A Study of the Safety and Efficacy of CMX001 for the Prevention of CMV Infection in CMV-seropositive HCT Recipients

Phase 3

Conditions
CMV
Interventions

Registration Number

Brief Summary

This randomized, double-blind, placebo-controlled, parallel group, multicenter study compared the effectiveness of oral brincidofovir (BCV) to placebo for the prevention of cytomegalovirus (CMV) infection in stem cell transplant patients who were CMV seropositive but negative for CMV viremia before starting treatment with BCV.

Detailed Description

This was a randomized, double-blind, placebo-controlled, parallel group multicenter study of oral brincidofovir (BCV) in approximately 450 cytomegalovirus (CMV)-seropositive subjects who had undergone allogeneic hematopoietic stem cell transplantation (HCT). The study consisted of a screening evaluation and a treatment phase of 10 to 14 weeks. Dosing with the study drug (BCV or placebo) was initiated as soon as individual subjects could ingest tablets after transplant but no later than Day 28 post-transplant, and was continued through Week 14. All randomized subjects remained on study and followed the same scheduled study treatment. Study assessments were performed weekly from randomization through completion of the first post-treatment follow-up assessment at Week 15, and every 3 weeks thereafter through Week 24.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Clinically Significant CMV Infection Through Week 24 Post-Transplant24 weeks

Clinically significant cytomegalovirus (CMV) infection was defined by either of the following outcomes:

1. Onset of CMV end-organ disease; or

2. Initiation of anti-CMV-specific preemptive therapy based on documented CMV viremia (as measured by the central virology laboratory) and the clinical condition of the subject.

CMV viremia (i.e., the measurement of CMV DNA in plasma) was determined by the designated central virology laboratory at all scheduled visits via quantitative polymerase chain reaction (qPCR) testing using the Roche COBAS® AmpliPrep/COBAS® TaqMan® CMV Test.

Secondary Outcome Measures
NameTimeMethod
Incidence of Clinically Significant CMV Infection Through Week 1414 weeks

The incidence of clinically significant cytomegalovirus (CMV) infection through Week 14.

Blood and urine for virologic evaluations were collected at screening, pre-dose on the first day of study drug administration, and at pre-specified intervals throughout the treatment phases of the study and sent to a designated central virology laboratory for analysis. Blood samples were used for real-time assay of CMV viremia in plasma using a qPCR assay. Urine samples were stored for possible future retrospective analyses of CMV.
