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   38927   clinical trials with a EudraCT protocol, of which   6396   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
    To study whether the mineralocorticoid receptor antagonist eplerenone activates CD73 and hereby increases extracellular formation of adenosine in humans in vivo, by using the forearm vasodilator respons to the intrabrachial administration of the ENT-inhibitor dipyridamole, as a surrogate for adenosine stimulation
    Het belangrijkste doel is te onderzoeken of de mineralocorticoid receptorantagonist eplerenon CD73 activeert en hierdoor zorgt voor een toename van de extracellulaire vorming van adenosine bij gezonde vrijwilligers. Om dit te onderzoeken wordt de respons van dipyridamol op de bloeddoorstroming in de onderarm gebruikt. Dipyridamol dient als een surrogaat voor adenosevorming.
    E.2.2Secondary objectives of the trial
    The effect of eplerenone on the forearm vasodilator response to arterial occlusion (post occlusive reactive hyperemia)
    Het verschil in bloeddoorstroming in de onderarm na arteriële occlusie (post occlusive reactive hyperemia) tussen eplerenon en placebo

    E.4Principal exclusion criteria
    potassium >4.8 mmol/L, smoking, hypertension (SBP >140 or DBP >90 mmHg), hypotension (SBP <100 or DBP <60 mmHg), diabetes mellitus (fasting glucose >7.0 mmol/L or random >11.0 mmol/L), history of any cardiovascular disease, angina pectoris, history of COPD or asthma, alcohol and/or drug abuse, concomitant use of medication, renal dysfunction (MDRD <60 mL/min), liver enzyme abnormalities (ALAT >twice upper limit), fasting total cholesterol >6 mmol/L, 2nd/3rd degree AV block on electrocardiography. During the study a serum potassium of >5.2 mmol/L is an exclusion criterium.
    serum kalium >4.8 mmol/L, roken, hypertensie (SBP >140 of DBP >90 mmHg), hypotensie (SBP <100 of DBP <60 mmHg), diabetes mellitus (nuchter glucose >7.0 mmol/L of random >11.0 mmol/L), voorgeschiedenis met cardiovasculaire aandoeningen, angina pectoris, COPD of astma (in voorgeschiedenis), alcohol en/of drugsmisbruik, gebruik van medicatie, nierfunctiestoornis (MDRD <60 mL/min), leverenzymstoornis (ALAT meer dan 2x verhoogd), nuchter cholesterol >6 mmol/L, 2e of 3e graads AV block op ECG. Tijdens de studie worden personen met een serum kalium >5.2 mmol/L uit de studie geëxcludeerd.
    E.5 End points
    E.5.1Primary end point(s)
    forearm blood flow (measured with venous plethysmography). The forearm blood flow respons will be measured during usage of eplerenone and during usage of placebo to:
    1) administration of incremental dosages of dipyridamole into the brachial artery (as a surrogate for adenosine formation)
    2) 2 and 5 minutes of arterial occlusion (post occlusive reactive hyperemia), because this is known to stimulate adenosine formation
    3) co-administration of dipyridamole and caffeine. Dipyridamole increases adenosine formation and this effect is blocked by caffeine.
    4) two different concentrations of adenosine and sodium-nitroprusside. These substances serve as negative control and exclude non-specific effects of eplerenone on vascular reactivity or adenosine sensitivity.
    De bloeddoorstroming in de onderarm wordt met behulp van veneuze plethysmografie gemeten. Experimenten worden tijdens het gebruik van eplerenon en tijdens het gebruik van placebo gedaan en verschil in bloeddoorstroming wordt gemeten in respons op:
    1) verschillende doseringen dipyridamol. Dipyridamol remt de ENT en verhoogt hiermee het extracellulaire gevormde adenosine.
    2) 2 verschillende perioden van arteriële occlusie (2 en 5 min). Het is bekend dat hiermee de adenosinevorming wordt gestimuleerd.
    3) co-administratie van caffeïne. De verhoging van extracellulair adenosine t.g.v. dipyridamol wordt door caffeïne geblokkeerd.
    4) 2 verschillende concentraties van adenosine en sodium-nitroprusside om non-specifieke effecten van eplerenon op de vasculaire reactiviteit en adenosine gevoeligheid uit te sluiten.
    E.5.1.1Timepoint(s) of evaluation of this end point
    7 days after start of eplerenone or placebo, the experiments will be performed. Because not all experiments can be done on the same day, forearm blood flow response to adenosine and sodium-nitroprusside will be performed 8 days after start of eplerenone.
    7 dagen nadat gestart is met eplerenon of de placebo wordt de veneuze plethysmografie uitgevoerd en wordt gekeken naar het effect op de bloeddoorstroming van deze middelen. Omdat niet alle experimenten of 1 dag kunnen worden voltooid, wordt een dag later de bloeddoorstroming met co-administratie van adenosine en natrium-nitroprusside gemeten.
