Valganciclovir to Prevent Cytomegalovirus Infection in Patients Following Donor Stem Cell Transplantation

A Phase III Multicenter Study Of Valganciclovir For The Prevention Of Late Cytomegalovirus Infection After Allogeneic Hematopoietic Stem Cell Transplantation

RATIONALE: Antivirals such as valganciclovir act against viruses and may be effective in preventing cytomegalovirus. It is not yet known if valganciclovir is effective in preventing cytomegalovirus.

PURPOSE: This randomized phase III trial is studying valganciclovir to see how well it works in preventing cytomegalovirus in patients who have undergone donor stem cell transplantation.

Study Overview

• Status: Completed
• Conditions: Infection
• Intervention / Treatment: Drug: valganciclovir; Drug: ganciclovir

Detailed Description

OBJECTIVES:

Primary

• Compare cytomegalovirus (CMV) disease and non-CMV invasive infection-free survival in patients undergoing allogeneic hematopoietic stem cell transplantation treated with valganciclovir vs placebo.
• Compare the incidence of CMV disease in patients treated with these drugs.
• Compare the incidence of other severe invasive bacterial and fungal infections and overall survival in patients treated with these drugs.

Secondary

• Compare the incidence of CMV infection or disease at baseline and at days 270 and 640 after allogeneic hematopoietic stem cell transplantation in patients treated with these drugs.
• Compare the incidence of herpes simplex virus and varicella-zoster virus infections at baseline and day 270 in patients treated with these drugs.
• Determine the safety of valganciclovir in these patients.
• Compare the quality of life of patients treated with these drugs.
• Compare CMV-specific immune reconstitution in patients treated with these drugs.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to participating center, prior neutropenia (yes vs no), and presence of refractory graft-versus-host disease requiring secondary therapy (yes vs no). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral valganciclovir daily.
• Arm II: Patients receive oral placebo daily. Treatment begins around day 80-120 post-transplantation and continues until day 270 post-transplantation in the absence of active infection or unacceptable toxicity. Patients developing active cytomegalovirus (CMV) infection receive induction doses of ganciclovir IV or open-label oral valganciclovir for 1 week followed by open-label oral valganciclovir maintenance dosing until CMV can no longer be detected.

Quality of life is assessed at baseline and days 180 and 270 post-transplantation.

Patients are followed at days 400, 520, and 640 post-transplantation.

PROJECTED ACCRUAL: A total of 184 patients (92 per treatment arm) will be accrued for this study.
