Clinical Trial Summary

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.

Clinical Trial Description

This is a single center, double-blind, placebo-controlled, randomized, (1:1) parallel group pilot clinical trial of bicalutamide in women with either biopsy-proven or believed NAFLD receiving 6 months of bicalutamide or placebo. 50 women are targeted for enrollment. Each participant will be administered a single dose of bicalutamide or placebo once daily for a total of 6 months. In person evaluations will take place at Month 1, 2, 3, 4, 5, and 6. There will be a telephone follow up visit within 1 month of end of treatment. This is a pilot clinical trial that is largely feasibility focused. Study outcomes will include:

• Change in liver stiffness on Magnetic Resonance Elastography (MRE)

• Change in hepatic steatosis by Magnetic Resonance Proton Density Fat Fraction (PDFF)

• Change in visceral adipose tissue (VAT) volume by Magnetic Resonance Imaging (MRI)

• Change in NASH histology as assessed by the continuous NAFLD activity score (NAS), which measures different components of NASH on liver biopsy.

• Biochemical endpoints: serum lipids & HOMA-IR

• Feasibility outcomes including Rates (and reasons) for the following: a) % women that decline/women contacted for study inclusion (i.e. concern regarding randomization to placebo) b) % women enrolled/women screened (i.e. exclusion criteria too narrow), c) study dropout (i.e. medication side effects, too frequent study visits, and/or phlebotomy) ;
