A Study to Evaluate the Efficacy and Safety of DA-302168S Tablets in Subjects With Type 2 Diabetes

Korábbi kezelés

• Clinically significant active infection or other diseases (including but not limited to neurological, psychiatric, cardiovascular, endocrine, digestive, respiratory, urinary, hematological, or immunological disorders, except those related to T2DM) within 6 months prior to screening that, in the investigator's judgment, may interfere with trial results or pose additional risks with study drug administration.
• History of acute pancreatitis, or prior chronic pancreatitis or pancreatic injury, or other high-risk factors for pancreatitis.
• Acute cholecystitis within 3 months prior to ICF signing, or presence of cholecystitis/cholangitis/bile duct stones/multiple gallstones at screening, or gallbladder-related conditions at screening that, in the investigator's judgment, may predispose to cholecystitis (except those who have undergone cholecystectomy and are deemed eligible by the investigator).
• Clinically significant cardiovascular or cerebrovascular diseases, including but not limited to the following events within 6 months prior to ICF signing or during the run-in period: a. unstable angina; b. heart failure (NYHA class III or IV); c. myocardial infarction; d. coronary artery bypass grafting or percutaneous coronary intervention; e. uncontrolled severe arrhythmias, such as sick sinus syndrome, second- or third-degree atrioventricular block; f. cerebrovascular accidents, such as cerebral infarction or transient ischemic attack.

Más betegség

• History of type 1 diabetes, diabetes due to pancreatic injury, or other types of diabetes (excluding gestational diabetes) other than T2DM.
• Endocrine diseases or history that may significantly affect body weight (e.g., Cushing's syndrome, obesity due to pituitary or hypothalamic disorders), or obesity due to monogenic mutations or genetic obesity syndromes.
• Evidence of significant active autoimmune abnormalities (e.g., lupus or rheumatoid arthritis) requiring systemic glucocorticoid therapy during the trial, as judged by the investigator.
• History or family history of medullary thyroid carcinoma, thyroid C-cell hyperplasia, or multiple endocrine neoplasia type 2.
• Dysphagia or history of gastrointestinal disorders affecting drug absorption, including but not limited to gastrectomy or resection of any intestinal segment, severe gastrointestinal disease, or clinically evident gastric emptying abnormalities.
• Uncontrolled or unstable hypertension at screening, defined as SBP ≥160 mmHg and/or DBP ≥100 mmHg despite regular antihypertensive treatment, or evidence of renal artery stenosis or unstable blood pressure (including orthostatic hypotension).
• History of moderate or severe depression, or PHQ-9 score ≥15 at screening (see Appendix 2), or psychiatric disorders that, in the investigator's opinion, may affect participation.
• Electrocardiogram abnormalities during screening or run-in: heart rate <50 bpm or >100 bpm; QTcF (Fridericia-corrected) >450 ms (male) or >470 ms (female).

Laborértékek

• Acute diabetic complications (e.g., diabetic ketoacidosis, lactic acidosis, or hyperosmolar nonketotic coma) within 6 months prior to ICF signing; history of grade 3 hypoglycemia within 6 months prior to ICF signing, or ≥3 episodes of hypoglycemia (blood glucose <3.9 mmol/L) from 1 month before screening to randomization.
• Hyperthyroidism (including clinical and subclinical) at screening, or hypothyroidism not controlled with stable medication dose (defined as stable dose for ≥3 months with normal thyroid function tests) based on local laboratory reference ranges.

Egyéb

• Severe chronic diabetic complications at screening (e.g., proliferative retinopathy or maculopathy, painful diabetic neuropathy, intermittent claudication, or diabetic foot).
• Hemoglobinopathies or anemia, such as hemolytic anemia or sickle cell anemia.

• Age 18 to 75 years (inclusive), both sexes.
• Diagnosed with T2DM according to the Chinese Diabetes Prevention and Treatment Guidelines (2024 Edition) for at least 3 months at screening, and meeting one of the following: (1) on stable metformin monotherapy for ≥8 weeks prior to screening, with a daily dose of ≥1500 mg/day or maximum tolerated dose ≥1000 mg/day, in addition to diet and exercise; stable treatment defined as no change in daily dose; (2) glycemic control by diet and exercise alone for ≥8 weeks prior to screening.
• HbA1c (local laboratory) ≥7.5% and ≤11.0% at screening; and HbA1c (central laboratory) ≥7.5% and ≤10.5% at randomization.
• BMI 22.5-40 kg/m² (inclusive), and stable body weight for 3 months prior to screening (weight change <5%, calculated as [max weight - min weight] / max weight × 100%).
