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   43387   clinical trials with a EudraCT protocol, of which   7179   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.3Principal inclusion criteria
    -Completed Study Nef-301, defined as Part A (9-month study drug treatment [Nefecon 16 mg/day or placebo] and 3-month follow-up) and Part B (12-month follow-up);
    -Completed Visit 17b in Study Nef-301 within 3 months before Study Visit 3;
    -On a stable dose of RAS inhibitor therapy (ACEIs and/or ARBs) at the maximum allowed dose or maximum tolerated dose according to the 2012 KDIGO guidelines21 (see Appendix C). A stable dose is defined as a dose within 25% of the dose at Visit 17a or 17b in Study Nef 301; and
    -Proteinuria based on 2 consecutive measurements (24-hour urine sampling) after informed consent, separated by at least 2 weeks and calculated by the central laboratory. Both samples of the same parameter must show either of the following:

    oUPCR >/=0.8 g/gram (90 mg/mmol) in 2 consecutive measurements; and
    -eGFR >/=30 mL/min per 1.73 m2 using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula confirmed by the central laboratory at Study Visit 1 or Study Visit 3.
