Brief Summary

Major depression is increasingly recognized to be a chronic and highly recurrent condition, which results in significantly increased health problems. One possible mechanism that may contribute to treatment resistance is increased production and release of chemicals called proinflammatory cytokines in patients with major depression. These chemicals mediate the body's response to infectious agents like bacteria and have been shown to be increased by psychological stress. They produce the symptoms that we associate with being sick, including fever, malaise and changes in sleep and appetite. Several lines of evidence indicate that proinflammatory cytokines may contribute to the development of major depression and may thus represent a novel target for the pharmacological treatment of the disorder. The TNF-alpha antagonist, Infliximab (Remicade®), is an infusion style drug approved by the FDA for the treatment of inflammatory conditions like Crohns disease and rheumatoid arthritis. The researchers are conducting a study to see if the infliximab (Remicade®) is more effective than placebo in acutely reducing symptoms of depression in patients who have elevated proinflammatory markers and have not responded to, or been unable to tolerate, at least two previous treatments in the current depressive episode. Proinflammatory markers are measured by a simple blood test for C-Reactive Protein (CRP) levels in the body.

Outcome Measures

Primary Outcomes (1)

  • Hamilton Depression Rating Scale 17 (HDRS-17) Scores

    The HDRS is a 17-item survey asking respondents to rate the degree of depressive symptoms they are feeling on a scale of 0 to 2-4, where 0 means the symptom is absent and 2-4 means the symptom is very strong. Total scores can range from 0 to 52 where higher scores represent greater symptom severity. Scores of 0-7 are considered normal, scores of 8-16 indicates mild depression, scores of 17-23 indicate moderate depression, and scores of 24 and greater indicate severe depression.

    Baseline, Weeks 1, 2, 4, 6, 8, 10 and 12

Secondary Outcomes (9)

  • Number of Participants With a 50% Reduction in Hamilton Depression Rating Scale (HDRS) Scores

    Week 12

  • Number of Remitted Patients During Treatment

    Week 12

  • Inventory of Depressive Symptomatology-Self-Report (IDS-SR) Scores

    Baseline, Weeks 1, 2, 4, 6, 8, 10 and 12

  • Plasma Concentrations of Interleukin-6 (IL-6)

    Baseline, Week 12

  • Plasma Concentrations of CRP

Eligibility Criteria

Age25 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Males or females ages 25-60. Must be able to read and understand English.
  • Currently meets the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-IV) criteria for a major depressive episode. (History of either unipolar major depression (depressive episodes only) or bipolar I disorder (history of manias and depressions) or bipolar II disorder (hypomanias and depressions), current episode depressed acceptable).
  • Must meet criteria for "treatment resistant" depression defined by failure to respond to, or intolerance of, at least 2 treatment trials (antidepressants or ECT) during the current episode.
  • All subjects will be fully ambulatory and in good medical health.
  • Are required to either be antidepressant free for 2 weeks prior to study entry (4 weeks for fluoxetine secondary to long half-life) or be on a fixed psychotropic medication regimen for at least 4 weeks. Subjects and their primary care providers must agree to continue their status (i.e. without antidepressant or on a fixed regimen) until the 12-week assessment is complete.
  • Pre-menopausal female subjects must not be pregnant and must be willing to use adequate contraception during the study period.

You may not qualify if:

  • Current or history of psychotic symptoms.
  • Active suicidal ideation (defined as a score of ≥3 on Hamilton Depression Rating Scale (HDRS) suicide item).
  • Prior use of a TNF-alpha antagonist (i.e. etanercept, infliximab, adalimumab) and use of any other immunosuppressant agent (i.e. systemic corticosteroids or anti-proliferative agents such as methotrexate) within one year of study entry.
  • Current use of aspirin, non-steroidal anti-inflammatory agents (NSAIDs) or cyclooxygenase-2 (COX-2) inhibitors during the study. Acetaminophen will be allowed.
  • History of any of the following conditions: Congestive heart failure, abnormal electrocardiogram, malignancy, schizophrenia, neurological disease, auto-immune condition (e.g. rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis, lupus), chronic infection (e.g. human immunodeficiency virus, hepatitis B or C), and hematologic, renal or hepatic abnormality.
  • Subjects will be excluded for a positive anti-double stranded DNA antibody test.
