Study of Duodenal Mucosal RF Vapor Ablation in Subjects With Type-2 Diabetes Mellitus

Recruiting now · Not applicable

Conditions studied: Diabetes Mellitus Type 2

In brief

The purpose of this clinical study is to test the hypothesis that RF vapor ablation of the duodenal mucosa will result in improvement in glycemic parameters, without complications (bleeding/ stricture / perforation). The main aims of the study are : 1. Evaluate the safety of the device and procedure based on the reported adverse events that occur. 2. Evaluate the effectiveness of the device and procedure by comparing change in HbA1c from baseline to 168 days post procedure. 3. Evaluate device tolerability based on pain scores reported by patients. The subject population for this study are adults (18-65 years of age) with type-2 diabetes mellitus. Study participation is 6 months for each patient. The study is comprised of 5 phases: Screening, Run-in, RF Vapor ablation procedure, and Post-vapor ablation follow-up (up to 168 days), Identification and long term follow up of responders

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Men and non-pregnant women 18-65 years of age
• Diagnosed with T2D for at least 3 years and less than or equal to 10 years
• HbA1C of 7.5 - 10% (59-86 mmol/mol)
• BMI ≥ 24 and ≤ 40 kg/m2
• On a minimum of 1 stable oral anti-diabetic medications with no changes in medication in the previous 3 months prior to study entry Note: For subjects on sulfonylurea (SU) glucose-lowering drugs for diabetes, the only SUs permitted in the study will be glipizide or glimepiride, and their doses below half maximum labeled dosing will not be an exclusion for study entry. Subjects unwilling to reduce the dose of SU at the run-in period will be excluded.
• Agrees to use an additional glucose-lowering treatment (e.g., liraglutide, other OAD with the exception of 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

You may not qualify if…

• 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.
• Previous GI surgery that could limit treatment of the duodenum such as Billroth 2, Roux-en-Y gastric bypass, or other similar procedures or conditions. (Prior laparoscopic sleeve gastrectomy (LSG) will not be an exclusion)
• 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.
• Upper gastrointestinal conditions such as active ulcers, polyps, varices, strictures, congenital or acquired duodenal telangiectasia
• Current use of anticoagulation therapy (such as warfarin) that cannot be discontinued for 7 days before and 14 days after the procedure.
• Current use of P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) that cannot be discontinued for 14 days before and 14 days after the procedure.
• Unable to discontinue non-steroidal anti-inflammatory drugs (NSAIDs) during treatment through 4 weeks following the procedure. Use of acetaminophen and low dose aspirin is allowed.
• Use of systemic glucocorticoids (excluding topical or ophthalmic application or inhaled forms) for more than 10 consecutive days within 12 weeks prior to the baseline visit.
• Use of drugs known to affect GI motility (e.g. Metoclopramide)
• Use of weight loss medications such as Sibutramine (e.g. Meridia), Orlistat (e.g. Xenical), Phentermine or over-the-counter weight loss medications (prescription medication)
• Currently taking, or unable to stop taking dietary supplements or herbal agents, including vitamin C or multivitamins containing vitamin C at >500 mg per day, multivitamins containing biotin (vitamin B7), and supplements for hair, skin, and nail growth. Multivitamins not containing biotin are permitted.
• Significant cardiovascular disease, including known history of valvular disease, or myocardial infarction, heart failure, transient ischemic attack, or stroke within 6 months prior to the Screening Visit.
• Mean of 3 separate blood pressure measurements >180 mmHg (systolic) or >100 mmHg (diastolic).
