Brief Summary: The purpose of the study is to learn about the safety, pharmacokinetics and antiviral activity of the study medicine (called sisunatovir/RV521) for the potential treatment of respiratory syncytial virus (RSV). Sisunatovir will be given as multiple doses during the treatment period. RSV is a highly contagious virus that can lead to serious lung infections in patients with reduced ability to fight infection. Most vulnerable populations include babies, the elderly and patients that have received a bone marrow transplant.

This study is seeking healthy participants who are:

1. Aged 18 to 45 years old and will agree to the use of highly effective methods of contraception.
2. with a body mass index (BMI) of 18.0 to 30.0 Kg/m2 This study will consist of 2 cohorts of 33 participants each. In both cohorts participants will be exposed to the challenge virus on study day 0. Cohort 1 will receive either 200 mg of sisunatovir or placebo (looks the same as sisunatovir but contains no active medicine) 2 times a day for 5 days. Cohort 2 will receive either 350 mg of sisunatovir or placebo 2 times a day for 5 days. Participants will start taking the study medicine upon confirmation of RSV infection (or evening of Day 5 if not positive to RSV). The study medicine will be administered 12 hours apart (or twice daily). Each participant will remain in the quarantine unit until discharge on Day 12.
