Endovascular Denervation (EDN) for the Treatment of Type 2 Diabetes Mellitus
- Conditions
- Type 2 Diabetes Mellitus (T2DM)
- Interventions
- Device: Endovascular Denervation System (Netrod)
- Registration Number
- NCT05673668
- Lead Sponsor
- Zhongda Hospital
- Brief Summary
This is a prospective, single-center, single-arm, self-controlled study to evaluate the effects of endovascular denervation (EDN) on insulin secretory function and insulin sensitivity in the treatment of type 2 diabetes mellitus (T2DM) .
- Detailed Description
This is a prospective, single-center, single-arm, self-controlled study. Patients with diagnosed T2DM and poor glycemic control (i.e.. glycated hemoglobin A1c (HbA1c) between 7.5% and 10.5% despite one to three oral antidiabetic drugs (OAD) and/or insulin on the basis of metformin. All included subjects will accept EDN treatment and were followed up at 7, 30 days and 3, 6, 12 months. The primary objectives were evaluate the effects of EDN on insulin secretory function and insulin sensitivity in the treatment of T2DM.
