Brief Summary:
The purpose of this study is to evaluate minocycline as a potential treatment for bipolar depression when added to a mood-stabilizing medication. Minocycline is an antibiotic that is approved for the treatment of infections and acne. Participation in this research study is expected to last 8 weeks, and includes five outpatient visits.

Condition or disease Intervention/treatment Phase
Bipolar Depression Drug: Minocycline Phase 4

Detailed Description:
Bipolar depression remains the great unmet need in the treatment of bipolar disorder. Only two treatments have been FDA-approved for the management of acute bipolar depression (the combination of olanzapine and fluoxetine and quetiapine). Early pilot data suggests the drug minocycline has potent antidepressant effects. Minocycline is approved by the Food and Drug Administration (FDA) (for acne and bacterial infections), is inexpensive and readily available in generic formulation, and is generally well-tolerated. This study will examine whether administering the drug minocycline to individuals with bipolar depression over 8 weeks will improve their depressive symptoms. This study will also offer an option to participate in proton magnetic resonance spectroscopy (1H-MRS) to measure N-Acetylaspartate (NAA) levels in the brain, which are thought to be decreased in bipolar disorder.

Arm Intervention/treatment
Experimental: Minocycline
All subjects will be given minocycline over 8 weeks
Drug: Minocycline
Minocycline 100 to 300mg per day for 8 weeks
Other Name: Minocin

Primary Outcome Measures :
  1. Change in Scores on the Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: baseline and week 8 ]
    Measured at baseline and week 8. The 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. Change in N-acetylaspartate (NAA), as Measured by 1H-MRS Scan [ Time Frame: baseline and week 8 ]
    Measured at baseline and week 8

  2. Changes in Young Mania Rating Scale (YMRS) [ Time Frame: baseline and week 8 ]
    Measured at baseline and week 8. The YMRS is an 11-item questionnaire to measure the severity of manic symptoms. 7 items are scored 0-4 and the other 4 items are scored 0-8, with overall score range from 0 (normal) to 60 (severe mania).
