Conditions

Type 2 Diabetes, Obesity

Brief summary

Study will monitor changes in HbA1c for subjects in Intervention arm vs control arm.

Detailed description

Randomized, Single-Center, Parallel-group, Open-label Pilot Study to Evaluate the Safety and Effectiveness of the GI Windows Magnet Anastomosis System (MAS) When Used to Create a Dual-path Enteral Diversion Compared with Medical Therapy Alone To Effect Glycemic Control in Obese Patients with Type 2 Diabetes Mellitus (T2DM)

Interventions

DEVICEMagnet Anastomosis System

The MAS will be placed using an endoscope in the duodenum and and laparoscopically into ileum. A compression anastomosis will be created in each of the patients and the diversion of enteral flow from the duodenum to ileum treats Type 2 diabetes.

The best medical management for the patients in this arm will be decided by the endocrinologist based on protocol parameters.

On 1 or more oral diabetes medications (with one at the minimum recommended therapeutic dose) 3. Hemoglobin A1C (HbA1c) between and including 6.5 and 10.0% (58 mmol/mol to 86 mmol/mol) at time of enrollment and has had a stable HbA1c over a 3-month period (i.e., \<0.3% reduction) 4.
