Brief Summary:
Ketamine infusions resulted in an acute reduction in global depression scores and in severity of suicidal ideation. The investigators therefore plan to investigate the feasibility and efficacy of repeated intravenous administration of ketamine in severely depressed, treatment resistant patients. The results of the study could lead to development of new strategies for treating depression.

Arm Intervention/treatment
Experimental: Ketamine
Subject will receive 6 infusions of ketamine over three weeks.

Primary Outcome Measures :
  1. Hamilton Depression Rating Scale - Suicidal Ideation (HDRS-SI) [ Time Frame: up to 4 months ]
    The HDRS-SI score consists of a single item on the Hamilton Depression Rating Scale (HDRS). Scores range from 0 to 4, with 0 representing no suicidal ideation, and 4 representing a suicide attempt.

Secondary Outcome Measures :
  1. HDRS-28 Total [ Time Frame: up to 5 months ]
    Hamilton Depression Rating Scale Total scores after completing 6 infusions. Scores may range from 0-81 with higher scores indicating greater depression severity. HDRS-28 score ≤ 7 was considered remission.
