Bicalutamide Therapy in Young Women With NAFLD and PCOS

Recruiting now · Phase 1 · Has a placebo group

Conditions studied: NAFLD, PCOS

In brief

Nonalcoholic steatohepatitis (NASH), or fat-related liver inflammation and scarring is projected to be the leading cause of cirrhosis in the United States (U.S.) within the next few years. Women are at disproportionate risk for NASH, with approximately 15 million U.S. women affected. There is an urgent need to understand risk factors for NASH and its progression in women, and sex hormones may provide a missing link. This study will study the contribution of androgens to liver injury and progression in PCOS and mechanistic role of dysregulated lipid metabolism and visceral adiposity in this process. Such findings will provide the rationale for future efficacy studies evaluating selective androgen receptor (AR) antagonism for NASH in PCOS, or alternatively, the need to directly target visceral adiposity or lipid-specific pathways as part of a precision medicine approach to halt fibrosis progression in the nearly 5 million young women with PCOS and NAFLD in the U.S., who remain at increased risk for early onset and progressive liver disease.

You may qualify if…

• Women aged 18-42 years with hyperandrogenic PCOS
• NASH identified on liver biopsy or probable NASH on transient elastography- controlled attenuation parameter (TE-CAP) with cutoffs defined as CAP score ≥270 decibel/m and TE score > 7.0 kPA or alanine aminotransferase ≥40 U/L).

You may not qualify if…
