Letermovir Versus Valganciclovir to Prevent Human Cytomegalovirus Disease in Kidney Transplant Recipients (MK-8228-002)

Phase 3
Completed
Conditions
CMV Disease
Interventions
Drug: Placebo to ACV
Drug: Placebo to LET
Drug: Placebo to VGCV
Registration Number
NCT03443869
Lead Sponsor
Merck Sharp & Dohme LLC
Brief 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.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Adjudicated Cytomegalovirus (CMV) Disease Through 52 Weeks Post-transplantUp to 52 weeks

CMV disease was defined as the presence of either CMV end-organ disease or CMV syndrome and was confirmed by an independent, blinded Clinical Adjudication Committee (CAC). Only CAC-confirmed ("adjudicated") cases were included in percentage of participants who met the endpoint. Investigator-assessed cases which were not confirmed by the CAC were not included.

Secondary Outcome Measures
NameTimeMethod
Time to Onset of Adjudicated CMV Disease Through 52 Weeks Post-transplantUp to 52 weeks

The time to onset of adjudicated CMV disease was calculated in days, from the day of randomization to the day of onset of CMV disease as determined by the CAC.

Percentage of Participants With Adjudicated CMV Disease Through 28 Weeks Post-transplantUp to 28 weeks

CMV disease was defined as the presence of either CMV end-organ disease or CMV syndrome and was confirmed by an independent, blinded CAC. Only CAC-confirmed ("adjudicated") cases were included in percentage of participants who met the endpoint. Investigator-assessed cases which were not confirmed by the CAC were not included.

Percentage of Participants With Any AEUp to 52 weeks

An AE was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, was also an AE.

Percentage of Participants With Any Drug-related Serious Adverse Event (SAE)Up to 52 weeks

An SAE was an AE that resulted in death, was life threatening, resulted in persistent or significant disability/incapacity, resulted in or prolonged an existing inpatient hospitalization, was a congenital anomaly/birth defect, was a cancer, was associated with an overdose, was another important medical event. SAEs that the investigator determined the relationship of the AE to the treatment as at least possibly related were reported.
