Letermovir Prophylaxis for CMV in Transplant Patients

This study is looking at a new way to use letermovir, a medicine that helps prevent cytomegalovirus (CMV) infections, in people who have had a hematopoietic cell transplant (HCT). The goal is to see if adjusting when you take letermovir, based on how your immune system responds to CMV, can better prevent infections compared to taking it continuously. You might be able to join if you've had an allogeneic HCT (transplant from a donor), have tested positive for CMV in the past, and are currently taking letermovir. The study will measure safety and side effects over about one year. The study is currently recruiting 105 participants.

Study design
This interventional study plans to enroll 105 participants. It compares two approaches to taking letermovir after a hematopoietic cell transplant.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for safety and adverse events through study completion, which is an average of one year.
