Trial Outcomes & Findings for Ketamine Infusion for Adolescent Depression and Anxiety (NCT NCT02579928)

NCT ID: NCT02579928

Last Updated: 2020-07-14

Results Overview

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.

Participant Flow

Adolescents (aged 13 to 17 years old) were recruited via (1) physician referral or (2) via direct inquiries from families via ClinicalTrials.gov listing. Subjects were enrolled at the Yale Child Study Center (New Haven, CT) between May 2016 and September 2018.

Participants were to remain on stable dosing of their current medication regimen for the four weeks prior to the first infusion, and during the four-week trial itself. All participants underwent a physical examination, laboratory screening, and electrocardiography.

Measure
Ketamine First Then Midazolam
Participants received a Ketamine infusion under blinded conditions, followed by a Midazolam infusion 14 days later. The subject were monitored continuously during both infusions, and every hour for three hours after the infusion and then followed clinically for two weeks. Ketamine was infused at a dose of 0.5mg/kg over 40 minutes and midazolam was infused at a dose of 0.045mg/kg over 40 minutes on the Hospital Research Unit of YNHH.
Midazolam First Then Ketamine
Participants received a midazolam infusion under blinded conditions, followed by a ketamine infusion 14 days later. The subject were monitored continuously during both infusions, and every hour for three hours after the infusion and then followed clinically for two weeks. Midazolam was infused at a dose of 0.045mg/kg over 40 minutes and ketamine was infused at a dose of 0.5mg/kg over 40 minutes on the Hospital Research Unit of YNHH.

PRIMARY outcome

Timeframe: 1 day after the infusion

Population: A total of 17 patients were randomized to receive either Ketamine or Midazolam in the first infusion, one participant in withdrew from the trail after the first infusion because of improvement in her depressive symptoms and did not receive the second 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.
