Brief Summary

This is a prospective, multicenter, single group feasibility clinical trial to evaluate the safety and efficacy of Endovascular denervation for the treatment of type 2 diabetes mellitus (T2DM) using the Endovascular denervation system (Generator and Catheter).

Detailed Description

This is a prospective, multicenter, single group feasibility clinical trial. Patients with T2DM with poor glycemic control, glycated hemoglobin A1c (Hba1c) between 7.5% and 10.5% treatment with at least one to three oral antidiabetic drugs and/or insulin on the basis of metformin. All eligible patients will accept EDN treatment and were evaluated at 7, 30, 60, 90, 180, 365, 730 days post procedure. The primary safety endpoint is the number of composite major adverse events (MAE) * related to the study device and/or the denervation procedure during procedure and within 30 days after the procedure, the primary efficacy is Hba1c changes from baseline to 6 months post procedure.

Eligibility Criteria

Inclusion Criteria

1. Subject with age of >18 years old and<65 years old (both ends included)

3. Diagnosed with T2DM for 1-15 years (according to WHO criteria)

4. Metformin (daily dose ≥1000mg) was combined with 1-3 Oads for more than 3 months and/or insulin (no dose limit). Specific Oads were: insulin secretagogues (sulfonylureas/glinides), thiazolidinediones (TZDS) and α-glucosidase inhibitors (see Note), and the combined Oads were at least half of the maximum approved dose in the package insert

5. The above OAD treatment is not effective for more than 3 months, and the glycosylated hemoglobin (HbA1c) level is between 7.5% and 10.5% (based on baseline examination)

6. Body mass index (BMI) between 18 and 40kg/m2 (both ends included)

Exclusion Criteria

1. Type 1 diabetes or late-onset autoimmune diabetes in adults (LADA), or any secondary diabetes

2. Previous aortic disease (e.g., aortic aneurysm or dissection) or aortic surgery (including celiac artery denervation)

3. Baseline CTA showed aortic aneurysm or dissection, or anatomical abnormalities of the hepatic artery and its branches, or other abnormal vascular structure/status (e.g., severe tortuosity or stenosis of the artery, intraval thrombus, or unstable plaque) deemed by the investigator to be unsuitable for vascular ablation.

4. More than 2 self-reported or documented episodes of severe hypoglycemia in the past 6 months (defined as hypoglycemia with severe cognitive impairment requiring assistance from another person)

5. Have had more than one documented episode of hyperglycemia requiring hospitalization in the past 6 months, including diabetic ketoacidosis, hyperosmolar coma, etc

6. Severe diabetic complications, such as retinal, renal, vascular, neuropathy, and diabetic foot, were considered by the investigator to be ineligible for enrollment in this trial

7. Major cardiovascular and cerebrovascular events (MACCE) within the past 6 months, including cerebrovascular accident (CVA), transient cerebral ischemia (TIA), heart failure (NYHA class III-IV), acute myocardial infarction, or unstable angina requiring hospitalization (including previous coronary artery bypass grafting or coronary stent implantation); And uncontrolled or severe arrhythmias

8. Severe autonomic neuropathy (orthostatic hypotension, gastroparesis syndrome, etc.)

9. Untreated or uncontrolled high blood pressure (SBP≥160mmHg or DBP≥100mmHg), or low blood pressure (BP < 90/50 MMHG)

10. A history of renal insufficiency or failure with a baseline estimated glomerular filtration rate (eGFR) < 60mL/min/1.73m2 (see Note c of the Clinical Data collection Table in Table 5-2 for the eGFR formula)

11. Chronic active hepatitis, severe hepatobiliary disease (including cirrhosis), or hepatic insufficiency (alanine and/or aspartate aminotransferase > 3 times the upper limit of normal or serum total bilirubin > 2 times the upper limit of normal)

12. Acute and chronic pancreatitis during screening and baseline periods

13. Acute systemic infections during the screening and baseline periods

14. Bleeding tendency or coagulopathy (PT, APTT, or INR > 2 times the upper limit of normal; Platelet count < 80×109/L or ≥ 700×109/L)

15. Active GI ulcer or GI bleeding within 3 months before baseline

16. Symptomatic cholelithiasis (including cholecystolithiasis, extrahepatic bile duct stones, and intrahepatic bile duct stones) but without effective treatment such as cholecystectomy, choledocholithotomy, internal drainage or external drainage

17. Hyperthyroidism, hypothyroidism, acromegaly, Cushing's syndrome and other endocrine and metabolic diseases

18. Autoimmune diseases

19. Diagnosed with a high risk of malignancy or cancer development/recurrence, or expected life expectancy < 12 months

20. History of major surgical procedures within the past 3 months

21. A condition or concomitant medical condition, such as hemoglobinopathy or hemolytic anemia, that could have prevented the primary end point from being assessed

25. Use of weight-loss medications such as orlistat or other possible treatments for weight loss (weight-loss tea/herbal medicine/acupuncture, etc.) within 3 months before the screening period

26. Prior or anticipated bariatric surgery such as subtotal gastrectomy/liposuction

27. Receipt of central sympathetic inhibitors or anticonvulsants within 3 months prior to or anticipated during the screening period

33. Expect to participate in a clinical trial of another drug or medical device within 24 months after baseline surgery

34. Pregnant or lactating women, or those planning to become pregnant within the next 2 years (all women of childbearing age must undergo a pregnancy test within 7 days before baseline surgery)

35. Drastic changes in diet and exercise habits are expected during the study (due to religious/work needs/weight loss, etc.)

37. History of alcohol/drug/substance abuse

38. Scheduled periodic blood product therapy or severe blood loss during the previous 3 months/study period

39. According to the investigator's judgment, there is any situation that affects the safety of the subjects or interferes with the evaluation of the test results

40. Subjects had aortic aneurysm or aortic dissection confirmed on angiography before EDN

41. The subject's vascular structure and conditions were considered by the investigator to be unsuitable for ablation (e.g., severe tortuosity or stenosis of the artery, abnormal vascular anatomy, intracavinal thrombus, or unstable plaque).
