第49届欧洲糖尿病研究协会年会(EASD2013)于9月23-27日在西班牙巴塞罗那召开。当地时间9月24日上午,在“GLP-1受体激动剂的个体化选择(Individualising the choice among GLP-1 receptor agonists)”专场上,西班牙Clinica Juaneda医院Santiago Tofe Povedano博士报告的一项AWARD-3研究结果表明,对早期2型糖尿病患者,长效GLP-1受体激动剂Dulaglutide单药治疗的血糖控制疗效优于

AWARD-3研究是一项3期、随机、双盲、平行组、单药治疗研究,旨在比较2种剂量(1.5或0.75mg)的Dulaglutide(DU,礼来公司)和二甲双胍(MET)对早期2型糖尿病患者(平均病程2.6年)的疗效和安全性。
研究共纳入807例受试者,平均基线年龄(BL)为
55.6岁,
研究结果
● HbA1c较基线水平的下降幅度:两种剂量Dulaglutide在治疗26周时均优于二甲双胍,Dulaglutide 1.5mg组患者在治疗26周后HbA1c平均下降0.78%,二甲双胍组下降0.56%。在治疗52周时,Dulaglutide 1.5mg组优于优于二甲双胍。
● 治疗后HbA1c<7%的患者比例:Dulaglutide 1.5mg组为62%,Dulaglutide 0.75mg组为63%,二甲双胍组为54%。
● 治疗后HbA1c<6.5%的患者比例:Dulaglutide 1.5mg组为46%,Dulaglutide 0.75mg组为40%,二甲双胍组为30%。
● 体重减轻程度:Dulaglutide 1.5mg组在24周时体重平均减轻2.29kg,Dulaglutide 0.75mg组为1.36kg,二甲双胍组为2.22kg。
● 严重不良事件的发生率:Dulaglutide 1.5mg组为5.2%,Dulaglutide 0.75mg组为7.4%,二甲双胍组为6.0%。
● 不良事件发生率:Dulaglutide 1.5mg组为66.5%,Dulaglutide 0.75mg组为65.6%,二甲双胍组为63.4%。主要是
● 恶心、
● 在治疗52周时,记录的有症状低血糖(≤ 3.9毫摩尔/升)的发病率:Dulaglutide 1.5mg组为6.3%,Dulaglutide 0.75mg组为5.9%,二甲双胍组为4.9%。

现场讨论与点评
在现场报告结束的讨论时间中,有参会者提出质疑,该研究中使用的二甲双胍2000mg/天剂量过低,如果使用用3000mg/天的剂量,研究结果可能不会对Dulaglutide如此有利。Tofe Povedano博士表示,研究设计将二甲双胍剂量设置为2000mg/天是因为2000mg/天是早期2型糖尿病患者的标准治疗剂量。
苏格兰格拉斯哥大学格拉斯哥大学教授也分享了对该研究的感受,他表示,尽管本研究证实Dulaglutide能适度改善HbA1c控制,但其远期意义尚不明确。相反,二甲双胍具有降低心血管风险和长期的安全性证据,这些证据正是GLP-1类药物所缺乏的。且GLP-1类药物的成本和价格远高于二甲双胍。因此,本研究的结论暂时不会影响和改变指南推荐,我们尚需等待GLP-1类药物的长期数据。
研究摘要:
| Efficacy and safety of dulaglutide vs metformin in type 2 diabetes (AWARD-3) (dulaglutide与二甲双胍治疗2型糖尿病的疗效和安全性对比[AWARD-3]) |
| Background and aims: This Phase 3, randomised, double-blind, parallel-arm, monotherapy study compared the efficacy and safety of 2 doses of dulaglutide (DU), a long-acting glucagon-like peptide-1 (GLP-1) receptor agonist, to metformin (MET) in patients with early type 2 diabetes (mean 2.6 years) treated with diet and exercise alone or in combination with 1 oral antidiabetic medication (low dose for ≥3 months before screening). Materials and methods: Patients (N=807; mean baseline [BL] age, 55.6 years; HbA1c, 7.6%; weight, 92.3 kg) were randomised to once-weekly DU 1.5 or 0.75 mg or MET 1000 mg twice-daily. Primary hypothesis was DU 1.5 mg is noninferior to MET on HbA1c change from BL to 26 weeks (wks). Key secondary hypotheses were DU 1.5 mg is superior to MET, and DU 0.75 mg is noninferior and/or superior to MET. Results: Both DU doses were superior to MET at 26 wks and DU 1.5 mg was superior to MET at 52 wks as measured by HbA1c change from BL. Incidence of serious adverse events was 5.2% for DU 1.5 mg, 7.4% for DU 0.75 mg, and 6.0% for MET. The rank order of incidence of gastrointestinal-related adverse events among groups was: DU 1.5 mg >MET >DU 0.75 mg. At 52 wks, documented symptomatic hypoglycaemia (≤3.9 mmol/L) incidence was 6.3%, 5.9%, and 4.9% for DU 1.5 mg, DU 0.75 mg, and MET, respectively (overall p=0.756). Conclusion: In conclusion, both once-weekly DU doses at 26 wks and DU 1.5 mg at 52 wks demonstrated superior glycaemic control compared to MET and were well tolerated. |
