Current report
our ability to offer our products for sale at competitive prices and the availability of third-party coverage and adequate reimbursement;
Current report
Likewise, statements made by investigators, patients, or others participating in our clinical trials as to the effect or effects of therapy they may have observed, should not be relied upon as applicable generally to all patients with the disease, or all or most patients participating in the trials. Statements made on social media or in scientific discussions of an ongoing clinical trial should not be reviewed as company statements. Such observations, made by an individual who by design is unaware of a patient’s treatment assignment, or who is observing a patient’s reaction outside the setting of controlled study, e.g. in an open-label setting, may not be reliable as predictors of a population’s response. Such statements, while factual, should not be understood to be predictive of a larger population’s eventual response to the therapy once study data from all participants is analyzed.
Current report
our ability to establish or maintain collaborations, licensing or other arrangements and risks related thereto;
Current report
at any time, review division staff and senior leadership within FDA and other regulatory agencies may reverse their policy or change the application of a policy to a given drug development program, resulting in faster or slower than expected approval, and this internal discussion may be time consuming and effect the Company’s approach to study or applying for approval of a product;

Our business, financial condition and operating results may be affected by a number of factors, including but not limited to those described below. Any one or more of such factors could directly or indirectly cause our actual results of operations and financial condition to vary materially from our past or anticipated future results of operations and financial condition. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, results of operations and stock price. The following information should be read in conjunction with Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the accompanying financial statements and related notes in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K.

Previous wording
At present we are focusing our resources on developing levosimendan for the treatment of PH-HFpEF, while imatinib for the treatment of PAH remains part of our portfolio. We intend to commit most of our resources to advancing levosimendan to the point it receives regulatory approval for the treatment of pulmonary hypertension in patients with HFpEF. Depending on whether we raise additional funds in the future, as well as on decisions made by the USPTO, clinical trial results and other information revealed by competitors, and other factors, we will prioritize our funding and other resources. If as a consequence of the results of our planned Phase 3 trials for levosimendan, or the results of prior clinical trials performed using levosimendan or imatinib, we are unable to receive regulatory approval of one or both of our existing product candidates, then we may not have resources to pursue development of any other products and our business could terminate.

Previous wording
The process of developing new drugs and/or therapeutic products is inherently complex, unpredictable, time-consuming, expensive and uncertain. We must make long-term investments and commit significant resources before knowing whether our development programs will result in products that will receive regulatory approval and achieve market acceptance. Product candidates that appear to be promising at some or all stages of development may not receive approval or reach the market for a number of reasons that may not be predictable based on results and data of the clinical program. Product candidates may be found ineffective or may cause harmful side effects during clinical trials, may take longer to progress through clinical trials than had been anticipated, may not be able to achieve the pre-defined clinical endpoints due to statistical anomalies even though clinical benefit may have been achieved, may fail to receive necessary regulatory approvals, may prove impracticable to manufacture in commercial quantities at reasonable cost and with acceptable quality, or may fail to achieve market acceptance. Even if we believe the preclinical or clinical data for our product candidates are favorable, such data may not be sufficient to support approval by the FDA and other regulatory authorities. Additionally, the FDA may require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or post-approval, or it may object to elements of our clinical development program.

Previous wording
Delays in the commencement, enrollment and completion of clinical testing could significantly affect our ability to gain FDA approval of current product candidates, and to gain this approval in the timeline planned, and could significantly increase our future product development costs. The completion of clinical trials requires us to identify and maintain a sufficient number of trial sites, many of which might already be engaged in other clinical trial programs for the same indication as our product candidates, might be required to withdraw from our clinical trial as a result of changing standards of care, might suffer from staff shortages at the institutional or clinic level that impact their ability to enroll and treat patients under our protocols, or might become ineligible to participate in clinical studies. The enrollment and completion of clinical trials can be delayed for a variety of other reasons, including delays related to:

We are required to conduct additional clinical trials, including the LEVEL and LEVEL-2 trials for oral levosimendan, which are expensive and time consuming, and the outcome of the clinical trials is uncertain.
Current wording
We are conducting two Phase 3 clinical trials, LEVEL and LEVEL-2 for oral levosimendan, which are expensive and time consuming, and the outcome of the clinical trials is uncertain.
Previous wording
We expect to commit a substantial portion of our financial and business resources in the short-term to completing the LEVEL and LEVEL-2 trials and advancing this product through to regulatory approval for use in PH-HFpEF, and potentially other indications. We may in the future commit resources to clinical trials for our other product candidates, including imatinib. All of these clinical trials and product testing efforts will be expensive and time consuming and the timing of the regulatory review process is uncertain. The applicable regulatory agencies may suspend clinical trials at any time if they believe that the subjects participating in such trials are being exposed to unacceptable health risks. We cannot assure you that we will be able to complete our clinical trials successfully or obtain FDA or other governmental or regulatory approval of our product candidates, or that such approval, if obtained, will not include limitations on the indicated uses for which our product candidates may be marketed. Our business, financial condition and results of operations are critically dependent on obtaining capital to advance our testing program and receiving FDA and other governmental and regulatory approvals of our products. A significant delay in or failure of our planned clinical trials or a failure to achieve these approvals would have a material adverse effect on us and could result in major business and financial setbacks.

