研究概览
简要总结
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.
详细描述
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.

结局指标
主要结局
Number of Participants With Endpoint Committee (EC)-Confirmed Cytomegalovirus (CMV) Disease Within 6 Months Post-Transplantation
时间窗: 6 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.
