Neurogene Inc.’s disclosure June 30 of its registrational trial design in Rett syndrome (RS) added spice to the space, where Taysha Gene Therapies Inc. is another closely watched player. The New York-based firm said Embolden will test NGN-401, a gene therapy for the treatment of females age 3 and older with RS. U.S. regulators have signed off regarding key aspects of Embolden’s structure.
Neurogene Inc.’s stock sank 43% on news that its phase I/II gene therapy, NGN-401, resulted in a serious adverse event in a pediatric Rett syndrome patient receiving the highest dose.
After the U.S. FDA granted clearance in March 2023, sales began promptly of Acadia Pharmaceuticals Inc.’s new Rett syndrome therapy, Daybue (trofinetide), and questions during the recent J.P.

Other players include Anavex Life Sciences Corp., Neurogene Inc. and Taysha Gene Therapies Inc.
Neurogene Inc. has received FDA clearance of its IND application for NGN-401 for the treatment of Rett syndrome. The company plans to initiate a phase I/II trial in female pediatric patients with Rett syndrome this year.
The recent start of Neurogene Inc.’s first-in-human trial testing NG-101 in ceroid lipofuscinosis type 5 (CLN5) Batten disease (BD) drew investor attention to the space, where a handful of developers vie for new therapies against the challenging indication.
Money is flowing into gene therapy as investors have started looking favorably on the risk-reward prospects of the space. "I believe the risk has really substantially decreased as regulatory path has become clearer. There are more projects with lower risk," said Sarah Bhagat, a partner at Sofinnova Investments.
A third-quarter progress report from the international advocacy group Alliance for Regenerative Medicine (ARM) has determined that the regenerative medicine and advanced therapy (RMAT) sector established a highwater mark of $15.9 billion in global financings, breaking the previous annual record of $13.5 billion that was set in 2018.