Previous wording
From time to time, we may publish or reference interim, top-line, or preliminary results from our clinical trials, including of blinded or unblinded data. Interim or top-line results from clinical trials that we may complete are subject to the risk that one or more of the clinical outcome measurements may materially change as patient enrollment and treatment extends and more patient experience is observed. Preliminary or top-line results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final and complete data are available. Differences between preliminary or interim data and final data could significantly harm our business prospects and may cause the trading price of our common stock to fluctuate significantly.

We will require substantial additional funding to further develop our product candidates, including to complete the open label extension stage of our ongoing Phase 3 LEVEL trial and to complete a second planned global Phase 3 study, Level-2, as well as to initiate or complete an imatinib Phase 3 trial. Failure to obtain this necessary capital when needed on acceptable terms, or at all, or execute on an alternative strategic path, could force us to delay, limit, reduce or terminate our clinical trials, product development efforts and business operations.
Current wording
We will require substantial additional funding to further develop, file marketing authorization applications, and if approved, commercialize our product candidates, including to complete the open label extension stage of our ongoing Phase 3 LEVEL and LEVEL-2 trials of levosimendan; as well as to initiate or complete any future imatinib Phase 3 trial. Failure to obtain this necessary capital when needed on acceptable terms, or at all, or execute on an alternative strategic path, could force us to delay, limit, reduce or terminate our clinical trials, product development efforts and business operations.

As of December 31, 2024, we had $94.9 million of cash and cash equivalents on hand and subsequent to year end, on March 5, 2025 we raised an additional $25.0 million of gross proceeds from an offering of common stock and pre-funded warrants. We will need substantial additional capital in order to develop our product candidates, including to complete the LEVEL and LEVEL-2 trials, to complete the regulatory approval process and commercialization of levosimendan, and, potentially, imatinib, or any future product candidates. We continue to evaluate pursuing additional public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. Such funding may not be available on favorable terms, if at all.

We have incurred losses since inception. For the years ended December 31, 2024 and 2023, we incurred net operating losses of $19.5 million and $8.2 million, respectively. We have funded our operations since 2013 principally through the issuance of debt and equity securities. We will continue to incur losses until we generate sufficient revenue to offset our expenses, and we anticipate that we will continue to incur net losses for at least the next several years. We expect to incur additional expenses related to our development and potential commercialization of levosimendan for pulmonary hypertension and other potential indications, imatinib for PAH, as well as identifying and developing other potential product candidates, and as a result, we will need to generate significant net product sales, royalty and other revenues to achieve profitability.

Many of our current competitors have significant financial, marketing and personnel resources and development capabilities. For example, many large, well-capitalized companies already offer cardiovascular and pulmonary products and services in the United States and Europe that target the indications for which our product candidates are being developed, or related indications. Currently, as an example, at least twelve vasodilators are marketed in the U.S. for use in patients with PAH, and sales teams from Janssen, Pfizer, Bayer, United Therapeutics, and other large companies with marketing and sales capabilities represent these products in the specialized care centers where the disease is treated. While there are no products currently marketed to treat PH-HFpEF, specifically, some products are under development to treat this prevalent disease, and some products marketed for other conditions or for HFpEF alone, are used in these patients and could constitute competition at the patient, payor, or overall market level in future.

Current wording
Our activities are and will continue to be subject to extensive government regulation, which is difficult to predict, expensive and time-consuming, and we will not be able to sell our products without regulatory approval.
Previous wording
The FDA and other regulatory agencies continue to review products even after they receive agency approval. If and when the FDA or another regulatory agency outside the United States approves one of our products, its manufacture and marketing will be subject to ongoing regulation, which could include compliance with current good manufacturing practices, adverse event reporting requirements and general prohibitions against promoting products for unapproved or “off-label” uses. We are also subject to inspection and market surveillance by the FDA for compliance with these and other requirements. Any enforcement action resulting from failure, even by inadvertence, to comply with these requirements could affect the manufacture and marketing of levosimendan, imatinib or our other products. In addition, the FDA or other regulatory agencies could withdraw a previously approved product from the market upon receipt of newly discovered information. The FDA or another regulatory agency could also require us to conduct additional, and potentially expensive, studies in areas outside our approved indicated uses.

