Official Title  ICMJE A Multicenter Phase Ib Trial for Patients With Advanced Hematologic Malignancies Undergoing Allogeneic Hematopoietic Cell Transplantation With TregGraft (Orca-T), a T-cell-Depleted Graft With Additional Infusion of Conventional T Cells and Regulatory T Cells
Brief Summary This study will evaluate the safety, tolerability, and efficacy of an engineered donor graft ("TregGraft"/"Orca-T", a T-cell-Depleted Graft With Additional Infusion of Conventional T Cells and Regulatory T Cells) in participants undergoing myeloablative allogeneic hematopoietic cell transplant transplantation for hematologic malignancies.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Acute Myeloid Leukemia
  • Acute Lymphoid Leukemia
  • Myelodysplastic Syndromes
  • Acute Leukemia
Intervention  ICMJE Biological: TregGraft (Orca-T)
engineered donor allograft
Study Arms  ICMJE Experimental: Subjects with Acute Leukemia or Myelodysplasic Syndrome

This is a non-randomized, single-arm study. Patients will be grouped based on their underlying disease:

Group 1 will enroll subjects planning to undergo myeloablative allogeneic hematopoietic cell transplantation (MA-alloHCT) for the treatment of either acute myeloid, lymphoid or mixed phenotype leukemia in complete remission (CR) or CR with incomplete hematologic recovery (CRi), and with no known minimal residual disease positivity.

Group 2 will enroll subjects Subjects planning to undergo MA-alloHCT for acute myeloid, lymphoid or mixed phenotype leukemia that is either:

  • not in morphologic CR with bone marrow infiltration by leukemic blasts of <= 10%, or
  • in morphologic CR with evidence of minimal residual positivity by either multiparameter flow cytometric analysis or by a nucleic acid-based technique.

Group 3 will enroll subjects planning to MA-alloHCT for high or very high risk myelodysplasic syndrome (MDS) myelodysplastic syndromes.

Intervention: Biological: TregGraft (Orca-T)
