Efficacy of asenapine in manic episodes with depressive symptoms: A review of post-hoc analyses

Young, Allan H ; Eberhard, Jonas LU and Weiller, Emmanuelle (2013) In International Journal of Psychiatry in Clinical Practice 17(Suppl 2). p.36-37
Abstract
Background: Manic episodes with depressive symptoms represent a severe presentation of bipolar disorder. The effi-cacy of drugs shown useful for pure mania is largely unproven in the subset of patients with depressive symptoms. We reviewed different post-hoc analyses evaluating asenapine's effects in patients experiencing depressive symptoms during manic episodes. Methods: Different post-hoc analyses have been conducted using pooled data of two 3-week, randomized, placebo-and olanzapine-controlled trials. 1,2 Different definitions have been used to ascertain the presence of clinically relevant depressive symptoms at baseline: MADRS total score ≥ 20, CGI-BP-D scale severity score ≥ 4, DSM-IV mixed episode; 3,4 DSM-IV mixed episode with...

Background: Manic episodes with depressive symptoms represent a severe presentation of bipolar disorder. The effi-cacy of drugs shown useful for pure mania is largely unproven in the subset of patients with depressive symptoms. We reviewed different post-hoc analyses evaluating asenapine's effects in patients experiencing depressive symptoms during manic episodes. Methods: Different post-hoc analyses have been conducted using pooled data of two 3-week, randomized, placebo-and olanzapine-controlled trials. 1,2 Different definitions have been used to ascertain the presence of clinically relevant depressive symptoms at baseline: MADRS total score ≥ 20, CGI-BP-D scale severity score ≥ 4, DSM-IV mixed episode; 3,4 DSM-IV mixed episode with MADRS total score ≥ 20; 5 DSM-5 mixed features using different severity cut offs. 6 For each population, asenapine and olanzapine were compared with placebo on different depression endpoint (remission rates: MADRS ≤ 12, mean change in MADRS total score). Effect on manic symptoms was also assessed in some populations (remission rates: YMRS ≤ 12, mean change in YMRS total score) end points. Results: In all populations, asenapine was significantly superior to placebo at days 7 and 21 in reducing depressive symptoms and significantly superior to olanzapine at day 7. In a few populations, olanzapine also tended to improve depressive symptoms at day 21. Asenapine significantly improved manic symptoms as compared to placebo as early as day 2 in patients with DSM-IV mixed episodes or DSM-5 mixed features, and was significantly superior to olanzapine at day 2 in patients with the most severe depressive symptoms. Olanzapine did not separate from placebo in reducing manic symptoms severity. Conclusion: In all post-hoc analyses asenapine signifi-cantly improved both manic and depressive symptoms in bipolar patients experiencing manic episodes with depressive symptoms. Anti-manic agents appear to have differential efficacy in people who experience depressive symptoms during a manic episode. (Less)
