Background and study aims
Polycystic ovary syndrome (PCOS) is a medical condition that affects the function of a woman’s ovaries. Women with PCOS may have cysts in the ovaries, irregular ovulation and high levels of androgens (male hormones). Symptoms include irregular periods (or no periods at all), difficulties getting pregnant, excessive hair (hirsutism), commonly on the face, chest, back and buttocks, gaining weight, hair thinning and acne. It is also associated with an increased risk of type 2 diabetes and other health problems later in life, such as cardiovascular disease. There is no approved therapy. Prime recommendation is to give an oral contraceptive (OC) which treats the symptoms, but may decrease the sensitivity to insulin, worsen markers of cardiovascular health, and therefore affect the long-term health. Here, we compare the long-term effects of an OC with those of a low-dose combination of medications that improve insulin sensitivity and decrease the affects of androgen to investigate whether besides the clinical symptoms, this combination is capable of improving the risks for future complications for young women with PCOS.

Who can participate?
Girls under 16 diagnosed with PCOS with decreased sensitivity to insulin, excess androgen levels and with no/irregular periods.

What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 are given Loette Diario (OC). Those in group 2 are given SPIOMET, that is, spironolactone, pioglitazone and metformin; this combination aims to improve insulin sensitivity and reduce the effects of androgen. All participants are tested for insulinema (insulin in the blood) and their levels of visceral (abdominal) and hepatic (liver) fat.

What are the possible benefits and risks of participating?
This study compares the standard treatment with an alternative, pathophysiology-based therapy (with a low-dose combination of insulin sensitizers and anti-androgens). A preliminary study has been performed using the combinations to be used here and the results show a divergence in the outcomes, with the combination having more benefits on risk markers. The medications are safe and there is no evidence of side effects.

Where is the study run from?
Hospital Sant Joan de Déu, University of Barcelona (Spain)

Scientific titleEthinylestradiol-levonorgestrel versus spironolactone-pioglitazone-metformin (SPIOMET) for adolescent girls with hyperinsulinemic androgen excess: effects on hepatic and visceral fat and on insulin sensitivity
Study acronymOC vs SPIOMET
Study objectivesOral contraceptives (OC) and SPIOMET will improve the measures of androgen excess comparably. SPIOMET treatment will be followed by more favorable changes of the primary outcomes (visceral and hepatic fat and insulinemia), and of secondary outcomes (lipids, CRP, carotic intima-media thickness [cIMT], high-molecular-weight adiponectin, miRNAs, leukocyte telomere length, microbiome, gene expression in subcutaneous adipose tissue).
Ethics approval(s)Agencia Española del Medicamento y Productos Sanitarios, 22/01/2016
Health condition(s) or problem(s) studiedHyperinsulinemic androgen excess in adolescent girls
InterventionIn this single-centre, open-labelled, controlled trial, the randomization (1:1) will be web-based (http://www.SealedEnvelope.com), using random permuted blocks, with strata for age (<16.0 or ≥16.0 years) and BMI (<24.0 or ≥24.0 Kg/m2).

Girls will be randomly assigned to receive once daily, at dinner time, either Loette Diario (Pfizer, Madrid, Spain; 20 mcg ethinylestradiol plus 100 mg levonorgestrel for 21/28 days, and placebo for 7/28 days) or SPIOMET, a low-dose combination of separate generics: 50 mg spironolactone (one half of a 100 mg tablet of Aldactone from Pfizer, Madrid, Spain); 7.5 mg pioglitazone (one half of a 15 mg tablet of Actos from Takeda, Madrid, Spain); and 850 mg metformin (one full 850 mg tablet of Metformina from Sandoz, Barcelona, Spain).

The randomization will be performed by an investigator who will not be based in the recruiting hospital and who will be blinded to the patients’ characteristics (except for age and BMI).
