Effect of Heavy Alcohol Consumption on Farnesoid X Receptor (FXR) Signaling

April 3, 2023 updated by: Suthat Liangpunsakul
The main purpose of this study is to see whether heavy drinking will interfere with a specific pathway, called FXR signaling in the liver. The abnormality of this pathway may lead to liver injury in some patients who drink heavily.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Individuals ≥ 21 to 65 years old
  • Able to provide informed consent & negative urine pregnancy test where appropriate
  • Healthy controls must have not consumed any alcohol within 3 months prior to the screening visit
  • Heavy alcohol drinking is defined as > 40 grams per day on average in women and > 60 grams per day on average in men for a minimum of 6 months
  • Women of child bearing potential should be willing to practice contraception throughout the treatment period

Exclusion Criteria:

  • Active infection as evidenced by positive urine culture, blood culture, or pneumonia
  • Serum creatinine > 1.5 mg/dL
  • Known co-existing infection with hepatitis C, hepatitis B, or HIV

  • Participation in another investigational drug, biologic, or medical device trial within 30 days prior to Screening
  • Previous history of jaundice or signs of liver diseases such as spider angiomata, ascites, or history of esophageal varices or hepatic encephalopathy
  • Total bilirubin > 2 mg/dl and INR > 1.5 Page 20 of 37

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
