About This Trial

This randomized, open-label, parallel group, two-arm, multi-center assessment will compare IV BCV with IV CDV in adult and pediatric allogeneic HCT recipients with AdV viremia. A virologic response-driven approach to duration of treatment will be evaluated, in which randomized subjects are treated with either BCV or CDV until AdV viremia is confirmed as undetectable or until a maximum of 12 weeks of therapy, whichever occurs first. All subjects will be followed for a total of 24 weeks post-randomization, regardless of treatment assignment. Subjects will be assessed on a weekly basis through the end of treatment visit (EOT). Additional assessments will be performed at the test of cure (TOC) visit, which is 4 weeks after the last dose of study drug and at Weeks 12 and 24 post W1D1.
