NeuroSense Therapeutics Announces Positive Biomarker Data from ALS Phase 2b Clinical Trial
NeuroSense Therapeutics (NASDAQ: NRSN) has announced positive 12-month iron biomarker data from its Phase IIb PARADIGM study of PrimeC in ALS patients. The results show significant improvements in iron regulation, aligning with previously reported 36% slower disease progression and 43% improved survival rates. Key findings include a decrease in ferritin levels and an increase in transferrin levels, indicating alleviation of ALS pathology. Iron levels remained stable over the 12-month dosing period, with a mean difference of 4.536 µmol/L compared to the placebo group. These positive changes in iron metabolism correlate with better functionality and survival rates in patients treated with PrimeC. The company is preparing to share additional data with the FDA and is in discussions with potential development partners for marketing opportunities.

Insights
The 12-month biomarker data from NeuroSense's Phase IIb PARADIGM study for PrimeC in ALS patients is highly significant. The results demonstrate PrimeC's ability to regulate iron metabolism, a important factor in ALS pathology. Specifically:
- Ferritin levels decreased significantly, indicating reduced iron storage and potentially less oxidative stress.
- Transferrin levels increased, suggesting improved iron transport and regulation.
- Iron levels remained stable over the 12-month period, with a mean difference of
4.536 µmol/L (p=0.01) compared to the placebo-to-PrimeC transition group.
These biomarker changes align with the previously reported 36% slowing of disease progression and 43% improvement in survival rates. The data strongly supports PrimeC's mechanism of action and its potential as a transformative ALS therapy. However, it's important to note that while these results are promising, they still need to be confirmed in a larger Phase III trial to establish definitive efficacy and safety.
The endorsement from Dr. Merit Cudkowicz, a leading ALS researcher, adds credibility to these findings. Her support for proceeding to Phase III testing is a positive signal for the drug's potential. As NeuroSense prepares for FDA discussions and explores partnerships, investors should watch for announcements regarding the Phase III trial design and any potential collaborations, as these will be critical next steps in PrimeC's development journey.
This announcement presents a significant positive development for NeuroSense Therapeutics (NASDAQ: NRSN). The biomarker data from the Phase IIb trial provides strong support for PrimeC's efficacy in treating ALS, potentially positioning it as a breakthrough therapy in a market with treatment options. Key financial implications include:
- Market Potential: Given the improved survival rates and slowed disease progression, PrimeC could command premium pricing if approved, potentially generating substantial revenue for NeuroSense.
- Partnership Opportunities: The company's ongoing discussions with potential development partners could lead to lucrative collaboration agreements, providing additional funding and expertise for Phase III trials and commercialization.
- Investor Confidence: Positive clinical data typically boosts investor confidence, which could lead to increased stock valuation and easier access to capital if needed for future development stages.
However, investors should be cautious of potential risks:
- The need for a successful Phase III trial before potential FDA approval.
- Possible dilution if additional funding is required for the Phase III trial.
- Competition from other ALS therapies in development.
Overall, this news significantly de-risks NeuroSense's lead asset and enhances the company's value proposition. Investors should closely monitor upcoming FDA interactions and potential partnership announcements as these could be significant catalysts for the stock price.
12-month data demonstrated regulation of iron levels, which aligns with improved ALS survival and disease mitigation
Previous results showed PrimeC slowed disease progression by
ALS is a multifactorial disease in which iron and its related proteins play a critical role in its pathophysiology. These new results demonstrate the target engagement of PrimeC in iron regulation, which is linked to disease mitigation and improved survival. Iron metabolism is crucial in ALS pathology, with transferrin and ferritin being significant contributors to the progress of the disease. Iron accumulation in various brain regions of ALS patients has been linked to neuronal damage. Elevated ferritin levels, an indicator of iron storage, are consistently observed in ALS patients and are associated with reduced survival and potential oxidative stress. Conversely, lower levels of transferrin, the primary iron transport protein, contribute to iron dysregulation and disease progression.
The 12-month study results show a significant decrease in ferritin levels and a corresponding increase in transferrin levels, both indicating alleviation of the pathology. Iron levels remained stable over the 12-month dosing period, with a mean difference of 4.536 µmol/L (
These positive changes in iron metabolism align with improved clinical outcomes. Patients on PrimeC maintained better functionality and survival rates compared to those on placebo.
"The 12-month results from the PARADIGM Phase IIb study are encouraging, showing slowing of disease progression and improved survival outcomes," said Merit Cudkowicz, M.D., M.Sc., Chair of Neurology and Director of the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital. "This new analysis highlights PrimeC's ability to regulate the iron panel in people living with ALS, underscoring the drug's target engagement. These findings strongly support the proceeding to phase 3 testing of PrimeC in ALS."
The Company is currently compiling additional data to share with the FDA for discussion to determine the clinical and regulatory path forward. Additionally, the Company is continuing advanced discussions with several potential development partners to explore marketing opportunities following the potential completion and approval of PrimeC 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 people are diagnosed with ALS in the
About ALSFRS-R
Disease progression is measured by the ALS Functional Rating Scale-Revised (ALSFRS-R), which is the most widely used ALS tracking tool accepted by the FDA, utilized by neurologists treating ALS patients, in clinical trials, and by other regulators to determine disease progression. It tracks 12 changes in a person's physical abilities over time including functions such as: speech, walking, climbing stairs, dressing/hygiene, handwriting, turning in bed, cutting food, salivation, swallowing, and breathing. A single point change on the ALSFRS-R has a significant impact on ALS patients, such as the transition from independent feeding to requiring assistance or independent breathing to needing to use a machine ventilator.
About PARADIGM
PARADIGM is a prospective, multinational, randomized, double-blind, placebo-controlled Phase 2b (NCT05357950) clinical trial of PrimeC in ALS. The trial included 68 participants living with ALS in Canada, Italy, and Israel.
As previously reported, in the 6-month double-blind segment of the trial, the data showed clinically meaningful signs of efficacy with a
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 that contribute to motor neuron degeneration, inflammation, iron accumulation and impaired ribonucleic acid ("RNA") regulation to potentially inhibit the progression of ALS. NeuroSense completed a Phase 2a clinical trial which 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
