NCT07187011
The purpose of this study is to test the drug PT150, which blocks glucocorticoid receptor (GR) signaling, for treatment of PTSD in Veterans, and establish a safety and efficacy profile that will inform the design of future studies.
NCT05453162
Proposed research will examine time-of-day effects on trauma-related fear extinction using Prolonged Exposure Therapy (PE) telemedicine for Posttraumatic Stress Disorder (PTSD) in the National Center for PTSD (NCPTSD). The primary mechanistic outcome measure will be change in psychophysiological reactivity to script-driven imagery (SDI-PR) measured, in person, at pre-treatment, after 5 PE sessions (mid-treatment), and after all 10 PE sessions (post-treatment). A secondary mechanistic outcome will be session-to-session reduction in peak subjective units of distress (SUDS) ratings to imaginal exposures. The primary clinical outcome will be change in Clinican Administered PTSD Scale (CAPS-5) severity score; a secondary clinical outcome will be session-to-session reduction in self-reported PTSD symptoms using the PTSD checklist (PCL-5). Participants meeting inclusion criteria (described below) will be randomized to either PE sessions that begin from 07:00 to a time no later than 2 hours past a participant's customary rise time, or to the last treatment session of the day beginning at 16:00 or later (26 per arm). Participants will complete daily at-home imaginal-exposure homework within the same time frame as their PE sessions are scheduled, i.e., within 2 hours of awakening for morning (AM) group and between 16:00 and 2 hours before bedtime for late afternoon (PM) group.
