Aripiprazole augmentation in major depressive disorder: a double-blind, placebo-controlled study in patients with inadequate response to antidepressants.
INTRODUCTION Effective management of  major depressive disorder ( MDD ) continues to be a challenging task for psychiatrists and primary care physicians . This trial evaluated the efficacy and safety of adjunctive aripiprazole versus antidepressant monotherapy in patients with MDD and independently replicated the positive findings of two similar trials . METHODS Patients ( N=1,147 ) with MDD experiencing a major depressive episode and a history of inadequate response to antidepressant monotherapy were enrolled ( week 0 ) ; 827 received single-blind adjunctive placebo plus open-label antidepressant ( escitalopram , fluoxetine , paroxetine controlled release , sertraline , or venlafaxine extended release ) for 8 weeks to confirm inadequate response to antidepressants ; 349 patients with inadequate response were r and omized ( 1:1 ) to double-blind , adjunctive placebo ( n=172 ) or adjunctive aripiprazole ( n=177 ; 2 - 20 mg/day ) . Primary outcome was the mean change in Montgomery-Asberg Depression Rating Scale ( MADRS ) Total score from baseline ( week 8) to endpoint ( week 14 ) . RESULTS Clinical ly significant improvements in depressive symptoms as assessed by decreases in the MADRS Total score were greater with adjunctive aripiprazole ( -10.1 ) than placebo ( -6.4 ; P<.001 ) . Remission rates were greater for adjunctive aripiprazole than for adjunctive placebo ( week 14 , 36.8 % vs 18.9 % ; P<.001 ) . Completion rates with adjunctive aripiprazole and placebo were high ( 83 % vs. 87 % ) and discontinuations due to adverse events were low ( 6.2 % vs 1.7 % ) . CONCLUSION For some patients with MDD who do not obtain adequate symptom relief with antidepressant monotherapy , adjunctive therapies can significantly improve depressive symptoms . As reported , adjunctive aripiprazole was associated with a two-fold higher remission rate than adjunctive placebo . This , and previous studies , have shown that discontinuations due to adverse events were low and completion rates were high , and has indicated that both antidepressant and aripiprazole in combination were relatively well-tolerated and safe . This is the third consecutive clinical trial , in the absence of a failed trial , to demonstrate that aripiprazole augmentation to antidepressants is an efficacious and well-tolerated treatment for patients with MDD who do not respond adequately to st and ard antidepressant monotherapy ( Clinical Trials.gov study NCT00105196 )
