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 primary objectives for this study are: 1) To show superiority of a 0.1 mmol/kg dose of MULTIHANCE as compared to 0.1 mmol/kg dose of DOTAREM, in terms of the by-subject global diagnostic preference between exams (i.e., based on pre-dose plus post-dose image sets). 2) To show superiority of a 0.05 mmol/kg dose of MULTIHANCE as compared to 0.1 mmol/kg dose of DOTAREM, in terms of the by-subject global diagnostic preference between exams (i.e., based on pre-dose plus post-dose image sets).
    Protection of trial subjects
    This study was conducted in compliance with Title 21, CFR Part 50, CFR Part 56, and CFR Part 312, with the ethical principles that have their origin in the Declaration of Helsinki (adopted by the 18th World Medical Association [WMA] General Assembly in Helsinki, Finland [June 1964] and amended by the 29th WMA in Tokyo, Japan [October 1975], by the 35th WMA in Venice, Italy [October 1983], by the 41st WMA in Hong Kong [September 1989], by the 48th WMA in Somerset West, Republic of South Africa [October 1996], by the 52nd WMA in Edinburgh, Scotland [October 2000], with note of clarification by the 53rd WMA in Washington DC, United States [2002] and the 55th WMA in Tokyo, Japan [2004], and by the 59th WMA in Seoul, Korea [October 2008]). In addition, this study was conducted in compliance with Good Clinical Practices (GCP) as outlined in ICH E6 (Good Clinical Practice: Consolidated Guideline).

    Recruitment
    Recruitment details
    A total of 179 patients were recruited from February 2014 through February 2015 at 14 clinical trial sites. Off-site assessment of the images was performed between 19 February - 17 March 2015 by 3 board-certified neuroradiologists blinded as to which contrast agent was used, patient clinical information, and the results of other imaging studies.

    Pre-assignment
    Screening details
    179 patients were enrolled and signed informed consent. Each enrolled patient was randomized and 177 were dosed with at least one contrast agent.

    Blinding implementation details
    In this double-blind, two-arm study, the Investigator and the patient were blinded to the investigational product administered for Exam 1 and for Exam 2. A computer generated randomization code list was provided by the Sponsor to each site for the assignment of study arm as well as for the assignment of investigational product. Patients from the 2 arms were mixed in one randomization list.

    Global Diagnostic Preference Between the Two Exams
    End point description
    Assessed by 3 blinded readers for each of the 159 patients who had post-dose exams for both MultiHance, 0.1 mmol/kg and 0.05 mmol/kg doses, and Dotarem 0.1 mmol/kg. Readers assessed whether images with MultiHance were preferred or images with Dotarem were preferred, or whether images after both exams were considered equal. An image set deemed technically inadequate by a blinded reader was excluded from efficacy analysis for that specific reader. Therefore, the number of participant exams evaluated by each reader differed slightly across readers and endpoints. The 3 blinded readers assessed the available image sets as technically adequate in 84.3-90.7% of cases, depending on reader and study arm.

    Extent of Disease
    End point description
    Assessed by 3 blinded readers for each of the 159 patients who had post-dose exams for both MultiHance, 0.1 mmol/kg and 0.05 mmol/kg doses, and Dotarem 0.1 mmol/kg. Readers assessed whether images with MultiHance were preferred or images with Dotarem were preferred, or whether images after both exams were considered equal. An image set deemed technically inadequate by a blinded reader was excluded from efficacy analysis for that specific reader. Therefore, the number of participant exams evaluated by each reader differed slightly across readers and endpoints. The 3 blinded readers assessed the available image sets as technically adequate in 84.3-90.7% of cases, depending on reader and study arm.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    25 Jun 2014
    The final protocol (dated 10 September 2013) was amended on 25 June 2014 (Protocol Amendment 1). There were seven changes to the protocol as described in Amendment 1: RATIONALE 1. The Sponsor physical address had changed. Cover pages in Protocol and Synopsis and Appendix G in the protocol were updated to reflect this change. 2. In addition to centers in North America and Europe, the Protocol was revised to allow centers also in Latin America. 3. The reference documents for the storage of the contrast agents for Latin America were added to the Storage Section (Sect. 6.2) of the Protocol 4. Table D was corrected to state that Parallel Image acquisitions are not permitted for T1 pre and post IP injection sequences, but for the T2 pre and post IP injections sequences, Parallel Imaging acquisitions could be used. 5. The Bracco personnel in Serious Adverse Event Sponsor Contact Personnel were changed. The ‘Serious Adverse Event Contact Personnel Table’ was changed in the Protocol to reflect these changes. 6. The following was added to Appendix B for Latin America: MultiHance ‘Sample Vial Label,’ ‘Dotarem Sample Vial Label,’ and ‘Sample Medication Box Label.’ 7. CRO Contact information was added to the Administrative Structure for Europe (Appendix H in the Protocol) for Ecron Acunova, the designated monitoring CRO for European sites in this study. Contact information for Clinical Research Personnel in Latin America was also added to the Administrative Structure.
