简要总结
A total of 30 subjects will be recruited 15 with intermediate hyperglycemia and 15 in the tyep 2 diabetes group respectively. Eligible participants will undergo hyperglycemic-clamp/oral glucose tolerance at baseline and after 4 weeks of dorzagliatin treatment.

研究组 & 干预措施
IH/T2D
partipiants with intermediate hyperglycemia (IH) n=15 or T2D (n=15)
干预措施: Dorzagliatin (Drug)
结局指标
主要结局
Acute Insulin secretion
时间窗: At baseline and after 4 weeks of study drug treatment
Acute (first phase) insulin response (AIRg) to glucose will be calculated as the mean incremental responses above baseline (average of -20 and -10 and 0 minutes) to the samples drawn at 2, 4, 6, 8 and 10 minutes of the hyperglycemic clamp.
次要结局
- Second phase insulin secretion(At baseline and after 4 weeks of study drug treatment)
- Beta cell glucose sensitivity(At baseline and after 4 weeks of study drug treatment)
- Glucagon-like peptide -1 (GLP-1)(At baseline and after 4 weeks of study drug treatment)
- Glucagon(At baseline and after 4 weeks of study drug treatment)
- Incretin effect(At baseline and after 4 weeks of study drug treatment)
