Current report

We are obligated to develop and maintain proper and effective internal control over financial reporting. If we fail to develop and maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable laws and regulations could be impaired. In addition, the presence of material weaknesses increases the risk of material misstatement of the consolidated financial statements.

Current report

We are a public company and are required, pursuant to Section 404(a) of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of its internal control over financial reporting on our annual report on Form 10-K. Effective internal control over financial reporting is necessary for reliable financial reports and, together with adequate disclosure controls and procedures, such internal controls are designed to prevent fraud. Undetected material weaknesses in internal controls could lead to financial statement restatements and require us to incur the expense of remediation. We are required to disclose changes made in internal control and procedures on a quarterly basis.

Current report

As discussed elsewhere in this Annual Report, we completed the Merger in April 2024. Prior to the Merger, Trawsfynydd was a private company and, therefore, its controls were not required to be designed or maintained in accordance with Rules 13a-15 and 15d-15 under the Exchange Act. The design and implementation of internal control over financial reporting post-Merger has required, and will continue to require, significant time and resources from management and other personnel. Although we had internal controls in place prior to the Merger, and our management has determined in recent years that such internal controls over financial reporting were effective, during its assessment of our internal controls over financial reporting as of December 31, 2024 it was determined that our controls were not effectively updated and implemented to reflect the changes in processes and staffing during the period between completion of the Merger and December 31, 2024. Additionally, it was determined that there was an inadequate segregation of duties over the preparation, review and posting of manual journal entries, which is the result of not having a sufficient risk assessment process in place post-Merger to identify and analyze risk of misstatement due to fraud and/or error.

Current report

In connection with the audit of our financial statements for the year ended December 31, 2024, we identified material weaknesses in our internal control over financial reporting, which relate to the determinations of management discussed above. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Although we intend to update our controls and implement additional controls, no assurance can be provided that we will be able to remediate the material weaknesses identified on a timely basis, or at all. If we are unable to remedy our material weaknesses, or if we generally fail to establish and maintain effective internal controls appropriate for a public company, we may be unable to produce timely and accurate financial statements, and we may continue to conclude that our internal control over financial reporting is not effective, which could adversely impact our investors’ confidence and our stock price.

Current report

The majority of our cash is held in accounts at U.S. banking institutions. Cash held in depository accounts may exceed the Federal Deposit Insurance Corporation (“FDIC”) standard deposit insurance limit of $250,000. If such banking institutions were to fail, such as Silicon Valley Bank when the FDIC took control in March 2023, we could lose all or a portion of those amounts held in excess of such insured amounts. In the future, our access to our cash in amounts adequate to finance our operations could be significantly impaired if the financial institutions with which we have arrangements encounter liquidity constraints or failures. Any future limitation on timely access to our funds or any material loss that we may experience in the future could have a material adverse effect on our financial condition and could materially impact our ability to pay our operating expenses or make other payments.

Current report

We are currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability and the ongoing military conflicts between Russia and Ukraine and Israel and Hamas. Our business, financial condition and results of operations could be materially adversely affected by any negative impact on the global economy and capital markets resulting from the conflict in Ukraine and the Middle East and/or geopolitical tensions.

Current report

U.S. and global markets are experiencing volatility and disruption, and the global economy has been, and may continue to be, negatively impacted by Russia’s ongoing military conflict with Ukraine. As a result of Russia’s invasion of Ukraine in February 2022, the U.S., the European Union, the United Kingdom, other G7 countries, as well as various

Current report

other countries, have imposed substantial financial and economic sanctions on certain industry sectors and parties in Russia. Broad restrictions on exports to Russia have also been imposed. These measures include: (i) comprehensive financial sanctions against major Russian banks; (ii) additional designations of Russian individuals with significant business interests and government connections; (iii) designations of individuals and entities involved in Russian military activities; and (iv) enhanced export controls and trade sanctions limiting Russia’s ability to import various goods. Russian military actions and the resulting sanctions could continue to adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets, potentially making it more difficult for us to obtain additional funds.

