Current report

Our future success depends on our ability to identify, acquire or license new drug candidates, and we may not be successful in doing so.

Current report

A key element of our business strategy is to expand our pipeline by acquiring or licensing rights to additional drug candidates from third parties. The success of this strategy depends on our ability to identify, evaluate and acquire or license suitable drug candidates on commercially reasonable terms. Competition for attractive drug candidates is intense, and many of our competitors have substantially greater financial, technical and human resources than we do, which may limit our ability to identify and acquire promising therapeutic assets.

Current report

We may not be able to identify drug candidates that meet our strategic criteria or that we believe have sufficient probability of clinical and commercial success. Even if we identify promising candidates, we may not be able to negotiate acquisition or licensing terms that are acceptable to us, or we may be outbid by competitors with greater resources. Additionally, due diligence evaluations of potential acquisition or licensing targets may not reveal all relevant risks, liabilities or issues, and we may acquire or license drug candidates that ultimately prove to be less valuable or more problematic than anticipated.

Current report

If we are unable to successfully identify and acquire or license new drug candidates, our pipeline may remain limited, which could materially and adversely affect our business, financial condition, results of operations and prospects.

Current report

Any drug candidates we acquire or license may require significant additional development, and there can be no assurance that such candidates will prove to be safe, effective or commercially viable.

Current report

Even if we are successful in acquiring or licensing new drug candidates, such candidates will likely require substantial additional investment and development before they could potentially receive regulatory approval and be commercialized. Drug development is inherently risky and uncertain. Many drug candidates fail to demonstrate adequate safety or efficacy in clinical trials, and there can be no assurance that any drug candidate we acquire or license will be successfully developed, receive regulatory approval or achieve commercial success.

Current report

In addition, drug candidates we acquire or license may have unknown liabilities, intellectual property defects or other issues that were not identified during our due diligence evaluation. We may also face challenges integrating newly acquired or licensed assets into our organization and development programs. Any of these factors could result in significant delays, increased costs or failure of our development programs, which could materially and adversely affect our business, financial condition and results of operations.

Current report

We may not have access to sufficient capital to pursue acquisition or licensing opportunities, which could limit our ability to expand our pipeline.

Current report

Acquiring or licensing drug candidates often requires significant upfront payments, milestone payments, royalty obligations and ongoing development costs. As a clinical-stage company with limited financial resources, we may not have access to sufficient capital to pursue attractive acquisition or licensing opportunities when they arise. Our ability to raise additional capital may be limited by market conditions, investor sentiment, our financial performance and other factors beyond our control.

Current report

If we are unable to raise sufficient capital on acceptable terms, we may be forced to forgo attractive acquisition or licensing opportunities, reduce the scope of our business development activities or delay or discontinue development of drug candidates we have already acquired. Any of these outcomes could limit our ability to expand our pipeline and materially harm our business and prospects.

Current report

Under our new corporate strategy, we will seek to obtain rights to new investigational product candidates, which could include upfront cash payments, milestone payments, royalties, issuing shares of our stock, assuming liabilities or a combination of any of these considerations. It is possible that any of these considerations may be greater than our currently available resources and require that we undertake additional financings or issue additional equity or debt securities. We are also evaluating TPI 287 and Berubicin as we explore the potential out-licensing of these programs but there can be no assurances that we will be able to successfully complete an out-licensing transaction. Potential licensors may require additional preclinical or clinical data, CMC data, intellectual property or other considerations before undertaking a transaction. We may determine that the generation of additional preclinical or clinical data, CMC data or new intellectual property is not feasible or cost prohibitive relative to potential financial considerations we could potentially receive and we may instead elect to sunset TPI 287, Berubicin or both programs.
Removed paragraphs (7)

Previous report

Our success depends greatly on the success of TPI 287 and Berubicin’s development for the treatment of glioblastoma, and our pipeline of product candidates beyond this lead indication is extremely early stage and limited.

Previous report

Other than TPI 287 and Berubicin, we do not have any other clinical-stage drug candidates in our portfolio. As such, we are dependent on the success of TPI 287 and Berubicin in the near term. We cannot provide you any assurance that we will be able to successfully advance TPI 287 and Berubicin through the development process or that we will be able to secure other additional assets for development.

Previous report

Our chief science officer is currently working for us on a part-time basis. Our chief executive officer and chief science officer, also provide services for other companies in our industry and such other positions may create conflicts of interest for such officers in the future.

