A Study of Prusogliptin Tablets Combined With Dapagliflozin Tablets and Metformin Hydrochloride Extended Release Tablets in Type 2 Diabetes

Prior treatment

• ≥2 episodes of Grade 3 hypoglycemia within 6 months prior to screening, or any Grade 3 hypoglycemia occurring from screening to randomization;
• ≥1 episode of acute diabetic complications (e.g., diabetic ketoacidosis, hyperglycemic hyperosmolar state) within 6 months prior to screening or prior to randomization;
• Severe chronic diabetic complications (e.g., proliferative diabetic retinopathy, severe diabetic neuropathy, diabetic foot) within 6 months prior to screening;
• History of acute or chronic pancreatitis at screening or prior to randomization;
• Inflammatory bowel disease, partial intestinal obstruction, or chronic intestinal diseases associated with malabsorption within 6 months prior to screening or prior to randomization;
• Previous gastrointestinal surgeries that may cause malabsorption (excluding polypectomy and appendectomy), or chronic use of medications directly affecting gastrointestinal motility at screening or prior to randomization;
• Hemorrhagic stroke or acute ischemic stroke within 6 months prior to screening or prior to randomization;
• Acute gallbladder disease within 6 months prior to screening, or active gallbladder disease requiring treatment at screening/prior to randomization;
• Malignancy (except clinically cured basal cell carcinoma or carcinoma in situ) diagnosed or treated within 5 years prior to screening or prior to randomization;
• Severe infection or trauma within 4 weeks prior to screening/prior to randomization; recurrent urinary tract infections or genital infections within 6 months prior to screening; or symptomatic urinary/genital infections at screening/prior to randomization;
• Clinically significant hematologic diseases (e.g., aplastic anemia, myelodysplastic syndrome) or conditions causing hemolysis or erythrocyte instability (e.g., malaria) at screening/prior to randomization;

Other illness

• Type 1 diabetes or other special types of diabetes;
• History of severe psychiatric disorders (e.g., depression, anxiety disorders), severe osteoporosis, or other medical conditions that may endanger participant safety as judged by the investigator;
• Other conditions deemed unsuitable for trial participation by the investigator.

Lab values

• Any cardiovascular event within 6 months prior to screening or prior to randomization, including: decompensated heart failure (NYHA Class III or IV); unstable angina, myocardial infarction, coronary artery bypass grafting, or coronary stent implantation; long QT syndrome or prolonged QTcF interval (male \>450 ms, female \>470 ms); clinically significant arrhythmia requiring treatment and deemed unsuitable for trial participation by the investigator;

Other

• Pregnant or lactating women;

• Subjects with type 2 diabetes was confirmed at least 10 weeks prior to the screening;
• Male or female, 18 years ≤ age ≤ 75 years;
• Body Mass Index (BMI) ≥ 18.5 kg/m\^2, and ≤40 kg/m\^2;
• Stable metformin therapy for at least 10 weeks prior to screening at a dose ≥ 1500 mg per day;
• The glycated hemoglobin must meet the following standards:During screening: 7.5% ≤ HbA1c ≤ 11.0% (local laboratory);Before random sampling: 7.0% ≤ HbA1c ≤ 10.5% (central laboratory);
• Be able to understand and follow the test procedures, voluntarily participate in the test and sign the ICF.
