OBJECTIVE: Determine the efficacy and tolerability of olanzapine/fluoxetine combination (OFC) for treatment of acute bipolar I depression compared with lamotrigine.
METHOD: The 7-week, acute phase of a randomized, double-blind study compared OFC (6/25, 6/50, 12/25, or 12/50 mg/day; N = 205) with lamotrigine ([LMG] titrated to 200 mg/day; N = 205) in patients with DSM-IV-diagnosed bipolar I disorder, depressed. The study was conducted from November 2003 to August 2004.
RESULTS: Completion rates were similar between treatments (OFC, 66.8% vs. LMG, 65.4%; p = .835). OFC-treated patients had significantly greater improvement than lamotrigine-treated patients in change from baseline across the 7-week treatment period on the Clinical Global Impressions-Severity of Illness scale (primary outcome) (p = .002, effect size = 0.26), Montgomery-Asberg Depression Rating Scale (MADRS) (p = .002, effect size = 0.24), and Young Mania Rating Scale total scores (p = .001, effect size = 0.24). Response rates did not significantly differ between groups when defined as > or = 50% reduction in MADRS score (OFC, 68.8% vs. LMG, 59.7%; p = .073). Time to response was significantly shorter for OFC-treated patients (median days [95% CI] = OFC, 17 [14 to 22] vs. LMG, 23 [21 to 34]; p = .010). There was a significant difference in incidence of "suicidal and self-injurious behavior" adverse events (OFC, 0.5% vs. LMG, 3.4%; p = .037). Somnolence, increased appetite, dry mouth, sedation, weight gain, and tremor occurred more frequently (p < .05) in OFC-treated patients than lamotrigine-treated patients. Weight, total cholesterol, and triglyceride levels were significantly elevated in OFC-treated patients compared with lamotrigine-treated patients (all p < or = .001).
CONCLUSIONS: Patients with acute bipolar I depression had statistically significantly greater improvement in depressive and manic symptoms, more treatment-emergent adverse events, greater weight gain, and some elevated metabolic factors with OFC than lamotrigine. Treatment differences were of modest size.
