NASDAQ: BCLI, a leading developer of adult stem cell therapies for neurodegenerative diseases, announced today that it has successfully completed its first milestone in developing an innovative exosome-based platform-technology for the treatment severe COVID-19 infection.COVID-19 induced pneumonia carries a high fatality rate and has been associated with acute respiratory distress syndrome ARDS. Currently, there is no effective treatment strategy to prevent or reverse ARDS, a type of respiratory failure associated with widespread inflammation and lung damage mediated by dysregulated cytokine production. Exosomes are nano-sized 30150 nm vesicles secreted by all cell types. Mesenchymal stem cells MSC derived exosomes have been suggested as a potential treatment for ARDS due to their ability to penetrate into deep tissues, effectively deliver bioactive molecules to target cells and mitigate the inflammatory response. MSC exosomes may be delivered intravenously or directly into the lung via intratracheal administration. Results from a study in a mouse model of lipopolysaccharide LPS-induced ARDS showed that intratracheal administration of NurOwn MSC-NTF cells derived exosomes resulted in a statistically significant improvement in multiple lung parameters. These included the clinically relevant factors: functional lung recovery, reduction in pro-inflammatory cytokines and most importantly, attenuation of lung damage. Moreover, MSC-NTF cell derived exosomes exhibited a superior effect when compared to treatment with exosomes derived from naïve mesenchymal stem cells MSC from the same donor. BrainStorm intends to accelerate submission of these important results to peer-reviewed medical journals. The preclinical experiment demonstrated a statistically significant reduction in lung disease severity score p0.03 based on the American Thoracic Society Documents, 2011; Matute-Bello et al., Am J Respir Cell Mol Biol 44;725-738, 2011 and vastly improved lung histology following intratracheal administration of NurOwn MSC-NTF exosomes compared to MSC exosomes.A graph accompanying this announcement is available at image accompanying this announcement is available at BrainStorm Cell Therapeutics has focused its clinical development on the application of the NurOwn technology platform to neurodegenerative disorders. Given these important pre-clinical results, the Company will revisit its strategy to determine if and when to proceed with a clinical trial in ARDS. Dr. Revital Aricha, VP of Research Development at BrainStorm, will discuss the results on the companys second quarter 2020 earnings call and corporate update, scheduled for Wednesday August 5th, at 8.00am ET.About NurOwnThe NurOwn technology platform autologous Mesenchymal stem cells, MSC-NTF cells represent 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 can 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 status designation 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 fully enrolled a Phase 3 pivotal trial in ALS NCT03280056, investigating repeat-administration of autologous MSC-NTF cells at six U.S. sites supported by a grant from the California Institute for Regenerative Medicine CIRM CLIN2-0989. The pivotal study is intended to support a filing for U.S. FDA approval of autologous MSC-NTF cells in ALS. BrainStorm is also conducting a U.S. FDA approved Phase 2 open-label multicenter trial in progressive multiple sclerosis MS. The Phase 2 study of autologous MSC-NTF cells in patients with progressive MS NCT03799718 started enrollment in March 2019.
