Summary

Rationale: Diabetes mellitus is a chronic disease that is often associated with long-term macrovascular and microvascular complications and decreased life expectancy. Approximately 70% of patients with type 2 diabetes mellitus (DM2) are overweight or obese. Weight loss benefits several aspects of DM2, such as improved glycemic control, increased insulin sensitivity and reduced fasting insulin. Interventions for weight loss in patients with DM2 include diet, exercise, but also pharmacotherapy and bariatric surgery. Bariatric surgery is indicated at a body mass index (BMI) \> 35 kg/m², in combination with other comorbidities. It is associated with better glycemic control and more weight reduction, compared to intensive medical treatment alone. For patients with not adequately controlled DM2 who are not eligible for surgery (i.e., BMI of \< 35 kg/m²), there is a therapeutic gap, which could be filled by one of the currently available endoscopic therapies aiming to reduce weight. One of these therapies is endoscopic sutured gastroplasty (ESG), performed with the endomina device (EndoTools Therapeutics S.A.). There is however a paucity of data showing the effect of ESG on metabolic comorbidities including DM2. We hypothesize that ESG with the endomina device will improve glycemic control in patients with DM2 and obesity. Objective: To evaluate the efficacy of ESG with the endomina device on glycemic control, in obese insulin treated type 2 diabetic patients. Study design: This is a prospective, randomized controlled trial. Study population: 58 subjects (29 in each group) with a BMI between 30 and 40 kg/m² and DM2, treated with insulin therapy. Intervention (if applicable): The intervention group will receive ESG performed with the endomina device. The control group will receive standard diabetic care. Main study parameters/endpoints: The primary endpoint is the proportion of patients with a clinically relevant reduction of insulin dose. Secondary endpoints include among others reduction in HbA1c, remission of diabetes, weight loss, quality of life and (serious) adverse events. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: An ESG with the endomina device is known to have only minor adverse events (transient abdominal cramps, nausea, vomiting), and a serious adverse event rate of \<1% (no surgical intervention needed, no mortality).

Interventions

Type	Name	Description
DEVICE	Endoscopic sutured gastroplasty with endomina	Subjects in the intervention group will be treated with an ESG with the endomina ® and TAPES devices (Endo Tools Therapeutics S.A.), both CE-marked for endoscopic gastroplasty. The endomina is a device that can be attached to an endoscope and allows remote actuation of the device during a peroral intervention. Thanks to a therapeutic channel that can be angled perpendicularly to the axis of vision of the endoscope, it allows the possibilities of making transoral full thickness tissue apposition and performing, via a transoral route, large plications with tight serosa to serosa apposition in the stomach. This suturing will be done from the incisura to the upper body of the stomach, along the great curvature with TAPES, a single use needle preloaded with suture. In addition to the endomina device, any other required endoscopic accessories can be used during the procedure (e.g., grasping forceps, loop cutter).
