Major Depressive Disorder

Brief summary

This proposed study sets out to examine the antidepressant effects of tocilizumab among patients with treatment-refractory major depression.

Detailed description

As the understanding of the complex relationship between pro-inflammatory cytokines (specifically interleukin-6 \[IL-6\]) and depression symptoms becomes clearer, clinical trials to evaluate effective and novel treatments are needed. As there have been no published tocilizumab trials among patients with major depression, this pilot study will adopt a single-arm, open-label design. Due to the notion that inflammatory cytokines may play a role in a sub-type of depression, this study will recruit patients with treatment refractory major depressive disorder, for whom established depression treatments have not been effective. In conducting this trial, the investigators seek to examine the potential role of tocilizumab as an augmentation agent, with the hypothesis that it could reduce depression symptomatology in patients with major depression who have not experienced symptom reduction through more traditional antidepressant therapies.
