N2 - 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.
