(the &#x201c;Company&#x201d;) was originally formed as a New Jersey corporation in 1967 under the name Rudmer, David &amp;amp; Associates, Inc., and subsequently changed its name to Synthetic Blood International, Inc. On June 17, 2008, the stockholders of Synthetic Blood International approved the Agreement and Plan of Merger dated April 28, 2008, between Synthetic Blood International and Oxygen Biotherapeutics, Inc., a Delaware corporation. Synthetic Blood International formed Oxygen Biotherapeutics on April 17, 2008 to participate in the merger for the purpose of changing the state of domicile of Synthetic Blood International from New Jersey to Delaware. Certificates of Merger were filed with the states of New Jersey and Delaware and the merger was effective June 30, 2008. Under the Plan of Merger, Oxygen Biotherapeutics was the surviving corporation and each share of Synthetic Blood International common stock outstanding on June 30, 2008 was converted into one share of Oxygen Biotherapeutics common stock. On September 19, 2014, the Company changed its name to Tenax Therapeutics, Inc.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;On November 13, 2013, the Company acquired, through its wholly-owned subsidiary, Life Newco, Inc., a Delaware corporation (&#x201c;Life Newco&#x201d;), certain assets of Phyxius Pharma, Inc., a Delaware corporation (&#x201c;Phyxius&#x201d;) pursuant to an Asset Purchase Agreement dated October 21, 2013 (the &#x201c;Asset Purchase Agreement&#x201d;), by and among the Company, Life Newco, Phyxius and the stockholders of Phyxius. Among these assets was a license between Phyxius and Orion Corporation, a global healthcare company incorporated under the laws of Finland (&#x201c;Orion&#x201d;), dated September 20, 2013, and that certain Side Letter, dated October 15, 2013, for the 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 (the &#x201c;Territory&#x201d;). On October 9, 2020 and January 25, 2022, the Company amended the license (as amended, the &#x201c;License&#x201d;), 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 in the License (together, the &#x201c;Product&#x201d;). Pursuant to the License, the Company and Orion will agree to a new trademark when commercializing levosimendan in either of these forms. The term of the License extends until 10 years after the launch of the Product in the Territory, provided that the License will continue after the end of the term in each country in the Territory until the expiration of Orion&#x2019;s patent rights in the Product in such country. In the event that no regulatory approval for the Product has been granted in the United States on or before September 20, 2030, however, either party will have the right to terminate the License with immediate effect. The Company intends to conduct an upcoming Phase 3 study in pulmonary hypertension patients utilizing one of these&#160;formulations. See &#x201c;Note 8 - Commitments and Contingencies&#x201d; below for a further discussion of the License.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;On January 15, 2021, the Company, Life Newco II, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (&#x201c;Life Newco II&#x201d;), PHPrecisionMed Inc., a Delaware corporation (&#x201c;PHPM&#x201d;) and Dr. Stuart Rich, solely in his capacity as holders&#x2019; representative ( the &#x201c;Representative&#x201d;), entered into an Agreement and Plan of Merger (the &#x201c;Merger Agreement&#x201d;) pursuant to which the Company acquired all of the equity of PHPM, a company developing pharmaceutical products containing imatinib for the treatment of pulmonary arterial hypertension (&#x201c;PAH&#x201d;) in the United States and the rest of the world. Under the terms of the Merger Agreement, Life Newco II merged with and into PHPM, with PHPM surviving as a wholly-owned subsidiary of the Company (the &#x201c;Merger&#x201d;). See &#x201c;Note&#160;7 - Merger&#x201d; below for a further discussion of the Merger.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Going Concern&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Management believes the accompanying condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (&#x201c;GAAP&#x201d;), which contemplate continuation of the Company as a going concern. The Company has an accumulated deficit of $281 million on March 31, 2022 and $278 million on December 31, 2021 and used cash in operations of $2.9 million and $3.2 million during the three months ended March 31, 2022 and 2021, respectively. The Company requires substantial additional funds to complete clinical trials and pursue regulatory approvals. Management is actively seeking additional sources of equity and/or debt financing; however, there is no assurance that any additional funding will be available.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;In view of the matters described above, recoverability of a major portion of the recorded asset amounts shown in the accompanying March 31, 2022 balance sheet is dependent upon continued operations of the Company, which in turn is dependent upon the Company&#x2019;s ability to meet its financing requirements on a continuing basis, to maintain present financing, and to generate cash from future operations. These factors, among others, raise substantial doubt about the Company&#x2019;s ability to continue as a going concern. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification of liabilities that might be necessary should the Company be unable to continue in existence.&lt;/p&gt;</us-gaap:BusinessDescriptionAndBasisOfPresentationTextBlock>

Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Certain information and footnote disclosures normally included in the Company&#x2019;s annual financial statements prepared in accordance with GAAP have been condensed or omitted. These condensed consolidated financial statement results are not necessarily indicative of results to be expected for the full fiscal&#160;year or any future period. &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px 0px 0px 0in; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;The accompanying unaudited condensed consolidated financial statements and related disclosures have been prepared with the presumption that users of the unaudited condensed consolidated financial statements have read or have access to the audited financial statements for the preceding fiscal year. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the Company&#x2019;s Form 10-K, which was filed with the United States Securities and Exchange Commission (&#x201c;SEC&#x201d;) on March 29, 2022, from which the Company derived the balance sheet data at December 31, 2021&lt;/p&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px 0px 0px 0in; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Use of Estimates&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with 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 unaudited condensed consolidated financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company&#x2019;s business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company&#x2019;s results of operations and financial position could be materially impacted.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Principles of Consolidation&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The accompanying unaudited condensed consolidated financial statements include the accounts and transactions of Tenax Therapeutics, Inc., Life Newco, Inc. and PHPrecisionMed Inc. All material intercompany transactions and balances have been eliminated in consolidation.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Cash and Cash Equivalents&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company considers all highly liquid instruments with a maturity date of three months or less, when acquired, to be cash equivalents.&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Liquidity and Capital Resources&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;On March 31, 2022, the Company had cash and cash equivalents of approximately $2.9 million. The Company used $2.9 million of cash for operating activities during the three months ended March 31, 2022 and had stockholders&#x2019; equity of $1.6 million, versus $4.2 million on December 31, 2021.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company expects to continue to incur expenses related to development of imatinib for PAH, levosimendan for pulmonary hypertension, and other potential indications, as well as identifying and developing other potential product candidates. Based on its resources on March 31, 2022, the Company believes that it has sufficient capital to fund its planned operations through the second quarter of calendar year 2022. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or licensing its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot provide assurance that it will be able to secure such additional financing on reasonable terms, or if available, that it will be sufficient to meet its needs.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to restrictive covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates or grant licenses on terms that may not be favorable to the Company.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The continued spread of COVID-19 globally could adversely affect the Company&#x2019;s clinical trial operations, including its ability to recruit and retain patients, principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 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 the Company&#x2019;s ability to initiate and/or complete planned clinical and preclinical studies in the future.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Any or all of the foregoing may have a material adverse effect on the Company&#x2019;s business and financial performance.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Loss Per Share&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Basic&#160;loss per share, which excludes antidilutive securities, is computed by dividing net loss by the weighted-average number of common shares outstanding for that particular period. In contrast, diluted loss per share considers the potential dilution that could occur from other equity instruments that would increase the total number of outstanding shares of common stock. Such amounts include shares potentially issuable under outstanding options, restricted stock and warrants.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The following outstanding options, restricted stock grants, convertible

