Inclusion Criteria: 1. Male or female subjects ≥18 years of age and ≤75 years of age at the time of signing the informed consent form. 2. Those who meet the World Health Organization（WHO）1999 diagnostic criteria for type 2 diabetes mellitus and the WHO Recommendations for the Use of Glycosylated Haemoglobin (HbA1c) for Diagnosis (2011) supplemental diagnostic criteria for a diagnosis of T2DM for ≥ 12 weeks. 3. Those who received dietary and exercise interventions for ≥8 weeks prior to screening and who had not received any antidiabetic medications in the 8 weeks prior to screening. 4. HbA1c ≥7.5% and ≤11.0% at screening (local laboratory) and HbA1c ≥7.0% and ≤10.5% before randomization (V3) (central laboratory). 5. FPG 13.9 mmol/L at screening (local laboratory) and FPG 13.9 mmol/L before randomization (V3) (central laboratory). 6. Body mass index (BMI) ≥18.5 kg/m2 and ≤35.0 kg/m2 at screening and before randomization (V3). 7. Able to understand and willing to sign a written informed consent form (ICF) and comply with the study protocol. Exclusion Criteria: 1. People diagnosed with type 1 diabetes or other types of diabetes. 2. Those who have used other hypoglycemic agents within 8 weeks prior to screening or prior to randomization (V4), or those who have used medications that may affect glucose metabolism, such as systemic glucocorticoids (except for inhalation or topical topical use), growth hormones, etc. 3. Acute complications of diabetes, such as diabetic ketoacidosis or hyperglycemic hyperosmolar state, within 6 months prior to screening or prior to randomization. 4. Severe chronic complications of diabetes mellitus (e.g., proliferative diabetic retinopathy, severe diabetic neuropathy, diabetic foot, etc.) within 6 months prior to screening, which are assessed by the investigator to be unsuitable for participation in this clinical study. 5. Persons who have had a severe trauma or serious infection within 1 month prior to screening or prior to randomization (V4) that may affect glycemic control, and persons who currently have a complicated or refractory urinary or genital tract infection. 6. Suffering from any condition at screening or prior to randomization (V4) that may cause hemolysis or red blood cell instability that would interfere with the measurement of HbA1c levels, such as hemolytic anemia. 7. Subjects who have abnormal thyroid function tests at Screening and require medication, or subjects who are being treated with thyroid-related medications whose thyroid function is still not well controlled at Screening. 8. Those with any of the following abnormalities on serologic testing at screening: 1）Positive human immunodeficiency virus antibodies or syphilis spirochete-specific antibodies; 2）Hepatitis C antibody positive; 3）Hepatitis B virus surface antigen (HBsAg) positive and hepatitis B viral load (HBV-DNA) above the lower limit of laboratory testing (HBV-DNA is added only if HBsAg is positive); 9. The subject has other conditions that, in the judgment of the investigator, make participation in this clinical study inappropriate.
