CMV Antiviral Prevention Strategies in D+R-Liver Transplants ("CAPSIL")

Summary

This is a trial of preemptive therapy vs. prophylaxis for prevention of Cytomegalovirus (CMV) disease in R-D+ liver transplant patients. Subjects 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 or preemptive therapy (weekly monitoring for CMV viremia by plasma PCR) for 100 days post-randomization with initiation of oral valganciclovir 900mg orally twice daily at onset of CMV viremia and continued until plasma PCR is negative on two consecutive weekly PCR tests). A minimum of 176 subjects will be enrolled in the study. The study duration is 7 years. The primary objective of this study is to compare prophylaxis versus preemptive therapy using valganciclovir for the prevention of CMV disease in R-/D+ liver transplant recipients.
