STEP-1 Trial Summary

This trial will study the EndoBarrier System, a tube that goes down the throat and into the stomach, in people with type 2 diabetes and obesity who are not able to control their blood sugar levels with diet and lifestyle changes or medication. The trial will compare the EndoBarrier System plus diet and lifestyle changes to diet and lifestyle changes alone to see if the EndoBarrier System is safe and effective.

Who is the study for?
This trial is for adults aged 30-65 with type 2 diabetes for less than 15 years, HbA1c levels between 8.0% and 10%, BMI between 30 and 50, not on insulin but have been on other diabetes meds without adequate control. Women must use birth control to prevent pregnancy during the trial.Check my eligibility
What is being tested?
The EndoBarrier System's effectiveness in improving blood sugar levels in patients with poorly controlled type 2 diabetes and obesity is being tested against a sham (fake) procedure, alongside lifestyle and dietary counseling based on ADA standards.See study design
What are the potential side effects?
While specific side effects are not listed here, interventions like the EndoBarrier may cause gastrointestinal discomfort or complications, nutritional deficiencies due to malabsorption, or potential issues at the implant site.
