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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    General information about the trial
    Main objective of the trial
    The primary objective of the study was to demonstrate that bosutinib reduces the rate of kidney enlargement in subjects with Autosomal Dominant Polycystic Kidney Disease (ADPKD) entering the study with total kidney volume (TKV) >=750 cc and estimated glomerular filtration rate (eGFR) 60 >=mL/min/1.73m2.
    Protection of trial subjects
    An independent external Data Monitoring Committee (eDMC) reviewed accumulating safety data on an ongoing basis. The eDMC may have, at any time, requested additional information from the sponsor. Based on these reviews, the eDMC had capacity to make recommendations to the sponsor that might impact the future conduct of the study. These may have included continuing the study as planned, amending safety-monitoring procedures, modifying the protocol or consent, or terminating the study. In addition, the eDMC was responsible for reviewing the safety and efficacy data for the interim analysis.

    Change From Baseline in Kidney Disease Quality of Life (KDQoL)-36 Scale Scores at Month 25
    End point description
    The KDQoL-36 is a 36-item questionnaire on kidney disease-specific measure of patient-reported quality of life with 5 subscales: physical and mental functioning (items 1-12); burden of kidney disease subscale (Burden, items 13-16); symptoms and problems (items 17-28); effects of kidney disease on daily life subscale (KDQoL, items 29-36). The raw scores are transformed linearly to a range of 0 to 100, with higher scores indicating better quality of life. M25=Month 25.
