Current treatments for PTSD do not work for a significant proportion of individuals with PTSD, or work only partially, leaving persistent and disabling residual symptoms. The research team has led the development of ketamine for the treatment of chronic PTSD. After the initial, proof-of-concept randomized controlled trial (RCT) of a single ketamine infusion in individuals with chronic PTSD showed promising results, the study team recently completed the first RCT of repeated intravenous ketamine infusions where individuals with chronic PTSD received a course of six ketamine infusions (vs. active placebo midazolam infusions) and demonstrated a rapid and robust improvement in PTSD symptoms. Median time to loss of response, however, occurred a few weeks following the course of infusions, making it imperative to investigate novel approaches aimed at preventing symptom relapse following ketamine treatment. The study team proposes a proof-of-concept, open-label pilot study to evaluate the efficacy of adding an evidence-based, brief and scalable trauma-focused psychotherapy, Written Exposure Therapy (WET), to a course of ketamine infusions in maintaining PTSD symptom improvement over time, in participants with chronic PTSD who respond to initial ketamine infusions. To accomplish this aim, the study team will enroll individuals who meet DSM-5 criteria for chronic PTSD. Patients who show an initial response to four ketamine infusions will be participate in WET (a total of five sessions), and will additionally receive the remaining two ketamine infusions (to complete a total course of six infusions). The primary outcome will be time to loss of response, assessed with the Clinician-Administered PTSD Scale for DSM-5. The study team will also evaluate whether extinction learning ability -assessed with a computerized extinction learning task- predicts maintenance of ketamine response over time, and will explore potential sociodemographic and clinical predictors of longer maintenance of ketamine response. If demonstrated to prolong time to loss of response to ketamine, this novel combined treatment may represent a promising intervention for individuals with chronic PTSD, deserving further study.
