Study Summary

This is a phase 2 double-blind, randomized study of PBI-0451 in nonhospitalized symptomatic adults with COVID-19. PBI-0451 is a new chemical entity and inhibitor of the main protease of coronaviruses, including the SARS-CoV-2 that causes COVID-19 disease. This study is designed to evaluate the antiviral activity, safety, and efficacy of orally administered PBI-0451 compared with placebo.
