Brief Summary:
This is a phase I placebo-controlled study to assess safety, tolerability, pharmacokinetics and pharmacodynamics of Globalagliatin Hydrochloride (SY-004) after Multiple Ascending Doses in patients with Type 2 Diabetes Mellitus (T2DM).

Condition or disease Intervention/treatment Phase
Hyperglycaemia (Diabetic) Type 2 Diabetes Mellitus Drug: Globalagliatin Hydrochloride Drug: Placebo Phase 1

Detailed Description:
Glucokinase is a characteristic hexokinase isoenzyme in hepatocytes that catalyzes the first step in glucose metabolism. In addition to its role in glucose metabolism, glucokinase is expressed in pancreatic islet beta cells where it acts as a "glucose sensor" for insulin release. Activation of glucokinase increases the glucose sensitivity of insulin secretion, effectively lowering the glucose threshold for insulin secretion. Because of its potential to enhance insulin secretion and affect hepatic glucose metabolism, is being investigated for use as a treatment for hyperglycaemia, Globalagliatin( the active ingredient in SY-004 capsule) is being investigated for use as a treatment for T2DM patients. This is a phase I placebo-controlled study to assess safety, tolerability, pharmacokinetics and pharmacodynamics of Globalagliatin Hydrochloride (SY-004) after Multiple Ascending Doses in patients with Type 2 Diabetes Mellitus.
