Brief summary
This is a 12-week, multicenter, randomized, double-blind, placebo-controlled, fixed-dose, parallel-group study that will investigate the efficacy and safety of two doses of TNX-102 SL -a sublingual formulation of cyclobenzaprine. Following successful screening and randomization, eligible subjects will return regularly to the study clinic for weekly or biweekly visits for assessments of efficacy and safety.

Primary
| Measure | Time frame | Description |
|---|---|---|
| The Mean Change From Baseline (Visit 2) in the Total CAPS-5 Score After 12 Weeks of Treatment Evaluated at Visit 9 (Week 12). | Day 1, Week 12 | The mean change from baseline (Visit 2) in the Total CAPS-5 score after 12 weeks of treatment evaluated at Visit 9 (Week 12). The primary efficacy comparison will be the change from baseline in total CAPS-5 score for the 2.8 mg treatment arm compared to placebo. CAPS-5 score ranges from 0-80 with lower scores indicating less severe PTSD symptoms. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Patients' Quality of Sleep Using the PROMIS Sleep Disturbance Scale After 12 Weeks of Treatment | Day 1, Week 12 | Change from baseline in patients' quality of sleep using the PROMIS (Patient -Reported Outcome Measurement Information System) Sleep Disturbance scale after 12 weeks of treatment comparing the 2.8 mg treatment arm to placebo. Raw scores are converted to T-scores using published conversion tables. Sleep Disturbance T-score ranges from 28.9 to 76.5. Lower scores indicate less sleep disturbance |
| Clinician Global Impression - Improvement Scale Responder Rate at Week 12 | Week 12 | Responder rates in CGI-I (Clinician Global Impression - Improvement Scale) after 12 weeks of treatment comparing the 2.8 mg treatment arm to placebo. Responder rate is defined as the number of patients scored as either a 1 or 2 on CGI-I at Week 12. The score ranges from 1 to 7 with the following anchors for each score:1=Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, 7=Very much worse |
| Mean Change From Baseline in Sheehan Disability Scale (SDS) Total Score | Day 1, Week 12 | Mean Change from Baseline in SDS Total Score at Week 12. 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. |

Outcome results
The Mean Change From Baseline (Visit 2) in the Total CAPS-5 Score After 12 Weeks of Treatment Evaluated at Visit 9 (Week 12).
The mean change from baseline (Visit 2) in the Total CAPS-5 score after 12 weeks of treatment evaluated at Visit 9 (Week 12). The primary efficacy comparison will be the change from baseline in total CAPS-5 score for the 2.8 mg treatment arm compared to placebo. CAPS-5 score ranges from 0-80 with lower scores indicating less severe PTSD symptoms.
Time frame: Day 1, Week 12
Population: Results are reported for patients in mITT population (included all patients who were randomized, had a baseline CAPS-5 and at least one post-baseline CAPS-5).~At Week 12 or last visit for subjects discontinuing early, values recorded more than 7 days after the last recorded dose are censored. Subjects that are lost to follow up or do not have a last dose date recorded have the day before their final visit imputed as the last dose date.
