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.

StomaphyX versus Sham — test of a device to help reduce regain weight after bariatric surgery

​Who can participate ​Currently closed to enrollment.
​Who can't participate People who have:
  • Had revisional surgery after RNYGB.
  • An anatomic condition precluding passage of the StomaphyX device.
​What we'll study
  • ​This study will help determine if an investigational device — called StomaphyX — can reduce the amount of regained weight after bariatric surgery and weight loss.
  • The StomaphyX device is a surgical tool that is inserted through the mouth and into the stomach, to make the pouch smaller and reduce the quantity of food that can be eaten at each meal.
  • The study will observe weight and health changes in participants for one year after treatment.
​How we'll conduct the study ​Participants will be randomly assigned to one of two treatment groups:
  1. StomaphyX
  2. Sham (control)

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
​Who to contact ​To learn more about this study or about participating in future clinical trials, please call 412-641-3743 or email eagletonjk@upmc.edu.

 

Safety and Effectiveness of Allergan’s BioEnterics® Intragastric Balloon (BIBTM)  System  —  test of the safety and efficacy of balloon placed into the stomach for weight loss

​Who can participate ​Currently closed to enrollment.
​What we'll study
  • ​The safety and effectiveness of the BIBTM System — a non-surgical, non-pharmaceutical, investigational device for the treatment of obesity — in comparison to a behavioral modification program in obese patients.
  • Changes in weight, BMI, obesity-related comorbidities, and quality of life will be assessed.
How we'll conduct the study​ ​Participants will be randomly assigned to one of two treatment groups:
  1. The balloon placement group
  2. The control group
All participants will receive a 52-week behavioral modification program.
