Primary Outcome Measures:
  • Assessment of % Excess Weight Loss [ Time Frame: 12 months ]
    Primary efficacy was assessment of the percent excess weight loss (%EWL) at Week 52 or last assessment. Excess weight was determined from ideal body weights based on a body mass index (BMI) of 25 kg/m2. Percent excess weight loss from baseline to 12 months was calculated as [(baseline weight minus the 12-month weight) / (baseline weight minus the ideal body weight)] * 100).

Secondary Outcome Measures:
  • Improvement in Type 2 Diabetic Status [ Time Frame: 12 months ]
    Subjects who achieved HbA1c reduction of 0.5%

Enrollment: 46
Study Start Date: October 2008
Study Completion Date: July 2015
Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Device
All patients will be implanted with the Endobarrier Liner device.
Device: Endobarrier Liner
Medical device placed endoscopically in the duodenum
Other Name: GI Sleeve

Detailed Description:
Patients with obesity are at significantly greater risk of developing significant co-morbid complications, and are associated with an increased risk in all-cause mortality. The GI Endobarrier Liner represents a viable alternative to other short-term weight loss methods. It is a minimally invasive endoscopic procedure, which may allow patients to recover faster with less morbidity and mortality. This study is investigating the safety and efficacy of the GI Endobarrier Liner in patients who are candidates for bariatric surgery.
