Description as written by the study sponsor.
Observational studies suggest that bariatric surgery is the most effective intervention for weight loss. Comparative effectiveness of Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) demonstrate that RYGB is significantly superior to SG in terms of weight loss and glycemic control. Both RYGB and SG increase GLP-1 concentrations which directly affect B-cell function. Data has shown that the postprandial rise in GLP-1 might affect feeding behavior after RYGB and to a lesser extent SG, where the increase in GLP-1 is less marked. In this study the investigators propose to randomize subjects undergoing SG to receive either placebo or Liraglutide, a GLP-1 receptor agonist, to compare weight loss and CV risk factors.
Treatments tested
- Saxenda also known as Liraglutide Drug
Saxenda is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated as an adjunct to a reduced calorie diet and increased physical activity for chronic weight management in adult patients. Subjects will be recruited and screened prior to undergoing bariatric surgery. Subjects undergoing SG will be randomized 1:1 at month 3 post surgery to Saxenda, 0.6mg SQ daily, with weekly titration of 0.6mg until maintenance dose of 3mg/daily reached. Subjects will remain on study drug for duration of study (33 months). After undergoing surgery, study visits will be timed to coincide with the standard clinical follow-up visits at months 3, 6, 9, 12, 18, 24, 30 and 36.
- Placebos also known as Placebo for Saxenda (Liraglutide) Drug
Subjects will be recruited and screened prior to undergoing bariatric surgery.Subjects undergoing SG will be randomized 1:1 at months 3 post surgery to Placebo, 0.6mg SQ daily, with weekly titration of 0.6mg until maintenance dose of 3mg/daily reached. Subjects will remain on study drug for duration of study (33 months). After undergoing surgery, study visits will be timed to coincide with the standard clinical follow-up visits at months 3, 6, 9, 12, 18, 24, 30 and 36.
- RYGB Procedure
Subjects will be recruited and screened prior to undergoing bariatric surgery. After undergoing surgery, study visits will be timed to coincide with the standard clinical follow-up visits at months 3, 6, 9, 12, 18, 24, 30 and 36.
