Exclusion Criteria:

1. History of gallstones at the time of screening or previously (except for patients who had their gallbladder removed more than 3 months ago);
2. Acute pancreatitis that has clinically recovered ≤4 weeks before screening or randomization;
3. Malignant tumor within 5 years before screening or randomization (except for non-melanoma skin cancer or cervical carcinoma in situ that has been radically treated);

5. Acute coronary syndrome (such as myocardial infarction, unstable angina), history of coronary artery bypass grafting, percutaneous coronary intervention, peripheral artery revascularization, cerebrovascular diseases (such as stroke, transient ischemic attack), heart failure hospitalization, etc., within 3 months before screening or randomization;
6. Severe arrhythmias within 3 months before screening or randomization, such as recurrent symptomatic frequent ventricular premature beats, ventricular tachycardia, atrial fibrillation with rapid ventricular rate;
7. Severe infection within 3 months before screening;
8. History or presence of nephrotic syndrome, severe liver disease, Cushing's syndrome, or other diseases significantly affecting lipid levels at screening;
9. History or presence of hyperthyroidism or hypothyroidism at screening;
10. Poorly controlled hypertension at screening or before randomization (systolic blood pressure ≥180 mmHg and/or diastolic blood pressure ≥110 mmHg);
11. Diabetes with any of the following: a. Newly diagnosed within 12 weeks before screening or randomization; b. HbA1c ≥8.0% at screening; c. Type 1 diabetes;
12. Unstable or severe liver, kidney, cardiovascular, psychiatric, neurological, endocrine, hematologic, or other diseases at screening or before randomization, where the investigator determines participation poses an unacceptable risk to the subject;
13. Serious trauma or major surgery within 6 months before screening, or planning major surgery during the trial;
14. Plasma exchange therapy within 4 weeks before screening or randomization, or planned during the trial;
15. Use of other drugs significantly affecting lipid levels within 4 weeks before screening or randomization, or planned during the trial, such as traditional Chinese medicine containing statins (e.g., Zhibituo, Zhibitai), other lipid-lowering drugs and supplements (e.g., probucol, bile acid sequestrants, niacin, over-the-counter drugs, red yeast rice), GLP-1 agonists, other incretin analogues;
16. Use of weight-loss drugs or undergoing weight-altering surgery within 2 months before screening or randomization, or planned during the study;
17. History of drug abuse or alcohol abuse (including heavy drinking [average ethanol intake >80 g/day], previously diagnosed alcohol harmful use, alcohol dependence, alcohol poisoning, alcohol withdrawal, alcohol-related disorder, or alcohol-induced psychiatric or behavioral disorder);
18. Significant lifestyle changes within 4 weeks before screening or randomization, or refusal to follow lifestyle guidance or limit alcohol intake to <30 g/day during the study;
19. eGFR calculated by the Modification of Diet in Renal Disease (MDRD) formula <60 mL/min/1.73 m²;
20. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥3 times the upper limit of normal (ULN);
21. Total bilirubin or direct bilirubin ≥2 times ULN;

23. Platelet count <100 x 10⁹/L (or history of thrombocytopenia);
24. Hemoglobin <60 g/L;
25. Confirmed active syphilis, positive test result for human immunodeficiency virus antibody (HIV-Ab) or hepatitis C virus antibody (HCV-Ab), positive hepatitis B surface antigen (HBsAg) with HBV-DNA ≥1000 copies/ml (or ≥200 IU/ml, or if the detection lower limit is higher than 1000 copies/ml or 200 IU/ml, HBV-DNA ≥ detection lower limit);

27. Participation in any interventional drug clinical trial within 3 months prior to screening (participation is defined as administration of the investigational product to the subject), or still within 5 half-lives of the investigational product before screening, whichever is longer; previous participation in non-interventional clinical trials or device-related clinical trials may be judged by the investigator for inclusion;
28. Pregnant or breastfeeding women;
29. Women of childbearing potential who have not used contraception within 30 days prior to screening; women of childbearing potential and male subjects with partners of childbearing age who refuse to avoid donating sperm/eggs from the time of signing the informed consent until the end of the follow-up period, or refuse to comply with relevant contraceptive requirements;
