You should read the following discussion and analysis together with the consolidated financial statements and the related notes to those statements included in Item 8 - "Financial Statements and Supplementary Data". This discussion contains forward-looking statements that involve risks and uncertainties. As a result of many factors, such as those set forth under "Risk Factors" and elsewhere in this Annual Report on Form 10-K, our actual results may differ materially from those anticipated in these forward-looking statements.





Overview


Tenax Therapeutics was originally formed as a New Jersey corporation in 1967 under the name Rudmer, David & Associates, Inc., and subsequently changed its name to Synthetic Blood International, Inc. Effective June 30, 2008, we changed the domiciliary state of the corporation to Delaware and changed the Company name to Oxygen Biotherapeutics, Inc. On September 19, 2014, we changed the Company name to Tenax Therapeutics, Inc.

On November 13, 2013, we acquired a license granting Life Newco, our wholly-owned subsidiary, an exclusive, sublicensable right to develop and commercialize pharmaceutical products containing levosimendan, 2.5 mg/ml concentrate for solution for infusion / 5ml vial in the United States and Canada. On October 9, 2020 and January 25, 2022, we entered into amendments to the license to include two product dose forms containing levosimendan, in capsule and solid dosage form, and a subcutaneously administered product containing levosimendan, subject to specified limitations.

On January 15, 2021, we acquired 100% of the equity of PHPrecisionMed Inc., a Delaware corporation, or PHPM, with PHPM surviving as our wholly-owned subsidiary. As a result of the merger, we plan to develop and commercialize pharmaceutical products containing imatinib for the treatment of pulmonary arterial hypertension, or PAH.

Business Strategy


Having carefully considered alternatives within the ongoing strategic process announced in September 2022, and having raised capital to fund the Company through to the first quarter of 2024, the Company has recently elected to prioritize the Phase 3 testing of levosimendan, ahead of imatinib, with plans to commence a levosimendan Phase 3 study in 2023. Supporting this strategic decision is a U.S. Patent issued in March 2023, covering the use of IV levosimendan in patients with PH-HFpEF. This patent is the second levosimendan patent granted to Tenax since the start of 2022, and Tenax believes it provides strong precedent for the ongoing review of a third patent which may be granted in 2023 or 2024. This prioritization of the Phase 3 testing of levosimendan places the start of a Phase 3 imatinib trial likely outside the 2023 timeframe, pending fundraising to support that trial, as well as other strategic considerations.

The Company took steps to reduce its monthly operating expenses and conserve cash, as it commenced exploring strategic alternatives in late 2022. The Company has cancelled substantially all of its non-essential operating expenses such as consulting, its office lease, and dues and subscriptions and office supplies associated with that leased office.

Pending the outcome of our ongoing strategic process, the key elements of our business strategy are outlined below.

Efficiently conduct clinical development to establish clinical proof of principle in new indications, refine formulation, and commence Phase 3 testing of our current product candidates.

Levosimendan and imatinib have been approved and prescribed around the world for more than 20 years, but we believe their mechanisms of action have not been fully exploited, despite promising evidence they may significantly improve the lives of patients with pulmonary hypertension. We are conducting clinical development with the intent to establish proof of beneficial activity in cardiopulmonary diseases in which these therapeutics would be expected to have benefit for patients with diseases for which either no pharmaceutical therapies are approved at all, or in the case of PAH, where numerous expensive therapies generally offer a modest reduction of symptoms. Our focus is primarily on designing and executing formulation improvements, protecting these innovations with patents and other forms of exclusivity, and employing innovative clinical trial science to establish a robust foundation for subsequent development, product approval, and commercialization. We intend to submit marketing authorization applications following either one or two Phase 3 trials of levosimendan and, when appropriate, a single Phase 3 trial of imatinib. Our trials are designed to incorporate and reflect advanced clinical trial design science and the regulatory and advisory experience of our team. We intend to continue partnering with innovative companies, renowned biostatisticians and trialists, medical leaders, formulation and regulatory experts, and premier clinical testing organizations to help expedite development, and continue expanding into complementary areas when opportunities arise through our development, research, and discoveries. We also intend to continue outsourcing when designing and executing our research.

Efficiently explore new high-potential therapeutic applications, in particular where expedited regulatory pathways are available, leveraging third-party research collaborations and our results from related areas.

