Clinical Trial Summary

The primary objective of this study is to determine the effectiveness of serial infusions of intravenous (IV) ketamine in adults with treatment resistant depression (TRD).

Description:

Thus, in the current study we want to naturalistically explore the antidepressant effects of serial slow IV infusions (40 minutes) of ketamine at a dose of 0.5 mg/kg, over a treatment period of 8 weeks in an academic psychiatric hospital. This is a minimal sedation treatment. The primary outcome measure of this study will be remission estimated based on the severity of depressive scores. After the 8 weeks of treatment, there will be a four week observational period. During the observational period, participants will receive treatment as usual and will be contacted over the phone for follow-up questions regarding their overall health status, mood and clinical state. They will also complete a neurocognitive task at the end of the 4 week observational period

Suffering from uncontrolled hypertension or diastolic BP over 100. Cardiac clearance prior to enrolling in the study/medical records from physician will be required per patient's primary care physician (PCP).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety Will be Measured Through Number of Adverse Events		Baseline through week 12
Secondary	Efficacy of Treatment Will be Measured on of Clinical Global Impressions (CGI)		Baseline, week 8, week 12
Secondary	Severity of Depressive Symptoms as Assessed by the PHQ-9	The Patient Health Questionnaire (PHQ)-9 is the 9-item depression module from the full Patient Health Questionnaire (PHQ) PHQ-9 total score ranges from 0 to 27 (each of the 9 items can be scored from 0 (not at all) to 3 (nearly every day)), and a higher score indicates greater depression.	Baseline, week 8, week 12
