BrainStorm Cell Therapeutics Announces peer reviewed publication of NurOwn’s Phase 3 Study for ALS in Muscle and Nerve – BioSpace

NEW YORK, Dec. 13, 2021 /PRNewswire/ --BrainStorm Cell Therapeutics Inc. (NASDAQ: BCLI), a leading developer of cellular therapies for neurodegenerative diseases, today announced the peer reviewed publication of Phase 3 clinical data in Muscle and Nerve. The paper, entitled "A Randomized Placebo-Controlled Phase 3 Study of Mesenchymal Stem Cells Induced to Secrete High Levels of Neurotrophic Factors in Amyotrophic Lateral Sclerosis," can be found here.

Data from the paper are from a randomized, double-blind, placebo-controlled, Phase 3 trial evaluating the safety and efficacy of repeat doses of NurOwn in study participants. Although previously announced results showed the trial did not reach statistical significance on the primary or secondary endpoints, pre-specified and post hoc analyses show a NurOwn-induced treatment effect across both primary and secondary efficacy outcomes in those with less advanced disease.

"I am thankful for all the participants, faculty and staff at the six trial sites who all worked together to ensure the quality and rigor of this study," said Merit Cudkowicz, MD, MSc, Chief of Neurology Massachusetts General Hospital, Julieanne Dorn Professor of Neurology Harvard Medical School, Director Sean M. Healey & AMG Center for ALS at Mass General Hospital, and the study's lead author. "There are both biological and clinical signals of a treatment effect as a community, we must review these carefully. Understanding how to use biomarkers to tailor treatments, like NurOwn, is an essential new direction in ALS therapy development."

"Having these data peer reviewed and published in such a prestigious journal is an important milestone in the NurOwn development program, providing us with the ability to allow full transparency into the trial results and gain external validation from a journal devoted to publishing the most important findings on neuromuscular disorders and treatment options," said Chaim Lebovits, Chief Executive Officer, Brainstorm Cell Therapeutics. "When viewed in totality, we believe the trial's data provide evidence of NurOwn's effectiveness in driving meaningful clinical benefit for ALS patients with less advanced disease. We look forward to discussing these findings with regulators and remain fully committed to pursuing the best and most expeditious path forward to bring NurOwn to patients."

Key data and conclusions from the paper include:

Demographics:

Efficacy:

Biomarkers:

Safety:

NurOwn was well tolerated in the trial with no clinically significant differences in safety assessments observed between treatment groups.

Stacy R. Lindborg, PhD, Executive Vice President and Chief Development Officer, Brainstorm Cell Therapeutics, and co-author of the paper commented, "The publication provides a transparent view into this important NurOwn Phase 3 trial suggesting a meaningful clinical impact with NurOwn. The magnitude of the treatment effect in patients with less severe disease show that NurOwn is providing a robust and clinically meaningful benefit in this population. These benefits may also extend to additional patients, as pre-specified and post hoc analyses indicate that limitations in ALSFRS-R may have led to a floor effect that masked NurOwn-induced changes in patients with severe disease. This belief is further supported by biomarker data showing that NurOwn treatment led to significant, robust, and sustained changes across multiple pathways linked to ALS progression. We believe that collectively, these results demonstrate the potential of NurOwn to address the unmet needs of ALS patients and show that the future is bright for this differentiated cellular therapy."

Study Design

The Phase 3 NurOwn trial was a multi-center, placebo-controlled, randomized, double-blind trialdesigned to evaluate the safety and efficacy of repeat doses of NurOwn in 189 ALS patients. It was conducted at six centers of excellence:University of California Irvine(Dr.Namita Goyal);Cedars-Sinai Medical Center(Dr.Matthew Burford, Dr. Robert Baloh);California Pacific Medical Center(Prof.Robert Miller, Dr. Jonathan Katz);MassachusettsGeneral Hospital(Prof. Merit Cudkowicz, Dr.James Berry);University of Massachusetts Medical School(Prof.Robert Brown) andMayo Clinic(Prof.Anthony Windebank, Dr.Nathan Staff). Potential participants with ALS were screened during an 18-week run-in period and those who were rapid progressors (defined as patients with at least a 3-point decrease in ALSFRS-R score during the run-in period) were randomized 1:1 to receive three intrathecal injections (8 weeks between each injection) of NurOwn or placebo. Participants were followed for 28 weeks after treatment. The primary endpoints of the trial were safety assessments and a responder analysis of the rate of decline in ALSFRS-R score over 28 weeks, where response was defined as participants with a 1.25 points/month improvement in the post-treatment versus pre-treatment slope in ALSFRS-R at 28 weeks following the first treatment.Secondary endpoints included the percentage of patients with disease progression halted or improved, ALSFRS-R change from baseline, combined analysis of function and survival, slow vital capacity, tracheostomy-free survival, overall survival and cerebrospinal fluid biomarker measurements.

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 NurOwntechnology 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).
