Precision-T: A Randomized Study of Orca-T in Recipients Undergoing Allogeneic Transplantation for Hematologic Malignancies

Running, not enrolling · Phase 3

Conditions studied: Acute Myeloid Leukemia, Acute Lymphoid Leukemia, Mixed Phenotype Acute Leukemia, Undifferentiated Leukemia, Myelodysplastic Syndrome, Acute Leukemia, Therapy-Related Myelodysplastic Syndrome

In brief

This study will evaluate the safety, tolerability, and efficacy of Orca-T, an allogeneic stem cell and T-cell immunotherapy biologic manufactured for each patient (transplant recipient) from the mobilized peripheral blood of a specific, unique donor. It is composed of purified hematopoietic stem and progenitor cells (HSPCs), purified regulatory T cells (Tregs), and conventional T cells (Tcons) in participants undergoing myeloablative allogeneic hematopoietic cell transplant transplantation for hematologic malignancies. This posting represents the Phase III component of Precision-T. The Precision-T Ph1b component is described under NCT04013685.
