NeuroSense Therapeutics Unveils Groundbreaking ALS Treatment Data from Phase 2b Trial

NeuroSense Therapeutics, Ltd. (NASDAQ: NRSN), an innovator in biotechnology, has announced pivotal discoveries from its Phase 2b PARADIGM trial. This clinical trial focuses on PrimeC, a novel therapy aimed at treating amyotrophic lateral sclerosis (ALS), a devastating neurodegenerative disease. Newly published data presented significant findings regarding the impact of microRNA (miRNA) modulation, shedding light on PrimeC's potential to change the disease's course.

At the recently conducted 77th Annual American Academy of Neurology (AAN) Meeting in San Diego, the significance of these findings was underscored by Jeffrey Rosenfeld, M.D., Ph.D., a neurology professor at Loma Linda University. Rosenfeld reported that the statistical analysis reveals strong support for PrimeC's ability to alter miRNA, linked closely to ALS progression and pathology.

Key Insights Revealed

The results from the trial indicate substantial progress in comprehending how PrimeC acts within the biological framework of ALS:

1. Downregulation of Key miRNAs: Patients undergoing treatment with PrimeC showcased a consistent decrease in 161 unique mature miRNAs throughout the trial. This finding was particularly striking when compared to the placebo group, which exhibited no noteworthy changes. This emphasizes PrimeC's targeted biological impact.

2. Correlation with Clinical Outcomes: Crucially, the downregulation of miRNAs such as miR-199 and miR-181—both known for their roles in ALS pathology—reinforces the therapy's clinical relevance. These miRNAs are associated with adverse outcomes such as neuroinflammation and higher mortality rates, thus their reduction aligns with the observed clinical benefits of PrimeC, including a 33% slowdown in disease progression and improved survival by 58%.

CEO Alon Ben-Noon expressed enthusiasm regarding these findings, stating, "We are thrilled with the outcomes from the PARADIGM trial. These results not only validate PrimeC’s approach but also its potential as a transformative therapeutic agent for ALS patients."

Research Collaboration and Future Directions

The groundwork for this compelling study was laid in collaboration with Prof. Noam Shomron from Tel Aviv University's Faculty of Medical and Health Sciences, a recognized authority in microRNA research. The partnership highlights the importance of cross-institutional collaboration in advancing biomedical research, particularly treatment developments for severe conditions like ALS.

Moving forward, NeuroSense is committed to delving deeper into the mechanistic understanding of PrimeC, with a focus on miRNA-based biomarkers that could provide insights into treatment response. This is a critical step in their goal to advance PrimeC for broader therapeutic implications beyond ALS, potentially addressing various neurodegenerative diseases.

Understanding ALS and MicroRNAs

ALS, often referred to as Lou Gehrig’s disease, presents a dire prognosis for those diagnosed, with paralysis often occurring within a few years. Each year in the U.S., over 5,000 new cases arise, contributing to an annual healthcare burden of $1 billion. Over the next two decades, the prevalence of ALS is anticipated to rise significantly.

MicroRNAs are essential regulators that dictate gene expression within cells. Their misregulation is thought to play a crucial role in the progression of neurodegenerative diseases, including ALS. Understanding how therapies like PrimeC interact with these molecular processes could pave the way for groundbreaking treatments.

About PrimeC

PrimeC, NeuroSense's primary drug candidate, is a specialized extended-release formula combining two existing FDA-approved drugs, ciprofloxacin and celecoxib. This innovative strategy targets multiple mechanisms within ALS pathology, aiming to mitigate motor neuron degeneration, reduce inflammation, and correct ribonucleic acid regulation.

The advancements observed in the Phase 2a clinical trials, which demonstrated safety and efficacy in halting disease progression, set the stage for broader applications of PrimeC in treating neurodegenerative diseases. Notably, PrimeC has received Orphan Drug Designation from both the FDA and the European Medicines Agency, underlining its potential significance.

As NeuroSense Therapeutics continues to move forward with PrimeC’s development, the burgeoning insights from the PARADIGM trial provide a substantial basis for further exploration and innovation in ALS treatment. With a focus on robust research and clinical validation, NeuroSense aims to address one of the most pressing medical needs of our time: effective treatment options for patients afflicted by debilitating neurodegenerative disorders.
