Patient reported outcomes with Orca-T® from the pivotal Precision-T Phase 3 study will be presented including quality of life and rates of rehospitalizations compared to conventional alloHSCT 
Data evaluating the use of Orca-T with reduced intensity conditioning versus PTCy for the treatment of hematologic malignancies will be shared  
Additional presentations will highlight the manufacturing and nationwide distribution data reported on Orca–T and clinical findings of Orca-Q® in patients with haploidentical donors 

MENLO PARK, CA, March 2, 2026  Orca Bio, a late-stage biotechnology company committed to transforming the lives of patients through high-precision cell therapy, today announced that clinical data will be presented in seven oral and poster sessions at the 52nd Annual Meeting of the EBMT from March 22-25 in Madrid. 

 

The encore presentations will include data on the company's pipeline of investigational allogeneic T-cell immunotherapies for the treatment of multiple hematologic malignancies, including Orca-T and Orca-Q. 

 

“Our participation at this year’s meeting of the EBMT provides an important opportunity to engage directly with the global transplant community as we continue our shared efforts to advance the field of allogeneic stem cell transplant,” said Nate Fernhoff, Ph.D., co-founder and chief executive officer of Orca Bio. “As we progress toward the potential FDA approval of Orca-T, the strength and consistency of our data reinforce our commitment to delivering a new therapy for patients with blood cancer.
