Following positive 6-month clinical outcomes from phase 2b (PARADIGM) clinical trial, Company expects additional biomarker and 12-month clinical in the near term CAMBRIDGE, Mass., June 24, 2024 /PRNewswire/ -- NeuroSense Therapeutics Ltd. (NASDAQ: NRSN) ("NeuroSense"), a company developing novel treatments for severe neurodegenerative diseases, today provides a corporate update following its recently announced analyses from its Phase 2b PARADIGM clinical trial, which demonstrated a statistically significant slowing of disease progression in high-risk ALS patients treated with PrimeC by 43% (p=0.02) as compared to placebo in the pre-specified per protocol (PP) population analysis after six months of treatment.[1] As previously indicated, the slowing of disease progression demonstrated by PrimeC versus placebo translates to a 5.04-point difference in the ALSFRS-R in favor of PrimeC (Confidence Interval: 0.862, 9.214; n=38). Corporate Highlights for the near term include: 12-month clinical results, including survival, expected in June 2024 FDA meeting anticipated in Q3 2024 Started preparations for Phase 3 clinical trial in the US, including protocol submission expected by year-end 2024 NeuroSense CEO Alon Ben-Noon states, "We are continuing to see additional results coming in from the PARADIGM trial and as they are being analyzed and verified, we intend to share them with shareholders. We anticipate sharing 12-month survival data, ALSFRS-R –as well as providing some additional biomarker data. These will include iron, ferritin and transferrin. We are looking forward to presenting target-engagement biomarkers alongside the clinical outcomes. In the meantime, we continue our discussions with several potential partners in order to drive our clinical programs forward efficiently." In addition, the Company hereby provides its Q1 2024 financial results: Research and development expenses for the three months ended March 31, 2024 and 2023 were $1.88 and $1.85 million, respectively. Research and development expenses remained at the same level primarily due to an increase in expenses to subcontractors and consultants as well as salaries and social benefits as a result of the progression of the Phase 2b ALS clinical study, which were fully offset by a decrease in share-based compensation expenses. NeuroSense expects research and development expenses to remain steady through the remainder of 2024 as a result of the open label extension of the Phase 2b ALS clinical study and the ongoing of the Phase 2 AD study. General and administrative expenses for the three months ended March 31, 2024 and 2023 were $1.11 and $1.14 million, respectively. General and administrative expenses remained at the same level primarily due to a decrease in salaries and social benefits, share-based compensation and insurance expenses, which were fully offset by increase in professional services. NeuroSense expects general and administrative expenses to remain steady through the remainder of 2024. Operating expenses for the three months ended March 31, 2024 and 2023 were $3 million due to the reasons described above. As of March 31, 2024, NeuroSense had cash of $0.74 million, which does not include gross proceeds of approximately $4.5 million from a financing that the Company completed in April 2024. As part of the transaction, the Company entered into a securities purchase agreement, pursuant to which the Company issued in a registered direct offering (i) 1,732,000 ordinary shares; (ii)pre-funded warrants to purchase 1,248,000 ordinary shares at an exercise price of $0.0001, exercisable at any time upon their issuance until exercised in full and (iii) warrants to purchase 2,980,000 ordinary shares at an exercise price of $1.50. Following the end of the first quarter of 2024, the Company determined to change its accounting method from IFRS to U.S. GAAP and accordingly has reissued its audited financial statements for all periods covered by its 2023 financial statements under U.S. GAAP. A copy of the reissued financial statements and accompanying financial data has been filed with the Securities and Exchange Commission on Form 6-K. The Company's unaudited consolidated financial results for the three months ended March 31, 2024 are presented in accordance with US GAAP Reporting Standards. A summary of NeuroSense's unaudited consolidated financial results is included in the tables below. Ben-Noon concluded, "We continue to build strong clinical evidence for PrimeC and are looking forward to upcoming announcements. Concurrently, we are working to safeguard our financial future and ability to continue our clinical activities so as to ensure that there is adequate cash on the balance sheet to complete these milestones. We plan to meet with the FDA in Q3 2024 to discuss the clinical path forward towards an NDA submission, which we believe will be a major inflection point for NeuroSense. The coming months hold tremendous potential, and we are optimistic about the outcomes and the future for NeuroSense Therapeutics." [1] High-risk patients, defined by the European Network for the Cure of ALS (ENCALS) Risk Factor as those with a higher risk for rapid disease progression, comprise approximately 50% of the total ALS population. 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 patients are diagnosed with ALS in the U.S. alone, with an annual disease burden of $1 billion. The number of patients with ALS is expected to grow by 24% by 2040 in the U.S. and EU. 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. 96% of the trial participants who completed the 6-month double-blind portion of the trial chose to receive treatment with PrimeC through a 12-month open label extension. Furthermore, to date all participants that completed the 18-month trial treatment duration, requested to continue PrimeC, which is provided to them in an Investigator Initiated Trial, not limited with time. As previously reported, top-line data from the 6-month double-blind segment of the trial showed clinically meaningful signs of efficacy with a 29% difference in ALSFRS-R (p=0.12) and a 13% difference in SVC (p=0.5), both in favor of PrimeC vs placebo in analysis of the intent to treat (ITT) population. These data include all 68 people living with ALS enrolled in Canada, Italy, and Israel, with the exclusion of one patient who was misdiagnosed. In the PP top-line analysis from PARADIGM, a statistically significant slowing of disease progression was observed with a 37.4% (p=0.03) difference in ALSFRS-R in favor of PrimeC vs placebo. Most patients enrolled in both the active and placebo arms of the trial were concurrently treated with Riluzole, the ALS standard of care medication, indicating PrimeC slowed disease progression well beyond the level afforded by the FDA approved ALS drug. 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 U.S. Food and Drug Administration and the European Medicines Agency.

