Quetiapine monotherapy as treatment for anxiety symptoms in patients with bipolar depression: a pooled analysis of results from 2 double-blind, randomized, placebo-controlled studies.

ABSTRACT: OBJECTIVE:To evaluate the efficacy and tolerability of quetiapine monotherapy for anxiety symptoms in patients with bipolar disorder experiencing depression in the BipOLar DEpRession (BOLDER I and II) studies. METHOD:A post hoc analysis of anxiety symptoms in 1,051 acutely depressed patients with bipolar I or II disorder (DSM-IV) from 2 double-blind, randomized, placebo-controlled 8-week studies of quetiapine (300 or 600 mg once daily) was conducted. Anxiety symptoms were assessed using Hamilton Anxiety Rating Scale (HARS) total and psychic (items 1-6, 14) and somatic (items 7-13) anxiety subscale scores (mixed-model repeated measure and last-observation-carried-forward analysis of change from baseline at each assessment). The BOLDER I study was conducted between September 2002 and October 2003, and the BOLDER II study was conducted between June 2004 and August 2005. RESULTS:Mean baseline HARS total scores were similar across the treatment groups (300 mg/d: 18.9, 600 mg/d and placebo: both 18.6). There was a significantly greater improvement from baseline in mean HARS total scores at the first evaluation (week 1) in both quetiapine groups compared with placebo (300 mg/d: -4.6, P < .001 and 600 mg/d: -4.1, P = .003 vs placebo: -2.8). These improvements were sustained through week 8 with both quetiapine doses (300 mg/d: -10.1, P < .001 and 600 mg/d: -10.5, P < .001 vs placebo: -6.9). At week 8, there was also significant improvement from baseline in HARS psychic and somatic anxiety subscale scores compared with placebo (P < .001). The baseline severity of anxiety did not impact the improvement in depressive symptoms. Common adverse events included dry mouth, sedation, somnolence, and dizziness. CONCLUSIONS:In this pooled analysis, quetiapine monotherapy was more effective than placebo and generally well tolerated for the treatment of both depressive and anxiety symptoms in patients with bipolar disorder.

Project description:ObjectiveQuetiapine is an atypical antipsychotic with demonstrated efficacy in the treatment of adolescent schizophrenia and pediatric bipolar mania. Large, placebo-controlled studies of interventions in pediatric bipolar depression are lacking. The current study investigated the efficacy and safety of quetiapine extended-release (XR) in patients 10-17 years of age, with acute bipolar depression.MethodsThis multicenter, double-blind, randomized, placebo-controlled study investigated quetiapine XR (dose range, 150-300 mg/day) in pediatric outpatients with an American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) diagnosis of bipolar I or bipolar II disorder (current or most recent episode depressed) treated for up to 8 weeks (ClinicalTrials.gov identifier: NCT00811473). The primary study outcome was mean change in Children's Depression Rating Scale-Revised (CDRS-R) total score. Secondary efficacy outcomes included CDRS-R-based response and remission rates.ResultsOf 193 patients randomized to treatment, 144 patients completed the study (75.3% of quetiapine XR group [n=70]; 74.0% of placebo group [n=74]). Least squares mean changes in CDRS-R total score at week 8 were: -29.6 (SE, 1.65) with quetiapine XR and -27.3 (SE, 1.60) with placebo, a between-treatment group difference of -2.29 (SE, 1.99; 95% CI, -6.22, 1.65; p=0.25; mixed-model for repeated measures analysis). Rates of response and remission did not differ significantly between treatment groups. The safety profile of quetiapine XR was broadly consistent with the profile reported previously in adult studies of quetiapine XR and pediatric studies of quetiapine immediate-release (IR). Potentially clinically significant elevations in clinical chemistry values included triglycerides (9.3%, quetiapine XR; 1.4%, placebo group) and thyroid stimulating hormone (4.7%, quetiapine XR; 0%, placebo group). An adverse event potentially related to diabetes mellitus occurred in 3.3% of the quetiapine XR versus no adverse events in the placebo group.ConclusionsQuetiapine XR did not demonstrate efficacy relative to placebo in this 8 week study of pediatric bipolar depression. Quetiapine XR was generally safe and well tolerated.

Project description:BACKGROUND:Symptoms of anxiety co-occur in a variety of disorders including in depressive episodes of bipolar disorder and in patients with thyrotoxicosis. Treatment of refractory bipolar disorder with supraphysiologic doses of levothyroxine (L-T4) has been shown to improve the phenotypic expression of the disorder and is associated with an increase of circulating thyroid hormones. However, it might be associated with somatic and mental adverse effects. Here we report the investigation of the influence of treatment with supraphysiologic doses of L-T4 on symptoms of anxiety in patients with refractory bipolar depression. METHODS:Post-hoc analysis from a 6-week, multi-center, randomized, double-blind, placebo-controlled study of the effects of supraphysiologic L-T4 treatment on anxiety symptoms in bipolar depression. Anxiety symptoms were measured weekly with the Hamilton anxiety/somatization factor (HASF) score of the Hamilton Depression Rating Scale (HAMD) and the State- and Trait Anxiety Inventory (STAI). RESULTS:Treatment of both groups was associated with a significant reduction in anxiety symptoms (p?<?0.001) with no statistical difference between groups (LT-4: from 5.9 (SD?=?2.0) at baseline to 3.7 (SD?=?2.4) at study end; placebo: from 6.1 (SD?=?2.4) at baseline to 4.4 (SD?=?2.8) at study end; p?=?0.717). Severity of anxiety at baseline did not show a statistically significant correlation to the antidepressive effect of treatment with supraphysiologic doses of L-T4 (p?=?0.811). Gender did not show an influence on the reduction of anxiety symptoms (females: from 5.6 (SD?=?1.7) at baseline to 3.5 (SD?=?2.4) at study end; males: from 6.1 (SD?=?2.3) at baseline to 4.0 (SD?=?2.4) at study end; p?=?0.877). CONCLUSIONS:This study failed to detect a difference in change of anxiety between bipolar depressed patients treated with supraphysiologic doses of L-T4 or placebo. Comorbid anxiety symptoms should not be considered a limitation for the administration of supraphysiologic doses of L-T4 refractory bipolar depressed patients.

Project description:Rapid-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).Following >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.Of 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.In 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.
