Official title

Neutralizing Interleukin (IL)-6 Signaling to Reverse Immune Related Anhedonia in Patients With Major Depressive Disorder

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The proposed study aims to establish the feasibility and safety of subcutaneous tocilizumab, a monoclonal antibody (mAb) against interleukin (IL)-6 receptor, in adults with Major Depressive Disorder (MDD) and evidence of peripheral immune activation. IL-6 is a pro-inflammatory cytokine implicated in the pathophysiology of depression. The investigators hypothesize that neutralizing peripheral immune signaling via IL-6 receptor blockade with tocilizumab will improve neural and behavioral measures of reward processing. This is an open-label, proof-of concept, trial in which up to N=20 adults with MDD meeting a specific immune enrichment criterion will receive open-label tocilizumab over 8 weeks. A healthy control (HC) group (N=20) will undergo baseline neuroimaging and blood-based biomarker assessment without receiving the study drug to aid interpretation of findings. Blood-based immune markers and brain MRI scans (including task-based reward activation and resting-state functional connectivity) will be assessed at baseline for all participants and again post treatment for the MDD group.
