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

Prophylaxis Versus Preemptive Therapy for the Prevention of CMV in High-Risk R-D+ Liver Transplant Recipients

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.

详细说明

This is a prospective, randomized, multicenter trial of preemptive therapy vs. prophylaxis for prevention of Cytomegalovirus (CMV) disease in seronegative recipient- seropositive donor (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 for 100 days post-randomization with initiation of oral valganciclovir 900mg orally twice daily at onset of CMV viremia (monitored weekly) and continued until plasma PCR is negative on two consecutive weekly PCR tests. Study participants will be followed during the intervention period (100 days post randomization) and until 12 months post-transplant for CMV disease, toxicity, and clinical outcomes (opportunistic infections, rejection, graft loss and mortality). Drug safety labs will be assessed and recorded for the entire treatment period in both the prophylaxis and preemptive group. Re-transplantation and all-cause mortality will also be assessed at study closure and no longer than 5 years after enrollment. Additionally, the impact of the two CMV prevention strategies on CMV-specific cellular and humoral immune responses will be evaluated at 100 days after randomization, and 6 and 12 months post-transplant. A minimum of 176 subjects will be enrolled in the study. Allowing for over-enrollment to replace dropouts, up to 205 subjects may be enrolled to achieve the target enrollment of 176. Subjects will be randomized into one of the two groups in 1:1 ratio. 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. The secondary objectives are:1) to assess the two preventive strategies for clinical outcomes (major bacterial, fungal and non-CMV viral infections, rejection, graft loss and mortality) at one year post transplantation; 2) to assess the two preventive strategies for hematologic toxicity (assessment of neutropenia and receipt of hematopoietic growth factor during study days 1-107).
