BrainStorm Seeks ‘Special Protocol” for ALS Treatment
BrainStorm Cell Therapeutics has submitted a Special Protocol Assessment request for a Phase 3b study of NurOwn, its investigational treatment for amyotrophic lateral sclerosis (ALS). The submission follows an in-person meeting that BrainStorm held with the FDA in December after the company withdrew its BLA for NurOwn, a move the company says was coordinated with FDA. A BrainStorm statement at the time said the agency had invited it to request an expedited face-to-face meeting to discuss a path forward for NurOwn, which includes an additional pivotal trial.
“Participating in an SPA program would allow BrainStorm to reach consensus with the FDA on its clinical trial design, including the proposed statistical analysis, before the study is initiated,” the company says. “This would help ensure that the study would be considered adequate to support a future marketing evaluation.” The response to the SPA request is expected within 45 days of submission, it adds.
The company says the NurOwn technology platform (autologous MSC-NTF cells) “represents a promising investigational therapeutic approach to targeting disease pathways important in neurological disorders. MSC-NTF cells are harvested from each person with ALS and are manufactured using an innovative and proprietary process to secrete neurotrophic factors to target specific neurodegenerative diseases.”
