Inclusion Criteria

  • Male or female subjects, ≥12 years of age (≥ 18 years of age for subjects at German sites only), undergoing HCT for hematological malignancies, including leukemia, lymphoma multiple myeloma, myelodysplastic syndrome and myeloproliferative neoplasms.
  • Planned myeloablative conditioning regimen.
  • Participants must have a related or unrelated donor as follows: - Related donor must be a 6 / 6 match for human leukocyte antigen (HLA)-A, -B, at intermediate (or higher) resolution, and -DR beta 1 (DRB1) at high resolution using deoxyribonucleic acid (DNA)-based typing. - Unrelated donor must be 7 / 8 or 8 / 8 match for HLA-A, -B, and -C at intermediate (or higher) resolution, and -DRB1 at high resolution using DNA-based typing.

Exclusion Criteria

  • Prior autologous or allogeneic HCT.
  • T-cell depleted transplant or planned use of anti-T cell antibody therapy either ex vivo or in vivo (ie, anti‑thymocyte globulin [ATG], alemtuzumab) for GVHD prophylaxis.
  • Planned umbilical cord blood transplant.
  • Planned use of cyclophosphamide after HCT for GVHD prophylaxis.
  • Planned haploidentical donor.
