Department of Defense PTSD Adaptive Platform Trial - Intervention C - Daridorexant

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 daridorexant 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 daridorexant cohort are then randomly assigned to receive either daridorexant or placebo (in a ratio of 5:3; intervention:placebo), for the duration of the 12-week treatment period.
