Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort A: Partcipants who Received Valganciclovir

Participants with donor positive (D+)/recipient negative (R-) cytomegalovirus (CMV) serology, who receive valganciclovir prophylaxis according to the local prescribing information, will be observed for spermatogenesis up to 52 weeks post-transplant.

Group Type EXPERIMENTAL

Valganciclovir

Intervention Type DRUG

Participants will receive valganciclovir 900 milligrams (mg) orally once daily for up to a maximum of 200 days post-transplant.

Cohort B: Untreated Participants

Participants with donor negative (D-)/R- CMV serology, who do not receive prophylaxis, will be observed for spermatogenesis up to 52 weeks post-transplant.

Group Type NO_INTERVENTION
