Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43851   clinical trials with a EudraCT protocol, of which   7283   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).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Primary biliary cholangitis (PBC, formerly known as primary biliary
    cirrhosis) is a serious and potentially life threatening autoimmune
    disease of the liver characterized by impaired bile flow (cholestasis) and accumulation of toxic bile acids (BA).
    E.1.1.1Medical condition in easily understood language
    Disease of the liver
    E.1.1.2Therapeutic area Body processes [G] - Immune system processes [G12]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to evaluate the treatment effect of seladelpar on composite biochemical improvement in cholestasis markers based on ALP and total bilirubin and to evaluate the safety of seladelpar over 12 months of treatment compared to placebo.
    E.2.2Secondary objectives of the trial
    The key secondary objectives of this study are to evaluate the effect of seladelpar on the normalization of ALP values at 12 months of treatment compared to placebo and to evaluate the effect of seladelpar on pruritus at 6 months of treatment compared to placebo in subjects with baseline moderate to severe pruritus.
    Other secondary objectives of the study are to evaluate the effect of seladelpar on other measures of cholestasis, metabolic markers, and PBC prognostic criteria; to evaluate the effect of seladelpar on quality of life (QoL); and to evaluate the effect of seladelpar on PBC-associated clinical outcomes.
