Study of Obeldesivir to Treat Nonhospitalized Adults With Acute Respiratory Syncytial Virus (RSV) Infection

Purpose

The goal of this clinical study is to learn more about the study drug, obeldesivir (ODV; GS-5245), and how safe and effective it is in treating nonhospitalized adults with acute respiratory syncytial virus (RSV) infection. The researchers want to see if obeldesivir can help participants' symptoms get better faster. The primary objectives of this study are to evaluate the efficacy of ODV in reducing the duration of symptoms and to evaluate the safety and tolerability of ODV in nonhospitalized adult participants with acute RSV infection.
