1730. Outcomes of Patients With Detectable Cytomegalovirus (CMV) DNA at Randomization in the Double-blind, Placebo-Controlled Phase 3 Trial of Letermovir (LET) Prophylaxis for CMV-Seropositive Allogeneic Hematopoietic-Cell Transplantation (HCT) Recipients

ABSTRACT: Abstract

Background

LET prophylaxis through HCT Week 14 was highly effective in preventing clinically significant CMV infection (CS-CMVi), had a good safety profile, and was associated with lower all-cause mortality by HCT Week 24 compared with placebo (PBO). Patients with detectable CMV DNA at randomization were excluded from the trial’s efficacy analyses (NCT02137772). Here we report the outcomes of these patients.

Methods

We compared patients randomized 2:1 and treated with LET or PBO who had detectable CMV DNA at randomization (n = 70) to those with undetectable CMV DNA (n = 495; primary efficacy population, PEP). CS-CMVi was defined as CMV viremia requiring antiviral preemptive therapy (PET) or CMV disease; patients with missing data were imputed as events. PET was p
