2. Patients diagnosed with type 2 diabetes;

7. The patient is able to understand the informed consent form, voluntarily participate in the trial and sign the informed consent form.

Exclusion Criteria:

1. Patients with type 1 diabetes or other special types of diabetes;
2. Treatment with any glucose-lowering agent other than metformin hydrochloride within 8 weeks before screening or during the screening/run-in period (≤7 total days allowed in the 8 weeks before screening) or use of GLP-1 or a dual - or multi-target agent containing GLP-1 within the past 3 months;

7. A history of two or more episodes of grade 3 hypoglycemia within 6 months before screening or grade 3 hypoglycemia (grade 3: a severe hypoglycemic event that requires assistance from another person for treatment, with altered consciousness, physical appearance, but without a specific glycemic cutoff) before screening to randomization;
8. Stress conditions such as severe trauma, acute infection or major surgery under general anesthesia that may affect blood glucose levels within 1 month before screening or during screening/induction;
9. Patients with hyperthyroidism or hypothyroidism at screening (except those with stable drug dose control for more than 3 months and normal thyroid function tests) or clinically significant abnormal thyroid function test results at screening and requiring drug treatment;
10. Patients with obvious blood system diseases that may cause hemolysis or red blood cell instability and affect HbA1c detection, including but not limited to: hemolytic anemia, aplastic anemia, myelodysplastic syndrome, etc., or blood donation or blood loss ≥400 mL within 4 weeks before screening, or receiving blood transfusion;
11. Have undergone metabolic surgery prior to screening, or had used medications and/or supplements with approved weight-loss indications within 3 months;
12. Patients with severe heart disease or cardiac insufficiency. Including, but not limited to, decompensated heart failure (NYHA class Ш or Ⅳ); Uncontrolled or severe arrhythmia; Patients have a history of acute myocardial infarction, unstable angina pectoris, or coronary stent implantation, coronary artery bypass grafting, or coronary angioplasty within 6 months before screening;
13. Patients with incident cerebrovascular events (including, but not limited to, ischemic stroke, hemorrhagic stroke, and transient ischemic attack) within 6 months prior to screening;
14. Uncontrolled hypertension (defined as systolic blood pressure ≥160mmHg and/or diastolic blood pressure ≥100mmHg), or hypotension (blood pressure < 90/60mmHg at screening);
15. Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia type 2 (MEN2) at screening;
16. Patients with a history of severe chronic gastrointestinal disease, clinically significant abnormal gastric emptying (e.g., diabetic gastroparesis, pyloric stenosis, etc.), long-term use of drugs that directly reduce gastrointestinal peristalsis, or those who have undergone gastrointestinal resection;
17. Patients with a history of chronic pancreatitis or idiopathic acute pancreatitis, or with obvious signs and symptoms of pancreatitis at the time of screening, or who have undergone pancreatectomy;
18. Treatment with systemic glucocorticoids (other than inhaled or topical glucocorticoids) within 4 weeks before screening;

19. Laboratory values at screening or before randomization:

    1. fasting blood glucose ≥13.9mmol/l;
    2. ALT and/or AST > 3× upper limit of normal (ULN);
    3. serum calcitonin >ULN;
    4. estimated glomerular filtration rate (eGFR) <45 ml/min/1.73m^2 (estimated using CKD-EPI formula);

    6. fasting triglyceride (TG) ≥5.7mmol/L;
    7. serum amylase and/or lipase > 3×ULN (if lipase cannot be detected in some centers, it is acceptable to judge based on amylase only);
20. Prolonged QTc interval (QTc interval >450 msec in men and >460 msec in women) on 12-lead electrocardiogram at screening or before randomization; PR interval >220 ms; (QTc values need to be corrected by QTcF formula);
