Eligibility Criteria

Inclusion Criteria

1. Chinese male or female adult participants aged 18-60 years (inclusive) with overweight or obesity, with no less than one-third of the participants of either gender;

2. SAD phase: Body Mass Index (BMI) = weight (kg)/height^2 , with BMI in the range of 24.0-28.0 kg/m^2 (inclusive); MAD phase: Weight ≥70 kg (for males) or ≥60 kg (for females), and BMI = weight (kg)/height^2 , with BMI ≥28.0 kg/m^2;

3. Weight change <5% in the 3 months prior to screening (can be based on self-report); calculated as: (weight 12 weeks before screening - weight at screening) / weight at screening * 100%;

4. Vital signs, physical examination, 12-lead electrocardiogram, chest X-ray (anteroposterior view), abdominal color Doppler ultrasound, clinical laboratory tests (complete blood count, urinalysis, blood biochemistry, glycated hemoglobin, coagulation function, infectious disease screening, thyroid function, calcitonin, etc.) show normal results or abnormal results deemed not clinically significant by the investigator;

5. Able to read and understand the written informed consent related to the study information, fully aware of the study content, process, and possible adverse reactions, voluntarily sign the informed consent form before the trial, and ensure that they will personally participate in any procedures; Participants and their partners agree to use effective non-hormonal contraception methods (such as condoms, inert intrauterine devices, female barrier methods [cervical cap or diaphragm with spermicide], vaginal contraceptive rings, etc.) from the time of signing the informed consent form until 6 months after the last dose, or have already adopted permanent contraception measures (such as bilateral tubal ligation, vasectomy, etc.); Male participants do not plan to donate sperm from the time of signing the informed consent form until 6 months after the last dose, and female participants do not plan to donate eggs from the time of signing the informed consent form until 6 months after the last dose.

Exclusion Criteria

1. A history of severe drug or food allergies, or any participant who is judged by the investigator to potentially be allergic to the investigational drug;

2. A history of significant diseases involving the pancreas, liver, kidneys, gastrointestinal tract, skin, cardiovascular system, respiratory system, hematological system, central nervous system, or other conditions that may endanger the safety of participants or affect the absorption, metabolism, or excretion of the study drug, and are deemed unsuitable for inclusion by the investigator;

3. A history of malignancy (except for cured basal cell carcinoma of the skin or carcinoma in situ of the cervix), psychiatric disorders (such as depression, schizophrenia, bipolar disorder, or a history of suicidal ideation or behavior), epilepsy, acute biliary disease, or confirmed acute or chronic pancreatitis; participants judged by the investigator to be unsuitable for participation in this clinical study;

4. Diagnosed with diabetes, thyroid dysfunction (abnormal TSH, FT3, or FT4 levels), Cushing's syndrome, polycystic ovary syndrome, a history of glucagonoma or pheochromocytoma, or other endocrine diseases that may affect glucose metabolism, or has experienced ≥2 episodes of severe hypoglycemia or recurrent symptomatic hypoglycemia;

5. A personal or family history of medullary thyroid carcinoma (MTC) or a history of multiple endocrine neoplasia type 2 (MEN2).

6. Any one of the following criteria is met:

i. Participants with one or more abnormal vital signs: body temperature <35.5°C or >37.2°C, pulse rate <50 beats per minute or >100 beats per minute, systolic blood pressure ≥160 mmHg or <90 mmHg, diastolic blood pressure ≥100 mmHg or <60 mmHg. A single retest is allowed, and participants with abnormalities in both tests will be excluded; ii. Any of the following laboratory abnormalities: a) Fasting plasma glucose ≥7.0 mmol/L or fasting plasma glucose <3.9 mmol/L or HbA1c level >6.5%; b) AST or ALT >2 times the upper limit of normal (ULN), total bilirubin >1.5 times ULN, deemed clinically significant by the investigator; c) Estimated glomerular filtration rate (eGFR) <90 mL/min/1.73m²; d) Serum amylase or lipase >3 times ULN; e) Blood low-density lipoprotein cholesterol (LDL-C) ≥4.40 mmol/L; f) Triglycerides (TG) ≥5.65 mmol/L.
