Overview
Brief Summary
The objectives of this study are to investigate the feasibility, tolerability, and preliminary efficacy of repeated ketamine-assisted psychotherapy sessions in adolescents with severe posttraumatic stress disorder. The study will enroll adolescents with a current diagnosis of posttraumatic stress disorder (PTSD) to complete three intravenous ketamine administrations accompanied by a psychotherapy session over the span of six weeks. All participants will complete an initial set of preparatory sessions, and each dosing session will be followed by three to six hours of integration sessions. Finally, participants will complete 7 nights of at-home sleep recordings. The investigators hypothesize that this protocol will be well-tolerated by adolescents and that patients will experience decreases in PTSD symptom severity at follow-up.
Detailed Description
Primary Objective: * Characterize safety and adverse events associated with repeated ketamine-assisted psychotherapy in adolescents with PTSD. Secondary Objectives: * Evaluate initial feasibility of recruitment and retention of adolescents with PTSD. * Explore potential impacts of ketamine-assisted psychotherapy on PTSD symptom severity at follow-up

Eligibility Criteria
Inclusion Criteria
- •Aged 15-17 years old, inclusive
- •At baseline, meet threshold for Diagnostic and Statistical Manual (DSM-5) criteria for current PTSD as determined by the CAPS-CA.
- •Medically and neurologically healthy on the basis of physical examination, medical history, and the clinical judgement of the evaluating study medical provider
- •Must agree to inform the investigators within 48 hours of any emergent medical conditions and procedures
- •If of childbearing potential, must have a negative pregnancy test at study entry and prior to each KAP dosing session, and must agree to use adequate birth control through 10 days after the last KAP dosing session.
- •Must agree not to participate in any other interventional clinical trials during the duration of the study
- •Must be willing to comply with all study procedures
- •A primary parent or guardian is willing to provide informed consent
- •Are fluent in or predominantly speaking and reading in English
Exclusion Criteria
- •Caregiver or adolescent is unwilling or unable to give adequate informed consent
- •Are likely, in the investigator's opinion and via observation during the Preparatory Period, to be re-exposed to their index trauma or other significant trauma, lack social support, or lack a stable living situation during study participation.
- •Any finding(s), based on the screening process, that the PI feels would make the study unsuitable for the participant.
- •Current diagnosis of or history of a psychotic disorder, bipolar disorder, or autism spectrum disorder diagnosed by the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS) interview and clinician judgement. No other co-morbid disorders are exclusionary.
- •Intellectual disability (IQ\<70) per medical history
- •History of moderate to severe substance use disorder, as determined by the KSADS and/or clinician judgement (excluding tobacco), or active substance use (including current alcohol use or positive urine toxicology)
- •Any prior exposure to sub-anesthetic doses of ketamine (including prior research or clinical psychiatric treatment with ketamine and/or recreational use)
- •Any participant presenting current serious suicide risk, as determined through the KSADS, responses to Columbia Suicide Severity Rating Scale (C-SSRS), and/or clinical judgment of the investigator, will be excluded; however, history of suicide attempts prior to enrollment is not an exclusion.
- •Would present a serious risk to others as established through clinical interview and contact with treating physician.
- •Current use benzodiazepines, opiates, or lamotrigine, which are hypothesized to interfere with ketamine's mechanism of action

Outcomes
Primary Outcomes
Summary of Adverse Events Attributable to Ketamine Administration
Time Frame: through the last study visit, up to 10 weeks
Degree of adverse effects (AEs) attributable to ketamine administration as categorized according to the abbreviated (six-item) Clinician-Administered Dissociative States Scale (CADSS-6), which assesses situation-dependent dissociative states, and the Systematic Assessment for Treatment Emergent Events (SAFTEE-GI), which uses a standardized general (SAFTEE-GI) inquiry of physical/health problems and possible treatment-emergent side effects. The SAFTEE-GI will be administered during the preparatory period, at every KAP dosing session, integration, and endpoint assessment visit, the CADSS-6 will be administered at every KAP dosing session and during each integration period. Reported here are a list of AEs attributed to KAP Administration with count of participants experiencing them.
Secondary Outcomes
- Number of Participants Adhering to the Study Protocol(up to 10 weeks)
- Number of Visits Completed Throughout the Study Duration(up to 10 weeks)
