简要总结
This study is a multicenter, randomized, double-blind, placebo-controlled, parallel phase II study to evaluate efficacy, safety, pharmacokinetics characteristics and immunogenicity of two dose levels of TG103 injection, a GLP-1 receptor agonist, in the management of overweight or obesity, to support dose selection for further development.

入选标准
- •Male or female, 18 years ≤ age ≤ 75 years.
- •Body Mass Index (BMI) ≥ 28 kg/m^2, or 24 kg/m^2 < BMI ≤ 28 kg/m^2 with at least one of obesity-related complications.
- •Regular diet and exercise and stable body weight (i.e. <5 kg self-reported change) within 12 weeks before screening as well as body weight ≥ 60 kg at screening.
- •Weight loss less than 5% or weight increase after simple diet and exercise efforts for at least 3 months.
- •Be able to understand the trial and complete the procedures, and be voluntary to participate in this study and sign the informed consent.
排除标准
- •Screening HbA1c ≥ 6.5%, or screening FPG ≥ 7.0mmol/L or<2.8mmol/L, or history of diabetes mellitus or hypoglycemia.
- •Overweight or obesity due to single gene mutation, disease or drug, or weight increase due to non-fat mass increase.
- •Treatment with any medication or product which in the investigator's opinion will cause change in weight to influence trial evaluations within 12 weeks before screening or during this study.
- •Subjects who underwent bariatric surgery within 12 months before screening, or are not yet recovered from any surgery or injury at screening.
- •Subjects who participated in any clinical trial and received the treatment within 12 weeks before screening, or who participated in the clinical trial and received treatment with TG103 injection.
- •History of allergy or suspected allergy to GLP-1 receptor agonists or antibody agents, or other severe allergy history based on which the subjects may be allergic to the study drugs in investigator's opinion.
- •Personal history or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 (MEN-2), or screening calcitonin ≥ 50 ng/L.
- •Previous history or screening ultrasound includes one of the following: chronic pancreatitis, acute pancreatitis, gallstone with at least one of less than 5mm, choledocholithiasis, except that there was no cholelithiasis after treatment or cholecystectomy.
- •No recovery from gastrointestinal disease or symptom at screening, or previous withdrawl of GLP-1 receptor agonist, GLP-1/GIP receptor agonist, GLP-1/GCG receptor agonist or metformin by gastrointestinal adverse drug reaction, or previous history of gastrointestinal surgery that influences the gastrointestinal motility in the investigators' opinions.
- •Acute infection at screening.
- •History of easily relapsed skin disease (e.g. urticaria), or present skin injury in any administration site at screening.
- •History of acute coronary syndrome, stroke, severe asthma, epilepsy, systemic lupus erythematosus, hemolytic anemia, cirrhosis and the other severe disease, or history of malignant tumor.
