Enrollment | 514 |
Participant Flow
Recruitment Details | A total of 514 participants were enrolled across 11 countries. At least 30% of enrolled participants had cytomegalovirus (CMV) seronegative donor and underwent allogeneic hematopoietic cell transplant (HCT). After the primary study period (day 365) participants were monitored for 5.5 years post-transplant for long-term safety. After the primary period completion, 326 participants entered the long-term follow-up period. |
Pre-assignment Details | Screening assessment occurred from 30 to 5 days before transplant. Participants who met the inclusion and none of the exclusion criteria were randomly assigned in a 1:1 ratio to receive either ASP0113 or placebo. The randomization to treatment was stratified by donor-recipient relatedness and by donor CMV serostatus. |

Participants received 1 mL of 5 mg/mL of matching placebo via intramuscular injection in the deltoid muscle alternating sides with each dose on days -14 to -3 pretransplant, 14 to 40, 60, 90 and 180 in relation to the day of transplant (Day 0). | Participants received 1 mL of 5 mg/mL of ASP0113 via intramuscular injection in the deltoid muscle alternating sides with each dose on days -14 to -3 pretransplant, 14 to 40, 60, 90 and 180 in relation to the day of transplant (Day 0). |