Current report

Addition, in October 2023, Hamas militants and members of certain other organizations infiltrated Israel’s southern border from the Gaza Strip and conducted a series of attacks on civilian and military targets. Shortly thereafter, Israel’s security cabinet declared war against Hamas and launched an aerial bombardment of various targets within the Gaza Strip. It is possible that other countries and/or regional organizations will join the hostilities as well, including without limitation Hezbollah in Lebanon, and Palestinian military organizations in the West Bank, resulting in further expansion of the conflict. The conflict between Israel and Hamas is ongoing, and the length and impact of the ongoing military conflict is highly unpredictable.

Current report

Although our business has not been materially impacted by the ongoing military conflicts between Russia and Ukraine or Israel and Hamas or geopolitical tensions to date, it is impossible to predict the extent to which our operations, or those of our suppliers and manufacturers, will be impacted in the short and long term, or the ways in which the conflict may impact our business. The extent and duration of the conflicts in Ukraine and the Middle East, geopolitical tensions, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions may also magnify the impact of other risks described herein.

Current report

International trade disputes could result in tariffs and other protectionist measures that could have a material adverse effect on our business, financial condition and results of operations.

Current report

In recent years, including after the most recent presidential election, the U.S. has instituted or proposed changes in trade policies that include the negotiation or termination of trade agreements, the imposition of higher tariffs on imports into the U.S., economic sanctions on individuals, corporations or countries, and other government regulations affecting trade between the U.S. and other countries where we conduct our business, in particular China, Mexico and Canada. A number of other nations have proposed or instituted similar measures directed at trade with the United States in response. As a result of these developments, there may be greater restrictions and economic disincentives on international trade that could adversely affect our business. Additionally, tariffs could increase our costs, which could have a negative impact on our financial condition and results of operations. As additional trade-related policies are instituted, we may need to modify our business operations to comply and adapt to such developments, which may be time-consuming and expensive.

Current report

We currently conduct clinical trials, and may in the future choose to conduct additional clinical trials, of our product candidates in sites outside the US, and the FDA may not accept data from trials conducted in foreign locations.

Current report

We currently conduct, and expect in the future to conduct, clinical trials outside the US for our product candidates. The acceptance of study data from clinical trials conducted outside the US or another jurisdiction by the FDA or comparable foreign regulatory authorities may be subject to certain conditions or may not be accepted at all. In cases where data from foreign clinical trials are intended to serve as the sole basis for marketing approval in the US, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the US population and US medical practice; (ii) the trials were performed by clinical investigators of recognized competence and pursuant to GCP regulations; and (iii) the data may be considered valid without the need for an on-site inspection by the FDA, or if the FDA considers such inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. In addition, even where the foreign study data are not intended to serve as the sole basis for approval, if the study was not otherwise subject to an IND, the FDA will not accept the data as support for an application for marketing approval unless the study was conducted in accordance with GCP requirements and the FDA is able to validate the data from the study through an onsite inspection if deemed necessary. Many foreign regulatory authorities have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any comparable foreign regulatory authority will accept data from trials conducted outside of the US or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could be costly and time-consuming, and which may result in current or future product candidates that we may develop not receiving approval for commercialization in the applicable jurisdiction.

Current report

In addition, there are risks inherent in conducting clinical trials in multiple jurisdictions, inside and outside of the US, such as:

Current report

Disruptions at the FDA and foreign regulatory authorities caused by funding shortages, staffing limitations or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, which could negatively impact our business.

Current report

The ability of the FDA and foreign regulatory authorities to review or approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, the FDA’s or foreign regulatory authorities’ ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA’s or foreign regulatory authorities’ ability to perform routine functions including a rapid substantial influx of applications from numerous sponsors, as occurred with COVID-19. Average review times at the FDA and foreign regulatory authorities have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. 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, in recent years, the US government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities.

