Endoscopic sleeve plus pulsENDO in obese adults with type 2 diabetes
Official title: Integrating Duodenal Recellularization Via Electroporation Therapy and Endoscopic Sleeve Gastroplasty as a Novel Approach to Managing Diabesity (DRAGON Study)
Run by Chinese University of Hong Kong · NCT07660445 · Data updated 2026-11-12
This trial tests whether combining Endoscopic Sleeve Gastro plasty (ESG) with pulsed electrical duodenal therapy (pulsENDO) is safe and helpful for adults with obesity and type 2 diabetes.

Is this trial a fit for you?
✓Likely a good fit
Adults with BMI 27 kg/m2 or higher, known type 2 diabetes, IMS score 25–115, and HbA1c <11% (or <8% if on insulin) who have not had prior ESG, ReCET, or similar GI procedures.
✕Probably not a fit
Patients with type 1 diabetes, prior GI surgeries precluding ESG/ReCET, significant GI inflammatory disease, or coagulopathies may not benefit.

What this trial studies
This is a prospective, single-arm feasibility study enrolling adults with obesity and type 2 diabetes. Participants will undergo combined ESG and pulsENDO procedures and will be followed for 2 years to assess safety, feasibility, and potential mechanisms of action. The study aims to provide initial data on how well this combined endoscopic approach works in improving metabolic outcomes. Tests will monitor adverse events, glycemic control, and related metabolic markers. Enrollment is at Prince of Wales Hospital, The Chinese University of Hong Kong, with lead sponsor CUHK.
Why it matters
Potential benefit: If successful, the approach could offer a less invasive option to improve diabetes control in obese patients.
How similar studies have gone: Prior endoscopic metabolic procedures have shown promise in select patients, but this specific ESG plus pulsENDO combination is novel and feasibility-focused.
