Enanta in Phase 1 Clinical Study of Protease Inhibitor for Treatment and Prevention of COVID-19

 -Enanta Pharmaceuticals, Inc. (NASDAQ:ENTA), a clinical-stage biotechnology company dedicated to creating small molecule drugs for viral infections and liver diseases, today announced that it has dosed the first subject in its Phase 1 clinical trial of EDP-235, a coronavirus 3CL protease inhibitor (also known as the main coronavirus protease, or Mpro) specifically designed as a once-daily, oral treatment for COVID-19.

"SARS-CoV-2 continues to infect millions of individuals worldwide and new variants are still emerging, highlighting the limitations of current therapies and vaccines for COVID-19. There remains an urgent need for highly potent, oral treatments designed specifically to treat and prevent COVID-19, and we believe that the profile of EDP-235 positions it to potentially be a best-in-class antiviral therapeutic," said Jay R. Luly Ph.D., President and Chief Executive Officer of Enanta Pharmaceuticals. "We are excited to reach this milestone and begin our EDP-235 clinical program, with the first subject being dosed in this Phase 1 study. Looking to the rest of the year, we plan to report data from this study in the second quarter of 2022 and, assuming positive findings, we expect to advance EDP-235 to the next stage of clinical development in the second half of 2022."

This first-in-human Phase 1 study will evaluate the safety, tolerability, and pharmacokinetics of oral EDP-235 in single ascending doses (SAD), including a two-part food effect cohort, and multiple ascending doses (MAD) compared to placebo in healthy volunteers. All SAD and MAD cohorts will enroll eight participants who will be randomized to receive EDP-235 or placebo in a 3:1 ratio.
