Brief summary: This prospective, multicenter, open label, single arm study will enroll subjects presenting with obesity and inadequately controlled type II diabetes (T2DM). A dual path jejunoileal side-to-side anastomosis is endoscopically created using the Neujia device. Subjects are followed for 12 months and annually thereafter for up to 5 years to assess change in metabolic parameters, medications, weight, and adverse events.

Detailed description: For many obese diabetics, medical treatment and lifestyle modification fail to provide acceptable glucose levels or durable weight loss. Bariatric surgical procedures have been proven to provide better glycemic control and to improve life expectancy and quality of life. But these are invasive procedures with significant complications, and notwithstanding the strong clinical evidence and consensus guidance, less than 2% of patients who would benefit from bariatric surgery choose to undergo the invasive procedures. There is therefore a significant unmet clinical need for metabolic/bariatric therapies that result in durable improvement in glycemic control, decreased anti-diabetic medication requirements, and weight loss, with fewer and less severe complications than invasive bariatric surgery.

Human clinical data suggests that partial diversion through a side-to-side jejunoileal anastomosis results in an absolute decrease in HbA1c of 1.9 to 3.6 percentage points and a decrease in total weight of 9.6 to 14.6% at 12 months. Although these studies used other methods, they provide good evidence that the anastomosis created by Neujia should be expected to safely improve glycemic control.

A minimally invasive anastomosis device (Neujia) and endoscopic delivery system have been developed to create a side-to-side jejunoileal anastomosis. One device is deployed in the jejunum, approximately 30 to 100 cm distal to the ligament of Treitz, and the other in the ileum, approximately 30 to 100 cm proximal to the ileocecal valve. The devices are mated under endoscopic guidance with fluoroscopic visualization and create a compression anastomosis. Neujia has the potential to provide a fully endoscopic, incisionless procedure that achieves durable weight loss and glycemic control without the risks of bariatric surgery. The proposed single arm study is designed to assess the feasibility and safety and efficacy of the Neujia device when used to treat T2DM and obesity. Subjects are followed for 12 months and annually thereafter for up to 5 years to assess change in metabolic parameters, medications, weight, and adverse events.
