Details and patient eligibility

About

This is a multi-center, open-label study to assess the feasibility and preliminary safety of the Endogenex Device for endoscopic duodenal mucosal regeneration in patients with type 2 Diabetes inadequately controlled on 2-3 non-insulin glucose-lowering medications.

Full description

Individuals who sign the informed consent will be screened for study eligibility. Eligible participants will be treated with the Endogenex procedure and followed up for 48 weeks.

Enrollment

20 estimated patients

Exclusion criteria

Diagnosed with type 1 diabetes
History of diabetic ketoacidosis or hyperosmolar nonketotic coma
Probable insulin production failure, defined as overnight 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) in last 2 years.
Current use of insulin
Hypoglycemia unawareness
History of ≥1 severe hypoglycemia episode (defined by needing for third-party assistance) in past 6 months from the screening visit
Known autoimmune disease, as evidenced by a positive anti-glutamic acid decarboxylase (GAD) test, including but not limited to celiac disease, or pre-existing symptoms of systemic lupus erythematosus, scleroderma or other autoimmune connective tissue disorder. (Participants with adequately controlled primary hypothyroidism may be included).
Previous GI surgery that has changed GI anatomy or could limit treatment of the duodenum, such as Billroth 2, Roux-en-Y gastric bypass, gastric band or other similar procedures or conditions.
Known history of a structural or functional disorder of the upper GI tract that may impede passage of the device through the upper GI tract or increase risk of tissue damage during an endoscopic procedure, including esophagitis, stricture/stenosis, varices, diverticula, or other disorder of the esophagus, stomach and duodenum.
Active H. pylori infection (Participants with active H. pylori may continue with the screening process if they are treated with an appropriate antibiotic regimen)
History of, or gastrointestinal symptoms suggestive of gastroparesis.
Acute gastrointestinal illness in the previous 7 days
Known history of irritable bowel syndrome, radiation enteritis or other inflammatory bowel disease, such as Crohn's disease and Celiac disease
History of chronic or acute pancreatitis.
Known active hepatitis or active liver disease other than NASH/NAFLD.
Alcoholic liver disease, as indicated by ANI > 0
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)

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.

Known immunocompromised status, including but not limited to individuals who have undergone organ transplantation, chemotherapy, or radiotherapy within the past 12 months, who have clinically significant leukopenia, who are positive for the human immunodeficiency virus (HIV) or whose immune status makes the participant a poor candidate for clinical trial participation in the opinion of the investigator.