new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company determines if an arrangement includes a lease at inception. Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term lease liabilities in the Company&#x2019;s condensed consolidated balance sheet as of March 31, 2022. Right-of-use assets represent the Company&#x2019;s right to use an underlying asset for the lease term and lease liabilities represent the Company&#x2019;s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company&#160;uses the incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use assets also include any lease payments made and exclude lease incentives. The Company&#x2019;s leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that the Company will exercise any such option. Lease expense is recognized on a straight-line basis over the expected lease term. The Company has elected to account for leases with an initial term of 12 months or less similar to previous guidance for operating leases, under which the Company will recognize those lease payments in the consolidated statements of operations and comprehensive loss on a straight-line basis over the lease term.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&lt;strong&gt;&lt;em&gt;Recent Accounting Pronouncements&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;In August 2020, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued accounting standards update (&#x201c;ASU&#x201d;) No. 2020-06,&#160;Debt-Debt with Conversion and Other Options (Subtopic 470-20)&#160;and&#160;Derivatives and Hedging-Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity&#x2019;s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption will be permitted. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements. &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px 0px 0px 0in; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;In December 2019, FASB issued ASU-2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, 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, with early adoption permitted. The Company adopted this standard on January 1, 2021. The Company&#x2019;s adoption of the new guidance did not have a material impact on its condensed consolidated financial statements&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;In June 2016, the FASB issued an accounting standard, ASU-2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, 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&#160;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. The Company does not believe the adoption of this standard will have a material impact on its condensed consolidated financial statements and related disclosures.&#160;&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The Company used $2.9 million of cash for operating activities during the three months ended March 31, 2022 and had stockholders&#x2019; equity of $1.6 million, versus $4.2 million on December 31, 2021.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company expects to continue to incur expenses related to development of imatinib for PAH, levosimendan for pulmonary hypertension, and other potential indications, as well as identifying and developing other potential product candidates. Based on its resources on March 31, 2022, the Company believes that it has sufficient capital to fund its planned operations through the second quarter of calendar year 2022. However, the Company will need substantial additional financing in order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends on its ability to raise additional funds through various potential sources, such as equity and debt financing, or licensing its product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through sources of capital similar to those previously described. The Company cannot provide assurance that it will be able to secure such additional financing on reasonable terms, or if available, that it will be sufficient to meet its needs.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;To the extent that the Company raises additional funds by issuing shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may incur significant interest expense and become subject to restrictive covenants in the related transaction documentation that may affect the manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates or grant licenses on terms that may not be favorable to the Company.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The continued spread of COVID-19 globally could adversely affect the Company&#x2019;s clinical trial operations, including its ability to recruit and retain patients, principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19 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 the Company&#x2019;s ability to initiate and/or complete planned clinical and preclinical studies in the future.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Any or all of the foregoing may have a material adverse effect on the Company&#x2019;s business and financial performance.&lt;/p&gt;</tenx:LiquidityAndCapitalResources>

Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term lease liabilities in the Company&#x2019;s condensed consolidated balance sheet as of March 31, 2022. Right-of-use assets represent the Company&#x2019;s right to use an underlying asset for the lease term and lease liabilities represent the Company&#x2019;s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, the Company&#160;uses the incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use assets also include any lease payments made and exclude lease incentives. The Company&#x2019;s leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that the Company will exercise any such option. Lease expense is recognized on a straight-line basis over the expected lease term. The Company has elected to account for leases with an initial term of 12 months or less similar to previous guidance for operating leases, under which the Company will recognize those lease payments in the consolidated statements of operations and comprehensive loss on a straight-line basis over the lease term.&lt;/p&gt;</us-gaap:LesseeLeasesPolicyTextBlock>
