Purpose
This study will examine the effectiveness of omega-3 fatty acids, compounds found in plants and fish, in treating bipolar disorder.
Some studies have indicated that omega-3 fatty acids may be effective in treating mood disorders.
For example, one investigator has shown a correlation between the prevalence of major depression and the amount of fish consumed per capita worldwide. Others have found decreased amounts of EPA (one of the active ingredients in omega-3 fatty acids) in the red blood cells of patients with major depression. And a recent small study of patients with bipolar illness indicated that omega-3 fatty acids prevented relapses, especially of depression, in patients.
Patients with bipolar disorder who are not benefiting satisfactorily on their current medications are eligible to participate in this study. Candidates will be screened with a psychiatric evaluation, routine blood tests, a urine test and other tests needed to monitor medications. Participants will be randomly assigned to one of two groups: one group will receive 6 grams of omega-3 fatty acid every day for 16 weeks; the second will receive a placebo (inactive capsule). In addition, patients in both groups will continue to take their previous medications. Every 2 weeks, all patients will have their vital signs checked and be evaluated for side effects and mood changes. At the end of the 16-week study period, all patients will be given the opportunity to continue in the study for another 8 months and receive active drug (omega-3 fatty acid). Patients who continue will be evaluated once a month and will have blood drawn on the last visit for routine tests.

| Official Title: | Omega-3 Fatty Acids in the Treatment of Major Depression and Bipolar Disorder: A Double-Blind, Placebo-Controlled Trial |

| Study Start Date: | October 1999 |
| Estimated Study Completion Date: | August 2002 |
The aim of this study is to examine the efficacy of omega-3 fatty acids in the form of eicosapentaenoic ethyl esters (EPA) - in the treatment of bipolar disorder. Omega-3 fatty acids are long-chain, polyunsaturated fatty acids found in plant and marine sources. There are preliminary data to suggest that omega-3 fatty acids may be efficacious in the treatment of mood disorders. Patients in our bipolar outpatient clinic will be at one of the five NIMH - Stanley Foundation Bipolar Network (the "Network") sites participating in this project. Subjects will be randomly assigned in a double-blind manner to 6 grams per day of omega-3 fatty acids or placebo (paraffin capsules) as an "add-on" to ongoing treatment with mood stabilizing medication(s) which have proven unsatisfactorily effective within therapeutic range(s) or at maximum tolerated dose(s). The double-blind trial will continue for 4 months duration. Patients will then be offered the option of entering an eight month, open-label trial of omega-3 fatty acid. The hypothesis of this study is that omega-3 polyunsaturated fatty acids in the form of eicosapentaenoic acid (EPA) acting on some of the same signal transduction mechanisms as the mood stabilizers will be beneficial in breakthrough depression, mania and cycling of bipolar disorder.