According to the World Health Organization (WHO), millions of patients face treatment difficulties or even life-threatening conditions due to resistant bacterial infections each year. MRX-8 not only shows excellent safety and tolerability but also demonstrates strong antibacterial activity against multidrug-resistant Gram-negative. Bacteria ("MDR-GNB"), indicating significant clinical application potential. In China, the total number of days of antibiotic treatment for MDR-GNB infections increased from 43 million days in 2018 to 68.4 million days in 2023, with a compound annual growth rate of 10.3% during this period. SHANGHAI, June 6, 2024 /PRNewswire/ -- Recently, Shanghai MicuRx Pharmaceutical Co., Ltd. ("MicuRx", 688373.SH) successfully completed the Phase I clinical trial of its self-developed new injectable polymyxin antibacterial drug MRX-8 in China, achieving the expected goals. MRX-8 is primarily used to treat infections caused by multidrug-resistant Gram-negative bacteria. This significant milestone marks a crucial step towards MRX-8 becoming a safe and effective new antibacterial drug. China Phase I Clinical Trial Results The Phase I clinical trial in China was a randomized, double-blind, placebo-controlled study designed to evaluate the safety, tolerability, and pharmacokinetic characteristics of MRX-8 in healthy Chinese subjects. The trial included single ascending dose and multiple ascending dose components, demonstrating that MRX-8's drug exposure in the human body increases proportionally with the dose. The study demonstrated that at the expected clinical dose of 2.5 mg/kg once daily, MRX-8 can achieve ideal therapeutic effects against infections caused by multidrug-resistant Gram-negative bacteria. Moreover, MRX-8 exhibited good safety in healthy Chinese adults. Throughout the study, no subjects withdrew or terminated the trial due to adverse events, and no CTCAE Grade 3 or higher adverse events occurred. The most common adverse events were mild sensory reduction and decreased glomerular filtration rate, all of which were CTCAE Grade 1 and resolved without intervention. Only two subjects in the multiple dose group experienced CTCAE Grade 2 adverse events, both of which were injection site reactions.. The Study's Impact and Future Plans As one of the company's important new drug development product pipelines, the successful completion of the Phase I clinical trial of MRX-8 in China is of great significance. The study results indicate that MRX-8 exhibits good safety in healthy Chinese adults at the expected clinical dose, laying a solid foundation for its future clinical use.

This marks a crucial step forward for MRX-8 in becoming a safe and effective new antibacterial drug. The company will combine the results and data from both the US and China Phase I clinical trials to formulate the next steps in MRX-8's clinical development plan. The company will actively explore development pathways for different potential indications, aiming to make MRX-8 a new antibacterial drug with significant clinical value for treating multidrug-resistant Gram-negative bacterial infections, in order to meet the rapidly growing need for clinical treatment. The company is committed to creating maximum value for society and the company, driving MRX-8 towards market availability, and providing new hope for patients. About MRX-8 MRX-8 is a novel injectable polymyxin antibacterial drug independently developed by MicuRx Pharmaceuticals, primarily used to treat severe infections caused by multidrug-resistant Gram-negative bacteria. Traditional polymyxin drugs have limited clinical use due to their high risk of nephrotoxicity and neurotoxicity. MRX-8, through meticulous structural design, not only maintains or improves therapeutic efficacy, but also significantly reduces these toxic risks. Results from the Phase I clinical trial completed in the United States in 2022 showed that MRX-8 achieves ideal therapeutic effects against infections caused by multidrug-resistant Gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii. Multidrug-Resistant Gram-Negative Bacteria and Market Demand Gram-negative bacteria are resistant to multiple drugs and are increasingly resistant to most available antibiotics. Multidrug-resistant Gram-negative bacteria (MDR-GNB) are a specific class of Gram-negative bacteria whose multidrug resistance is defined as resistance to three or more commonly prescribed antibiotics (ceftazidime, ciprofloxacin, meropenem, gentamicin, ampicillin/sulbactam, or piperacillin/tazobactam). Infections caused by MDR-GNB have a mortality rate five times higher than infections caused by conventional Gram-negative bacteria. Globally, infections caused by multidrug-resistant Gram-negative bacteria have become a major public health challenge. According to the World Health Organization (WHO), millions of patients face treatment difficulties or even life-threatening conditions due to resistant bacterial infections each year. In hospitals and intensive care units, infections caused by resistant Gram-negative bacteria result in high mortality rates and significant treatment costs, posing substantial pressure on healthcare systems. In China, the total number of days of antibiotic treatment for MDR-GNB infections increased from 43 million days in 2018 to 68.4 million days in 2023, with a compound annual growth rate of 10.3%.[1] Currently, the market has limited options for effectively treating multidrug-resistant Gram-negative bacterial infections, and the severe side effects of traditional polymyxin drugs further restrict their clinical use. The development and clinical trial results of MRX-8 address this unmet market need. MRX-8 not only shows excellent safety and tolerability but also demonstrates strong antibacterial activity against multidrug-resistant Gram-negative bacteria, indicating significant clinical application potential.
