Atsena Therapeutics announced 12-month safety and efficacy data from its Phase I/II trial of ATSN-101, a gene therapy for Leber congenital amaurosis caused by biallelic mutations in GUCY2D, published in The Lancet. ATSN-101 demonstrated durable, clinically significant improvements in vision at the high dose and was well-tolerated. This marks the first gene therapy treatment for LCA1, with potential for a Phase III trial.
