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   41232   clinical trials with a EudraCT protocol, of which   6757   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary efficacy objective of this Phase IIa study is to demonstrate
    the efficacy of once daily dosing of A4250, 1.5 - 3 mg orally during a
    four-week treatment period to relieve patients with Primary Biliary
    Cirrhosis (PBC) from cholestatic pruritus as determined by evaluation of
    effects on pruritus using a visual analogue scale (VAS).

    The primary safety objective of this study is to assess the safety and
    tolerability of A4250, 1.5 - 3 mg orally during a four-week treatment
    period, in patients with PBC and cholestatic pruritus, as determined by
    the occurrence of treatment-emergent SAEs.
    E.2.2Secondary objectives of the trial
    Secondary efficacy objectives of this study are to demonstrate the
    efficacy of A4250 orally on other pruritus variables and on QoL and
    lysophosphatidic acid formation.

    Secondary safety objectives of this study include assessment of the
    safety and tolerability of A4250 during a four-week treatment period, as
    determined by the occurrence of treatment-emergent AEs and changes
    in other safety parameters including liver and kidney function tests and
    vital signs.
