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   44334   clinical trials with a EudraCT protocol, of which   7366   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.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time
    Merck condurrà una Ricerca Biomedica Futura su campioni di DNA (estratti dal sangue) raccolti nel corso di questo studio clinico. Tale ricerca ha lo scopo di esaminare vari biomarcatori per rispondere a domande che stanno emergendo e che non sono descritte in altre parti del protocollo (nell’ambito dello studio principale), e verrà condotta solo su campioni di soggetti che abbiano rilasciato apposito consenso. L'obiettivo della raccolta dei campioni per la Ricerca Biomedica Futura è quello di esplorare e identificare biomarcatori che contribuiscano scientificamente alla comprensione delle malattie e/o della relative terapie. L'obiettivo ultimo è quello di utilizzare tali informazioni per sviluppare farmaci più sicuri e più efficaci, e/o per garantire che i soggetti ricevano la dose giusta del giusto farmaco al momento giusto.

    • Positive for anti-HCV antibody, HCV RNA, or any of the above HCV genotypes at least 6 months before screening, or
    • Positive for anti-HCV antibody or HCV RNA at the time of screening with a liver biopsy consistent with chronic HCV infection (or a liver biopsy performed before enrollment with evidence of CHC disease, such as the presence of fibrosis)
    4. have evidence of hepatic cirrhosis with a score on the Child-Pugh scale from 7 to 9 (moderate hepatic insufficiency) at the time of screening and not anticipated to receive a liver transplant within the next 36 weeks
