Safety and Efficacy Study of TNX-102 SL in Subjects With Military-Related PTSD and Related Conditions (AtEase)

May 24, 2024 updated by: Tonix Pharmaceuticals, Inc.

A Phase 2, Double-Blind, Randomized, Multicenter, Placebo-Controlled Study to Evaluate the Efficacy and Safety of TNX-102 SL Taken at Bedtime in Subjects With Military-Related PTSD and Related Conditions (Protocol No. TNX-CY-P201) -"AtEase STUDY"

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Mean Change From Baseline (Visit 2) in the Total CAPS-5 Score After 12 Weeks of Treatment Evaluated at Visit 9 (Week 12).
Time Frame: 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.
Day 1, Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Patients' Quality of Sleep Using the PROMIS Sleep Disturbance Scale After 12 Weeks of Treatment
Time Frame: 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
Day 1, Week 12
Clinician Global Impression - Improvement Scale Responder Rate at Week 12
Time Frame: 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
Week 12
Mean Change From Baseline in Sheehan Disability Scale (SDS) Total Score
Time Frame: 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.
Day 1, Week 12
