11. Clinically significant hypoglycemia occurring during the run-in period, defined as a) 2 or more glucose alert values of ≤70 mg/dL (3.9 mmol/L) unless a clear, correctable, precipitating factor can be identified; b) clinically significant hypoglycemia with self-monitored or laboratory plasma glucose level <54 mg/dL (3.0 mmol/L); or c) severe hypoglycemic episode requiring third party assistance
12. Known intestinal autoimmune disease including celiac disease, ulcerative colitis, Crohn's disease, lupus erythematosus, scleroderma, or other autoimmune connective tissue disorder that affects the small intestine
13. Secondary hypothyroidism or inadequately controlled primary hypothyroidism (thyroid stimulating hormone [TSH] value outside the normal range at screening as determined by the central laboratory).
14. Known thyroid cancer or hyperthyroidism with treatment within the past 12 months or inadequately controlled hyperthyroidism (TSH value outside the normal range at screening as determined by the central laboratory).
15. An uncontrolled endocrine condition such as multiple endocrine neoplasia (except T2D)
16. Known structural or functional disorder of the esophagus including any swallowing disorder, esophageal chest pain disorders, drug-refractory esophageal reflux symptoms, or active and uncontrolled gastroesophageal reflux disease (GERD) (defined as Los Angeles Grade C or D esophagitis)
17. Known structural or functional disorder of the stomach including active gastric ulcer, chronic gastritis, gastric varices, hiatal hernia (a large hiatal hernia or type II and higher paraoesophageal hernia), cancer, or any other disorder of the stomach
18. Previous GI surgery that could affect the ability to treat the duodenum such as subjects who have had a Billroth 2, Roux-en-Y gastric bypass, gastric sleeve, or other similar procedures or conditions
19. Known history of chronic pancreatitis or a recent history of acute pancreatitis within the past year
20. Presence of acute or chronic active hepatitis B or C (except if hepatitis C is cured) or cirrhosis, hepatic decompensation/acute liver disease during the last 6 months, or alcoholic or autoimmune chronic hepatitis
21. Symptomatic gallstones, symptomatic kidney stones, or acute cholecystitis
22. Clinically active systemic infection
23. Known immunocompromised status including but not limited to individuals who have undergone organ transplantation, chemotherapy, or radiotherapy within the past 12 months; have clinically significant leukopenia; are positive for the human immunodeficiency virus (HIV); are on potential immunosuppressants; or individuals whose immune status makes the subject a poor candidate for clinical trial participation in the opinion of the investigator
24. Known active malignancy or partial remission from clinically significant malignancy within the past 5 years (except basal or squamous cell skin cancer, carcinoma in situ, those who received curative treatment and are in complete remission for 5 years, or if the subject is confirmed as cancer free)
25. Known active coagulopathy or current upper gastro-intestinal bleeding conditions such as ulcers, gastric varices, strictures, or congenital or acquired intestinal telangiectasia
26. Known cases of sickle cell anemia, thalassemia, or conditions that affect red blood cell (RBC) turnover such as a recent blood transfusion within 90 days. Current persistent anemia, defined as hemoglobin <10g/dL
27. Use of anticoagulation therapy (e.g., warfarin, coumadin, or novel oral anticoagulants [NOACs]) or anti-platelet agents (e.g., thienopyridine) which cannot be discontinued for 5-7 days or 2 drug half-lives before the procedure