Levosimendan has shown promise in multiple disease areas in the two decades following its approval. Our own Phase 2 study and open-label extension has demonstrated that a formerly under-appreciated mechanism of action of levosimendan, its property of relaxing the venous circulation, brings about durable improvements in exercise capacity and quality of life, as well as other clinical assessments, in patients with heart failure with PH-HFpEF. We believe this patient population today has no pharmaceutical therapies available and we are committed to exploring potential clinical indications where our therapies may achieve best-in-class profile, and where we can address significant unmet medical needs.

We believe these factors will support approval by the FDA of these product candidates based on positive Phase 3 data. Through our agreement with our licensor, Orion, the originator of levosimendan for acute decompensated heart failure, we have access to a library of ongoing and completed trials and research projects, including certain documentation, which we believe, in combination with positive Phase 3 data we hope to generate in at least one indication, will support FDA approval of levosimendan. Likewise, the regulatory pathway for approval of imatinib for the treatment of PAH, as formulated by Tenax Therapeutics at the dose shown to be effective in a prior Phase 3 trial conducted by Novartis, allows Tenax to build on the dossier of research results already reviewed by the FDA. In order to achieve our objectives of developing these medicines for new groups of patients, we have established collaborative research relationships with investigators from leading research and clinical institutions, and our strategic partners. These collaborative relationships have enabled us to explore where our product candidates may have therapeutic relevance, gain the advice and support of key opinion leaders in medicine and clinical trial science, and invest in development efforts to exploit opportunities to advance beyond current clinical care. Additionally, we believe we will be able to leverage clinical safety data and preclinical results from some programs to support accelerated clinical development efforts in other areas, saving substantial development time and resources compared to traditional drug development.

Continue to expand our intellectual property portfolio.

Our intellectual property, and the confidentiality of all our Company information, is important to our business and we take significant steps to help protect its value. Our research and development efforts, both through internal activities and through collaborative research activities with others, aim to develop new intellectual property and enable us to file patent applications that cover new applications of our existing technologies, alone or in combination with existing therapies, as well as other product candidates.

Notice of Allowance and Patent

On February 1, 2023, the Company announced it was granted a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for its patent application with claims covering the use of IV levosimendan (TNX-101) in the treatment of PH-HFpEF. This patent was issued on March 21, 2023. At present, we have two patents pending, with additional decisions expected in 2023.



.



Enter into licensing or product co-development arrangements.

In addition to our internal development efforts, an important part of our product development strategy is to work with collaborators and partners to accelerate product development, maintain our low development and business operations costs, and broaden our commercialization capabilities globally. We believe this strategy will help us to develop a portfolio of high-quality product development opportunities, enhance our clinical development and commercialization capabilities, and increase our ability to generate value from our proprietary technologies.

As we focus on our strategic process, we also continue to position ourselves to execute upon licensing and other partnering opportunities. To do so, we will need to continue to maintain our strategic direction, manage and deploy our available cash efficiently and strengthen our collaborative research development and partner relationships.

Historically, we have financed our operations principally through equity and debt offerings, including private placements and loans from our stockholders. Based on our current operating plan, there is substantial doubt about our ability to continue as a going concern. Management has implemented certain cost-cutting measures as described above and is actively exploring a diverse range of strategic options to help drive stockholder value including, among other things, capital raises, a sale of our Company, merger, one or more license agreements, a co-development agreement, a combination of these, or other strategic transactions? however, there is no assurance that these efforts will result in a transaction or other alternative or that any additional funding will be available. Our ability to continue as a going concern depends on our ability to raise additional capital, through the sale of equity or debt securities and through collaboration and licensing agreements, to support our future operations. If we are unable to complete a strategic transaction or secure additional capital, we may be required to curtail our research and development initiatives and take additional measures to reduce costs.





COVID-19


The COVID-19 pandemic or similar epidemics could in the future, directly or indirectly, adversely impact our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to such illnesses, which could negatively impact our trials, increase our operating expenses, and have a material adverse effect on our financial results. We will continue to assess the potential impact of the COVID-19 pandemic on our business and operations, including our clinical operations and manufacturing activities.

