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
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.
Intervention B - Vilazodone will assess the safety and efficacy of vilzodone in participants with PTSD.
Please see NCT05422612 for information on the S-21-02 Master Protocol.
The general structure of this Adaptive Platform Trial (APT) consists of a 30-day Screening Period, a 12-week Platform Treatment Period, and a 4-week Safety Follow-up. The S-21-02 Platform Trial will evaluate the safety and efficacy of multiple investigational products for the treatment of PTSD (see NCT05422612 for Master Protocol information). Participants are randomized among the multiple cohorts in the study and the resulting randomization enables sharing/pooling of control subjects, where all interventions may be compared to a common control (placebo). This record only includes information relevant to the vilazodone cohort.
Once a participant meets all eligibility criteria for the Master Protocol, eligibility for each currently enrolling intervention cohort is assessed. Eligible participants will be randomized with equal probability into a cohort. Participants randomized to the vilazodone cohort are then randomly assigned to receive either vilazodone or placebo (in a ratio of 5:3; intervention:placebo), for the duration of the 12-week treatment period.
Parties interested in having their intervention considered for testing within the M-PACT should complete a request for information form using this webpage https://citeline.qualtrics.com/jfe/form/SV\_8eTQKw6TNug4z42.
