KAP for Depression in Abstinent Opioid Users

Overview

The purpose of the study is to examine whether an investigational medication called ketamine along with psychotherapy is an effective treatment for depression in participants with a history of opioid addiction who have not abused opioids in at least 3 months. Participants will receive ketamine through intramuscular injection along with psychotherapy weekly for 8 weeks. Participation for eligible subjects who decide to enroll (including post-medication follow-up visits) will last about 16 weeks or 4 months.

Clinical Trial Outcome Measures

Primary Measures

  • Montgomery Asberg Depression Rating Scale
    • Time Frame: Change from baseline measured at week 9
    • Clinician-administered rating of depressive symptoms; minimum score of 0, maximum score of 60; a decrease in score means a better outcome (less depressed)

Secondary Measures

  • Beck Depression Inventory
    • Time Frame: Change from baseline measured at week 1-9, 10, 12, and 16
    • Self-rated depression inventory; minimum score of 0 maximum score of 63 with lower scores being a better outcome (less depressed)
  • Visual Analog Scale (VAS)
    • Time Frame: Measured at week 1-9, 10, 12, and 16
    • Measure of subjective level of opioid craving; maximum score of 100 and minumum score of 0 with higher scores meaning worse outcome (more cravings)

    • Time Frame: Measured at week 1-9, 10, 12, and 16
    • Measure of PTSD symptoms; maximum score 80 and minimum score of 0 with higher scores indicating worse outcome (more PTSD symptoms)
  • Timeline Follow-back (TLFB)
    • Time Frame: Measured at week 1-9, 10, 12, and 16
    • Measure of Substance Use; maximum number of substance use days per week is 7 and minimum is 0 with higher number indicating worse outcomes (more substance use)
  • Montgomery Asberg Depression Rating Scale
    • Time Frame: Change from baseline measured at week 2-8, 10, 12, and 16
    • Clinician-administered rating of depressive symptoms; minimum score of 0, maximum score of 60; a decrease in score means a better outcome (less depressed)

Subjects taking other psychotropic medications (e.g. anti-depressants, anxiolytics, methadone, buprenorphine, naltrexone) must be maintained on a stable dose for at least four weeks before study initiation. Exclusion Criteria Subjects will be excluded from the study if any of the following criteria apply: 1. They are considered an immediate suicide risk by clinician assessment, self-reports a suicide attempt within the past year, or felt to be likely to require hospitalization during the study. 2. Subjects who meet DSM-5 criteria for current bipolar disorder based on clinical interview. 3. Subjects who meet DSM-5 criteria for current or history of psychotic spectrum disorders based on clinical interview. 4. Subjects meeting DSM-5 criteria for current substance use disorder (i.e., not in early or sustained remission) other than tobacco use disorder. 5.
