BrainStorm Cell Therapeutics Submits IND Amendment to FDA, Paving the Way for Phase 3b Trial of NurOwn® in ALS

Rhea-AI Summary

BrainStorm Cell Therapeutics (NASDAQ: BCLI) has submitted an Investigational New Drug (IND) amendment to the FDA for NurOwn®, their autologous mesenchymal stem cell therapy for ALS. The submission paves the way for a Phase 3b clinical trial designed under a Special Protocol Assessment (SPA).

The upcoming trial will enroll approximately 200 ALS participants in two parts: Part A involves a 24-week double-blind period where patients receive three doses of either NurOwn or placebo. In Part B, all participants transition to an open-label extension, receiving three additional NurOwn doses over another 24 weeks. The primary efficacy endpoint will measure changes in ALSFRS-R scores from baseline to week 24.

NurOwn® technology platform uses autologous MSC-NTF cells derived from bone marrow mesenchymal stem cells, engineered to secrete high levels of neurotrophic factors. The therapy has received Orphan Drug designation from both FDA and EMA for ALS treatment.

Positive

• FDA agreement on trial design under Special Protocol Assessment (SPA)
• Clear pathway to potential BLA submission after Part A completion
• All participants will have access to NurOwn treatment in Part B
• Orphan Drug designation from both FDA and EMA

Negative

• Additional Phase 3b trial required before potential approval
• Extended timeline for regulatory approval due to new trial requirement
• No guarantee of successful trial outcomes or FDA approval

NEW YORK, April 10, 2025 /PRNewswire/ -- BrainStorm Cell Therapeutics Inc. (NASDAQ: BCLI), a leading biotechnology company developing cutting-edge cell therapies for neurodegenerative diseases, today announced the submission of an Investigational New Drug (IND) amendment to the U.S. Food and Drug Administration (FDA) for NurOwn^®, the company's autologous mesenchymal stem cell therapy for amyotrophic lateral sclerosis (ALS). This important milestone sets the stage for the initiation of BrainStorm's highly anticipated Phase 3b clinical trial, which has been designed in collaboration with the FDA under a Special Protocol Assessment (SPA). The SPA agreement confirms that the Phase 3b trial design and statistical analysis plan is in line with the FDA's expectations, validating its potential to support a future Biologics License Application (BLA). The company now anticipates a swift regulatory review of the IND, clearing the way for the trial's launch.

"The submission of this IND amendment, together with the FDA's agreement on our trial design under the SPA, represents a major step toward bringing NurOwn to ALS patients," said Chaim Lebovits, CEO of BrainStorm Cell Therapeutics. "We are optimistic about a rapid review and are eager to initiate our Phase 3b study, which we are undertaking to support regulatory approval."

The Phase 3b trial is expected to enroll approximately 200 ALS participants and will be conducted in two parts. In Part A, patients will receive three doses of either NurOwn or placebo over a 24-week double-blind period. Following this, all participants - including those initially in the placebo group - will have the opportunity to transition to an open-label extension (Part B), receiving three additional doses of NurOwn over another 24 weeks. The trial's primary efficacy endpoint will assess changes in ALSFRS-R scores from baseline to week 24, comparing disease progression between the NurOwn and placebo groups. The successful completion of Part A will position BrainStorm for a BLA submission, accelerating NurOwn's path to potential approval.

ALS remains a devastating disease with limited therapeutic options, and BrainStorm is committed to working closely with regulatory agencies, clinical investigators, and the ALS community to ensure the rapid and rigorous evaluation of NurOwn. The company will provide updates as the FDA review progresses.

About NurOwn®      
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 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 (NTFs). Autologous MSC-NTF cells are designed to effectively deliver multiple NTFs and immunomodulatory cytokines directly to the site of damage to elicit a desired biological effect and ultimately slow or stabilize disease progression.

About Brainstorm Cell Therapeutics Inc.              
Brainstorm Cell Therapeutics Inc. is a leading developer of innovative autologous adult stem cell therapeutics for debilitating neurodegenerative diseases. The Company holds the rights to clinical development and commercialization of the NurOwn® technology platform used to produce autologous MSC-NTF cells through an exclusive, worldwide licensing agreement. Autologous MSC-NTF cells have received Orphan Drug designation status from the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of amyotrophic lateral sclerosis (ALS). Brainstorm has completed a Phase 3 pivotal trial in ALS (NCT03280056); this trial investigated the safety and efficacy of repeat-administration of autologous MSC-NTF cells and was supported by a grant from the California Institute for Regenerative Medicine (CIRM CLIN2-0989). Brainstorm completed under an investigational new drug application a Phase 2 open-label multicenter trial (NCT03799718) of autologous MSC-NTF cells in progressive multiple sclerosis (MS) and was supported by a grant from the National MS Society (NMSS).
