About this study

Official title: A Phase 3, Double-Blind, Randomized, Multicenter, Placebo-Controlled Study to Evaluate the Efficacy and Safety of TNX-102 SL in Participants With PTSD Taken Daily at Bedtime (Protocol No. TNX-CY-P302)

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Change From Baseline in the Total CAPS-5 Score

    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.

    Measured: Day 1, Week 12

Secondary outcomes (3)
  1. Clinical Global Impression of Severity (CGI-S)

    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).

    Measured: Day 1, Week 12

  2. Sheehan Disability Scale (SDS)

    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.

    Measured: Day 1, Week 12

  3. Patient-Reported Outcome Measurement Information System (PROMIS) Sleep Disturbance

    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.

    Measured: Day 1, Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing TNX-102 SL in people with PTSD, run by Tonix Pharmaceuticals, Inc. at 30 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 6 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 30 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Feb 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Change From Baseline in the Total CAPS-5 Score (time frame: Day 1, Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2025.
