Primary Outcome Measures:
  • Hamilton Rating Scale for Depression - 6 items [ Time Frame: Past 24 hours ] [ Designated as safety issue: No ]
    This instrument is completed with a structured interview guide by the clinician based on his/her assessment of the patient's symptoms. This structured interview has been validated for use with time frames shorter than one week. The time frame for this scale is the past 24 hours.

Estimated Enrollment: 100
Study Start Date: December 2014
Estimated Study Completion Date: March 2016
Estimated Primary Completion Date: January 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Ketamine 0.1mg
Patients in this arm will receive 0.1 mg/kg of Ketamine - one single infusion
Drug: Ketamine
Dose of Ketamine will be 0.1 mg/kg - one single infusion
Active Comparator: Ketamine 0.2mg
Patients in this arm will receive 0.2 mg/kg of Ketamine - one single infusion
Drug: Ketamine
Dose of Ketamine will be 0.2 mg/kg - one single infusion
Active Comparator: Ketamine 0.5mg
Patients in this arm will receive 0.5 mg/kg of Ketamine - one single infusion
Drug: Ketamine
Dose of Ketamine will be 0.5 mg/kg - one single infusion
Active Comparator: Ketamine 1.0mg
Patients in this arm will receive 1.0 mg/kg of Ketamine - one single infusion
Drug: Ketamine
Dose of Ketamine will be 1.0 mg/kg - one single infusion
Placebo Comparator: Midazolam (Active Placebo)
Patients in this arm will receive 0.045 mg/kg of midazolam - one single infusion
Drug: Placebo Midazolam
Dose of Midazolam (active placebo) will be 0.045 mg/kg - one single infusion

Detailed Description:

The primary objective is to investigate whether all doses (0.1 mg/kg, 0.2 mg/kg, 0.5 mg/kg, and 1.0 mg/kg) of ketamine are superior to active placebo (midazolam 0.045 mg/kg) therapy in the acute treatment of patients with treatment resistant depression within 72 hours (Day 3), when added to ongoing and stable antidepressant therapy.
