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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    4. Participants must meet the following criteria for hyperkalaemia:
    For participants aged ≥ 2 years, Local Laboratory S-K+ level > 5.0 mmol/L, for participants aged 1 month to < 2 years, Local Laboratory S-K+ level >6.0 mmol/L and for participants aged 0 to < 1 month, Local Laboratory S-K+ level > 6.5 mmol/L at Screening, measured 3 to 14 days prior to first dose of SZC on CP Study Day 1. This should also be confirmed prior to dosing on Day 1.

    (a) For participants aged 0 to ≤3 days after birth: <450 ms
    (b) For participants aged >3 days to <12 years: <440 ms
    (c) For participants aged ≥ 12 to < 18 years: < 450 ms (male), < 460 ms (female)
    All QTcB values outside the reference values specified in the protocol should be manually re measured and re-calculated, and if there is a difference in measurement between the automatic and manual ECG, the manual measurement should always be considered correct.

Esto también debe confirmarse antes de la administración del día 1.

    5. Utilizando un ECG digital, el intervalo QT corregido mediante el método de Bazett (QTcB) debe cumplir los parámetros adecuados a la edad en la selección:
    a. Para participantes de 0 a ≤ 3 días después del nacimiento: < 450 ms
    b. Para participantes de > 3 días a < 12 años: < 440 ms
    c. Para participantes de ≥ 12 a < 18 años: < 450 ms (niños), < 460 ms (niñas)
