Impact of Liraglutide 3.0 on Body Fat Distribution

University of Texas Southwestern Medical Center235 enrolled

Overview

This study is a clinical study to investigate the efficacy of liraglutide compared to placebo in reducing visceral adiposity measured by MRI in overweight or obese subjects at high risk for cardiovascular disease after 40 weeks on-treatment.

Obesity has long been recognized as a risk factor for all-cause mortality and morbidity, including the development of cardiovascular and metabolic diseases such as coronary artery disease, hypertension, insulin resistance, diabetes, and dyslipidemia. Obesity has recently been formally defined as a chronic disease characterized by pathophysiological processes that result in increased adipose tissue mass and can result in increased morbidity and mortality. Although the health risks associated with obesity are clear, there is an emerging appreciation that obesity per se, as defined by simple anthropometric measures such as waist circumference or body mass index (BMI), is neither necessary nor sufficient to promote cardiometabolic disease and atherosclerotic cardiovascular disease (ASCVD) risk. As a result, BMI alone is an insufficient marker of risk and may not accurately identify individuals at elevated risk for ASCVD. There is a pressing need to more accurately phenotype obesity to identify individuals at elevated risk for ASCVD that may benefit from more intensive preventive and therapeutic strategies

Interventions

LiraglutideDRUG

Liraglutide is administered once daily by subcutaneous injections with the pen-injector, either in the abdomen, thigh or upper arm. Injections can be done at any time of day irrespective of meals. Subjects will be instructed to escalate the liraglutide dose to 3.0 mg/day over a 4 week period following an initial dose of 0.6 mg/day and weekly dose escalation steps of 0.6 mg/day.

PlaceboDRUG

Placebo is administered once daily by subcutaneous injections with the pen-injector, either in the abdomen, thigh or upper arm. Injections can be done at any time of day irrespective of meals. Subjects will be instructed to escalate the placebo dose to 3.0 mg/day over a 4 week period following an initial dose of 0.6 mg/day and weekly dose escalation steps of 0.6 mg/day.
