Study Summary

This trial is comprised of a 4-week randomized, double-blind, placebo-controlled treatment period followed by an optional 8-week open-label extension (OLE) period. This trial will evaluate the efficacy and safety of oral PRAX-114 flexibly dosed at 40 to 60 mg for 4 weeks compared to placebo in adults with PTSD. The OLE period consisting of treatment with 40 mg PRAX-114 for 8 weeks will provide additional efficacy and safety data.

Primary Outcome

The CAPS-5 is a clinician-rated PTSD rating scale consisting of 30 items; the total score is calculated as the sum of 20 items assessing the 20 DSM-5 PTSD symptoms. These symptom items are scored on a 5-point scale from 0 (absent) to 4 (extreme/incapacitating). The total score of the 20 items ranges from 0 to 80 with higher scores indicating more severe PTSD symptoms. Therefore, a decrease in the total score indicates symptom improvement.
