Metformin vs Metformin Combined With GLP-1RA (Glucagon-like Peptide 1 Receptor Agonist) on Overweight/Obese PCOS Patients

Summary

The purpose of this study was to determine whether metformin combined with exenatide once weekly (EQW) is more effective than metformin alone in the treatment of overweight/obese women with polycystic ovary syndrome (PCOS). Background therapies were Diane-35 or/and progesterone capsule. 80 participants were randomized to use either metformin or metformin+EQW for 12 weeks. Greater changes in body weight were anticipated in patients treated with EQW+metformin than metformin alone in those treated with metformin.
