Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   31681   clinical trials with a EudraCT protocol, of which   5105   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to evaluate the efficacy of WTX101 for 24 weeks on non-ceruloplasmin-bound copper (NCC) levels adjusted for molybdenum (Mo) plasma concentration in newly diagnosed Wilson Disease (WD) patients aged 18 and older with NCC levels within or above the normal reference range at the time of enrolment.
    E.2.2Secondary objectives of the trial
    - Establish the safety and tolerability of individualised dosing of WTX101 over the course of the study period
    - Evaluate: change in and time to normalisation of NCC levels adjusted for Mo plasma concentration; the effects of WTX101 on neurological status using the UWDRS (neurological subscore; parts I, II and III); the effects of WTX101 on psychiatric status using M.I.N.I. Tracking; the global effects of WTX101 on clinical symptoms as assessed by the Investigators on the CGI scale items 1 (severity of illness) and 2 (global improvement); the effects of WTX101 on the following QoL / PRO endpoint measures: EQ5D, MAQ-8 and the TSQM, the effects of WTX101 on hepatic measures
    - Analyse copper endpoints (exchangeable copper, speciation profiling, and 24-hour urinary copper)
    - Collect PK data on WTX101 in this patient population based on the measurement of plasma total Mo
    - Evaluate the durability, and establish long-term safety and efficacy of WTX101 in a 36 month Extension Phase
