New heading “Risks Relating to Investing in Digital Securities”

New heading “The launch of central bank digital currencies (“CBDCs”) may adversely impact our business.”

New heading “Absent federal regulations, there is a possibility that any digital asset we acquire may be classified as a “security.” Any classification of any digital asset we acquire as a “security” would subject us to additional regulation and could materially impact the operation of our business.”

New heading “If we were deemed to be an investment company under the 1940 Act, applicable restrictions likely would make it impractical for us to continue segments of our business as currently contemplated.”

New heading “We may be subject to regulatory developments related to crypto assets and crypto asset markets, which could adversely affect our business, financial condition, and results of operations.”

New heading “Cryptocurrency assets are less liquid than our existing cash and cash equivalents and may not be able to serve as a source of liquidity for us to the same extent as cash and cash equivalents.”

New heading “We are not subject to legal and regulatory obligations that apply to investment companies such as mutual funds and exchange-traded funds, or to obligations applicable to investment advisers.”

New heading “If we or our third-party service providers experience a security breach or cyberattack and unauthorized parties obtain access to any of our acquired digital assets, or if our private keys are lost or destroyed, or other similar circumstances or events occur, we may lose some or all of our digital assets and our financial condition and results of operations could be materially adversely affected.”

Removed

We have incurred losses since our inception and anticipate that we will continue to incur increasing losses for the foreseeable future.

Removed

Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing.

Removed

We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to complete the development and commercialization of THIO.

Removed

Raising additional capital may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our product candidates on unfavorable terms to us.

Removed

We have a limited operating history and no history of commercializing pharmaceutical products, which may make it difficult to evaluate the prospects for our future viability.

Removed

We are heavily dependent on the success of THIO, our most advanced candidate, which is still under clinical development, and if this drug does not receive regulatory approval or is not successfully commercialized, our business may be harmed.

Removed

Clinical trials are expensive, time consuming, difficult to design and implement, and involve uncertain outcomes.

Removed

Our product candidates are based on novel technologies, which make it difficult to predict the timing, results and cost of product candidate development and likelihood of obtaining regulatory approval.

Removed

We may find it difficult to enroll patients in our clinical trials given the limited number of patients who have the diseases for which our product candidates are being studied which could delay or prevent the start of clinical trials for our product candidates.

Removed

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Removed

The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming, expensive, and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for THIO or any other candidates, our business will be substantially harmed.

Removed

Enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be made more difficult or rendered impossible by multiple factors outside our control.

Removed

Results of preclinical studies, early clinical trials or analyses may not be indicative of results obtained in later trials.

Removed

The market opportunities for THIO, if approved, may be smaller than we anticipate.

Removed

Development of THIO could take longer, be more expensive, or become impractical if the FDA requires the use of an FDA-approved companion diagnostic test in conjunction with treatment with THIO.

Removed

If we are unable to obtain FDA approval for our IND application for the planned THIO Phase 2 trial, our clinical development of THIO may be significantly delayed and our business may be substantially harmed.

Removed

Even if we obtain FDA approval for THIO or any other candidates in the United States, we may never obtain approval for or commercialize THIO or any other development candidate in any other jurisdiction, which would limit our ability to realize their full global market potential.

Removed

The successful commercialization of THIO and any other candidate we develop will depend in part on the extent to which governmental authorities and health insurers establish adequate coverage, reimbursement levels, and pricing policies.

Removed

Even if THIO or any candidate we develop receives marketing approval, it may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community necessary for commercial success.

Removed

If we are unable to establish sales, marketing and distribution capabilities either on our own or in collaboration with third parties, we may not be successful in commercializing THIO, if approved.

Removed

A variety of risks associated with operating internationally could materially adversely affect our business.

Removed

Our employees and independent contractors, including principal investigators, clinical trial sites, contract research organizations (“CROs”), consultants, vendors, and any third parties we may engage in connection with development and commercialization, may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our business.

Removed

We currently rely on third-party contract manufacturing organizations, or CMOs, for the production of clinical supply of THIO and intend to rely on CMOs for the production of commercial supply of THIO, if approved. Our dependence on CMOs may impair the development and commercialization of the drug, which would adversely impact our business and financial position.

Removed

We intend to rely on third parties to conduct, supervise and monitor our clinical trials. If those third parties do not successfully carry out their contractual duties, or if they perform in an unsatisfactory manner, it may harm our business.

Removed

We depend on license agreements with the University of Texas Southwestern, or UTSW, to permit us to use patents and patent applications, as well as to exploit specific technological know-how. Termination of these rights or the failure to comply with obligations under these agreements could materially harm our business and prevent us from developing or commercializing our product candidates.

