Trial summary

The purpose of this research study is to determine the way (mechanisms) by which your defect in bile acid handling (metabolism) causes your liver disease or abnormality in absorption of vitamins and the effect of an investigational bile acid therapy (glycocholic acid) on your vitamin absorption and your liver disease.

About this study

Official title: Conjugated Cholic Acid for the Treatment of Inborn Errors in Bile Acid Synthesis Involving Side-Chain Conjugation

The purpose of this research study is to determine the way (mechanisms) by which your defect in bile acid handling (metabolism) causes your liver disease or abnormality in absorption of vitamins and the effect of an investigational bile acid therapy (glycocholic acid) on your vitamin absorption and your liver disease. An investigational therapy is one that not approved by the United States Food and Drug Administration (FDA) and is being provided to you under an Investigational New Drug application from the FDA.

Read the detailed description

Inborn errors of bile acid metabolism have been established as a well recognized cause of neonatal cholestasis and fat-soluble vitamin malabsorption. Although there is extensive experience with metabolic defects in the biosynthetic pathway, few patients have identified with defects in conjugation with taurine or glycine that allows bile acids to become effective detergents. This protocol is designed to study the effect of defects of conjugation of bile acids on growth and fat-soluble vitamin malabsorption. Study subjects will have liver function studies performed, serum and urinary bile acid measurements, vitamin levels, growth measurements, bile acid pool size measurements made by stable isotope dilution mass-spectrometry, and measurements of absorption of two fat-soluble vitamins, tocopherol and vitamin D. Subjects will be treated orally with conjugates of cholic acid with follow-up laboratories performed as an outpatient and then subjects will have all of the initial studies repeated during an inpatient stay 3-12 months after starting treatment. Subjects with previous liver biopsies indicating the presence of significant liver disease will have a repeat liver biopsy after 3-12 months treatment to assess the histologic response to treatment.

Receives: Drug: Glycocholic Acid

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Conjugated Cholic Acid (GCA) for the Treatment of Inborn Errors in Bile Acid Synthesis Involving Side-chain Conjugation.

    This is the number of participants with bile acid amidation defects treated with oral glycocholic acid (15 milligrams/kilograms (mg/kg) of body weight/day (bw/day))

    Measured: Up to 10 years

  2. Evaluation of Levels of Atypical Bile Acid Metabolites After GCA Treatment Compared

    Semi-quantitative descriptive evaluation of the levels of atypical bile acids in urine measured by mass spectrometry (FAB MS) based on a scale of 0 = absent or traces levels, 1 = low levels, 2 = moderate levels, 3 = high levels using the signal/noise ratio and intensity of ions. Atypical bile acids evaluated included m/z 407 (unconjugated cholic acid), m/z 471 (dihydroxy-choleanoic-sulfate) and m/z 583 (trihydroxy-choleanoic glucuronide).

    Measured: Average of 6 months, average 12 months, and average of after year 1 to 10 years

Secondary outcomes (3)
  1. Changes in Liver Function Tests of ALT From Baseline to Post-treatment

    Liver function tests Alanine Aminotransferease (ALT)

    Measured: Comparison between baseline and post-treatment (average of available timepoints after year 1 through year 10)

  2. Change in Liver Function Test: AST From Baseline to Post-treatment

    Measure of Aspartate Aminotransferase (AST)

    Measured: Comparison between baseline and post-treatment (average of available timepoints after year 1 through year 10)

  3. Change in Vitamin D, 25-OH Measure From Baseline to Post-treatment

    Measure Vitamin D levels nanograms per milliliter (ng/mL)

    Measured: Pre-treatment and post treatment (average of available timepoints after year 1 through year 10)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Glycocholic Acid in people with Bile Acid Synthesis Defect and Inborn Error of Bile Acid Metabolism, run by Children's Hospital Medical Center, Cincinnati 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 4 inclusion and 1 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: finished, as of the sponsor's last update on 8 Jun 2022. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 May 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Conjugated Cholic Acid (GCA) for the Treatment of Inborn Errors in Bile Acid Synthesis Involving Side-chain Conjugation. (time frame: Up to 10 years). The study lists 2 primary outcomes in all. 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 NCT01589523, which also lists 2 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 8 Jun 2022.
