BrainStorm, which has a history of antagonizing FDA with direct appeals to patients for NurOwn, tells investors that public elements of an adcomm could be ‘persuasive,’ but first step will be formal meeting request to try to overcome the RTF. Firm sees Relyvrio as template for success.

Agency’s action plan for rare neurodegenerative diseases maps out over five years, but knowledge gained can inform products currently in development; new FDA grant program looks to invest in remote use of clinical outcome assessments for amyotrophic lateral sclerosis.

BrainStorm discovered a statistical error while preparing the stem cell therapy's BLA, and corrected data show a statistically significant treatment difference for a key secondary endpoint in less advanced ALS. However, the Phase III trial still failed its primary clinical efficacy endpoint.

The US FDA is set for two high-profile advisory committee meetings on potential ALS treatments before the end of 2022. Whatever the outcome, they will fit a pattern: when it comes to ALS treatments, there is very little about the regulatory process that feels routine.
