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 ).

    General information about the trial
    Main objective of the trial
    To assess the effect of imeglimin versus placebo on glucose tolerance during a 3-hour Oral Glucose Tolerance Test (OGTT) after 18 weeks of treatment in type 2 diabetic subjects.
    Protection of trial subjects
    Subjects provided their written consent to participate in the study after having been informed about the nature and purpose of the study, participation/termination conditions, and risks and benefits of treatment. The subject information sheet in the local language and prepared in accordance with the ICH GCP guidance was provided by the sponsor for the purpose of obtaining informed consent. The subject’s written informed consent to participate in the study must have been given before any study-related activities were carried out. Whenever important new information became available that was relevant to the subject’s consent, the written subject information sheet and any other written information provided to subjects were revised by the Sponsor and submitted again to the IEC/IRB for review and favourable opinion. The agreed, revised information was forwarded to each subject in the study. The Investigator explained the changes to the previous version and the subject was asked to sign the new version. Subjects were free to discontinue the study at any time without giving their reasons. To overcome the risk to expose T2DM subjects to inappropriate glycaemic levels, some proactive measures were implemented. First, the upper level of HbA1c inclusion criteria at randomisation was limited to 9.5% to avoid highly uncontrolled subjects entering the study. Second, fasting plasma glucose [FPG] was closely monitored throughout the study by the subject (glucometer) and by the Investigator at each visit and whenever necessary. Thresholds were defined following the Food and Drug Administration (FDA) guidance to withdraw subjects whose glycaemic parameters continued to deteriorate during the study period so that rescue therapy could be initiated.
    Background therapy
    No background therapy was allowed during the study.
    Evidence for comparator
    This mechanistic study was designed to evaluate the efficacy of imeglimin on both fasting and postprandial glycaemic control compared to placebo after 18 weeks of treatment duration, and their respective participation in decreasing HbA1c.
