Orphan Designation for Retinal Gene Therapy
FDA has granted an orphan drug designation for its novel gene therapy (OCU400) for treating the CEP290 mutation-associated retinal disease. Inherited retinal diseases are caused by genetic mutations that are passed down within families and lead to visual impairment and blindness. Mutations in CEP290 have been associated with different diseases including Leber Congenital Amaurosis, Bardet-Biedl syndrome, Joubert syndrome, Senior-Loken syndrome and Meckel-Gruber syndrome, the company says.
"The nuclear hormone receptor gene, NR2E3, plays a major role in modulating numerous biological pathways that are essential for maintaining the healthy status of the retina, both anatomically and functionally,” the company says. It says the gene therapy is designed to supply an elevated level of NR2E3 to target cells in the retina using an adeno-associated viral vector.
