BrainStorm Cell Therapeutics Announces Agreement with FDA on a Special Protocol Assessment (SPA) for Phase 3b Trial in ALS
- None.
- None.
The agreement between BrainStorm Cell Therapeutics and the FDA for a Special Protocol Assessment (SPA) is a significant milestone in the development of NurOwn for ALS treatment. The SPA provides a clear regulatory pathway for the Phase 3b trial, which is essential for potential marketing approval. The focus on ALS, a disease with limited treatment options, underscores the trial's potential to address a significant unmet medical need.
The primary efficacy endpoint, the change in the ALSFRS-R total score, is a standard measure of function in ALS clinical trials. The use of the combined assessment of function and survival (CAFS) as a primary inference metric is noteworthy, as it incorporates mortality data, providing a more comprehensive picture of treatment impact. The decision to include an open-label extension suggests confidence in the treatment's safety profile and offers continued access to therapy for participants, which may enhance patient recruitment and retention.
From a research perspective, the collection and analysis of CSF and blood biomarkers could yield valuable insights into the mechanisms of action of NurOwn and the pathophysiology of ALS. This data could inform future therapeutic strategies and enhance our understanding of neurodegenerative diseases.
The biotech industry often hinges on the outcomes of clinical trials and regulatory milestones, making the SPA for BrainStorm's NurOwn a pivotal event. The focus on enrolling patients earlier in the disease progression is strategic, as interventions in neurodegenerative diseases tend to be more effective at earlier stages. This could potentially lead to more pronounced treatment effects and a higher likelihood of demonstrating efficacy.
Investors will be closely monitoring the execution of the Phase 3b trial, as the results will have a direct impact on the company's valuation. The trial's design, which includes a double-blind, placebo-controlled period followed by an open-label extension, is robust and aligns with industry standards for pivotal studies. However, the trial's success is not guaranteed and the inherent risks of drug development must be considered.
BrainStorm's proactive engagement with neurologists, scientists and the ALS community in designing the trial may enhance the study's relevance and feasibility. The company's readiness to commence the trial in 2024 indicates a well-organized clinical development strategy, which is often looked upon favorably by investors.
For investors, the SPA agreement represents a de-risking event for BrainStorm, as it suggests a higher probability of trial success and potential FDA approval. The agreement may lead to increased investor confidence and could be a catalyst for stock price appreciation. However, the financial implications of conducting a Phase 3b trial are substantial and the company's financial health and ability to secure funding for the trial and potential commercialization should be scrutinized.
The impact on the stock market will depend on investor perception of the trial's likelihood of success and the market potential for ALS treatments. The anticipated commencement of the trial in 2024 means that any potential revenue from NurOwn is still several years away. Investors should consider the long-term nature of this investment and the various milestones that will need to be achieved before NurOwn can generate revenue.
It is also important to monitor the competitive landscape, as other companies may be developing treatments for ALS that could affect NurOwn's market potential. The financial health of BrainStorm, including its cash runway and funding strategy for the trial, will be key determinants of its ability to capitalize on this opportunity.

The SPA agreement with the FDA validates the clinical trial protocol and statistical analysis of the planned Phase 3b trial of NurOwn, demonstrating their adequacy for addressing objectives that support a future BLA (Biologics License Application) in ALS.
"We are pleased to have reached an agreement with the FDA on key elements of the Phase 3b trial design that provides a potential path forward towards obtaining regulatory approval," said Chaim Lebovits, President and Chief Executive Officer of BrainStorm. "We believe that having this SPA in place will help de-risk certain regulatory aspects of the NurOwn clinical program. BrainStorm's ultimate goal is to provide a new treatment option that can help patients afflicted with ALS, and we believe that the SPA potentially brings us one step closer to this goal. We appreciate the Agency's engagement and guidance during the SPA process and look forward to moving forward with the study."
BrainStorm anticipates commencement of the Phase 3b study in 2024, after reviewing the protocol with investigators, securing study site Institutional Review Board approvals, and engaging with appropriate members of the ALS community.
Stacy Lindborg, Co-CEO of BrainStorm, commented, "We have worked with leading neurologists, scientists, and members of the ALS community to create a robust study designed to evaluate the effectiveness and safety of NurOwn. This trial builds on valuable insights from our earlier studies and will enroll people living with ALS who are earlier in the course of their disease. Based on the evidence generated on NurOwn to date, we have a trial that we're optimistic will be positive. Over the past year, we've assembled an excellent team in clinical development that is highly qualified to execute this trial with excellence. We've been parallel processing to enable us to deliver the first dose in the trial in 2024, and we're anxious to get started."
The Phase 3b trial (Study BCT-006-US) will be a two-part, multicenter, study designed to assess the efficacy and safety of NurOwn in patients with ALS. The entry criteria will enroll participants earlier in the course of their disease, having the onset of ALS symptoms, including limb weakness, within the prior 24 months, all ALSFRS-R items 2 at Screening, and upright slow vital capacity >=
Part-A is a double blind, placebo-controlled period of 24 weeks duration. Up to approximately 200 patients are planned to be enrolled and randomized 1:1 to NurOwn or placebo treatment groups. There will be a screening period of six to nine weeks, during which eligible participants will undergo a single bone marrow aspiration procedure to procure the mesenchymal stem cells (MSCs) that will be used to manufacture each participant's NurOwn treatment for the duration of the trial. Patients will then be randomized 1:1 and treated with NurOwn or placebo via three repeated intrathecal injections, once every eight weeks. All eligible patients who complete Part-A will have the option of entering Part-B, open-label extension period of 24 weeks duration, where all participants will receive three repeated intrathecal injections of NurOwn, once every eight weeks.
The primary efficacy endpoint is the change in the Revised Amyotrophic Lateral Sclerosis Functional Rating (ALSFRS-R) total score from baseline to Week 24. Primary inference from the trial will be based on a p-value from the combined assessment of function and survival (CAFS) to account for mortality observed in the trial. Cerebrospinal Fluid (CSF) and blood samples will be collected for analysis of biomarkers of neuroinflammation, neurodegeneration, and neuroprotection. An independent Data Monitoring Committee (DMC) will monitor the safety of the trial participants.
Special Protocol Assessment
A Special Protocol Assessment (SPA) is a process in which drug developers may ask to meet with the FDA to reach an agreement on the design and size of certain clinical trials to determine if they adequately address scientific and regulatory requirements for a study that could support marketing approval. A SPA agreement indicates concurrence by FDA with the adequacy and acceptability of specific critical elements of overall protocol design for a study intended to support a future marketing application. These elements are critical to ensuring that the trial conducted under the protocol can be considered an adequate and well-controlled study that can support marketing approval. Feedback on these issues provides the greatest benefit to companies in planning late-phase development strategy. A SPA agreement does not indicate FDA concurrence on every protocol detail.
