Outcomes
Primary Outcome Measures
The Proportion of Patients Who Experience a Marked and Persistent Bimodal Response
A marked bimodal response is defined by the following three conditions over four consecutive weeks while on triple therapy and after three weeks of ltg:
Montgomery Asberg Depression Rating Scale (MADRS) total score of <= 19
Young Mania Rating Scale (YMRS) total score of <= 12.5
Global Assessment Scale (GAS) score >= 51
The MADRS measures the severity of a subject's depression symptoms with a possible total score ranging from 0 - 60, with higher scores indicating more severe depression.
The YMRS measures the severity of a subject's manic symptoms with a possible total score ranging from 0 - 60, with higher scores indicating more severe mania.
The GAS measures a used to rate subjectively the social, occupational, and psychological functioning of a subject and ranges in score from 0-100, with a higher score indicating better social, occupational, and psychological functioning.

5. Study Description
Brief Summary
This study will compare triple and double drug regimens in the treatment of patients with depression, hypomania, or mania.
Detailed Description
Early studies have shown lithium to produce a high percentage of satisfactory clinical response in patients with bipolar disorders. These studies, however, do not include lithium-refractory subgroups, such as bipolar II disorder patients. When the wide spectrum of bipolar disorders is considered, the lithium response rate decreases significantly. More broadly effective regimens are needed.
Participants in this study will be randomly assigned to receive either lithium plus divalproex or lithium, divalproex, and lamotrigine for 7 months. Symptoms of depression and mania will be assessed with scales and patient questionnaires.

Intervention Type
Drug
Intervention Name(s)
Lithium
Other Intervention Name(s)
Lithium Carbonate
Intervention Description
Lithium monotherapy was initiated at 450 mg once daily and titrated slowly over three weeks to a minimum blood level of 0.5 milliequivalent /L (mEq/L).
Intervention Type
Drug
Intervention Name(s)
Lamotrigine
Other Intervention Name(s)
Lamictal
Intervention Description
Patients were assigned in a one to one ratio to adjunctive lamotrigine versus placebo after stratification for illness type (bipolar I versus bipolar II), historical response to lithium (response versus non-response), and length of current exposure to combination treatment with lithium and divalproex (< 2 months versus ≥ 2 months). During Phase 2, patients were continued on the same doses of lithium and divalproex as during the open-label treatment phase and equal capsules of double-blind lamotrigine or matching placebo were gradually added per a structured dosing schedule up to a minimum dose of 150 mg and a maximum dose of 200 mg per day.
Intervention Type
Drug
Intervention Name(s)
Divalproex
Other Intervention Name(s)
Depakote, Valproic Acid
Intervention Description
Divalproex was then initiated at 250 mg twice daily and increased slowly over five weeks to a minimum blood level of 50 μg/mL.
Intervention Type

Intervention Description

During Phase 2, patients were continued on the same doses of lithium and divalproex as during the open-label treatment phase and equal capsules of double-blind lamotrigine or matching placebo were gradually added per a structured dosing schedule up to a minimum dose of 150 mg and a maximum dose of 200 mg per day.
