FDA priority review of BLA for eli-cel gene therapy for cerebral adrenoleukodystrophy (CALD) in patients without a matched sibling donor.- bluebird bio.

Eli-cel is an investigational one-time gene therapy, custom-designed to treat the underlying cause of this irreversible neurodegenerative disease and to stabilize neurologic function. The agency set a Prescription Drug User Fee Act (PDUFA) goal date of June 17, 2022.

If approved, eli-cel will be the first approved treatment to address the underlying genetic cause of disease for patients living with CALD in the U.S. – offering appropriate patients an alternative to allogeneic hematopoietic stem cell transplant (allo-HSCT), which is associated with serious potential complications and mortality that increase in patients without a matched sibling donor. It is estimated that more than 70% of patients diagnosed with CALD do not have a matched sibling donor.
