

Research and development expenses for the year ended December 31, 2023 were $86.1 million, compared to $82.3 million for the year ended December 31, 2022. The increase of $3.9 million was primarily due to increased spending on clinical operations and development-related activities, including personnel-related expenses, as we continued to advance palazestrant into late-stage clinical trials. The increase was partially offset by decreased spending on (i) preclinical research programs, including the $8.0 million upfront payment in connection with the exclusive global license agreement entered into in June 2022 between the Company and Aurigene, or the Aurigene Agreement, incurred and paid in June 2022, and (ii) a decrease of approximately $0.7 million in non-cash stock-based compensation expense.
General and administrative expenses
General and administrative expenses for the year ended December 31, 2023 were $18.8 million, compared to $24.7 million for the year ended December 31, 2022. The decrease of $5.9 million was primarily due to decreased spending on (i) corporate and legal-related costs, and (ii) personnel-related expenses, which primarily related to a reduction in headcount as a result of our restructuring and portfolio prioritization, and a decrease of approximately $0.9 million in non-cash stock-based compensation expense.
117
Table of Contents
Other income
Other income for the year ended December 31, 2023 was $8.3 million, compared to $2.2 million for the year ended December 31, 2022. The increase of $6.1 million was primarily due to an increase in interest income from our marketable securities.
Liquidity and capital resources
Sources of liquidity
Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses and negative cash flows from our operations. Our net losses were $96.7 million and $104.8 million for the years ended December 31, 2023 and 2022, respectively. Through December 31, 2023, we had received aggregate gross proceeds of $526.8 million from sales of our common stock, convertible preferred stock and issuance of convertible promissory notes, stock option exercises, and sale of stock through our 2020 Employee Stock Purchase Plan, or ESPP.
As of December 31, 2023, we had $261.8 million in cash, cash equivalents and marketable securities and accumulated deficit of $305.6 million. We had no debt outstanding as of December 31, 2023.
In September 2023, we entered into a stock purchase agreement for a private placement of 13,211,381 shares of our common stock, at a price of $9.84 per share, to selected institutional and accredited investors, or the Private Placement. The Private Placement resulted in gross proceeds of approximately $130.0 million. After deducting offering expenses related to the Private Placement of approximately $0.3 million, the net proceeds to us from the Private Placement were approximately $129.7 million.
Also on September 5, 2023, we entered into a loan and security agreement, or the Loan Agreement, with Silicon Valley Bank, a division of First-Citizens Bank & Trust Company, or the Bank, providing us with an aggregate principal amount of up to $50.0 million, or the Credit Facility, of which $25.0 million became available upon the closing of the Private Placement, and the remaining $25.0 million may be made available upon approval of the Bank in its discretion. The Credit Facility will mature on August 1, 2027. As of December 31, 2023, we had not drawn down from the Credit Facility, and had no other debt outstanding.
On January 5, 2024, we entered into the Sales Agreement with TD Cowen as sales agent, pursuant to which we may offer and sell, from time to time, shares of our common stock, having an aggregate offering price of up to $150.0 million, or the ATM Shares. The sales, if any, of the ATM Shares will be made by any method permitted that is deemed to be an “at-the-market”, or ATM, equity offering as defined in Rule 415(a)(4) promulgated under the Securities Act, including sales made directly on or through the Nasdaq Global Select Market. We have agreed to pay TD Cowen a commission of up to 3.0% of the aggregate gross proceeds from any ATM Shares sold by TD Cowen.
We expect to incur significant expenses and operating losses for the foreseeable future as we advance the clinical development of palazestrant, OP-3136 and nonclinical studies. We expect that our research and development and general and administrative costs will increase in connection with conducting additional nonclinical studies and clinical trials for our current and future research programs and product candidates, contracting with CMOs to support nonclinical studies and clinical trials, expanding our intellectual property portfolio, and providing general and administrative support for our operations. As a result, we will need additional capital to fund our operations, which we may obtain from additional equity or debt financings, collaborations, licensing arrangements or other sources.
Our primary uses of cash are to fund our research and development activities, including with respect to palazestrant, OP-3136 and other nonclinical programs, business planning, establishing and maintaining our intellectual property portfolio, hiring personnel, raising capital and providing general and administrative support for these operations.
118
Table of Contents
Other than as noted above, we currently have no financing commitments, such as lines of credit or guarantees, that are expected to affect our liquidity over the next five years.
Future funding and material cash requirements
To date, we have not generated any revenue from product sales. We do not expect to generate any meaningful revenue unless and until we obtain regulatory approval of and commercialize any of our product candidates, and we do not know when, or if at all, that will occur. We expect our expenses to increase in connection with our ongoing activities, particularly as we initiate and conduct clinical trials of, and seek marketing approval for, palazestrant or OP-3136. In addition, if we obtain marketing approval for our product candidates, we expect to incur significant commercialization expenses related to program sales, marketing, manufacturing and distribution to the extent that such sales, marketing and distribution are not the responsibility of potential collaborators. Furthermore, we have incurred and expect to continue to incur additional costs associated with operating as a public company. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our development efforts.
We expect our cash, cash equivalents, and marketable securities as of December 31, 2023, as well as the available balance under the Credit Facility, will enable us to fund our current operating plan for at least the next 12 months from the filing date of these consolidated financial statements.

