Masking: Open Label
Primary Purpose: Treatment
Official Title: Post Marketing Study in Subjects Who Have Type 2 Diabetes Using the EndoBarrier™ Gastrointestinal Liner

Further study details as provided by GI Dynamics:

Primary Outcome Measures:
  • HbA1c (%) Measured at Week 52 [ Time Frame: 12 months ]
  • Total Weight Change From Baseline to Week 52 [ Time Frame: 12 months ]
    Total weight change at 12 months (kg) compared to baseline

  • Changes in Diabetic Medications at Treatment Completion Compared to Baseline [ Time Frame: Device explant ]
    number of patients with a decrease, increase or no change in diabetic medications at time of EndoBarrier explantation (treatment completion)

Enrollment: 45
Study Start Date: October 2010
Study Completion Date: July 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Device Device: EndoBarrier Gastrointestinal Liner
EndoBarrier Gastrointestinal Liner is intended to remain in vitro for 12 months.

Detailed Description:
Patients with obesity are at significantly greater risk of developing complications such as pulmonary dysfunction, diabetes, hypertension, and other co-morbid risks. NIH panel recommendations state that even a 10% short-weight loss would greatly reduce these risks. GI Dynamics' EndoBarrier represents a viable alternative to other short-term pre-surgical weight loss methods. EndoBarrier is a device that can be implanted and removed through minimal invasive endoscopic techniques. This endoscopic procedure brings potential benefits to patients in that it is minimally invasive, efficacious, and allows patients to recover faster with less morbidity and mortality

  • Subjects taking oral Type 2 Diabetes medications and/or insulin. Metformin is allowed, but not required.
  • Subjects with a BMI > 30 and< 50
  • Subjects willing to comply with study requirements
  • Subjects who have signed an informed consent form
  • Women who are post-menopausal, surgically sterile or on contraceptives and agree to remain on contraceptives for the duration of their study participation and agree not to become pregnant during the study.

Exclusion Criteria:

  • Subjects taking DPP4 inhibitors (ie. Januvia (sitagliptin), Galvus (vildagliptin) or incretins (ie. Byetta (exenatide), Victoza (liraglutide)
  • Subjects requiring insulin >150 units per day

    • Subjects with probable insulin production failure (fasting C Peptide serum <1.0 ng/mL)

  • Subjects diagnosed with Type 1 Diabetes Mellitus or having a history of ketoacidosis
  • Subjects requiring NSAIDs (non-steroidal anti-inflammatory drugs) or prescription anticoagulation therapy during the implant period
  • Subjects with or a history of iron deficiency and/or iron deficiency anemia
  • Subjects with or a history of abnormalities of the GI tract

  • Subjects with a known infection
  • Subjects with or a history of coagulopathy, upper gastro-intestinal bleeding conditions such as esophageal or gastric varices, congenital or acquired intestinal telangiectasia
  • Subjects mentally retarded or emotionally unstable, or exhibits psychological characteristics which, in the opinion of the Investigator, makes the subject a poor candidate for device placement or clinical study participation
  • Subjects with previous GI surgery that could affect the ability to place the device or the function of the implant
  • Subjects with active H. pylori (Note: Subjects may be enrolled if they had a prior history of H. Pylori and were successfully treated. If Subjects have active H. pylori at baseline, they can receive appropriate treatment and then subsequently enroll to the study.)
  • Subject or Family history of a known diagnosis or pre-existing symptoms of systemic lupus erythematosus, scleroderma or other autoimmune connective tissue disorder
  • Subjects with active and uncontrolled GERD
  • Subjects with severe liver or kidney failure (serum creatinine >180mmol/l)
  • Subjects with poor dentition who can not adequately chew their food
