The authors evaluated the efficacy and safety of adjunctive aripiprazole in bipolar I patients with mania partially nonresponsive to lithium/valproate monotherapy.
This multicenter, randomized, placebo-controlled study included outpatients experiencing a manic or mixed episode (with or without psychotic features). Patients with partial nonresponse to lithium/valproate monotherapy (defined as a Young Mania Rating Scale total score >/=16 at the end of phases 1 and 2, with a decrease of </=25% between phases) with target serum concentrations of lithium (0.6-1.0 mmol/liter) or valproate (50-125 mug/ml) were randomly assigned in a 2:1 ratio to adjunctive aripiprazole (N=253; 15 or 30 mg/day) or placebo (N=131) for 6 weeks.
Mean improvement from baseline in Young Mania Rating Scale total score at week 6 (primary endpoint) was significantly greater with aripiprazole (-13.3) than with placebo (-10.7). Significant improvements in Young Mania Rating Scale total score with aripiprazole versus placebo occurred from week 1 onward. In addition, the mean improvement in Clinical Global Impression Bipolar Version (CGI-BP) severity of illness (mania) score from baseline to week 6 was significantly greater with aripiprazole (-1.9) than with placebo (-1.6). Discontinuation rates due to adverse events were higher with aripiprazole than with placebo (9% versus 5%, respectively). Akathisia was the most frequently reported extrapyramidal symptom-related adverse event and occurred significantly more frequently among those receiving aripiprazole (18.6%) than among those receiving placebo (5.4%). There were no significant differences between treatments in weight change from baseline to week 6 (+0.55 kg and +0.23 kg for aripiprazole and placebo, respectively; last observation carried forward).
Adjunctive aripiprazole therapy showed significant improvements in mania symptoms as early as week 1 and demonstrated a tolerability profile similar to that of monotherapy studies.
作者评估了阿立哌唑辅助治疗对锂盐/丙戊酸盐单药治疗部分反应不佳的双相I型躁狂症患者的疗效和安全性。
这项多中心、随机、安慰剂对照研究纳入了正在经历躁狂或混合发作(伴有或不伴有精神病性特征)的门诊患者。对锂盐/丙戊酸盐单药治疗部分反应不佳(定义为在第1和第2阶段结束时杨氏躁狂评定量表总分≥16,且两阶段间降低幅度≤25%)且锂盐目标血清浓度为(0.6 - 1.0 mmol/升)或丙戊酸盐目标血清浓度为(50 - 125 μg/ml)的患者,以2:1的比例随机分配接受阿立哌唑辅助治疗(N = 253;15或30毫克/天)或安慰剂(N = 131),为期6周。
在第6周(主要终点)时,阿立哌唑组(-13.3)的杨氏躁狂评定量表总分较基线的平均改善幅度显著大于安慰剂组(-10.7)。从第1周起,阿立哌唑组与安慰剂组相比,杨氏躁狂评定量表总分有显著改善。此外,从基线到第6周,阿立哌唑组(-1.9)的临床总体印象双相版(CGI - BP)疾病严重程度(躁狂)评分较基线的平均改善幅度显著大于安慰剂组(-1.6)。因不良事件导致停药的发生率,阿立哌唑组高于安慰剂组(分别为9%和5%)。静坐不能是最常报告的锥体外系症状相关不良事件,接受阿立哌唑治疗的患者中发生率(18.6%)显著高于接受安慰剂治疗的患者(5.4%)。从基线到第6周,两组体重变化无显著差异(阿立哌唑组和安慰剂组分别增加0.55千克和0.23千克;采用末次观察结转法)。
阿立哌唑辅助治疗早在第1周就显示出躁狂症状有显著改善,且耐受性与单药治疗研究相似。
