The Efficacy of Canagliflozin Versus Metformin in Women With Polycystic Ovary Syndrome: A Randomized, Open Label Trial
The Efficacy of Canagliflozin Versus Metformin in Women With Polycystic Ovary Syndrome: A Randomized, Open Label Trial
Polycystic ovary syndrome (PCOS) is a common endocrine disorder, with a prevalence of 5% to 15% in premenopausal women. Patients with PCOS presents as abnormal menstruation, ovulation disorders and/or hyperandrogenemia, and often accompanied by insulin resistance and other metabolic abnormalities. Metformin has been clarified as an option in patients with PCOS. However, the clinical responses to metformin are limited and different. Sodium glucose co-transporter 2 (SGLT2) inhibitors are novel drugs for the treatment of type 2 diabetes, with weight loss, reducing insulin resistance and cardiovascular benefits. Limited data is available on the efficacy of SGLT2 inhibitors in patients with PCOS.
This clinical study aims to determine the safety and efficacy of canagliflozin vs metformin in Polycystic Ovary Syndrome (PCOS) patients with insulin resistance (IR). Methods: A single center, prospective, randomized open-label study (ratio 1:1), non-inferiority trial was conducted in the department of endocrinology, Shanghai Tenth People's Hospital between July 2019 and April 2021. PCOS women aged 18-45 years with IR were enrolled and randomly assigned to either canagliflozin 100 mg (n = 33) or metformin 1500-2000 mg (n = 35) daily for 12 weeks. The primary outcome was changes in HOMA-IR after 12 weeks treatment. The secondary outcomes included changes in anthropometric, menstrual frequency, sex hormone and metabolic parameters.
