January 12, 2025 updated by: Tonix Pharmaceuticals, Inc.

A 40-week Open-Label Extension Study to Evaluate TNX-102 SL 5.6 mg Taken Daily at Bedtime in Patients With PTSD

Evaluate the long-term safety of TNX-102 SL 5.6 mg taken daily at bedtime over an additional 40 weeks in patients with PTSD who have participated in a double-blind lead-in study and completed an initial 12-week open-label extension study (TNX-CY-P303).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open-label, extension trial designed to evaluate safety over 40 additional weeks of TNX-102 SL therapy taken daily at bedtime for the treatment of PTSD.

The study will consist of 5 in-clinic study visits, including Baseline Visit 1 (Day 0, which is anticipated to be the same visit as the last visit of the 12-week open-label extension study TNX-CY-P303), followed by in-clinic visits after 7, 16, 28 and 40 weeks of open-label treatment.

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. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • The patient has completed a double-blind lead-in HONOR study and a 12-week open-label extension study P303 and is judged by the investigator as reasonably compliant, with at least 60% compliance with study medication usage (based on drug accountability).
  • The patient has provided written informed consent to participate in this extension study.
  • The patient met all prior inclusion and exclusion requirements for the double-blind lead-in HONOR study, or the site received medical monitor approval for the patient to remain in the lead-in study after the retrospective discovery of an entry violation that did not pose any threat to the patient's safety or well-being.
  • During the course of the lead-in HONOR study or 12-week open-label extension P303 study, the patient has had no intervening medical conditions including pregnancy, clinically significant increase in suicidal ideation (plan or intent) or significant worsening of depression, newly arising clinically significant abnormal laboratory tests, or any clinically significant, uncontrolled, or unstable medical or surgical condition that could affect the patient's ability to participate in the study or potentially compromise the patient's well-being during the study.
  • The patient does not require treatment with a potent (strong) cytochrome P450 subtype 3A4 (CYP3A4) inhibitor, or St. John's wort.
  • The patient is willing to refrain from use of all other formulations of cyclobenzaprine for the duration of the study.
  • The patient is willing to refrain from use of monoamine oxidase inhibitors for the duration of the study.
  • Female patients of childbearing potential continue to agree to practice one of the medically acceptable methods of birth control detailed in the lead-in study.

Exclusion Criteria:

  • There are no exclusion criteria for this study.

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
Incidence of Newly Emergent Adverse Events
Time Frame: 40 weeks
Evaluate the incidence of newly emergent adverse events over an additional 40 weeks of treatment with TNX-102 SL 5.6 mg in patients with PTSD who have participated in a double-blinded lead-in study. Adverse events will be coded using the latest version of the Medical Dictionary for Regulatory Activities (MedDRA) and will be summarized overall and by preferred term and system organ class. Serious AEs and AEs leading to discontinuation of study drug will also be summarized.
40 weeks

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
Evaluate the proportion of patients with a CGI-I score of "very much improved" or "much improved" of TNX-102 SL tablets taken daily at bedtime over an additional 40 weeks in patients with PTSD who have participated in a double-blinded lead-in study
Time Frame: Weeks 7, 16, 28, and 40
The CGI-I is a clinician-rated scale designed to assess overall clinical improvement (change) since baseline.
Weeks 7, 16, 28, and 40
