Ocugen Announces OCU400 Receives Orphan Drug Designations for Retinitis Pigmentosa and Leber Congenital Amaurosis

December 15, 2022

U.S. Food & Drug Administration (FDA) acknowledges the potential of OCU400 to treat rare inherited retinal diseases

MALVERN, Pa., Dec. 15, 2022 (GLOBE NEWSWIRE) -- Ocugen, Inc. (Ocugen or the Company) (NASDAQ: OCGN), a biotechnology company focused on discovering, developing, and commercializing novel gene and cell therapies and vaccines, today announced that the FDA granted orphan drug designations to OCU400—human nuclear hormone receptor subfamily 2 group E member 3 (hNR2E3)—for the treatment of retinitis pigmentosa (RP) and Leber congenital amaurosis (LCA).

“Receiving orphan drug designation is incredibly encouraging at this stage in the development of OCU400,” said Arun Upadhyay, PhD, Chief Scientific Officer, Ocugen. “We are excited by the potential of OCU400, a nuclear hormone-based modifier gene therapy product, to treat RP and LCA in a gene agnostic manner. We look forward to working collaboratively with the FDA and other agencies to progress OCU400 through clinical development to commercialization.”

Orphan drug designation is a status given to certain drugs that show promise in the treatment, prevention, or diagnosis of orphan diseases. An orphan disease is a rare disease or condition that affects fewer than 200,000 people in the United States.

Currently, RP is associated with mutations in more than 100 genes, affecting approximately 110,000 people in the United States (U.S.). LCA is associated with mutations in more than 25 genes, affecting approximately 10,000 people in the U.S. There are currently no treatment options available for patients living with RP and LCA, and OCU400 has the potential to treat both with a single product.

OCU400 represents Ocugen’s modifier gene therapy approach, which is based on Nuclear Hormone Receptors (NHRs) that regulate diverse physiological functions, such as homeostasis, reproduction, development, and metabolism to potentially improve retinal health and function.