Previous report

Certain of our key employees are currently part-time and/or provide services for other biotechnology development efforts, including companies, with respect to our chief executive officer and chief science officer, which are developing anti-cancer drug candidates. Specifically, John M. Climaco, our chief executive officer, is also serving as a director for Moleculin Biotech, Inc., a company also actively developing anticancer drugs. Donald Picker, our chief science officer, is the chief scientific officer at Moleculin.

Previous report

In addition to our officers’ part-time status, since Mr. Climaco and Dr. Picker are associated with other companies that are developing anti-cancer drug candidates, they may encounter conflicts of interest in the future. Although we do not believe that the drug candidates we are currently pursuing compete with the types of drug candidates being pursued by the other companies Mr. Climaco and Dr. Picker are associated with, there is no assurance that such conflicts will not arise in the future.

Previous report

We intend to take advantage of all of these reduced reporting requirements and exemptions, other than the longer phase-in periods for the adoption of new or revised financial accounting standards under §107 of the JOBS Act.

Previous report

We cannot predict if investors will find our securities less attractive due to our reliance on these exemptions. If investors were to find our common stock less attractive as a result of our election, we may have difficulty raising financing in the future.
Reworded paragraphs (27)

Previous wording

We will require substantial funding to complete our clinical trials, which may not be available to us on acceptable terms, or at all, and, if not so available, may require us to delay, limit, reduce or cease our operations.

Current wording

We will require substantial funding to execute our new corporate strategy, which may not be available to us on acceptable terms, or at all, and, if not so available, may require us to delay, limit, reduce or cease our operations.

Previous wording

We have used the proceeds from our previous financings to, among other uses, advance Berubicin through clinical development. Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We will require substantial additional future capital in the near term in order to complete clinical development and commercialize TPI 287 and Berubicin. If the FDA requires that we perform additional nonclinical studies or clinical trials, our expenses would further increase beyond what we currently expect and the anticipated timing of any potential approval of TPI 287 and Berubicin would likely be delayed. Further, there can be no assurance that the costs we will need to incur to obtain regulatory approval of TPI 287 and Berubicin will not increase.

Current wording

We have primarily used the proceeds from our previous financings to, among other uses, advance Berubicin through clinical development. In addition, we used proceeds from our previous financings to obtain the rights to TPI 287. Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive.

Previous wording

We will continue to require substantial additional capital to continue our clinical development and commercialization activities. Because successful development of our product candidates is uncertain, we are unable to estimate the actual amount of funding we will require to complete research and development and commercialize our products under development.

Current wording

We will continue to require substantial additional capital to execute in-licensing to expand our pipeline, clinical development and commercialization activities. Because successful development of our product candidates is uncertain, we are unable to estimate the actual amount of funding we will require to complete research and development and commercialize our products under development.

Previous wording

We estimate that we have sufficient capital to take us into the first quarter of 2026, a period during which we would likely expect to initiate a trial of TPI 287, as well as complete the Phase 2 Berubicin trial including its further analysis. In addition, we have working capital to fund our operations during this period (with such operations estimated at $4.5 to $5.0 million per annum). We do not currently have a firm trial design for TPI 287 so estimates of development cost are not available, however, regardless of trial design, the cost of bringing TPI 287 to regulatory approval for marketing will require significant additional financing. The timing and costs of clinical trials are difficult to predict and as such the foregoing estimates may prove to be inaccurate. We have no commitments for such additional needed financing and will likely be required to raise such financing through the sale of additional equity or debt securities.

Current wording

We estimate that we have sufficient capital to fund operations into the third quarter of 2026. We have no commitments for such additional needed financing and will likely be required to raise such financing through the sale of additional equity or debt securities.

Previous wording

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail one or more of our research or development programs. We also could be required to seek funds through arrangements with collaborative partners or otherwise that may require us to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us.

Current wording

If we are unable to obtain funding on a timely basis, we may not be able to execute on our in-licensing focused strategy. We also could be required to seek funds through arrangements with collaborative partners or otherwise that may require us to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us.

Previous wording

We have never been profitable and do not expect to be profitable in the foreseeable future. We have not yet submitted any drug candidates for approval by regulatory authorities in the United States or elsewhere. Our ability to continue as a going concern is dependent upon our generating cash flow from sales that are sufficient to fund operations or finding adequate financing to support our operations. To date, we have had no revenues and have relied on equity-based financing from the sale of securities in public and private placements and the issuance of convertible notes. The continuation of the Company as a going concern is dependent upon our ability to obtain necessary equity or debt financing to continue operations and the attainment of profitable operations. As of December 31, 2024 the Company has incurred an accumulated deficit of $84,424,704 since inception and had not yet generated any revenue from operations. Additionally, management anticipates that its cash on hand as of December 31, 2024, combined with capital raised subsequent to December 31, 2024, is sufficient to fund its planned operations within one year after the date that the financial statements are issued.

