About TNX-102 SL and the Phase 3 HONOR Study

TNX-102 SL is a patented** sublingual formulation of low dose cyclobenzaprine that is in Phase 3 development for PTSD. In a Phase 2 study, TNX-102 SL 5.6 mg was found to be effective in treating military-related PTSD, and FDA has awarded TNX-102 SL Breakthrough Therapy designation. Tonix is currently conducting a Phase 3 HONOR study of TNX-102 SL in military-related PTSD in the United States. HONOR is a 12-week randomized, double-blind, placebo-controlled trial evaluating the efficacy of TNX-102 SL 5.6 mg in participants with military-related PTSD. This two-arm, adaptive-design trial is targeting to enroll up to approximately 550 participants across approximately 35 clinical sites. An unblinded interim analysis will be conducted once the study has accumulated efficacy results from approximately 275 randomized participants. In a recent Cross-disciplinary Breakthrough meeting, FDA confirmed that a single-study NDA approval could be possible if the topline data from HONOR is statistically very persuasive. Additional details of HONOR are available at or

** The U.S. Patent and Trademark Office has issued a patent (U.S. Patent No. 9,636,408) protecting the composition and manufacture of the unique formulation that characterizes TNX-102 SL. This patent is expected to provide Tonix with U.S. market exclusivity until 2034 upon NDA approval.
