Quetiapine monotherapy in bipolar II depression: combined data from four large, randomized studies.

Young AH, Calabrese JR, Gustafsson U, Berk M, McElroy SL, Thase ME, Suppes T, Earley W - Int J Bipolar Disord (2013)

Bottom Line: Improvements in mean MADRS total scores from baseline to week 8 were significantly greater with quetiapine 300 and 600 mg/day (-15.58 [n = 283] and -14.88 [n = 289]; p < 0.001) compared with placebo (-11.61 [n = 204]).Common adverse events associated with quetiapine (both doses) included dry mouth, somnolence, sedation, dizziness, and headache.Quetiapine monotherapy demonstrated significant efficacy compared with placebo and was generally well tolerated in the treatment of bipolar II depression.

ABSTRACT

Background: Despite being present in up to 1% of the population, few controlled trials have examined the efficacy of treatments for bipolar II depression. Pooled data are presented from four placebo-controlled studies (BOLDER I [5077US/0049] and II [D1447C00135]; EMBOLDEN I [D1447C00001] and II [D1447C00134]) that evaluated the efficacy of quetiapine monotherapy for depressive episodes in patients with bipolar II disorder.

Methods: All studies included an 8-week, double-blind treatment phase in which patients were randomly assigned to treatment with quetiapine 300 mg/day, quetiapine 600 mg/day, or placebo. Outcome measures included the change from baseline in MADRS total score at week 8, effect sizes, and MADRS response and remission rates.

Results and discussion: Improvements in mean MADRS total scores from baseline to week 8 were significantly greater with quetiapine 300 and 600 mg/day (-15.58 [n = 283] and -14.88 [n = 289]; p < 0.001) compared with placebo (-11.61 [n = 204]). The MADRS effect sizes were 0.44 for quetiapine 300 mg/day and 0.47 for 600 mg/day (p < 0.001 vs placebo). Significantly higher proportions of patients receiving quetiapine, at both doses, than placebo-treated patients achieved response and remission at week 8 (p < 0.01). Common adverse events associated with quetiapine (both doses) included dry mouth, somnolence, sedation, dizziness, and headache. Rates of mania and hypomania were similar for quetiapine and placebo. Quetiapine monotherapy demonstrated significant efficacy compared with placebo and was generally well tolerated in the treatment of bipolar II depression.

Fig2: Mean change from baseline to week 8 in MADRS total score (ITT population; LOCF).

Mentions: Among patients with bipolar II disorder, treatment with quetiapine resulted in significantly greater improvements in depression symptoms compared with placebo, as measured by mean change in MADRS total score from baseline to week 8 (mean [SE] −15.58 [0.62] and −14.88 [0.62] for quetiapine 300 and 600 mg/day, respectively, vs−11.61 [0.70] for placebo; LOCF; p < 0.001, both doses). Significant separation from placebo was observed from week 1 for both doses of quetiapine and was maintained through week 8 (Figure 2). Effect sizes, based on MADRS scores, were moderate for both quetiapine 300 and 600 mg/day (MMRM: 0.44 and 0.47, respectively, p < 0.001 vs placebo; Figure 3). The effect sizes in the bipolar I population in the four trials were 0.58 for quetiapine 300 mg/day and 0.64 for quetiapine 600 mg/day (Figure 3).Figure 2
