Safety and Efficacy of EndoBarrier in Subjects With Type 2 Diabetes Who Are Obese (ENDO)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT01728116
Recruitment Status : Terminated (Higher than anticipated rate of Hepatic abscess (N=7))

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.

Arm Intervention/treatment
Experimental: Device (EndoBarrier)
Device for glycemic control
Device: EndoBarrier
Endoscopically-delivered and removable device comprised of an anchor that is placed in the duodenal bulb and a 60 cm long impermeable liner that passes distal from the anchor point
Other Name: Duodenal-jejunal bypass liner (DJBL)

Sham Comparator: Sham Procedure
sham procedure
Procedure: Sham Procedure
Endoscopic evaluation but no device placement

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 ]
