This is a multi-centre, multi-national, double-blinded, placebo-controlled, parallel, randomised Phase II clinical trial to evaluate the efficacy, tolerability, and safety of a fixed dose combination of Spironolactone, Pioglitazone and Metformin (SPIOMET) for adolescent girls and young adult women (AYAs) with polycystic ovary syndrome (PCOS).~Study description: Currently, there is no European Medicines Agency (EMA)/U.S. Food and Drug Administration (FDA)-approved therapy for PCOS in AYAs. Oral contraceptives (OCs) are prescribed off-label to approximately 98% of AYAs with PCOS, including those without pregnancy risk. OCs alleviate key symptoms by inducing a pharmacological combination of anovulatory subfertility, regular pseudo-menses, and extreme elevations of sex hormone-binding globulin (SHBG), but OCs do not revert the underlying pathophysiology, and patients remain at risk for post-treatment subfertility and possibly, for lifelong co-morbidities.~Given the key role of hepato-visceral fat excess in the pathogenesis of PCOS, the prime aim of the treatment should be to achieve a preferential loss of central fat, which should in turn normalise the entire PCOS phenotype. Recent evidence disclosed that a treatment consisting of a fixed low-dose combination of two insulin sensitisers [pioglitazone (PIO) and metformin (MET), with different modes of action], and one mixed anti-androgen and anti-mineralocorticoid (spironolactone), was superior to an OC in normalising the PCOS phenotype, including ovulation rates and hepato-visceral fat.
