Adjunctive Brexpiprazole and Functioning in Major Depressive Disorder: A Pooled Analysis of Six Randomized Studies Using the Sheehan Disability Scale.

ABSTRACT: BACKGROUND:Patients with major depressive disorder and inadequate response to antidepressant treatments may experience a prolonged loss of functioning. This post hoc analysis aimed to determine the effect of adjunctive brexpiprazole on functioning in such patients. METHODS:A pooled analysis of data from the 6-week, randomized, double-blind treatment phases of 6 studies of adjunctive brexpiprazole (2 and 3 mg/d in fixed-dose studies; 1-3 mg/d in flexible-dose studies) vs placebo in patients with major depressive disorder and inadequate response to antidepressant treatments (NCT01360645, NCT01360632, NCT02196506, NCT01727726, NCT00797966, NCT01052077). Functioning was measured by change in Sheehan Disability Scale score from baseline to week 6. RESULTS:Considering Sheehan Disability Scale mean score across all 6 studies (n = 2066 randomized), the least squares mean difference between antidepressant treatments + brexpiprazole and antidepressant treatments + placebo at week 6 was -0.40 (95% CI: -0.56, -0.23; P < .0001). Antidepressant treatments + brexpiprazole showed a greater benefit than antidepressant treatments + placebo on the social life (-0.45; -0.63, -0.27; P < .001) and family life (-0.50; -0.70, -0.31; P < .001) items but not on the work/studies item (-0.16; -0.38, 0.06; P = .16). Pooled analyses of just the (1) fixed-dose, (2) flexible-dose, and (3) Phase 3 studies showed the same pattern of benefits for antidepressant treatments + brexpiprazole. CONCLUSIONS:Brexpiprazole, as adjunct to antidepressant treatments, improved functioning in patients with major depressive disorder and inadequate response to antidepressant treatments.

Project description:ObjectiveEpisodes of major depressive disorder (MDD) characterized by high levels of anxiety symptoms are less likely to respond to some forms of antidepressant treatment (ADT). This report examines the effects of adjunctive brexpiprazole on depressive symptoms among patients with MDD and anxiety symptoms.Materials and methodsThis was a post hoc analysis of 1,171 patients from the 6-week, randomized, double-blind phases of three studies in adults with MDD and inadequate response to ADTs (NCT01360645, NCT01360632, NCT02196506). Data were pooled for brexpiprazole 2-3 mg/day and for placebo (adjunct to ADT). Montgomery-Åsberg Depression Rating Scale Total score changes were assessed in subgroups of patients with and without anxious distress (based on proxies for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria) and anxious depression (defined as a Hamilton Depression Rating Scale Anxiety/somatization factor score of ?7). Safety was assessed by the incidence of treatment-emergent adverse events (TEAEs).ResultsBenefits were seen for adjunctive brexpiprazole (compared with adjunctive placebo) in both anxiety definition subgroups. For patients with anxious distress, the least squares mean difference (95% CI) at week 6 was -3.00 (-4.29, -1.71; P<0.0001) and, for those without anxious distress, was -1.38 (-2.71, -0.05; P=0.043). For patients with anxious depression, the difference was -2.19 (-3.60, -0.78; P=0.0023), compared with -2.34 (-3.58, -1.10; P=0.0002) for those without anxious depression. The most common TEAEs among patients with anxiety symptoms receiving ADT + brexpiprazole were akathisia, headache, restlessness, somnolence, and weight increase. There were no clinically meaningful differences in the rates of these TEAEs according to the presence or absence of anxiety symptoms.ConclusionAdjunctive brexpiprazole 2-3 mg/day may be efficacious in reducing depressive symptoms, and was well tolerated, in patients with clinically relevant anxiety symptoms.

