Prophylaxis Versus Preemptive Therapy for the Prevention of CMV in Liver Transplant Recipients


About this study

This is a study of two different approaches for the prevention of CMV disease in liver transplant recipients. The primary purpose is to determine if Preemptive therapy is the same or better than Prophylaxis therapy for the prevention of CMV disease in CMV seronegative recipients that receive a CMV positive liver transplant. Patients meeting study criteria and who have provided informed consent will be randomized within 10 days of transplant to receive in an open label design, either antiviral prophylaxis with valganciclovir 900 mg orally once daily for 100 days or preemptive therapy (weekly monitoring for asymptomatic CMV viremia by plasma PCR) for 100 days with initiation of oral valganciclovir 900mg orally twice daily only at onset of CMV viremia and continued until plasma PCR is negative on two consecutive weekly PCR tests.
