Phase 2 Study to Evaluate Brincidofovir for the Prevention of Adenovirus Disease

This was a Phase 2, randomized, multicenter, placebo-controlled study for pediatric and adult subjects who had undergone hematopoietic stem cell transplantation (HCT) and who had been identified as having asymptomatic adenovirus (AdV) viremia \[i.e., had detectable AdV DNA in plasma based on polymerase chain reaction testing performed at the local laboratory with no AdV disease symptoms\]. The primary objectives of the study were to assess the safety and tolerability of oral brincidofovir (BCV), and to estimate the treatment failure rate based on an efficacy endpoint with 2 different dosing regimens of oral BCV versus placebo.