Project description:BackgroundApproximately 50% of patients with major depressive disorder do not respond adequately to their antidepressant treatment, underscoring the need for more effective treatment options. The objective of this study was to investigate the effect of adjunctive brexpiprazole on depressive symptoms in patients with major depressive disorder who were not responding to adjunctive or combination therapy of their current antidepressant treatments with several different classes of agents (NCT02012218).MethodsIn this 6-week, open-label, phase 3b study, patients with major depressive disorder who had an inadequate response to ≥1 adjunctive or combination therapy, in addition to history of ≥1 failure to monotherapy antidepressant treatment, were switched to adjunctive brexpiprazole. Efficacy was assessed by change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale total score. Patient functioning was assessed using the Sheehan Disability Scale and the Cognitive and Physical Functioning Questionnaire. Safety and tolerability were also assessed.ResultsA total of 51/61 (83.6%) patients completed 6 weeks of treatment with adjunctive brexpiprazole. Improvements in depressive symptoms were observed (least squares mean change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale total score, -17.3 [P < .0001]) as well as improvements in general and cognitive functioning (mean changes from baseline to week 6: Sheehan Disability Scale, -3.1 [P < .0001]; Massachusetts General Hospital-Cognitive and Physical Functioning Questionnaire, -9.2 [P < .0001]). The most common adverse event was fatigue (14.8%); akathisia was reported by 8.2% of patients.ConclusionsIn patients with major depressive disorder who had switched to open-label adjunctive brexpiprazole following inadequate response to previous adjunctive or combination therapy, improvements were observed in depressive symptoms, general functioning, cognitive function, and energy/alertness.

Project description:BACKGROUND:Patients with major depressive disorder (MDD) who fail to achieve complete remission with antidepressant therapy may benefit from augmentation therapy with an atypical antipsychotic. METHOD:A pooled analysis was performed on 2 identical 14-week studies (8-week prospective antidepressant therapy treatment phase followed by 6-week randomized double-blind phase) evaluating the efficacy of adjunctive aripiprazole (2-20 mg/day) in DSM-IV-TR-defined MDD patients with an inadequate response to antidepressant therapy. Primary efficacy endpoint was the mean change in Montgomery-Asberg Depression Rating Scale (MADRS) total score from end of the prospective phase (week 8) to end of randomized phase (week 14, last observation carried forward). Subgroup analyses were performed. The key secondary endpoint was mean change in Sheehan Disability Scale (SDS) mean score. RESULTS:At endpoint, mean change in MADRS total score was significantly greater with adjunctive aripiprazole (-8.7) than with adjunctive placebo (-5.7; p < .001). Except for a differential treatment-by-sex interaction, change in MADRS total scores were consistently greater with adjunctive aripiprazole than with adjunctive placebo, regardless of race, age, episode duration, prior antidepressant therapy response, number of historical treatment failures, severity of depressive symptoms, and antidepressant. At endpoint, MADRS remission rates were significantly greater with adjunctive aripiprazole than with placebo (25.7% vs. 15.4%; p < .001). Adjunctive aripiprazole also demonstrated significantly greater improvements in mean change from baseline in SDS total score than adjunctive placebo (-1.2 vs. -0.6; p = .001). CONCLUSION:Augmentation of antidepressant therapy with the atypical antipsychotic aripiprazole resulted in significant efficacy benefits across a range of subgroups of patients with MDD. Further study of a treatment-by-sex interaction is needed. TRIAL REGISTRATION:www.clinicaltrials.gov Identifiers: NCT00095823 and NCT00095758.

Project description:ObjectivePatients with major depressive disorder (MDD) with inadequate response to antidepressant treatment (ADT) may suffer a prolonged loss of functioning. This review aimed to determine if self-rated functional measures are informative in randomized placebo-controlled studies of adjunctive therapy in patients with MDD and inadequate response to ADT.MethodsThis was a systematic literature review of articles in any language from the MEDLINE database published between January 1990 and March 2017. Eligible studies met the following criteria: patients with MDD; inadequate response to at least one ADT; adjunctive therapy (pharmacological or otherwise) to ADT; placebo control group; randomized controlled trial or a post hoc analysis of a randomized controlled trial; reported a self-rated functioning scale. Study characteristics and functioning efficacy data were extracted.ResultsA total of 2,090 discrete records were screened, 293 full-text articles were assessed for eligibility, and 26 studies were included. All studies were acute (6-12 weeks) except for one 52-week study. The only self-rated functioning scale used in the included studies was the Sheehan Disability Scale (SDS). Of the 13 adjunctive agents identified, aripiprazole, brexpiprazole, edivoxetine, and risperidone improved functioning versus placebo (p<0.05), as measured by the SDS total or mean score. On the SDS "work/studies" item, only aripiprazole had a statistically significant benefit, in one study out of four. Thus, where a benefit was observed on the SDS total or mean, this was generally driven by improvement on the "social life" and "family life" items. A limitation of the review is that it only considered published literature from one database.ConclusionThe SDS, a self-rated functional measure, is informative in acute randomized placebo-controlled studies of adjunctive therapy in patients with MDD and inadequate response to ADT. However, the item that measures work performance may be less relevant to this population than the items that measure social and family life.
