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.

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.

Outcome results

Primary

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.

Clinician Global Impression - Improvement Scale Responder Rate at 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

Time frame: 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). Patients without CGI-I data at Week 12 were considered as being non-responders.
