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   44334   clinical trials with a EudraCT protocol, of which   7366   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)
    The co-primary parameters for this study are the Severe Impairment Battery (SIB) change from Baseline and the CIBIC+ change from Baseline in the Intent to Treat population using Last Observation Carried Forward (ITT-LOCF) imputation for missing data. For registration applications in Europe, the ADCS-ADL will replace the CIBIC+ as the second co-primary parameter. Severe Impairment Battery (SIB) The SIB will be administered to patients during the Screening and Baseline Visits and at the 6-, 12-, 18- and 24-week visits. It is essential that the SIB be completed in its entirety at Baseline. If for any reason this assessment is not completed at this visit, the patient will be discontinued. Modified Alzheimer’s Disease Cooperative Study Activities of Daily Living (ADCS-ADL). The ADCS-ADL (severe scale) consists of a comprehensive battery of ADL questions used to measure a patient’s functional capabilities. The modified ADCS-ADL-severe scale is a 19-item scale that has been validated for the assessment of patients with moderate to severe dementia. It measures the most appropriate basic and instrumental abilities (such as walking, grooming, bathing, and eating) in this patient population. Each ADL item is rated from the highest level of independent performance to complete dependence. The scale has a scoring range of 0 to 54, with the lower scores indicating greater functional impairment. This inventory will be administered at Baseline and at the 6-, 12-, 18-, and 24-week (or early termination) visits as a rater-administered interview with the caregiver, and will cover the patient’s most typical and consistent performance of each ADL during the previous 4 weeks. It is essential that the ADCS-ADL be completed in its entirety at Baseline. If for any reason this assessment is not completed at this visit, the patient will be discontinued.
