NeuroSense Therapeutics Advances Toward Canadian Fast-Track Approval for ALS Drug PrimeC

NeuroSense Therapeutics (NASDAQ: NRSN) has reached a significant milestone in its quest to bring PrimeC, its lead ALS drug candidate, to market, following a constructive pre-submission meeting with Health Canada. This meeting explored the drug’s eligibility for Canada’s fast-track approval pathway, known as the Notice of Compliance with Conditions (NOC/c), potentially expediting PrimeC’s availability to Canadian ALS patients.

The positive outcome of this meeting not only paves the way for accelerated approval in Canada but also strengthens NeuroSense’s position in negotiations with a global pharmaceutical company. A binding term sheet signed in December 2024 outlines a partnership that includes full Phase 3 funding, upfront cash, milestone payments, and double-digit royalties, contingent on regulatory progress such as this.

PrimeC’s potential is underscored by compelling Phase 2b PARADIGM trial results, which demonstrated a 36% slowdown in ALS progression and a 43% improvement in survival rates. These findings are particularly significant in a therapeutic area with limited treatment options and where efficacy gains are rare. The Canadian market alone represents a substantial opportunity for NeuroSense, with estimated peak annual sales of $100–150 million.

Beyond the immediate financial implications, securing fast-track approval in Canada could serve as a strategic advantage for NeuroSense. It would enable the collection of real-world data and establish market presence ahead of potential approvals in the U.S. and Europe, further validating PrimeC’s efficacy and safety profile.

Investors and stakeholders are awaiting official meeting minutes from Health Canada, which will clarify PrimeC’s eligibility for the NOC/c pathway. A favorable decision could trigger the submission of a New Drug Submission (NDS) and the initiation of Phase 3 trials, marking a critical step toward commercialization.

NeuroSense’s progress with PrimeC represents a beacon of hope for ALS patients and a potential inflection point for the company. With validated clinical data, regulatory momentum, and a promising partnership on the horizon, the coming months could redefine NeuroSense’s trajectory and the ALS treatment landscape.
