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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    General information about the trial
    Main objective of the trial
    The main objective of the trial was to assess the efficacy based on the percentage of subjects with sustained virologic response for 12 weeks (SVR12), in both the global and site-specific cohorts.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Conference on Harmonization Good Clinical Practice Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.

    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: The number of subjects reported in the baseline period are different from the worldwide number enrolled in the trial as 49 subjects discontinued from the study due to various reasons.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    06 Jan 2012
    The 48-week post-treatment follow-up period was reduced to 24-weeks, revised treatment population, primary endpoint to additionally specify that they include subjects that are prior non-responders to pegINFalfa-2a/RBV, revised the on treatment futility rules from the Week 4 and Week 12 criteria to a Week 8 Futility only that includes any detectable Hepatitis C virus (HCV) RNA (>=lower limit of quantification) results after Week 8 (with no confirmation HCV RNA value required), revised the futility rule definitions, revised the definition of a relapse, revised the wording regarding the timing of the 1st interim analysis, reduced the safety endpoint measurements from the last dose of study drug therapy from 30-days to 7-days for treated subjects and wording modifications designed to clarify or correct inconsistencies in the protocol procedures.
    20 Mar 2012
    Removed Week 8 treatment futility rule of genotype-(GT)-2 and GT-3 subjects, updated futility rule to Week 8 for GT-1 and GT-4 subjects and added that confirmation of HCV RNA is required within 2 weeks of Week 8 result, updated definition of virologic breakthrough, updated study design to allow rollover of treatment naive GT-1b subjects assigned to the placebo arm in AI447028 who were treated with the combination of asunaprevir and daclatasvir therapy, these subjects met pre-defined rescue therapy criteria and could have been treated with daclatasvir/asunaprevir/pegIFNalfa/RBV therapy (daclatasvir and asunaprevir plus pegIFNalfa-2a/RBV) for 24 weeks at the discretion of the investigator, added new formulation of 60 mg tablets daclatasvir and 100 mg capsules of asunaprevir, updated reasons for discontinuation from treatment, updated rules for dose modifications and interruptions, revised timing of primary objective to SVR12, revised sample size of HCV GT-1 or -4 subjects who were prior non-responders to pegIFNalfa-2a/RBV, added sample size for HCV GT-1b treatment-naive subjects, updated interim and final analysis based on SVR12 rate instead of SVR24.
    25 May 2012
    Added new safety information as well as guidance regarding the management of subjects exposed to combination therapy with asunaprevir and daclatasvir who present with unexplained pyrexia.
    20 Nov 2012
    Clarified that women of child bearing potential (WOCBP) and men who were sexually active with WOCBP who rolled over from Study AI447028 and took daclatasvir/asunaprevir therapy were to use 1 method of contraception throughout the study and for a minimum of 12 weeks after discontinuation of ASV and DCV. Oral contraceptive pills were allowed but were not considered an effective form of contraception.
    13 Jun 2013
    Revised guidance for contraception for WOCBP and male subjects sexually active with WOCBP and added the option to treat subjects receiving rescue therapy for either 24 or 48 weeks.
