- Be of stable weight (±5%) for at least 12 weeks before screening
You may not qualify if:
- Have type 1 diabetes mellitus
- Presence of severe chronic diabetic complications at screening, including but not limited to: proliferative diabetic retinopathy, diabetic macular edema, and severe non-proliferative diabetic retinopathy requiring acute treatment;
- History of diabetic ketoacidosis or hyperosmolar hyperglycemic state within 24 weeks prior to randomization;
- Occurrence of a Grade 3 hypoglycemic event within 12 months prior to screening, or ≥3 Grade 2 hypoglycemic events (venous or capillary blood glucose \<3.0 mmol/L) within 3 months prior to screening, or presence of hypoglycemia-related symptoms ;
- History of severe trauma, severe infection, or surgery within 12 weeks prior to screening that may affect glycemic control;
- Receipt of blood transfusion within 12 weeks prior to screening, or blood donation/loss ≥400 mL within 12 weeks prior to screening, or blood donation/loss ≥200 mL within 4 weeks prior to screening, or known hemoglobinopathy (such as thalassemia, hemolytic anemia, sickle cell anemia, etc.);
- Any unstable or treatment-requiring endocrine disorders related to glycemic control other than type 2 diabetes mellitus (such as hyperthyroidism, acromegaly, Cushing's syndrome, etc.).
