Overview

We are a precision oncology company pioneering the discovery and development of small molecule, tumor-agnostic therapies targeting p53. p53 is a well-defined tumor suppressor protein known as the "guardian of the genome," and normal, or wild-type, p53 has the ability to eliminate cancer cells. However, mutant p53 proteins can be misfolded and lose their wild-type tumor suppressing function. These p53 mutations are found in approximately half of all cancers. The field of p53 biology was established by our co-founder Dr. Arnold Levine when he discovered the p53 protein in 1979. We have leveraged more than four decades of research experience and developed unique insights into p53 to create a precision oncology platform designed to generate selective, small molecule, tumor-agnostic therapies that structurally correct specific mutant p53 proteins to restore their wild-type function. We are deploying our precision oncology platform to target p53 mutations and other p53-related cancers.

Since our formation in March 2013, we have devoted substantially all of our time and efforts to performing research and development activities and raising capital. We are not profitable and have incurred losses in each year since our inception. During the three months ended March 31, 2026, we incurred net losses of $18.0 million. As of March 31, 2026, we had an accumulated deficit of $464.5 million. We do not currently have any product candidates approved for sale, and we continue to incur significant research and development and general and administrative expenses related to our operations. We initiated a Phase 1/2 clinical trial, PYNNACLE, in October 2020 for our lead product candidate, rezatapopt. Our strategy is to seek approval under an accelerated pathway, and we believe the Phase 2 portion of the PYNNACLE clinical trial has the potential to serve as a pivotal study. In October 2020, we were granted FDA Fast Track designation of rezatapopt for the treatment of patients with locally advanced or metastatic solid tumors that have a p53 Y220C mutation. In July 2023, we met with the FDA at an End of Phase 1 meeting where alignment was obtained on the recommended Phase 2 dose and key elements of the single arm, Phase 2 registrational portion of the PYNNACLE study. In October 2023, we presented our updated Phase 1 clinical data for rezatapopt at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics Annual Meeting. We dosed our first patient in the pivotal Phase 2 monotherapy portion of the PYNNACLE study in the first quarter of 2024. In September 2025, we announced interim data from the Phase 2 pivotal portion of the PYNNACLE clinical trial, which was updated in October 2025 in a late-breaking oral presentation and poster presentation at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics Meeting. In March 2026, rezatapopt was granted Orphan Drug Designation, or ODD, from the FDA for the treatment of TP53 Y220C positive ovarian cancer, fallopian tube cancer, and primary peritoneal cancer. We plan to submit a New Drug Application, or NDA, for the treatment of patients with platinum-resistant/refractory ovarian cancer harboring a TP53 Y220C mutation to the FDA for rezatapopt in the first quarter of 2027.

We expect that our operating expenses will increase significantly as we advance our product candidates through preclinical and clinical development, seek regulatory approval, and prepare for and, if approved, proceed to commercialization; acquire, discover, validate, and develop additional product candidates; obtain, maintain, protect, and enforce our intellectual property portfolio; and hire additional personnel. We expect to continue to incur significant losses for the foreseeable future.

Our ability to generate product revenue will depend on the successful development, regulatory approval, and eventual commercialization of one or more of our product candidates. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through private or public equity or debt financings, collaborative, or other arrangements with corporate sources, or through other sources of financing. Adequate funding may not be available to us on acceptable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the development and commercialization of our product candidates.

We plan to continue to use third-party service providers, including clinical research organizations, or CROs, and contract manufacturing organizations, or CMOs, to carry out our preclinical and clinical development and to manufacture and supply the materials to be used during the development and commercialization of our product candidates. We do not currently have a sales force.

Components of Results of Operations

Revenue

To date, we have not generated any revenue from any sources, including from product sales, and we do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts for our product candidates are successful and result in regulatory approval, or result in license agreements with third parties, we may generate revenue in the future from product sales or license agreements. However, there can be no assurance as to when we will generate such revenue, if at all.

