Organization, Principal Activities, and Basis of Presentation [Abstract]
Organization, Principal Activities, and Basis of Presentation	1. Organization, Principal Activities and Basis of Presentation Allarity Therapeutics, Inc. and Subsidiaries (the “Company”) is a clinical stage pharmaceutical company that develops drugs for the personalized treatment of cancer using drug specific companion diagnostics generated by its proprietary drug response predictor technology, DRP ® The Company’s principal operations are located at Venlighedsvej 1, 2970 Horsholm, Denmark. The Company’s business address in the Unites States is located at 24 School Street, 2 nd (a) Reverse Stock Split On April 9, 2024, the Company effected a 1-for-20 reverse stock split of the shares of its Common Stock (the “Reverse Stock Split”). All historical share and per share amounts reflected throughout the Financial Statements (as defined below in 1(b)) and these notes to the financial statements have been adjusted to reflect the Reverse Stock Split. See Note 10(a). (b) Liquidity and Going Concern The accompanying unaudited condensed interim consolidated financial statements (the “Financial Statements”) have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. The Financial Statements do not reflect any adjustments relating to the recoverability and reclassification of assets and liabilities that might be necessary if the Company is unable to continue as a going concern. Pursuant to the requirements of Accounting Standard Codification (ASC) 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date of the Financial Statements, and (1) is probable that the plan will be effectively implemented within one year after the date the financial statements are issued, and (2) it is probable that the plan, when implemented, will mitigate the relevant condition or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued. Certain elements of the Company’s operating plan to alleviate the conditions that raise substantial doubt are outside of the Company’s control and cannot be included in management’s evaluation under the requirements of ASC 205-40. Since inception, the Company has devoted substantially all its efforts to business planning, research and development, clinical expenses, recruiting management and technical staff, and securing funding via collaborations. The Company has historically funded its operations with proceeds received from its collaboration arrangements, sale of equity capital and proceeds from sales of convertible notes. The Company has incurred significant losses and has an accumulated deficit of $98.3 million as of March 31, 2024. As of March 31, 2024, the Company’s cash of $312 is insufficient to fund the Company’s current operating plan and planned capital expenditures for the next 12 months. These conditions give rise to substantial doubt over the Company’s ability to continue as a going concern. Management’s plans to mitigate the conditions or events that raise substantial doubt include additional funding through public equity, private equity, debt financing, collaboration partnerships or other sources. On March 19, 2024, the Company entered into an At-The-Market Issuance Sales Agreement with Ascendiant Capital Markets, LLC to sell shares of the Company’s Common Stock, with aggregate gross sales proceeds of up to $22 million, from time to time, through an “at-the-market” equity offering program (the “ATM Offering”). As of March 31, 2024, the Company has up to approximately $21.29 million remaining in aggregate gross proceeds that can be issued through the ATM Offering. In light of the Company’s cash position as of the date of this Quarterly Report, the Company does not have sufficient funds for its current operations and planned capital expenditures. As discussed above, the Company intends to seek capital through sale of its securities or other sources. There are no assurances, however, that the Company will be successful in raising additional working capital, or if it is able to raise additional working capital, it may be unable to do so on commercially favorable terms. The Company’s failure to raise capital or enter into other such capital raising arrangements if and when needed would have a negative impact on its business, results of operations and financial condition and its ability to develop its product candidates. Although management continues to pursue its funding plans, there is no assurance that the Company will be successful in obtaining sufficient funding to fund continuing operations on terms acceptable to the Company, if at all. Accordingly, based upon cash on hand at March 31, 2024, the Company does not have sufficient funds to finance its operations for at least twelve months from March 31, 2024 and therefore has concluded that substantial doubt exists about the Company’s ability to continue as a going concern. (c) Basis of Presentation The Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as established by the Financial Accounting Standards Board (the “FASB”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (the “SEC”). The Financial Statements contain all normal and recurring adjustments necessary to state fairly the consolidated balance sheet, results of operations and comprehensive loss, statements of changes in redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows of the Company for the interim periods presented. Except as otherwise disclosed, all such adjustments consist only of those of a normal recurring nature. Operating results for the three months ended March 31, 2024, are not necessarily indicative of the results that may be expected for the current fiscal year ending December 31, 2024. The financial data presented herein do not include all disclosures required by U.S. GAAP and should be read in conjunction with the audited consolidated financial statements and accompanying notes as of and for the fiscal years ended December 31, 2023 and 2022, thereto included in the Company’s Annual Report on Form 10-K, as amended (the “Form 10-K”) initially filed with the SEC on March 8, 2024. The preparation of the Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The results of operations and cash flows for the interim periods included in the Financial Statements are not necessarily indicative of the results to be expected for any future period or the entire fiscal year. (d) Risks and Uncertainties The Company is subject to risks common to companies in the biotechnology industry, including but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval for any drug product candidate that it may identify and develop, the need to successfully commercialize and gain market acceptance of its product candidates, dependence on key personnel and collaboration partners, protection of proprietary technology, compliance with government regulations, development by competitors of technological innovations, and the ability to secure additional capital to fund operations. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval prior to commercialization. Even if the Company’s research and development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies There have been no new or material changes to the significant accounting policies discussed in the Form 10-K, that are of significance, or potential significance, to the Company. (a) Organization and Principles of Consolidation The financial statements include the accounts of the Company and its wholly owned subsidiaries: Name Country of Incorporation Allarity Acquisition Subsidiary Inc. United States Allarity Therapeutics Europe ApS (formerly Oncology Venture Product Development ApS)* Denmark Allarity Therapeutics Denmark ApS (formerly OV-SPV2 ApS)* Denmark MPI Inc.* (1) United States * Wholly-owned subsidiary of Allarity Acquisition Subsidiary, Inc. (1) In the process of being dissolved because inactive. All intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation. ( b The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting years. Significant estimates and assumptions reflected in the Financial Statements include, but are not limited to, the fair value of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, warrants, convertible debt, convertible promissory note, and the accrual for research and development expenses, fair values of acquired intangible assets and impairment review of those assets, share based compensation expense, and income tax uncertainties and valuation allowances. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering reasonable changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known and if material, their effects are disclosed in the notes to the financial statements. Actual results could differ from those estimates or assumptions. (c) Foreign currency and currency translation The functional currency is the currency of the primary economic environment in which an entity’s operations are conducted. The Company and its subsidiaries operate mainly in Denmark and the United States. The functional currencies of the Company’s subsidiaries are their local currency. The Company’s reporting currency is the U.S. dollar. The Company translates the assets and liabilities of its Denmark subsidiaries into the U.S. dollar at the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate in effect during each monthly period. Unrealized translation gains and losses are recorded as a cumulative translation adjustment, which is included in the condensed consolidated statements of changes in redeemable convertible preferred stock and stockholders’ equity (deficit) as a component of accumulated other comprehensive loss. Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods. Adjustments that arise from exchange rate translations are included in other comprehensive loss in the condensed consolidated statements of operations and comprehensive loss as incurred. Adjustments that arise from exchange rate translations are included in other comprehensive loss in the consolidated statements of operations and comprehensive loss as incurred. The Company recorded a foreign exchange translation gain of $25 and $84, included in accumulated other comprehensive loss for the three month periods ended March 31, 2024 and 2023, respectively. (d) Concentrations of credit risk and of significant suppliers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company maintains its cash in financial institutions in amounts that could exceed government-insured limits. The Company does not believe it is subject to additional credit risks beyond those normally associated with commercial banking relationships. The Company has not experienced losses on its cash accounts and management believes, based upon the quality of the financial institutions, that the credit risk regarding these deposits is not significant. The Company is dependent on third-party manufacturers to supply products for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply its requirements for supplies and raw materials related to these programs. These programs could be adversely affected by a significant interruption in these manufacturing services or the availability of raw materials. (e) Cash Cash consists primarily of highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. (f) Accumulated other comprehensive loss Accumulated other comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with shareholders. The Company records unrealized gains and losses related to foreign currency translation and instrument specific credit risk as components of other accumulated comprehensive loss in the condensed consolidated statements of operations and comprehensive loss. During the three months ended March 31, 2024, and 2023, the Company’s other comprehensive gain was comprised of currency translation adjustments. (g) Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each reporting date, the Company evaluates whether a potential loss amount or a potential loss range is probable and reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The Company expenses costs as incurred in relation to such legal proceedings as general and administrative expense within the condensed consolidated statements of operations and comprehensive loss. (h) Reclassification During the three months ended March 31, 2023, we have reclassified financing costs of $9 from other income and expenses to general and administrative expenses with no net impact upon our operating results or cash flows for either the current or prior periods. (i) Recently Issued Accounting Pronouncements Changes to U.S. GAAP are established by the FASB in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. All other ASUs issued through the date of the Financial Statements were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s condensed consolidated financial position and results of operations.