Current report

Separately, in response to the COVID-19 pandemic, the FDA postponed most inspections of domestic and foreign manufacturing facilities at various points. If a prolonged government shutdown occurs, or funding shortages, staffing limitations, or renewed global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities on a timely basis, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

Current report

For example, large pharmaceutical companies such as Roche, GSK and BioCryst Partners successfully market the commercialized anti-influenza drugs neuraminidase inhibitors oseltamivir phosphate (Tamiflu), zanamivir (Relenza), and peramivir (Rapivab) anti-influenza drugs, respectively. Additionally, Roche’s antiviral, baloxavir marboxil (Xofluza), a CEN inhibitor, is also approved for the treatment of influenza. Gilead, Pfizer and Merck have commercialized drugs for the management of COVID-19 in certain populations, including remdesivir and, nirmatrelvir + ritonavir, or molnupiravir, respectively.

Risk Factors Relating to the Merger

Current report

As discussed elsewhere in this Annual Report, in April 2024, we merged with Trawsfynydd. We cannot guarantee that implementing the Merger and related transactions will not impair stockholder value or otherwise adversely affect our business. The Merger continues to pose integration challenges between our businesses and management teams, which could result in management and business disruptions, any of which could harm our results of operation, business prospects, and impair the value of the Merger to our stockholders.

Current report

Stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger, including the issuance of our common stock upon conversion of all outstanding shares of our Series C Preferred issued in the Merger and Financing.

Current report

If we are unable to realize the full strategic and financial benefits currently anticipated from the Merger, stockholders will have experienced substantial dilution of their ownership interests without receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent we are able to realize only part of the strategic and financial benefits currently anticipated from the Merger.

Current report

The failure to successfully integrate the businesses of Onconova and Trawsfynydd in the expected timeframe would adversely affect Traws Pharma’s future results.

Current report

Our ability to successfully integrate the operations of Onconova and Trawsfynydd will depend, in part, on our ability to realize the anticipated benefits from the Merger. If we are not able to achieve these objectives within the anticipated time frame, or at all, the anticipated benefits of the Merger may not be realized fully, or at all, or may take longer to realize than expected, and the value of our common shares may be adversely affected. In addition, the integration of the Company’s and Trawsfynydd’s respective businesses has been, and will likely continue to be, a time-consuming and expensive process. Proper planning and effective and timely implementation will be critical to avoid any significant disruption to Traws Pharma’s operations. It is possible that the continuing integration process could result in the loss of key employees, the disruption of our ongoing business or the identification of inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with suppliers, distributors, creditors, lessors, clinical trial investigators or managers or to achieve the anticipated benefits of the Merger. Delays encountered in the integration process could have a material adverse effect on Traws Pharma’s revenues, expenses, operating results and financial condition, including the value of its common shares.

Current report

As a result of the Merger, we have become a more diversified company and our business has become more complex. There can be no assurance that we will effectively manage the increased complexity without experiencing operating inefficiencies or control deficiencies. Significant management time and effort is required to effectively manage our increased complexity and our failure to successfully do so could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

Current report

We expect to incur substantial expenses related to the integration of Trawsfynydd.

Current report

We have incurred, and expect to continue to incur, substantial expenses in connection with the Merger and the integration of Trawsfynydd. There are a large number of processes, policies, procedures, operations, technologies and systems that must be integrated, including purchasing, accounting and finance, billing, payroll, research and development, marketing and benefits. Both the Company and Trawsfynydd incurred significant transaction expenses in connection with the drafting and negotiation of the Merger Agreement, the Stock Purchase Agreement and the related ancillary agreements and significant severance expenses in connection with the reduction of employees in April 2024. While we have assumed that a certain level of expenses will be incurred, there are many factors beyond our control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These integration expenses likely will result in our taking significant charges against earnings following the completion of the Merger, and the amount and timing of such charges are uncertain at present.

Current report

We have entered into certain related party transactions and may continue to rely on related parties for certain development and support activities.

