5. Study Description

Brief Summary
This phase 2 study is to assess the safety and tolerability of APX-115 active doses compared to placebo following multiple oral dosing in hospitalized patients with confirmed, mild to moderate, symptomatic COVID-19. It is anticipated that approximately 80 patients will be randomized into the study in a 1:1 ratio to 100 mg APX-115 or placebo arm.
Detailed Description
APX-115 is a potent small molecule inhibitor of NADPH-oxidase (Nox) isozymes being developed by Aptabio Therapeutics Inc. The Nox enzymes represent a family of 7 membrane enzymes (Nox1, Nox2, Nox3, Nox4, Nox5, Duox1, and Duox2) which catalyze NADPH-dependent generation of superoxide and secondary reactive oxygen species (ROS). ROS are often generated during virus infection, thus promoting apoptosis, lung injury, and inflammation/allergy.
