Aerpio Pharmaceuticals Announces Review of Strategic Alternatives

Aerpio Pharmaceuticals, Inc. (NasdaqCM: ARPO), a biopharmaceutical company focused on developing compounds that activate Tie2 to treat ocular disease and diabetic complications, today announced that its Board of Directors has initiated a process to explore and review a range of strategic alternatives focused on maximizing stockholder value from the Company’s clinical assets and cash resources, which amounted to $48.2 million as of June 30, 2019. The Board is exploring the potential for an acquisition, company sale, merger, business combination, asset sale, in-license, out-license or other strategic transaction.

In addition, Aerpio has engaged Evercore, Ladenburg Thalmann & Co. Inc. and Duane Nash, M.D., J.D., M.B.A. to act as strategic advisors for this process. There can be no assurance that this exploration of strategic alternatives will result in the Company entering or completing any transaction. Aerpio does not intend to make any further disclosures regarding the strategic review process unless and until a specific course of action is approved.

In parallel with this strategic review, the Company also intends to streamline operations in order to preserve its capital and cash resources. Going forward, the management team will be led by Joseph Gardner, Ph.D., the Company’s current President with Gina Marek, the company’s Vice President of Finance, continuing in her position. Stephen J. Hoffman, M.D., Ph.D., and Michael W. Rogers, the company’s Chief Executive Officer and Chief Financial Officer, respectively, have transitioned from their roles, and Dr. Hoffman has resigned from his position on the Board.

About Aerpio Pharmaceuticals

Aerpio Pharmaceuticals, Inc. is a biopharmaceutical company focused on advancing first-in-class compounds that activate Tie2 to treat ocular diseases and complications of diabetes. Tie2 is an important regulator of vascular stability, and its down-regulation, through activation of two inhibitors VE-PTP and Ang-2, is found in patients with diabetes and other conditions. The Company’s lead compound, AKB-9778, a first-in-class small molecule inhibitor of VE-PTP, is being investigated in an ongoing Phase 1b clinical trial as a topical drop formulation for its therapeutic potential in open-angle glaucoma. In the recently completed phase 2b study (TIME-2b) AKB-9778 demonstrated the ability to lower proteinuria (as measured by decreasing urinary albumin creatine ratio, UACR) by about 20% replicating a finding in the previous phase 2 study. The decrease in proteinuria suggests that AKB-9778 and our other Tie2 activating drug, ARP-1536, may have the potential to improve kidney function in diabetics potentially delaying progression to kidney dialysis. The Company’s second asset, ARP-1536 is a humanized monoclonal antibody observed to activate Tie2 receptors in a dose-dependent manner in preclinical models. Aerpio believes ARP-1536 holds potential as a monthly or biweekly systemic therapy to treat diabetic complications, including diabetic nephropathy. The company’s third asset is a bispecific antibody that binds both VEGF and VE-PTP which inhibits VEGF activation and activates Tie2. This bispecific antibody has the potential to be an improved product for treating wAMD and DME via intravitreal injection. Finally, the Company has exclusively out-licensed its fourth asset AKB-4924 (now called GB004), a first-in-class small molecule inhibitor of hypoxia-inducible factor-1 (HIF). GB004 is being developed by AKB-4924’s exclusive licensor, Gossamer Bio, Inc. (Nasdaq: GOSS), in return for an upfront payment of $20 million, future potential development, regulatory, and sales milestones of up to $400 million, and royalties on worldwide net sales.