Current report

We have entered into, and may continue to enter into, transactions with related parties for certain development and support activities. For example, we have entered into master research and development agreements with ChemDiv, Inc. and Viriom, Inc., both of which are related parties, to provide certain research and development related services for virology product candidates. For additional information related to these and other related party transactions, please see Note 12, Research and Development Arrangements and Related Party Transactions, to our consolidated financial statements included in Part IV in this Annual Report. Such related party transactions may not have been entered into on an arm’s-length basis, and we may have achieved more favorable terms because such transactions were entered into with our related parties. We rely on, and will continue to rely on, our related parties to maintain these services. If the pricing for these services changes, or if our related parties cease to provide these services, including by terminating agreements with us, we may be unable to obtain replacements for these services on the same terms without disruption to our business. This could have a material effect on our business, results of operations and financial condition.

Current report

We may be required to raise additional financing by issuing new securities with terms or rights superior to those of our existing securityholders, which could adversely affect the market price of shares of common stock and our business.

Current report

We will require additional financing to fund future operations, including for research and development, clinical trials, expansion in current and new markets, development and acquisition, capital costs and the costs of any necessary implementation of technological innovations or alternative technologies. We may not be able to obtain financing on favorable terms, if at all. If we raise additional funds by issuing equity securities, the percentage ownership of our current stockholders will be reduced, and the holders of the new equity securities may have rights superior to those of our existing securityholders, which could adversely affect the market price of our common stock and the voting power of shares of our common stock. If we raise additional funds by issuing debt securities, the holders of these debt securities would similarly have some rights senior to those of our existing securityholders, and the terms of these debt securities could impose restrictions on operations and create a significant interest expense for us which could have a materially adverse effect on our business.

Current report

Our common stock is listed on the Nasdaq Capital Market (“Nasdaq”), a national securities exchange, which imposes continued listing requirements with respect to issuers whose securities are listed on Nasdaq. If we fail to satisfy the continued listing standards, such as, for example, Nasdaq’s minimum bid price requirement or stockholders equity requirements, Nasdaq may issue a non-compliance letter or initiate delisting proceedings.

Current report

As previously disclosed, on November 20, 2024, we received a letter from the staff (the “Staff”) of the Listing Qualifications Department of Nasdaq notifying us that the Company was no longer in compliance with the minimum $2.5 million stockholders’ equity requirement for continued listing on Nasdaq as set forth in Listing Rule 5550(b)(1) (the “Rule”). After a hearing, the Nasdaq Hearings Panel granted the Company an exception until February 18, 2025 to demonstrate compliance with the Nasdaq listing rules. On February 25, 2025, we received a letter from Nasdaq confirming that the Company had regained compliance with the Rule. Pursuant to Listing Rule 5815(d)(4)(B), the Company will be subject to a mandatory panel monitor for a period of one year from the date of such letter. If, within that one-year monitoring period, the Staff finds that the Company is no longer in compliance with the Rule, then, notwithstanding Rule 5810(c)(2), we will not be permitted to provide the Staff with a plan of compliance with respect to such deficiency and the Staff will not be permitted to grant additional time for us to regain compliance with respect to such deficiency, nor will we be afforded an applicable cure or compliance period pursuant to Rule 5810(c)(3). Instead, the Staff will issue a Delist Determination Letter and we will have an opportunity to request a new hearing with the initial Hearings Panel or a newly convened Hearings Panel if the initial Hearings Panel is unavailable.

Current report

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal controls. In addition, we are required to furnish a report by management on the effectiveness of our internal control over financial reporting, pursuant to Section 404 of the Sarbanes-Oxley Act. As discussed elsewhere in this Annual Report, as of December 31, 2024, based on an analysis completed by management, our internal controls were not effective due to the existence of material weaknesses. The process of designing, implementing and testing the internal control over financial reporting required to comply with this obligation is time-consuming, costly and complicated. If we identify material weaknesses in our internal control over financial reporting (as we have for the period covered by this Annual Report), if we are unable to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to assert that our internal control over financial reporting is effective, investors may lose confidence in the accuracy and completeness of our financial reports and the market price of our common stock could decline, and we could also become subject to investigations by the stock exchange on which our common stock is listed, the Commission or other regulatory authorities, which could require additional financial and management resources.

