Trial summary

The purpose of this research study is to determine whether a low dose of ATRA will improve laboratory tests of liver and bile duct inflammation in patients with PSC. The investigators will also look for changes to other blood tests which are related to inflammation, scarring, and the immune system. Read more about this study

What is being measured

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

  1. Change of Serum Alkaline Phosphatase (ALP)

    Blood will be drawn at each time point to compare pre- and post-treatment values for each individual.

    Measured: Baseline to week 24.

Secondary outcomes (6)
  1. Change in Patients Who Have Normalization of Serum ALP or Reduction to Less Than 1.5 x Upper Limit of Normal (ULN)

    Blood is drawn at each time point to assess the outcome.

    Measured: Baseline to week 24.

  2. The Percent of Patients Who Have Reduction of Serum C4 by 50%

    Blood is drawn at each time point to assess the outcome.

    Measured: Baseline to week 24.

  3. The Percent of Patients Who Have Reduction of Serum Bile Acids by 50%

    Blood is drawn at each time point to assess the outcome.

    Measured: Baseline to week 24.

  4. The Percent of Patients Who Have Reduction of Serum Alanine Aminotransferase (ALT) by 50%

    Blood is drawn at each time point to assess the outcome.

    Measured: Baseline to week 24.

  5. The Percent of Patients Who Have Reduction of Serum Enhanced Liver Fibrosis Score (ELF) by 10%

    Blood is drawn at each time point to assess the outcome.

    Measured: Baseline to week 24.

  6. The Percent of Patients Who Have Improvement in Fibrosis Per Transient Elastography by at Least 1 Stage

    Transient Elastography will be performed at baseline and week 24 to assess the outcome.

    Measured: Baseline to week 24.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing All-trans retinoic acid in people with Cholangitis, Sclerosing, run by Yale University 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 5 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: stopped early, as of the sponsor's last update on 9 Aug 2021. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 9 Aug 2021). 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?

Change of Serum Alkaline Phosphatase (ALP) (time frame: Baseline to week 24.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Aug 2021.
