Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 18-42 with hyperandrogenic PCOS and either biopsy-proven or probable NAFLD.

Probably not a fit

Patients with uncontrolled diabetes, other chronic liver diseases, or those who are pregnant or perimenopausal may not benefit from this study.

What this trial studies

This pilot clinical trial investigates the effects of bicalutamide, an androgen receptor antagonist, on young women aged 18-42 with nonalcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS). The study aims to understand the role of androgens in liver injury and the progression of NAFLD in this population. Participants will receive either bicalutamide or a placebo for six months, with evaluations conducted at regular intervals to assess changes in liver stiffness, hepatic fat content, visceral fat volume, and other biochemical markers. The trial will also evaluate feasibility metrics related to participant enrollment and retention.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for young women suffering from NAFLD and PCOS, potentially halting disease progression.

How similar studies have gone: While this approach is novel in targeting androgen receptors for NAFLD in women with PCOS, similar studies have shown promise in related areas of research.
