CINCINNATI, Nov. 10, 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 ARDS associated with COVID-19 infections, today reported financial results for the third quarter ended September 30, 2020 and provided a business update.

Recent Company Highlights

• On August 4^th, we announced a second randomized, double-blind Phase 2 clinical trial in patients with moderate-to-severe COVID-19 (“RESCUE” trial). The RESCUE trial is being supported by the U.S. Government operating through the Medical Technology Enterprise Consortium (MTEC). MTEC is a 501(c)3 non-profit organization constructed by the U.S. Army Medical Research and Development Command (USAMRDC). The RESCUE trial is a stand-alone trial managed by Aerpio designed to evaluate patients with moderate-to-severe COVID-19 prior to initiating high flow oxygen or ventilator support. Endpoints will include proportion of subjects alive and respiratory failure-free at Day 28; length of hospitalization from baseline to Day 7; and baseline to Day 28, or death. On October 26^th, Aerpio announced that it had dosed its first patient in this clinical trial. For more details about this clinical trial, please click here.
• On September 1^st, Aerpio and Quantum Leap Healthcare Initiative announced dosing of the first razuprotafib patient in the I-SPY COVID Trial (Investigation of Serial Studies to Predict Your COVID Therapeutic Response with biomarker Integration and Adaptive Learning) to evaluate razuprotafib for the treatment of COVID-19-related ARDS in adult patients with critical COVID-19 (requiring high flow oxygen or ventilator support). The I-SPY COVID Trial is a “platform study” currently planned to evaluate four drug candidates. The goal of the study is to identify agents with the potential to result in substantial improvements to the clinical condition of participants with critical COVID-19. The study is designed to include critical COVID-19 patients who are already intubated or receiving high flow oxygen. For more details about the I-SPY COVID Trial, please click here.
• On September 15^th, we announced that we have completed enrollment in the 28-day double-blind, placebo-controlled Phase 2 trial of razuprotafib in elevated intraocular pressure associated with open angle glaucoma (OAG) or ocular hypertension (OHT). The Phase 2 trial is evaluating adjunctive therapy of 40 mg /ml of razuprotafib, administered once, or twice-daily on top of a baseline of latanoprost ophthalmic solution 0.005%. The study enrolled a total of 194 patients.
• Our partner Gossamer Bio (Nasdaq: GOSS) indicated that it has initiated its Phase 2 trial of GB004 in ulcerative colitis (NCT04556383). GB004 is an oral, gut-targeted HIF-1 alpha stabilizer that has been shown to improve disease indices in multiple models of inflammatory bowel disease.  We out-licensed GB004 to Gossamer through an agreement under which we are eligible for up to a total of $90.0 million in milestone payments related to regulatory approvals and commercial sales. In addition, we are also eligible to receive tiered royalties on sales of licensed products at percentages ranging from the low to mid-single digits as well as 20% of proceeds from any transaction that Gossamer completes that includes the GB004 program.
• On November 12^th at 11 AM ET, we are hosting a Key Opinion Leader call with Samir Parikh, MD (Beth Israel Deaconess/Harvard Medical School) and Wesley Self, MD (Vanderbilt University) on new therapeutic agents in COVID-19 entitled “COVID-19: Evidence of Vascular Pathology and Potential of Vascular Stabilization via Tie2 Pathway Activation.” A link to the webcast can be found here.
  

“Enrollment in our Phase 2 glaucoma trial closed on time. We are now in the process of final database close activities and remain on track to report topline results from this study in December or possibly in early January 2021 to coincide with seasonal healthcare industry conferences.  In addition, we continue to make progress in both ARDS clinical trials of COVID-19 patients. The potential for razuprotafib to prevent ARDS in COVID-19 patients or rescue current ARDS patients from COVID’s devastating effects is very exciting. Assuming success in COVID-19 patients, we have the potential to expand the usage of razuprotafib into other life threatening diseases that produce a severe ARDS syndrome. We hope to provide an update from our COVID programs in the first half of 2021,” said Joseph Gardner, President and Founder.

Third Quarter 2020 Financial Highlights

As of September 30, 2020, cash and cash equivalents totaled $47.3 million, compared to $38.5 million as of December 31, 2019. Shares outstanding as of September 30, 2020 totaled approximately 47.1 million which includes the 6.5 million shares sold during the quarter ended September 30, 2020. Weighted average shares (basic) outstanding for the three and nine months ended September 30, 2020 were 42.1 million and 41.1 million, respectively.

For the three months ended September 30, 2020, operating expenses totaled $5.9 million, an increase of 18.0% compared to $5.0 million for the same period in 2019.

Research and development expenses for the three months ended September 30, 2020, increased approximately $1.1 million, or 40.1%, to $4.0 million from $2.9 million in the three months ended September 30, 2019. This increase was primarily the result of increased expenses associated with our clinical programs.

General and administrative expenses for the three months ended September 30, 2020, decreased approximately $0.3 million, or 13.2%, to $1.9 million from $2.2 million, in the three months ended September 30, 2019.

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.
