摘要

目的:采用一种新颖的研究设计,评估brexpiprazole辅助抗抑郁治疗(ADTs)作为维持治疗对ADT反应不足的重度抑郁症患者的疗效。方法:该研究包括8周的前瞻性治疗期,采用开放标签ADT加双盲安慰剂治疗,以及24周的随机治疗期。研究者和患者对治疗期、随机化标准和随机化时间不知情。对开放标签ADT有早期反应的患者在第6周停药。满足不良反应标准的患者被随机分配到ADT+brexpiprazole (1- 3mg /天)或ADT+安慰剂组。主要终点为完全缓解:Montgomery-Åsberg抑郁评定量表(MADRS)总分≤10,MADRS总分从随机化(即基线)至少连续8周下降≥50%。结果:初步疗效分析未显示ADT+brexpiprazole(21.4%)与ADT+placebo(24.9%)达到完全缓解的患者比例有统计学差异;优势比:0.83;p = 0.2641。从基线到第6周MADRS总分变化的次要终点显示ADT+brexpiprazole和ADT+placebo之间没有差异(-0.4;p = 0.3259)。在接受ADT+brexpiprazole的患者中,最常见的治疗不良事件(TEAE)是体重增加(9.5% vs. ADT+安慰剂组5.0%)。在随机治疗期间,ADT+brexpiprazole组的teae导致停药的发生率为6.3%,而ADT+安慰剂组为3.4%。结论:辅助布雷吡拉唑与ADT+安慰剂在完全缓解的主要终点上没有区别。在这个以前未尝试过的研究设计中,许多设计元素可能对研究结果有贡献。Brexpiprazole耐受性良好。

A randomised, placebo-controlled 24-week study evaluating adjunctive brexpiprazole in patients with major depressive disorder.

Objective: To evaluate brexpiprazole adjunctive to antidepressant therapies (ADTs) as maintenance treatment in patients with major depressive disorder with inadequate response to ADT, utilising a novel study design.

Methods: The study comprised an 8-week prospective treatment period with open-label ADT with double-blind placebo treatment and a 24-week randomised treatment period. Investigators and patients were blinded to treatment periods, randomisation criteria, and timing of randomisation. Patients with early response to open-label ADT were withdrawn at Week 6. Patients fulfilling criteria for inadequate response were randomised to ADT+brexpiprazole 1-3 mg/day, or ADT+placebo. The primary endpoint was full remission: Montgomery-Åsberg Depression Rating Scale (MADRS) total score ≤10 and ≥50% decrease from randomisation (i.e. baseline) in MADRS total score for at least 8 consecutive weeks.

Results: The primary efficacy analysis failed to show a statistically significant difference between the proportions of patients on ADT+brexpiprazole (21.4%) and ADT+placebo (24.9%) achieving full remission; odds ratio: 0.83; p=0.2641. The secondary endpoint of change from baseline to Week 6 in MADRS total score showed no difference between ADT+brexpiprazole and ADT+placebo (-0.4; p=0.3259). The most frequent treatment-emergent adverse event (TEAE) in patients receiving ADT+brexpiprazole was weight increased (9.5% vs. 5.0% in ADT+placebo). The incidence of TEAEs leading to withdrawal in the randomised treatment period was 6.3% in the ADT+brexpiprazole group and 3.4% in the ADT+placebo group.

Conclusion: Adjunctive brexpiprazole did not differentiate from ADT+placebo on the primary endpoint of full remission. A number of design elements in this previously untried study design may have contributed to the study result. Brexpiprazole was well tolerated.
