  Purpose

The study evaluated the safety and efficacy of the ReShape Intragastric Balloon as an adjunct to diet and exercise in obese patients compared with diet and exercise alone. The study device is designed to occupy space within the stomach and induce satiety. After approval from the institutional review board, patients provided written consent and were randomized to the treatment group (with endoscopic placement of study device) or the control group (no placement of study device) on an unblinded basis. Both groups received similar diet and exercise counseling. After 24 weeks, the device was removed. Patient weight, adverse events, and quality of life data were evaluated throughout the 48 week study duration.

  4. Subject is willing to commit to a long-term low calorie (1000-1500 calories/day) supervised diet;
  5. Subject has reasonable weight loss expectations (accept a goal of losing up to 15% of body weight after 24 weeks);
  6. At screening, total Beck Depression Inventory (BDI) score < 12 points, and BDI affective subscale score < 7 points.

  9. Subject is able to provide written informed consent;
  10. If female of child-bearing potential, the subject is willing to use contraception (e.g., birth control pills, condoms, abstinence) and avoid pregnancy during the study.
