CINCINNATI — Nov. 7, 2018 — (BUSINESS WIRE) Aerpio Pharmaceuticals, Inc. (Nasdaq: ARPO), a biopharmaceutical company focused on developing compounds that activate Tie2 to treat ocular diseases and diabetic complications, today reported financial results for the third quarter ended September 30, 2018 and provided a business update.

“OurTIME-2b clinical trial, evaluating the effect ofAKB-9778, ourfirst-in-class systemically administered Tie2 activator in patients withnon-proliferative diabetic retinopathy (NPDR), is on track and we look forward to reportingtop-line results in early Q2 2019,” commented Stephen Hoffman, M.D., Ph.D., Chief Executive Officer of Aerpio. “In addition to the progress we’ve made withAKB-9778 for NPDR, we continue to advance a topical ocular formulation ofAKB-9778 in open angle glaucoma and expect to initiate a Phase 1b study in Q2 2019. We are also excited about the potential ofAKB-4924 (now known as GB004) and our partnership with Gossamer Bio, as announced in June. On the financial front, we remain well capitalized following the completion of a successful $52 million financing in June and receipt of the $20 million up front payment from our partnership with Gossamer.”

TIME-2b Study Overview

TheTIME-2b study is a double-masked, placebo-controlled, multi-center trial evaluating the effect ofAKB-9778 in patients with NPDR.167 patients were randomized to receive 48 weeks of treatment with eitherAKB-9778 15 mg subcutaneously once daily (and placebo subcutaneously once daily),AKB-9778 15 mg subcutaneously twice daily, or placebo subcutaneously twice daily. The primary endpoint of theTIME-2b study is the percentage of patients who improve by 2 or more steps in diabetic retinopathy severity score (DRSS) in the study eye. One of our secondary objectives, the urine albumin to creatinine ratio or UACR, was prospectively included based on apost-hoc analysis of this biomarker in theTIME-2 Phase 2a clinical trial ofAKB-9778 in diabetic macular edema. Initial results from this trial are expected early in the second quarter of 2019.

The Company’s lead compound,AKB-9778, is a systemically-administered small molecule activator of the Tie2 pathway (via highly selective and potent deactivation ofVE-PTP) and is in clinical development for the treatment ofnon-proliferative diabetic retinopathy.AKB-9778 is also being investigated for its potential utility in treating diabetic nephropathy and an eyedrop formulation is in development as a potential treatment for open-angle glaucoma.
