Inclusion criteria

•Overweight/obese Chinese subjects, who voluntarily sign the Informed Consent Form (ICF), can receive subcutaneous injection, fully understand the content, process and possible adverse reactions of the trial, and are able to follow the regulations on contraindications and restrictions specified in this protocol.
•Male or female, 18 to 50 years of age at signing the ICF (both inclusive).
•Weight ≥ 50 kg and body mass index (BMI) within 24-33 kg/m2 (both ends inclusive) at screening.
•Subjects of childbearing potential with no birth plan from the signing of ICF to 3 months after the last dose, willingness to take effective contraceptive measures, and no plan for sperm or ovum donation. Females of childbearing potential must not be lactating and must have negative results of pregnancy tests at screening and Visit 2 (prior to enrollment).

Exclusion criteria

•Subjects with a previous or existing history of heart, liver, kidney, gastrointestinal tract, respiratory system, nervous system, psychiatric disease, malignant tumor and other diseases that are judged by the investigator to have an impact on pharmacokinetics and safety evaluation.
•History or existing diseases that increase the risk of subjects, such as hypoglycaemia, acute or chronic pancreatitis, pancreatic injury, history of symptomatic gallbladder disease; cholelithiasis with high risk of acute biliary pancreatitis at screening (e.g., silt-like lithiasis, gallbladder ≤ 5 mm in diameter and bile duct stone, etc.).
•Subjects with previous or existing diseases that significantly affect drug absorption, metabolism or excretion, such as history of active peptic ulcer or haemorrhage, inflammatory bowel disease, abnormal gastric emptying (such as gastric paresis or pyloric stenosis, gastric outlet obstruction), long-term use (continuous for ≥ 1 week) of drugs that affect gastrointestinal motility (including but not limited to domperidone, mosapride, macrolides).
•Subjects with severe infection or unexplained infection within 4 weeks before screening.
•Major surgery within 6 months prior to screening, or scheduled surgery or hospitalization during the study.
•History of drug abuse prior to screening; or positive results for drug abuse at screening.
•Subjects who used nicotine-containing products within 3 months prior to screening or are screened positive for nicotine in urine.
•Other factors that make subjects unqualified to participate in this trial as judged by the Investigator.
