FDA Refuses to File NurOwn BLA

FDA has issued a refusal to file letter to BrainStorm Cell Therapeutics for its BLA for NurOwn to treat ALS (amyotrophic lateral sclerosis). The company says FDA said it could request a Type A meeting with the agency to discuss the content of the letter.

Company officials said they plan to request the meeting with FDA and remain committed to NurOwn’s development as an ALS treatment.

BrainStorm says the NurOwn technology platform (autologous MSC-NTF cells) “represents a promising investigational therapeutic approach to targeting disease pathways important in neurodegenerative disorders.” MSC-NTF cells are described as “autologous, differentiated bone-marrow-derived mesenchymal stem cells (MSC) that secrete neurotrophic factors (NTFs), regulatory miRNAs that demonstrate neuroprotection and immunomodulation in preclinical models.”
