Brief Summary:
Studies show the presence of immuno-inflammatory disturbances in individuals with Bipolar Disorders (BD). Increased levels of circulating proteins known as cytokines that promote inflammation have been consistently reported in individuals with bipolar disorders. A particular cytokine referred to as Tumor Necrosis Factor (TNF)-alpha is among those cytokines that have been consistently identified across depressive, manic, and euthymic periods. Disturbances in inflammation however, are not seen in all individual with bipolar disorder. Those individuals with signs of inflammation also often present with higher prevalence of medical disorders that are also associated with inflammation. Those individuals with significant signs of inflammation may respond to anti-inflammatory treatments. In this study, individuals with bipolar depression who exhibit signs of high inflammation will be enrolled and treated with either an anti-inflammatory biologic known as infliximab or placebo (saline).

Drug Information available for: Infliximab

Arm Intervention/treatment
Experimental: Infliximab
Intravenous infliximab (5mg/kg) at baseline, week 2 and 6 under clinical observation
Drug: Infliximab
Intravenous infliximab (5mg/kg) at baseline, week 2 and 6 under clinical observation. Infliximab will be prescribed adjunctively to a conventional mood stabilizer or atypical antipsychotic agent.
Other Name: Remicade

Placebo Comparator: Saline (Placebo)
Intravenous placebo (saline solution) at baseline, week 2 and 6 under clinical observation. Placebo will be matched to infliximab in color and consistency.
Other: Saline
Intravenous placebo (saline solution) at baseline, week 2 and 6 under clinical observation. Placebo will be matched to infliximab in color and consistency and will be administered adjunctively to conventional mood stabilizer or atypical antipsychotic agent.




Primary Outcome Measures :
  1. Change from baseline in the Montgomery-Asberg Depression Rating Scale score [ Time Frame: Up to 12 weeks ]

Secondary Outcome Measures :
  1. Change in cytokine levels in the blood [ Time Frame: Up to 12 weeks ]
  2. Change in cognitive function (including executive function, attention, memory) [ Time Frame: Up to 12 weeks ]
  3. Change in brain volume and neuroprogression evaluated via neuroimaging (MRI and MRS) [ Time Frame: Up to 12 weeks ]
  4. Change in quality of life as measured by 36-Item Short Form Health Survey [ Time Frame: Up to 12 weeks ]
  5. Change in functional ability as measured by Sheehan Disability Scale and Endicott Workplace productivity Scale [ Time Frame: Up to 12 weeks ]
  6. Suicide risk will be assessed as a safety measure using the Columbia Suicide Severity Rating Scale [ Time Frame: Up to 12 weeks ]
