Orca Bio Data Shows Orca-T Outperforms Standard Care in Blood Cancers
Event summary
- Orca-T demonstrated superior one- and two-year overall survival rates (88% vs. 72%, 84% vs. 61%) compared to standard post-transplant cyclophosphamide in a Phase 1 trial.
- Phase 2 SERENE-T study for AML/MDS patients with reduced intensity conditioning began dosing first patients at three U.S. centers in early 2026.
- Orca-Q showed promising results in haploidentical donor setting with 85% one-year overall survival in TFT subgroup.
- Manufacturing analysis confirmed 100% on-time delivery of 243 cell therapies to U.S. transplant centers between 2019-2024.
The big picture
Orca Bio's data reinforces the potential of its high-precision cell therapy platform to address critical unmet needs in blood cancer treatment. The consistent manufacturing performance and superior clinical outcomes compared to standard care position Orca-T as a potential game-changer in allogeneic stem cell transplantation, particularly for older patients with hematologic malignancies.
