Overview

The objective of this study is to evaluate feasibility, safety, and efficacy of endoscopic DMR Treatment Paradigm 1 (compared to sham) and to evaluate feasibility, safety, and efficacy of re-treatment with DMR at 24 weeks (compared to baseline and a single DMR procedure) in patients with type 2 diabetes with non-insulin glucose lowering medications.

   6. Indication of acute liver disease, defined by serum levels of either ALT (SGPT), AST (SGOT), or alkaline phosphatase above 3 x upper limit of normal (ULN).
   7. Presence of acute or chronic active hepatitis B or C (except if hepatitis C is cured) or cirrhosis; or hepatic decompensation during the last 6 months; or alcoholic or autoimmune chronic hepatitis.
   8. Impaired renal function, defined as estimated Glomerular Filtration rate (eGFR) < 45 ml/min/1.73m2 or end stage renal failure or on dialysis.
   9. Diagnosed with esophageal motility disorder or Glomerular Filtration rate (GERD) gr 3 or diagnosed during screening endoscopy.

   12. Known intestinal autoimmune disease, including Celiac disease, or pre-existing symptoms of lupus erythematosus, scleroderma, or other autoimmune connective tissue disorder, which affects the small intestine. 15. Patients with active helicobacter pylori infection. Patients may be enrolled if they had history of h-pylori infection and were successfully treated.
   13. History of active malignancy or partial remission from clinically significant malignancy within the past 5 years. With the exception of basal or squamous cell skin cancer or carcinoma in situ or those received curative treatment and in complete remission for 5 years or if subject confirmed as cancer free.

   22. Any other clinical or mental condition which would jeopardize subject's safety or makes subject a poor candidate for clinical trial participation.
