Primary Outcome Measures:
  • Percent excess weight loss (%EWL) from baseline after 12 months from randomization. [ Time Frame: Baseline, 12 months ]

Secondary Outcome Measures:
  • Percent excess weight loss (% EWL) from baseline at each study visit [ Time Frame: Baseline and each study visit ]
  • Change from baseline in levels of satiety and appetite at each study visit. [ Time Frame: Baseline and each study visit ]
  • Percentage change in body weight and BMI from baseline at each study visit [ Time Frame: Baseline and each study visit ]
  • Proportion of subjects who attain ≥ 20% EWL from baseline after 12 months from randomization [ Time Frame: Baseline and 12 months. ]
  • Proportion of subjects who lose ≥ 5% in body weight from baseline through Month 9, and maintain the weight loss for at least 3 months (i.e., through 12 months from randomization) [ Time Frame: Baseline and each study visit. ]
  • Time to loss of weight maintenance or "relapse of weight loss" [ Time Frame: Baseline and each study visit ]
  • Incidence of adverse events, Incidence of device complications, Change in blood chemistry and hematology laboratory assessments [ Time Frame: During the course of the study until termination. ]

Arms Assigned Interventions
Active Comparator: A
All subjects enrolled will be implanted with an IGS system. The active group are those randomized to "on" and will receive active stimulation for 12 months.
Device: Transcend II Model 8848
All subjects will be implanted with the IGS device and then randomized to "on" or "off" for 12 months. After 12 months all subjects will be turned "on" through 24 month follow up.
Placebo Comparator: B
All subjects enrolled will be implanted with an IGS system. The placebo group are those randomized to "off" and will receive no stimulation for 12 months.
Device: Transcend II Model 8848
All subjects will be implanted with the IGS device and then randomized to "on" or "off" for 12 months. After 12 months all subjects will be turned "on" through 24 month follow up.

Detailed Description:

The purpose of this study was to evaluate efficacy and safety of the IGS system in a population of patients with a BMI between 35 and 55 kg/m2.

SHAPE was a randomized, placebo-controlled, double-blind, multi-center pivotal study in which all subjects were implanted with the IGS system.
