This study tests an experimental antiviral drug, S-337395, in adults with RSV who are not hospitalized but have health conditions that put them at high risk for severe illness. Participants receive either the drug or a placebo within 72 hours of symptoms starting. The main goal is to see if the drug reduces the amount of virus in the nose and throat over the first few days.