The continuation of the Company as a going concern is dependent upon our ability to obtain necessary equity or debt financing to continue operations and the attainment of profitable operations. As of December 31, 2025 the Company has incurred an accumulated deficit of $100,275,268 since inception and had not yet generated any revenue from operations. Additionally, management anticipates that its cash on hand as of December 31, 2025, combined with capital raised subsequent to December 31, 2025, is sufficient to fund its planned operations within one year after the date that the financial statements are issued.

Previous wording

To date, we have devoted most of our financial resources to corporate overhead, preparing for and conducting the clinical trial and marketing of our securities. We have not generated any revenues from product sales. We expect to continue to incur losses for the foreseeable future, and we expect these losses to increase as we continue our development of and seek regulatory approvals for Berubicin and TPI 287, prepare for and begin the commercialization of any approved products, and add infrastructure and personnel to support our continuing product development efforts. We anticipate that any such losses could be significant for the next several years. If Berubicin or any of our other drug candidates fail in clinical trials or do not gain regulatory approval, or if our drug candidates do not achieve market acceptance, we may never become profitable. As a result of the foregoing, we expect to continue to experience net losses and negative cash flows for the foreseeable future. These net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

Previous wording

We are a clinical pharmaceutical company with limited operating history. Our operations to date have been limited to acquiring our technology portfolio, preparing for and conducting our Berubicin clinical trial, and preparing for and conducting our TPI 287 clinical trial. We have not yet obtained any regulatory approvals for any of our drug candidates. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a longer operating history or approved products on the market. Our operating results are expected to significantly fluctuate from quarter to quarter or year to year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include:

Previous wording

We cannot be certain that TPI 287 and Berubicin will receive regulatory approval, and without regulatory approval we will not be able to market TPI 287 and Berubicin.

Current wording

We cannot be certain that any of our future product candidates will receive regulatory approval, and without regulatory approval we will not be able to market or commercialize them.

Previous wording

Our business currently depends largely on the successful development and commercialization of TPI 287 and Berubicin. Our ability to generate revenue related to product sales, if ever, will depend on the successful development and regulatory approval of TPI 287 and Berubicin for the treatment of glioblastoma.

Current wording

Our business strategy depends on identifying and in licensing the rights to new assets focused on neurology and oncology. There can be no assurances that we will be successful in executing on our strategy, which could have a material adverse impact on our business. Even if we are successful in securing rights to new assets, the development pathway to approval may be long, have uncertainty, and require more resources than we are able to obtain. Our ability to generate revenue related to product sales, if ever, will depend on the successful development and regulatory approval of any future product candidates.

Previous wording

If we are unable to obtain approval from the FDA, or other regulatory agencies, for Berubicin and our other product candidates, or if, subsequent to approval, we are unable to successfully commercialize Berubicin or our other product candidates, we will not be able to generate sufficient revenue to become profitable or to continue our operations, likely resulting in the total loss of principal for our investors.

Current wording

If we are unable to obtain approval from the FDA, or other regulatory agencies, for our product candidates, or if, subsequent to approval, we are unable to successfully commercialize our product candidates or secure commercialization partners, we will not be able to generate sufficient revenue to become profitable or to continue our operations, likely resulting in the total loss of principal for our investors.

Previous wording

Any statements in this filing indicating that TPI 287 and Berubicin has demonstrated preliminary evidence of efficacy are our own and are not based on the FDA’s or any other comparable governmental agency’s assessment of TPI 287 and Berubicin and do not indicate that TPI 287 and Berubicin will achieve favorable efficacy results in any later stage trials or that the FDA or any comparable agency will ultimately determine that TPI 287 and Berubicin is effective for purposes of granting marketing approval.

Current wording

Any statements in this filing indicating that our legacy assets TPI 287 and Berubicin have demonstrated preliminary evidence of efficacy are our own and are not based on the FDA’s or any other comparable governmental agency’s assessment of TPI 287 and Berubicin and do not indicate that TPI 287 and Berubicin will achieve favorable efficacy results in any later stage trials or that the FDA or any comparable agency will ultimately determine that TPI 287 and Berubicin is effective for purposes of granting marketing approval. Based on our intention to explore out-licensing TPI 287 and Berubicin, we may have limited or no ability to determine the future development or regulatory activity for these programs.