Previous wording
Obtaining an Orphan Drug Designation from the FDA may not effectively protect our product candidates from competition because different drugs can be approved for the same condition, and orphan drug exclusivity does not prevent the FDA from approving the same or a different drug in another indication. Even after an orphan drug is approved, the FDA can subsequently approve a later application for the same drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer in a substantial portion of the target populations, more effective, or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to manufacture sufficient quantities of the product to meet the needs of patients with the rare disease or condition. Orphan Drug Designation neither shortens the development time or regulatory review time of a drug nor gives the drug any advantage in the regulatory review or approval process.

Orphan Drug Designation neither shortens the development time nor regulatory review time of a drug and does not give the drug any advantage in the regulatory review or approval process. Furthermore, U.S. law and the application of law to the exclusivity of approved therapies for orphan diseases, has evolved, including with the Consolidated Appropriations Act of 2026, and this evolution may continue to evolve, impairing our ability to be assured of the same exclusivity and the resulting reimbursement for TNX-201 for its intended use.
Previous wording
Even after products are commercialized, we would expect to spend considerable time and money complying with federal and state laws and regulations governing their sale, and, if we are unable to fully comply with such laws and regulations, we could face substantial penalties.

The containment of healthcare costs is a priority of federal, state and foreign governments and the prices of drug products have been a focus in this effort. The continuing efforts of government, private insurance companies and other organizations to contain or reduce costs of healthcare, including through such recent legislation as the Inflation Reduction Act in the U.S., the effects of which are evolving over time, may adversely affect our ability to set as high a price for our products as we might otherwise and the rate and scope of adoption of our products by healthcare providers. We expect that federal, state and local governments in the United States, as well as governments in other countries, will continue to consider legislation directed at lowering the total cost of healthcare. In addition, in certain foreign markets, the pricing of drug products is subject to government control and reimbursement may in some cases be unavailable or insufficient. It is uncertain whether and how future legislation, whether domestic or abroad, could affect prospects for our product candidates or what actions governmental or private payers for healthcare treatment and services may take in response to any such healthcare reform proposals or legislation. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, may prevent or limit our ability to generate revenue, attain profitability or commercialize our product candidates.

We do not currently employ personnel or possess the facilities necessary to conduct many of the activities associated with our development programs. We have historically and we will continue to engage consultants, advisors, CROs and others to assist in the design and conduct of nonclinical and clinical studies of our product candidates, with interpretation of the results of those studies and with regulatory activities and expect to continue to outsource all or a significant amount of such activities. As a result, many important aspects of our development programs are and will continue to be outside our direct control and our third-party service providers may not perform their activities as required or expected, including the maintenance of Good Laboratory Practices (“GLP”) or Good Clinical Practices (“GCP”) compliance, which are ultimately our responsibility to ensure. Further, such third parties may not be as committed to the success of our programs as our own employees and, therefore, may not devote the same time, thoughtfulness, or creativity to completing projects or problem-solving as our own employees would. To the extent we are unable to successfully manage the performance of third-party service providers, our business may be adversely affected.

The CROs we engage or may engage to execute our clinical studies play a significant role in the conduct of the studies, including the collection and analysis of study data, and we likely will depend on CROs and clinical investigators to conduct future clinical studies and to assist in analyzing data from completed studies and developing regulatory strategies for our product candidates. Individuals working at the CROs with which we contract, as well as investigators at the sites at which our studies are conducted, are not our employees, and we have limited control over the amount or timing of resources that they devote to their programs. If our CROs, study investigators, and/or third-party sponsors fail to devote sufficient time and resources to studies of our product candidates, if we and/or our CROs do not comply with all GLP and GCP regulatory and contractual requirements, or if their performance is substandard, it could adversely affect the development of our product candidates.

Pursuant to the terms of our license for levosimendan, Orion is at present our sole manufacturing source for TNX-103; should they opt not to provide us the product, our license agreement provides for 24 months’ notice to the Company of same, to allow an alternative manufacturer to be brought onboard. We might engage other third-party suppliers and CMOs for the supply and manufacture of TNX-102, or other formulations we might develop. Accordingly, our business is susceptible to disruption, and our results of operations can be adversely affected, by any disruption in supply or other adverse developments in our relationship with Orion. If supply from Orion is delayed or terminated, or if its facilities suffer any damage or disruption, we may need to successfully qualify an alternative supplier in a timely manner in order to avoid disruption of our business. If we cannot obtain an alternate manufacturer in a timely manner, we would experience a significant interruption in supply of levosimendan, which could negatively affect our clinical trial conduct and other product development efforts and timelines, financial condition, results of operations and cash flows.

