The Montgomery Asberg Depression Scale (MADRS) is a 10-item observer rating scale assessing symptoms of depression. The score ranges from 0 (no depression) to 60 (very depressed). For this study a score of less than or equal to 9 was considered clinical remission of depression.
Ketamine for Depression and Suicide Risk
Brief Summary
The purpose of this research study was to find out if the medication known as ketamine could help the symptoms of depression. This drug is approved by the U.S. Food and Drug Administration (FDA) as an anesthetic agent; however, it is not approved for use in depression treatment. The FDA allowed the use of this drug in this research study.

Location
This was a single-arm, open-label trial conducted in two phases. During the acute-phase, i.v. ketamine was administered thrice-weekly for up to 2 weeks.Those who achieved depressive symptom remission (Montgomery Åsberg Depression Rating Scale (MÅDRS)) total score less than or equal to 9 measured 24h after any acute-phase infusion) received continuation-phase treatment that consisted of once-weekly i.v. ketamine infusions for 4 additional weeks. Remission could occur after any of the 6 acute-phase infusions, at which point the next infusion was the first (of four) continuation-phase infusions. Individuals who remitted during acute-phase and completed continuation-phase treatment had 4 additional weekly post-continuation follow-up visits.Those who responded to i.v. ketamine (less than or equal to 50% reduction from baseline in MÅDRS total score) but did not remit during acute-phase were not eligible for continuation-phase treatment. Suicidal ideation was assessed clinically throughout the trial, supplemented by scores on the MÅDRS suicide item.

The Montgomery Asberg Depression Scale (MADRS) is a 10-item observer rating scale assessing symptoms of depression. The score ranges from 0 (no depression) to 60 (very depressed). For this study a score of less than or equal to 9 was considered clinical remission of depression.
-
The MADRS test includes 10 items and uses a 0 to 6 severity scale for each item, with higher scores indicating increasing depressive symptoms. MADRS Factor 1 (Sadness) consisted of MADRS items 1 (Apparent Sadness) and 2 (Reported Sadness). The MADRS Factor 1 Score is derived by adding all the scores from the 2 items, meaning the lowest possible score is 0 and the highest possible is 12.
