Expanding the life-changing benefits of cell therapies


Our mission
At Orca Bio, our mission is to transform the lives of patients through high-precision cell therapy. We are focused on expanding treatment to as many patients who could benefit by developing allogeneic T-cell immunotherapies for the treatment of blood cancer and autoimmune diseases.
Orca Bio’s lead investigational allogeneic T-cell immunotherapy, Orca-T, is being evaluated in a pivotal Phase 3 trial called Precision-T for the treatment of acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL) and myelodysplastic syndrome (MDS). In parallel, we are advancing our pipeline in blood cancer, autoimmune diseases, and beyond.
Patients shouldn’t have to settle
At Orca Bio, we are continuously working to ensure they won’t have to
The leadership team at Orca Bio includes our company founders and other industry veterans who are focused on redefining what the future could mean for patients.