Convertible promissory note due to Novartis On January 26, 2024, we received a termination notice from Novartis Pharma AG, a company organized under the laws of Switzerland (“Novartis”) due to a material breach of that certain license agreement dated April 6, 2018, as amended to date (the “License Agreement”).

Convertible senior promissory notes due to 3i, LP (3i”)	6. Convertible senior promissory notes due to 3i, LP (3i”) (a) 3i Convertible Senior Promissory Notes (2024) (collectively the “2024 Notes”) During the three months ended March 31, 2024, the Company entered into a Securities Purchase Agreement (the “SPA”), as amended, with 3i, pursuant to which three senior convertible promissory notes were issued as follows: i. On January 18, 2024, in an aggregate principal amount of $440 due on January 18, 2025, and with a set conversion price of $8.95 per share, for an aggregate purchase price of $400, representing an approximate 10% original issue discount (the “First Note”). ii. On February 13, 2024, in an aggregate principal amount of $440 due on February 13, 2025, and with a set conversion price of $8.10 per share, for an aggregate purchase price of $400, representing an approximately 10% original issue discount (the “Second Note”). iii. On March 14, 2024, in an aggregate principal amount of $660 due on March 14, 2025, and with a set conversion price of $7.00 per share, for an aggregate purchase price of $600, representing an approximately 10% original issue discount (the “Third Note”). The Company agreed to use the net proceeds from the sale of the 2024 Notes, among other things, for accounts payable and for working capital purposes. Unless the transaction documents state otherwise, the Company may not prepay any portion of the principal amount of the 2024 Notes without 3i’s prior written consent. The Company evaluated the terms of the 2024 Notes as required pursuant to ASC 570, 480, 815 and ASU 2020-06, and concluded the 2024 Notes will be recorded at $1,340, net of share issuance costs of $40, and accreted to redemption value of $440 on January 18, 2025, $440 on February 13, 2025, and $660 on March 14, 2025, using the effective interest method. The total debt discount of $140 and costs of $60 of the 2024 Notes are being amortized to interest expense over the one year term of each tranche of the debt. As of March 31, 2024, we have recorded $37 as interest expense. The balance outstanding at March 31, 2024 is $1,377. See Note 17(a) iii. The Company agreed to pay interest to 3i on the aggregate unconverted and then outstanding principal amount of the 2024 Notes at the rate of 8% per annum with interest payments commencing one month after the initial receipt of net proceeds. The interest on each of the 2024 Notes is payable in cash or, at the 3i’s option, in shares of our Common Stock, at the 90% of the lowest VWAP during the previous ten trading days that is immediately prior to the interest payment dates. Under the terms of the 2024 Notes, 3i has the exclusive right to choose whether to receive interest payments in cash or as shares of our Common Stock. Conversion of the 2024 Notes The Company has committed to keeping enough of its authorized but unissued shares of Common Stock available exclusively for conversion of the 2024 Notes. The number of shares to be issued upon conversion of the 2024 Notes will be calculated by dividing the outstanding principal amount of the respective 2024 Notes to be converted by their respective conversion prices as described above. The conversion prices of the 2024 Notes are subject to adjustment to equal the price of subsequent equity sales. 3i’s ownership percentage of our shares of Common Stock is limited to no more than 4.99%, as determined according to Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and its accompanying rules. Additionally, the Company cannot issue shares of its Common Stock in relation to the 2024 Notes transaction, including shares due upon the 2024 Notes conversion or otherwise, that exceed 19.99% of its total outstanding shares of Common Stock, unless otherwise permitted by the 2024 Notes and related documents. Redemption Subject to the provisions of the 2024 Notes, if, at any time while the 2024 Notes are outstanding, the Company engages in one or more subsequent financings, 3i may require us to first use up to 100% of the gross proceeds of such financing to redeem all or a portion of the 2024 Notes at 105%. However, if the Company were to raise capital in the ATM Offering, 3i may request up to 20% of the proceeds to redeem the Series A Convertible Preferred Stock (the “Series A Preferred Stock”) at the stated value. Events of Default The 2024 Notes include customary event of default provisions and provide for a mandatory default provision. Upon the occurrence of an event of default, 3i may require the Company to pay in cash the “Mandatory Default Amount” which is defined in the 