Letermovir vs Valganciclovir in CMV R+ Kidney Transplant
Letermovir Versus Valganciclovir for 90 Days in CMV Seropositive Kidney Transplant Recipients: Results of a Single-center Experience.
The purpose of this study is to find out whether letermovir can help prevent cytomegalovirus (CMV) infection in kidney transplant recipients who are CMV seropositive. To do this, researchers will compare patients who received letermovir with a group of historical patients who received valganciclovir ("mini dose"). Both groups will be on CMV prophylaxis drug for 90 days post-transplant.
The main question the study wants to answer is:
• Does letermovir work as well as valganciclovir in preventing CMV infections during the first 12 months after a kidney transplant?
The study will also look at other important questions:
- Is letermovir easier for patients to tolerate than valganciclovir?
- How long does it take for a CMV infection to appear in each group?
- Are there differences in "breakthrough" CMV infections between the two medications?
- For patients who develop CMV that becomes resistant to treatment, are the resistance patterns different between the two groups

상세 설명
The purpose of this study is to evaluate the efficacy and tolerability of letermovir compared to standard-of-care, valganciclovir, for the prevention of clinically significant cytomegalovirus (CMV) infection in CMV moderate risk adult kidney transplant recipients.
A 3:1 match of historical valganciclvoir:letermovir arm
• Matching criteria:
- Induction agent: lymphocyte-depleting (rabbit anti-thymocyte globulin or alemtuzumab) versus non-lymphocyte depleting (basiliximab)
- Delayed graft function (dialysis within one week of kidney transplant)
- MMF dose at de novo discharge (weight-based vs non-weight based)
Study Arms:
Letermovir Arm:
- Letermovir 480 mg PO daily starting POD 4 through 10 OR
- Letermovir 240 mg PO daily if given concomitantly with cyclosporine, for 90 days
- Will be given with acyclovir 400 mg PO BID (or 200 PO BID if CrCl <25) for 90 days
Historical Arm:
Valganciclovir 450 mg PO daily (adjusted for renal function) for 90 days
- CrCl 25-30: valganciclovir 450 mg PO q 48 h
- CrCl <25: Valganciclovir 450 mg PO three times weekly
Outcomes:
Primary Efficacy Objective:
Incidence of patients with clinically significant CMV infection at 12 months post kidney transplant in patients who received letermovir versus standard of care valganciclovir
- Clinically Significant CMV Infection: CMV disease or symptomatic viremia requiring therapeutic intervention
Secondary Objectives:
Tolerability:
- Proportion of patients with leukopenia or neutropenia (composite) in patients who received letermovir versus standard of care valganciclovir
- Leukopenia: white blood cells < 3500 cells/uL
Neutropenia: absolute neutrophil count < 1000 cells/uL
- Intolerability or early drug discontinuation
Proportion of patients who discontinue the study drug prematurely due to adverse events or intolerance
o Efficacy:
- Time-to clinically significant CMV infection (days)
- Breakthrough CMV while on CMV prophylaxis
CMV Viremia
- Detection of CMV DNA in blood via PCR
Clinically significant CMV infection
- CMV resistance
- Detection of CMV strains with genotypic or phenotypic resistance to antiviral agents used in prophylaxis or treatment
