A modification of the CRISPR technique has made it possible to restore vision in mouse models with retinitis pigmentosa (RP). Scientists at the Institute of Visual Neuroscience and Stem Cell Engineering of Wuhan University of Science and Technology developed a new gene-editing tool called PE(SpRY) to edit in vivo a mutation of enzyme phosphodiesterase 6B (PDE6β) and return its function.
Patients with Leber hereditary optic neuropathy who received bilateral injections of Gensight Biologics SA’s Lumevoq (lenadogene nolparvovec) are continuing to see statistically significant visual improvements three years into the phase III REFLECT trial, but the missed primary endpoint at 1.5 years, along with a series of manufacturing mishaps, have left the gene therapy’s approval prospects uncertain.
Abeona Therapeutics Inc. has announced three investigational preclinical gene therapy product candidates from its ophthalmology program. The new AAV-based therapies use novel AAV capsids from Abeona's in-licensed AIM capsid library. Abeona intends to submit its first pre-IND application meeting request this month.
Praetego Inc. has been granted a US$300,000 phase I Small Business Technology Transfer Research (STTR) award by the National Eye Institute (NEI) to advance the company's lead candidate, PTG-630, into preclinical proof of concept in diabetic retinopathy.
Ophthalmic startup Eluminex Biosciences Ltd. closed a $40 million series B round to progress its pipeline of ophthalmic assets and recombinant human collagen technology. Eluminex’s pipeline includes multi-targeted antibody molecules for vision-threatening retinal diseases and an oral small molecule for rare inherited pediatric retinal dystrophies, but its lead asset, EB-301, is a biosynthetic cornea derived from recombinant human type III collagen.
Aldeyra Therapeutics Inc. is eyeing the start of clinical trials with reactive aldehyde species (RASP) modulators ADX-246 for systemic immune-mediated diseases and ADX-248 for geographic atrophy.
After a delay in November that resulted in a new PDUFA date, Apellis Pharmaceuticals Inc.’s Syfovre (pegcetacoplan injection) received U.S. FDA approval for treating geographic atrophy (GA) secondary to age-related macular degeneration. While this is the first and only FDA-approved treatment for GA, there is competition afoot from Belite Bio Inc. and Iveric Bio Inc. The intravitreal targeted C3 therapy’s Feb. 17 approval of the priority NDA came more than a week ahead of its Feb. 26 PDUFA.
