The main objective of the study is to demonstrate the safety and efficacy of the Gastrointestinal (GI) EndoBarrier in the glycemic control of diabetes in subjects with Type 2 diabetes.

Condition Intervention
Type 2 Diabetes
Device: EndoBarrier Liner

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase II Single-Center, Prospective, Open Label Efficacy Study, of the GI EndoBarrier™ Liner for the Treatment of Type 2 Diabetes

Further study details as provided by GI Dynamics:

Primary Outcome Measures:
  • Assessment of Glycemic Control (HbA1c) Over Time [ Time Frame: Baseline to 12 Months with device implanted ]
    HbA1c (%) at Baseline, Month 3, Month 6, Month 9, and Month 12

  • Change in Anti-diabetes Medications [ Time Frame: Baseline to 52 weeks ]
    Medications were classified as "increased" if the dose of one or more oral agents was higher or an additional glucose-lowering agent was utilized at the time of treatment completion after EndoBarrier implantation in comparison with baseline. Medications were classified as "decreased" if the dose of one or more oral agents was lowered or one or more agents were discontinued at the time of treatment completion in comparison with baseline. For subjects in which the dose of one oral glucose-lowering agent was increased and another agent decreased, the change in medications was classified as "not assessable."

Secondary Outcome Measures:
  • Total Weight Change (kg) at Week 52 Compared to Baseline Weight [ Time Frame: Baseline to 52 weeks ]

Other Outcome Measures:
  • Fasting Plasma Glucose Over Time for All Subjects [ Time Frame: Baseline to 12 months post Device Explant ]

Enrollment: 23
