• Subsequent to March 31, 2021, Aerpio entered into an agreement and plan of merger with Aadi Bioscience, Inc.

CINCINNATI, May 17, 2021 (GLOBE NEWSWIRE) -- Aerpio Pharmaceuticals, Inc. (“Aerpio”) (Nasdaq: ARPO), a biopharmaceutical company focused on developing compounds that activate Tie2, today reported financial results for the first quarter ended March 31, 2021 and provided a business update.

Key Business Update:

• On May 16, 2021, Aerpio entered into an agreement and plan of merger with Aadi Bioscience, Inc., a Delaware company (“Aadi"), and Aspen Merger Subsidiary, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of Aerpio (“Merger Sub”), wherby Merger Sub will merge with and into Aadi with Aadi surviving as a wholly-owned subsidiary of Aerpio. The proposed merger was approved by the members of the board of directors of Aerpio (the “Board”) and the Board resolved to recommend approval of the proposed merger agreement to Aerpio’s shareholders. The closing of the proposed Aadi merger is subject to approval of the Aerpio shareholders and the satisfaction of certain closing conditions, including approval by Aerpio’s shareholders, the completion of the PIPE financing described below and other customary closing conditions.
• Following the proposed merger, Aerpio will change its name to “Aadi Bioscience Inc.” and the combined public company will focus on advancing Aadi’s lead product candidate, FYARRO^TM (sirolimus albumin-bound nanoparticles for injectable suspension; nab-sirolimus; ABI-009).
• In connection with the execution of the proposed merger with Aadi, Aerpio entered into subscription agreements to raise an aggregate of $155 million in a Private Investment in Public Equity (“PIPE”) financing in shares of common stock and pre-funded warrants to purchase Aerpio common stock. The financing is expected to be consummated concurrently with the closing of the proposed merger, subject to customary closing conditions, and is contingent on the closing of the proposed merger.
• If Aerpio is unable to satisfy the closing conditions in Aadi’s favor or if other applicable closing conditions are not satisfied, Aadi will not be obligated to complete the proposed merger. Under certain circumstances, Aerpio would be required to pay Aadi a termination fee of $2 million.
• The terms of the merger agreement contemplate that a non-transferable contingent value right (a “CVR”) will be distributed to Aerpio shareholders as of immediately prior to the effective time of the proposed merger, entitling CVR holders to receive net proceeds received by Aerpio, if any, associated with Aerpio’s legacy assets. The terms and conditions of the CVRs will be pursuant to a CVR Agreement Aerpio will enter into prior to the closing of the proposed merger.
  

Recent Company Events

• In February 2021, Aerpio discontinued its RESCUE trial for the prevention and treatment of acute respiratory distress syndrome (“ARDS”) in adult patients with moderate to severe COVID-19 sponsored by the Medical Technology Enterprise Organization (“MTEC”) after the first 31 patients based on challenges associated with recruiting and monitoring patients in the current pandemic environment. Based on topline data, there were no apparent safety signals associated with dosing COVID-19 patients with razuprotafib. There was a mechanism-based, dose-dependent reduction of blood pressure which was not associated with other adverse events. There was an apparent dose-dependent decrease in Angiopoeitin 2 (Ang2) that would be consistent with the Tie2 activation mechanism. The efficacy of razuprotafib could not be fully assessed due to the limited number of patients treated in the drug and standard of care arms. At the 28 day study endpoint, there were an equal number of deaths in each group (one per group). Further analysis of the full data set is ongoing.