2024 Notes to mean the sum of (a) the greater of (i) the outstanding principal amount of the First Note, the Second Note and the Third Note, plus all accrued and unpaid interest thereon, divided by the lesser of (i) $8.95 in the case of the First Note, $8.10 in the case of the Second Note, and $7.00 in the case of the Third Note, or (ii) 85% of the average of the three lowest VWAPs during the 10 trading days ending on the trading day that is immediately prior to the applicable date the Mandatory Default Amount is either (A) demanded or otherwise due or (B) paid in full, whichever has a lower conversion price, multiplied by the highest closing price for the Company’s shares of Common Stock on the trading market during the period beginning on the date of first occurrence of the event of default and ending on the date the Mandatory Default Amount is paid in full, or (ii) 130% of the sum of the outstanding principal amount of the First and Second Note, plus accrued and unpaid interest hereon, and (b) all other amounts, costs, expenses and liquidated damages due in respect of the First Note, the Second Note and the Third Note. Negative Covenants While any of the 2024 Notes are outstanding, without prior written consent from 3i and holders of at least 50.01% of the outstanding 2024 Notes, the Company is restricted from (i) incurring any debt exceeding $250 in total; (ii) creating any liens on their property, except for permitted ones; (iii) making amendments to their charter documents that adversely affect 3i’s rights; (iv) repurchasing the Company’s shares of Common Stock or equivalents, except under specific conditions related to conversion shares under the Second Note and equity incentives for departing officers and directors, capped at $50 in total; (v) repurchasing or acquiring any indebtedness other than the First Note and the Second Note, unless it is done pro-rata; (vi) paying cash dividends or distributions on their equity securities; (vii) engaging in transactions with any affiliates or related parties, unless permitted by the SPA; and (viii) entering into agreements related to the above restrictions. Registration Rights The Company agreed to register with the SEC the resale of its shares of the Common Stock issuable upon conversion of the 2024 Notes pursuant to the SPA. We agreed to reimburse 3i of reasonable attorneys’ fees and expenses incurred by 3i for significant work in connection with the closings contemplated in the SPA. The SPA also provides for indemnification of 3i if it incurs losses, liabilities, obligations, claims, contingencies, damages, costs and expenses related to, among other things, a breach by us of any of our representations, warranties or covenants under the SPA. (b) 3i Convertible Secured Promissory Notes (2023) On November 22, 2022, the Company entered into a Secured Note Purchase Agreement (“Purchase Agreement”) with 3i, whereby the Company authorized the sale and issuance of three Secured Promissory Notes (each a “Note” and collectively, the “Notes”). Effective November 28, 2022, the Company issued: (1) a Note in the principal amount of $1,667 as payment of $1,667 due to 3i in Alternative Conversion Floor Amounts (as defined in the Notes) that began to accrue on July 14, 2022; and (2) a Note in the principal amount of $350 in exchange for cash. Effective December 30, 2022, the Company issued an additional Note in the principal amount of $650 in exchange for cash. Each Note matured on January 1, 2024, carried an interest rate of 5% per annum, and was secured by all of the Company’s assets pursuant to a security agreement (the “Security Agreement”). In addition, the Holder may exchange the Notes for the Company’s shares of Common Stock at an exchange price equal to the lowest price per share of the equity security sold to other purchasers, rounded down to the nearest whole share, if the Company concludes a future equity financing prior to the maturity date or other repayment of such promissory note. Lastly, each Note and interest earned thereon may be redeemed by the Company at its option at any time or the holder may demand redemption if a) the Company obtains gross proceeds of at least $5 million in a financing in an amount of up to 35% of the gross proceeds of the financing or b) there is an Event of Default (as defined in the Note agreement). Discounts to the principal amounts are included in the carrying value of the Notes and amortized to interest expense over the contractual term of the underlying debt. During 2022, the Company recorded a $34 debt discount upon issuance of the Notes related to legal fees paid that were capitalized as debt issuance costs. For the three months ended March 31, 2023, interest expense totaled $43, comprised of $33 for contractual interest and $10 for the amortization of the debt discount. The 3i Convertible Secured Promissory Notes were paid in full and cancelled on April 21, 2023.

