FDA Approves Orca-T (Tregzi), First Regulatory T Cell-Based Immunotherapy to Prevent Chronic GVHD
The FDA approved Tregzi (Orca-T), a first-of-its-kind regulatory T cell-based immunotherapy, for adults with blood cancers undergoing matched donor stem cell transplants. Approval was based on the PRECISION-T trial, in which 78% of treated patients achieved chronic GVHD-free survival at one year versus 38.4% with standard transplant.
