What this study is

Simplified from ClinicalTrials.gov

Testing a pill (zelicapavir) to treat RSV, a common respiratory virus that can cause serious lung illness, in non-hospitalized adults at high risk for severe disease: those 75 or older, or 18 or older with COPD or heart failure. Participants must have had RSV symptoms for up to 72 hours and test positive for RSV.

Read the original summary from ClinicalTrials.gov

Zelicapavir is a novel orally administered non-fusion replication inhibitor of RSV that is being developed for the treatment of patients with RSV infection. This phase 2b/3 study will evaluate the efficacy and safety of zelicapavir compared with placebo in adults with RSV who are at high risk for severe disease. High-risk participants include those who are either ≥75 years of age or ≥18 years of age with COPD and/or CHF. Participants will be non-hospitalized adults who have up to 72 hours of respiratory tract infection symptoms and test positive for RSV.
