NeuroSense's PrimeC ALS Treatment Advances Toward Canadian Market with Conditional Regulatory Pathway

NeuroSense Therapeutics has achieved a significant regulatory milestone for its ALS treatment PrimeC as Health Canada has invited the company to a pre-New Drug Submission meeting to discuss a potential conditional regulatory pathway. This development represents a critical advancement in the company's strategy to bring PrimeC to Canadian patients suffering from amyotrophic lateral sclerosis, a progressive neurodegenerative disease with limited treatment options. The conditional pathway could enable earlier access to this promising therapy while comprehensive clinical data continues to be collected.

PrimeC is a novel extended-release oral formulation combining ciprofloxacin and celecoxib, two repurposed drugs that target multiple pathways implicated in ALS progression. Clinical evidence from the Phase 2b PARADIGM study demonstrated compelling results, showing a 36% reduction in disease progression and a 43% improvement in survival rates compared to placebo. These findings suggest PrimeC could represent a meaningful therapeutic advancement for ALS patients who currently face limited treatment options and poor prognosis.

The company has outlined an ambitious timeline targeting potential approval in Canada by the first half of 2026, with estimated peak annual revenue potential of $100-150 million in the Canadian market alone. This Canadian regulatory progress complements NeuroSense's global development strategy, which includes positive FDA feedback on its Phase 3 trial design and plans to initiate the pivotal study in mid-2025. The parallel regulatory pathways demonstrate the company's comprehensive approach to bringing PrimeC to patients worldwide.

The pharmaceutical industry has shown substantial interest in neurological innovations, as evidenced by significant licensing deals such as GlaxoSmithKline's $700 million upfront payment to Alector in 2021 and Biogen's $560 million partnership with Denali Therapeutics in 2020. These transactions highlight the substantial value potential of breakthrough neurological treatments. NeuroSense has similarly positioned itself for strategic partnerships, announcing in December 2024 a binding term sheet with a global pharmaceutical company that includes substantial upfront payments and funding for the Phase 3 program.

The advancement of PrimeC through Health Canada's conditional pathway represents more than just regulatory progress—it offers tangible hope for ALS patients and their families. The treatment's demonstrated ability to slow disease progression and improve survival addresses critical unmet medical needs in a condition where therapeutic options remain severely limited. As NeuroSense continues to navigate both Canadian and global regulatory landscapes, the potential for PrimeC to meaningfully impact ALS treatment paradigms remains a central focus of the company's development efforts and the broader neurological therapeutic community.
