Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Dose Limiting Toxicities [ Time Frame: 28 Days after administration of Orca-Q/OrcaGraft ]
    Safety and tolerability of Orca-Q (formerly OrcaGraft) in adults undergoing myeloablative allogeneic hematopoietic cell transplantation (MA-alloHCT) will be evaluated by identification of the following dose limiting toxicities: Grade ≥ 3 infusion-related reaction or cytokine release syndrome, Grade ≥ 3 acute GVHD, Any Grade ≥ 3 treatment-related non-hematologic event not clearly related to the underlying malignancy, intercurrent infection, the HCT conditioning regimen, or other pre-existing medical condition, and by instance of primary graft failure, defined as being alive without recovery of neutrophils during the evaluation period

  2. Primary Graft failure through Day +28 (dose expansion) [ Time Frame: 28 Days after administration of Orca-Q/OrcaGraft ]
    Primary graft failure in the dose expansion phase, defined as being alive without recovery of neutrophils during the evaluation period


Secondary Outcome Measures :
  1. Neutrophil Engraftment through Day +28 [ Time Frame: 28 days after administration of Orca-Q/OrcaGraft ]
    Neutrophil engraftment defined as an absolute neutrophil count of >/=500/mm3 for 3 consecutive days

  2. Platelet engraftment through Day +50 [ Time Frame: 50 days after administration of Orca-Q/OrcaGraft ]
    Platelet engraftment is defined as achieving a platelet count > 20,000/mm3 for 3 consecutive days without platelet transfusion in the preceding 7 days, by Day +50

  3. Secondary graft failure through Day +100 [ Time Frame: 100 days after administration of Orca-Q/OrcaGraft ]
    Secondary graft failure is defined as neutrophil engraftment followed by subsequent decline in absolute neutrophil counts < 500 cells/μL, unresponsive to growth factor therapy, by Day +100

  4. Treatment-emergent adverse events (TEAEs) through the safety reporting period [ Time Frame: 100 days after administration of Orca-Q/OrcaGraft ]
    TEAEs categorized by System Organ Lass and graded according to the CTCAE v5.0

  5. Acute GVHD through Day +100 [ Time Frame: 100 days after administration of Orca-Q/OrcaGraft ]
    Acute GVHD will be staged and graded per Mount Sinai Acute GvHD International Consortium (MAGIC) Standardization criteria

  6. Steroid-refractory acute GVHD through Day +100 [ Time Frame: 100 days after administration of Orca-Q/OrcaGraft ]
    Steroid-refractory acute GVHD will be defined as per the EBMT-NIH-CIBMTR Task Force position statement

  7. Chronic GVHD through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    Chronic GVHD will be diagnosed per 2014 International NIH Chronic GVHD Diagnosis and Staging Consensus Working Group criteria

  8. Post-Transplant Lymphoproliferative Disorder (PTLD) through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    PTLD is defined as a biopsy consistent with the 2017 World Health Organization (WHO) classification of PTLD

  9. Incidence of non-relapse mortality (NRM) through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    NRM is defined as death without evidence of disease recurrence

  10. Incidence of disease relapse through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    Recurrence of primary disease for transplant

  11. GVHD-free and relapse-free survival (GRFS) through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    Survival free from GVHD and relapse

  12. Disease-free survival (DFS) through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    Disease-free survival is the time from date of transplant to death or relapse, whichever comes first.

  13. Overall survival through Day +365 [ Time Frame: 365 days after administration of Orca-Q/OrcaGraft ]
    OS is defined as the time from the date of transplant to the date of death from any cause or, for surviving patients, to the date of last follow-up.