    <us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock contextRef="From2022-01-01to2022-03-31" id="fid_237">In August 2020, the Financial Accounting Standards Board (&#x201c;FASB&#x201d;) issued accounting standards update (&#x201c;ASU&#x201d;) No. 2020-06,&#160;Debt-Debt with Conversion and Other Options (Subtopic 470-20)&#160;and&#160;Derivatives and Hedging-Contracts in Entity&#x2019;s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity&#x2019;s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023. Early adoption will be permitted. The Company is currently evaluating the impact of this standard on its condensed consolidated financial statements. &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px 0px 0px 0in; text-align:justify;"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;In December 2019, FASB issued ASU-2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, 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, with early adoption permitted. The Company adopted this standard on January 1, 2021. The Company&#x2019;s adoption of the new guidance did not have a material impact on its condensed consolidated financial statements&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;In June 2016, the FASB issued an accounting standard, ASU-2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, 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&#160;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. The Company does not believe the adoption of this standard will have a material impact on its condensed consolidated financial statements and related disclosures.&#160;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

Unrealized gains and losses on investments are recognized in comprehensive income/(loss), unless an unrealized loss is considered to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary declines primarily resulting from interest rate changes. Realized gains and losses are reflected in other income in the condensed consolidated statements of comprehensive loss and are determined using the specific identification method with transactions recorded on a settlement date basis. Investments with original maturities at date of purchase beyond three months and which mature at or less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the balance sheet date are classified as long-term. As of March 31, 2022, the Company held no investments in marketable securities.&lt;/p&gt;</us-gaap:FairValueDisclosuresTextBlock>

The Lease was amended in August 2015 to extend the term for the 5,954 square foot rental. The current term began on March 1, 2016 and continued for 64 months to June 30, 2021. Rent payments began on July 1, 2016, following the conclusion of a four-month rent abatement period. The Company has two five-year options to extend the Lease and a one-time option to terminate the Lease thirty-six months after the commencement of the initial term if no additional space became available. On April 2, 2021, the Company negotiated a 3-year extension to the existing lease term, commencing July 1, 2021 (the &#x201c;Commencement Date&#x201d;). Beginning on the Commencement Date, the annual base rent was increased to $125,034 and will increase 2.5% annually for lease years 2 and 3.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new

For the three months ending March 31, 2022, the Company paid $32,809 in total lease expenses, including $1,551 for common area maintenance charges.&#160;&lt;/p&gt;</us-gaap:LeasesOfLesseeDisclosureTextBlock>

MERGER&lt;/strong&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;On January 15, 2021, the Company, Life Newco II, PHPM, and Dr. Rich, as Representative, entered into the Merger Agreement, pursuant to which, the Company acquired all of the equity of PHPM. Under the terms of the Merger Agreement, Life Newco II merged with and into PHPM, with PHPM surviving as a wholly-owned subsidiary of the Company. &lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;As consideration for the Merger, the stockholders of PHPM received (i) 1,892,905 shares of Company common stock, and (ii) 10,232 shares of the Company&#x2019;s Series B convertible preferred stock (&#x201c;Series B Stock&#x201d;), which were convertible into up to an aggregate of 10,232,000 shares of common stock (collectively, the &#x201c;Merger Consideration&#x201d;). To satisfy the Company&#x2019;s post-closing rights to closing adjustments and indemnification by PHPM and the former stockholders of PHPM pursuant to the Merger Agreement, 1,212,492 shares of common stock issuable upon conversion of the Series B Stock, which represented approximately 10% of the Merger Consideration, are subject to holdback restrictions for 24 months following closing of the transaction (the &#x201c;Holdback Shares&#x201d;).