---|---|
Experimental: AGBS + Moderate Intensity Lifestyle Therapy Group
Patients randomized to treatment will receive the AGBS device
|
Device: AGBS
The AGBS is designed to promote weight loss in individuals with obesity. The AGBS includes the Allurion Balloon, which is a temporary gastric balloon that promotes weight loss in individuals with obesity. The AGBS consists of up to 2 balloons placed during a 1-year period.
Other Name: Allurion Gastric Balloon System (AGBS) |
No Intervention: Moderate Intensity Lifestyle Therapy (CONTROL) Group
Patients randomized to the control arm will receive moderate-intensity lifestyle therapy.

- Responder Rate (RR) dichotomized at 5% TBWL at 48 week [ Time Frame: 48 weeks ]Responder Rate (RR) dichotomized at 5% TBWL at 48 weeks is significantly greater than 50%
- %TBWL is significantly greater than Control Group mean %TBWL at 48 weeks [ Time Frame: 48 weeks ]%TBWL is significantly greater than Control Group mean %TBWL at 48 weeks, with a super superiority margin of 3.0%
- Responder Rate (RR) dichotomized at both 5% and 10% TBWL at both 16 and 24 weeks [ Time Frame: 48 weeks ]Responder Rate (RR) dichotomized at both 5% and 10% TBWL at both 16 and 24 weeks: RR per treatment will be assessed using an exact binomial test and compared between treatments using a two-sided Fisher Exact test; p-values will be descriptive statistics.
- RR dichotomized at 10% TBWL at both 40 and 48 weeks [ Time Frame: 48 Weeks ]Among those receiving a second balloon, RR dichotomized at 10% TBWL at both 40 and 48 weeks: RR per treatment will be assessed using an exact binomial test and compared between treatments using a two-sided Fisher Exact test; p-values will be descriptive statistics.
- Change in body fatness as measured by Body Mass Index (BMI) at 24 and 48 weeks [ Time Frame: 48 Weeks ]Change in BMI (kg/m2) will be calculated as: BMI at follow-up - Baseline BMI Change in BMI will be assessed using a paired t-test within each treatment group and compared between treatments using a two-group unpaired t-test; p-values will be descriptive statistics.
- Change in metabolic parameters [ Time Frame: 48 Weeks ]Change from screening/baseline in metabolic parameters at 48 weeks. These include HbA1c, total cholesterol, HDL-C, LDL-C, Triglycerides and LFTs. Change in metabolic parameters will be assessed using a paired t-test within each treatment group and compared between treatments using a two-group unpaired t-test; p-values will be descriptive statistics.
