Trial Outcomes & Findings for Ketamine in the Treatment of Depression (NCT NCT01558063)

NCT ID: NCT01558063

Last Updated: 2019-12-10

Results Overview

The quantitative depressive symptom ratings were collected at Baseline, Day 1 (post ketamine), Day 3 using HDRS-24 (a 24-item questionnaire used to provide an indication of depression, and as a guide to evaluate recovery). The total score can range from 0 to a maximum score of 15 with a higher score indicating a worse outcome. A "responder" was defined as an individual exhibiting a reduction in the HDRS score from baseline to 24 hours (day 1) post-treatment, and all other individuals were classified as non-responders.

SECONDARY outcome

Timeframe: Baseline and 120 minutes after infusion

Population: The data was not collected at 120 minutes and therefore was not analyzed for this outcome measure.

The dose-response curve as it refers to ketamine inducing a dose-dependent increase in glutamate levels with 1H Magnetic Resonance Spectroscopy (MRS) will be analyzed.