General and Administrative Expenses

General and administrative expenses were $5.7 million for the year ended December 31, 2022, compared to $7.6 million for the same period in 2021. General and administrative expenses consist primarily of compensation for executive, finance, legal and administrative personnel, including stock-based compensation. Other general and administrative expenses include facility costs not otherwise included in research and development expenses, legal and accounting services, and other professional and consulting services. General and administrative expenses and percentage changes for the years ended December 31, 2022 and 2021, respectively, are as follows:





                                                              Increase/         % Increase/

Personnel costs decreased approximately $2.6 million for the year ended December 31, 2022, compared to the same period in the prior year. The decrease was primarily due to approximately $1.2 million in severance costs associated with the departure from the Company of the former CEO and other employees in 2021, as well as approximately $266,000 in noncash compensation expense resulting from the modification of the former CEO's outstanding stock options and the grant of an additional stock option on his separation date.

Legal and professional fees increased approximately $599,000 for the year ended December 31, 2022, compared to the same period in the prior year. Professional fees consist of the costs incurred for accounting fees, capital market expenses, consulting fees and investor relations services, as well as fees paid to the members of our Board of Directors.

Legal fees increased approximately $245,000 for the year ended December 31, 2022, as compared to the same period in the prior year. The increase was primarily due to capital market activities and IP related costs.

Professional fees increased approximately $354,000 for the year ended December 31, 2022, compared to the same period in the prior year. The increase was primarily attributable to increased consulting fees offset by a decrease in accounting, capital markets, and investor relations costs.

Other costs increased approximately $84,000 for the year ended December 31, 2022, compared to the same period in the prior year. Other costs include expenses incurred for franchise and other taxes, travel, supplies, insurance, depreciation and other miscellaneous charges. The increase was primarily attributable to increased costs for insurance offset by decreases in franchise and other taxes.

Facilities costs include costs paid for rent and utilities at our corporate headquarters in North Carolina. Facilities costs remained relatively unchanged for the years ended December 31, 2022 and 2021.

Research and Development Expenses

Research and development expenses were $5.4 million for the year ended December 31, 2022 as compared to $25.1 million for the same period in the prior year. Research and development expenses include, but are not limited to, (i) expenses incurred under agreements with CROs and investigative sites, which conduct our clinical trials and a substantial portion of our pre-clinical studies; (ii) the cost of supplying clinical trial materials; (iii) payments to contract service organizations, as well as consultants; (iv) employee-related expenses, which include salaries and benefits; and (v) facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities and equipment, depreciation of leasehold improvements, equipment, and other supplies. All research and development expenses are expensed as incurred. Research and development expenses and percentage changes for the years ended December 31, 2022 and 2021, respectively, are as follows:





                                                              Increase/         % Increase/

Clinical and preclinical development costs increased approximately $2.0 million for the year ended December 31, 2022 as compared to the same period in the prior year. Clinical and preclinical development costs consist of expenses associated with our Phase 2 HELP Study for levosimendan, which was completed during fiscal year 2020, the ongoing open label extension phase of this study, costs associated with our intravenous-to-oral levosimendan transition study, and development costs associated with the formulation for imatinib. The increase is primarily attributable to approximately $2.8 million in expenditures for CRO and development costs associated with imatinib offset by decreased costs of approximately $800,000 related to our modified release imatinib.

Personnel costs decreased $4,732 for the year ended December 31, 2022, as compared to the same period in the prior year. The decrease is primarily attributable to increased compensation costs offset by a decrease in annual bonus expense.

Other costs decreased approximately $21.8 million for the year ended December 31, 2022, as compared to the same period in the prior year. The decrease is primarily attributable to the recognition of in-process research and development acquired as part of the merger with PHPM in the prior period. There were no such expenses incurred in the current year.





Other Income and Expense


Other income and expense include non-operating income and expense items not otherwise recorded in our consolidated statement of comprehensive loss. These items include, but are not limited to, changes in the fair value of financial assets and derivative liabilities, interest income earned and fixed asset disposals. Other income decreased approximately $246,000 for the year ended December 31, 2022, compared to the same period in the prior year. This increase is due primarily to the forgiveness of our loan pursuant to the Paycheck Protection Program ("PPP Loan") in the prior period.

Liquidity, Capital Resources and Plan of Operation

We have incurred losses since our inception and, as of December 31, 2022, we had an accumulated deficit of approximately $290 million. 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 and imatinib for pulmonary hypertension and other potential indications, 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.

