Dihydroartemisinin for the Treatment of Polycystic Ovary Syndrome

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

Dihydroartemisinin for the Treatment of Polycystic Ovary Syndrome (NCT06842524) is a Phase 2 interventional studying Polycystic Ovary Syndrome (PCOS), sponsored by Shanghai Zhongshan Hospital. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

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.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Polycystic Ovary Syndrome (PCOS) and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 150 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Polycystic Ovary Syndrome (PCOS) subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - 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 Who Should NOT Join This Trial: - Patients on oral contraceptives. A two-month waiting period after previous treatment 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. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.
