Clinical Efficacy and Safety of Using 3.0mg Liraglutide to Treat Weight Regain After Roux-en-Y Gastric Bypass Surgery

Study Overview
=================
Brief Summary
-----------------
This is a randomized, double-blinded, placebo-controlled trial of liraglutide versus placebo over a follow-up period of 12 months in patients at least 18 months following Roux-en-Y gastric bypass (RYGB) who are experiencing weight regain. This study will assess the efficacy of liraglutide in improving cardiometabolic risk profile (as indicated by serum lipids, HbA1c, and waist circumference) and quality of life (as assessed by PHQ-9 (Patient Health Questionnaire), versus placebo in patients at least 18 months following RYGB who are experiencing weight regain as well as the safety of liraglutide in this patient population.

Detailed Description
-----------------
The specific aims of this study are to: To evaluate the effects of liraglutide on body weight loss in patients who are experiencing weight regain following RYGB. To evaluate the effects of liraglutide on cardiometabolic risk and quality of life in patients who are experiencing weight regain following RYGB. To evaluate the safety of liraglutide in post-RYGB subjects. To evaluate the changes in obesity-related comorbid conditions in patients who are experiencing weight regain following RYGB.