Preferred Stock	7. Preferred Stock A. Series A Convertible Preferred Stock and Common Stock Purchase Warrants (a) Amendments to Series A Convertible Preferred Stock i. Determination of Conversion Price Adjustments for Series A Preferred Stock On December 9, 2022, the Company and 3i entered into a letter agreement (the “2022 Letter Agreement”) which provided that pursuant to Section 8(g) of the Company’s Certificate of Designations for the Series A Preferred Stock (the “COD”), the Company and 3i agreed that the Conversion Price (as defined in the COD) was modified to mean the lower of: (i) the Closing Sale Price (as defined in the COD) on the trading date immediately preceding the Conversion Date (as defined in the COD) and (ii) the average Closing Sale Price (as defined in the COD) of the common stock for the five trading days immediately preceding the Conversion Date (as defined in the COD), for the Trading Days (as defined in the COD) through and inclusive of January 19, 2023. Any conversion which occurs shall be voluntary at the election of 3i, which shall evidence its election as to the Series A Preferred Stock being converted in writing on a conversion notice setting forth the then Minimum Price (as defined in the COD). Management determined that the adjustment made to the Conversion Price is not a modification of the COD which allows for adjustments to the Conversion Price (as defined in the COD) at any time by the Company and the other terms of the COD remained unchanged. On January 23, 2023, the Company and 3i amended the 2022 Letter Agreement, to provide that the modification of the term Series A Preferred Stock Conversion Price (the “Series A Preferred Stock Conversion Price”) to mean the lower of: (i) the Closing Sale Price (as defined in the COD) on the trading date immediately preceding the Conversion Date (as defined in the COD and (ii) the average Closing Sale Price (as defined in the COD) of the Company’s shares of Common Stock for the five trading days immediately preceding the Conversion Date (as defined in the COD), for the Trading Days (as defined in the COD) will be in effect until terminated by the Company and 3i. ii.

Also on January 14, 2024, the conversion price of the outstanding 1,417 shares of Series A Preferred Stock was revised from $20.00 to $8.95. The Company filed the Fifth Certificate of Amendment to Amended and Restated COD (the “Fifth Amendment”) with the Secretary of State of the State of Delaware to reflect the new conversion price of the Series A Preferred Stock of $8.95. As of January 14, 2024, the Company used the Black-Scholes option pricing model to determine the fair value of the 1,417 Series A Preferred Stock outstanding at $1,970 versus their carrying value of $1,742. Accordingly, the Company has recorded a deemed dividend of $228 as at January 14, 2024. At a stated value of $1,080 for each share of Series A Preferred Stock, the revised price of $8.95 per share results in the 1,417 shares being convertible into 170,952 shares of Common Stock as of January 14, 2024.

