FDA assigns PDUFA target action date of April 6, 2026
If approved, Orca-T would be the first allogeneic T-cell immunotherapy for the treatment of hematological malignancies including acute myeloid leukemia, acute lymphoblastic leukemia and myelodysplastic syndromes
MENLO PARK, Calif.–(BUSINESS WIRE)–Orca Bio, a late-stage biotechnology company committed to transforming the lives of patients through high-precision cell therapy, today announced the U.S. Food and Drug Administration (FDA) has accepted for Priority Review the Biologics License Application (BLA) seeking approval for Orca-T, its lead investigational allogeneic T-cell immunotherapy, for the treatment of hematological malignancies including acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) and myelodysplastic syndromes (MDS).
The FDA granted the BLA Priority Review with a Prescription Drug User Fee Act (PDUFA) target action date of April 6, 2026.
“A stem cell transplant has been the only potentially curative option for many people with AML, ALL or MDS, however treatment-related toxicities too often hinder patient recovery. Acceptance of the Orca-T BLA marks a pivotal moment in our ability to deliver a first-in-class therapy designed to improve survival free from complications like graft versus host disease,” said Nate Fernhoff, Ph.D., co-founder and chief executive officer at Orca Bio. “Supported by positive Phase 3 clinical data, today’s regulatory milestone reflects important recognition of the transformative potential of Orca-T. We look forward to working collaboratively with the FDA on the review of our application with the goal of advancing Orca-T and making it available to patients in need.”
The BLA submission for Orca-T is supported by positive results from the pivotal Phase 3 study, Precision-T (NCT04013685), a randomized, open-label multi-center study that evaluated the safety, efficacy and tolerability of Orca-T compared to conventional allogeneic hematopoietic stem cell transplant (alloHSCT) in patients with AML, ALL and MDS. The study met its primary endpoint of a statistically significant improvement in survival free of moderate-to-severe chronic graft versus host disease (cGvHD) with Orca-T versus alloHSCT.
