Onabotulinumtoxin A (Onabot A) was the first treatment to be approved for aesthetic indications, namely glabellar lines (GLs), crow's feet lines (CFLs), and forehead lines (FHLs), with a cumulative dose of 64 U.
The aim of this study was to conduct a meta-analysis to combine the available data for approved doses for GLs, CFLs, and FHLs to explore the effect and duration of simultaneous treatment with Onabot A.
PubMed/MEDLINE, Embase, and other national clinical trial registries were searched for randomized controlled trials from January 2010 to July 2022. The meta-analysis, trial sequential analysis, and investigator-assessed time to return to nonresponder status in GLs, CFLs, and FHLs following Onabot A were plotted to elicit a cumulative dose-adjusted response curve based on Kaplan-Meier analysis with a log-rank test.
Fourteen randomized controlled trials were eligible for quantitative analysis. A total of 8369 subjects were recruited across the trials. The meta-analysis results show that Onabot A is very effective in reducing moderate to severe GLs, CFLs, and FHLs. The cumulative Z-curve for GLs, CFLs, and FHLs also exceeds the required information size (RIS). Kaplan-Meier analysis with a log-rank test demonstrated that simultaneous treatment of GLs, CFLs, and FHLs requires 182 days (95% CI = 179, 215 days) (P < 0.00002) to return to nonresponder status.
Treatment of the upper facial expression lines with Onabot A is effective, and the approved cumulative dose of 64 U gives longer-lasting effects.
肉毒毒素 A(Onabot A)是第一种被批准用于美容适应症的治疗药物,即眉间纹(GL)、鱼尾纹(CFL)和额纹(FHL),累积剂量为 64U。
本研究旨在进行荟萃分析,将可用数据合并用于 GL、CFL 和 FHL 的批准剂量,以探讨同时使用 Onabot A 的效果和持续时间。
检索 PubMed/MEDLINE、Embase 和其他国家临床试验注册中心 2010 年 1 月至 2022 年 7 月的随机对照试验。对 GL、CFL 和 FHL 中 Onabot A 后恢复至非应答状态的时间进行荟萃分析、试验序贯分析和研究者评估,并根据 Kaplan-Meier 分析和对数秩检验绘制累积剂量调整反应曲线。
有 14 项随机对照试验符合定量分析的条件。共有 8369 名受试者参加了这些试验。荟萃分析结果表明,Onabot A 对减少中度至重度 GL、CFL 和 FHL 非常有效。GL、CFL 和 FHL 的累积 Z 曲线也超过了所需的信息量(RIS)。对数秩检验的 Kaplan-Meier 分析表明,同时治疗 GL、CFL 和 FHL 需要 182 天(95%CI=179,215 天)(P<0.00002)才能恢复至非应答状态。
用 Onabot A 治疗上面部表情纹有效,批准的 64U 累积剂量可产生更持久的效果。
