NCT03889756

Brief Summary

The purpose of this study is to evaluate the intermediate-term efficacy and tolerability of a multiple-dosing ketamine infusion paradigm for the treatment of medication-refractory major depressive disorder (MDD). We are using a two-phase design. The first phase is a 3-week double blind parallel design clinical trial comparing 6 infusions of ketamine compared to 6 infusions of midazolam in 24 adolescents with treatment resistant depression. The primary outcome of this phase will be Children's Depression Rating Scale (CDRS) score at Day 18. The second phase is a 6-month open phase in which patients who received midazolam and remain depressed with be offered open ketamine treatment (6 infusions over 3 weeks). All participants will be followed weekly for 6 months and tracked for time to relapse.

Outcome Measures

Primary Outcomes (2)

  • Efficacy of a Multiple-dosing Ketamine Infusion Paradigm (2 Infusions Per Week for 3 Weeks) Compared to Midazolam in Adolescents With Treatment Resistant Depression Using the Children's Depression Rating Scale (CDRS)

    Establish if repeated ketamine will be efficacious medically and psychiatrically, as measured by a significant reduction in CDRS score in those treated with ketamine at the end of the dosing paradigm. The Children's Depression Rating Scale (CDRS) is a clinician-rated instrument with 17 items scored on a 1 to 5 or 1 to 7 scale. A rating of 1 indicates normal, thus the minimum score is 17. The maximum score is 113. Scores of 20-30 suggest borderline depression. Scores of 40-60 indicate moderate depression.

    Day 18

  • Tolerability of a Multiple-dosing Ketamine Infusion Paradigm (2 Infusions Per Week for 3 Weeks) Compared to Midazolam in Adolescents With Treatment Resistant Depression

    Establish if repeated ketamine will be tolerated as measured by drop-out counts.

    Day 18

Study Arms (2)

Ketamine

EXPERIMENTAL

Ketamine is an FDA-approved anesthetic agent that is commonly used to induce surgical anesthesia due to its low incidence of significant respiratory depression and hypotension. It as a N-methyl-D-aspartate (NMDA) receptor antagonist and glutamatergic modulator, and has been demonstrated in multiple controlled clinical trials to have rapidly acting antidepressant and anti-suicidal effects in adults.

Drug: Ketamine infusion

Midazolam

PLACEBO COMPARATOR

Midazolam, the active control in this study, is a medication that is approved by the Food and Drug Administration as a sedative for both children and adults.It is a benzodiazepine with a short half-life that was chosen so as to blind the psychotomimetic effects of Ketamine.

Drug: Midazolam infusion

Interventions

The dose of ketamine established in prior research (0.5 mg/kg over 40 minutes) will be used in this study to minimize risks. The maximum total single dose allowed in this study will be 40mg, corresponding to a weight of 80kg.

Ketamine

The weight-based midazolam dosing established in prior ketamine trials in adults (0.045mg/kg) will be used to minimize risks, as this is considered a very low dose compared to the sedation literature. The maximum total dose allowed in this study will be 3.6mg per infusion, corresponding to a weight of 80kg.

Midazolam

Eligibility Criteria
