About this study
Official title: Pilot Trial of Bicalutamide Versus Placebo in Reproductive-Aged Women With Nonalcoholic Fatty Liver Disease (NAFLD) and Polycystic Ovary Syndrome (PCOS)
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.
Read the detailed 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)
- Being tested
- Bicalutamide 50 mg, Placebo
- Medical subject headings
- Non-alcoholic Fatty Liver Disease
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Bicalutamide 50 mgDrug
Also called Casodex
Bicalutamide capsules will be prepared from U.S. Pharmacopeia grade powder at a dose of 50 mg
PlaceboDrug
Matching placebo capsules of the same color, mass, and appearance to the bicalutamide capsules will be filled using microcrystalline cellulose powder.
| Study group | Role | What they receive |
|---|---|---|
| Bicalutamide | Experimental | 50 mg capsule administered orally once daily for 6 months Receives: Drug: Bicalutamide 50 mg |
| Placebo | Placebo comparator | Matching placebo capsule administered orally once daily for 6 months Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in liver stiffness on Magnetic Resonance Elastography (MRE)
The investigators will assess for change in the MRE quantified liver stiffness in kilopascals (kPA)
Measured: Baseline and 6 months
Secondary outcomes (4)
Change in hepatic steatosis by Magnetic Resonance Proton Density Fat Fraction (PDFF)
The investigators will assess for percent change in fat fraction by MRI-PDFF
Measured: Baseline and 6 months
Change in visceral adipose tissue (VAT) volume by Magnetic Resonance Imaging (MRI)
The investigators will assess for percent change in VAT as quantified by MRI
Measured: Baseline and 6 months
Change HOMA-IR (Homeostatic model assessment (HOMA) for insulin resistance (IR))
The investigators will assess change in continuous measures of HOMA-IR as insulin resistance is known to contribute to NASH progression
Measured: Baseline and 6 months
Change in the NAFLD Activity Score (NAS) on a scale from 0 (low activity) to 8 (high activity)
The investigators will assess for change in this histologic scoring system of NASH as a continuous measure among women willing to undergo end of treatment biopsy (not required).
Measured: Baseline and 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Bicalutamide 50 mg in people with NAFLD and PCOS, run by University of California, San Francisco at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 29 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Lily Carbullido ((415)-502-3725, myliverhealth@ucsf.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in liver stiffness on Magnetic Resonance Elastography (MRE) (time frame: Baseline and 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05979389, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2026.
