The Study is Being Done to See if Taking the Drug Valganciclovir Can Prevent CMV Infection.

Phase 3

Completed

• Conditions: Bone Marrow Stem Cell Transplant

• Registration Number: NCT00275665
• Lead Sponsor: Mayo Clinic

Brief Summary

This study is being done in stem cell transplant recipients to see if taking the drug valganciclovir can prevent or reduce serious cytomegalovirus (CMV) infections that can occur 100 days or later after transplant.

Detailed Description

This study is a phase III, randomized, double-blind, palacebo-controlled, multicenter study of the drug valganciclovir. This study is to see if taking prophylactic doses of valganciclovir starting 100 days after stem cell transplantation can prevent late CMV from occurring.

Participants will be randomized (like a flip of a coin) into one of two groups. Neither the participant nor the doctor will know which group the participant is in. One group will receive the drug valganciclovir. The other group will receive a pill that looks like valganciclovir, but does not contain any active medicine (a placebo).

Participants enrolled in the study will take the drug by mouth daily starting at day 100 post stem cell transplant. Participants will also have blood samples taken along with their routine blood weekly, until day 270. Participants will also be required to return to their routine clinic visits.

Participants' acquiring an active CMV bloodstream infection at the time of the study will receive ganciclovir by the vein twice a day or a high dose of valganciclovir. Participants will be instructed to stop taking the study drug during the treatment time. After active CMV infection can no longer be detected, the treatment will be stopped. Patients will start taking the study drug and will be monitored for a CMV bloodstream infection until 270 days after transplant. Participants developing symptoms that look like CMV disease (pneumonia, infection of the intestines, eye infection) while on the study drug, will have an examination and lab tests to diagnose the organism. Participants that are hospitalized for CMV disease or for any other reason are asked to notify study personnel.

Participants will need to record study medicine taken in a daily study drug diary. Questionnaires will be filled out by the participant throughout the study, they will also be called monthly to see how they are doing and feeling overall.

After 270 days, participants will complete the study drug phrase. They will receive follow up phone calls on days 400, 520, and 640 days after transplant to see how they are doing.
