A Screening and Baseline visit Clinician-Administered Inventory of Depressive Symptomatology Questionnaire (IDS-C30) score ≥ 25.
Screening visit high-sensitivity C-reactive protein (CRP) concentration ≤ 5 mg/L (based on evidence that cytokine antagonism has an independent antidepressant effect in depressed patients with elevated CRP above this cut-off).

Exclusion Criteria:

Any of the following medical conditions:

cardiovascular disease (other than controlled hypertension)
