Bariatric Surgery Clinical Trials

Clinical trials are scientific studies of how a new medicine or treatment works in people.

Why Participate in a Clinical Trial?

The most common answer from our bariatric surgery research participants is that they want to help others who are in their situation.

Participating in bariatric surgery clinical trials will provide more, and better, information to help:

  • Patients considering bariatric surgery make their decisions.
  • Clinicians to provide the best possible care for their bariatric patients.

Triabetes Study — test to compare medical and surgical treatments for type 2 diabetes

Who can participate

Currently closed to enrollment.

Who can't participate

People who:

  • Have had prior bariatric or foregut surgery.
  • Currently smoke.
  • Cannot exercise (walk a city block or climb a flight of stairs).

What we'll study

  • The many unanswered questions about the best treatment for type 2 diabetes in patients with mild to moderate obesity.
  • Whether diabetes is influenced by the type of surgery or by the amount of weight lost, or if bariatric surgery is more effective than non-surgical weight loss induced by diet and physical activity.
  • The effectiveness of various bariatric surgery procedures versus an intensive behavioral intervention to induce weight loss with diet and increased physical activity.
  • The feasibility of performing this type of randomized trial.

How we'll conduct the study

Participants will be randomly assigned to one of three treatment arms:

  1. Gastric bypass
  2. Gastric banding
  3. Structured weight loss program