&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Pursuant to the Merger Agreement, the Company&#x2019;s Board of Directors, at its annual meeting of stockholders held on June 10, 2021, recommended to the Company&#x2019;s stockholders, and the stockholders approved, the conversion of the Series B Stock pursuant to the Certificate of Designation. As a result, each share of Series B Stock automatically converted into (i) 881.5 shares of common stock, and (ii) the right to receive up to 118.5 Holdback Shares, to be delivered 24 months after the date of issuance of the Series B Stock, subject to reduction for indemnification claims. &lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Pursuant to the terms of the Merger Agreement, on February 25, 2021, the Board appointed three directors designated by the PHPM representative to serve on the Board, Dr. Rich, the co-founder and Chief Executive Officer and a stockholder of PHPM, and Drs. Michael Davidson and Declan Doogan. In connection with the closing of the Merger, Dr. Rich also was appointed Chief Medical Officer of the Company.&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company evaluated this acquisition in accordance with ASC 805, Business Combinations, to determine whether the assets and operations of PHPM met the definition of a business. Included in the&#160;in-process research and development project is the historical know-how, formula&#160;protocols, designs, and procedures expected to be needed to complete the related&#160;phase of testing. The Company concluded that the in-process research and&#160;development project is an identifiable intangible asset that would be accounted for&#160;as a single asset in a business combination. The Company also qualitatively&#160;concluded that there is no fair value associated with the clinical research&#160;organization contract and the clinical manufacturing organization contract because&#160;the services are being provided at market rates and could be provided by multiple&#160;vendors in the marketplace. Therefore, all of the consideration in the transaction&#160;was allocated to the in-process research and development project. As such,&#160;the Company concluded that substantially all of the fair value of the gross assets&#160;acquired was concentrated in the single in-process research and development asset&#160;and the set was not a business.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company is planning to use the acquired asset to further its clinical development in an upcoming Phase 3 clinical trial for the treatment of patients with PAH. Although the acquired asset may have utility in other patient populations, future development decisions for the acquired asset will be contingent upon the results of the contemplated Phase 3 program for PAH. As such, the acquired asset does not have an alternative future use at the acquisition date. In accordance with ASC 730, Research and Development, the Company concluded the entire Purchase Price for the asset acquisition was an expense on the acquisition date.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The consideration transferred, assets acquired and liabilities assumed were recognized as follows:&lt;/p&gt;&lt;p

The License grants the Company an exclusive, sublicensable right to develop and commercialize pharmaceutical products containing levosimendan in the Territory and, pursuant to the October 9, 2020 and January 25, 2022 amendments, also includes two product dose forms containing levosimendan, in capsule and solid dosage form, and a subcutaneously administered product containing levosimendan, subject to specified limitations in the License. Pursuant to the License, the Company and Orion will agree to a new trademark when commercializing levosimendan in either of these forms. &lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The License also grants the Company a right of first refusal to commercialize new developments of the Product, including developments as to the formulation, presentation, means of delivery, route of administration, dosage or indication (i.e., line extension products). &lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Orion&#x2019;s ongoing role under the License includes sublicense approval, serving as the sole source of manufacture, holding a first right to enforce intellectual property rights in the Territory, and certain regulatory participation rights. Orion must notify the Company before the end of 2024 if it chooses not to exercise its right to supply oral formulations of levosimendan to the Company for commercialization in the Territory. Additionally, the Company must grant back to Orion a broad non-exclusive license to any patents or clinical trial data related to the Product developed by the Company under the License. The term of the License extends until 10 years after the launch of the Product in the Territory, provided that the License will continue after the end of the term in each country in the Territory until the expiration of Orion&#x2019;s patent rights in the Product in such country. In the event that no regulatory approval for the Product has been granted in the United States on or before September 20, 2030, however, either party will have the right to terminate the License with immediate effect.