Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature of Organization and Operations	1. Nature of Organization and Operations Aadi Bioscience, Inc. (together with its subsidiaries, the “Company” or “Aadi”) is a biopharmaceutical company focused on developing and commercializing precision therapies for genetically defined cancers with alterations in mTOR pathway genes. Aadi’s lead drug product, FYARRO^TM, nab-sirolimus, (sirolimus protein-bound particles for injectable suspension), is a form of sirolimus bound to albumin. Sirolimus is a potent inhibitor of the mTOR biological pathway, the activation of which pathway can promote tumor growth, and inhibits downstream signaling from mTOR. In November 2021, the U.S. Food and Drug Administration (the “FDA”) approved FYARRO sirolimus protein-bound particles for injectable suspension (albumin-bound) for intravenous use for the treatment of adult patients with locally advanced malignant perivascular epithelioid cell tumors (“PEComa”). On February 22, 2022, Aadi launched FYARRO in the United States for treatment of advanced malignant PEComa. FYARRO is licensed to Aadi by Abraxis BioScience, LLC, a wholly owned subsidiary of Celgene Corporation, now Bristol Myers Squibb Company (“Celgene”), for all therapeutic areas including oncology, cardiovascular, and metabolic related diseases. The Company’s historical operations have consisted principally of performing research and development activities and raising capital. The Company’s activities are subject to significant risks and uncertainties, including failing to secure additional funding before sustainable revenues and profit from operations are achieved. Merger with Aerpio Pharmaceuticals, Inc. and Name Change On May 16, 2021, the Company, then operating as Aerpio Pharmaceuticals, Inc. (“Aerpio”), entered into the Agreement and Plan of Merger (“Merger Agreement”) with Aspen Merger Subsidiary, Inc., a Delaware corporation and a direct, wholly owned subsidiary of Aerpio (“Merger Sub”) and Aadi Subsidiary, Inc. (formerly known as Aadi Bioscience, Inc. (“Private Aadi”)). Pursuant to the terms set forth in the Merger Agreement and effective August 26, 2021 (the “Effective Time”): (i) Merger Sub merged with and into Private Aadi, with Private Aadi surviving as a wholly owned subsidiary of Aerpio (the “Merger”), (ii) Aerpio changed its name to Aadi Bioscience, Inc. in connection with and immediately prior to the Effective Time, and (iii) Aerpio effected a 15:1 reverse stock split of the Aerpio common stock (“Reverse Stock Split”) immediately prior to the Effective Time. At the Effective Time, each share of Private Aadi common stock outstanding immediately prior to the Effective Time, including the shares of Private Aadi common stock issuable upon the conversion of all shares of preferred stock and convertible promissory notes immediately prior to the closing of the Merger, were converted into the right to receive shares of the Company’s common stock based on an exchange ratio of 0.3172 (the “Exchange Ratio”), after taking into account the Reverse Stock Split. Pursuant to the Merger Agreement, the Company assumed all of the outstanding and unexercised options to purchase shares of Private Aadi capital stock under the Private Aadi Amended and Restated 2014 Equity Incentive Plan (the “Private Aadi Plan”), and, in connection with the Merger, such options were converted into options to purchase shares of the Company’s common stock based on the Exchange Ratio. At the closing of the Merger at the Effective Time, the Company issued an aggregate of 5,776,660 shares of common stock to holders of Private Aadi common stock, including in respect of shares of Private Aadi common stock issued upon the conversion of all shares of preferred stock and convertible promissory notes outstanding immediately prior to the Effective Time. In connection with the Merger, the Company entered into a Contingent Value Rights Agreement (the “CVR Agreement”) with a legacy director of the Company, as Holder Representative (as defined in the CVR Agreement), and American Stock Transfer & Trust Company, LLC, as Rights Agent (as defined in the CVR Agreement), in accordance with the terms of the Merger Agreement. The CVR Agreement entitles each holder of Aerpio common stock as of immediately prior to the closing of the Merger (each, a “CVR Holder”) to receive one contingent value right (“CVR”) for each outstanding share of Company common stock held by such CVR Holder as of immediately prior to the closing of the Merger, each representing the right to receive certain net proceeds, if any, derived from the CVR completed during a CVR Payment Period, which means successive six-month periods, prior to the expiration of the CVR Term (as defined in the CVR Agreement), with any potential payment obligations continuing until the earlier of (a) the 20-year anniversary of the Effective Time and (b) the time at which the license agreement with Gossamer Bio, Inc., the underlying basis for the CVR, has expired or been terminated. Under the terms of the Merger Agreement, as related to the CVR, the Company is entitled to 10% of any proceeds paid from the underlying license agreement plus reimbursement of expenses. There can be no assurances that any proceeds will result therefrom. The Merger has been accounted for using the reverse asset acquisition method under U.S. generally accepted accounting principles (“GAAP”). For accounting purposes, Private Aadi is considered to have acquired the Company and the Merger has been accounted for as a reverse asset acquisition. The estimated fair value of total consideration given was $110.4 million based on 3,208,718 shares of common stock at $33.00 per share, after taking into account the Reverse Stock Split, outstanding immediately prior to the Effective time, plus Private Aadi’s transaction costs. Private Aadi is considered the accounting acquirer even though the Company issued the common stock in the Merger based on the terms of the Merger Agreement and other factors including: (i) following the Merger, the stockholders of Private Aadi collectively owned a substantial portion of the voting rights of the Company; (ii) three (3) of seven (7) members of the board of directors of the Company post-Merger were composed of directors designated by Private Aadi under the terms of the Merger Agreement, and one (1) member of the board of directors of the Company post-Merger was a director mutually designated by Private Aadi and Aerpio; (iii) existing members of Private Aadi’s management became the management of the Company post-Merger; (iv) the PIPE Investors (as defined below) consist of individuals and funds, and for purpose of this analysis, while they owned approximately 55.6% on a fully-diluted