IMPACT Study: A Study of Valcyte (Valganciclovir) for Prevention of Cytomegalovirus Disease (CMV) in Kidney Allograft Recipients
A Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study of the Efficacy and Safety of up to 100 Days of Valganciclovir Versus up to 200 Days of Valganciclovir for Prevention of Cytomegalovirus (CMV) Disease in High-Risk Kidney Allograft Recipients
This study will determine the relative efficacy and safety of up to 100 days Valcyte prophylaxis relative to up to 200 days Valcyte prophylaxis when given for the prevention of CMV disease in high-risk (D+/R-) kidney allograft recipients. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
