Current report
Management has performed an analysis and concluded that there exists a substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing on terms acceptable to us, if at all.
Current report
Our financial statements as of December 31, 2025 have been prepared under a going concern basis. Management has performed an analysis and concluded that there exists a substantial doubt about our ability to continue as a going concern. Separately, our independent registered public accounting firm included in its opinion for the year ended December 31, 2025 an explanatory paragraph referring to our recurring losses from operations and expressing substantial doubt in our ability to continue as a going concern without additional capital becoming available. Our ability to continue as a going concern is dependent upon our ability to obtain additional equity or debt financing, obtain government grants or reduce expenditures. Our financial statements as of December 31, 2025 did not include any adjustments that might result from the outcome of this uncertainty. The reaction of investors to the inclusion of a going concern statement in the accompanying financial statement, and our potential inability to continue as a going concern, in future years could materially adversely affect our share price and our ability to raise new capital or enter into strategic alliances.
Current report
We rely heavily on third-party consultants and advisors to support key aspects of our operations, including research and development, regulatory strategy, clinical trial management, manufacturing, quality assurance, and business development. These consultants are not our employees and may have commitments to other organizations, which could limit their availability to us. If we are unable to retain these consultants, replace them on commercially reasonable terms, or effectively manage their performance, our development programs, regulatory submissions, and overall business operations could be delayed or adversely affected. In addition, we have limited control over the timing, quality, and outcomes of the services provided by third-party consultants, and any failure by such consultants to perform in accordance with applicable regulatory standards or contractual obligations could expose us to reputational harm, increased costs, or regulatory enforcement actions.
Current report
The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the FDA and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.
Current report
Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical employees and stop critical activities. If a prolonged government shutdown occurs, or if global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.
Current report
On February 18, 2026, Nerviano sent us a written notice alleging that we are in material breach of the Nerviano Agreement with respect to (i) alleged joint ownership of certain of our patents and (ii) the filing of a joint invention continuation patent application. We are currently evaluating the notice and intend to respond within the applicable cure period set forth in the Nerviano Agreement. If we are unable to cure the alleged breach or successfully dispute the alleged breach within the applicable cure period, Nerviano may exercise its right to terminate the Nerviano Agreement. Any such termination would result in the loss of our license rights to onvansertib and any other intellectual property licensed thereunder, which would have a material adverse effect on our business, financial condition, results of operations, and prospects.
Current report
In July 2025, the OBBBA was signed into law, and it (along with other recent U.S. federal tax reform) has resulted in significant changes to the taxation of business entities including, among other changes, changes to the taxation of income derived from international operations, changes in the deduction and amortization of research and development expenditures, and limitations on the deductibility of business interest. Future guidance from the Internal Revenue Service and other tax authorities with respect to any legislation may affect us, and certain aspects of such legislation could be repealed or modified or sunset in future years.
Removed paragraphs (2)
Previous report
U.S. federal income tax reform could adversely affect us.
Previous report
On December 22, 2017, President Trump signed into law the TCJA that significantly reforms the Internal Revenue Code of 1986, as amended. The TCJA, among other things, includes changes to U.S. federal tax rates, imposes significant additional limitations on the deductibility of interest, allows for the expensing of capital expenditures, and puts into effect the migration from a “worldwide” system of taxation to a territorial system. We do not expect tax reform to have a material impact to our projection of minimal cash taxes or to our net operating losses. Further, any eligibility we may have or may someday have for tax credits associated with the qualified clinical testing expenses arising out of the development of orphan drugs will be reduced to 25% as a result of the TCJA; thus, our net future taxable income may be affected. We continue to examine the impact this tax reform legislation may have on our business. The impact of this tax reform on holders of our common stock is uncertain and could be adverse.
Reworded paragraphs (8)
Previous wording
We are a clinical stage company and have incurred losses since our formation. As of December 31, 2024, we have an accumulated total deficit of approximately $384.2 million. For the fiscal years ended December 31, 2024 and 2023, we had a net loss attributable to common stockholders of approximately $45.5 million and $41.5 million, respectively. To date, we have experienced negative cash flow from development of our product candidate, onvansertib. We have generated limited revenue from operations, and we expect to incur substantial net losses for the foreseeable future as we seek to further develop and commercialize onvansertib. We cannot predict the extent of these future net losses, or when we may attain profitability, if at all. If we are unable to generate significant revenue from onvansertib or attain profitability, we will not be able to sustain operations.
Current wording
We are a clinical stage company and have incurred losses since our formation. As of December 31, 2025, we have an accumulated total deficit of approximately $430.0 million. For the fiscal years ended December 31, 2025 and 2024, we had a net loss attributable to common stockholders of approximately $45.9 million and $45.5 million, respectively. To date, we have experienced negative cash flow from development of our product candidate, onvansertib.

