Brief Summary:

The purpose of this study is to test the antidepressant effect of ketamine when given repeatedly over a period of 1 week, as well as the use of Lithium as a relapse-prevention strategy for patients with treatment-resistant depression (TRD) who respond to an initial series of ketamine infusions. Ketamine is a Food and Drug Administration approved anesthetic (a drug used to produce loss of consciousness before and during surgery). Ketamine is not approved for the treatment of major depressive disorder and is considered experimental in this study. An additional purpose of this study is to research the effects of ketamine on brain function.

You may qualify to take part in this research study because you have been diagnosed with major depressive disorder (MDD) and have not responded to past treatments.

Depression Drug: Lithium Drug: Ketamine Drug: Placebo Phase 2

Detailed Description:
Major Depressive Disorder (MDD) is a disabling medical illness and current monoaminergic treatments are slow to act and possess only limited efficacy. In this context, the discovery that the glutamate NMDA receptor antagonist ketamine is rapidly antidepressant (onset of action within hours) -- even in patients suffering from treatment-resistant depression (TRD) -- has ignited tremendous enthusiasm among clinicians, scientists and patients alike. A critical obstacle to the translation of this discovery into a novel treatment, however, is the limited duration of action following a course of ketamine (e.g. 1-2 weeks). The current project will address this important gap in medical knowledge by testing a rational neuropharmacological strategy designed to optimize and sustain the rapid antidepressant effects of ketamine. Driven by the recent characterization of the molecular mechanisms underpinning the antidepressant and neuroplasticity effects of ketamine, we will test the combination of ketamine plus lithium in patients with TRD using a randomized, double blind, placebo-controlled design. The primary aims of the project are (1) to test the efficacy of lithium-plus-ketamine compared to placebo-plus-ketamine as an antidepressant combination strategy in TRD and (2) to gather data on the safety and tolerability of the lithium-plus-ketamine.

Primary Outcome Measures :
  1. MADRS-S Score [ Time Frame: 2 weeks after last ketamine infusion ]
    The Montgomery Asberg Depression Rating Scale (MADRS-S) has 10-items which are based on mood symptoms over the past 7 days. Each items is scored 0 (normal) to 6 (severe depression) with overall score ranges from 0 (normal) to 60 (severe depression).


Secondary Outcome Measures :
  1. QIDS-SR Score [ Time Frame: 2 weeks after last ketamine infusion ]
    Quick Inventory of Depressive Symptomatology, Self-Report (QIDS-SR) score - Each item is rated 0 (no depression) to 3 (severe depression), for a total score range of 0 (no depression) to 27 (severe depression).

  2. CGI-S Score [ Time Frame: 2 weeks after last ketamine infusion ]
    The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill.

  3. HAM-A Score [ Time Frame: 2 weeks after last ketamine infusion ]
    Each item is scored on a scale of 0 (not present) to 4 (severe), with a total score range of 0-56, where <17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe.

  4. BSS Score [ Time Frame: 2 weeks after last ketamine infusion ]
    BECK Scale for Suicidal Ideation (BSS) - 0-13 Minimal; 14-19 Mild; 20-28 Moderate; 29-63 Severe

  5. CSSRS Score [ Time Frame: 2 weeks after last ketamine infusion ]
    Columbia Suicide Severity Rating Scale (CSSRS) - Full range from 0 (low intensity suicidal ideation to 9 (high intensity suicidal ideation).

  6. Patient Rated Inventory of Side Effects (PRISE) [ Time Frame: 2 weeks after last ketamine infusion ]
    Number of Participants with PRISE
