Celecoxib

THURSDAY, June 27, 2024 -- PIK3CA mutational status may be beneficial for predicting response to addition of the cyclooxygenase 2 (COX-2) inhibitor celecoxib to standard adjuvant chemotherapy in stage III resected colon cancer, according to a study published online June 18 in the Journal of Clinical Oncology . Jonathan A. Nowak, M.D., Ph.D., from Brigham and Women's Hospital in Boston, and colleagues prospectively examined whether adding the COX-2 inhibitor celecoxib to standard adjuvant chemotherapy reduces the risk of recurrence and improves survival for patients with stage III resected colon cancer. Preplanned subgroup analysis was performed by PIK3CA mutational status. Of the 1,197 tumors with available whole-exome sequencing data, PIK3CA gain-of-function mutations were identified in 259. The researchers found that there was no significant improvement in disease-free survival (DFS) with celecoxib for all patients. On stratification by PIK3CA status, patients with gain-of-function mutations treated with celecoxib had significantly improved DFS (adjusted hazard ratio, 0.56 [95 percent confidence interval, 0.33 to 0.96]) compared with wildtype PIK3CA patients (adjusted hazard ratio, 0.89 [0.70 to 1.14]); the interaction was not significant. Patients with PIK3CA gain-of-function mutations had similarly improved overall survival (adjusted hazard ratio, 0.44 [0.22 to 0.85]) compared with wildtype patients (adjusted hazard ratio, 0.94 [0.68 to 1.30]). "These findings represent the first clinical trial results to validate observational studies that have associated adjuvant aspirin and other nonsteroidal anti-inflammatory drug use, including COX-2 inhibitors, with improved survival for patients with PIK3CA -mutant colorectal cancer," the authors write.

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. About NeuroSense NeuroSense Therapeutics, Ltd. is a clinical-stage biotechnology company focused on discovering and developing treatments for patients suffering from debilitating neurodegenerative diseases. NeuroSense believes that these diseases, which include amyotrophic lateral sclerosis (ALS), Alzheimer's disease and Parkinson's disease, among others, represent one of the most significant unmet medical needs of our time, with limited effective therapeutic options available for patients to date. Due to the complexity of neurodegenerative diseases and based on strong scientific research on a large panel of related biomarkers, NeuroSense's strategy is to develop combined therapies targeting multiple pathways associated with these diseases.
