Study summary

The purpose of the registry/repository is to provide a mechanism to store data and specimens to support the conduct of future research about Wilson disease (WD). The overall aim is to determine the optimal testing for diagnosis and parameters for monitoring treatment of WD that will aid product utilization and development.

Read the detailed description

There are three aims outlined as part of this research study.

Aim 1 is to study the natural history of a carefully characterized cohort of patients with WD followed longitudinally at Centers of Excellence for WD in the United States and in the United Kingdom.

Aim 2 seeks to evaluate parameters for diagnosis and treatment monitoring for patients on chelation therapy and zinc treatment for their WD. Data gathered in Specific aim 1 will be used for analyzing the components of the diagnostic scores for patients.

Aim 3 is intended to determine whether a composite index or a biomarker can be used as surrogate marker for treatment monitoring for current patients on therapy that can be used for future patient treatment trials.

Study population

Adult and pediatric patients being evaluated for or with a diagnosis of WD who are willing to participate in the registry at designated study sites around the United States and in the United Kingdom.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Known diagnosis of WD
  • Able and willing to provide for adults (Parental/guardian permission (informed consent) and if appropriate, child assent for participants \<18 (or per local Institutional Review Board (IRB) regulation)

Exclusion criteria

Exclusion Criteria:

  • Diagnosis of WD has been excluded
  • Unwilling to provide or assent
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Create registry for Wilson disease

    This outcome is a binary 'yes/no' outcome as to whether or not this study can successfully create a repository with the intent to store data and specimens to support the conduct of future research on Wilson disease.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
