Weight ≥ 70 kg (for males) or ≥ 60 kg (for females), with a body mass index (BMI) ≥ 30 kg/m² (obesity), or 27 kg/m² ≤ BMI \< 30 kg/m² (overweight) and at least one weight-related comorbidity (such as hypertension, dyslipidemia, prediabetes, obstructive sleep apnea syndrome, metabolic dysfunction-associated steatotic liver disease, weight-bearing joint pain, cardiovascular diseases, polycystic ovary syndrome, etc.); 3. Resting heart rate ≥ 55 and ≤ 90 beats per minute (based on 12-lead electrocardiogram results during screening and before randomization); 4. The subject has undertaken weight management via diet and exercise alone for at least 12 weeks prior to screening, with a weight change of \<5.0% (self-reported), and is able to continue the same diet-and-exercise-based weight management during the study period. 5. Participants must have no pregnancy plans from the time of signing informed consent until 3 months after the last dose of the investigational product, must use effective contraception to avoid pregnancy or partner pregnancy, and must have no plans to donate sperm or eggs. Exclusion Criteria: 1. It is known that the subject has an allergic constitution, or is allergic to any component of glucagon-like peptide-1 (GLP-1) receptor agonist drugs or investigational medicinal products, or has a severe allergic disease during screening, or has a history of severe drug allergy in the past; 2. Use of any anti-hyperglycemic agents, weight-affecting medications, or prescription weight-loss medications for weight control within 12 weeks prior to screening; over-the-counter weight-loss medications or appetite suppressants within 4 weeks; 3. Laboratory abnormalities: ALT or AST ≥ 3×ULN; total bilirubin ≥ 1.5×ULN; eGFR \< 60 mL/min/1.73m²; hemoglobin \< 110 g/L (males) or \< 100 g/L (females); serum calcitonin ≥ 35 ng/L; TSH \> 6.0 or \< 0.4 mIU/L; fasting triglycerides ≥ 5.64 mmol/L; serum amylase or lipase \> 2.0×ULN; 4. It is known or discovered during screening that the electrocardiogram is abnormal and there is a significant safety risk, or further diagnosis and treatment are required, including but not limited to: arrhythmias that cannot be controlled or require drug treatment such as persistent ventricular tachycardia, second or third degree atrioventricular block, QTcF \> 450 ms, long QT syndrome family history or Brugada syndrome family history, etc. 5. There is a history or evidence of any of the following diseases: secondary or drug-induced overweight or obesity; previous diagnosis of type 1 or type 2 diabetes, or at least one laboratory test indicator suggesting diabetes during screening; previous diagnosis of acute or chronic pancreatitis, or pancreatic injury; history of gallstones or cholecystitis during screening; previous diagnosis of medullary thyroid carcinoma (MTC), multiple endocrine neoplasia type 2A or 2B, or a related family history; previously undergone gastric weight loss surgery or other weight loss surgeries, or plans to undergo weight loss surgery, liposuction, abdominal lipolysis, or other surgeries that significantly affect body weight during the study period; previously had moderate or severe depression; diagnosed with a malignant tumor within the previous 5 years or evaluated as having potential malignant tumors during screening; history of any heart disease within 6 months before screening or before randomization; cerebrovascular accident within 6 months before screening or before randomization; uncontrolled hypertension during the screening period; history of hyperthyroidism or hypothyroidism, or clinically significant abnormal thyroid function test results during screening; clinically significant gastric emptying abnormalities, requires long-term use of drugs that directly affect gastrointestinal motility, or active gastrointestinal diseases during screening.