Previous wording

Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for TPI 287 and Berubicin and our other product candidates.

Current wording

Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for our product candidates.

Previous wording

If TPI 287 and Berubicin is found to be unsafe or lack efficacy, we will not be able to obtain regulatory approval for it and our business would be materially and possibly irreparably harmed.

Current wording

If a future product candidate is found to be unsafe or ineffective, we will not be able to obtain regulatory approval for it and our business would be materially and possibly irreparably harmed.

Previous wording

In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in composition of the patient populations, adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. We do not know whether any clinical trials we or any of our potential future collaborators may conduct will demonstrate the consistent or adequate efficacy and safety that would be required to obtain regulatory approval and market any products. If we are unable to bring Berubicin to market, or to acquire other products that are on the market or can be developed, our ability to create long-term stockholder value will be limited.

Previous wording

Unforeseen side effects from any of our product candidates could arise either during clinical development or, if TPI 287 and Berubicin (or our other product candidates) are approved, after the approved product has been marketed. The range and potential severity of possible side effects from therapies such as TPI 287 and Berubicin (or our other product candidates) are significant. If TPI 287 and Berubicin (or our other product candidates) causes undesirable or unacceptable side effects in the future, this could interrupt, delay or halt clinical trials and result in the failure to obtain or suspension or termination of marketing approval from the FDA and other regulatory authorities, or result in marketing approval from the FDA and other regulatory authorities only with restrictive label warnings.

Previous wording

We do not have any manufacturing capabilities and we do not intend to manufacture the pharmaceutical products that we plan to sell. We utilize contract manufacturers for the production of the active pharmaceutical ingredients and the formulation of drug product for our pre-clinical development and clinical trials of TPI 287 and Berubicin that we will need to conduct prior to seeking regulatory approval. However, we do not have agreements for supplies of TPI 287 and Berubicin or any of our other product candidates and we may not be able to reach agreements with these or other contract manufacturers for sufficient supplies to commercialize TPI 287 or Berubicin if they are approved. Additionally, the facilities used by any contract manufacturer to manufacture Berubicin or any of our other product candidates must be the subject of a satisfactory inspection before the FDA approves the product candidate manufactured at that facility. We will be completely dependent on these third-party manufacturers for compliance with the requirements of U.S. and non-U.S. regulators for the manufacture of our finished products. If our manufacturers cannot successfully manufacture material that conform to our specifications and the FDA’s current good manufacturing practice standards, or GMP, and other requirements of any governmental agency whose jurisdiction to which we are subject, our product candidates will not be approved or, if already approved, may be subject to recalls. Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured our product candidates, including:

Previous wording

We have no sales, marketing, or distribution experience. To develop sales, distribution, and marketing capabilities, we will have to invest significant amounts of financial and management resources, some of which will need to be committed prior to any confirmation that Berubicin or any of our other product candidates will be approved by the FDA. For product candidates where we decide to perform sales, marketing, and distribution functions ourselves or through third parties, we could face a number of additional risks, including that we or our third-party sales collaborators may not be able to build and maintain an effective marketing or sales force. If we use third parties to market and sell our products, we may have limited or no control over their sales, marketing and distribution activities on which our future revenues may depend.

Previous wording

Our licensed U.S. patents for Berubicn expired in March 2020 and the patents for TPI 287 will expire before commercialization is reasonably possible, and the expiration of our patents may subject us to increased competition, and the Orphan Drug Designations for TPI 287 and Berubicin will not bar approval of other similar products under certain circumstances.

Current wording

Our licensed U.S. patents for Berubicin have expired and our licensed U.S. patents for TPI 287 will expire before commercialization is reasonably possible, and the expiration of our patents may subject us to increased competition, and the Orphan Drug Designations for TPI 287 and Berubicin will not bar approval of other similar products under certain circumstances.

