Ketamine Infusion for Adolescent Depression and Anxiety

Phase 4

Completed

Brief Summary: The purpose of this study is to determine the tolerability and short-term efficacy of a single ketamine infusion for the treatment of adolescents with 1) medication-refractory major depressive disorder (MDD) and/or 2) medication-refractory anxiety disorders (social anxiety disorder, panic disorder, generalized anxiety disorder and/or separation anxiety disorder).

Detailed Description: We will conduct a crossover trial in which as many as 36 adolescents (18 with MDD and 18 with anxiety disorders) will be given a single infusion of ketamine (study drug) or midazolam (active control). MDD symptoms and anxiety symptoms will be monitored over a two-week period. If applicable, comorbid school refusal symptoms will also be monitored over a two-week period for both cohorts. A 2-week washout period will be required between infusion doses. Our primary outcomes will be 1) improvement in MDD symptoms (measured by Montgomery-Asberg Depression Rating Scale, revised (MADRS) score) 1 day after infusion, for the cohort of subjects enrolled in the MDD arm of this trial and 2) improvement in the anxiety symptoms (measured by the Multimodal Anxiety Scale for Children (MASC) acute physical symptoms subscale) for the cohort of subjects enrolled in the anxiety disorders arm of the trial.

Primary Outcome Measures

Name	Time	Method
Montgomery-Asberg Depression Rating Scale Score 1 Day After Infusion	1 day after the infusion	Depressive symptoms (measured by Montgomery-Asberg Depression Rating Scale, revised (MADRS) score) on 1 day after infusion, for the cohort of subjects enrolled in the MDD arm of this trial. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60. Usual cutoff points are: 0 to 6 - normal /symptom absent. 7 to 19 - mild depression. 20 to 34 - moderate depression. \>34 - severe depression.
