AbstractIntroduction: Once-daily extended release quetiapine fumarate (quetiapine XR) monotherapy was evaluated in major depressive disorder (MDD).Method: This was an 8-week (6-week randomized-phase; 2-week drug-discontinuation/tapering phase), double-blind, parallel-group, placebo-controlled study. The primary outcome measure was Montgomery-Åsberg Depression Rating Scale (MADRS) total score randomization-to-Week 6 change. Other assessments included the Hamilton Rating Scale for Depression, the Hamilton Rating Scale for Anxiety, and adverse events (AEs).Results: 723 patients were randomized: 182, 178, 179, and 184 to quetiapine XR 50, 150, 300 mg/day, and placebo, respectively. At Week 6, significant reductions occurred in MADRS score with quetiapine XR 50 mg/day (−13.56; P<.05), 150 mg/day (−14.50; P<.01) and 300 mg/day (−14.18; P<.01) versus placebo (−11.07); at Day 4, reductions for quetiapine XR (titrated to 50 or 150 mg/day according to dose group) versus placebo (−2.9) were: −4.7 (P<.01), −5.2 (P<.001), and −5.1 (P<.001), respectively. At endpoint, MADRS response (≥50% reduction in score) was 42.7% (P<.01), 51.2% (P<.001), and 44.9% (P≤.001) for quetiapine XR 50, 150, and 300 mg/day, respectively; 30.3% for placebo. Overall, quetiapine XR 150 mg/day provided consistently more positive secondary efficacy results than 50 mg/day and 300 mg/day versus placebo. The most common AEs in quetiapine XR-treated patients were dry mouth, sedation, somnolence, headache, and dizziness.Conclusion: In patients with MDD, quetiapine XR monotherapy (50/150/300 mg/day) is effective in reducing depressive symptoms, with improvement from Day 4 onwards. Safety and tolerability were consistent with the known profile of quetiapine.

Abstract Effects of once-daily extended-release quetiapine fumarate (quetiapine XR) monotherapy on sleep quality and disturbance in patients with major depressive disorder (MDD) were evaluated. Pooled data from four 6- or 8-wk placebo-controlled quetiapine XR (50–300 mg/d) monotherapy studies (D1448C00001; D1448C00002; D1448C00003; D1448C00004) were analysed. Primary efficacy end-point was change from randomization in Montgomery Åsberg Depression Rating Scale (MADRS) score. Post hoc analyses of secondary end-points were conducted for change from randomization in: MADRS item 4 (reduced sleep); Hamilton Rating Scale for Depression (HAMD) items 4 (insomnia-early), 5 (insomnia-middle), 6 (insomnia-late) and sleep disturbance factor (items 4 + 5+6) scores; Pittsburgh Sleep Quality Index (PSQI) global scores. MADRS total score change was also evaluated in patients experiencing high and low baseline sleep disturbance (HAMD sleep disturbance factor scores ⩾4 and < 4, respectively). In total, 1808 patients were randomized to quetiapine XR or placebo across four studies. At last assessment, quetiapine XR reduced MADRS item 4, HAMD items 4, 5 and 6, HAMD sleep disturbance factor score and PSQI global scores from baseline vs. placebo (p < 0.001). For those experiencing high sleep disturbance (n = 865, quetiapine XR; n = 514, placebo), quetiapine XR improved MADRS total score vs. placebo at all visits (p < 0.001). For those with low sleep disturbance (n = 252, quetiapine XR; n = 121, placebo), quetiapine XR improved MADRS total score vs. placebo at weeks 2 (p < 0.001), 4 and 6 (both p < 0.05). In conclusion, quetiapine XR (50–300 mg/d) monotherapy improved symptoms of sleep disturbance vs. placebo in patients with MDD, including those with either high or low baseline sleep disturbance levels.
