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   43858   clinical trials with a EudraCT protocol, of which   7284   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 ).

    Clinical Trial Results:
    A Phase III, Randomized, Double-Blind, Active Comparator-Controlled Parallel-Group Study, Conducted Under In-House Blinding Conditions, to Examine the Efficacy and Safety of a Single 150 mg Dose of Intravenous Fosaprepitant Dimeglumine for the Prevention of Chemotherapy-Induced Nausea and Vomiting (CINV) Associated with Moderately Emetogenic Chemotherapy

    Due to the EudraCT – Results system being out of service between 31 July 2015 and 12 January 2016, these results have been published in compliance with revised timelines.

    General information about the trial
    Main objective of the trial
    This study aims to demonstrate that, when given concomitantly with a 5-hydroxytryptamine 3 (5-HT3) antagonist and a corticosteroid, a single 150 mg intravenous (IV) dose of fosaprepitant given on Day 1 is superior to the control regimen of 5-HT3 antagonist and corticosteroid only, in preventing chemotherapy-induced nausea and vomiting (CINV) associated with moderately emetogenic chemotherapy (MEC).
    Protection of trial subjects
    This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research. The following additional measure defined for this individual study was in place for the protection of trial subjects: Rescue medication was allowed for established cases of nausea or vomiting.

    Recruitment
    Recruitment details
    		 Males and females who were ≥18 years old and were scheduled to receive MEC were enrolled into this study. Additional inclusion and exclusion criteria applied.

    Pre-assignment
    Screening details
    		 A total of 14 participants were randomized but did not receive study drug. The source documents for one additional participant were lost. One participant was randomized to receive Control Regimen, but actually received Fosaprepitant Regimen. Disposition is by actual treatment group and not by randomized treatment group.
