研究组 & 干预措施
Letermovir
Experimental
Chinese HSCT recipients will receive 240 mg of Letermovir [for participants on Cyclosporin A (CsA)] or 480 mg of Letermovir (for participants not on CsA) either orally or IV once daily through week 14 (~100 days) post-transplant.
干预措施: Letermovir (Drug)
结局指标
主要结局
Percentage of Participants With Clinically Significant Cytomegalovirus (CMV) Infection up to Week 24 Post-Transplant
时间窗: Up to Week 24 post-transplant (approximately 6 months)
Clinically significant CMV infection was defined as either one of the following: 1) initiation of anti-CMV pre-emptive therapy based on documented CMV viremia and the clinical condition of the participant or 2) onset of CMV end-organ disease. The percentage of participants with clinically significant CMV infection up to week 24 post-transplant is reported.
次要结局
- Percentage of Participants Who Experienced an Adverse Event (AE)(Up to 16 weeks)
- Percentage of Participants Who Discontinue Study Treatment Due to an Adverse Event(Up to 14 weeks)
- Percentage of Participants With Clinically Significant CMV Infection up to Week 14 Post-Transplant(Up to 14 weeks post-transplant (99 days))
- Percentage of Participants With Preemptive Therapy for CMV Viremia up to Week 14 Post-Transplant(Up to 14 weeks post-transplant (99 days))
- Percentage of Participants With Preemptive Therapy for CMV Viremia up to Week 24 Post-Transplant(Up to 24 weeks post-transplant (approximately 6 months))
- Percentage of Participants With CMV End-organ Disease up to Week 14 Post-Transplant(Up to 14 weeks post-transplant (99 days))
- Percentage of Participants With CMV End-organ Disease up to Week 24 Post-Transplant(Up to 24 weeks post-transplant (approximately 6 months))
- Percentage of Participants With All-Cause Mortality up to Week 14 Post-Transplant(Up to 14 weeks post-transplant (99 days))
- Percentage of Participants With All-cause Mortality up to Week 24 Post-Transplant(Up to 24 weeks post-transplant (approximately 6 months))
