Official Title: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter, Phase 3 Study of the Safety, Tolerability, and Efficacy of CMX001 for the Prevention of Cytomegalovirus (CMV) Infection in CMV-seropositive (R+) Hematopoietic Stem Cell Transplant Recipients

Primary Outcome Measures:
  • The primary efficacy endpoint of this study will be the incidence of clinically significant CMV infection through Week 24 posttransplant [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To describe the effect of CMX001 versus placebo on all cause mortality,non-relapse mortality and on graft failure [ Time Frame: 24 Weeks ] [ Designated as safety issue: Yes ]
    The effect of CMX001 in preventing clinical manifestations associated with non-CMV double-stranded deoxyribonucleic acid (dsDNA) viruses including BKV, HHV-6, AdV and EBV.

Ages Eligible for Study:   18 Years to 89 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects will be adult allogeneic HSCT recipients aged ≥ 18 years-old (or as applicable, per local law) who were CMV seropositive before transplantation and are CMV viremia negative posttransplant.

Exclusion Criteria:

  • Subjects who have a positive CMV viremia test at any time between transplant and the First Dose Day (FDD).
  • Subjects with hypersensitivity (not renal dysfunction or eye disorder) to CDV or to CMX001 or its excipients.
  • Subjects who have received any anti-CMV therapy and investigational anti-CMV drugs at any time posttransplant.
  • Subjects who have had any anti-CMV vaccine at any time.