basis, as of immediately following the Merger (and after giving effect to the PIPE Financing, as defined below), no one individual or fund held more shares than the holders of Private Aadi collectively owned immediately following the Merger and they are not considered to be a single voting group; and (v) following the Merger, the Company is named “Aadi Bioscience, Inc.” and headquartered in Pacific Palisades, California, and all ongoing operations of the Company are those of Private Aadi. To determine the accounting for this transaction under GAAP, a company must assess whether an integrated set of assets and activities should be accounted for as an acquisition of a business or an asset acquisition. Upon closing of the Merger, substantially all of the fair value is concentrated in cash, working capital and a long-lived contract intangible asset. As such, the acquisition was treated as an asset acquisition. The net assets of Aerpio have been recorded at their relative fair value in the consolidated financial statements of the Company and the reported operating results prior to the Merger will be those of Private Aadi. Pursuant to the closing of the Merger, Private Aadi’s board of directors declared a 4% cumulative dividend on its preferred stock of $4.4 million which was paid at the Effective Time. PIPE Financing and Subscription Agreement On May 16, 2021, the Company entered into a subscription agreement (“Subscription Agreement”) with certain investors (the “PIPE Investors”), pursuant to which it agreed to sell shares of its common stock concurrently with the closing of the Merger (the “PIPE Financing”). At the closing of the PIPE Financing, the Company entered into a Registration Rights Agreement, dated August 26, 2021 (“Registration Rights Agreement”), with the PIPE Investors. The PIPE Investors purchased an aggregate of 11,852,862 shares of common stock of the Company (the “PIPE Shares”) for an aggregate purchase price of $155.0 million pursuant to the Subscription Agreement (“PIPE Financing”). The aggregate net proceeds for the issuance and sale of the of the PIPE Shares was $145.4 million, after deducting certain expenses incurred that were direct and incremental to the issuance of the PIPE Shares. Immediately following the Effective Time, and after giving effect to the Reverse Stock Split and the PIPE Financing, there were approximately 20.8 million shares of common stock of the Company outstanding. Immediately following the Effective Time and after giving effect to the Reverse Stock Split and the PIPE Financing: (i) the Private Aadi stockholders owned approximately 29.2% of the outstanding shares of common stock; (ii) Aerpio’s stockholders immediately prior to the Merger, whose shares of common stock, as adjusted for the Reverse Stock Split, remain outstanding after the Merger, owned approximately 15.2% of the outstanding shares of common stock; and (iii) the PIPE Investors owned approximately 55.6% of the outstanding shares of common stock, in each case as calculated on a fully-diluted basis. Liquidity Since inception, the Company has devoted substantially all of its resources to research and development activities, business planning, establishing and maintaining its intellectual property portfolio, hiring personnel, raising capital and providing general and administrative support for these operations and has only recently begun to realize revenues from its planned principal operations commencing with the commercial sale of FYARRO. On March 17, 2022, the Company entered into a Sales Agreement (the “Sales Agreement”) with Cowen and Company, LLC (“Cowen”), pursuant to which the Company may offer and sell, from time to time at the Company’s sole discretion, shares of its common stock having an aggregate offering prices of up to $75.0 million through Cowen as its sales agent. As of March 31, 2022, no shares of common stock had been sold under this Sales Agreement. The Company has experienced net losses since its inception and expects to continue to incur net losses into the foreseeable future. The Company had an accumulated deficit of $156.5 million as of March 31, 2022 and a net loss of $13.9 million for the three months ended March 31, 2022. To date, these operating losses have been funded primarily from outside sources of invested capital through the issuance of convertible promissory notes, grant funding, the sale of securities, and proceeds from license agreements. The Company had cash and cash equivalents of $129.8 million at March 31, 2022. Management believes the Company’s current cash and cash equivalents will provide sufficient funds to enable the Company to meet its obligations for at least twelve months from the filing date of this report. COVID-19 In December 2019, a strain of coronavirus was reported in Wuhan, China and began to spread globally, including to the United States and Europe, in the following months. The World Health Organization has declared COVID-19 to be a global pandemic. The full impact of the COVID-19 pandemic is inherently uncertain at the time of this report. The COVID-19 pandemic has resulted in travel restrictions and, in some cases, prohibitions of non-essential activities, disruption and shutdown of businesses, and greater uncertainty in global financial markets. As COVID-19 has spread, it has significantly impacted the health and economic environment around the world. Aadi’s clinical trials have been, and may continue to be, affected by the closure of offices, or country borders, among other measures being put in place around the world. Restrictions on the ability to travel and conduct face-to-face meetings, as well as constraints surrounding hospital resources, infrastructure, staff and other resources, can also make it more difficult to enroll new patients in ongoing or planned clinical trials. Any of these circumstances will potentially have a negative impact on the Company’s financial results and the timing of its clinical trials. The COVID-19 pandemic has caused the Company to modify business practices (including but not limited to curtailing or modifying employee travel and participation in meetings, events and conferences, and curtailing or modifying its clinical trials), and may take further actions as may be required by government authorities or that are determined to be in the best interests of the Company’s employees, patients, and business partners. The extent of the impact of the COVID-19 pandemic on Aadi’s future liquidity and operational performance will depend on certain developments, including the duration and spread of further outbreaks, the availability, acceptance and effectiveness of vaccines, the impact on the Company’s clinical trials, patients, and collaboration partners, and the effect on its suppliers.
