Study Details

Study Description

Brief Summary

The goal of this clinical trial is to determine the safety and feasibility of allogeneic transplantation with bone marrow from a deceased donor in patients with acute leukemias. Patients will either receive myeloablative conditioning or reduced intensity conditioning regimen prior to the transplant. Patients will be followed for 56 days for safety endpoints and remain in follow-up for one year.

  • Outcome Measures

    Primary Outcome Measures

    1. Neutrophil Engraftment [Day 28]

      Neutrophil engraftment is defined as achieving an absolute neutrophil count (ANC) of greater than or equal to 500/µL for 3 consecutive measurements on 3 different days by Day 28.

    2. Serious Adverse Events [Day 56]

      Occurrence of any event classified as SAE. The time of occurrence of each serious adverse event will be recorded.

    3. CTCAE Grade 3/4 Adverse Events (AEs) [Day 56]

      Occurrence of any event classified as grade 3/4 AE attributed to Ossium HPC, Marrow per the CTCAE v5.0 guidelines. The time of the occurrence of each event will be recorded.

    4. CTCAE Grade 3 or higher infusion-related toxicity [Day 56]

      Occurrence of any event classified as grade 3 infusion-related toxicity per the CTCAE v5.0 guidelines. The time of the occurrence will be recorded.

    5. Death [Day 56]

      The time of death will be recorded for each expired patient.

    Secondary Outcome Measures

    1. Cumulative incidences of neutrophil engraftment [Day 28]

      Neutrophil engraftment in defined as achieving an absolute neutrophil count (ANC) of greater than or equal to 500/µL for 3 consecutive measurements on different days by Day 28.

    2. Cumulative incidences of platelet recovery [Day 56]

      Platelet recovery is defined as platelets greater than or equal to 20,000/µL for 3 consecutive days in the absence of transfusion for 7 consecutive days by Day 56.

    3. Cumulative incidence of disease relapses [Day 365]

      The cumulative incidence of relapse is measured from the date of transplant (Day 0) until the date of relapse or progression; patients not known to have relapsed are censored on the date they were last examined; patients who died without relapse are counted as a competing cause of failure.

    4. Transplant-related mortality (TRM) [Day 100 and Day 365]

      TRM is defined as death without evidence of disease progression or recurrence.

    5. Cumulative incidences of acute (aGVHD) Graft Versus Host Disease [Day 100, Day 180, and Day 365]

      aGVHD is defined as any skin, gastrointestinal or liver abnormalities fulfilling the criteria of grades II-IV or grades III-IV.

    6. Cumulative incidences of chronic (cGVHD) Graft Versus Host Disease [Day 100, Day 180, and Day 365]

      cGVHD is defined per National Institutes of Health (NIH) Consensus Criteria and includes organ involvement and severity, and overall global composite score (mild/moderate/severe).

    7. Incidence of clinically-significant infections [Day 100 and Day 365]

      A clinically significant infection is defined as any microbiologic or radiographic infection for which antimicrobial therapy was administered.

    Other Outcome Measures

    1. Length of Stay in Hospital [Day 100 and Day 365]

      Cumulative days alive and out of the hospital in the first 100 days and in the first year post-transplant.

    2. Time to provide Ossium product to the patient from product availability request [Day 365]

      Time to find a donor in the Ossium registry and the time to provide Ossium HPC, Marrow product to recipient (time from donor availability request to delivery of product to transplant center).
