摘  要:目的:观察人体对单次给予冻干重组胰高血糖素样肽一1受体激动剂(rE-4)的安全性和耐受性,同时考察rE-4在健康人体中的药动学特征。方法:采用随机、双盲、安慰剂对照、单剂量递增设计,共46例受试者参加研究。分为2.5,5,10,12.5,15,17.5μg共6个剂量组,每例受试者只接受一个剂量试验。对其中2.5~15μg5个剂量组同时进行药动学研究。结果:单剂量皮下注射2.5,5,10,12.5,15μgrE-4的主平均药动学参数为:C…为(119.96±25.09),(217.46±37.22),(388.15±34.16),(426.05±34.83),(514.07±41.57)pg·mL-1;Tmax为(0.81±0.13),(0.67±0.13),(1.13±0.44),(1.29±0.46),(1.08±0.34)h;t1/2为(1.09±0.15),(1.70±0.32),(1.90±0.64),(1.94±0.15),(1.83±0.36)h;AUC0。。为(250.88±32.34),(683.85±137.08),(1177.37±119.30),(1528.96±179.37),(1739.16±137.94)h·pg·mL-1。参加本试验的46例受试者中,安慰剂组12例受试者均未发生不良事件,接受了rE-4的34例受试者中,有11例受试者出现13例次不良事件。13例次不良事件中,1例次为中度(15μg剂量组1名受试者血糖降低),其余均为轻度。结论:中国健康受试者单次皮下注射试验药物rE-4在2.5~15μg范围内,Cmax随剂量增加的比例小于剂量增加的比例,AUC0-1随剂量成线性增加,其他主药动学参数平均值大致相同。在2.5~17.5μg范围内对参加本研究的中国健康受试者是安全的。Objectives: To observe the safety and tolerability of single dose of lyophilized recombinant glu- cagon-like peptide-1 receptor agonist (rE-4) and study its pharmacokinetic characteristics in healthy subjects. Methods: This was a randomized, double blind, placebo controlled, single dose escalation subjects were divided into one of 2.5,5,10,12.5,15,17.5 μg dose groups, and each subject ministration. Pharmacokinetic study was carried out in 2.5,5,10,12.5,15 μg dose groups. dose subcutaneous injection of 2.5 - 15 μg rE-4, the major pharmacokinetic parameters were study. A total of 46 received one dose ad- Results: After single as follows : Cmax were (119.96±25.09),(217.46 ±37.22), (388. 15±34. 16), (426.05 ±34.83), and (514.07±41.57) pg mL-1 ; Tmax were (0.81 ±0.13), (0.67±0. 13), ( 1. 13±0.44), ( 1.29 ±0.46), and( 1.08 ±0.34) h;t1/2 were (1.09±0. 15),(1.70±0.32),(1.90 ±0.64),(1.94 ±0. 15),and(1.83 ±0.36) h; AUC0-1, were (250.88±32.34),(683.85 ±137.08),(1 177.37±119.30),(1528.96±179.37),and(1739.16±137.94) h pg mL-1 ,respectively. Twelve subjects in placebo group showed adverse events, while 13 adverse events oc- curred in 11 subjects among 34 subjects receiving rE-4. Except one case of moderate hypoglycemia in 15 μg group, the rest adverse events were mild in severity. Conclusions: The data suggested an approximately dose-proportional increase in AUC0-tn values, whereas Cmax increased non-linearly over the 2.5 - 15 μg dose range. The average val- ues of other major pharmacokinetic parameters were roughly the same. The safety observations showed that rE-4 was well tolerated in the studied dose range.
