    Study Title:

    A First-in-Human Study of HLA-Partially to Fully Matched Allogenic Cryopreserved Deceased Donor Bone Marrow Transplantation for Patients with Hematologic Malignancies


    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.


    Primary Objectives: 1. To determine neutrophil engraftment by Day 28 2. To determine primary safety in using Ossium HPC, Marrow as defined as the absence of CTCAE grade 3 or higher adverse events (AEs) attributed to Ossium HPC, Marrow and primary graft failure by Day 28 3. To determine serious adverse events (SAEs), CTCAE Grade 3/4 AEs, and death attributed to and within 56 days after infusion of Ossium HPC, Marrow Secondary Objectives: 1. To determine cumulative incidences of neutrophil engraftment (ANC ≥500/μL for 3 consecutive days) on Day 28 and platelet recovery (platelets ≥20,000/μL for 3 consecutive days in absence of transfusion for 7 days consecutive days) by Day 56 2. To determine cumulative incidences of acute and chronic graft versus host disease (aGVHD and cGVHD, respectively), transplant related mortality (TRM), and disease relapse 3. To determine incidence of clinically significant infections
