Trial Outcomes & Findings for Ketamine for Severe Adolescent Depression: Intermediate-term Safety and Efficacy (NCT NCT03889756)

NCT ID: NCT03889756

Last Updated: 2023-04-24

Results Overview

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.

Ketamine
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. Ketamine infusion: 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.
Midazolam
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. Midazolam infusion: 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.
