A Phase III, Randomized, Double-Blind, Active Comparator-Controlled Study to Evaluate the Efficacy and Safety of MK-8228 (Letermovir) Versus Valganciclovir for the Prevention of Human Cytomegalovirus (CMV) Disease in Adult Kidney Transplant Recipients

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.


Inclusion Criteria:

- Have a documented negative serostatus for CMV within 180 days prior to randomization.

- Anticipate receiving a primary or secondary allograft kidney from a CMV IgG
seropositive (D+) donor at the time of screening AND have received a primary or
secondary allograft kidney from a documented D+ donor at the time of randomization.

- Be within 0 (i.e. day of transplantation) to 7 days (inclusive) post-kidney transplant
at the time of randomization.

- Males agree to use contraception during the treatment period, and for at least 90 days
after the last dose of study treatment, and refrain from donating sperm during this
period.

- Female is not pregnant, not breastfeeding, and is not a woman of childbearing

the treatment period and for at least 90 days after the last dose of study treatment.

Exclusion Criteria:

- Has received a previous solid organ transplant or hematopoietic stem cell transplant
(HSCT). Note: Participants who have received a prior primary allograft kidney may be
enrolled, provided that all other inclusion/exclusion criteria are met.

- Is a multi-organ transplant recipient (e.g. kidney-pancreas). Double kidney transplant
recipients (i.e. transplant of two kidneys from the same donor to the same recipient
simultaneously) will be excluded.

randomization.

screening.

- Has any uncontrolled infection on the day of randomization.

- Has documented positive results for human immunodeficiency virus antibody (HIV-Ab)
test at any time prior to randomization, or for hepatitis C virus antibody (HCV-Ab)
