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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    General information about the trial
    Main objective of the trial
    The primary objective of this study was to evaluate the effect of 12 weeks of subcutaneous evolocumab once a month (QM) compared with placebo QM on percent change from baseline in low-density lipoprotein cholesterol (LDL-C) in subjects with type 2 diabetes mellitus and hypercholesterolemia or mixed dyslipidemia on maximally tolerated dose of statin of at least moderate-intensity oral daily.
    Protection of trial subjects
    This study was conducted in accordance with International Council for Harmonisation (ICH) Good Clinical Practice (GCP) regulations/guidelines, and Food and Drug Administration (FDA) regulations and guidelines set forth in 21 Code of Federal Regulations parts 11, 50, 54, 56, and 312. The study and all amendments were reviewed by an Independent Ethics Committee (IEC) or Institutional Review Board (IRB) at each center. The investigator or his/her designee informed the subject of all aspects pertaining to the subject’s participation in the study before any screening procedures were performed.

    Recruitment
    Recruitment details
    Of 853 patients screened, a total of 424 participants were randomized at 58 centers in Belgium, Canada, Italy, Mexico, Poland, Spain and the United States from 17 May 2016 to 05 May 2017.

    Pre-assignment
    Screening details
    Participants received subcutaneous placebo during a 6-week screening period. Participants who completed the screening period and met final eligibility criteria were randomized in a 1:2 ratio to placebo or evolocumab. Randomization was stratified by low-density lipoprotein cholesterol (LDL-C) level (> or < 130 mg/dL).

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    06 Jan 2016
    - clarified timing of randomization in relation to first dose. - added clarification that subjects must tolerate SC injection of placebo with device anticipated to be used (either AI/pen or AMD) - added clinical research associate as an additional contact for the investigator prior to unblinding of subject’s treatment assignment. - added non-clinic investigational product injection at Week 4 to the Schedule of Assessments table for clarity. - removed text specifying kilograms and centimeters for body weight and height so sites can record in pounds and inches. - added that triglycerides > 1000 mg/dL would be reported to the investigators to allow appropriate follow-up to be initiated. - revised reasons for removal from treatment to be consistent with template text. - updated reporting requirements for adverse events for consistency throughout the protocol. - added appendix E of Child-Pugh Score to provide additional information.
