At Screening
The subject who has a diagnose of bipolar I disorder, most recent episode depressed (296.5x) must meet the following criteria:
At Screening
The subject who has a diagnose of bipolar I disorder, most recent episode hypomanic(296.4x) or bipolar I disorder, most recent episode manic(296.5x) must meet the following criteria:

At Week 0 of First Phase (titration) If the subject's index episode is subject initial manic mood event, subject must have a minimum total score at baseline of 10 (moderate severity) on the first 11 items of the YMRS at the start of First Phase (titration). A threshold YMRS score that indicates significant manic symptoms is not required for patients who previously experienced well-documented DSM-IV-level mania or when the index episode is hypomania or when a subject's index manic or hypomanic episode is documented to have occurred within 60 days of the screening Visit.
At Week 0 of Second Phase (maintenance therapy) Each subject completing 8 to 16 weeks of open-label lamotrigine treatment in the First Phase must meet all of the following inclusion criteria to be eligible for entry into the Second Phase (maintenance therapy, randomization phase).
At Week 0 of Second Phase (maintenance therapy) Has no tolerability problem with lamotrigine at a minimum dosage of 100 mg/day during the final 2 weeks of the First Phase (titration).
At Week 0 of Second Phase (maintenance therapy) Has improved/stabilised during the First Phase (titration) as indicated by a CGI-S score of ≤3 (mildly ill). Once improved, the subject must also demonstrate sustained improvement by achieving a CGI-S score of ≤3 (mildly ill) for at least 4 consecutive weeks of treatment immediately prior to the Second Phase (maintenance therapy) (randomization).
At Week 0 of Second Phase (maintenance therapy) Has demonstrated adequate compliance with the study treatment in the First Phase (titration) (compliance rate: at least 70%).
