A randomized, open-label multicenter study, Precision-T (NCT05316701) is evaluating the safety and efficacy of Orca Bio’s lead investigational allogeneic T-cell immunotherapy, Orca-T, compared to a standard of care allogeneic hematopoietic stem cell transplant (alloHSCT) in patients with acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL) and high-risk myelodysplastic syndrome (MDS). Orca-T is a donor-derived product designed to replace a patient’s diseased blood and immune system with a healthy one.
"Completing enrollment in our multicenter Phase 3 study of Orca-T is an important milestone toward our ultimate goal of delivering a potentially life-saving product to patients who have long had to settle for a standard of care that carries significant risks," said Ivan Dimov, Ph.D., co-founder and chief executive officer of Orca Bio. "We’re immensely grateful to the patients, their families and the trial site investigators who participated in our study, and look forward to sharing pivotal data in the near future with the broader blood cancer community."
The primary endpoint of the Precision-T study is the rate of survival free from moderate-to-severe chronic graft versus host disease (GvHD). Secondary endpoints include time to moderate-to-severe chronic GvHD, graft-versus-host-disease and relapse-free survival (GRFS) and overall survival. Topline results from the study are expected in the first half of 2025. The study has enrolled 187 patients, exceeding the original target of 174 patients.
Orca-T is designed to deliver improved outcomes for patients while overcoming the limitations of standard alloHSCT, which carries the risk of serious complications and treatment-related mortality. Orca-T uses highly purified regulatory T cells with the goal of reducing the tradeoff between the risk of relapse and the risk of serious toxicity, a primary objective of the cell therapy field. Orca-T has demonstrated promising results in early single-arm trials which were recently presented at the 2024 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting the Annual Meeting of the EBMT, the 2024 Tandem Meetings of ASTCT and CIBMTR and the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting.
