Orca Bio to Present Positive Clinical Data on its Novel High-Precision Cell Therapies at the 65th American Society of Hematology Annual Meeting

– The first oral presentation will demonstrate the performance of Orca-T in patients over 55 years of age compared with younger patients –

– A second oral presentation will highlight Orca-Q, Orca Bio’s high-precision cell therapy for patients with haploidentical donors –

– Additional poster presentations include outcomes in patients with high-risk myelodysplastic syndrome treated with Orca-T and results of Orca-T in patients undergoing reduced intensity conditioning –

MENLO PARK, Calif.--(BUSINESS WIRE)--Orca Bio, a late-stage biotechnology company developing high-precision cell therapies for the treatment of cancer, autoimmune diseases and genetic blood disorders, today announced that new data will be presented at the American Society of Hematology (ASH) Annual Meeting from December 9-12 in San Diego, CA. Specifically, an oral presentation will highlight the outcomes of myeloablative Orca-T, Orca Bio’s lead investigational high-precision cell therapy, in patients over the age of 55. A second oral presentation will share updated results in an expanded group of patients with haploidentical donors treated with Orca Bio’s second investigational high-precision cell therapy, Orca-Q.

Orca Bio will also present two posters highlighting the results of patients with high-risk myelodysplastic syndrome who were treated with Orca-T, and the outcomes of patients treated with Orca-T who received reduced intensity conditioning.

The ASH abstracts are now available at www.hematology.org. Details of the Orca Bio presentations follow:

About Orca-T

Orca-T is an investigational high-precision allogeneic cell therapy for the treatment of multiple hematological malignancies. Orca-T includes infusions containing regulatory T-cells, CD34+ stem cells and conventional T-cells derived from peripheral blood from either related or unrelated matched donors. Orca-T is currently being evaluated in a pivotal Phase 3 clinical trial at leading transplant centers across the U.S. and has received Regenerative Medicine Advanced Therapy (RMAT) designation from the U.S. Food and Drug Administration.

About Orca-Q

Orca-Q is an investigational high-precision allogeneic cell therapy designed to treat hematological malignancies in patients with haploidentical 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. Orca-Q has the potential to improve patient outcomes and reduce the risks of toxicities without the use of post-transplant cyclophosphamide (PTCy) in patients unable to identify a full human leukocyte antigen (HLA) match.
