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   37212   clinical trials with a EudraCT protocol, of which   6120   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
    This trial will study the treatment effectiveness of sofosbuvir/velpatasvir for 12 or 24 weeks, in patients infected with genotype 3 hepatitis C virus, with advanced liver disease (cirrhosis), who are slow responders to treatment with persistent virus after the first two weeks of treatment.

    This trial will answer if identifying patients by their viral response during treatment (whether the virus is cleared after the first two weeks) can guide the duration of therapy required to achieve cure.
    E.2.2Secondary objectives of the trial
    This study will compare the tolerability and side effects experienced by patients treated with 12 or 24 weeks of sofosbuvir/velpatasvir. Specifically it will study the frequency of serious adverse events and requirements for stopping treatment prematurely. The study will evaluate quality of life following treatment, using a standardised questionnaire.
