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   35177   clinical trials with a EudraCT protocol, of which   5751   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.1.1.1Medical condition in easily understood language
    Acral Pustular Psoriasis (APP) is a rare, chronic inflammatory skin disease characterised by sore, red skin covered in pustules involving the hands and feet.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To determine the efficacy of anakinra in treatment of adults with PPP compared to placebo. The primary endpoint is change in disease activity over 8 weeks, adjusted for baseline (visit 1), measured using fresh pustule count, the default primary outcome, unless PPPASI is more discriminating (to be reviewed at the end of stage one).

    The Stage 1 review occurred on 22nd January 2018. As a result of this review the DMC recommended the primary outcome to be PPPASI and this was passed by the TSC. Fresh pustule count will be a secondary outcome.

    E.2.2Secondary objectives of the trial
    - describe any treatment effect of anakinra, indicated by change in disease activity over 8 weeks using the Palmoplantar Pustulosis Psoriasis Area Severity Index (PPPASI)
    - determine the following:
    - time to response of PPP and relapse rate with anakinra
    - proportion of randomised patients achieving clearance of PPP with anakinra by 8 weeks
    - any treatment effect of anakinra in pustular psoriasis at non acral sites as measured by change in percentage area of involvement at 8 weeks
    - any treatment effect of anakinra in plaque type psoriasis (using Psoriasis Area and Severity Index (PASI) at 8 weeks)
    - collect data on the adverse event profile and adverse reactions induced by anakinra to evaluate the safety and tolerability of anakinra
    - the impact of anakinra on patients' symptoms and quality of life
    - the proportion of randomised patients who find the treatment acceptable or worthwhile
    - the proportion of randomised patients adhering to treatment
    E.2.3Trial contains a sub-study No

    xiv. Unable to comply with the study visit schedule
    E.5 End points
