Study Summary

This phase III single arm trial determines whether taking prophylactic letermovir will reduce the likelihood of infection with cytomegalovirus (CMV) in children and adolescents after stem cell transplant compared to estimated rate of infection without prophylaxis. The treatments used to prepare for HCT reduce the body's natural infection-fighting ability and increase the likelihood of an infection with a virus called cytomegalovirus. "Prophylaxis" means to take a drug to prevent a disease or side effect. Letermovir is an antiviral drug that stops cytomegalovirus from multiplying and may prevent cytomegalovirus infection and make the disease less severe.

Primary Outcome

Clinically significant CMV is defined as the first of (1) initiation of anti-CMV preemptive therapy for documented CMV DNAemia or (2) onset of CMV end-organ disease. Will estimate the cumulative incidence of clinically significant CMV at 14-weeks post-transplant and will report the corresponding 95% confidence interval.
