A Study of Engineered Donor Grafts (Orca-T) in Recipients Undergoing Allogeneic Transplantation for Hematologic Malignancies

This study will evaluate the safety, tolerability, and efficacy of an engineered donor graft
("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.
