The purpose of the study is to determine if overall mortality is affected one year after a hematopoietic stem cell transplant (HCT) in patients given a vaccine to prevent cytomegalovirus (CMV). Safety of ASP0113 in subjects undergoing allogeneic HCT will also be evaluated.

Primary Outcome Measures:
  • Overall mortality [ Time Frame: One year post-transplant ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to first protocol-defined cytomegalovirus (CMV) viremia [ Time Frame: One year post transplant ] [ Designated as safety issue: No ]
    CMV viremia defined as CMV plasma viral load ≥ 1000 IU/mL as assessed by the central laboratory

  • Time to first adjudicated CMV-specific anti-viral therapy (AVT) [ Time Frame: One year post-transplant ] [ Designated as safety issue: No ]
  • Time to first CMV-specific AVT for protocol-defined CMV viremia or CMV end organ disease (EOD) [ Time Frame: One year post-transplant ] [ Designated as safety issue: No ]
  • Incidence of grade 3 treatment-emergent infections other than CMV [ Time Frame: One year post-transplant ] [ Designated as safety issue: No ]
  • Time to grade 3 treatment-emergent infections other than CMV [ Time Frame: One year post-transplant ] [ Designated as safety issue: No ]

Detailed Description:

The study will be divided into two parts. Part 1 of the study will include the first 100 subjects who are randomized. The purpose of Part 1 is to collect efficacy results to evaluate treatment effect on the primary endpoint and other efficacy endpoints to potentially modify the primary endpoint for being specified for Part 2 of the study.

Part 2 will include the subsequent 400 subjects to evaluate the vaccine efficacy on the incidence of the primary endpoint through one year post-transplant.