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Pursuant to the terms of the License, on November 13, 2013, the Company paid to Orion a non-refundable up-front payment in the amount of $1.0 million. The License also includes the following development milestones for which the Company must make non-refundable payments to Orion no later than 28 days after the occurrence of the applicable milestone event: (1) $2.0 million upon the grant of United States Food and Drug Administration approval, including all registrations, licenses, authorizations and necessary approvals, to develop and/or commercialize the Product in the United States; and (2) $1.0 million upon the grant of regulatory approval for the Product in Canada. Once commercialized, the Company is obligated to make certain non-refundable commercialization milestone payments to Orion, aggregating to up to $13.0 million, contingent upon achievement of certain cumulative net sales amounts in the Territory. The Company also must pay Orion tiered royalties based on net sales of the Product in the Territory made by the Company and its sublicensees. After the end of the License term, the Company must pay Orion a royalty based on net sales of the Product in the Territory for as long as the Company sells the Product in the Territory.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;As of March 31, 2022, the Company has not met any of the developmental milestones under the License and, accordingly, has not recorded any liability for the contingent payments due to Orion.&lt;/p&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

On March 13, 2014, the Company&#x2019;s stockholders approved an amendment to the 1999 Plan which increased the number of shares of common stock authorized for issuance under the 1999 Plan to a total of 200,000 shares, up from 15,000 previously authorized. On September 15, 2015, the Company&#x2019;s stockholders approved an additional amendment to the 1999 Plan which increased the number of shares of common stock authorized for issuance under the 1999 Plan to a total of 250,000 shares, up from 200,000 previously authorized. The 1999 Plan expired on June 17, 2018 and no new grants may be made under that plan after that date. However, unexpired awards granted under the 1999 Plan remain outstanding and subject to the terms of the 1999 Plan.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&lt;em&gt;1999 Plan Stock Options&lt;/em&gt;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;Stock options granted under the 1999 Plan may be ISOs or NSOs. ISOs could be granted only to employees. NSOs could be granted to employees, consultants and directors. Stock options under the 1999 Plan could be granted with a term of up to ten years and at prices no less than fair market value for ISOs and no less than 85% of the fair market value for NSOs. Stock options granted generally vest over one to three years.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;As of March 31, 2022, the Company has 36,317 options outstanding.

The option award will vest as follows: 50% upon initiation of a Phase 3 trial for levosimendan by June 30, 2022; and 50% upon initiation of a Phase 3 trial for imatinib by June 30, 2022. The options have a 10-year term and an exercise price of $1.97 per share, the July 6, 2021 closing price of our common stock. As of March 31, 2022, none of the vesting milestones have been achieved. The estimated fair value of this inducement stock option award was $178,291 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: risk-free interest rate of 1.37%, dividend yield of 0%, volatility factor for our common stock of 103.50% and an expected life of 10 years.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px"&gt;&#160;&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The employment inducement stock option award for 250,000 shares of common stock also was awarded in accordance with the employment inducement award exemption provided by Nasdaq listing rule 5635(c)(4) and was therefore not awarded under the Company&#x2019;s stockholder approved equity plan. The option award will vest as follows: 25% on the one-year anniversary of the CEO&#x2019;s employment start date and an additional 25% on each of the following three anniversaries of the CEO&#x2019;s employment start date, subject to continued employment. The options have a 10-year term and an exercise price of $1.97 per share, the July 6, 2021 closing price of our common stock. The estimated fair value of this inducement stock option award was $403,180 using a Black-Scholes option pricing model based on market prices and the following assumptions at the date of inducement option grant: risk-free interest rate of 1.13%, dividend yield of 0%, volatility factor for our common stock of 99.36% and an expected life of 7 years.&lt;/p&gt;&lt;p style="font-size:10pt;font-family:times new roman;margin:0px 0px 0px 0in"&gt;The Company granted an employment inducement stock option award for 250,000 shares of common stock to our chief medical officer on January 15, 2021. This employment inducement stock option was awarded in accordance with the employment inducement award exemption provided by Nasdaq listing rule 5635(c)(4) and was therefore not awarded under the Company&#x2019;s stockholder approved equity plan. The option award will vest as follows: 25% upon initiation of a Phase 3 trial; 25% upon database lock; 25% upon acceptance for review of an investigational NDA; and 25% upon approval. The options have a 10-year term and an exercise price of $1.78 per share, the January 15, 2021 closing price of our common stock. As of March 31, 2022, none of the remaining vesting milestones have been achieved.