Operating Expenses

Research and Development Expenses

Our research and development expenses consist primarily of costs incurred to conduct research, such as the discovery and development of our product candidates as well as the development of future product candidates. Research and development expenses include personnel costs, including stock-based compensation expense, third-party contractor services, laboratory materials and supplies, and depreciation and maintenance of research equipment. We expense research and development costs as they are incurred.

We do not allocate our costs by product candidate or development program, as a significant amount of research and development expenses include compensation costs, materials, supplies, depreciation on and maintenance of research equipment, and the cost of services provided by outside contractors, which are not tracked by product candidate or development program. In particular, with respect to internal costs, several of our departments support multiple product candidate research and development programs, and therefore the costs cannot be allocated to a particular product candidate or development program. Substantially all of our research and development costs are associated with our lead product candidate, rezatapopt. We initiated our Phase 1/2 PYNNACLE clinical trial in October 2020, and on that date, we were granted FDA Fast Track designation of rezatapopt for the treatment of patients with locally advanced or metastatic solid tumors that have a p53 Y220C mutation. In October 2023, we presented our updated Phase 1 clinical data for rezatapopt at the 2023 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics Meeting. In September 2025, we announced interim data from the Phase 2 pivotal portion of the PYNNACLE clinical trial, which was updated in October 2025 in a late-breaking oral presentation and poster presentation at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics Meeting. In March 2026, rezatapopt was granted ODD from the FDA for the treatment of TP53 Y220C positive ovarian cancer, fallopian tube cancer, and primary peritoneal cancer. We plan to submit an NDA for the treatment of patients with platinum-resistant/refractory ovarian cancer harboring a TP53 Y220C mutation to the FDA for rezatapopt in the first quarter of 2027.

We expect to continue to incur substantial research and development expenses in the future as we advance our product candidates into and through 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 our product candidates may be affected by a variety of factors including: the safety and efficacy of our product candidates, clinical data, investment in our clinical program, the ability of any future collaborators to successfully develop our licensed product candidates, competition, manufacturing capability, and commercial viability. We may never succeed in achieving regulatory approval for any of 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.

General and Administrative Expenses

General and administrative expenses include personnel costs, expenses for outside professional services and other allocated expenses. Personnel costs consist of salaries, bonuses, benefits, and stock-based compensation. Outside professional services consist of legal, accounting and audit services and other consulting fees. Allocated expenses consist of rent expense related to our office and research and development facilities. We have incurred expenses related to compliance with the rules and regulations of the SEC, and those of any national securities exchange on which our securities are traded, additional insurance expenses, investor relations activities and other administrative and professional services. We also expect to increase our general and administrative expenses as we advance our product candidates through preclinical research and development, manufacturing, clinical development, and commercialization.

Interest Income, Net

Interest income, net, primarily consists of interest income from our interest-bearing cash, cash equivalents, and marketable securities, and interest costs related to accretion and amortization of discounts and premiums on marketable securities.

Results of Operations

Comparison of the Three Months Ended March 31, 2026 and 2025

The following table summarizes our results of operations (in thousands):

Research and Development Expenses

The following table summarizes our research and development expenses incurred during the periods indicated (in thousands):

Research and development expenses were $15.3 million for the three months ended March 31, 2026, compared to $17.4 million for the three months ended March 31, 2025. The decrease of $2.1 million, compared to the three months ended March 31, 2025, was primarily due to the following:

General and Administrative Expenses

General and administrative expenses were $3.7 million for the three months ended March 31, 2026, compared to $4.1 million for the three months ended March 31, 2025. The decrease of $0.4 million, compared to the three months ended March 31, 2025, was primarily due to a $0.1 million decrease in personnel expenses and a $0.3 million decrease in finance and legal support costs.

Interest Income, Net

Interest income, net primarily consists of interest income from our interest-bearing cash, cash equivalents, and marketable securities and interest costs related to accretion and amortization of discounts and premiums on marketable securities. Interest income, net was $1.0 million for the three months ended March 31, 2026, compared to $1.9 million for the three months ended March 31, 2025. The decrease of $0.9 million compared to the three months ended March 31, 2025 was driven by a decline in interest rates combined with lower overall balances in interest-bearing cash, cash equivalents, and investments in marketable securities during the three months ended March 31, 2026.

