摘要：

目的系统评价特泽帕肽治疗2型糖尿病(T2DM)患者的疗效及安全性。方法通过检索CNKI、万方、VIP、Pubmed、Embase及Cochrane library数据库获得符合纳入标准的随机对照研究(RCTs)。结果共纳入7篇RCTs,共7163名T2DM患者。Meta分析结果显示,5 mg、10 mg、15 mg 3种剂量的特泽帕肽降低糖化血红蛋白(HbA₁c)、减轻体重的疗效均明显优于所有对照组[胰高血糖素样肽1受体激动剂(GLP-1RA)、胰岛素、安慰剂],疗效呈剂量依赖性,随剂量增高,显示出更大的疗效,3种剂量下HbA₁c降低的幅度分别为[ $M D$ =-0.98, 95% $C I$ (-1.34, -0.62)]、[ $M D$ =-1.21, 95% $C I$ (-1.53, -0.89)]、[ $M D$ =-1.37, 95% $C I$ (-1.70, -1.03)];体重降低幅度分别为[ $M D$ =-6.05, 95% $C I$ (-8.58, -3.52)]、[ $M D$ =-8.56, 95% $C I$ (-11.14, -5.98)]、[ $M D$ =-10.60, 95% $C I$ (-13.24, -7.97)](均 $P$ <0.01)。在降低空腹血糖(FPG)方面,10 mg、15 mg两种剂量降低FPG的疗效均优于所有对照组(GLP-1RA、胰岛素、安慰剂),疗效呈剂量依赖性,FPG降低的幅度分别为[ $M D$ =-1.47, 95% $C I$ (-2.23, -0.70)]、[ $M D$ =-1.55, 95% $C I$ (-2.27,-0.83)](均 $P$ <0.01),5 mg剂量组降低FPG的疗效优于安慰剂,但5 mg特泽帕肽与对照组(GLP-1RA或胰岛素)相比,降低FPG的疗效无明显差异。在HbA₁c<7%、HbA₁c≤6.5%、HbA₁c<5.7%的达标率及体重减少≥5%、体重减轻≥10%、体重减少≥15%的比例方面也存在剂量依赖性,随剂量增加,HbA₁c达标率及体重减少的比例增加。安全性方面,特泽帕肽的低血糖发生率与GLP-1RA、安慰剂相似,但低于德谷/甘精胰岛素。在胃肠道不良反应方面,与安慰剂相比,3种剂量特泽帕肽治疗后出现胃肠道不良反应的比例均高于安慰剂。在特泽帕肽与对照组(GLP-1RA或胰岛素)的比较中,特泽帕肽10 mg、15 mg剂量治疗后出现胃肠道不良反应的比例均高于对照组(GLP-1RA或胰岛素),但是特泽帕肽5 mg与对照组相比,出现胃肠道不良反应的比例无明显差异。结论与安慰剂、GLP-1RA和胰岛素相比,特泽帕肽在降低HbA₁c、FPG、减轻体重方面具有明显的剂量依赖性优势,没有增加低血糖风险,但10 mg及15 mg特泽帕肽与胃肠道不良事件的发生率增加有关。

Abstract:

Objective To systematically evaluate the efficacy and safety of tirzepatide in the treatment of type 2 diabetes mellitus (T2DM). Methods CNKI, Wanfang, VIP, Pubmed, Embase and Cochrane Library were retrieved to collect randomized controlled trails (RCTs), which met inclusion criteria. Results Seven RCTs representing 7163 T2DM patients were included. Meta-analysis results showed that the tirzepatide 5 mg, 10 mg and 15 mg was superior to the control groups (glucagon-like peptide-1 receptor agonist [GLP-1RA], insulin and placebo) in reducing glycosylated hemoglobin A1c (HbA₁c) and weight loss. The curative effect appeared to be highly dose-dependent, it showed greater efficacy with increasing dose. The decrease of HbA₁c in the tirzepatide 5 mg, 10 mg and 15 mg was ( $M D$ =-0.98, 95% $C I$ [-1.34, -0.62], ( $M D$ =-1.21, 95% $C I$ [-1.53,-0.89]) and ( $M D$ =-1.37, 95% $C I$ [-1.70,-1.03]), respectively. The weight loss ranges were ( $M D$ =-6.05, 95% $C I$ [-8.58,-3.52]), ( $M D$ =-8.56, 95% $C I$ [-11.14, -5.98]) and ( $M D$ =-10.60, 95% $C I$ [-13.24, -7.97]) (all $P$ <0.01), respectively. The tirzepatide 10 mg and 15 mg was superior to the control groups (GLP-1RA, insulin and placebo) in reducing fasting plasma glucose (FPG). The curative effect appeared to be dose-dependent, and the extent of FPG reduction with the tirzepatide 10 mg and 15 mg was ( $M D$ =-1.47, 95% $C I$ [-2.23, -0.70]) and ( $M D$ =-1.55, 95% $C I$ [-2.27, -0.83]), (all $P$ <0.01), respectively. The tirzepatide 5 mg was more effective in reducing FPG than placebo. No difference was significant in reducing FPG between tirzepatide 5 mg and the control group (GLP-1RA or insulin). There was also a dose dependence on the compliance rate of HbA₁c<7%, HbA₁c≤6.5%, HbA₁c<5.7% and the proportion of weight loss≥5%, weight loss≥10%, weight loss≥15%. However, there was no significant in compliance rate of HbA₁c and the proportion of weight loss increased. The safety of tirzepatide in incidence of hypoglycemia was similar to that of GLP-1RA and placebo, but lower than that of degludec/glargine insulin. The proportion of gastrointestinal adverse reactions of tirzepatide 5 mg, 10 mg and 15 mg was higher than that of placebo, the proportion of gastrointestinal adverse reactions of tirzepatide 10 mg and 15 mg was higher than that of the control group (GLP-1RA or insulin), but there was no significant difference in gastrointestinal adverse reactions between the control group and tirzepatide 5 mg. Conclusion Compared with placebo, GLP-1RA and insulin, tirzepatide has significant dose-dependent advantages in reducing HbA₁c, FPG and weight loss, and does not increase the risk of hypoglycemia, but tirzepatide 10 mg and 15 mg are associated with increased incidence of gastrointestinal adverse events.
