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   43861   clinical trials with a EudraCT protocol, of which   7284   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)
    Primary Safety Endpoint
    Nature and proportion of AEs between PLN-74809 and placebo groups (descriptive)
    Safety data from all participants who received at least one dose of study drug will be incorporated into the final safety analysis. Further details of the safety analyses will be provided in the SAP. AEs will be collected from the time the participant signs the ICF until the last study visit. Treatment-emergent adverse events (TEAEs) are defined as AEs that emerged or worsened in severity after the first administration of study drug
    E.5.1.1Timepoint(s) of evaluation of this end point
    AEs will be collected from the time the participant signs the ICF until the last study visit.
    E.5.2Secondary end point(s)
    a. Secondary Pharmacokinetic Endpoints
    Plasma PLN-74809 concentrations at each sampling time point will be presented in listings and descriptive summary statistics by dose and visit. The data will also be presented graphically.
    Further details of the analyses will be provided in the SAP to be prepared and agreed prior to final ‘database lock’ at the end of the study. The PK analysis plan and report may be prepared separately from the SAP as appropriate.
    b. Secondary Pharmacodynamic Endpoints
    Saliva, urine, plasma and serum samples will be analyzed for biomarkers (presence or actual concentration). These samples will be used to determine the levels of these markers in participants and the relationship between these markers. Results will be presented by listings, descriptive summary statistics and in graphical form by treatment and dose and expressed as the relative change (and or absolute) for each participant.

    In addition, relationships between PK and PD may be evaluated in an exploratory fashion and presented in graphical manner.
