Ketamine Infusion for Treatment-resistant Major Depressive Disorder
Ketamine infusion has been shown to have rapid antidepressant properties, however the possible use of ketamine in treatment-resistant depression as augmentation has not been investigated. The overall aim of this study is to assess the feasibility, safety and tolerability, efficacy and duration of the effect of intravenous N-methyl-D-aspartate antagonist ketamine as augmentation of antidepressants for chronic suicidal ideation in subjects with severe treatment-resistant depression (TRD).
This is an open-label study (pilot).

Experimental: Ketamine IV
Patients will receive open label augmentation with IV Ketamine at 0.5mg/kg, twice a week for 3 weeks
Ketamine IV 0.5mg/kg infusion twice a week for 3 weeks as augmentation of ongoing antidepressant regimen
Patients will undergo two weeks of prospective observation, they will then receive ketamine IV 0.5mg/kg over 45 minutes as augmentation of their ongoing antidepressant regimen; after three infusions this dose will be increased increase to 0.75 mg/kg in non-responders.
