Clinical Trial 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.


Clinical Trial Description

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). The specific aims of the study are: To evaluate the efficacy and tolerability of a multiple-dosing ketamine infusion paradigm (2 infusions per week for 3 weeks) compared to midazolam in adolescents with treatment resistant depression (TRD), . To test these aims we have designed a two-phase trial. 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 TRD. 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. In those who initially responded to ketamine, symptom triggered maintenance infusions will be offered during this 6-month time period. All participants will receive standard of care treatment in addition to experimental procedures, and will be tracked monthly with extensive neurocognitive assessments. ;
