Effect of GLP-1 Receptor Agonism After Sleeve Gastrectomy

Overview

About this study

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.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

Age 20-65 years of age
Seen at Mayo Clinic Nutrition Clinic and have received authorization for bariatric surgery.
No active physical illness which will interfere with mobility or weight loss after bariatric surgery.
Females who are sexually active and able to become pregnant must agree to use birth control for duration of study if randomized to Saxenda/Placebo.

Exclusion Criteria:

Prior use of glucose lowering medication in the 3 months prior to screening.
A fasting glucose ≥ 126mg/dl or an HbA1c ≥ 6.5% will be taken as evidence of type 2 diabetes and therefore patients will be deemed ineligible for participation.
Prior abdominal surgery other than cholecystectomy, appendectomy or hysterectomy.
Pregnancy or active consideration of pregnancy during the period of study. Subjects will be discontinued if they become pregnant during the study.
Hypersensitivity to liraglutide or any product components.
