The ARIQUELI study: potentiation of quetiapine in bipolar I nonresponders with lithium versus aripiprazole.

ABSTRACT: The treatment of bipolar disorder (BD) remains a challenge due to the complexity of the disease. Current guidelines represent an effort to assist clinicians in routine practice but have several limitations, particularly concerning long-term treatment. The ARIQUELI (efficacy and tolerability of the combination of lithium or aripiprazole in young bipolar non or partial responders to quetiapine monotherapy) study aims to evaluate two different augmentation strategies for quetiapine nonresponders or partial responders in acute and maintenance phases of BD treatment.The ARIQUELI study is a single-site, parallel-group, randomized, outcome assessor-blinded trial. BD I patients according to the DSM-IV-TR, in depressive, manic/hypomanic or mixed episode, aged 18 to 40 years, are eligible. After diagnostic assessments, patients initiated treatment in phase I with quetiapine. Nonresponders or partial responders after 8 weeks are allocated into one of two groups, potentiated with either lithium (0.5 to 0.8 mEq/l) or aripiprazole (10 or 15 mg). Patients will be followed up for 8 weeks in phase I (acute treatment), 6 months in phase II (continuation treatment) and 12 months in phase III (maintenance treatment). Outcome assessors are blinded to the treatment. The primary outcome is the evaluation of changes in mean scores on the CGI-BP-M between baseline and the endpoint at the end of each study phase.The ARIQUELI study is currently in progress, with patients undergoing acute treatment (phase I), potentiation (phase II) and maintenance (phase III). The study will be extended until January 2015. Trials comparing lithium and aripiprazole with potentiate treatment in young BD I nonresponders to quetiapine in monotherapy can provide relevant information on the safety of these drugs in clinical practice. Long-term treatment is an issue of great importance and should be evaluated further through more in-depth studies given that BD is a chronic disease.ClinicalTrials.gov identifier: NCT01710163.

Project description:Metabolic risk factors, termed metabolic syndrome, which include obesity, diabetes, dyslipidemia, and hypertension, are more common in patients with bipolar disorder than in the general population. Moreover, medications used to treat bipolar disorder carry some risk of worsening metabolic parameters.The study was conducted at 46 study centers in the United States, although only 31 study centers enrolled patients in the 40-week extension phase. Patients with acute bipolar I mania, manic or mixed (DSM-IV-TR criteria; Young Mania Rating Scale score ? 20), who required hospitalization were randomly assigned to double-blind aripiprazole (15-30 mg/d), lithium (900-1500 mg/d), or placebo for 3 weeks. Patients treated with aripiprazole or lithium continued treatment to week 12, after which they could enter a double-blind 40-week extension phase. Patients were enrolled in the 12-week acute treatment phase between April 2004 and July 2006; the first patient entered extension treatment in October 2004, and the last patient completed treatment in May 2007. Changes in metabolic parameters were compared between patients treated with aripiprazole or lithium for up to 52 weeks using last observation carried forward and analysis of covariance. Analysis stratified by baseline body mass index (BMI) was also conducted.Modest increases in body weight were observed in both groups: +0.97 kg (2.1 lb) for aripiprazole (n = 127) and + 0.74 (1.6 lb) for lithium (n = 136), P = .60. A significant difference in body weight increase was observed only among patients with a BMI < 25: + 2.66 kg (5.9 lb) for aripiprazole (n = 35) and + 0.40 kg (0.9 lb) for lithium (n = 37), P = .02. Mean changes from baseline to week 52 in fasting levels of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, plasma glucose, triglycerides, or insulin (last observation carried forward) were small in both aripiprazole and lithium treatment groups; no significant differences were observed. Mean laboratory values were within the normal or borderline range for both treatment groups across all BMI categories.Comparably modest and similar changes in metabolic parameters were observed in patients with bipolar disorder treated for up to 1 year with either lithium or aripiprazole.clinicaltrials.gov Identifier: NCT00095511.
