RF Vapor Ablation Retreatment of Duodenal Mucosa in Non-responders With Type-2 Diabetes Mellitus
A Pilot Human Investigation of the Safety, Tolerability, Effectiveness of the Aqua Medical Circumferential RF Vapor (RFV) Ablation System for Duodenal Mucosal Repeat Ablation Treatment for the Management of Type-2 Diabetes Mellitus (STEAM T-2 DM Retreatment Study) in Patients Who Were Non-Responders to Initial Duodenal Mucosal Ablation Treatment

Brief Summary
The purpose of this study is to test the hypothesis that re-treatment of the duodenal mucosa with RF vapor ablation will result in improvement in glycemic parameters, without complications (bleeding/ stricture / perforation) among subjects who failed to show improvement after initial treatment of the duodenal mucosa with RF vapor ablation.

Eligibility Criteria
You may qualify if:
- Subjects previously enrolled and treated in the STEAM T2DM Clinical study.
- Subjects with improvement in HbA1c of ≤0.5% or with HbA1c of ≥ 7.5% at the 6-month visit while participating in the STEAM T2DM study.
- Agrees to use an additional glucose-lowering treatment (e.g., liraglutide, other OAD except for glyburide), if recommended by the study Investigator in case of persistent hyperglycemia.
- Able to comply with study requirements and understand and sign the Informed Consent Form
- Compliance with STEAM T2DM clinical protocol
You may not qualify if:
- Non-compliance with STEAM T2DM clinical protocol
- Diagnosis of Type-1 Diabetes
- History of diabetic ketoacidosis or hyperosmolar nonketotic coma.
- Probable insulin production failure, defined as fasting C Peptide serum \<1 ng/mL (333pmol/l).
- Previous use of any types of insulin for \>1 month (at any time, except for treatment of gestational diabetes).
- Current use of injectable medications for diabetes (insulin, GLP-1RA).
- Current use of glyburide, a sulfonylurea (SU) glucose-lowering drug for diabetes.
- History of severe hypoglycemia (more than 1 severe hypoglycemic event, as defined by need for third-party assistance, in the last year).
- Known autoimmune disease, including but not limited to celiac disease, duodenal Crohn disease or pre-existing symptoms of systemic lupus erythematosus, scleroderma or other systemic autoimmune connective tissue disorder
- History of chronic or acute pancreatitis.
- History of diabetic gastroparesis.
- Known active hepatitis or active liver disease.
- Acute gastrointestinal illness in the previous 7 days.
- Known history of severe irritable bowel syndrome, radiation enteritis or other inflammatory bowel disease, such as Crohn's disease.
- Known history of a structural or functional disorder of the esophagus that may impede passage of the device through the gastrointestinal tract or increase risk of esophageal damage during an endoscopic procedure, including moderate-severe (Grade C or D) esophagitis, dysphagia due to achalasia or stricture/stenosis, esophageal varices, esophageal perforation, or any other disorder of the esophagus.
