TREK: Ketamine-assisted Psychotherapy (KAP) for Patients With Existential Distress Associated With Non-operable GI Cancers
Study Details
Study Description
Brief Summary
The goal of this open-label clinical trial is to assess the feasibility of Ketamine-assisted psychotherapy (KAP) studies for adults with non-operable GI cancers suffering with existential distress. The main questions it aims to answer are:
-
Is it feasible to conduct a KAP study with this population?
-
What is the safety and tolerability of KAP in this population?
-
How prevalent is existential distress in this population?
Participants will undergo KAP administered as standard of care at the HMHI Park City Ketamine-Assisted Psychotherapy Clinic and will complete health assessments over the course of the study, as well as during the therapy.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Arm 1 Three 2.5-3 hour Ketamine Assisted Psychotherapy sessions, each 2-7 days apart |
Drug: Ketamine
Ketamine, 0.5-1.2mg/kg, administered intramuscularly
Doses can range 0.5-1.2 mg/kg. Starting dose for all participants will be 0.5mg/kg.
Dose can be titrated up to maximum of 1.2 mg/kg or titrated down to 0.5 mg/kg based on response and clinical judgement.
Dose will be administered by injecting into large muscle mass (eg, deltoid, gluteal muscle, thigh)

Outcome Measures
Primary Outcome Measures
- The rate of study completion by enrolled participants. Study completion is defined as participating in at least 2 of the 3 Ketamine-Assisted Psychotherapy (KAP) sessions. [One year]
To assess the feasibility of completion of the study intervention by 12 participants.
Secondary Outcome Measures
- The frequency of adverse events (AEs) and serious adverse events (SAEs) characterized by type, severity (as defined by the NIH CTCAE, version 5.0), seriousness, duration, and relationship to study treatment. [One year]
To assess the safety and tolerability of ketamine-assisted therapy in the study population.
- The proportion of screened patients that meet criteria on the Existential Distress Scale (EDS: Single domain ≥ 3 or total score ≥ 6). [One year]
To determine the prevalence of existential distress in patients with non-operable GI cancers.

-
Agree to refrain from using any psychoactive drugs, including alcoholic beverages, ondansetron, cannabis, and non-routine PRN medications within 24 hours of each ketamine administration. Exceptions include daily use of caffeine, nicotine, and opioid pain medication

Exceptions will be evaluated by the research team and will include acetaminophen, non-steroidal anti-inflammatory drugs, and common doses of vitamins and minerals.
