Could a safer drug replace standard antiviral for kidney transplant patients?
NCT ID NCT07294547
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if valacyclovir works as well as valganciclovir to prevent CMV and EBV infections in kidney transplant patients. Valganciclovir can cause bone marrow suppression, a serious side effect. The study will enroll 80 kidney transplant recipients and monitor them for new infections and side effects over time.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age at least 3 years of age * Patients who are about to receive or just received kidney transplantation within the past 2 weeks before the date of screening. * Will be receiving prophylactic antiviral therapy against CMV and/or EBV per discretion of transplant surgeon * No active CMV or EBV viremia (as defined by detectable viral load PCR) at the time of screening. * Ability and willingness of the patient (or parent/legal guardian for minors) to provide informed consent and comply with study procedures. Exclusion Criteria: * Severe co-morbidities that would preclude safe participation as judged by the transplant surgeon * Pregnancy (valganciclovir is likely teratogenic) * Known allergy to both valacyclovir and valganciclovir