We have historically operated with a limited number of employees. As of December 31, 2024, we had four full-time employees and two part-time employees, and in the first quarter of 2025 added one additional full-time employee. Therefore, institutional knowledge is concentrated within a small number of employees. Our success depends in part on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel to continue the development, regulatory approval and commercialization of our product candidates. We will need to hire or contract with additional qualified personnel with expertise in preclinical testing, clinical research and testing, government regulation, formulation and manufacturing, and sales and marketing. Additionally, our future success is highly dependent upon the contributions of our senior management team. The loss of services of any of these individuals could delay or prevent the successful development of our product pipeline, completion of our planned clinical trials or the commercialization of our product candidates.

To commercialize our products, if approved, in the United States and other jurisdictions in which we may seek approvals, we must build our marketing, sales, managerial and other non-technical capabilities or make arrangements with third parties to perform these services, and we may not be successful in doing so. We have not decided upon a commercialization strategy in these areas. We have no experience in the sale and marketing of approved medical products and marketing the licensing of such products before FDA or other regulatory approval. We do not know of any third party that is prepared to distribute our products should they be approved. If we decide to establish our own commercialization capability, we will need to recruit, train and retain a marketing staff and sales force with sufficient technical expertise. We do not know whether we can establish a commercialization program at a cost that is acceptable in relation to revenue or whether we can be successful in commercializing our product. Factors that may inhibit our efforts to commercialize our products directly and without strategic partners include:

We are pursuing a multi-faceted IP strategy for levosimendan that includes filing patent applications in the U.S. and Canada, Europe, and multiple other countries that, if granted, could protect various uses and formulations of levosimendan In January 2022, the USPTO granted us a patent protecting claims for different uses of various cyclodextrin-based subcutaneous formulations of levosimendan, including a claim for its use in the treatment of PH-HFpEF patients. In addition, we received in March 2023 another patent protecting the use of levosimendan in the treatment of PH-HFpEF. Two subsequent patents expanded these protections on the use of levosimendan in the treatment of PH-HFpEF. Other patent applications are pending globally.

In 2026, the USPTO issued Tenax a Notice of Allowance for claims directed to the subcutaneous administration of levosimendan in a broad range of indications. The range of indications includes but is not limited to PH-HFpEF. In addition, we received in March 2023 another U.S. patent protecting the use of levosimendan in the treatment of PH-HFpEF. Two subsequent U.S. patents expanded these protections on the use of levosimendan in the treatment of PH-HFpEF. Other patent applications are pending globally, or will be granted in 2026 according to patent authorities in Canada in Europe.

Our strategy to maximize market exclusivity for imatinib relies on two forms of exclusivity. First, we have been granted Orphan Drug Designation for the treatment of PAH by the FDA which would provide seven years of regulatory exclusivity in the U.S. if our imatinib formulation is the first to receive FDA approval for PAH. In addition, we may file one or more patent applications to cover patentable subject matter that may result from our imatinib development. If granted, a patent would provide protection for 20 years from its filing date.

For the foreseeable future, to finance our operations, including possible acquisitions or strategic transactions, we expect to issue equity securities, resulting in the dilution of the ownership interests of our present stockholders. We are currently authorized to issue an aggregate of 400,000,000 shares of common stock and 10,000,000 shares of preferred stock. As of December 31, 2024, there were 3,420,906 shares of common stock outstanding, 19,874,360 shares underlying warrants with a weighted average exercise price of $5.77 per share, 31,882,671 shares underlying pre-funded warrants with an exercise price of $0.01 per share, and 3,126,750 shares underlying options with a weighted average exercise price of $6.96 per share. We may also issue additional shares of our common stock or other securities that are convertible into or exercisable for common stock in connection with hiring or retaining employees, or for other business purposes. The future issuance of any such additional shares of common stock or common stock equivalents may create downward pressure on the trading price of our common stock.

Certain provisions in our Certificate of Incorporation, as amended (the “Charter”), and our Fourth Amended and Restated Bylaws (the “Bylaws”), may make it difficult for a third party to acquire, or attempt to acquire, control of the Company, even if a change in control was considered favorable by the stockholders. For example, our Board of Directors has the authority to issue up to 10,000,000 shares of preferred stock. The Board can fix the price, rights, preferences, privileges and restrictions of the preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change in control transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders may be adversely affected. An issuance of shares of preferred stock may result in the loss of voting control to other stockholders.
