Precigen Gains Orphan Status for CAR-T Therapy
FDA has granted Precigen an orphan drug designation for PRGN-3006, a first-in-class investigational therapy for treating patients with relapsed or refractory acute myeloid leukemia (AML). PRGN-3006 uses Precigen’s UltraCAR-T therapeutic platform, which the company says “eliminates ex vivo expansion, reduces manufacturing time and provides the ability to administer CAR-T therapy to patients only one day after non-viral gene transfer at the cancer center.” PRGN-3006 is a multigenic CAR-T cell treatment designed to “co-express a chimeric antigen receptor, membrane-bound interleukin-15 (mbIL15), and a kill switch for better precision and control in targeting relapsed or refractory AML,” it says.
