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   40669   clinical trials with a EudraCT protocol, of which   6638   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.2 Objective of the trial
    E.2.1Main objective of the trial
    To determine if patiromer treatment of subjects who developed hyperkalemia while receiving RAASi medications will result in continued use of RAASi medications in accordance with heart failure (HF) treatment guidelines and thereby decrease the occurrence of the combined endpoint of cardiovascular (CV) death and CV hospitalization events compared with placebo treatment.
    Determinar si el tratamiento con patirómero en sujetos que hayan desarrollado hiperpotasemia mientras recibían medicamentos iSRAA provocará la continuación del uso de medicamentos iSRAA de acuerdo con las directrices para el tratamiento de la insuficiencia cardíaca (IC) y, por lo tanto, reducir la incidencia del criterio de valoración combinado de episodios de muerte cardiovascular (CV) y acontecimientos de hospitalización CV en comparación con el tratamiento con placebo.
