NeuroSense Completes Enrollment in Phase 2b ALS Clinical Trial

Home NeuroSense Completes Enrollment in Phase 2b ALS Clinical Trial
Written by Doug Hampton

The primary efficacy endpoint of PARADIGM, (NCT05357950), is the assessment of ALS-biomarkers to evaluate PrimeC and its biological activity. Secondary endpoints include the clinical outcome measures Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), Slow Vital Capacity (SVC), and overall survival, as well as safety and tolerability, in addition to a robust battery of additional biomarkers including neurofilaments.

Participants have the option to enroll in a 12-month OLE phase, during which they receive PrimeC. To date, 26 participants completed the 6-month double-blind phase of the trial and 25 of them chose to continue into the OLE. The results of the Phase 2b PARADIGM clinical trial will inform the design of a future pivotal Phase 3 clinical trial of PrimeC.

“It is highly encouraging that nearly all participants who completed the study have elected to continue in the OLE phase with the treatment of PrimeC,” stated Prof. Vivian Drory, Principal Investigator of the PARADIGM trial at Tel Aviv Sourasky Medical Center. “We look forward to seeing the topline data from this study which uses an optimized formulation of PrimeC. Based on the new formulation, we are aiming for efficacy and safety results that will meet and exceed the results achieved in the Phase 2a study which was conducted here at Sourasky Medical Center.”  

“PARADIGM is tracking 17 different outcome measures while the primary endpoint remains focused on biomarkers. This wealth of outcome data will not only be used to optimize the design of a future pivotal Phase 3 study for PrimeC, but we believe it will provide greater insight into the mechanisms of ALS for the scientific community as we advance toward a day when ALS will become a highly treatable disease,” stated NeuroSense’s Chief Medical Officer, Dr. Ferenc Tracik. 

“We are pleased to share this milestone for the PARADIGM clinical trial,” stated NeuroSense’s  CEO, Alon Ben-Noon. “We are grateful to the participants living with ALS, their families, and the study investigators for their commitment to the PARADIGM trial and for taking part in our mission to develop an effective therapy for ALS.”

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 patients are diagnosed with ALS in the U.S. alone, with an annual disease burden of $1 billion. The number of patients with ALS is expected to grow 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 amyotrophic lateral sclerosis (ALS) that contribute to motor neuron degeneration, inflammation, iron accumulation and impaired RNA regulation to potentially inhibit the progression of ALS. NeuroSense completed a Phase 2a clinical study which successfully 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 (FDA) and the European Medicines Agency (EMA).

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.
