FDA Snubs Brainstorm ALS Therapy Data
BrainStorm Cell Therapeutics says FDA told it that the “current level of clinical data does not provide the threshold of substantial evidence” that the agency is seeking to support a BLA for NurOwn (autologous MSC-NTF cells) for treating amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease). The FDA feedback on a “high-level data summary” from the NurOwn ALS Phase 3 clinical trial also said that the company is not precluded from proceeding with a BLA submission, if it chooses, according to BrainStorm.
The company says it will first consult with principal investigators, ALS experts, expert statisticians, regulatory advisors, and ALS advocacy groups to assess the benefit/risk of the proposed BLA submission before making a final decision. It describes NurOwn as a “promising investigational approach to targeting disease pathways important in neurodegenerative disorders MSC-NTF cells are produced from autologous, bone marrow-derived mesenchymal stem cells (MSCs) that have been expanded and differentiated ex vivo. MSCs are converted into MSC-NTF cells by growing them under patented conditions that induce the cells to secrete high levels of neurotrophic factors. Autologous MSC-NTF cells can effectively deliver multiple NTFs and immunomodulatory cytokines directly to the site of damage to elect a desired biological effect and ultimately slow or stabilize disease progression.”
