About TREGZI™
TREGZI™ is the first-and-only FDA approved precision-cell therapy for allogeneic transplant in adults with hematologic malignancies to improve survival free of cGVHD. It is indicated for use in matched donor hematopoietic stem cell transplantation with myeloablative preparative regimen, for hematopoietic and immunologic reconstitution and to improve chronic graft-versus-host-disease-free survival, in the treatment of adults with hematological malignancies.
TREGZI is a personalized treatment manufactured for each individual patient using living cells from a matched donor. TREGZI uses hematopoietic stem and progenitor cells (HSPCs) to reconstitute the immune system, highly purified regulatory T cells (Tregs) to suppress GVHD and conventional T cells (Tcons) to accelerate immune reconstitution and produce graft-versus-leukemia (GVL) activity.
The FDA approval of TREGZI was based on the results of Precision-T, a randomized, open-label, multi-center study that evaluated the safety, efficacy and tolerability of TREGZI compared with conventional allogeneic hematopoietic stem cell transplant (alloHSCT).
About Orca-Q®
Orca-Q® is Orca Bio’s second-generation investigational allogeneic T-cell immunotherapy being evaluated in clinical trials for the treatment of multiple hematologic malignancies, including in patients with haploidentical and mismatched donors. Orca-Q is a proprietary composition of stem cells combined with specific T-cell subsets derived from healthy donors and engineered by Orca Bio’s high-precision platform.
