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   37227   clinical trials with a EudraCT protocol, of which   6125   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
    The main objective is to investigate the effect of the phosphodiesterase-5-inhibitor (PDE-5-inhibitor) tadalafil on blood flow velocity in the brain's large arteries and cortical brain oxygenation in patients with former lacunar strokes caused by small vessel diseases.
    Formålet med forsøget er at undersøge phosphodiesterase-5-hæmmeren (PDE-5-hæmmeren) tadalafils virkning på blodgennemstrømningen i hjernens store arterier samt kortikal iltmætning i hjernen hos patienter som tidligere har haft små blodpropper i hjernen forårsaget af småkarssygdomme.
    E.2.2Secondary objectives of the trial
    Secundary objectives is to investigate if tadalafil improves the peripheral endothelial function measured as an improved blood vessel respons in the fingers after a short occlusion of blood suply to the arm measured with EndoPAT2000.
    Besides that there will be a change in endothelial function markers in the blood after a single dosis of tadalafil and that these changes correspond to the measured peripheral or central blood vessel function.
    Feasibility of applying tadalafil in stroke patients.
    Sekundære formål er at undersøge om tadalafil forbedrer den perifere endothelfunktion målt som forbedret blodkarrespons i fingrene efter kortvarig afklemning af blodforsyningen til armen målt med EndoPAT2000.
    Derudover at der sker en ændring af endothelfunktionsmarkører i blodet efter en enkelt dosis tadalafil og at disse ændringer svarer til den målte perifere eller centrale blodkarsfunktion.
    Praktisk mulighed for at bruge tadalafil hos apopleksipatienter.
