Clinical Trial Summary

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and one of the leading causes of infertility. PCOS and obesity affect up to 12.5% - 48.3% Asian women, increase incidence of impaired glucose tolerance, type 2 diabetes and aggravate insulin resistance, cause ovulatory dysfunction and menstrual disorders, and negatively impact outcomes of Assited Reproductive Technology (ART), with higher miscarriage rate when receiving ART. Weight loss decrease insulin resistance and hyperandrogenism, improve ovulation rate and menstrual cycle, significantly higher conception and live birth rates. Weight loss prior to IVF procedures has been associated with significantly improved pregnancy rates (PR) and live birth rates. Furthermore, a decreased number of IVF cycles required to achieve a pregnancy has also been reported after weight loss interventions. Based on the principles of fetal programming, improving a lifestyle before conception might lead to improved longterm health of the offspring. Studies on the effect of anti-obesity medication combined with lifestyle changes on body weight and composition and metabolic - endocrine parameters and pregnancy rate in obese women diagnosed with PCOS are lacking. There is a growing need to develop pharmacologic interventions to improve metabolic function in women with polycystic ovary syndrome (PCOS).

Clinical Trial Description

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. Metformin was recommended for women with PCOS and obesity (BMI ≥ 25 kg/m2) or at metabolic risks and shown beneficial effects on menstrual disorders, anovulation, hyperandrogenism, and cardiovascular abnormalities.

The aim of this study was to evaluate the impact of liraglutide in combination with metformin compared to metformin alone on weight reduction, the multifaceted metabolic - endocrine disturbances, and oocyte and embryo quality, IVF PRs and cumulative PRs (IVF and spontaneous pregnancies) in infertile obese women with PCOS who had been previously poor responders to weight reduction with lifestyle modification. ;