Previous wording

The U.S. and foreign patents for TPI 287 will all expire in 2028 well before commercialization is reasonably possible. The U.S. patents for Berubicin that we previously licensed from Houston Pharmaceuticals, Inc. expired in March 2020. Such patent expirations may subject us to increased competition. TPI 287 held Orphan Drug Designation when we licensed it from Cortice and on June 10, 2020, the FDA granted Orphan Drug Designation for Berubicin for the treatment of malignant gliomas. ODD from the FDA is available for drugs targeting diseases with less than 200,000 cases per year. ODD may enable market exclusivity of 7 years from the date of approval of an NDA in the United States. During that period the FDA generally could not approve another product containing the same drug for the same designated indication. Orphan drug exclusivity will not bar approval of another product under certain circumstances, including if a subsequent product with the same active ingredient for the same indication is shown to be clinically superior to the approved product on the basis of greater efficacy or safety, or providing a major contribution to patient care, or if the company with orphan drug exclusivity is not able to meet market demand. The ODD now constitutes our primary intellectual property protections although we are exploring if there are other patents that could be filed related to Berubicin to extend additional protections. The ODD similarly strengthens our TPI 287 patent protections and would become our primary protection upon expiration of those patents, however, we are also exploring new patent opportunities related to TPI 287. Nevertheless, we can provide no assurance that we will be able to file or receive additional patent protection. The failure to obtain additional patent protection will reduce the barrier to entry for competition for TPI 287 or Berubicin, which may adversely affect our operations.

Previous wording

As of March 31, 2025, we have four full-time employees. We also have 1 officer serving as part-time employee. As we advance our product candidates through preclinical studies and clinical trials, we will need to increase our product development, scientific and administrative headcount to manage these programs. In addition, to meet our obligations as a public company, we may need to increase our general and administrative capabilities. Our management, personnel, and systems currently in place may not be adequate to support this future growth. If we are unable to successfully manage this growth and increased complexity of operations, our business may be adversely affected.

Current wording

As of March 31, 2026, we have eight full-time employees. As we secure rights to and advance product candidates through preclinical studies and clinical trials, we will need to increase our product development, scientific and administrative headcount to manage these programs. In addition, to meet our obligations as a public company, we may need to increase our general and administrative capabilities. Our management, personnel, and systems currently in place may not be adequate to support this future growth.

Previous wording

We are dependent on John M. Climaco, Christopher Downs, Sandra Silberman, and Donald Picker in order to conduct our operations and execute our business plan, however, we have not purchased any insurance policies with respect to those individuals in the event of their death or disability. Therefore, if any of John M. Climaco, Christopher Downs, Sandra Silberman, or Donald Picker die or become disabled, we will not receive any compensation to assist with such person’s absence. The loss of such person could negatively affect us and our operations.

Current wording

We are dependent on our executive leadership team: Rami Levin, Eric Faulkner, Lynne Kelley, Steve O’Loughlin and Dylan Wenke in order to conduct our operations and execute our business plan, however, we have not purchased any insurance policies with respect to those individuals in the event of their death or disability. Therefore, if any of our current executives die or become disabled, we will not receive any compensation to assist with such person’s absence. The loss of such person could negatively affect us and our operations.

Previous wording

There are limited suppliers for active pharmaceutical ingredients (“API”) used in our drug candidates. Problems with the third parties that manufacture the API used in our drug candidates, or in the supply chain between the manufacturer and CNS, may delay our clinical trials or subject us to liability.

Events involving limitations to liquidity, defaults, non-performance or other adverse developments that affect financial institutions, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, the FDIC, took control and was appointed receiver of Silicon Valley Bank (to which the Company had no exposure). If other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash, cash equivalents and investments may be threatened and could have a material adverse effect on our business and financial condition.

Current wording

We regularly maintain cash balances at third-party financial institutions. Our cash investment strategy is intended to preserve capital and minimize cash balances that exceed the Federal Deposit Insurance Corporation, or FDIC, insurance limit. However, our cash balances may exceed the FDIC insurance limit from time to time. Events involving limitations to liquidity, defaults, non-performance or other adverse developments that affect financial institutions, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, the FDIC, took control and was appointed receiver of Silicon Valley Bank (to which the Company had no exposure). If other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash, cash equivalents and investments may be threatened and could have a material adverse effect on our business and financial condition.

