Brief summary
This is a 12-week, multicenter, randomized, double-blind, placebo-controlled, fixed-dose study that will investigate the efficacy and safety of TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) - a sublingual formulation of cyclobenzaprine. Following successful screening and randomization, eligible patients will have a telephonic visit at week 2 and then return regularly to the study clinic for monthly visits for assessments of efficacy and safety.
Interventions
Patients will take 2 tablets of randomly assigned study drug sublingually starting on Day 1 for 12 weeks

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Change From Baseline in the Total CAPS-5 Score | Day 1, Week 12 | The primary efficacy endpoint is the mean change from baseline (Day 1) in the total CAPS-5 score after 12 weeks of treatment. The CAPS-5 is an updated and validated version of a semi-structured interview that has been designed to assess the essential features of PTSD as defined by the DSM-5. The total score ranges from 0 to 80 with higher scores indicating more severe PTSD symptoms. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Global Impression of Severity (CGI-S) | Day 1, Week 12 | Change from baseline (Day 1) in CGI-S score at Week 12. CGI-S range from 1 (Normal, not ill at all) to 7 (Among the most extremely ill patients). |
| Sheehan Disability Scale (SDS) | Day 1, Week 12 | Change from baseline in Sheehan Disability Scale (SDS) total score after 12 weeks of treatment comparing the 5.6 mg treatment arm to placebo. The SDS is a self-report questionnaire that was designed to assess the participant's view of the degree to which symptoms have disrupted work/school, social life/leisure activities, and family life/home responsibilities during the previous two weeks. Score ranges from 0 to 30. A score of 0 means the patient is unimpaired, and a score of 30 means the patient is highly impaired. |
| Patient-Reported Outcome Measurement Information System (PROMIS) Sleep Disturbance | Day 1, Week 12 | Change from baseline (Day 1) to Week 12 in the PROMIS Sleep Disturbance scale. The PROMIS Sleep disturbance short form 8a consists of 8 questions on a 5-point scale (1 to 5) where a higher score indicates a worse outcome. The total score is reported on a range of 8 to 40. Raw scores are converted to T-scores based on US population with score of 50 as average with a standard deviation of 10. |
