A Study of the Safety and Efficacy of CMX001 for the Prevention of CMV Infection in CMV-seropositive HCT Recipients

This was a randomized, double-blind, placebo-controlled, parallel group multicenter study of oral brincidofovir (BCV) in approximately 450 cytomegalovirus (CMV)-seropositive subjects who had undergone allogeneic hematopoietic stem cell transplantation (HCT). The study consisted of a screening evaluation and a treatment phase of 10 to 14 weeks. Dosing with the study drug (BCV or placebo) was initiated as soon as individual subjects could ingest tablets after transplant but no later than Day 28 post-transplant, and was continued through Week 14. All randomized subjects remained on study and followed the same scheduled study treatment. Study assessments were performed weekly from randomization through completion of the first post-treatment follow-up assessment at Week 15, and every 3 weeks thereafter through Week 24.
