ClinConnect Summary
This clinical trial, called the Department of Defense PTSD Adaptive Platform Trial, is studying new treatments for Post Traumatic Stress Disorder (PTSD). It's a Phase 2 study, which means it’s looking at how well these treatments work and if they are safe. Participants will be divided into different groups, with some receiving the actual medication and others receiving a placebo (a harmless substance with no active treatment). This setup helps researchers understand how effective each treatment is compared to no treatment at all.
To be eligible for this trial, participants need to be between 18 and 64 years old, must have been diagnosed with PTSD, and should have experienced a traumatic event more than three months before joining the study. Additionally, they need to be either currently serving or have served in the U.S. military. Participants can expect to undergo assessments, including questionnaires and possibly MRI scans, to monitor their progress throughout the trial. It's also important to note that participants must agree to use birth control during the study and for some time afterward. If you or someone you know is considering joining, it’s a valuable opportunity to help find new treatments for PTSD.

Hormonal contraceptives must have been started at least 2 months prior to the Baseline visit. In addition, agrees to no egg donation or harvesting for the duration of the study and for at least 30 days after the last dose of study treatment or as specified in the assigned cohort-specific appendices.

If in question, an Follicle-stimulating hormone (FSH) of \>40 U/mL, per central laboratory testing must be documented. Surgical sterility (hysterectomy, bilateral oophorectomy, or bilateral tubal ligation) must be documented.
- • 3. Females of reproductive potential must have a negative pregnancy test at the screening (serum) and baseline (urine) visits.
- • 4. For males, adequate birth control methods will be defined as the use of double barrier contraception (eg, male condom and diaphragm, male condom or diaphragm with spermicidal gel or foam). In addition, male participants must agree not to donate sperm for the duration of the study and for at least 30 days after the last dose of study treatment or as specified in the assigned cohort-specific appendices.
- • 5. Non-reproductive potential for males is defined as surgical sterility (ie, vasectomy) at least 3 months prior to baseline.
- • 8. Is able and willing to participate in study assessments and undergo blood draws.
- • 9. Is willing to undergo magnetic resonance imaging (MRI) eg, is not claustrophobic, has no contraindications to MRI.
- Exclusion Criteria: A participant who meets any of the following criteria will not be eligible to participate in this trial:
- • 1. Is pregnant or breastfeeding at the Screening or Baseline visits, or planning pregnancy during the study.
- 2. Is at risk for suicide based on any of the following:
- • 1. Had any suicidal ideation or behavior (including preparatory behavior) that required psychiatric hospitalization in the 3 months prior to screening.
- • 2. Had more than 2 actual suicide attempts within the last 3 years, not including interrupted or aborted attempts, preparatory acts or behaviors, or non-suicidal self-injurious behavior (as per C-SSRS response).
- • 3. Has any history of suicidal ideation and/or intent following initiation of a medication used for psychiatric symptoms or disorders.
- • 4. Has any history of suicide-related hospitalization following initiation of a medication used for psychiatric symptoms or disorders.
- • 3. Is taking any prohibited medication per Section 8.5.1 or cohort-specific restrictions (see cohort-specific appendices), is unable/unwilling to discontinue medications, or in the PI's judgement, cannot discontinue medications. Subjects must agree to a washout period of at least 14 days or 5 half-lives, whichever is longer, prior to the first dose of study intervention. Note, the half-life of the parent drug (not metabolites) should be used in this calculation.
- • 4. In the 3 months prior to the Baseline visit, has initiated or terminated individual or group PTSD specific psychotherapy (eg, Eye Movement Desensitization \& Reprocessing, Prolonged Exposure, Cognitive Processing Therapy, Stress Inoculation Training, Present Centered Therapy), or therapy is anticipated to conclude during the study. Completion of ≤2 sessions in the prior 3 months with no plans to continue is not exclusionary. Participants in stable trauma-focused or non-trauma focused therapy must agree to continue treatment for the duration of participation in the study.
- • 5. Has undergone or plans to undergo gender reassignment surgery. Note: participants who are currently undergoing stable hormone replacement therapy are eligible for inclusion in the study.
- • 6.
