Dihydroartemisinin for the Treatment of Polycystic Ovary Syndrome: a Multi-centre Placebo-controlled Randomized Clinical Trial

Обзор

Polycystic ovarian syndrome (PCOS) is the most frequent endocrine disorder affecting women of reproductive age, with a prevalence of 10 to 13%. PCOS is characterized by irregular menstrual cylcles/ovulatory dysfunction, hyperandrogenism, and polycystic ovarian morphology. For infertile patients seeking ovulation induction, letrozole is the drug of first choice. For PCOS patients not seeking pregnancy, there exists a variety of treatments to alleviate symptoms. It has been demonstrated that artemisinin derivatives can promote energy expenditures and insulin sensitivity by activating thermogenic adipocytes, thereby protecting against diet-induced obesity and metabolic disorders in rodents. Recently, we showed in a single arm pilot study including 19 PCOS-patients, that dihydroartemisinin ameliorated hyperandrogenemia reduced antral follicle count and normalized menstrual cycles. Based on these findings, we aim to evaluate the efficacy of dihydroartemisinin in women with PCOS in a placebo controlled randomized clinical trial. The primary outcome is return of regular menstrual cycles within 6 months after start of treatment, with antral follicle count and metabolic profile being secondary outcomes. The results will potentially impact the standard of care for patients diagnosed with PCOS.

Критерии участия

Критерии включения

• Women with PCOS defined as having irregular menstrual cycles and hyperandrogenism. Irregular menstrual cycles are defined as < 21 or > 35 days or < 8 cycles per year. Hyperandrogenism refers to either hyperandrogenemia or hirsutism. Hyperandrogenemia will be defined as an elevated total testosterone >1.67 nmol/L measured by Elecsys Testosterone II (Roche Diagnostics). Hirsutism is determined by a modified Ferriman-Gallwey Score >4 at screening exam.
• Body Mass Index (BMI) between 18.5 and 28 kg/M2
• Negative pregnancy test
• No plan for pregnancy in the coming 6 months

Критерии исключения

• Patients on oral contraceptives. A two-month washout period will be required prior to screening for patients on these agents. A one-month washout will be required for patients on oral cyclic progestins. Patients on depo-progestins or hormonal implants are excluded.
• Patients with liver disease defined as ALT or AST above normal range of each participating center, or total bilirubin>30umol/L. Metabolic dysfunction-associated steatotic liver disease (MASLD) with normal ALT and AST can be included.
• Patients with anemia (Hemoglobin < 12 g/dL) or neutropenia (neutrocyte <1.8×10\^9/L).
• Patients with renal disease defined as serum creatinine> 115umol/L.
• Patients diagnosed with other endocrine diseases that are known to cause secondary polycystic ovary morphology, e.g., Cushing's syndrome, hyperprolactinemia, congenital adrenal hyperplasia (21-hydroxylase deficiency or other enzyme deficiency), hypothyroidism, etc.
• Patients diagnosed with Type 1 or Type 2 diabetes.
• Patients with known heart disease, like heart failure, atrial fibrillation, coronary heart disease, etc.
• Patients with a history of any type of cancer.
• Patients taking other medications known to affect reproductive function or metabolism. These medications include GnRH agonists and antagonists, antiandrogens, gonadotropins, GLP-1 receptor agonist, SGLT2i, metformin and thiazolidinediones. The washout period on all these medications will be two months.
• Patients who have undergone a bariatric surgery procedure within the past 12 months.
