Randomized, Double-Blind, Placebo-Controlled Trial Demonstrates the Efficacy and Safety of Oral Aripiprazole for the Treatment of Tourette's Disorder in Children and Adolescents.

ABSTRACT: Aripiprazole modulates dopaminergic and serotonergic pathways that may play a role in the pathogenesis of Tourette's disorder (TD). This trial evaluated the efficacy and safety of oral aripiprazole in the suppression of tics in children and adolescents with TD.This phase 3, randomized, double-blind, placebo-controlled trial ( ClinicalTrials.gov , NCT01727700) recruited patients who were 7-17 years old with a diagnosis of TD from hospitals, private practices, and research clinics at 76 sites in the United States, Canada, Hungary, and Italy. Patients were randomized in a 1:1:1 ratio by using an interactive voice/web-response system to low-dose aripiprazole (5?mg/day if <50?kg; 10?mg/day if ?50?kg), high-dose aripiprazole (10?mg/day if <50?kg; 20?mg/day if ?50?kg), or placebo for 8 weeks. Randomization was stratified by region (North America or Europe) and baseline body weight (<50?kg vs. ?50?kg). The primary efficacy endpoint was mean change from baseline to week 8 in the Yale Global Tic Severity Scale Total Tic Score (YGTSS-TTS) for the intent-to-treat population.Between November 2012 and May 2013, 133 patients were recruited and randomized to low-dose aripiprazole (n?=?44), high-dose aripiprazole (n?=?45), or placebo (n?=?44). Least-squares mean treatment differences versus placebo in change from baseline to week 8 in the YGTSS-TTS were statistically significant (high dose, -9.9 [95% confidence interval, CI, -13.8 to -5.9], low dose, -6.3 [95% CI, -10.2 to -2.3]). At week 8, 69% (29/42) of patients in the low-dose and 74% (26/35) of patients in the high-dose aripiprazole groups demonstrated a Clinical Global Impression-Tourette's Syndrome improvement score of 1 (very much improved) or 2 (much improved) compared with 38% (16/42) in the placebo group. The most common adverse events (AEs) were sedation (low dose, 8/44 [18.2%], high dose, 4/45 [8.9%], placebo, 1/44 [2.3%]), somnolence (low dose, 5/44 [11.4%], high dose, 7/45 [15.6%], placebo, 1/44 [2.3%]), and fatigue (low dose, 3/44 [6.8%], high dose, 7/45 [15.6%], placebo, 0). No serious AEs or deaths occurred.This study indicates that oral aripiprazole is a safe and effective treatment for tics in children and adolescents with TD.

Project description:AimsRapid-cycling bipolar disorder is difficult to treat and associated with greater morbidity than non-rapid-cycling disease. This post hoc analysis evaluated 28 patients with rapid-cycling bipolar I disorder from a 100-week, double-blind, placebo-controlled study assessing long-term efficacy, safety and tolerability of aripiprazole in patients with bipolar I disorder (most recently manic/mixed).MethodsFollowing >or= 6 consecutive weeks' stabilisation with open-label aripiprazole, patients were randomised (1 : 1) to aripiprazole or placebo. Patients completing 26 weeks treatment without relapse could continue for a further 74 weeks. Primary end-point was time to relapse for manic, mixed or depressive symptoms, defined as discontinuation due to lack of efficacy. Safety assessments included adverse event (AE) monitoring and changes in weight and lipid, glucose and prolactin levels.ResultsOf the 28 patients (aripiprazole, n = 14; placebo, n = 14) with rapid-cycling bipolar disorder, 12 (aripiprazole, n = 7; placebo, n = 5) completed the initial 26-week treatment period and three (all aripiprazole treated) completed the 100-week, double-blind period. Time to relapse was significantly longer with aripiprazole vs. placebo at week 26 [log-rank p = 0.033; 26-week hazard ratio = 0.21 (95% CI: 0.04, 1.03)] and week 100 [log-rank p = 0.017; 100-week hazard ratio = 0.18 (95% CI: 0.04, 0.88)]. The most commonly reported AEs with aripiprazole during the 100 weeks (>or= 10% incidence and twice placebo) were anxiety (n = 4), sinusitis (n = 4), depression (n = 3) and upper respiratory infection (n = 3). One aripiprazole-treated patient discontinued due to an AE (akathisia). There were no significant between-group differences in mean changes in weight or metabolic parameters.ConclusionIn this small, post hoc subanalysis, aripiprazole maintained efficacy and was generally well tolerated in the long-term treatment of rapid-cycling bipolar disorder. Further research with prospectively designed and adequately powered trials is warranted.

