NeuroSense Granted South Korean Patent Covering PrimeC Composition for ALS

CAMBRIDGE, Mass., June 11, 2026 /PRNewswire/ -- NeuroSense Therapeutics Ltd. (Nasdaq: NRSN) (“NeuroSense”  or the “Company”), a late-clinical stage biotechnology company developing novel treatments for severe neurodegenerative diseases, today announced that the Korean Intellectual Property Office (KIPO) has issued Korean Patent Number 10-2969898 covering the composition of PrimeC, the Company’s lead drug candidate for the treatment of amyotrophic lateral sclerosis (ALS).

The granted patent claims cover key aspects of PrimeC, including its proprietary tablet formulation, manufacturing process, pharmacokinetic characteristics, and pharmaceutical use for the treatment of ALS.

The patent is expected to provide patent protection for such aspects of PrimeC in South Korea through 2042.

“This patent grant further strengthens our growing global intellectual property estate surrounding PrimeC,” said Alon Ben-Noon, Chief Executive Officer of NeuroSense. “South Korea is an important pharmaceutical market, and this milestone reflects the continued recognition of the novelty and proprietary nature of PrimeC as we advance toward Phase 3 development.”

The South Korean patent grant follows patent grants received in other major jurisdictions, further expanding NeuroSense’s global intellectual property portfolio and supporting the long-term development and commercialization strategy for PrimeC.

PrimeC is a novel oral therapy designed to simultaneously target multiple biological mechanisms associated with ALS progression, including neuroinflammation, oxidative stress and dysregulated iron metabolism.

NeuroSense previously reported compelling results from its Phase 2b PARADIGM study, including meaningful slowing of disease progression, significant biological activity across multiple ALS-related biomarkers, including microRNAs, and long-term data demonstrating a meaningful survival benefit. The Company has received clearance from the U.S. Food and Drug Administration (FDA) to initiate its pivotal Phase 3 PARAGON study in ALS.

About NeuroSense

NeuroSense Therapeutics is a late-clinical stage biotechnology company developing novel treatments for severe neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and Alzheimer’s disease. The Company’s lead product candidate, PrimeC, is a novel oral therapy designed to target multiple key biological pathways underlying disease progression, including neuroinflammation, oxidative stress and dysregulated iron metabolism.

NeuroSense has generated compelling clinical data from its Phase 2b PARADIGM study in ALS, demonstrating meaningful slowing of disease progression. The Company also reported significant biological activity across multiple biomarkers associated with ALS, including microRNAs, supporting PrimeC’s multi-target mechanism of action. Notably, long-term follow-up data indicated a meaningful survival benefit, representing a potentially important advancement in the treatment of ALS.

NeuroSense has received clearance from the U.S. Food and Drug Administration (FDA) to initiate a pivotal Phase 3 clinical trial (PARAGON) in ALS, which is expected to enroll approximately 300 participants, primarily in the United States.

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 and AD, that contribute to neuron degeneration, inflammation, iron accumulation and impaired ribonucleic acid (“RNA”) regulation to potentially inhibit the progression of ALS and AD.

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.
