Evaluation of the effects of extended release quetiapine fumarate monotherapy on sleep disturbance in patients with major depressive disorder: a pooled analysis of four randomized acute studies

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.

Abstract Sleep disturbance is common in depression and is a risk factor for recurrence and suicide. This analysis evaluated the effects of adjunct extended-release quetiapine fumarate (quetiapine XR) on sleep disturbance and quality in patients with major depressive disorder (MDD) and an inadequate response to on-going antidepressant therapy. Pooled data from two 6-wk, randomized, double-blind, placebo-controlled trials were analysed post hoc. Patients received once-daily quetiapine XR [(150 mg/d), n = 309; (300 mg/d), n = 307] or placebo (n = 303) adjunct to on-going antidepressant therapy. Analyses included: change from randomization in Montgomery-Åsberg Depression Rating Scale (MADRS) Item 4 (reduced sleep) score; Hamilton Rating Scale for Depression (HAMD) Items 4 (insomnia-early), 5 (insomnia-middle) and 6 (insomnia-late) scores; HAMD sleep disturbance factor (Items 4+5+6); Pittsburgh Sleep Quality Index (PSQI) global score. Change in MADRS total score was also evaluated in patients stratified by HAMD sleep disturbance factor score (high ⩾4 and low < 4) at randomization. At week 6, adjunct quetiapine XR (150 and 300 mg/d) reduced MADRS Item 4, HAMD Items 4, 5 and 6, HAMD sleep disturbance factor and PSQI global scores from randomization vs. placebo (all p < 0.001). In patients with high sleep disturbance, quetiapine XR (both doses) improved depressive symptoms (MADRS total score) vs. placebo from week 1 onwards (p < 0.01). Adjunct quetiapine XR improved sleep disturbance and quality vs. placebo in patients with MDD and an inadequate response to on-going antidepressant treatment, and was effective against depressive symptoms in patients experiencing high sleep disturbance.

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.
