Department of Defense PTSD Adaptive Platform Trial - Master Protocol

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a Phase 2 randomized, double-blinded, placebo-controlled study that will evaluate multiple potential pharmacotherapeutic interventions for PTSD utilizing an adaptive platform trial design. Participants are randomized among the multiple cohorts in the study and the resulting randomization enables sharing/pooling of control participants, where all interventions may be compared to a common control (placebo). This master protocol describes the default procedures and analyses for all cohorts; treatment-specific procedures will be described in the Master Protocol cohort-specific appendices. Individual cohorts may have additional eligibility requirements, safety and efficacy procedures, or endpoints, which will be described in corresponding intervention-specific clinicaltrials.gov records.

Agrees to consistently use an acceptable method of birth control as defined in Section 7.4.2 (required for both males and females who are of reproductive potential and sexually active with partners of the opposite sex) throughout the duration of participants' involvement in the study and for a minimum of 30 days after the last dose of study treatment or longer, as specified in the assigned cohort appendix (Table 3). 1. For females of reproductive potential, acceptable birth control methods are defined as: hormonal contraceptives, intrauterine device, or double barrier contraception (ie, male condom and diaphragm, male condom or diaphragm with spermicidal gel or foam). 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 appendix (Table 3). 2.

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 appendix (Table 3). 5.

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.	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.