Current report

Future issuances of stock or other securities could dilute the holdings of stockholders and could materially affect the price of the shares of our common stock.

Current report

As discussed elsewhere in this Annual Report, we will need to obtain additional financing in the future to carry out our business objectives. We may do so through the sale and issuance of shares of our common stock or securities convertible or exercisable for shares of our common stock. Additionally, there are currently warrants to purchase an aggregate of 5,848,082 shares of our common stock outstanding and shares of Series C Preferred Stock convertible into an aggregate of 2,959,158 shares of our common stock outstanding. Any issuance of shares of our common stock, including upon the exercise or conversion of outstanding warrants and shares of Series C Preferred, respectively, or issuance of securities exercisable for or convertible into shares of our common stock, will result in the dilution of the ownership interests of our existing stockholders. Additionally, the issuance of a significant number of shares of our common stock could result in a decrease in the price of our common stock.

Current report

We have used and intend to continue to use equity incentives for employees, advisors, directors, key consultants and select affiliates. Any issuance of stock upon the conversion of options, restricted stock units and/or other incentive rights will result in the dilution of the ownership interests of our existing stockholders.

Previous report

Our consolidated financial statements for the year ended December 31, 2023 have been prepared assuming we will continue to operate as a going concern. However, due to our ongoing operating losses and our accumulated deficit, management has concluded that there is substantial doubt about our ability to continue as a going concern for the next twelve months from the date of the financial statements included in this Annual Report on Form 10-K. Because we continue to experience net operating losses, our ability to continue as a going concern is subject to our ability to

Previous report

successfully raise sufficient additional capital, through future financings or through strategic and collaborative arrangements. If we are unable to obtain additional funding, we may not be able to continue as a going concern.

Previous report

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation, or the FDIC, as receiver, and created uncertainty and liquidity concerns for us, at that time, and in the broader financial services industry remain. There is no guarantee that a similar event will not occur again and that our liquidity will not be adversely affected.

Previous report

We are required to meet certain qualitative and financial tests to maintain the listing of our securities on the Nasdaq Capital Market (Nasdaq). As of March 25, 2024, we were not in compliance with the Nasdaq continued listing requirements related to minimum bid price.​

Previous report

On September 25, 2023, we received a letter from Nasdaq indicating that we failed to comply with the minimum bid price requirement of Nasdaq Listing Rule 5550(a)(2), which requires that companies listed on Nasdaq maintain a minimum closing bid price of at least $1.00 per share.​

Previous report

Under Nasdaq Listing Rule 5810(c)(3)(A), we had a 180 calendar day grace period, or until March 25, 2024, to regain compliance by meeting the continued listing standard. The continued listing standard will be met if the Company’s common stock has a minimum closing bid price of at least $1.00 per share for a minimum of ten consecutive business days during the 180-calendar day grace period.​

Previous report

We did not regain compliance with the minimum bid price requirement by March 25, 2024. On March 27, 2024, we received a letter from Nasdaq granting the Company a second 180 calendar day period to regain compliance under Nasdaq Listing Rule 5810(c)(3)(A), or until September 23, 2024. Their determination to grant the second compliance period was based on our meeting the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, except for the minimum bid price requirement, and our notification to Nasdaq of its intention to cure the minimum bid price deficiency during the second compliance period, by effecting a reverse stock split, if necessary.

Previous report

If we do not regain compliance by September 25, 2024, Nasdaq will provide notice that the Company’s common stock will be delisted. At that time, we may appeal the Nasdaq staff’s determination to a Nasdaq Hearings Panel.​

Previous report

We intend to monitor the closing bid price of the Company’s common stock and continue to consider our available options to resolve the noncompliance with the minimum bid price requirement.