Previous wording
As of December 31, 2024, our cash, cash equivalents and short-term investments balance was approximately $91.7 million and our working capital was approximately $81.6 million. Due to our recurring losses from operations and the expectation that we will continue to incur losses in the future, we will be required to raise additional capital to complete the development and commercialization of our current product candidate. We have historically relied upon private and public sales of our equity, as well as debt financings to fund our operations. In order to raise additional capital, we may seek to sell additional equity and/or debt securities or obtain a credit facility or other loan, which we may not be able to do on favorable terms, or at all. Our ability to obtain additional financing will be subject to a number of factors, including market conditions, our operating performance and investor sentiment. If we are unable to raise additional capital when required or on acceptable terms, we may have to significantly delay, scale back or discontinue the development and/or commercialization of our product candidate, restrict our operations or obtain funds by entering into agreements on unfavorable terms. Failure to obtain additional capital at acceptable terms would result in a material and adverse impact on our operations.

Previous wording
Our product candidate, onvansertib, is in the early stages of clinical development and its commercial viability remains subject to current and future preclinical studies, clinical trials, regulatory approvals and the risks generally inherent in the development of a pharmaceutical product candidate. If we are unable to successfully advance or develop our product candidate, our business will be materially harmed.
Current wording
Our product candidate, onvansertib, is in the early-mid stages of clinical development and its commercial viability remains subject to current and future preclinical studies, clinical trials, regulatory approvals and the risks generally inherent in the development of a pharmaceutical product candidate. If we are unable to successfully advance or develop our product candidate, our business will be materially harmed.
Previous wording
Furthermore, we have adopted an operating model that largely relies on the outsourcing of a number of responsibilities and key activities to third-party consultants, and contract research and manufacturing organizations in order to advance the development of our product candidate. Therefore, our success depends in part on our ability to retain highly qualified key management, personnel, and directors to develop, implement and execute our business strategy, operate the company and oversee the activities of our consultants and contractors, as well as academic and corporate advisors or consultants to assist us in this regard. We are currently highly dependent upon the efforts of our management team. In order to develop our product candidate, we need to retain or attract certain personnel, consultants or advisors with experience in drug development activities that include a number of disciplines, including research and development, clinical trials, medical matters, government regulation of pharmaceuticals, manufacturing, formulation and chemistry, business development, accounting, finance, regulatory affairs, human resources and information systems. We are highly dependent upon our senior management and scientific staff, particularly Mark Erlander, our Chief Executive Officer (“CEO”). The loss of services of Dr. Erlander or one or more of our other members of senior management could delay or prevent the successful completion of our planned clinical trials or the commercialization of our product candidate.

Previous wording
We do not own or operate any manufacturing facilities. We intend to rely on GMP, FDA validated third-party contractors, at least for the foreseeable future, to formulate and manufacture these preclinical and clinical materials. Our reliance on third-party contract manufacturers exposes us to a number of risks, any of which could delay or prevent the completion of our preclinical studies or clinical trials, or the regulatory approval or commercialization of our product candidate, result in higher costs, or deprive us of potential product revenues. Some of these risks include:

We are a small company with 33 employees as of December 31, 2024. Future growth of our company will impose significant additional responsibilities on members of management, including the need to identify, attract, retain, motivate and integrate highly skilled personnel. We may increase the number of employees in the future depending on the progress of our development of our product candidate. Our future financial performance and our ability to commercialize our product candidate and to compete effectively will depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to:

Previous wording
The cost of prescription pharmaceuticals in the United States has also been the subject of considerable discussion. There have been several Congressional inquiries and proposed bills designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. Most recently, on August 16, 2022, the Inflation Reduction Act of 2022 (IRA) was signed into law. Among other things, the IRA requires manufacturers of certain drugs to engage in price negotiations with Medicare (beginning in 2026), with prices that can be negotiated subject to a cap; imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation (first due in 2023); and replaces the Part D coverage gap discount program with a new discounting program (beginning in 2025). The IRA permits the Secretary of the Department of Health and Human Services (HHS) to implement many of these provisions through guidance, as opposed to regulation, for the initial years. For that and other reasons, it is currently unclear how the IRA will be effectuated.

For that and other reasons, it is currently unclear how the IRA will be effectuated. Additionally, in April 2025, an executive order was signed directing the Secretary of HHS to take appropriate steps to, among other things, modify certain provisions of the Medicare Drug Price Negotiation Program, develop and implement a payment model to reduce the price of high-cost prescription drugs and biological products covered by Medicare, accelerate approval of generic and biosimilar products, and facilitate the ability of states to import pharmaceuticals from other countries, and in May 2025, an executive order was signed, among other things, directing the Secretary of HHS to propose rules that impose “most-favored-nation” pricing and take other measures to reduce the cost of prescription drugs. It is currently unclear whether and to what extent these measures will be implemented and what impact any such implementation would have on our business. Further, there can be no assurance that the current administration or future administrations will not pursue different or additional measures, such as those intended to more closely align U.S. drug prices with international drug prices (often referred to as “reference” or “international price index” drug pricing). Future price controls or other changes in pricing regulation or negative publicity related to the pricing of pharmaceutical drugs could restrict the amount that we are able to charge for our product candidates, which could render our product candidates, if approved, commercially unviable and materially adversely affect our ability to raise additional capital on acceptable terms.

The market price of our common stock historically has been, and we expect will continue to be, subject to significant fluctuations over short periods of time. For example, during the year ended December 31, 2024, the closing price of our common stock ranged from a low of $1.46 to a high of $5.91. These fluctuations may be due to various factors, many of which are beyond our control, including:
