The US Food and Drug Administration has approved a new allogeneic encapsulated, cell-based gene therapy for a rare neurodegenerative disease that affects the macula, a portion of the eye that processes central vision. The product, Encelto (revakinagene taroretcel) is a therapy that delivers a recombinant protein to the retina to slow down the progression of the disease. Delivery is by way of a surgical intravitreal implant by an ophthalmologist.
