Tonix Pharmaceuticals Reports Promising Phase 3 Results for Fibromyalgia Treatment

Tonix Pharmaceuticals Holding Corp. (NASDAQ: TNXP) has presented encouraging Phase 3 data for its sublingual cyclobenzaprine formulation, TNX-102 SL, at the 2025 Annual European Congress of Rheumatology (EULAR) in Barcelona. The RESILIENT Phase 3 trial results demonstrated statistically significant and sustained pain reduction over 14 weeks, alongside improved sleep and a favorable tolerability profile. This development is significant as TNX-102 SL could become the first new fibromyalgia therapy in 15 years, pending FDA approval, with a Prescription Drug User Fee Act (PDUFA) goal date set for Aug. 15, 2025.

The innovative design of TNX-102 SL, which bypasses first-pass liver metabolism, allows for higher nighttime cyclobenzaprine levels and reduced norcyclobenzaprine accumulation compared to oral formulations. This mechanism may enhance the drug's long-term efficacy and safety, offering hope to millions suffering from fibromyalgia, a condition characterized by chronic pain and sleep disturbances. The FDA has already granted Fast Track designation to TNX-102 SL, underscoring its potential to address an unmet medical need.

With fibromyalgia affecting an estimated 2-4% of the global population, the successful development and approval of TNX-102 SL could significantly impact the treatment landscape. The drug's ability to provide sustained pain relief and improve sleep quality without the drawbacks of current therapies positions it as a potentially transformative option for patients. Tonix Pharmaceuticals' progress with TNX-102 SL not only highlights the company's commitment to advancing pain management solutions but also represents a critical step forward in addressing the complex challenges of fibromyalgia treatment.
