Brief Summary:
To determine if the EndoBarrier safely and effectively improves glycemic control in obese subjects with type 2 diabetes

Condition or disease Intervention/treatment Phase
Type 2 Diabetes Obesity Device: EndoBarrier Procedure: Sham Procedure Not Applicable

Detailed Description:
This is a randomized, double blinded, prospective study. Subjects will be evaluated and randomized to either the device or sham treatment group if they qualify for the study. A comparison of glycemic control between the two groups will be assessed as the primary outcome measurement as well as the safety profile of the device.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Primary Efficacy Endpoint: Improvement in HbA1c [ Time Frame: Baseline and12 months ]
    Mean Change in HbA1c from Baseline to 12 Months in the mITT population with Bayesian Imputation

  2. Primary Safety Endpoint: Early Device Removal Due to Device-Related SAE [ Time Frame: Baseline and 12 Months ]
    Of the 161 subjects for whom data were available at 12 Months, 19 (11.8%) subjects experienced device-related SAEs that required an early device removal.


Secondary Outcome Measures :
  1. Assessment of Total Cholesterol Change at 12 Months Compared to Baseline [ Time Frame: Baseline and 12 Months ]
  2. Percentage of Subjects Who Achieve HbA1c Less Than or Equal to 7.0% at 12 Months [ Time Frame: Baseline and 12 Months ]
  3. LDL Change From Baseline [ Time Frame: Baseline and 12 Months ]
  4. Triglycerides Change From Baseline [ Time Frame: Baseline and 12 Months ]
  5. Fasting Glucose Change From Baseline [ Time Frame: Baseline and 12 Months ]
  6. Systolic BP Change From Baseline [ Time Frame: Baseline and 12 Months ]
  7. Diastolic BP Change From Baseline [ Time Frame: Baseline and 12 Months ]
  8. Percentage of Subjects Who Achieve % Total Body Weight Loss Greater Than or Equal to 5% at 12 Months [ Time Frame: Baseline and 12 Months ]
