Organization, Consolidation and Presentation of Financial Statements [Abstract]
Liquidity, Plan of Operations and Going Concern	Note 2 – Liquidity, Plan of Operations and Going Concern The Company has experienced net losses and negative cash flows from operations each period since its inception. Through June 30, 2024, the Company had an accumulated deficit of $ 187,116 11,543 The Company has been engaged in developing its lipid nanocrystal (“LNC”) platform delivery technology and a pipeline of associated product candidates, including MAT2203, since 2011. To date, the Company has not obtained regulatory approval for any of its product candidates nor generated any revenue from product sales, and the Company expects to incur significant expenses to complete development of its product candidates. The Company may never be able to obtain regulatory approval for the marketing of any of its product candidates in any indication in the United States or internationally and there can be no assurance that the Company will generate revenues or ever achieve profitability. If the Company obtains U.S. Food and Drug Administration (“FDA”) approval for one or more of its product candidates, the Company expects that its expenses will continue to increase once the Company reaches commercial launch. The Company also expects that its research and development expenses will continue to increase as it moves forward with additional clinical studies for its current product candidates and development of additional product candidates. As a result, the Company expects to continue to incur substantial losses for the foreseeable future, and that these losses will be increasing. As of June 30, 2024, the Company had cash and cash equivalents of $ 4,216 10,097 250 The ability of the Company to continue as a going concern is dependent upon control over its operating expenses, anticipated proceeds from future sales of common stock through its At-The-Market Sales Agreement (“ATM”) with BTIG, LLC. and securing additional financing. While the Company believes in the viability of this strategy and believes the actions presently being taken by the Company provide the opportunity for it to continue as a going concern, there can be no assurance the Company will be successful in its implementation. In particular, utilization of the ATM may not be viable due to market conditions and new financing may not be available on acceptable terms, or at all. These consolidated financial statements do not include any adjustments related to the recoverability and classification of asset amounts or the amounts and classification of liabilities that might be necessary if the Company is unable to continue as a going concern.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5 - Fair Value Measurements The Company uses the fair value hierarchy to measure the value of its financial instruments. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The basis for fair value measurements for each level within the hierarchy is described below: ● Level 1 – Quoted prices for identical assets or liabilities in active markets. ● Level 2 – Quoted prices for identical or similar assets and liabilities in markets that are not active; or other model-derived valuations whose inputs are directly or indirectly observable or whose significant value drivers are observable. ● Level 3 – Valuations derived from valuation techniques in which one or more significant inputs to the valuation model are unobservable and for which assumptions are used based on management estimates. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. The carrying amounts of cash equivalents, current portion of restricted cash, prepaid expenses and other current assets, accounts payable, current portion of lease liabilities and accrued expenses approximate fair value due to the short-term nature of these instruments. A summary of the assets and liabilities carried at fair value in accordance with the hierarchy defined above is as follows: Schedule of Fair Value Measurement of Assets and Liabilities June 30, 2024 Total (Level 1) (Level 2) (Level 3) Fair Value Hierarchy June 30, 2024 Total (Level 1) (Level 2) (Level 3) Assets Marketable Debt Securities: U.S. Treasury Bonds $ 2,994 $ 2,994 $ — $ — U.S. Government Notes 7,103 — 7,103 — Total $ 10,097 $ 2,994 $ 7,103 $ — December 31, 2023 Total (Level 1) (Level 2) (Level 3) Fair Value Hierarchy December 31, 2023 Total (Level 1) (Level 2) (Level 3) Assets Marketable Debt Securities: U.S. Treasury Bonds $ 996 $ 996 $ — $ — U.S. Government Notes 7,973 — 7,973 — Total $ 8,969 $ 996 $ 7,973 $ — U.S. treasury bonds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices for identical assets in active markets. Marketable debt securities consisting of U.S. government notes are classified as Level 2 and are valued using quoted market prices in markets that are not active.

Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share attributable to common stockholders is computed using the more dilutive of (1) the two-class method or (2) the if-converted method. During the three and six months ended June 30, 2024 and 2023, diluted loss per common share is the same as basic loss per common share because, as the Company incurred a net loss during each period presented, the potentially dilutive securities from the assumed exercise of all outstanding stock options and warrants, would have an anti-dilutive effect. The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive as of June 30, 2024 and 2023: Schedule of Anti-dilutive Securities Excluded from Computation of Earning Per Share As of June 30, 2024 2023 Stock options 46,031,560 34,544,470 Warrants 33,333,334 — Total 79,364,894 34,544,470
