  • PB-201 is a novel dual-acting glucokinase activator (GKA) targeting both pancreatic and liver glucokinase. By increasing the glucokinase activity in patients with diabetes mellitus, PB-201 provides good glycemic control while reducing the risk of hypoglycemia, hence realizing blood glucose homeostasis in a safe and effective manner.

    GKA acts to improve the sensitivity of pancreatic β cells and liver to glucose, increase early phase insulin release, and facilitate GLP-1 secretion and glycogen synthesis. These features make it possible to be co-administered with a variety of hypoglycemic agents, such as metformin, DPP-4 inhibitors, and SGLT-2 inhibitors.

    PegBio has completed the phase IIa clinical trials overseas and the phase I clinical study in China for PB-201

  • PB-201是可同时作用于胰腺和肝脏葡萄糖激酶(GlucokinaseGK)的双重激活剂。葡萄糖激酶(GlucokinaseGK)主要分布于胰岛β细胞和肝细胞中,是全身葡萄糖稳态调节的控制核心。在血糖浓度升高时,胰腺和肝脏葡萄糖激酶被激活,通过促进胰岛素分泌、加强肝脏对葡萄糖的摄取、减少糖原输出等机制避免血糖水平提高。在血糖浓度降低时,葡萄糖激酶活性降低,避免低血糖的产生。

  • 1)全新机制,稳定控糖,安全耐受

    2)口服用药,提高使用便利性

    3)联合用药,覆盖不同治疗需求患者

  • PB-201已经在美国、日本及新加坡等国家完成了7项I期及2项IIa期概念验证性(POC)研究,并在中国完成了对2型糖尿病患者I期临床研究,达到了预计的安全性和初步疗效,该项研究结果以口头报告的形式在2021年美国糖尿病协会年会(ADA)公布,目前正积极向NMPA申请开展后续临床研究。
