Inclusion criteria

  • Participant must be ≥1 year of age at screening and undergoing allogeneic Hematopoietic Stem Cell Transplant (HSCT).
  • Participant must be diagnosed with acute leukemia in morphologic complete remission (CR1 or CR2) or with Myelodysplastic syndrome (MDS) with no circulating blasts and with less than 5% blasts in the bone marrow
  • Participant must have planned to receive either a myeloablative or reduced-intensity conditioning regimen and have an unrelated donor who is human leukocyte antigen (HLA) matched or single-allele mismatched
  • Participant must receive the following medical regimen as part of standard of care immunoprophylaxis for GvHD in either study arm at doses and regimen determined by local institutional guidelines, physician preference, and participant need:

  • Participant had acute bleeding that is clinically significant within 24 hours before the start of study treatment, defined as either of the following:
  • Hemorrhage requiring >15 cc/kg of packed red blood cells (eg, pediatric participant weighing 20 kg and requiring 300 cc packed red blood cells/24 hours, or an adult weighing >70 kg and requiring 3 units of packed red blood cells/24hours) to replace blood loss, or
  • Bleeding from a site which, in the investigator's opinion, constituted a potential life-threatening source (eg, pulmonary hemorrhage or central nervous system bleeding), irrespective of amount of blood loss
  • Participant used any medication that increases the risk of bleeding within 24 hours before the start of study treatment, including, but not limited to, systemic heparin, low molecular weight heparin, heparin analogs, alteplase, streptokinase, urokinase, antithrombin III, oral anticoagulants including warfarin, and other agents that increase the risk of bleeding.

    Time frame: HSCT Day (Day +0 post-HSCT) through Day +100 post-HSCT

    Cumulative Incidence Percentage of Grade B to D aGvHD was defined using the International Bone Marrow Transplant Registry (IBMTR) Severity Index.

    Time frame: HSCT Day (Day +0 post-HSCT) through Days +100 and +180 post-HSCT

    Disease relapse was defined by either morphological evidence of acute leukemia or Myelodysplastic syndrome (MDS) consistent with pre-transplant features, documented or not by biopsy. The event was defined as an increase in size of prior sites of disease or evidence of new sites of disease, documented or not by biopsy. Disease relapse was diagnosed when there was morphological or clinical evidence of the following: reappearance of leukemia blast cells in the peripheral blood, or >5% blasts in the bone marrow (BM), not attributable to another cause (eg, BM regeneration), or the appearance of previous or new dysplastic changes (MDS specific) within the BM, with or without falling donor chimerism, or the development of extramedullary leukemia or leukemic cells in the cerebral spinal fluid, or institution of therapy to treat relapsed disease, including donor lymphocyte infusion.

  5. Cumulative Incidence Percentage of Systemic Steroids for the Treatment of aGvHD +180 Days Post-HSCT

    Time frame: HSCT Day (Day +0 post-HSCT) through Day +180 post-HSCT

    For each treatment arm, the cumulative incidence rate of systemic steroid use for the treatment of aGvHD by Day +180 post-HSCT will be estimated using the cumulative incidence competing risk estimator. The calculation of the cumulative incidence rates and the stratified Gray's test was carried out using the LIFETEST procedure in SAS version 9.4. If the participant experienced a competing risk event, then the initiation date was used to calculate the time-to-event variable.

Change from the baseline assessment to Days +100 and +180 post-HSCT in the index value was assessed. The index value total range is from a minimum value of -1 to a maximum value of +1. A higher EQ-5D-5L index value represents better quality of life (QoL), thus a positive change in the index value represents improved QoL.
