|Condition or disease||Intervention/treatment||Phase|
|Bipolar Disorder||Drug: Ramelteon Drug: Placebo||Phase 4|
Patients with euthymic bipolar disorder, although free of significant mood symptoms, often have continued sleep disturbances. Improving patients' sleep by also normalizing the circadian rhythm will lead to fewer mood exacerbations. Ramelteon offers a new and more pharmacologically exact mechanism to re-synchronize the SCN. The administration of ramelteon for bipolar patients will improve sleep and will cause fewer mood exacerbations.
Patients with bipolar disorder often experience frequent mood alterations that are attempted to be controlled by mood stabilizing agents and anti-psychotic agents. Both classes of medications have numerous significant side effects. Establishing that ramelteon is helpful in the sleep of patients with bipolar disorder and helpful in mood stability will increase the number of treatment options for bipolar patients.

- Pittsburgh Sleep Quality Index (PSQI) Global Score [ Time Frame: Monthly for 6 months ]Self-rated scale to measure quality of sleep via questions regarding sleep latency, duration, efficiency, disturbances, use of sleep medication, and daytime dysfunction. Scores range from 0-21, higher scores represent more significant sleep disturbance.
- Montgomery-Asberg Depression Rating Scale (MADRS) Total Score [ Time Frame: Monthly for 6 months ]10-item, standardized, well-validated scale used to measure severity of depressive symptoms; sensitive to treatment effects in depressed outpatients. Scores range from 0-60, higher scores represent more severe depressive symptoms.
- Young Mania Rating Scale (YMRS) Total Score [ Time Frame: Monthly for 6 months ]11-item standardized, well-validated scale used to measure manic symptoms; sensitive to treatment effects in manic patients. Scores range from 0-60, higher scores represent more severe manic symptoms.
- Clinical Global Impressions Bipolar Version(CGI-BP) Severity of Illness Overall Score [ Time Frame: Monthly for 6 months ]3-part (mania, depression, overall bipolar illness), physician-administered scale used to assess global illness severity; used to measure change. Each part is rated from 1-7, higher scores represent more severe mental illness. Only overall bipolar rating was used.
- Cumulative Proportion of Participants in Each Arm Surviving Without Relapse [ Time Frame: Monthly for 6 months ]Survival analysis techniques, including Kaplan Meier curves, were used to evaluate group differences in time to relapse. Relapse was defined as a medication initiation or change for manic/depressed/mixed symptoms, a hospitalization for manic/depressed/mixed symptoms, MADRS score >= 16, YMRS score > 14, and suicide risk or imminent risk of suicide. Time to relapse was measured discretely in terms of the number of assessment visits until discontinued from the study.
