Clinical Trial Summary

RV521 is to being developed to treat RSV infection and disease in susceptible individuals at high risk for complications. This is an international, multicenter, placebo-controlled study. Eligible subjects are adults with a documented symptomatic RSV infection who have undergone HCT transplantation and are moderately to severely immunocompromised. Qualified subjects will be randomized in a 1:1 ratio to receive RV521 or placebo, twice daily for 10 days.


Clinical Trial Description

The purpose of this study is to compare the viral load, safety, tolerability, and clinical efficacy of RV521 compared to placebo. This is a Phase 2, international, multicenter, randomized, double-blind, placebo-controlled study. Up to 200 adult subjects with a documented symptomatic RSV URTI who have undergone HCT within 1 year of randomization and who are moderately to severely immunocompromised will be randomized. Qualified subjects will be randomized in a 1:1 ratio to receive RV521 capsules or matching placebo twice daily for 10 days. After the completion of the 10-day double-blind treatment period, subjects will be followed for an additional 28 days. Study drug may be taken on an outpatient or inpatient basis, depending on clinical status and site practices. Randomization will be stratified by type of HCT graft and ALC count. There are 9 clinic visits planned for this study. ;