Income Tax Benefit

The State of New Jersey's Technology Business Tax Certificate Program allows certain high technology and biotechnology companies to sell NOL carryforwards and R&D tax credits to other New Jersey-based corporate taxpayers. As of March 31, 2025, we received $18.4 million of cash for the NOL and R&D tax credit sales related to the tax years ended December 31, 2015 to 2023. The sale of the NOLs and R&D tax credits have been recorded as an income tax benefit within the condensed consolidated statement of operations. For the three months ended March 31, 2025, we had reached the sale limit established by the program and received a benefit for income taxes of $2.2 million. We did not receive any benefit for income taxes for the three months ended March 31, 2026.

Liquidity and Capital Resources

Our financial condition is summarized as follows (in thousands):

Sources of Liquidity

Since our inception, we have not generated any revenue from any product sales or any other sources and have incurred significant operating losses and negative cash flows from our operations. We have not yet commercialized any of our product candidates. Even if the Company's drug development and commercialization efforts are successful, it is uncertain when, if ever, the Company will realize revenue from product sales. As of March 31, 2026, we had cash, cash equivalents, and marketable securities of $93.5 million and an accumulated deficit of $464.5 million. We have financed our operations primarily through issuance and sales of our equity securities.

On November 20, 2024 we filed a shelf registration statement on Form S-3 (File No. 333-283349) with the SEC and a prospectus supplement, which registered the offering, issuance and sale of up to $200.0 million of various equity and debt securities and up to $113.8 million of common stock pursuant to an at-the-market equity offering program with Jefferies LLC, dated October 4, 2021, or the ATM Program. The SEC declared the registration statement effective on November 27, 2024. During the three months ending March 31, 2026, we did not sell any shares of our common stock pursuant to the ATM Program. As of March 31, 2026, we had approximately $113.8 million remaining in gross proceeds available for future issuances of common stock under the ATM Program.

Contractual Obligations and Commitments

We enter into contracts in the normal course of business with CROs and other vendors to assist in the performance of our research and development activities and other services and products for operating purposes. These contracts generally provide for termination on notice, and therefore are cancelable contracts.

In September 2024, we signed two subleases, one for 14,201 square feet of office space at 400 Alexander Park Drive, Suite 301, in Princeton, New Jersey, to be used as our new headquarters, or the 400 Alexander Sublease, and the other for 3,205 square feet of office and laboratory space at 311 Pennington Rocky Hill in Hopewell, New Jersey, to be used for our new laboratory space, or the 311 Pennington Sublease. The 400 Alexander Sublease term extends until February 2027. Amounts related to future lease payments for the 400 Alexander Sublease as of March 31, 2026, totaled $0.3 million with $0.3 million to be paid within the next 12 months. In March 2026, the 311 Pennington Sublease was terminated by the sublessor and we recorded a net gain of approximately $24, which was recognized in General and Administrative expense.

Plan of Operation and Future Funding Requirements

We use our capital resources primarily to fund operating expenses, mainly research and development expenditures. At this time, due to the inherently unpredictable nature of preclinical and clinical development, we cannot reasonably estimate the costs we will incur and the timelines that will be required to complete development, obtain marketing approval and commercialize our current product candidates or any future product candidates, if at all. For the same reasons, we are also unable to predict when, if ever, we will generate revenue from product sales or whether, or when, if ever, we may achieve profitability. Clinical and preclinical development timelines, the probability of success, and development costs can differ materially from expectations. In addition, we cannot forecast which product candidates 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.

Due to our significant research and development expenditures, we have generated substantial operating losses in each period since inception. We have incurred an accumulated deficit of $464.5 million through March 31, 2026. We expect to incur substantial additional losses in the future. For the three months ended March 31, 2026 and 2025, our cash operating expenditures were $19.7 million and $18.3 million, respectively. Based on our research and development plans, we expect that our cash, cash equivalents, and marketable securities as of March 31, 2026 will be sufficient to fund our planned operations until the end of the second quarter of 2027.

