4 terms

tbi medical

"traumatic brain injury (TBI) and related central nervous system injuries"

Traumatic brain injury (TBI) is damage to the brain caused by a sudden external force — for example a blow, jolt, or penetration — that disrupts normal brain function. Investors watch TBI because it creates demand for treatments, medical devices, diagnostics and long-term care; breakthroughs, safety concerns or regulatory decisions in this area can change revenue prospects and valuation for companies working on TBI solutions, similar to how a rise in auto crashes increases demand for safety products and emergency care.

cte medical

"chronic traumatic encephalopathy (CTE)"

Chronic Traumatic Encephalopathy (CTE) is a progressive brain condition linked to repeated head impacts that can cause memory loss, mood changes and impaired thinking; it is most often confirmed after death. Think of it as long-term wear-and-tear on the brain’s wiring. Investors watch CTE because research, lawsuits, regulatory action or changing safety standards can create legal costs, liability, insurance exposure and reputational damage that affect a company’s finances and future sales.

als medical

"beyond ALS into an indication affecting millions worldwide"

Amyotrophic lateral sclerosis (ALS) is a progressive neurological disease that damages the nerve cells controlling muscles, gradually causing weakness, loss of movement and difficulty breathing — similar to the body’s wiring slowly failing. For investors, ALS matters because research progress, clinical trial results, regulatory approvals or setbacks can dramatically affect the value of companies developing treatments, patient-care markets and related healthcare services.

oxidative stress medical

"including neuroinflammation, oxidative stress and progressive neuronal damage"

Oxidative stress is a biological imbalance where damaging, unstable molecules overwhelm the body’s neutralizing defenses, similar to how rust forms when metal is exposed to oxygen and moisture. Investors should care because oxidative stress is linked to many diseases and aging processes, influencing demand for drugs, diagnostics, supplements, and healthcare spending, and it can affect the commercial value and regulatory outlook of related products.

• Patent application seeks protection for PrimeC use in concussion, blast-related brain injury and chronic traumatic encephalopathy (CTE)
• Positions PrimeC for potential expansion beyond ALS into an indication affecting millions worldwide, with no approved disease-modifying therapy
• Filing supports opportunities for research partnerships

CAMBRIDGE, Mass., Oct. 19, 2026 /PRNewswire/ -- NeuroSense Therapeutics Ltd. (NASDAQ: NRSN) ("NeuroSense" or the "Company"), a late-stage clinical biotechnology company developing treatments for neurodegenerative diseases, today announced that it has filed a patent application with the U.S. Patent and Trademark Office covering methods of treating traumatic brain injury (TBI) and related central nervous system injuries with the combination of ciprofloxacin and celecoxib, the active ingredients of PrimeC.

The application covers the treatment of a broad range of brain injuries, from concussion and mild TBI to moderate and severe TBI, including blast-related injury, as well as their long-term consequences, such as chronic traumatic encephalopathy (CTE). If granted, the patent is expected to provide protection through 2047, subject to any extensions.

Traumatic brain injury (TBI) represents a major global healthcare challenge, affecting millions of people each year. TBI can result from falls, motor vehicle accidents, sports-related injuries and military-related trauma, including blast exposure. Its consequences can extend well beyond the initial event, potentially causing persistent cognitive, physical and behavioral impairment, with substantial burdens on patients, caregivers and healthcare systems. Despite this significant unmet medical need, there are currently no approved disease-modifying therapies specifically targeting the secondary neurological injury associated with TBI.

Following the initial trauma, TBI can trigger complex biological processes, including neuroinflammation, oxidative stress and progressive neuronal damage. Certain mechanisms overlap with pathways implicated in neurodegenerative disorders.

The patent filing also supports NeuroSense's longer-term strategy of pursuing additional applications for PrimeC beyond its existing development programs. The Company views TBI as an opportunity to broaden PrimeC's commercial potential and build additional long-term value around its lead asset. While ALS remains NeuroSense's primary development priority, the Company is evaluating future TBI-focused research and development initiatives, through strategic collaborations, research grants and other non-dilutive funding opportunities.

"While ALS remains our primary focus, we believe PrimeC may have potential across a broader range of neurological conditions that share common underlying disease mechanisms," said Alon Ben-Noon, Chief Executive Officer of NeuroSense. "TBI is a particularly compelling area given the large affected population, the long-term consequences of brain injury and the lack of approved disease-modifying treatments. This filing strengthens our intellectual property position and creates a foundation for future research, partnerships and non-dilutive funding opportunities, while maintaining our focus on advancing our core ALS program. We look forward to sharing further updates as our clinical and strategic initiatives advance."

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 recently completed analysis of long-term follow-up data from its Phase 2b PARADIGM study in ALS, with results published in JAMA Neurology showing slower functional decline in participants who received PrimeC from study start than in those who initially received placebo. The Company also reported changes across multiple biomarkers associated with ALS, including microRNAs, consistent with PrimeC's multi-target mechanism of action.

NeuroSense has received clearance from the U.S. Food and Drug Administration (FDA) to initiate its pivotal Phase 3 clinical trial (PARAGON) in ALS, to be conducted primarily in the United States. The Company is working with FDA on an optimized design for the study.

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 target several key mechanisms that contribute to neuron degeneration, inflammation, iron accumulation and impaired ribonucleic acid ("RNA") regulation, with the potential to inhibit disease progression.

About ALS

Amyotrophic lateral sclerosis ("ALS") is an incurable neurodegenerative disease that causes progressive paralysis and, typically, death within 3 years of symptoms onset. 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.
