Tonix Enrolls First Participant for PTSD Treatment Trial

Tonix Pharmaceuticals (NASDAQ:TNXP) has enrolled the first participant for a Phase 3 study of its post-traumatic stress disorder treatment TNX-102 SL.
As quoted in the press release:

“Enrolling the first participant in the HONOR study is an important event not only to Tonix, but potentially to millions who suffer worldwide from both civilian and military-related PTSD,” said Seth Lederman, M.D., Tonix’s president and chief executive officer. “The HONOR study is designed to confirm the clinical benefit of TNX-102 SL to improve PTSD symptoms across several measures as demonstrated in our Phase 2 AtEase study in military-related PTSD.”
About TNX-102 SL
TNX-102 SL is an investigational new drug and has not been approved for any indication.  It is a small, rapidly-disintegrating sublingual tablet containing 2.8 mg of cyclobenzaprine HCl for bedtime use. TNX-102 SL is a proprietary, Protectic™ protective eutectic formulation of cyclobenzaprine that allows for rapid systemic exposure and increased bioavailability through transmucosal delivery. Tonix is developing TNX-102 SL 5.6 mg (2 x 2.8 mg tablets), as a potential treatment for PTSD. In the Phase 2 AtEase study, TNX-102 SL 5.6 mg, taken sublingually at bedtime for 12 weeks demonstrated activity for the treatment of military-related PTSD compared to placebo, measured by a reduction in the Clinician Administered PTSD Scale for DSM-5, or CAPS-5 score. The most frequently reported adverse events were episodes of tongue numbness, which was generally transient and self-limited and related to the oral site of administration. Systemic adverse events included somnolence, dry mouth and sedation, which is similar to the known side effects of oral cyclobenzaprine. In December 2016, TNX-102 SL was granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) for the treatment of PTSD.
About the Phase 3 HONOR Study
HONOR is a Phase 3 randomized, double-blind, placebo-controlled trial evaluating the efficacy of TNX-102 SL 5.6 mg, in participants with military-related PTSD. The two-arm, adaptive design trial is designed to enroll 550 participants across approximately 35 U.S. sites. Participants in the HONOR study will be randomized to receive either TNX-102 SL 5.6 mg (2 x 2.8 mg tablets), or placebo, to be taken sublingually at bedtime daily for 12 weeks. The primary endpoint is the mean change from baseline, after 12 weeks, in the total CAPS-5 score compared between TNX-102 SL 5.6 mg, and placebo. In an End-of-Phase 2/Pre-Phase 3 meeting with Tonix, the FDA indicated its acceptance of Tonix’s proposed Phase 3 studies and the planned New Drug Application data package for the registration of TNX-102 SL for the treatment of PTSD.  Tonix has received FDA concurrence with the HONOR study design, including the proposal for an unblinded interim analysis (IA).
The HONOR study will have one unblinded IA by an independent data monitoring committee when the study has results from approximately 50% efficacy-evaluable participants, or approximately 275 participants, which is projected to occur in the first half of 2018.  If the IA results require continued enrollment, topline results from the 550-participants trial are expected to be available in the second half of 2018.

About Posttraumatic Stress Disorder
PTSD can develop from witnessing or experiencing a traumatic event in which there was the severe threat of, or actual occurrence of, grave physical harm or death. PTSD affects approximately 8.6 million Americans and is a chronic and severely debilitating condition in which patients re-experience the horrific traumas that resulted in the condition in the forms of intrusive memories, flashbacks, and nightmares. PTSD typically is characterized by disrupted sleep, anxiety, agitation, avoidance, emotional numbness and estrangement from family and friends, guilt or negative beliefs about self, and sometimes is associated with clinical depression and suicidal thinking. Individuals who suffer from PTSD usually have significant impairment in social functioning, occupational disability, and an overall poor quality of life. PTSD is sometimes associated with substance abuse and unpredictable violent or suicidal behaviors.  It is estimated that more than 19 percent of the 1.9 million U.S. veterans who were deployed to the recent conflicts in Iraq and Afghanistan suffer from PTSD.
