Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   37571   clinical trials with a EudraCT protocol, of which   6160   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    For biomarker risk algorithm qualification:
    -To qualify the biomarker risk algorithm composed of TOMM40 rs10524523 genotype, APOE genotype, and age for prognosis of the risk of developing MCI due to AD within 5 years.

    For efficacy evaluation of pioglitazone:
    - To evaluate the efficacy of pioglitazone compared with placebo to delay the onset of MCI due to AD in cognitively-normal subjects who are at high-risk, as identified by the biomarker risk algorithm at enrollment, for
    developing MCI due to AD within 5 years.
    E.2.2Secondary objectives of the trial
    -To evaluate the effect of pioglitazone compared with placebo on the progression of cognitive decline.
    -To evaluate the effect of pioglitazone compared with placebo on functional decline and instrumental activities of daily living.

    E.5 End points
    E.5.1Primary end point(s)
    For biomarker risk algorithm qualification:
    -Time to diagnosis of MCI due to AD for placebo-treated, high-risk, non-Hispanic/Latino Caucasian subjects versus placebo-treated, low-risk, non-Hispanic/Latino Caucasian subjects.

    For efficacy evaluation of pioglitazone:
    Time to diagnosis of MCI due to AD for pioglitazone-treated, non-Hispanic/Latino Caucasian subjects versus placebo-treated non-Hispanic/Latino, Caucasian subjects in the high-risk stratum.
    E.5.1.1Timepoint(s) of evaluation of this end point
    MCI event could occur at any time during the study, so there is no fixed timepoint for evaluation of an individual event.
    E.5.2Secondary end point(s)
    -Change from baseline for cognitive decline on composite score on the cognitive battery for pioglitazone-treated subjects versus placebo-treated subjects in the high-risk stratum.

    - Changes from baseline in instrumental activities of daily living (Alzheimer’s Disease Cooperative Study Activities of Daily Living - Prevention Instrument [ADCS ADL-PI]) between pioglitazone-treated and placebo-treated groups of the high-risk stratum.
    E.5.2.1Timepoint(s) of evaluation of this end point
