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   42567   clinical trials with a EudraCT protocol, of which   7008   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    General information about the trial
    Main objective of the trial
    The primary objectives of this study are to compare the efficacy of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks with that of sofosbuvir (SOF) + ribavirin (RBV) for 24 weeks and to evaluate the safety and tolerability of each treatment regimen in participants with chronic genotype 3 hepatitis C virus (HCV) infection.
    Protection of trial subjects
    The protocol and consent/assent forms were submitted by each investigator to a duly constituted Independent Ethics Committee (IEC) or Institutional Review Board (IRB) for review and approval before study initiation. All revisions to the consent/assent forms (if applicable) after initial IEC/IRB approval were submitted by the investigator to the IEC/IRB for review and approval before implementation in accordance with regulatory requirements. This study was conducted in accordance with recognized international scientific and ethical standards, including but not limited to the International Conference on Harmonization guideline for Good Clinical Practice (ICH GCP) and the original principles embodied in the Declaration of Helsinki.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 6 participants (SOF/VEL 12 Weeks = 1; SOF+RBV 24 Weeks = 5) who were randomized but not treated are not included in the subject disposition table.

    Non-Inferiority Analysis - SVR12
    Statistical analysis description
    Primary analyses consisted of non-inferiority test of Group 1 (SOF/VEL 12 weeks) versus Group 2 (SOF+RBV 24 weeks) at the 0.05 significance level. Non-inferiority was assessed using the conventional confidence interval approach and a non-inferiority margin of 10% was applied. The two-sided 95% confidence intervals was constructed using stratum-adjusted Mantel-Haenszel proportions, stratified by the randomization stratification factors (i.e cirrhosis status and prior treatment experience)
