Description

Summary

The primary objective of this study is to evaluate the efficacy of letermovir (LET) versus valganciclovir (VGCV) in preventing CMV disease in adult kidney transplant recipients. The primary hypotheses are that LET is non-inferior to VGCV; and if non-inferiority is demonstrated, that LET is superior to VGCV, in preventing CMV disease through 52 weeks post-transplant.