Removed

We have been granted licenses of use to patent applications. There can be no assurance that any of the patent applications that we have licenses to will result in issued patents. As a result, our ability to protect our proprietary technology in the marketplace may be limited.

Removed

Our patents may be challenged in courts or in patent offices which could result in the invalidation, narrowing or unenforceability of our patents and our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Removed

Changes in patent laws or patent jurisprudence could diminish the value of patents in general, thereby impairing our ability to protect our product candidates.

Removed

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Removed

Intellectual property rights do not address all potential threats to our competitive advantage.

Removed

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that our trade secrets will be misappropriated or disclosed, and confidentiality agreements with employees and third parties may not adequately prevent disclosure of trade secrets and protect other proprietary information.

Removed

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Removed

We may need to license certain intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms.

Removed

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of their former employers or other third parties.

Removed

We expect to expand our development, regulatory, and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

Removed

The price of our common stock may be volatile and you could lose all or part of your investment.

Removed

We do not intend to pay dividends for the foreseeable future, and our ability to pay dividends to our stockholders is restricted by applicable laws and regulations.

Removed

We may, in the future, issue additional capital stock, which would reduce investors’ percent of ownership and may dilute our share value.

Removed

Our failure to meet the continued listing requirements of NYSE American could result in a delisting of our common stock.

Removed

Our failure to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business, financial condition, and results of operations.

Removed

The limited public company experience of our management team could adversely impact our ability to comply with the reporting requirements of U.S. securities laws, which could have a materially adverse effect on our business.

Removed

Our shares of common stock are currently listed on NYSE American. If we are unable to maintain listing of our securities on NYSE American or any stock exchange, our stock price could be adversely affected and the liquidity of our stock and our ability to obtain financing could be impaired and it may be more difficult for our stockholders to sell their securities.

Reworded

We expect to incur significant additional operating losses for the next several years, at least, as we advance THIOateganosine and any other candidates through clinical development, complete clinical trials, seek regulatory approval and commercialize the drug or any other candidates, if approved. The costs of advancing candidates into each clinical phase tend to increase substantially over the duration of the clinical development process. Therefore, the total costs to advance any of our candidates to marketing approval in even a single jurisdiction will be substantial. Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to begin generating revenue from the commercialization of any products or achieve or maintain profitability. Our expenses will also increase substantially if and as we:

Removed

conduct clinical trials for any other indications or other candidates;

Removed

establish sales, marketing, distribution, and compliance infrastructures to commercialize our drug, if approved, and for any other candidates for which we may obtain marketing approval;

Removed

maintain, expand and protect our intellectual property portfolio;

Removed

hire additional clinical, scientific and commercial personnel;

Removed

add operational, financial and management information systems and personnel, including personnel to support our development and planned future commercialization efforts, as well as to support our transition to a public reporting company; and acquire or in-license or invent other candidates or technologies.

Removed

Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing.

Removed

Our financial statements as of December 31, 2024 have been prepared under the assumption that we will continue as a going concern for the next twelve months. Our independent registered public accounting firm included in its opinion for the year ended December 31, 2024 an explanatory paragraph referring to our recurring losses, negative cash flow from operations and has accumulated a deficit of $87,234,833 from the Company’s inception through December 31, 2024 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 create new business opportunities and eventually attain profitable operations. Our financial statements as of December 31, 2024 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 by our auditors, 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.

Reworded

We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to complete the development and commercialization of THIO.ateganosine.

Reworded

Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts to advance the clinical development of THIOateganosine and launch and commercialize THIO,ateganosine, if we receive regulatory approval. We will require additional capital for the further development and potential commercialization of THIOateganosine and may also need to raise additional funds sooner to pursue a more accelerated development of THIO.ateganosine. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts. efforts.Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to the:

Removed

Based on our cash reserves at December 31, 2024 of $9.60 million and current financial condition as of the date of this Annual Report on Form 10-K, there is substantial doubt about our ability to continue as a going concern. (See — Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Capital Resources — Our Ability to Continue as a Going Concern” for further information.) Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to the:

Removed

initiation, progress, timing, costs and results of preclinical studies and clinical trials, including patient enrollment in such trials, for THIO or any other future candidates;

Removed

clinical development plans we establish for THIO and any other future candidates;

Removed

obligation to make royalty and non-royalty sublicense receipt payments to third-party licensors, if any, under our licensing agreements;

Removed

number and characteristics of candidates that we discover or in-license and develop;

Removed

outcome, timing and cost of regulatory review by the FDA and comparable foreign regulatory authorities, including the potential for the FDA or comparable foreign regulatory authorities to require that we perform more studies than those that we currently expect;

Removed

costs of filing, prosecuting, defending and enforcing any patent claims and maintaining and enforcing other intellectual property rights;

