A Phase 2, Multi-center, Multi-arm, Randomized, Placebo-controlled, Double-blind, Adaptive Platform Study to Evaluate the Safety, Tolerability, and Efficacy of Potential Pharmacotherapeutic Interventions in Active-Duty Service Members, Veterans, and Non-Veteran Civilians With PTSD
Global Coalition for Adaptive Research
Summary
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 available 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). The master protocol describes the default procedures and analyses for all cohorts; treatment-specific eligibility requirements, safety and efficacy procedures, or endpoints are described in the cohort-specific appendices and reflected in the intervention-specific clinicaltrials.gov records.
Description
The general structure of the M-PACT consists of a 30-day Screening Period, a 12-week Treatment Period, and a 4-week Safety Follow-up. The trial will include up to 5 open cohorts (it is possible for 1 of the cohorts to begin sooner than the others, as necessary). Importantly, the integration of multi-modal biomarker assessments within the M-PACT allows for defining future cohorts based on to be determined biomarker signatures in a multi stage approach. Initial testing in non biomarker defined cohorts will be referred to as "main stage" testing, while testing in biomarker-defined cohorts will oc…
