Preclinical data support novel approaches for the treatment of Usher Syndrome 2A and retinitis pigmentosa 4

CAMBRIDGE, Mass., May 01, 2021 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, today announced that two scientific abstracts have been accepted for presentation at the Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting being held virtually May 1 – 7, 2021. The Company is presenting preclinical data on its Usher Syndrome 2A (USH2A) and retinitis pigmentosa 4 (RP4) programs.

Editas Medicine’s presentations at ARVO will include preclinical data demonstrating:

  • Gene edited USH2A exon 13 deletion restored USH2 protein complex expression and rescued deficits in photoreceptor morphology in human retinal organoids; and
  • Clinically relevant levels of editing using a dual AAV CRISPR-Cas9 system as a therapeutic strategy for the treatment of RP4.

“Editas Medicine is making significant advancements in our efforts to treat ocular diseases, and we look forward to sharing recent progress and preclinical data on our USH2A and RP4 programs this week at the ARVO Annual Meeting,” said Kate Zhang, Vice President, Biological Development, Editas Medicine. “This data further supports our advancing these programs towards the clinic and our belief in the potential for gene editing medicines to transform the lives of those living with inherited retinal diseases.”