Removed

effects of competing technological and market developments;

We are a clinical stage biotechnology company engaged in the discovery, development and commercialization of therapies targeting cancer. Our initial disease target is lung cancer, a serious medical condition with an incidence of over 236,000 new cases in the US in 2022, representing 12.3% of all cancers, and over 130,000 deaths, or 21.4% of all cancers. Worldwide, lung cancer incidence is over 2,200,000 per year (ranking second only after breast cancer), and mortality over 1,800,000 (ranking first). Specifically, we are targeting Non-Small Cell Lung Cancer (“NSCLC”), which represents 85% of all lung cancers. THIOAteganosine (THIO, 6-thio-dG or 6-thio-2 ‘-deoxyguanosine), our lead asset, is an investigational dual mechanism of action drug candidate incorporating telomere targeting and immunogenicity.

We are a clinical-stage biopharmaceutical company developing targeted immunotherapies for cancer. THIOAteganosine (THIO, 6-thio-dG or 6-thio-2 ‘-deoxyguanosine), our lead asset, is an investigational dual mechanism of action drug candidate incorporating telomere targeting and immunogenicity. In July 2022, the first patient was administered with THIOateganosine in our Phase 2 human trial (THIO-101) in Australia. In December 2022, regulatory authorities in three European countries, Hungary, Poland, and Bulgaria, approved the implementation of THIO-101, Phase 2 clinical trial evaluating THIOateganosine in patients with Non-Small Cell Lung Cancer (NSCLC). PatientsIn the trial, patients with advanced NSCLC will beare treated first with THIOateganosine followed a few days later by the immune checkpoint inhibitor Libtayo® (cemiplimab), manufactured and commercialized by Regeneron. Cemiplimab is a fully human monoclonal antibody targeting the immune checkpoint receptor PD-1 on T-cells. Cemiplimab has been approved in the United States and the rest of the world for multiple cancer indications, including NSCLC. In February 2021, we signed a clinical supply agreement with Regeneron to receive cemiplimab at no cost, which represents a significant cost-savings for the study. In return, we have granted Regeneron exclusive development rights in combination with PD-1 inhibitors for NSCLC for the study period. In July 2025, we initiated an expansion of the THIO-101 trial focused on third-line NSCLC patients who are resistant to checkpoint inhibitors and chemotherapy. The expansion will enroll up to 48 patients with two arms: Arm 1, continuing the evaluation of ateganosine sequenced with Libtayo® (cemiplimab); and Arm 2, evaluating ateganosine as a monotherapy, to further gain experience of ateganosine in the contribution of components. Based on the clinical data generated by our THIO-101 trial, we plan to seek filing for an accelerated approval of THIOateganosine in the United States for the treatment of patients with advanced NSCLC in 2026, but even if granted, accelerated approval status does not guarantee an accelerated review or marketing approval by the Food and Drug Administration (FDA)..We We plan to initiateinitiated a Phase 3 pivotal trial in 2025, named THIO-104, to evaluate the efficacy of THIOateganosine administered in sequence with a checkpoint inhibitor (CPI) in third-line non-small cell lung cancer (NSCLC) patients who are resistant to checkpoint inhibitors and chemotherapy which could lead filing for early full commercial approval in 2026 and final analysis could lead to filing for full commercial approval in 2027.chemotherapy. The multicenter, open-label, pivotal Phase 3 trial is designed to provide a direct comparison to chemotherapy in a 1:1 randomization of up to 300 patients. In addition, the originally planned Phase 2 clinical trial in multiple tumor indications (THIO-102) is now divided into different trials for one tumor indication each: hepatocellular carcinoma (HCC), colorectal cancer (CRC) and small cell lung cancer (SCLC). Phase 2 clinical trials in HCC, CRC and SCLC are planned to be initiated in 2026, evaluating treatment with THIOateganosine administered in sequence with BeiGene's BeOne’s immune checkpoint inhibitor, tislelizumab. Clinical trials with other solid tumors (ST), such as breast, prostate, gastric, pancreatic and ovarian, may still be considered for potential future trials.

On January 17, 2024, we announced new interim data for our ongoing THIO-101 Phase 2 trial in non-small cell lung cancer (NSCLC). In the latest available data from THIO-101 (November 13, 2023), 60 patients had been dosed with THIO in sequential combination with Libtayo®. The patients received either 60mg, 180mg, or 360mg of THIO per dose, and 42 had at least one post baseline assessment completed. The observed disease control was well sustained compared to previous scans.

