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   40165   clinical trials with a EudraCT protocol, of which   6574   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.

    10. Subjects have used unfractionated heparin within 24 hours prior to treatment and have an elevated partial thromboplastin time.
    11. Subjects have used a nonvitamin K antagonist oral anticoagulant such as dabigatran, rivaroxaban, apixaban, or other factor Xa inhibitors within 24 hours prior to treatment.
    12. Subjects have used fondaparinux or low molecular weight heparin at an anticoagulation dose within 24 hours prior to treatment.

    E.5 End points
    E.5.1Primary end point(s)
    • Safety parameters:
    Safety parameters will include adverse events occurrence,physical examination findings, vital sign measurements, standard clinical laboratory parameters (including serum chemistry, hematology, urinalysis, and coagulation parameters), and electrocardiogram (ECG) parameters.
    Other safety parameters will include bleeding events and neurologic function. Bleeding events will be assessed and categorized as sICH, any intracranial hemorrhage (ICH), or non-ICH major bleeding. Neurologic function will be measured using the NIHSS.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Day 1, day 2, day 3, day 4, day 5 and at follow up (day 30 and day 90).
    E.5.2Secondary end point(s)
    • Pharmacokinetic parameters:
    Standard noncompartmental PK parameters will be assessed. Plasma samples for PK assessments will be taken at multiple timepoints in the study. Additionally, a PK sample may also be obtained outside of the specified timepoints during the study if deemed clinically necessary. Urine PK samples will also be collected and evaluated in the study.
    • Pharmacodynamic parameters:
    Pharmacodynamic analysis for TAFIa antigen and clot lysis along with D-dimer and total TAFIa activity will be performed. Remaining blood samples will be used for post-hoc TAFIa inhibition-related coagulation biomarker assessments.
    Recanalization will be assessed during the study.
    • Other parameters:
    An assessment of functional outcome using the mRS will be performed during the study.
