• Body mass index (BMI) ≥ 19.0 kg/m2 and ≤ 40 kg/m2;
• Able and willing to adhere to the protocol including performing self-monitoring of plasma glucose profiles, keeping a trial diary and using a pre-filled pen device.

Exclusion Criteria:

Subjects who meet any of the following criteria will be excluded from the study:

• Subjects with diabetes of other types than T2DM;
• Known or suspected hypersensitivity to trial product(s) or related components;
• Participated in any clinical trial and Receipt of any treatment of investigational medicinal product (IMP) or medical device within 90 days prior screening;
• Treatment with glucose lowering agent(s) other than stated in the inclusion criteria 5 for cumulatively more than 14 days in a period of 90 days before screening; or treatment with these agent(s) in a period of 30 days before screening and might influence the assessment of efficacy of glycemic control (Judged by the investigator);
• Treatment with systemic corticosteroid for cumulatively more than 14 days in a period of 90 days before screening (including intravenous, muscle and subcutaneous injections, and oral administration, except for local, intraocular, nasal, intraarticular, and inhalation medications); or treatment with these agent(s) in a period of 30 days before screening and might influence the assessment of efficacy (Judged by the investigator);
• Treatment with glucose lowering agent(s) of herbal traditional Chinese medicine or other local herbal medicines for cumulatively more than 14 days in a period of 90 days before screening; or treatment with these agent(s) in a period of 30 days before screening and might influence the assessment of efficacy (Judged by the investigator);
• Treated with stable insulin regimen (except for short-term treatment (e.g., no more than 14 days of continuous treatment)), or treatment with insulin in a period of 30 days before screening and might influence the assessment of efficacy (Judged by the investigator);
• Treatment with GLP-1 receptor agonists or DPP-4 inhibitors within 90 calendar days prior to screening;
• Impaired liver function, defined as aspart aminotransferase (AST) or alanine aminotransferase (ALT) ≥ 2.5 times upper limit of the normal or a total bilirubin level (TBIL) ≥ 1.5 times upper limit of the normal;
• Triglycerides >5.6 mmol/L at screening;
• Impaired renal function, defined as creatinine clearance (Ccr) of less than 60 mL/min (calculated from the Cockcroft-Gault formula);
• Have had 1 or more episodes of severe hypoglycemia within the 6 months prior to screening.
• Have had 1 or more episodes of acute diabetic complications (diabetic ketoacidosis, hyperglycemic hyperosmolar state, diabetic lactic acidosis, etc.) within the 6 months prior to screening.
• With concomitant conditions at screening that may affect the evaluation of the study, including cardiovascular and cerebrovascular diseases, respiratory diseases, gastrointestinal diseases, liver diseases, kidney diseases, nervous system diseases, psychiatric diseases, hematological diseases, immune system diseases, endocrine system diseases, pancreatic diseases, and/or malignant tumors.