We have based this estimate on assumptions that may prove to be wrong, however, and we could use our capital resources sooner than we expect.

The timing and amount of our operating expenditures will depend largely on:

Until such time, if ever, as we can generate substantial revenue from product sales, we expect to fund our operations and capital funding needs through equity and/or debt financing. We may also consider entering into collaboration arrangements or selectively partnering for clinical development and commercialization. The sale of additional equity would result in additional dilution to our stockholders. The incurrence of debt financing would result in debt service obligations and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations or our ability to incur additional indebtedness or pay dividends, among other items. If we raise additional funds through governmental funding, collaborations, strategic partnerships and alliances or marketing, distribution, 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 grant licenses on terms that may not be favorable to us. If we are not able to secure adequate additional funding, we may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. Any of these actions could materially and adversely affect our business, financial condition, results of operations and prospects.

Cash Flows

The following table summarizes our cash flows for the period indicated (in thousands):

Operating Activities

Net cash used in operating activities for the three months ended March 31, 2026, was $19.7 million, which consisted primarily of net loss of $18.0 million, partially offset by non-cash charges of $1.0 million. Changes in our net operating assets decreased operating cash by $2.7 million. The non-cash charges primarily consisted of stock-based compensation of $1.4

million, and accretion of discounts on marketable securities of $0.4 million. The change in our net operating assets and liabilities was primarily due to a decrease in outstanding payables and accrued expenses.

Net cash used in operating activities for the three months ended March 31, 2025, was $18.3 million, which consisted primarily of net loss of $17.4 million partially offset by non-cash charges of $0.7 million. Changes in our net operating assets decreased operating cash by $1.5 million. The non-cash charges primarily consisted of stock-based compensation of $1.5 million, and accretion of discounts on marketable securities of $0.8 million. The change in our net operating assets and liabilities was primarily due to a decrease in prepaid expenses and other assets, an increase in outstanding payables and a decrease in accrued expenses.

Investing Activities

Our investing activities provided $20.8 million of cash during the three months ended March 31, 2026, which consisted primarily of maturities of marketable securities of $31.5 million, partially offset by purchases of marketable securities of $10.7 million.

Our investing activities provided $28.7 million of cash during the three months ended March 31, 2025, which consisted primarily of maturities of marketable securities of $44.4 million, partially offset by purchases of marketable securities of $15.7 million.

Financing Activities

For the three months ended March 31, 2026 and 2025, net cash provided by financing activities was zero.

Critical Accounting Policies and Estimates

The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and judgments that affect the amounts reported in those condensed consolidated financial statements and accompanying notes. Although we believe that the estimates we use are reasonable, due to the inherent uncertainty involved in making those estimates, actual results reported in future periods could differ from those estimates.

We believe that the accounting policies described below involve a high degree of judgment and complexity. Accordingly, these are the policies we believe are the most critical to aid in fully understanding and evaluating our financial condition and results of our operations. During the three-month period ended March 31, 2026, there were no material changes to our critical accounting policies from those described in our audited condensed consolidated financial statements for the year ended December 31, 2025, included in our Annual Report on Form 10-K filed with the SEC on March 6, 2026, except as noted below.

Research and Development Costs, Accrued Research and Development Costs and Related Prepaid Expenses

Research and development costs are expensed as incurred. Research and development expenses consist principally of personnel costs, including salaries, stock-based compensation and benefits for employees, third-party license fees and other operational costs related to our research and development activities, including sourcing of raw materials and manufacturing of our product candidates, allocated facility-related expenses and external costs of outside vendors, and other direct and indirect costs. Non-refundable research and development advance payments are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or services are performed.

As part of the process of preparing our condensed consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule 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 the condensed consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of the estimates with the service providers and make adjustments if necessary. Examples of estimated accrued research and development expenses include fees paid to:

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple research institutions and CROs that supply, conduct and manage preclinical studies and clinical trials on our behalf. 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 vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. 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 the estimate, we adjust the accrual or the prepaid expense accordingly. 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 reporting amounts that are too high or too low in any particular period. To date, there have not been any material adjustments to our prior estimates of accrued research and development expenses.
