January 26, 2024 updated by: Paulo Shiroma, Minneapolis Veterans Affairs Medical Center

Examining the Efficacy and Safety of Subanesthetic Ketamine on Depression and Post-traumatic Stress Among Veterans With Mild and Moderate Traumatic Brain Injury

The goal of this clinical trial is to examine the use of sedative ketamine to treat depression and post-traumatic stress disorder (PTSD) in Veterans with mild to moderate traumatic brain injury (TBI). The main questions it aims to answer are:

  • Efficacy of ketamine to reduce symptoms of depression and/or PTSD
  • Safety of ketamine to treat depression and/or PTSD in TBI Participants will be randomly assigned to receive either ketamine or midazolam (active placebo) twice a week for 3 weeks. During participation, subjects will be interviewed, have lab tests, and complete rating scales, and questionnaires.

  • Lifetime history of treatment resistance to at least one adequate trial of an antidepressant as determined by the Massachusetts General Hospital Antidepressant Treatment History Questionnaire (MGH-ATRQ).
  • FDA-approved antidepressant, trazodone, atypical neuroleptic, prazosin, or clonidine with stable treatment, as determined by the study clinician, for at least 4 weeks prior to randomization. Following randomization, changes to doses may be allowable at the investigator's discretion

Exclusion Criteria:

  • Ketamine treatment within the last 6 months

    • Lifetime history of psychosis-related disorder, current episode of mania/hypomania/mixed assessed by the Mini-International Neuropsychiatric Interview (MINI 7.0 for DSM-5).
    • History of penetrating head wounds or severe traumatic brain injury (Glasgow Coma Scale <9; loss of consciousness >24hr; post-traumatic amnesia>7 days).
    • Severe substance and/or alcohol use disorder (DSM-5-TR) within six months of initial assessment; presence of illicit drugs (except cannabis) by positive urine toxicology at screening.
    • Intellectual disability or pervasive developmental disorder; dementia of any type.

Women who are surgically sterile or have been post-menopausal for at least 1 year will not be excluded
    • At screening, resting blood pressure (sitting or supine) lower than 90/60 or higher than 150/90, or resting heart rate lower than 45/min or higher than 100/min.
    • Imminent risk of suicidal/homicidal ideation and/or behavior with intent and/or plan.
    • Concurrent participation in a cognitive rehabilitation program, however patient will have a TBI clinician involved in directed services.
    • Subjects on a prohibited medication: monoamine oxidase inhibitors, memantine, long acting benzodiazepines (i.e., Chlordiazepoxide, Diazepam, Flurazepam)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Severity of Depressive Symptoms
Time Frame: 3 weeks
Total score on the Montgomery- Åsberg Depression Rating Scale , a semi- structured 10-item scale. Range 0-60. Higher values represent worse outcomes. The total score is obtained by summing the severity score of each item.
3 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Severity of Post-traumatic Stress Disorder (PTSD) Symptoms
Time Frame: 3 weeks
Total score on the PTSD Checklist for DSM-5 (PCL-5), a 20-item self-report measure that assesses the 20 DSM-5 symptoms of PTSD. The total score is obtained by summing the score of each item.
3 weeks
