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   44339   clinical trials with a EudraCT protocol, of which   7369   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 Objective of the trial
    E.2.1Main objective of the trial
    To compare the efficacy of tenofovir DF 300 mg QD versus adefovir dipivoxil 10 mg QD for the treatment of HBeAg positive chronic hepatitis B. The primary efficacy parameter is the proportion of patients with complete response at week 48, i.e., serum HBV DNA levels below 400 copies/mL and histologic improvement defined as at least a 2 point reduction in the Knodell necroinflammatory score without worsening in the Knodell fibrosis score.

    To compare the safety and tolerability of tenofovir DF 300 mg versus adefovir dipivoxil 10 mg.
    E.2.2Secondary objectives of the trial
    To evaluate the incidence of drug-resistant mutations in the treatment arms.

    To compare the virologic, biochemical, serological and histologic response to tenofovir DF 300 mg versus adefovir dipivoxil 10 mg for the treatment of HBeAg positive chronic hepatitis B.
    E.2.3Trial contains a sub-study Information not present in EudraCT

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy parameter is the proportion of patients treated with tenofovir DF 300 mg QD versus adefovir dipivoxil 10 mg QD with complete response at week 48 (serum HBV DNA levels below 400 copies/mL and histologic improvement defined as at least a 2 point reduction in the Knodell necroinflammatory score without a worsening in the Knodell fibrosis score) at the end of the double blind treatment period.

    F.3.3.1Women of childbearing potential not using contraception For clinical trials recorded in the database before the 10th March 2011 this question read: "Women of childbearing potential" and did not include the words "not using contraception". An answer of yes could have included women of child bearing potential whether or not they would be using contraception. The answer should therefore be understood in that context. This trial was recorded in the database on 2006-05-17. Yes

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    While the protocol GS-US-174-0103 is designed as a 48 weeks study, Gilead has made the commitment to extend the treatment duration for all subjects, completing the week 48 liver biopsy, an additional 192 weeks. This will enable subjects to receive active treatment for a total of 240 weeks. The extension of the treatment duration will be submitted via an amendment for your review, well in advance of the first subject reaching week 48.
