Liraglutide 3mg (Saxenda) on Weight, Body Composition, Hormonal and Metabolic Parameters in Obese Women With PCOS

A Randomized Placebo-controlled Double Blind Trial of Liraglutide 3 mg [Saxenda] on Weight, Body Composition, Hormonal and Metabolic Parameters in Obese Women With Polycystic Ovary Syndrome (PCOS)

There is a growing need to develop pharmacologic interventions to improve metabolic function in women with polycystic ovary syndrome (PCOS). Given that PCOS is a frequent condition and weight loss is essential but difficult to achieve, it is important to study if the effect on body weight reported in other studies can be confirmed in a selected population of hyperandrogenic patients, especially with medications currently approved for weight reduction. High dose liraglutide alone results in significant weight reduction in obese women without PCOS. There is limited data on weight loss with high dose liraglutide in non-diabetic females with PCOS treated with this agent . Studies on the effect of anti-obesity medication combined with lifestyle changes on body weight and composition and androgen excess in obese women diagnosed with PCOS are lacking. The investigators aim to elucidate the most efficacious weight reduction regime in obese PCOS women. The investigators further hope to determine which treatment(s) addressing the multifaceted disturbances of this disorder in patients with PCOS and obesity emerges as the preferable therapy.

The drug, liraglutide 3.0 mg was approved for chronic weight management in management in obese adults with an initial BMI of 30 kg/m2 or greater or in overweight adults BMI of 27 kg/m2 or greater with at least one weight-related co-morbid condition as an adjunct to a reduced-calorie diet and increased physical activity. Liraglutide is an acylated human glucagon-like peptide -1 (GLP-1) analog that binds to and activates the GLP-1 receptor. It lowers body weight through decreased caloric intake while stimulating insulin secretion and reducing glucagon via a glucose-dependent mechanism. For obesity management, patients may lose weight with GLP-1 receptor agonists due to other unique actions. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) can slow gastric emptying and increase satiety. While predictors of weight loss success for the general population are available (protein intake, weight loss medications), predictors of weight loss success may differ between normal and hyperandrogenic women. Glucagon-like peptide 1 agonists are linked with dose dependent weight lowering potential in different obesity related populations. The weight loss effects of GLP-1RAs previously demonstrated in diabetic and obese non-diabetic patients, offer a unique opportunity to expand the medical options available to patients with PCOS.

Given this lack of information, the aim of the present study was to investigate the effects of liraglutide 3mg vs. placebo on body composition as well as hormonal and metabolic features in non-diabetic obese women with PCOS.The non-diabetic obese female with PCOS offers a unique model to study the relationship between insulin resistance and adiposity. The investigators propose a double-blind, placebo-controlled 30-week trial designed to directly examine the therapeutic effects of liraglutide 3 mg (LIRA 3 mg) compared to placebo on body weight, hormonal and cardiometabolic parameters in obese non-diabetic women with PCOS. All patients will receive diet and lifestyle counseling, including advice on exercise commencing during the lead-in period and continuing throughout the study. In this study, the investigators will examine the efficacy of LIRA 3mg on body weight and body composition, reproductive function metabolic parameters and cardiovascular risk factors in a well-defined group of pre-menopausal obese non-diabetic women with hyperandrogenism, focusing on the relationship to obesity and insulin resistance.