Removed

On February 7, 2024, we announced publication of international Patent Cooperation Treaty (“PCT”) application titled “Dinucleotides and Their Use in Treating Cancer.” The new dinucleotides disclosed in the patent application are telomere-targeting molecules, such as THIO fragments or other THIO analogues. These compounds are key next-generation telomere-targeting agents, an important extension of MAIA’s innovative cancer treatment platform. The PCT system streamlines the process for obtaining patent protection globally. Under the PCT, applicants can seek patent protection in a large number of countries.

On February 14, 2024, we entered into an At The Market Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC (“Wainwright”), to sell shares of our Common Stock having an aggregate sales price of up to $1,445,000, from time to time, through an “at-the-market offering” program under which Wainwright will act as sales agent. Effective March 25, 2024, the Company filed a prospectus supplement to amend, supplement and supersede certain information contained in the earlier prospectus and prospectus supplement, which increased the number of shares of Common Stock the Company may offer and sell under the ATM Agreement to an aggregate offering price of up to $4,950,000 from time to time. Effective May 15, 2024, the Company filed a prospectus supplement to amend, supplement and supersede certain information contained in the earlier prospectus and prospectus supplement, which increased the number of Shares the Company may offer and sell under the ATM Agreement to an aggregate offering price of up to $11,280,000 from time to time. Effective December 23, 2024, the Company filed a prospectus supplement to amend, supplement and supersede certain information contained in the earlier prospectus and prospectus supplement, which increased the number of Shares the Company may offer and sell under the ATM Agreement to an aggregate offering price of up to $30,000,000 from time to time. As of the date of this Annual Report, we have sold 3,940,683 shares of our Common Stock under the ATM Agreement at an average price of $2.95 per share, resulting in aggregate gross proceeds of approximately $11,633,086, for which we paid Wainwright $348,993 in commissions resulting in net proceeds to us of approximately $11,284,093.

On February 22, 2024, we announced completion of enrollment in Phase 2 THIO-101 go-to-market clinical trial. The trial reached the enrollment target of 41 patients for the 180mg/dose on February 19, 2024. As of the latest data available for the trial, 79 patients had received either 60mg (24 patients), 180mg (41 patients) or 360mg (14 patients). The original trial design targeted up to 182 patients, including all patients in the safety lead-in and 41 patients in each of the 3 tested doses (60mg, 180mg, and 360mg). Following the selection of 180 mg/cycle as the optimal dose in December 2023, all patients were subsequently enrolled at the 180mg/cycle dose and trial enrollment was completed ahead of schedule.

The company chose a name inspired by the mechanism of action of THIO: altering telomeric guanosine of the cancer cells. The generic name ateganosine is a unique and consistent identity that aims to support clear communication between healthcare providers, patients and researchers. MAIA will retain the name THIO in its clinical trial designations (THIO-101, THIO-102, THIO-103, THIO-104).

On March 20, 2025, we announced the publication of preclinical data for its lead proprietary telomere-targeting THIO dimer in the peer-reviewed scientific journal Naunyn-Schmiedeberg's Archives of Pharmacology. In a preclinical study, THIO and its new described dimer form were found to be potent inhibitors of Glutathione S-transferase Pi (GSTP1), a key enzyme implicated in cancer progression and chemoresistance and a highly important factor for the detoxification of cancer cells. The findings suggest that the dimerized form of THIO could enhance chemotherapeutic efficacy by effectively targeting GSTP1 and reducing drug resistance. The article, titled “Investigation of the inhibitory effects of the telomere-targeted compounds on glutathione S-transferase P1,” was published on February 15, 2025.

Our Ability to Continue as a Going Concern

Removed

As of December 31, 2024, our available cash totaled approximately $9,601,000 which represented an increase of approximately $2,451,000 compared to December 31, 2023. As of December 31, 2024, we had working capital of approximately $6,322,000 which represents an increase of approximately $3,696,000 compared to December 31, 2023. We have generated no revenues as of December 31, 2024. The Company’s current operating plan indicates that it will continue to incur losses from operations and generate negative cash flows from operating activities given ongoing expenditures related to the completion of its ongoing clinical trials and the Company’s lack of revenue generating activities. Based on the Company’s cash reserves as December 31, 2024 of $9,601,298 and current financial condition as of the date of the Annual Report on Form 10-K, the accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Removed

To meet the Company’s future working capital needs, the Company will need to raise additional equity or enter into debt financing. While the Company has historically been able to raise additional capital through issuance of equity and/or debt financing, and while the Company has implemented a plan to control its expenses in order to satisfy its obligations due within one year from the date of issuance of these financial statements, the Company cannot guarantee that it will be able to raise additional equity, raise debt, or contain expenses. Accordingly, there is substantial doubt about the Company’s ability to continue as a going concern within one year after these financial statements are issued.
