HUIDAGENE THERAPEUTICS RECEIVES FDA RARE PEDIATRIC DISEASE DESIGNATION FOR HG004 TO TREAT INHERITED BLINDNESS

"We are pleased to have received another significant regulatory feedback from the US FDA underscoring the dire need for a treatment option of this devastating inherited blindness," said Linyu Shi, Ph.D., Co-founder and Chief Scientific Officer of HuidaGene. "Data from our preclinical studies have shown that HG004 demonstrates significant superiority than AAV2-hRPE65 (LUXTURNA like) in the recovery of retinal function of the Rpe65-/- mice. We are committed to delivering transformative genetic medicines for rare genetic diseases globally."

About Inherited Retinal Disease Caused by RPE65 Mutations
Inherited retinal disease (IRD) is a group of rare blinding conditions caused by mutations in any 1 of more than 250 genes. Leber's congenital amaurosis (LCA), severe early childhood-onset retinal dystrophy (SECORD), early-onset severe retinal dystrophy (EOSRD), and retinitis pigmentosa (RP), which may all be grouped under the heading of inherited retinal disease caused by RPE65 mutations (RPE65-IRD), are considered to represent a phenotypic continuum of the same disease. The RPE65-IRD with a typical onset between birth and five years of age exhibits several common clinical findings, chiefly night blindness, progressive loss of visual fields, and loss of central vision. Given the often severe and early visual loss associated with RPE65-IRD, other areas of development, including speech, social skills, and behavior, may also be delayed.