Project description:BackgroundMajor depressive disorder (MDD) is a serious illness in children and adolescents. Vilazodone is a selective serotonin reuptake inhibitor approved for MDD in adults. This study evaluated the efficacy, safety, and tolerability of vilazodone in adolescent patients, ages 12-17 years, with MDD (NCT01878292).MethodsThis double-blind, randomized, placebo-controlled, parallel-group, fixed-dose study was conducted at 56 study centers in the United States and was 10 weeks in duration (a 1-week screening period, an 8-week double-blind treatment period, and a 1-week double-blind down-taper period). Outpatients with an MDD diagnosis based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria were included in the study. Clinical inclusion criteria required a Children's Depression Rating Scale-Revised (CDRS-R) total score of ≥ 40 and Clinical Global Impressions-Severity (CGI-S) score of ≥ 4. Patients were randomized 1:1:1 to 8 weeks of double-blind treatment with placebo (n = 174), vilazodone 15 mg/day (n = 175), or vilazodone 30 mg/day (n = 180). The primary and secondary efficacy parameters were change from baseline to week 8 in CDRS-R total score and CGI-S score, respectively. Safety parameters included adverse events (AEs); clinical laboratory, vital sign, and electrocardiogram parameters; and the Columbia-Suicide Severity Rating Scale.ResultsApproximately 86% of patients completed double-blind treatment. There was no statistically significant difference between vilazodone 15 mg/day or 30 mg/day and placebo in change from baseline in CDRS-R score. Change in CGI-S score was not significant after adjustment for multiple comparisons. The most common treatment-emergent AEs were nausea, upper abdominal pain, vomiting, diarrhea, nasopharyngitis, headache, and dizziness. Reports of suicidal ideation (placebo, 33.3%; vilazodone 15 mg/day, 36.0%; vilazodone 30 mg/day, 31.1%) and suicidal behavior (placebo, 1.8%; vilazodone 15 mg/day, 1.1%; vilazodone 30 mg/day, 1.1%) were similar between treatment groups. There were no deaths in the study.ConclusionsThe efficacy of vilazodone for the treatment of MDD in adolescent patients could not be confirmed in this study. Vilazodone was generally safe and well tolerated, with treatment-emergent AEs similar to those in adult patients.Clinical trial registrationNCT01878292.

Project description:BackgroundTreatment-resistant major depression is common and potentially life-threatening in elderly people, in whom little is known about the benefits and risks of augmentation pharmacotherapy. We aimed to assess whether aripiprazole is associated with a higher probability of remission than is placebo.MethodsWe did a randomised, double-blind, placebo-controlled trial at three centres in the USA and Canada to test the efficacy and safety of aripiprazole augmentation for adults aged older than 60 years with treatment-resistant depression (Montgomery Asberg Depression Rating Scale [MADRS] score of ≥15). Patients who did not achieve remission during a pre-trial with venlafaxine extended-release (150-300 mg/day) were randomly assigned (1:1) to the addition of aripiprazole (target dose 10 mg [maximum 15 mg] daily) daily or placebo for 12 weeks. The computer-generated randomisation was done in blocks and stratified by site. Only the database administrator and research pharmacists had knowledge of treatment assignment. The primary endpoint was remission, defined as an MADRS score of 10 or less (and at least 2 points below the score at the start of the randomised phase) at both of the final two consecutive visits, analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00892047.FindingsFrom July 20, 2009, to Dec 30, 2013, we recruited 468 eligible participants, 181 (39%) of whom did not remit and were randomly assigned to aripiprazole (n=91) or placebo (n=90). A greater proportion of participants in the aripiprazole group achieved remission than did those in the placebo group (40 [44%] vs 26 [29%] participants; odds ratio [OR] 2·0 [95% CI 1·1-3·7], p=0·03; number needed to treat [NNT] 6·6 [95% CI 3·5-81·8]). Akathisia was the most common adverse effect of aripiprazole (reported in 24 [26%] of 91 participants on aripiprazole vs 11 [12%] of 90 on placebo). Compared with placebo, aripiprazole was also associated with more Parkinsonism (15 [17%] of 86 vs two [2%] of 81 participants), but not with treatment-emergent suicidal ideation (13 [21%] of 61 vs 19 [29%] of 65 participants) or other measured safety variables.InterpretationIn adults aged 60 years or older who do not achieve remission from depression with a first-line antidepressant, the addition of aripiprazole is effective in achieving and sustaining remission. Tolerability concerns include the potential for akathisia and Parkinsonism.FundingNational Institute of Mental Health, UPMC Endowment in Geriatric Psychiatry, Taylor Family Institute for Innovative Psychiatric Research, National Center for Advancing Translational Sciences, and the Campbell Family Mental Health Research Institute.
