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   44339   clinical trials with a EudraCT protocol, of which   7369   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.

    E.5 End points
    E.5.1Primary end point(s)
    Efficacy:
    Efficacy outcome measures in this study include the following:
    1. Co-primary outcome measures in this study:
    a. A comparison between the mean change from Baseline to Week 52 in the Dimebon 20 mg TID treatment group and the placebo group on the ADAS-cog;
    b. A comparison between the mean change from Baseline to Week 52 in the Dimebon 20 mg TID treatment group and the placebo group on the ADCS-ADL;

    E.5.1.1Timepoint(s) of evaluation of this end point
    • Twelve months
    E.5.2Secondary end point(s)
    2. Key secondary outcome measures in this study include:
    a. A comparison between the mean change from Baseline to Week 52 of the Dimebon 20 mg TID treatment group and the placebo group on the Clinician's Interview Based Impression of Change, plus caregiver input (CIBIC-plus);
    b. A comparison between the mean change from Baseline to Week 52 of the Dimebon 20 mg TID treatment group and the placebo group on the NPI;
    f. RUD Lite© and EQ-5D data summarized descriptively by treatment group.
    Safety:
    The safety of Dimebon will be assessed by the frequency of serious adverse events, the frequency of discontinuation of Dimebon treatment due to an adverse event, the frequency and severity of adverse events, as well as the frequency of new laboratory and ECG abnormalities among the three treatment groups. Safety measures thus include adverse events, vital signs, physical examinations, ECGs, and clinical laboratory testing.
    Pharmacokinetics:
    Dimebon plasma concentrations will be measured at Baseline and Week 13. The impact of covariates will be evaluated in order to identify underlying factors responsible for the variability of PK parameters and to identify sub-populations.
