Details and patient eligibility

About

The goal of this clinical trial is to evaluate the similarities in efficacy and safety of semaglutide injection and Ozempic® in patients with type 2 diabetes who have poor glycemic control after metformin treatment.

Participants will receive either a dose of semaglutide or Ozempic® once weekly (subcutaneous injection) as add-on to metformin for 32 weeks.

Researchers will compare the outcomes of semaglutide and Ozempic® group to see if the efficacy, safety, pharmacokinetics, and immunogenicity of them are similar.

5. Glycosylated Hemoglobin(HbA1c) >7.0% and <11.0% at screening (local lab).

Exclusion criteria

1. Laboratory tests meeting any of the following criteria at screening:

   1. Calcitonin ≥50ng/L (pg/mL);

   6. Aspartate aminotransferase ≥3×ULN;
   7. Total bilirubin ≥2×ULN;
   8. Estimated glomerular filtration rate (eGFR) <60ml/min/1.73m2 (eGFR=175×Scr-1.234 (mg/dl)×age-0.179 (female×0.79), Scr unit conversion: 1mg/dl = 88.4μmol/L).

2. Positive HIV antibodies at screening.

3. Patients who have received other anti-diabetic drugs other than metformin within 60 days before screening. Such drugs include, but are not limited to, alpha-glycosidase inhibitors (such as acarbose), thiazolidinediones, glucagon-like peptide-1(GLP-1) analogs, dipeptidyl peptidase 4 (DPP-4) inhibitors, except short-term treatment with insulin (cumulative insulin treatment is allowed for ≤7 days within 60 days before screening).

4. Patients who have used GLP-1 receptor agonists within 3 months before screening, or have stopped using GLP-1 receptor agonists due to poor safety or efficacy.

5. Patients who have used weight loss drugs or have a weight change of more than 5% within 3 months before screening.

6. Continuous or cumulative use of systemic glucocorticoids for more than 7 days within 3 months before screening (systemic glucocorticoids: intravenous, oral or intra-articular glucocorticoid treatment).

7. Plan to receive glucocorticoids, immunosuppressants, or other drugs (except topical medications and inhaled preparations) that are assessed as unsuitable during the trial by the investigator.

8. Those who have participated in other clinical trials and received experimental drugs or placebo intervention within 3 months before screening (except those who only signed the ICF and did not receive any drug or placebo).

9. Those who are known to be allergic to the investigational drug or its excipients, or have a history of allergy to GLP-1 drugs, or are in an allergic state at the time of screening, or are unfit for the study due to allergy risks, per investigator's judgment.

10. Diagnosis of type 1 diabetes, diabetes caused by pancreatogenic injury or other special types of diabetes.

11. Have a history of acute diabetic complications (diabetic ketoacidosis, lactic acidosis or hyperosmolar hyperglycemic state) within 6 months before screening.

12. Recurrent (≥3 times) severe hypoglycemia or asymptomatic hypoglycemia events within 6 months before screening.

13. Patients who have hemoglobinopathies or hemolytic anemia, have received blood or plasma products within 3 months before screening, or have donated blood or lost more than 400 mL of blood within 3 months before screening.

14. History of congestive heart failure: New York Heart Association (NYHA) Class IV.

Patients who have acute coronary syndrome or cerebrovascular event (except old lacunar infarction) within 3 months before screening, including but not limited to acute myocardial infarction, unstable angina, stroke/transient cerebral ischemia attack, or have undergone heart-related surgery (including coronary artery bypass grafting, percutaneous coronary intervention) within 3 months before screening, or have poor blood pressure control at the time of screening (defined as systolic blood pressure ≥160 millimeter of mercury(mmHg) and /or diastolic blood pressure ≥100 mmHg with antihypertensive drugs) or any other cardiovascular/cerebrovascular diseases that are not suitable for participating in this trial.

16. History of proliferative retinopathy or diabetic macular edema, or any other unstable retinopathy (rapidly progressive) recorded in medical history and may require treatment during the study.

17. Patients with a history of acute/chronic pancreatitis, symptomatic gallbladder (such as multiple gallbladder stones, excluding cholecystectomy), pancreatic injury, or other conditions that may lead to high risk for pancreatitis.

18. Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN2).

20. Patients who have clinically significant gastric emptying abnormalities (such as severe diabetic gastroparesis, gastric outlet obstruction, etc.), have undergone or plan to undergo surgery that affects gastric emptying during the study period, or have long-term use of drugs that affect gastrointestinal motility.

21. Patients with history of alcohol abuse or drug addiction within 6 months before screening; or who have a mental illness (such as depression, etc.) that the may affect participation in the study, in the judgment of the Investigator.