Management performed an annual assessment as of December 31, 2024 of the effectiveness of our internal control over financial reporting for its annual report. Our management concluded that our internal control over financial reporting was, and continues to be, ineffective as of December 31, 2024, due to material weaknesses in our internal controls due to the lack of segregation of duties (resulting from the limited number of personnel available), limited access to timely and complete information regarding the status of costs incurred in the activation of investigational sites and costs from treating patients in our study which is a result of the use of a third-party Contract Research Organization (“CRO”) to manage the study, and the lack of formal documentation of our control environment. For as long as we remain an “emerging growth company” as defined in the JOBS Act, we have and intend to consider to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act. We may continue to take advantage of these reporting exemptions until we are no longer an “emerging growth company.” To mitigate the lack of segregation of duties material weaknesses, we engaged an outside firm to assist management with such accounting and will continue to use outside firms as a resource to deal with other non-recurring or unusual transactions. However, notwithstanding our mitigation efforts, there is no assurance we will not encounter accounting errors in the future. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, and investors could lose confidence in our reported financial information.

Current wording

Management performed an annual assessment as of December 31, 2025 of the effectiveness of our internal control over financial reporting for its annual report. Our management concluded that our internal control over financial reporting was, and continues to be, ineffective as of December 31, 2025, due to material weaknesses in our internal controls due to the lack of segregation of duties (resulting from the limited number of personnel available), limited access to timely and complete information regarding the status of costs incurred in the activation of investigational sites and costs from treating patients in our study which is a result of the use of a third-party Contract Research Organization (“CRO”) to manage the study, and the lack of formal documentation of our control environment. For as long as we remain a smaller reporting company as defined by Rule 12b-2 of the Exchange Act, we have and intend to consider to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not a smaller reporting company including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act. We may continue to take advantage of these reporting exemptions until we are no longer a smaller reporting company. To mitigate the lack of segregation of duties material weaknesses, we engaged an outside firm to assist management with such accounting and will continue to use outside firms as a resource to deal with other non-recurring or unusual transactions. To mitigate the lack of formal documentation of the control environment, we have key team members review the critical reports and reconciliations as well as reporting documents. To mitigate the limited access to timely and complete information regarding the status of costs incurred in the activation of investigational sites and costs from treating patients in the study which is a result of the use of a third-party Contract Research Organization (“CRO”) to manage the study, we have senior leaders of our finance and research teams review period end estimates. However, notwithstanding our mitigation efforts, there is no assurance we will not encounter accounting errors in the future. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, and investors could lose confidence in our reported financial information.

Previous wording

During 2024, we were not in compliance with the requirement to maintain a closing bid price of $1.00 per share (the “Minimum Bid Price Requirement”) pursuant to Nasdaq Listing Rule 5550(a)(2), and we were not in compliance with the minimum $2,500,000 stockholders’ equity requirement for continued listing set forth in Listing Rule 5550(b) (the “Equity Requirement”). As of the date of this filing, we are in compliance with both requirements. However, with respect to the Equity Requirement, pursuant to Nasdaq Listing Rule 5815(d)(4)(B), we are subject to a Mandatory Panel Monitor until September 10, 2025. If, within that monitoring period, the Staff finds us again out of compliance with the Equity Requirement, notwithstanding Listing Rule 5810(c)(2), we will not be permitted to provide the Staff with a plan of compliance with respect to that deficiency and Staff will not be permitted to grant additional time for us to regain compliance with respect to that deficiency, nor will we be afforded an applicable cure or compliance period pursuant to Listing Rule 5810(c)(3). With respect to the Minimum Bid Price Requirement, since we completed a reverse split on February 21, 2025, if we fall out of compliance with the Minimum Bid Price Requirement prior to February 21, 2026, we will not be eligible for any compliance period specified in Listing Rule 5810(c)(3)(A). In either case described in the preceding two sentences, the Staff will issue a Delist Determination Letter and we will have an opportunity to request a hearing. Our common stock may be at that time be delisted from Nasdaq.

Current wording

During 2024, we experienced compliance deficiencies with respect to the requirement to maintain a closing bid price of $1.00 per share (the “Minimum Bid Price Requirement”) pursuant to Nasdaq Listing Rule 5550(a)(2), and the minimum $2,500,000 stockholders’ equity requirement for continued listing set forth in Listing Rule 5550(b) (the “Equity Requirement”). We have since remedied these deficiencies and, as of the date of this filing, we are in compliance with all applicable Nasdaq listing requirements.

Previous wording

There can be no assurance that we will continue to meet the continued listing requirements of The Nasdaq Capital Market and could be subject to delisting at a future time. Delisting from The Nasdaq Capital Market would adversely affect our ability to raise additional financing through the public or private sale of equity securities, may significantly affect the ability of investors to trade our securities and may negatively affect the value and liquidity of our common stock. Delisting also could have other negative results, including the potential loss of employee confidence, the loss of institutional investors or interest in business development opportunities.
