About this study

Official title: Incidence of Cytomegalovirus Infection or Disease Using Valganciclovir Prophylaxis Versus Preemptive Therapy in Intermediate-Risk (R+) Living Donor Kidney Transplant Recipients Receiving Basiliximab-Based Immunosuppression: An Open-Label Clinical Trial (PREVAIL-KT)

Cytomegalovirus (CMV) infection remains one of the most frequent infectious complications after kidney transplantation. In intermediate-risk recipients (seropositive, R+ recipient) of living donor kidney transplants, optimal prevention strategies remain debated, particularly in the setting of basiliximab-based induction therapy.

This open-label clinical trial aims to compare the incidence of CMV infection or disease in intermediate-risk (R+) living donor kidney transplant recipients receiving valganciclovir prophylaxis versus a preemptive therapy strategy. All patients receive basiliximab-based immunosuppression as part of standard clinical practice.

Participants were enrolled between March 1, 2024 and July 31, 2025. Patients are followed for 12 months post-transplantation to assess the primary outcome of CMV infection or disease. Secondary outcomes include graft function, acute rejection episodes, and other infectious complications.

The results of this study may help define the optimal CMV prevention strategy in intermediate-risk living donor kidney transplant recipients under basiliximab-based immunosuppression.

Read the detailed description

Cytomegalovirus (CMV) infection remains one of the most frequent infectious complications after kidney transplantation and is associated with increased morbidity, acute rejection, and impaired graft survival. Recipients at intermediate CMV risk (seropositive recipients, R+) represent a large proportion of living-donor kidney transplant patients; however, the optimal prevention strategy in this population remains controversial.

Two main preventive approaches are currently used: universal antiviral prophylaxis and a preemptive therapy strategy based on viral load monitoring. While both strategies are accepted in clinical practice, comparative evidence in intermediate-risk living donor recipients receiving basiliximab induction therapy is limited, particularly in single-center settings in Mexico.

This single-center, open-label randomized controlled trial was conducted at the Transplant Division of UMAE Hospital de Especialidades, Centro Médico Nacional de Occidente (IMSS), Mexico. Adult recipients undergoing first living-donor kidney transplantation at intermediate CMV risk and receiving basiliximab induction were randomized to either a universal prophylaxis strategy with valganciclovir or a preemptive monitoring-based approach. All participants received standard maintenance immunosuppression and were followed for 12 months after transplantation.

The study aims to compare the effectiveness of these two prevention strategies in reducing CMV infection and disease, as well as evaluating associated hematologic adverse events and acute rejection episodes. The findings are expected to contribute evidence to guide CMV prevention strategies in intermediate-risk kidney transplant recipients in similar healthcare settings.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Valganciclovir ProphylaxisDrug

    Participants receive Valganciclovir 900 mg orally once daily for 3 months, starting on day 7 post-transplant. Standard maintenance immunosuppression with tacrolimus, mycophenolate mofetil, and prednisone is administered. Participants are followed for 12 months to assess CMV infection, CMV disease, hematologic adverse events, and acute rejection episodes

  • Preemptive Therapy (CMV PCR Monitoring)Diagnostic test

    Participants undergo quantitative CMV PCR monitoring every 15 days for the first 3 months and monthly until month 12. Antiviral therapy with Valganciclovir is initiated if viral load ≥1,000 copies/mL. Standard maintenance immunosuppression with tacrolimus, mycophenolate mofetil, and prednisone is administered. Participants are followed for 12 months to assess CMV infection, CMV disease, hematologic adverse events, and acute rejection episodes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of CMV infection and/or CMV disease

    CMV infection is defined as detectable CMV DNAemia by quantitative PCR. CMV disease is defined as CMV DNAemia plus compatible clinical syndrome (e.g., fever, malaise, cytopenias) and/or organ involvement (e.g., pneumonitis, colitis, pancreatitis)

    Measured: Within 12 months post-transplant

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 24 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of CMV infection and/or CMV disease (time frame: Within 12 months post-transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07430683, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2026.