Royalty Payments In addition to the milestone payments described above, the Company has agreed to pay Eisai royalties based on annual incremental sales of product derived from Stenoparib in an amount between 5% and 10% of annual sales of between $0 The Company is obligated to pay royalties under the agreement on a country-by-country and product-by-product basis for a period that commences with the first commercial sale of a product until the later of (i) the expiration of the last to expire valid claim of any licensed patent covering such licensed product in such country; or, (ii) the expiration of regulatory-based exclusivity for such licensed product in such country or (iii) the 15 year anniversary of the date of first commercial sale of such licensed product in such country. However, the agreement may be terminated sooner without cause by the Company upon 120 days prior written notice, or upon written notice of a material breach of the agreement by Eisai that is not cured within 90 days (30 days for a payment default). Eisai also has the right to terminate the agreement upon written notice of a material breach of the agreement by the Company that is not cured within 90 days (30 days for a payment default) or if the Company files for bankruptcy. By an amendment effective as of August 3, 2021, and executed by Eisai on August 23, 2021, Eisai also has the right to terminate the agreement if the Company does not complete a Phase 2 clinical trial before December 31, 2022, unless we elect to pay a $1,000 extension payment (the “Extension Payment”). Notwithstanding the foregoing, in the event the Company fails to enroll and dose at least 30 patients with the first dose of cancer drug in the ongoing Phase 2 Ovarian Cancer Clinical Trial by July 1, 2022, then the Extension Payment will be due and payable in fully by July 30, 2022. In addition, if the Company fails to achieve successful completion of first Phase 2 Clinical Trial prior to December 31, 2022, and does not elect to pay the Extension Payment then Eisai may terminate the agreement in its sole discretion pursuant to the terms of the amendment.

The Company commenced a Phase 2 clinical trial April 15, 2019, and as of the date of the Financial Statements, Eisai has not indicated an intention to exercise its repurchase option.

Loss per Share of Common Stock [Abstract]
Loss per share of common stock	13. Loss per share of common stock Basic loss per share is derived by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share includes the effect, if any, of the potential exercise or conversion of securities, such as warrants and stock options, which would result in the issuance of incremental shares of common stock unless such effect is anti-dilutive. In calculating the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remained the same for both calculations because when a net loss exists, dilutive shares are not included in the calculation. Potentially dilutive securities outstanding, as determined by the latest applicable conversion price, that have been excluded from diluted loss per share due to being anti-dilutive include the following: March 31, March 31, 2024 2023 Warrants and stock options 886,104 94 Series A Convertible Preferred stock 535,286 190 Series C Convertible Preferred stock — 48 Convertible debt 213,549 1,984 1,634,939 2,316

Financial Instruments	14. Financial Instruments The following tables present information about the Company’s financial instruments measured at fair value on a recurring basis and indicate the level of the fair value hierarchy used to determine such fair values: Fair Value Measurements as of March 31, 2024, Using: Level 1 Level 2 Level 3 Total Liabilities: Warrant liability $ — $ — $ (1,107 ) $ (1,107 ) Derivative warrant liability — — (1,556 ) (1,556 ) $ — $ — $ (2,663 ) $ (2,663 ) Fair Value Measurements as of December 31, 2023, Using: Level 1 Level 2 Level 3 Total Liabilities: Warrant liability $ — $ — $ (2,263 ) $ (2,263 ) Derivative warrant liability — — (820 ) (820 ) $ — $ — $ (3,083 ) $ (3,083 ) Methods used to estimate the fair values of our financial instruments, not disclosed elsewhere in the Financial Statements, are as follows: When available, the Company’s marketable securities are valued using quoted prices for identical instruments in active markets. If the Company is unable to value its marketable securities using quoted prices for identical instruments in active markets, the Company values its investments using broker reports that utilize quoted market prices for comparable instruments. The Company has no financial assets or liabilities measured using Level 2 inputs. Financial assets and liabilities are considered Level 3 when their fair values are determined using pricing models, discounted cash flow methodologies, or similar techniques, and at least one significant model assumption or input is unobservable. The Company recognizes its derivative liabilities as Level 3 and values its derivatives using the methods discussed below. While the Company believes that its valuation methods are appropriate and consistent with other market participants, it recognizes that the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The primary assumptions that would significantly affect the fair values using terms in the notes that are subject to volatility and market price of the underlying shares of Common Stock. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. The Company’s policy is to recognize transfers into and out of levels within the fair value hierarchy at the date the actual event or change in circumstances that caused the transfer occurs. When a determination is made to classify an asset or liability within Level 3, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. There were no transfers between Level 1 or Level 2 during the three-month periods ended March 31, 2024 and 2023.

