Aerpio Announces Initiation of Dosing in a Phase 1a, Multiple-Ascending Dose Study of AKB-4924, a Hypoxia-Inducible Factor-1 Alpha Stabilizer in Development for Inflammatory Bowel Disease

CINCINNATI--(BUSINESS WIRE)--May 22, 2018-- Aerpio Pharmaceuticals, Inc. (OTCQB:ARPO), today announced the initiation of dosing in a Phase 1a, multiple-ascending dose study of the Company’s hypoxia-inducible factor-1 alpha (HIF-1 alpha) stabilizer, AKB-4924.

AKB-4924 is a once-daily, oral, gut-restricted HIF-1 alpha stabilizer that has been shown to improve disease indices in multiple models of inflammatory bowel disease (IBD). “Unlike other HIF stabilizers that mainly affect HIF-2 and stimulate erythropoiesis, AKB-4924 is unique in that it preferentially stabilizes HIF-1 alpha, which has a profound anti-inflammatory and mucosal healing effect. These properties make it an ideal candidate for the treatment of IBD,” said Kevin Peters, MD, Aerpio’s Chief Scientific Officer.

The aim of the current study is to evaluate the safety and tolerability of multiple daily doses of AKB-4924 in healthy volunteers. The single-center pharmacokinetic and safety study is expected to enroll 24 subjects into 3 dose cohorts, randomized 3:1 to receive either AKB-4924 or placebo orally once daily for 8 days.
