Read the detailed description

This is a multi-site study with Yale University as the coordinating site. Our research plan is as follows:

Aim 1: To conduct a refined phenotypical and functional analysis of regulatory T cells in study and control patient groups.

Rationale: We would like to extend our preliminary data observations in a larger patient group and use this extended data set to conduct a refined phenotypical and functional analysis of regulatory T cells in order to explore if the regulatory T cell phenotype and function in d-AIH differs: (A) from that in controls defined as (i) non-transplanted patients with autoimmune hepatitis (AIH), (ii) LT recipients with acute rejection, (iii) LT recipients with chronic rejection, (iv) non-transplanted patients with chronic hepatitis C; (B) according to the disease etiology leading to transplantation; (C) according to immunosuppressive regimen prior to diagnosis of d-AIH being made and (D) over time during the disease course. This could potentially give us some insight into the causes for immune tolerance breakdown in d-AIH.

Aim 2: To investigate how over expression of IL-17A and HDAC9 genes relates to the regulatory T cell defect observed in liver transplant recipients with d-AIH.

Rationale: Histone/protein deacetylases regulate chromatin remodeling, gene expression and the functions of many transcription factors. Acetylation of histones leads to an open chromatin structure permissive for the initiation of gene transcription and expression. Histone deacetylase inhibition by Trichostatin-A (TSA) has been demonstrated to prevent the production of IL-17A and sustain Foxp3 expression in human T-regs. Importantly, if differentiation of T-regs into a Th17-like phenotype can be inhibited by TSA in d-AIH, this might be of interest for the development of new therapeutic modalities.

We would like to first of all confirm our preliminary data observations in a larger patient population and address any concerns about RNA integrity in formalin fixed paraffin embedded tissue by using fresh liver biopsy tissue to assess the expression of genes involved in T-cell anergy and immune tolerance in LT recipients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pediatric transplant subject with d-AIHOther

    30 ml of blood will be collected during periods of disease quiescence and activity in recipients with d-AIH who are enrolled. The exact number of blood draws will depend on the patient's pattern of disease activity. No more than one blood draw will take place during an 8-week period. The maximum amount of blood draws over the 2 year study period will be 8.

  • Pediatric transplant subject with acute rejectionOther

    Recipients with acute rejection will have blood drawn at time of diagnosis before treatment for rejection is instituted.

  • Pediatric transplant subject with chronic rejectionOther

    Recipients with chronic rejection will have blood drawn either at diagnosis before treatment is instituted or for those with ongoing chronic rejection at the time of enrollment.

  • Adult non-transplant patients with auto-immune hepatitisOther

    75 ml of blood will be collected during periods of disease quiescence and activity in non transplanted subjects with AIH who are enrolled. Research blood draws will be drawn along with clinical blood draws.

    The exact number of blood draws for each subject will depend on his or her pattern of disease activity. No more than one blood draw will take place during an 8-week period. The maximum amount of blood draws over the 2 year study period will be 8.

    Liver tissue (2 mm) will be obtained at the time a clinically indicated liver biopsy is performed.

    In the event that any enrolled subject undergoes liver transplantation, a portion of the explanted liver will be obtained and stored in special media.

  • Adult non-transplant subjects with chronic hepatitis C virusOther

    For enrolled patients with chronic hepatitis C, 75 ml of blood will be collected before the start of treatment. This will be a onetime blood draw prior to treatment. Liver tissue (2 mm) will be obtained at the time a clinically indicated liver biopsy is performed.

    In the event that any enrolled patient undergoes liver transplantation, a portion of the explanted liver will be obtained and stored in special media.

  • Pediatric control subjectsOther

    2 tablespoons of blood (30 ml) will be collected at each blood draw over a 2-year period. . The maximum amount of blood draws will be 3 however there will be no more than 1 blood draw within an 8-week period.

  • Adult transplanted subjects with de novo autoimmune hepatitisOther

    75 ml of blood will be collected during periods of disease quiescence and activity in recipients with d-AIH who are enrolled. The exact number of blood draws for each subject will depend on his or her pattern of disease activity. However, no more than one blood draw will take place during an 8-week period. The maximum amount of blood draws over the 2-year study period will be 8.

Questions about this trial

What is this clinical trial studying?

An observational study of De Novo Autoimmune Hepatitis, run by Yale University.

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 13 inclusion and 8 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 10 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study was stopped early (reason given: Study PI has moved institutions). Results are not available in the source record.

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?

Liver Allograft Loss (time frame: 3 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?
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 10 Dec 2021.
