Aerpio Announces Enrollment Completed in the 28-Day Phase 2 Razuprotafib Glaucoma Trial
Aerpio Pharmaceuticals (Nasdaq: ARPO) has completed patient enrollment for its Phase 2 trial examining the efficacy of razuprotafib for managing elevated intraocular pressure in glaucoma and ocular hypertension patients. This double-blind study involves around 195 participants over 28 days and tests razuprotafib against a latanoprost baseline. Results are expected in Q4 2020. The company believes razuprotafib could be a valuable adjunct therapy due to its novel action mechanism.
- Completed patient enrollment for Phase 2 trial on razuprotafib, indicating progress in research.
- Expected top line results in Q4 2020, which could influence stock performance positively.
- Dependence on trial outcomes; uncertain efficacy may lead to stock volatility.
- Potential market competition may impact future success and sales of razuprotafib.
CINCINNATI, Sept. 15, 2020 (GLOBE NEWSWIRE) -- Aerpio Pharmaceuticals, Inc.("Aerpio") (Nasdaq: ARPO), 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, today announced that it has completed patient enrollment in its double-blind, placebo-controlled Phase 2 trial in patients with elevated intraocular pressure (IOP) associated with open angle glaucoma (OAG) or ocular hypertension (OHT).
The study is designed to evaluate the safety and efficacy of a topical ocular formulation of razuprotafib in approximately 195 patients followed over a 28-day period, and patients must undergo a 28-day washout prior to randomization. Patients enrolled in the trial are administered a baseline of latanoprost ophthalmic solution
“We remain on track to report top line results from this trial in the fourth quarter,” said Kevin Peters, M.D., Chief Scientific Officer and Chief Medical Officer of Aerpio. “We believe that razuprotafib will represent an attractive adjunctive therapy for glaucoma patients based on its novel mechanism of action and favorable tolerability profile, and we have worldwide rights to the program.”
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. (Nasdaq: GOSS). 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 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.
