Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older who have just received a heart transplant, are moderate-to-high CMV serostatus risk, and have not yet started CMV prophylaxis.
✕Probably not a fit
Patients with recent or suspected CMV disease within the prior six months, those who have already started CMV prophylaxis, or those at low CMV risk are unlikely to benefit from participation.

What this trial studies
This is a multicenter, prospective, randomized two-arm study comparing letermovir to valganciclovir as primary CMV prophylaxis in adult heart transplant recipients at moderate-to-high serostatus risk. Participants will be randomized to receive letermovir (with acyclovir for HSV prophylaxis for six months) or valganciclovir and will be followed for CMV viremia, CMV disease, and safety outcomes including leukopenia and neutropenia. Low-risk patients will be monitored observationally to better characterize CMV outcomes in that group. The trial is designed to confirm whether letermovir provides similar protection against CMV with a more favorable blood-count safety profile compared with valganciclovir in the heart transplant population.
Why it matters
Potential benefit: If successful, letermovir could prevent CMV viremia after heart transplant while reducing rates of leukopenia and neutropenia compared with valganciclovir.
How similar studies have gone: Previous studies in kidney, lung, and hematopoietic stem cell transplant populations have shown letermovir to be non-inferior to valganciclovir with substantially less leukopenia and neutropenia, but prospective data in heart transplant recipients are lacking.
