CINCINNATI, Jan. 05, 2021 (GLOBE NEWSWIRE) -- Aerpio Pharmaceuticals, Inc. (“Aerpio” or the “Company”) (Nasdaq: ARPO), a biopharmaceutical company focused on developing compounds that activate Tie2, 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 $47.3 million as of September 30, 2020.
As part of this process, the Company will explore strategic options for partnering its programs, as well as, the potential for an acquisition, company sale, merger, business combination, asset sale, in-license, out-license or other strategic transaction. Ladenburg Thalmann & Co. Inc. will continue to act as Aerpio’s financial advisor with respect to the strategic review process. There can be no assurance that this exploration of strategic alternatives will result in the Company entering or completing any transaction.
Aerpio programs to be incorporated into this review include:
- Phase 2 program of razuprotafib in glaucoma: a recently completed a Phase 2 trial in glaucoma patients showed that the change from baseline in diurnal mean IOP at Day 28 of study eyes treated with razuprotafib BID plus latanoprost was statistically significant (two-sided p-value 0.0130 and LS mean difference of -0.92 mmHg) compared to those treated with latanoprost monotherapy. Further analysis of the results demonstrated that razuprotafib had a larger IOP reduction after longer duration dosing (28 days versus 14 days) consistent with its potential mechanism of repairing Schlemm’s canal. Razuprotafib also produced larger IOP reductions in patients with higher starting IOP, or a 1.6 mmHg IOP reduction in patients with post wash-out IOP’s of >26 mmHg. The razuprotafib topical drops were well tolerated in this trial.
- Phase 2 program of razuprotafib in COVID-19: the Company has two ongoing clinical trials of razuprotafib to prevent or mitigate acute respiratory distress syndrome (ARDS) in COVID-19 patients where patient enrollment and dosing continues. If successful, these trials may open the door to treating ARDS across a broader array of infections.
- Preclinical Tie2 activating antibodies: the Company also has Tie2 activating antibodies in early development, including both a monospecific antibody that may be used to treat diabetic complications, and a bispecific antibody that may be used to treat retinal diseases such as diabetic macular edema (DME) and wet age related macular edema (wAMD).
Aerpio does not intend to make any further disclosures regarding the strategic review process unless and until specific actions are approved.
About Aerpio Pharmaceuticals
Aerpio Pharmaceuticals, Inc. is a biopharmaceutical company focused on developing compounds that activate Tie2 to treat ocular diseases and diabetic complications, as well as other indications in which the Company believes that activation of Tie2 may have therapeutic potential, including acute respiratory distress syndrome (“ARDS”) associated with COVID-19 infections. Recently published mouse and human genetic data implicate the Angpt/Tie2 pathway in maintenance of Schlemm’s canal, a critical component of the conventional outflow tract. The Company’s lead compound, razuprotafib (formerly AKB-9778), a first-in-class small molecule inhibitor of vascular endothelial protein tyrosine phosphatase (“VE-PTP”), is being developed as a potential treatment for open angle glaucoma, and the Company intends to investigate the therapeutic potential of razuprotafib in other indications. The Company is also evaluating development options for ARP-1536, a humanized monoclonal antibody, for its therapeutic potential in the treatment of diabetic vascular complications including nephropathy and diabetic macular edema (“DME”). The Company’s third asset is a bispecific antibody that binds both VEGF and VE-PTP which is designed to inhibit VEGF activation and activate Tie2. This bispecific antibody has the potential to be an improved treatment for wet age-related macular degeneration and DME via intravitreal injection. Finally, the Company has exclusively out-licensed 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. For more information, please visit www.aerpio.com.
About Razuprotafib (formerly known as AKB-9778)
Razuprotafib binds to and inhibits vascular endothelial protein tyrosine phosphatase (“VE-PTP”), an important negative regulator of Tie2. Decreased Tie2 activity contributes to vascular instability in many diseases including diabetes and more recently has been shown to contribute to the development of increased IOP and glaucoma. Razuprotafib activates the Tie2 receptor irrespective of extracellular levels of its binding ligands, angiopoietin-1 (agonist) or angiopoietin-2 (antagonist) and we believe that it may be the most efficient pharmacologic approach to maintain normal Tie2 activation. Aerpio is studying a topical ocular formulation of razuprotafib in open angle glaucoma and exploring the utility of subcutaneous razuprotafib for diabetic complications, including diabetic nephropathy. In addition, a subcutaneous formulation of razuprotafib is being explored for its therapeutic potential in treating or preventing ARDS associated with COVID-19.
