Tonix Pharmaceuticals Presented Preclinical Data on Gastric Cancer Models at the American Association for Cancer Research (AACR) 2025 Annual Meeting

Core Insights - Tonix Pharmaceuticals is advancing TNX-1700, a combination therapy involving TFF2 and anti-PD1 antibody, showing potential in enhancing anti-tumor immune responses in gastric and colorectal cancers [1][2] - The company presented promising preclinical data at the AACR 2025 Annual Meeting, indicating that TFF2-mediated CXCR4 partial agonism is more effective than antagonism in reducing gastric cancer in animal models [1][2] Company Overview - Tonix Pharmaceuticals is a fully-integrated biopharmaceutical company with a focus on developing therapies for pain management, immunology, and infectious diseases [7] - The company is also working on TNX-102 SL for fibromyalgia, which has received Fast Track designation from the FDA, with a PDUFA goal date of August 15, 2025 [7] Research and Development - TNX-1700 is being developed under a license from Columbia University, with Dr. Timothy Wang as the inventor, who has demonstrated the protective role of TFF2 against cancer development [3] - The research indicates that TFF2 can suppress immunosuppressive neutrophils (PMN-MDSCs) and enhance the activation of CD8+ T cells, which are crucial for anti-tumor immunity [2][3] Clinical Implications - The combination of TFF2 and anti-PD1 therapy has shown promise in reducing immunosuppression in the tumor microenvironment, potentially leading to improved treatment outcomes for patients with gastric cancer [2] - The correlation between TFF2 levels and PMN-MDSCs in gastric cancer patients suggests a potential biomarker for treatment efficacy [2]