Previous report

There can be no assurance that we will be able to regain compliance with the minimum bid price requirement or will otherwise be in compliance with other Nasdaq listing criteria.

Previous wording

Management has concluded that substantial doubt exists about our ability to continue as a going concern for the next twelve months from the date of the financial statements included in this Annual Report on Form 10-K. As of December 31, 2023, we had cash and cash equivalents of $20.8 million and current liabilities of $9.2 million. We believe that we have sufficient resources available to support our development activities and business operations and satisfy our obligations into the third quarter of 2024. We do not have sufficient cash and cash equivalents as of the date of this Annual Report on Form 10-K to support our operations for at least the 12 months following the date that the financial statements are issued.

Current wording

Management has concluded that substantial doubt exists about our ability to continue as a going concern for the next twelve months from the date of the financial statements included in this Annual Report. As of December 31, 2024, we had cash and cash equivalents of $21.3 million and current liabilities of $11.5 million. Based on current projections, we do not have sufficient cash and cash equivalents as of the date of this Annual Report to support our operations for more than one year following the date that the financial statements are issued.

Previous wording

The auditor’s opinion on our audited financial statements for the year ended December 31, 2023 includes an explanatory paragraph stating that we have incurred recurring losses from operations that raise substantial doubt about our ability to continue as a going concern for the next twelve months from the date of the financial statements included in this Annual Report on Form 10-K. While we believe that we will be able to raise the capital we need to continue our operations, there can be no assurances that we will be successful in these efforts or will be able to resolve our liquidity issues or eliminate our operating losses. If we are unable to obtain sufficient funding, we would need to significantly reduce our operating plans and curtail some or all of our development efforts. Accordingly, our business, prospects, financial condition, and results of operations will be materially and adversely affected, and we may be unable to continue as a going concern. If we seek additional financing to fund our business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding on commercially reasonable terms or at all.

Previous wording

We do not have the funding resources necessary to carry out all of our proposed operating activities. We will need to obtain additional financing in the future in order to fully fund narazaciclib, rigosertib or any other product candidates through the regulatory approval process. Accordingly, we may delay or pause our planned clinical trials, until we secure adequate additional funding. If we seek to proceed with a clinical trial without additional funding, we may receive questions or comments from the FDA, fail to obtain IRB approval, or find it more difficult to enroll patients in the trial. We have scaled down our operations in order to reduce spending on general and administrative functions, research and development, and other clinical trials, but by themselves, those measures may not be sufficient to address our funding needs.

Current wording

We do not currently have the funding resources necessary to carry out all of our proposed operating activities. We will need to obtain additional financing in the future in order to fully fund tivoxavir marboxil, ratutrelvir, narazaciclib, rigosertib or any other product candidates through the regulatory approval process. Accordingly, we may be required to delay or pause our planned clinical trials until we secure adequate additional funding.

We have scaled down our operations in order to reduce spending on general and administrative functions, research and development, and other clinical trials, but by themselves, those measures may not be sufficient to address our funding needs.

We are a clinical-stage biopharmaceutical company. Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that a product candidate could fail to gain regulatory approval or become commercially viable. We do not have any products approved by regulatory authorities for marketing and have not generated any revenue from product sales to date, and we continue to incur significant research, development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred losses in every reporting period since our inception in 1998. For the years ended December 31, 2023, and 2022, we reported net losses of $18.9 million and $19.0 million, respectively, and we had an accumulated deficit of $482.6 million at December 31, 2023.

In addition, because of the numerous risks and uncertainties associated with product development, including that our product candidates may not advance through development or achieve the endpoints of applicable clinical trials, we are unable to predict the timing or amount of increased expenses, or when or if we will be able to achieve or maintain profitability. Even if we are able to complete the development and regulatory process for any product candidates, we anticipate incurring significant costs associated with commercializing these products. Even if we are able to generate revenues from the sale of our products, we may not become profitable and may need to obtain additional funding to continue operations. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or suspend our operations.

