CAMBRIDGE, Mass., April 7, 2025 /PRNewswire/ -- NeuroSense Therapeutics Ltd. (Nasdaq: NRSN) ("NeuroSense"), a clinical-stage biotechnology company developing novel treatments for severe neurodegenerative diseases, today reports its financial results for the year ended December 31, 2024 and provides a business update.

Business highlights from 2024 and to date

• PrimeC achieved primary and secondary clinical endpoints in PARADIGM Phase 2b study investigating PrimeC in ALS (n=68) with data showing the following:
  - PrimeC slowed disease progression (measured by ALSFRS-R) by approximately 33% after 18 months (p=0.007)
  - PrimeC reduced likelihood of mortality, hospitalization and respiratory support, resulting in an overall 58% improvement in survival rates. 
  - PrimeC slowed functional decline, especially speaking and swallowing functions. 
  - PrimeC demonstrated favorable safety and tolerability profile, achieving the study's primary endpoint. 
• Phase 3 study design for PrimeC for ALS aligned with FDA following Type C meeting. 
• Partnership discussions are continuing in order to advance PrimeC towards regulatory approval and eventual commercialization.  
• Plans to file for early commercialization for PrimeC in Canada, with an estimated potential market opportunity of $100m-$150m in peak annual revenues. 
• Key patent granted by U.S. Patent and Trademark Office (USPTO), extending the patent protection for the novel formulation of PrimeC until 2042.

"2024 was a year of significant clinical progress for NeuroSense," stated NeuroSense CEO, Alon Ben-Noon. "We successfully completed our Phase 2b study for PrimeC in ALS, with data showing transformative results in a neurodegenerative indication of immense medical need. The results conclude with PrimeC's disease-modifying potential and strongly support advancing PrimeC towards a Phase 3 study. With positive FDA feedback on the proposed study design, we are putting everything in place for the next stage of NeuroSense's growth, driven by PrimeC's continued clinical development."

Financial Results

Research and development expenses for the years ended December 31, 2024 and 2023 were $5.7 million and $7.3 million, respectively. The decrease of $1.6, or 21.9%, was mainly attributed to a decrease in our expenses to subcontractors and consultants and a decrease in share-based payment expense.

General and administrative expenses for the years ended December 31, 2024 and 2023 were $4.2 million and $4.8 million, respectively. The decrease of $0.6, or 12.5%, was mainly attributed to a decrease in share-based compensation and insurance costs and a decrease in salaries and social benefit expenses mainly due to decrease in the number of employees which were offset by an increase in professional services expenses.

As of December 31, 2024, NeuroSense had cash of approximately $3.4 million.

A summary of NeuroSense's consolidated financial results is included in the tables below.

About ALS
Amyotrophic lateral sclerosis ("ALS") is an incurable neurodegenerative disease that causes complete paralysis and death within 2-5 years from diagnosis. Every year, more than 5,000 people are diagnosed with ALS in the U.S. alone, with an annual disease burden of $1 billion. The number of people living with ALS is expected to grow by 24% by 2040 in the U.S. and EU.

About PrimeC
PrimeC, NeuroSense's lead drug candidate, is a novel extended-release oral formulation composed of a unique fixed-dose combination of two FDA-approved drugs: ciprofloxacin and celecoxib. PrimeC is designed to synergistically target several key mechanisms of ALS that contribute to motor neuron degeneration, inflammation, iron accumulation and impaired ribonucleic acid ("RNA") regulation to potentially inhibit the progression of ALS. NeuroSense completed a Phase 2a clinical trial which met its safety and efficacy endpoints including reducing functional and respiratory deterioration and statistically significant changes in ALS-related biological markers indicating PrimeC's biological activity. PrimeC was granted Orphan Drug Designation by the U.S. Food and Drug Administration and the European Medicines Agency.

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.
