Prophylactic Use of Maribavir for the Prevention of Cytomegalovirus (CMV) Disease in Stem Cell Transplant Recipients

Phase 3
Completed
Conditions
Cytomegalovirus Infections
Interventions
Other: placebo
Registration Number
NCT00411645
Lead Sponsor
Shire
Brief Summary

The purpose of this research study is to investigate whether or not maribavir is safe and effective for preventing CMV disease when taken by mouth for up to 12 weeks in patients who have had a stem cell transplant.

Detailed Description

Cytomegalovirus (CMV) infections remain a significant problem following various types of transplants that are associated with strong immunosuppressive therapy. Maribavir is a new oral anti-CMV drug with a novel mechanism of action compared to currently available anti-CMV drugs. This study will test the safety and efficacy of maribavir for the prevention of CMV disease when given as prophylaxis for up to 12 weeks following allogeneic stem cell transplant.

Primary Outcome Measures
NameTimeMethod
Number of Participants With Endpoint Committee (EC)-Confirmed Cytomegalovirus (CMV) Disease Within 6 Months Post-Transplantation6 months post-transplant

All investigator-determined cases of CMV disease (i.e., CMV infection or CMV organ disease), were adjudicated by an independent, blinded EC. CMV infection was assessed by (1) pp65 antigenemia assay; (2) CMV DNA polymerase chain reaction (PCR); (3) either assay (pp65 antigenemia or CMV DNA PCR); or (4) initiation of anti-CMV therapy. CMV infection was defined as: CMV infection detected by a positive result from a CMV laboratory assay from at least one central laboratory assay (pp65 antigenemia or CMV DNA PCR assay in plasma) and fever \>/=38 °C on \>/=2 occasions \>/=24 hours apart within a 7-day period and at least one of the following: new or increased malaise, two successive measurements of leucopenia (white blood cell \[WBC\] count \<3500/mm3 or a WBC count decrease of 20% if the cell count prior to onset of clinical symptoms was \>4000/mm3) \>/=24 hours apart, atypical lymphocytosis \>/=5%, and thrombocytopenia. CMV organ disease was defined as described by Ljungman et al., 2002.

Percent of Participants With Acute Graft-Versus-Host Disease (GVHD)Through 6 months post-transplant (Days 1 to 100 and 6 months post-transplant)

Analysis of acute GVHD was based on reported adverse events that mapped to the relevant MedDRA dictionary terms for acute GVHD. The percentage reported is for the occurrence of any grade of acute GVHD.

Percent of Participants With Chronic Graft-Versus-Host Disease (GVHD)Through 6 months post-transplant (Days 1 to 100 and 6 months post-transplant)

Analysis of chronic GVHD was based on reported adverse events that mapped to the relevant MedDRA dictionary terms for chronic GVHD. The percentage reported is for the occurrence of any grade of chronic GVHD.

Plasma Concentration of Maribavir During Treatment12 hours post-dose after 1 and 4 weeks of treatment

Pharmacokinetic (PK) profile sampling was performed to evaluate plasma concentrations of Maribavir. During the study drug administration period, blood samples for this purpose were collected on Day 7 (Week 1) and at Week 4. Every effort was made to ensure that doses were administered 12 hours apart on the day before and on the day of PK sampling. Permissible assessment windows for PK profile sampling purposes were +/- 3 days and +/- 5 days for the 1- and 4- week samples, respectively. Samples were analyzed by a validated liquid chromatography tandem mass spectrometry (LC/MS/MS) method. The validated lower limit of quantitation (LLOQ) in plasma was 0.2 μg/mL.

Plasma Concentration of Maribavir Metabolite VP 44469 During Treatment12 hours post-dose after 1 and 4 weeks of treatment

Pharmacokinetic (PK) profile sampling was performed to evaluate plasma concentrations of VP 44469, a metabolite of Maribavir. During the study drug administration period, blood samples for this purpose were collected on Day 7 (Week 1) and at Week 4. Every effort was made to ensure that doses were administered 12 hours apart on the day before and on the day of PK sampling.
