2. there are high-risk factors that may lead to pancreatitis, such as a history of acute or chronic pancreatitis, a history of symptomatic gallbladder disease (excluding post cholecystectomy), and a history of pancreatic injury; 3. a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia type 2; 4. there is a clinically relevant history of gastrointestinal disorders, accompanied by persistent nausea and vomiting, including but not limited to: gastroesophageal reflux disease with gastroparesis within the 6 months prior to screening, requiring treatment, unstable (worsening) or poorly controlled (persistent nausea and vomiting); surgical history that may affect gastric emptying; 5. screening for severe hypoglycemic events or recurrent hypoglycemic events within the previous 6 months (≥ 3 hypoglycemic events within a week, or other hypoglycemic events determined by the researcher); 6. having obvious hematological disorders (such as aplastic anemia, myelodysplastic syndrome) or any disease that causes hemolysis or red blood cell instability (such as malaria); 7. there are serious chronic complications of diabetes or there is a risk of acute complications within 6 months, and the investigator believes that it is not suitable to participate in this trial; 8. any organ system malignant tumor that has been treated or not treated within 5 years, regardless of evidence of local recurrence or metastasis, except for local basal cell carcinoma of the skin; 9. suffering from cardiovascular disease, defined as: having congestive heart failure (nyha iii-iv), unstable angina, stroke, myocardial infarction, or coronary revascularization within the first 6 months of screening; plan to undergo coronary artery, carotid artery, or peripheral artery revascularization during screening; 10. systolic blood pressure ≥ 160 mmhg and/or diastolic blood pressure ≥ 100 mmhg; 11. there is a history of thyroid disease that cannot be controlled with stable drug dosage, and it has been determined by the researchers to affect the safety or efficacy of the subjects; 12. serious trauma or infection that may affect blood sugar control has occurred within one month; 5. during screening, laboratory tests showed the following situations: 1. fasting venous glucose ≥ 13.9 mmol/l; 2. serum amylase and/or serum lipase\>3 times the upper limit of normal (uln); 3. alanine aminotransferase (alt) or aspartate aminotransferase (ast)\>3 × uln; 4. moderate (3b) or severe renal failure or renal insufficiency (estimated glomerular filtration rate \[egfr\] calculated using the chronic kidney disease epidemiology collaboration \[ckd-epi\] formula\<45 ml/min/1.73 m2) or in compliance with contraindications for metformin;