The process of conducting preclinical studies and clinical trials necessary to obtain approval from the FDA is costly and time consuming. The probability of success for each product candidate and clinical trial may be affected by a variety of factors, including, among other things, the quality of the product candidate's early clinical data, investment in the program, competition, manufacturing capabilities and commercial viability. As a result of the uncertainties discussed above, uncertainty associated with clinical trial enrollment and risks inherent in the development process, we are unable to determine the duration and completion costs of current or future clinical stages of our product candidates or when, or to what extent, we will generate revenues from the commercialization and sale of any of our product candidates. Development timelines, probability of success and development costs vary widely. We are currently focused on developing our two product candidates, levosimendan and imatinib; however, we will need substantial additional capital in the future in order to complete the development and potential commercialization of levosimendan and imatinib, and to continue with the development of other potential product candidates.

Liquidity


We have financed our operations since September 1990 through the issuance of debt and equity securities and loans from stockholders. We had total current assets of approximately $3.2 million and $5.7 million and working capital of approximately $1.4 million and $4.1 million as of December 31, 2022 and December 31, 2021, respectively. Our practice is to invest excess cash, where available, in short-term money market investment instruments and high quality corporate and government bonds.

Clinical and Preclinical Product Development

We are currently concluding an open label extension phase of the levosimendan HELP clinical trial, during which patients were transitioned from an intravenous to oral formulation of levosimendan for the treatment of pulmonary hypertension. We are also developing a new formulation of imatinib. Our ability to continue to pursue development of our products beyond the first quarter of calendar year 2024 will depend on obtaining license income or outside financial resources. There is no assurance that we will obtain any license agreement or outside financing or that we will otherwise succeed in obtaining any necessary resources.

The COVID-19 pandemic or a similar epidemic could in the future, directly or indirectly, adversely affect our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to respiratory illnesses if an outbreak occurs in their geography. Further, some patients may be unable to comply with clinical trial protocols if quarantines or travel restrictions impede patient movement or interrupt healthcare services, or if the patients become infected with COVID-19 themselves, which would delay our ability to complete our clinical trials or release clinical trial results. See "Item 1A - Risk Factors" above for additional discussion.





Financings


On February 3, 2023, we sold in a registered public offering (i) an aggregate of 6,959,444 shares of our common stock and pre-funded warrants to purchase an aggregate of 1,707,222 shares of our common stock and (ii) accompanying warrants to purchase up to an aggregate of 17,333,332 shares of our common stock at a combined offering price of $1.80 per share of common stock and associated warrant, or $1.799 per pre-funded warrant and associated warrant, resulting in gross proceeds to the Company of approximately $15.6 million. Net proceeds of the offering were approximately $14.1 million, after deducting the placement agent fees and estimated offering expenses payable by the Company.

On May 17, 2022, we sold 529,802 units in a private placement at a purchase price of $15.50 per unit for net proceeds of approximately $7.9 million. Each unit consisted of one unregistered pre-funded warrant to purchase one share of our common stock and one unregistered warrant to purchase one share of common stock.

On July 6, 2021, we sold 238,664 units in a private placement at a purchase price of $41.90 per unit for net proceeds of approximately $10 million. Each unit consisted of one unregistered pre-funded warrant to purchase one share of our common stock and one unregistered warrant to purchase one share of common stock.





Cash Flows



The following table shows a summary of our cash flows for the periods indicated:





                                                          Year ended December 31,

Net cash (used in) operating activities

Net cash used in operating activities was approximately $12.0 million for the year ended December 31, 2022 compared to approximately $10.9 million for the year ended December 31, 2021. The increase in cash used for operating activities was primarily due to an increase in our annual insurance premiums, trade accounts payable and accrued compensation as compared to the prior year.

Net cash (used in) provided by investing activities

Net cash used in or provided by investing activities was approximately $(2,323) for the year ended December 31, 2022, compared to approximately $454,000 in the year ended December 31, 2021. The decrease in cash provided by investing activities was primarily due to the purchase of fixed assets in the current period offset by sale of marketable securities in the prior period.

Net cash provided by financing activities

Net cash provided by financing activities was approximately $8.6 million for the year ended December 31, 2022 and is primarily attributable to net proceeds from the sale of stock units in our May 2022 private placement of $7.9 million and the exercise of stock warrants of $0.6 million.

Net cash provided by financing activities was approximately $9.7 million for the year ended December 31, 2021 and is primarily attributable to net proceeds from the sale of stock units in our July 2021 private placement of $9.2 million and the exercise of stock warrants of $0.5 million.

