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.

    3. Subjects have symptoms of subarachnoid hemorrhage, even with normal CT.
    4. Subjects have an Alberta Stroke Program Early CT Score (ASPECTS) <6.
    5. Subjects have prior non-traumatic intracranial haemorrhage (excluding microhemorraghes observed in imaging).
    6. Subjects have known arteriovenous malformation or aneurysm.

    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.

Subjects with anticipated use of an anticoagulation dose of heparin, or fondaparinux or low molecular weight heparin, or nonvitamin K antagonist oral anticoagulant such as dabigatran, rivaroxaban, apixaban, or other factor Xa inhibitors within 48 hours after completion of study drug treatment. Low dose heparin or low molecular weight heparin at a preventive dose are allowed from 24 hours after treatment completion and after confirmation of no intracranial bleeding on the 24 hours repeat brain imaging. In Cohort 6, heparin treatment associated with IAT is allowed.
    14. Subjects have blood pressure > 185/110 mmHg, or require aggressive medication to maintain blood pressure below this limit (routine medical treatment is allowed to lower the blood pressure below this limit).
    15. Subjects have had intracranial surgery, clinically significant head trauma (in the opinion of Principal Investigator), Alteplase treatment, or a previous stroke within 1 months.
    16. Subjects have had major surgery within 14 days.

    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.
    Exploratory Parameter:
    For subjects treated with IAT, the retrieved clots will be collected (when possible) for exploratory histopathology assessment on clot formation and dissolution, and analyses on thrombosis and thrombolysis related biomarkers. A blood sample from the location
    proximal to the thrombus will be collected via the thrombectomy catheter (when possible) for exploratory biomarker evaluation (TAFI and/or TAFIa levels).
