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   43873   clinical trials with a EudraCT protocol, of which   7292   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.

    L’obiettivo primario è quello di confrontare due regimi di somministrazione profilattica di BAX 855 mirati a ottenere due diversi livelli minimi di FVIII, confrontando le proporzioni di soggetti che raggiungono un tasso emorragico annuale (annualized bleeding rate, ABR) totale di 0 nel secondo periodo di studio di 6 mesi.
    The primary objective of the study is to compare two prophylactic dosing regimens of BAX 855 targeting two different FVIII trough levels, by comparing the proportions of subjects achieving a total ABR of 0 in the second 6-month study period.
    E.2.2Secondary objectives of the trial
    To compare the two prophylactic dosing regimens of BAX 855 targeting two different FVIII trough levels with respect to the following:
    Proportion of subjects in each prophylactic dosing arm achieving a spontaneous ABR and spontaneous AJBR of 0 in the second 6-m period
    Proportion of subjects in each prophylactic dosing arm with a total, spontaneous ABR and AJBR <2
    Total, spontaneous, and trauma-related ABRs in the 12-m period Reduction in ABR between the two treatment arms and the historical ABR prior to study enrolment
    Total weight-adjusted consumption of BAX 855 for each prophylactic regimen
    Joint status using the HJHS and over time
    HRQoL / Pharmacoeconomic outcomes