(1) We conduct our research and development programs internally and through third parties that include, among others, arrangements with vendors, consultants, CMOs, and CROs. We have contractual arrangements in the normal course of business with these parties, however, our contracts with them are cancelable generally on reasonable notice within one year and our obligations under these contracts are primarily based on services performed. We included certain contracts that have significant cancellation penalties and are material, which make the continuation of these arrangements reasonable.
In addition, under the Aurigene Agreement, we have payment obligations that are contingent upon future events such as the achievement of specified development, regulatory and commercial milestones. Financial terms of the Aurigene Agreement include potential future milestone payments of up to $60.0 million in clinical development and regulatory milestones, and up to $370.0 million in commercial milestones. Aurigene is also eligible to receive mid-single digit to the low double digit royalties as percentages of product sales, if any. The amount and timing of milestone obligations are unknown or uncertain as we are unable to estimate the timing or likelihood of achieving the milestone events. Additionally, the amount of royalty payments are based upon future product sales, which we are unable to predict with certainty. These potential obligations are further described in Note 12 to our audited consolidated financial statements.
We also enter into contracts in the normal course of business with CROs and clinical sites for the conduct of clinical trials, non-clinical research studies, professional consultants for expert advice and other vendors for clinical supply manufacturing or other services. These contracts generally provide for termination on notice, and therefore are cancelable contracts.
If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts. Our future capital requirements will depend on many factors, including:
• the scope, progress, results and costs of product discovery, nonclinical studies and clinical trials;
• the scope, prioritization and number of our research and development programs;
119
Table of Contents
• the costs, timing and outcome of regulatory review of our product candidates;
• our ability to establish and maintain collaborations on favorable terms, if at all;
• the achievement of milestones or occurrence of other developments that trigger payments under any collaboration agreements we enter into;
• the extent to which we are obligated to reimburse, or entitled to reimbursement of, clinical trial costs under collaboration agreements, if any;
• the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
• the extent to which we acquire or in-license other product candidates and technologies;
• the costs of securing manufacturing arrangements for commercial production; and
• the costs of establishing or contracting for sales and marketing capabilities if we obtain regulatory approvals to market our product candidates.
Identifying potential product candidates and conducting nonclinical studies and clinical trials is a time- consuming, expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of a product candidate that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all.
Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, existing stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of existing 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 funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise 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 product candidates that we would otherwise prefer to develop and market ourselves.

Operating activities
Net cash used in operating activities during the year ended December 31, 2023 consisted primarily of our net loss of $96.7 million, partially offset by net non-cash charges of $12.3 million and a net increase of $0.6 million in operating assets and liabilities. The net loss consisted primarily of $86.1 million in research and development expenses and $18.8 million in general and administrative expenses. The non-cash charges consisted primarily of stock-based compensation of $17.3 million, depreciation and amortization expenses of $0.4 million, loss on sale of equipment of $0.1 million, and non-cash lease expense of less than $0.1 million, net of cash payments of $1.2 million. These non-cash expenses were partially offset by net discount accretion on our marketable securities of $5.5 million. The change in operating assets and liabilities was primarily due to (i) an increase of $2.9 million in other current liabilities, and (ii) an increase of $2.3 million in accounts payable, which is primarily resulted from timing of invoicing by vendors and related payments, and (iii) a decrease of $0.7 million in prepaid expenses and other current assets. The changes are mainly offset by an increase of $5.3 million in other assets and long-term deposits.
Net cash used in operating activities during the year ended December 31, 2022 consisted primarily of our net loss of $104.8 million, partially offset by non-cash charges of $18.4 million and a net increase of $4.3 million in net operating assets and liabilities. The net loss consisted primarily of $82.3 million in research and development expenses and $24.7 million in general and administrative expenses. The non-cash charges consisted primarily of stock-based compensation of $18.8 million, depreciation and amortization expenses of $0.4 million, and non-cash lease expense of less than $0.1 million, net of cash payments of $1.3 million. These non-cash expenses were partially offset by net discount accretion on our marketable securities of $0.8 million. The change in operating assets and liabilities was primarily due to (i) an increase of $7.0 million in other current liabilities, and (ii) an increase of $0.4 million in accounts payable, which is primarily resulted from timing of invoicing by vendors and related payments. The changes are partially offset by (i) an increase of $2.0 million in prepaid expenses and other current assets, and (ii) an increase of $1.1 million in other assets mostly due to vendor deposits paid for clinical studies.

Critical accounting estimates
Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The preparation of our consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, expenses and the disclosure of our contingent liabilities in our consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are

reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements elsewhere in this Annual Report, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our audited consolidated financial statements.
Accrued research and development expenses
As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing purchase orders and open contracts, communicating with our personnel and service providers to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the services when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued research and development expenses include the costs incurred for services performed by CROs and CMOs among others, in connection with research and development activities for which we have not yet been invoiced.
We contract with CROs and CMOs to conduct clinical and manufacturing and other research and development services on our behalf. We base our expenses related to CROs and CMOs on our estimates of the services received and efforts expended pursuant to quotes and contracts with them. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our CROs or CMOs will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid expense accordingly. Non-refundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made.
Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. To date, there have been no material differences between our estimates of such expenses and the amounts actually incurred.
Smaller reporting company
Because our annual revenue was less than $100.0 million in 2023 and the market value of our voting and non-voting common stock held by non-affiliates was less than $700.0 million measured on the last business day of our second fiscal quarter in 2023, we qualify as a “smaller reporting company” as defined in the Exchange Act. We took advantage of certain of the scaled disclosures available to smaller reporting companies including, among other things, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act (“Section 404”), presenting only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and presenting reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements.
