Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomised, Phase 2a, double-blind, placebo-controlled study to evaluate the safety, pharmacokinetics and antiviral activity of multiple doses of orally administered EDP-938 in healthy subjects infected with RSV-A Memphis 37b. This study is designed to compare the antiviral effect of EDP-938 compared to a placebo control in the respiratory syncytial virus challenge model.
