Valganciclovir vs. Letermovir for CMV Prophylaxis in Heart Transplant

Overview

The purpose of this study is to compare the safety and efficacy of letermovir with valganciclovir for prevention of Cytomegalovirus (CMV) viremia in moderate to high risk serostatus heart transplant recipients.

This trial is a multi-center prospective, two-arm randomized study designed to assess the safety of letermovir use as the primary prophylaxis for CMV in patients recently transplanted with a heart. Although there are findings to support the safety and efficacy profiles of letermovir in certain patient populations (kidney transplant, lung transplant, and hematopoetic stem cell transplant), there is a clear lack of prospective data to support use of letermovir at the primary prevention of CMV for patients recently transplanted with a heart. Thus, despite numerous studies showing letermovir to be non-inferior to valganciclovir with a substantial reduction in leukopenia and neutropenia, valganciclovir continues to be the initial CMV prophylaxis in heart transplant recipients. This study aims to either confirm the findings about letermovir as seen in other patient populations, or to highlight potential concerns about using letermovir in heart transplant patients. Patients who get letermovir will also be given acyclovir for HSV (Herpes Simplex Virus) prophylaxis for 6 months. Those taking valganciclovir will not need this as HSV is covered by valganciclovir. Low risk patients will also be monitored during this period for a better understanding of CMV disease in this population.