Summary of Significant Accounting Policies [Abstract]
Organization and Principles of Consolidation	(a) Organization and Principles of Consolidation The financial statements include the accounts of the Company and its wholly owned subsidiaries: Name Country of Incorporation Allarity Acquisition Subsidiary Inc. United States Allarity Therapeutics Europe ApS (formerly Oncology Venture Product Development ApS)* Denmark Allarity Therapeutics Denmark ApS (formerly OV-SPV2 ApS)* Denmark MPI Inc.* (1) United States * Wholly-owned subsidiary of Allarity Acquisition Subsidiary, Inc. (1) In the process of being dissolved because inactive. All intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation.
Use of Estimates and Assumptions	( b The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting years. Significant estimates and assumptions reflected in the Financial Statements include, but are not limited to, the fair value of the Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, warrants, convertible debt, convertible promissory note, and the accrual for research and development expenses, fair values of acquired intangible assets and impairment review of those assets, share based compensation expense, and income tax uncertainties and valuation allowances. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering reasonable changes in circumstances, facts, and experience. Changes in estimates are recorded in the period in which they become known and if material, their effects are disclosed in the notes to the financial statements. Actual results could differ from those estimates or assumptions.
Foreign currency and currency translation	(c) Foreign currency and currency translation The functional currency is the currency of the primary economic environment in which an entity’s operations are conducted. The Company and its subsidiaries operate mainly in Denmark and the United States. The functional currencies of the Company’s subsidiaries are their local currency. The Company’s reporting currency is the U.S. dollar. The Company translates the assets and liabilities of its Denmark subsidiaries into the U.S. dollar at the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at the average exchange rate in effect during each monthly period. Unrealized translation gains and losses are recorded as a cumulative translation adjustment, which is included in the condensed consolidated statements of changes in redeemable convertible preferred stock and stockholders’ equity (deficit) as a component of accumulated other comprehensive loss. Monetary assets and liabilities denominated in currencies other than the functional currency are remeasured into the functional currency at rates of exchange prevailing at the balance sheet dates. Non-monetary assets and liabilities denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing at the date of the transaction. Exchange gains or losses arising from foreign currency transactions are included in the determination of net loss for the respective periods. Adjustments that arise from exchange rate translations are included in other comprehensive loss in the condensed consolidated statements of operations and comprehensive loss as incurred. Adjustments that arise from exchange rate translations are included in other comprehensive loss in the consolidated statements of operations and comprehensive loss as incurred. The Company recorded a foreign exchange translation gain of $25 and $84, included in accumulated other comprehensive loss for the three month periods ended March 31, 2024 and 2023, respectively.
Concentrations of credit risk and of significant suppliers	(d) Concentrations of credit risk and of significant suppliers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company maintains its cash in financial institutions in amounts that could exceed government-insured limits. The Company does not believe it is subject to additional credit risks beyond those normally associated with commercial banking relationships. The Company has not experienced losses on its cash accounts and management believes, based upon the quality of the financial institutions, that the credit risk regarding these deposits is not significant. The Company is dependent on third-party manufacturers to supply products for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply its requirements for supplies and raw materials related to these programs. These programs could be adversely affected by a significant interruption in these manufacturing services or the availability of raw materials.
Cash	(e) Cash Cash consists primarily of highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents.
Accumulated other comprehensive loss	(f) Accumulated other comprehensive loss Accumulated other comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events other than those with shareholders. The Company records unrealized gains and losses related to foreign currency translation and instrument specific credit risk as components of other accumulated comprehensive loss in the condensed consolidated statements of operations and comprehensive loss. During the three months ended March 31, 2024, and 2023, the Company’s other comprehensive gain was comprised of currency translation adjustments.
Contingencies	(g) Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each reporting date, the Company evaluates whether a potential loss amount or a potential loss range is probable and reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The Company expenses costs as incurred in relation to such legal proceedings as general and administrative expense within the condensed consolidated statements of operations and comprehensive loss.
Reclassification	(h) Reclassification During the three months ended March 31, 2023, we have reclassified financing costs of $9 from other income and expenses to general and administrative expenses with no net impact upon our operating results or cash flows for either the current or prior periods.
Recently Issued Accounting Pronouncements	(i) Recently Issued Accounting Pronouncements Changes to U.S. GAAP are established by the FASB in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. All other ASUs issued through the date of the Financial Statements were assessed and determined not to be applicable or are expected to have minimal impact on the Company’s condensed consolidated financial position and results of operations.
