Intratracheal administration of exosomes extracted from MSC’s using NurOwn® technology resulted in statistically significant improvement in multiple lung parameters in a mouse model
BrainStorm will discuss results during Q2 corporate earnings call on Wednesday August 5
NEW YORK, July 23, 2020 (GLOBE NEWSWIRE) — BrainStorm Cell Therapeutics Inc. (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 (30–150 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
