Effects of adjunctive aripiprazole on sexual functioning in patients with major depressive disorder and an inadequate response to standard antidepressant monotherapy: a post hoc analysis of 3 randomized, double-blind, placebo-controlled studies.

ABSTRACT: To investigate the specific effect of adjunctive aripiprazole on sexual function in patients with major depressive disorder and a history of an inadequate response to antidepressant medication by controlling for improvement in depressive symptoms as measured by improvement in Montgomery-Asberg Depression Rating Scale (MADRS) total scores.For this post hoc analysis, data were pooled from 3 multicenter, randomized, double-blind, placebo-controlled aripiprazole augmentation studies (CN138-139: June 2004-April 2006; CN138-163: September 2004-December 2006; and CN138-165: March 2005-April 2008). Outpatients who met DSM-IV-TR criteria for a major depressive episode that had lasted ?8 weeks with an inadequate response to prospective antidepressant treatment were randomized to adjunctive aripiprazole or placebo for 6 weeks. Sexual functioning was assessed using the Massachusetts General Hospital Sexual Functioning Inventory (MGH-SFI). To assess whether adjunctive aripiprazole improves sexual functioning directly, rather than as an indirect effect of improvement in depression symptoms, the mean change in MGH-SFI item scores and overall improvement scores was assessed using analysis of covariance, with double-blind baseline and change in MADRS total score as covariates. Correlations between MGH-SFI items and MADRS total score and prolactin levels were also assessed.The analysis included 1,092 subjects (n=737 female and n=355 male). In the total population, adjunctive aripiprazole demonstrated statistically significant greater improvements versus placebo on the MGH-SFI item "interest in sex" (-0.34 vs -0.18, P<.05). In males, no significant treatment differences were observed. In females, improvements in sexual functioning with adjunctive aripiprazole versus placebo were found on the MGH-SFI items "interest in sex" (-0.41 vs -0.21, P<.05) and "sexual satisfaction" (-0.44 vs -0.25, P<.05).Aripiprazole adjunctive to antidepressant treatment can have some beneficial effects on sexual functioning in patients with major depressive disorder who respond inadequately to standard antidepressant treatment; the benefits in women were specific to sexual interest and satisfaction and were independent of the improvement in depressive symptoms.clinicaltrials.gov Identifiers: NCT00095823, NCT00095758, and NCT00105196.

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:ObjectiveTo evaluate the safety and tolerability of aripiprazole adjunctive to standard antidepressant therapy (ADT) for patients with major depressive disorder (DSM-IV-TR criteria).MethodData from 2 identical studies of aripiprazole augmentation (8 weeks of prospective ADT treatment followed by 6 weeks of randomized double-blind adjunctive treatment) were pooled. The incidence of treatment-emergent adverse events (TEAEs) and weight, electrocardiogram (ECG), and laboratory measurements were assessed during the 6-week phase, including time course, severity, resolution, and predictors. The studies were conducted from June 2004 to April 2006 and September 2004 to December 2006.ResultsThe safety analysis included 737 outpatients (aripiprazole, n = 371; placebo, n = 366). The majority of patients completed the trials (aripiprazole, 86%; placebo, 88%). Common TEAEs (≥ 5% and twice the placebo rate) with aripiprazole were akathisia (25%), restlessness (12%), insomnia (8%), fatigue (8%), blurred vision (6%), and constipation (5%). Most TEAEs were of mild to moderate severity (aripiprazole, 89%; placebo, 95%). TEAE rates in the aripiprazole and placebo groups were not affected by ADT, age, or gender. Discontinuation due to TEAEs was low (aripiprazole, 3%; placebo, 1%). Mean weight change was higher with aripiprazole versus placebo (1.73 kg vs 0.38 kg, P < .001). At endpoint, clinical laboratory parameters, vital signs, and ECG indices (including QT(c) interval) were similar between groups. Akathisia with aripiprazole generally occurred in the first 3 weeks (76%), was of mild to moderate severity (92%), and led to discontinuation in 3 patients (0.8%). Within the aripiprazole group, age (18-40 years) was the only positive predictor for akathisia.ConclusionsIn this short-term post hoc analysis, aripiprazole as augmentation to ADT demonstrated a safety and tolerability profile similar to that in monotherapy studies in other psychiatric populations. Controlled long-term safety and efficacy data of aripiprazole as adjunctive to ADT are warranted.Trial registrationclinicaltrials.gov Identifiers: NCT00095823 (CN138-139) and NCT00095758 (CN138-163).

Project description:BackgroundPatients with major depressive disorder (MDD) who fail to achieve complete remission with antidepressant therapy may benefit from augmentation therapy with an atypical antipsychotic.MethodA 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.ResultsAt 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).ConclusionAugmentation 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 registrationwww.clinicaltrials.gov Identifiers: NCT00095823 and NCT00095758.

Project description:BackgroundClinical practice guidelines support efforts to improve functioning in patients with schizophrenia. Discrepancies in the perception of cognitive status between clinicians, patients with schizophrenia, and their caregivers have been associated with impaired functional abilities in patients; medication side effects might worsen both cognition and daily functioning. We assessed daily/social functioning and cognition in stable patients with schizophrenia who switched to the long-acting injectable (LAI) antipsychotic aripiprazole lauroxil (AL).MethodsClinically stable adults with residual symptoms of schizophrenia or intolerance following three or more doses of paliperidone palmitate or risperidone LAI were switched to flexibly dosed open-label AL treatment (441mg, 662mg, or 882mg every 4 weeks or 882mg every 6 weeks) for six months (ClinicalTrials.gov identifier: NCT02634320). Daily/social functioning was assessed using the Personal and Social Performance Scale (PSP); total and subscale scores were summarized using descriptive statistics. The cognitive status of patients was assessed using the New York Assessment of Adverse Cognitive Effects of Neuropsychiatric Treatment (NY-AACENT) at baseline and Month 6 or early termination, providing patient, caregiver, and clinician perspectives. A post hoc analysis assessed level of agreement in ratings of cognitive status among respondents, evaluated at baseline and last assessment, using weighted kappa coefficients (0.01-0.20, slight agreement; 0.21-0.40, fair agreement; 0.41-0.60, moderate agreement; 0.61-0.80, substantial agreement.).ResultsAll 51 enrolled patients received one or more AL doses; 35 completed the study, and 45 contributed data at last assessment. Mean age was 40.6 years; 72.5 percent of patients were male. Based on PSP total score, functioning was maintained from baseline (mean [standard deviation (SD)]: 55.1 [10.5]) through six months of AL treatment (mean [SD]: 57.7 [13.2]). Proportions of patients rating personal and social functioning issues as "not present" or "mild" remained stable between baseline and Month 6 for each PSP subscale. At baseline (n=50), cognitive difficulties were most commonly rated "not present" or "mild" in all NY-AACENT domains by patients (58-86% across domains), clinicians (62-94%), and caregivers (50-92%), and these rates were maintained or increased at last assessment for all reporters. Weighted kappa coefficients indicated fair-to-substantial agreement between patients and clinicians across domains at last assessment (0.32-0.64; baseline: 0.14-0.55); patient-caregiver agreement ranged from 0.07 to 0.50 at last assessment (baseline: 0.25-0.60).ConclusionIn clinically stable patients with schizophrenia who initiated AL, self-reported functioning was maintained over six months of treatment. Clinician-, caregiver-, and patient-reported cognitive function was stable at baseline and maintained in all NY-AACENT domains; patient-clinician agreement on level of cognitive impairment increased over six months of treatment with AL.