Clinical and non-clinical development is expensive, time-consuming, and uncertain as to the outcome. The focus of our development efforts is currently on narazaciclib and oral rigosertib. Although, we believe that there are opportunities for us to develop narazaciclib, our novel multi kinase inhibitor targeting CDK4/6 as well as other tyrosine kinases, in indications such as endometrial cancer, metastatic breast cancer, mantle cell lymphoma and multiple myeloma, and oral rigosertib in RAS mutated cancers, clinical drug development is expensive, can take many years to complete, and its outcome is inherently uncertain. Even if our clinical development programs are successful, we may not be able to successfully commercialize any product.

Encouraging results in preclinical testing and earlier clinical studies do not ensure that later clinical trials will generate adequate data to demonstrate the efficacy and safety of an investigational drug. Additionally, mechanisms of action, studies in small or single patient populations, and interim study results may not be predictive of later stage studies. The development of a product for one indication may further impact its development for other indications. By example, our phase III study of intravenous rigosertib for HR MDS did not meet its primary endpoints. It is possible that this may impact how regulators or others view the development of rigosertib for alternative indications and via different methods of administration. If later-stage clinical trials do not produce favorable results, our ability to achieve regulatory approval for any of our product candidates may be adversely impacted.

Where we have the right to do so under our license agreements, we seek to protect our proprietary position by filing patent applications in the United States and abroad related to our novel technologies and products that are important to our business. The patent positions of biotechnology and pharmaceutical companies generally are highly uncertain, involve complex legal and factual questions and have in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patents, including those patent rights licensed to us by third parties, are highly uncertain.

Previous wording

rights already granted under any of our currently issued patents and those that may be granted under future issued patents may not provide us with the proprietary protection or competitive advantages we are seeking. If we are unable to obtain and maintain patent protection for our technology and products, or if the scope of the patent protection obtained is not sufficient, our competitors could develop and commercialize technology and products similar or superior to ours, and our ability to successfully commercialize our technology and products may be adversely affected.

Current wording

The steps we have taken to protect our proprietary rights may not be adequate to preclude misappropriation of our proprietary information or infringement of our intellectual property rights, both inside and outside the United States. The rights already granted under any of our currently issued patents and those that may be granted under future issued patents may not provide us with the proprietary protection or competitive advantages we are seeking.

Previous wording

Even if patents are granted that cover commercially valuable compounds, we may decide to allow such patents to lapse, or if in-licensed, return the patents to the licensor. The effects of doing so are uncertain. In the case of returning granted patents to a licensor, we may encounter a scenario in which we need the patents in the future and are unable to obtain a new license to such patents on commercially reasonable terms or at all. The licensor may license the returned patents to a competitor, who may then enforce the patents against us. In the first quarter of 2023, we returned a portion of the patents that we in-licensed from Temple University back to Temple. The long-term economic effects of doing so are uncertain.

before the USPTO. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future. If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue developing and commercializing our products and technology. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, in any such proceeding or litigation, we could be found liable for monetary damages. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could materially harm our business. Any claims by third parties that we have misappropriated their confidential information or trade secrets could have a similar negative impact on our business.

Current wording

Our commercial success depends upon our ability and the ability of our collaborators to develop, manufacture, market and sell our product candidates, and to use our proprietary technologies without infringing the proprietary rights of third parties. We may become party to, or threatened with, future adversarial proceedings or litigation regarding intellectual property rights with respect to our products and technology, including interference or derivation proceedings before the USPTO.

Previous wording

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, who are responsible for appointing the members of our management. Because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which may discourage, delay or prevent someone from acquiring us or merging with us whether or not it is desired by or beneficial to our stockholders. Under Delaware law, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other things, the board of directors has approved the transaction. Any provision of our amended and restated certificate of incorporation or amended and restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.
