A Phase 3 Randomized, Double-blind, Placebo-controlled Clinical Trial to Evaluate the Safety and Efficacy of Letermovir (LET) Prophylaxis When Extended From 100 Days to 200 Days Post-transplant in Cytomegalovirus (CMV) Seropositive Recipients (R+) of an Allogenic Hematopoietic Stem Cell Transplant (HSCT)

In Brief

A Phase 3 clinical trial evaluating Letermovir and Placebo for Cytomegalovirus Infection. Completed, enrolled 220 participants across 32 sites in 6 countries.

Detailed Summary

The purpose of this study was to evaluate the safety and efficacy of letermovir (LET) versus placebo when cytomegalovirus (CMV) prophylaxis was extended from 100 days to 200 days post-transplant in CMV seropositive participants who received an allogenic hematopoietic stem cell transplant (HSCT). It was hypothesized that LET is superior to placebo in the prevention of clinically-significant CMV infection when LET prophylaxis is extended from 100 to 200 days.
