Clinical Evaluation and Assessment of Instruments and Biomarkers in Subjects With Wilson Disease

Overview

The primary objective of the study is to determine the relevance and appropriateness of outcome assessments, including biomarkers, within the Wilson disease population to inform study design and endpoint selection for future clinical studies.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: March 2021

Detailed Description

Given the limited information on the frequency and spectrum of disease manifestations and clinical course of Wilson disease, the UX701-CL001 study aims to assess the utility and feasibility of various assessments and biomarkers to inform endpoint selection for future clinical studies, better understand the relationship between biomarkers and potential clinical outcomes, and characterize the clinical presentation of Wilson disease. UX701-CL001 is a clinical survey study. Subjects will complete assessments at the study site and at home to evaluate the clinical manifestations of Wilson disease in clinical and real-world environments.
