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   38514   clinical trials with a EudraCT protocol, of which   6328   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.

    General information about the trial
    Main objective of the trial
    The primary objective of this study was to assess the pharmacokinetics of doripenem after a single administration of 30 milligram per kilogram of body weight (mg/kg) of doripenem as 4 hour intravenous (IV) infusion administered to paediatric subjects with cystic fibrosis (CF).
    Protection of trial subjects
    This study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and that are consistent with Good Clinical Practices and applicable regulatory requirements. Safety was assessed based on treatment-emergent adverse events (TEAEs), including pre-study to post-study changes in physical examination findings, vital sign measurements, and clinical laboratory analyte values. A safety committee was established to ensure that the safety of the subjects was not compromised.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    18 Feb 2009
    Protocol amendment 1 included revision of inclusion criterion to allow the flexibility to enroll subjects receiving antibiotic therapy outside the hospital and also for the subjects receiving antibiotics without an IV catheter in place. Withdrawal criterion for interrupted doripenem infusion was modified from interruption more than 5 minutes to more than 10 minutes.
    22 Jun 2009
    Protocol amendment 2 included withdrawal from study was modified to allow re-enrollment of subjects withdrawn for reasons other than safety. Instructions regarding pharmacokinetic sample collection in the cases where study drug administration could have been interrupted for less than or equal to 10 minutes were clarified.
    01 Oct 2009
    Protocol amendment 3 deleted an inclusion criterion for weight requirement (within the 5th and the 95th percentile), to allow enrollment of subjects with lower body weight. Study withdrawal section and dosage and administration section were updated to clarify that the subject was to be withdrawn if the total interruption in study drug administration occurred for more than 10 minutes.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
