- 3. At screening, meet the obesity criteria defined in "WS/T586-2018 Screening for Overweight and Obesity among School-age Children and Adolescents".
- 4. Before screening, have been on dietary and exercise control alone for at least 3 months with <5.0% reduction in body mass index (based on self-report or report by parent or legally authorized representative).
- 5.Must be willing to follow the diet and exercise guidance and able to maintain such stable diet and exercise lifestyle during the study period.
- 6. Female participants of childbearing potential must have a negative serum pregnancy test at screening.
- 7. Able to understand all study procedures, willing to strictly comply with the study protocol, complete the study visits as scheduled, and finish the study.
Exclusion Criteria:
- 1. Pre-pubertal participants (Tanner Stage I).
- 2. History of severe allergic reactions or suspected allergy to study drug or its ingredients.
- 3. Pregnant or lactating women; men or women of childbearing potential planning pregnancy or unwilling to use highly effective contraception throughout the study.

- 9. History of malignancy within 5 years prior to screening, excluding clinically cured cervical intraepithelial neoplasia, squamous cell carcinoma, or basal cell carcinoma within 5 years.
- 10. Major surgery within 6 months prior to screening, or planned surgery during the study that may affect study completion or compliance;
- 11. history of bariatric surgery or planned bariatric surgery during the study (e.g., gastric bypass, gastric banding).
- 12. History of acute or chronic pancreatitis, symptomatic gallbladder disease at screening, history of pancreatic injury, or other high-risk factors for pancreatitis; or amylase or lipase >2.0×ULN at screening.
- 13. Known or suspected drug/substance abuse at screening; positive HBsAg;
- 14. Positive HCV antibody with HCV RNA above the lower limit of detection; positive HIV antibody; positive Tp-Ab.
- 15. Currently receiving or received chronic (>14 days) systemic glucocorticoid therapy within 3 months prior to screening, or evidence of severe active autoimmune disease that may require systemic glucocorticoid therapy within the next 12 months as judged by the investigator.
- 16. History of hyperthyroidism or hypothyroidism, or TSH <1.0×LLN, or TSH >1.5×ULN, or history of medullary thyroid carcinoma.
