Brief Summary:

A Randomized, Multi-Center, Pivotal Efficacy and Safety Study Evaluating the EndoBarrier System for Glycemic Improvement in Patients with Inadequately Controlled Type 2 Diabetes and Obesity, the STEP-1 Study.

A multi-center, double-blinded, randomized, sham-controlled trial to evaluate the safety and effectiveness of the EndoBarrier System plus moderate intensity lifestyle and dietary counseling compliant with 2019 ADA Standard of Care as compared to a sham control receiving moderate intensity lifestyle and dietary counseling. Both the treatment and sham group will practice medical management compliant with STEP-1 Study Guidelines. Patients will be randomized 3 (EndoBarrier):1 (Sham).

Condition or disease Intervention/treatment Phase
Diabetes type2 Obesity Device: EndoBarrier Liner Other: Sham Not Applicable

Detailed Description:

The objective of this study is to evaluate the safety and effectiveness of the EndoBarrier System when used with moderate intensity lifestyle and dietary counseling and medical management, in patients with baseline HbA1c ≥ 8.0% and ≤10%, and BMI ≥ 30 kg/m2 and ≤ 50kg/m2, whose diabetes medications consist of at least dual therapy for 3 months, excluding insulin, yet have not achieved adequate HbA1c control (<7%).

Specific objectives of this study are:

  1. To determine if the EndoBarrier System significantly improves glycemic control
  2. To determine that the EndoBarrier System can be safely used to improve glycemic control

Arm Intervention/treatment
Experimental: EndoBarrier
Patients in ARM 1, will receive an upper endoscopy and will be treated with the EndoBarrier Liner
Device: EndoBarrier Liner
The EndoBarrier System is provided as a single-use, sterile device and consists of an EndoBarrier Liner preloaded, packaged and sterilized within the EndoBarrier Delivery System. The EndoBarrier Delivery System is utilized to deliver the EndoBarrier Liner to the proximal small intestine. The EndoBarrier Liner is removed using the EndoBarrier Retrieval System. The EndoBarrier System incorporates no pharmacological, biological tissue or blood products.
Other Names:
  • EndoBarrier Sleeve
  • Duodenal-jejunal Bypass Liner (DJBL)

Sham Comparator: Sham
Patients in Arm 2 will receive an upper endoscopy, but will not be treated with the EndoBarrier Liner.
Other: Sham
Patient receives upper endoscopy but no treatment