Operating Capital and Capital Expenditure Requirements

Our future capital requirements will depend on many factors that include, but are not limited to the following:





    ·   the initiation, progress, timing and completion of clinical trials for our
        product candidates and potential product candidates;

    ·   the outcome, timing and cost of regulatory approvals and the regulatory
        approval process;

    ·   delays that may be caused by changing regulatory requirements;

    ·   the number of product candidates we pursue;

    ·   the costs involved in filing and prosecuting patent applications and
        enforcing and defending patent claims;

    ·   the timing and terms of future collaboration, licensing, consulting or
        other arrangements that we may enter into;

    ·   the cost and timing of establishing sales, marketing, manufacturing and
        distribution capabilities;

    ·   the cost of procuring clinical and commercial supplies of our product
        candidates;

    ·   the extent to which we acquire or invest in businesses, products or
        technologies;

    ·   delays that may be caused by the global coronavirus pandemic or similar
        global societal disruptions; and

    ·   the possible costs of litigation.



Based on our working capital on December 31, 2022, and the financing completed on February 7, 2023 we believe we have sufficient capital on hand to continue to fund operations through to the first quarter of calendar year 2024.






         44

  Table of Contents



We will need substantial additional capital beyond the first quarter of calendar year 2024 and in the future in order to complete the regulatory approval and commercialization of levosimendan as well as to fund the development and commercialization of other future product candidates. Until we can generate a sufficient amount of product revenue, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings or corporate collaboration and licensing arrangements. Such funding, if needed, may not be available on favorable terms, if at all. In the event we are unable to obtain additional capital, we may delay or reduce the scope of our current research and development programs and other expenses. As a result of our historical operating losses and expected future negative cash flows from operations, we have concluded that there is substantial doubt about our ability to continue as a going concern. Similarly, the report of our independent registered public accounting firm on our December 31, 2022 consolidated financial statements include an explanatory paragraph indicating that there is substantial doubt about our ability to continue as a going concern. Substantial doubt about our ability to continue as a going concern may materially and adversely affect the price per share of our common stock and make it more difficult to obtain financing.

If adequate funds are not available, we may also be required to eliminate one or more of our clinical trials, delaying approval of levosimendan or our commercialization efforts. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience additional significant dilution, and debt financing, if available, may involve restrictive covenants. To the extent that we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to our technologies or our product candidates or grant licenses on terms that may not be favorable to us. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. We may also consider strategic alternatives, including a sale of our company, merger, other business combination or recapitalization.

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, including the use of structured finance, special purpose entities or variable interest entities.

Summary of Critical Accounting Policies

Use of Estimates-The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Preclinical Study and Clinical Accruals-We estimate our preclinical study and clinical trial expenses based on the services received pursuant to contracts with several research institutions and CROs that conduct and manage preclinical and clinical trials on our behalf. The financial terms of the agreements vary from contract to contract and may result in uneven expenses and payment flows. Preclinical study and clinical trial expenses include the following:





    ·   fees paid to CROs in connection with clinical trials;

    ·   fees paid to research institutions in conjunction with preclinical
        research studies; and

    ·   fees paid to contract manufacturers and service providers in connection
        with the production and testing of active pharmaceutical ingredients and
        drug materials for use in preclinical studies and clinical trials.



Stock-Based Compensation-We account for stock-based awards to employees in accordance with Accounting Standards Codification, or ASC, 718, Compensation - Stock Compensation, which provides for the use of the fair value-based method to determine compensation for all arrangements where shares of stock or equity instruments are issued for compensation. Fair values of equity securities are determined by management based predominantly on the trading price of our common stock. The values of these awards are based upon their grant-date fair value. That cost is recognized over the period during which the employee is required to provide service in exchange for the reward.

We account for equity instruments issued to non-employees in accordance with ASC 505-50, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services. Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustment as the underlying equity instruments vest.

Recent Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board, or the FASB, issued an accounting standard intended to simplify accounting for income taxes. It removes certain exceptions to the general principles in Topic 740, Income Taxes, and amends existing guidance to improve consistent application. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 and early adoption is permitted. We adopted this standard on January 1, 2021. Our adoption of the new guidance did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued an accounting standard that amends how credit losses are measured and reported for certain financial instruments that are not accounted for at fair value through net income. This standard requires that credit losses be presented as an allowance rather than as a write-down for available-for-sale debt securities and will be effective for interim and annual reporting periods beginning January 1, 2023, with early adoption permitted. A modified retrospective approach is to be used for certain parts of this guidance, while other parts of the guidance are to be applied using a prospective approach. We do not believe the adoption of this standard will have a material impact on our consolidated financial statements and related disclosures.
