Abstract

Introduction: To investigate the efficacy and safety of Cutegel® MAX (Cutegel) in the correction of moderate-to-severe nasolabial folds (NLFS) compared to Restylane® (Restylane, control).

Methods: This study was a 52-week, multicenter, randomized, double-blinded, active-controlled clinical trial. Qualified participants with moderate-to-severe NLFs were randomly assigned in a 1:1 ratio to receive Cutegel or Restylane. For the primary efficacy endpoint, the response rate was defined as the percentage of subjects exhibiting an improvement of at least one-point based on blinded evaluation of Wrinkle Severity Rating Scale (WSRS) at 24 weeks after injection. Other secondary efficacy endpoints and treatment-emergent adverse events (TEAEs) were assessed.

Results: Of 340 subjects randomized, 317 completed the week 52 visit. In the per protocol set (PPS), the blinded evaluator-assessed response rates at week 24 were 81.17% for Cutegel versus 77.56% for Restylane (p =  0.327). The between-group treatment differences in response rates were 3.60% [95% confidence interval (CI) = (-5.39%, 12.60%)], which demonstrated the noninferiority of Cutegel. Other secondary efficacy endpoints supported this. No significant differences were observed in the occurrence of adverse events between the two groups.

Conclusion: Similar to Restylane, Cutegel was effective and well tolerated in correcting moderate-to-severe NLFs among the Chinese population.

一项为期 52 周的多中心、随机、双盲随访研究,比较了两种透明质酸填充剂在中国人群中治疗中重度鼻唇沟的疗效和安全性。
简介研究Cutegel® MAX(Cutegel)与Restylane®(Restylane,对照组)相比,在矫正中重度鼻唇沟(NLFS)方面的有效性和安全性:该研究是一项为期52周的多中心、随机、双盲、主动对照临床试验。患有中度至重度NLF的合格参与者按1:1的比例随机分配接受Cutegel或Restylane治疗。在主要疗效终点方面,反应率被定义为在注射后 24 周,根据皱纹严重程度评分量表(WSRS)的盲法评估,至少有一分改善的受试者百分比。此外,还评估了其他次要疗效终点和治疗突发不良事件(TEAEs):结果:在 340 名随机受试者中,有 317 人完成了第 52 周的检查。在按方案组(PPS)中,第24周时由盲法评估员评估的反应率为:Cutegel 81.17%,Restylane 77.56%(P = 0.327)。组间反应率差异为 3.60% [95% 置信区间 (CI) = (-5.39%, 12.60%)],这证明了 Cutegel 的非劣效性。其他次要疗效终点也证明了这一点。两组的不良反应发生率无明显差异:结论:与 Restylane 类似,Cutegel 在矫正中国人的中度至重度 NLF 方面效果显著,耐受性良好。
