Study Summary

This trial will compare the rates of CMV infection and disease in 30 heart transplant patients who will be given letermovir as prophylaxis to a retrospective cohort of 374 heart transplant patients. The tolerability of letermovir will also be assessed.

Who is the study for?
This trial is for adults aged 18-70 who have recently received a heart transplant and are at risk for cytomegalovirus, but not HIV positive or on dialysis. They mustn't be allergic to letermovir, participating in other clinical trials with investigational drugs, or planning to donate eggs/sperm within 90 days after the study.Check my eligibility
What is being tested?
The trial tests Letermovir as a preventive measure against CMV infection in heart transplant recipients. It compares outcomes of a new group of 30 patients with those from a past group of 374 patients, focusing on rates of neutropenia and drug tolerability.See study design
What are the potential side effects?
While specific side effects aren't listed here, typically antiviral medications like Letermovir could cause symptoms such as headache, nausea, vomiting, diarrhea; potential blood issues like neutropenia; and possibly allergic reactions.
