NeuroSense's PrimeC Demonstrates Outstanding Effect on ALS Survival in Innovative iPSC Model

• In collaboration with the University of Southern California's Ichida Stem Cell Lab, PrimeC was shown to significantly increase survival rate of induced motor neurons in an in vitro study utilizing induced pluripotent stem cells (iPSCs) generated from people living with ALS
• Results reinforce previous findings in multiple models 
• In a previous independent study carried out by Dr. Ichida, PrimeC performed among the best in improving motor neuron survival when compared to several other ALS drugs in development and two ALS FDA approved drugs

CAMBRIDGE, Mass., Oct. 4, 2023 /PRNewswire/ -- NeuroSense Therapeutics Ltd. (Nasdaq: NRSN) ("NeuroSense"), a company developing treatments for severe neurodegenerative diseases, today announced the results of a non-sponsored in vitro study of PrimeC in amyotrophic lateral sclerosis (ALS) conducted by Dr. Justin Ichida, PhD at the University of Southern California's (USC) Stem Cell Ichida Lab, part of the Eli and Edythe Broad CIRM Center for Regenerative Medicine and Stem Cell Research at USC.

Dr. Ichida's in vitro study used induced pluripotent stem cells (iPSCs) that were derived from blood samples of people living with ALS. The survival rate of induced motor neurons when administered with PrimeC in comparison to each of PrimeC's components, ciprofloxacin and celecoxib, alone was evaluated. PrimeC showed a significant beneficial effect relative to each of its components alone, demonstrating the synergistic effect of PrimeC and supporting the rationale of combining the two active components into NeuroSense's proprietary formulation. PrimeC attenuated ALS related pathology, as depicted by the increased survival rate. The PrimeC treated iPSCs had increased neuronal survival compared to ALS control cells, rendering their survival rate to be similar to healthy controls.

A previous study conducted independently by Dr. Ichida in iPSCs has already demonstrated NeuroSense's combination therapy performed among the best in improving motor neuron survival alongside several other ALS drugs in development and two FDA approved ALS drugs, Amylyx Pharmaceuticals' combination therapy, RELYVRIO, and Mitsubishi Tanabe's Radicava.

Dr. Ichida is the John Douglas French Alzheimer's Foundation Associate Professor of Stem Cell Biology and Regenerative Medicine and a New York Stem Cell Foundation–Robertson Investigator. He is widely recognized as being on the cutting edge of future treatments and cures for ALS and Alzheimer's disease, as well as the use of iPSCs, a state-of-the art in vitro cellular technique, in drug testing and development.

"At our lab, we screen thousands of compounds in search of one that may be effective in ALS, and we were very impressed by the data resulting from our iPCS in vitro study of PrimeC. We chose to evaluate PrimeC based on the growing body of clinical, pre-clinical, and biomarker data on its efficacy in ALS," Dr. Ichida stated. "As a candidate compound, NeuroSense's combination was among the best in improving motor neuron survival. Furthermore, in a follow-on study, where we explored specifically the synergistic effect of PrimeC combination relative to each one of its therapeutic agents, the results exceeded our expectations, as PrimeC increased the survival rate to the level of the healthy control and that got us very excited."

"Dr. Ichida has been described as being beyond the cutting edge in his field and we are honored that he and his lab chose to evaluate PrimeC in this non-sponsored study," stated NeuroSense Founder and CEO, Alon Ben Noon. "These results further bolster our confidence that PrimeC may offer a much-needed therapy for this debilitating disease which is ALS. We are proud that PrimeC is recognized as a leading ALS drug candidate by the top medical institutions in the world."

Dr. Shiran Zimri, VP R&D of NeuroSense added, "These findings present a new opportunity to potentially screen super responder patients using iPSCs, a non-invasive method which only requires a blood draw from the patient. Using this screening model may result in higher efficacy in people living with ALS who are most likely to benefit from PrimeC."

Dr. Zimri will be presenting these results at the 22nd Annual Northeast Amyotrophic Lateral Sclerosis (NEALS) Meeting which takes place October4-6, 2023 in Clearwater, Florida.

NeuroSense expects clinical topline results from PARADIGM, its Phase 2b study of PrimeC in the treatment of ALS in the fourth quarter of 2023.

About iPSCs in Drug Development

Cellular reprogramming, particularly the generation of induced pluripotent stem cells (iPSCs), has significant benefits for drug development, as they can be generated from patient-specific cells, such as skin or blood cells, and differentiated into various cell types. Deriving patient induced motor neurons (iMNs) from a patient's blood sample recapitulates the neurodegeneration involved in ALS, allowing for the creation of ALS in vitro models which ultimately provide a platform for drug screening and testing. Furthermore, cellular reprogramming enables high-throughput, personalized drug screening on patient derived nerve cells. Revolutionizing drug development, iPSCs provide accurate and more efficient models for disease research and drug discovery.

About NeuroSense

NeuroSense Therapeutics, Ltd. is a clinical-stage biotechnology company focused on discovering and developing treatments for patients suffering from debilitating neurodegenerative diseases. NeuroSense believes that these diseases, which include amyotrophic lateral sclerosis (ALS), Alzheimer's disease and Parkinson's disease, among others, represent one of the most significant unmet medical needs of our time, with limited effective therapeutic options available for patients to date. Due to the complexity of neurodegenerative diseases and based on strong scientific research on a large panel of related biomarkers, NeuroSense's strategy is to develop combined therapies targeting multiple pathways associated with these diseases.
