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   44241   clinical trials with a EudraCT protocol, of which   7338   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)
    The specific aims of our study are:
    1. To investigate the effects of single dosis of 50 mg of sildenafil and the additive effect of inhaled NO, on cardiac hemodynamics, RV contractility and blood cGMP concentrations. We aim to establish whether the response of patients to sildenafil would be different depending on the degree of RV failure, RV or LV hypertrophy or fibrosis
    2. To investigate the evolution of LV and RV strain and function, as well as pulmonary pressures and pulmonary resistance during bicycle exercise echocardiography
    3. To investigate degree of fibrosis by circulating fibrosis markers and cardiac MRI imaging for diffuse fibrosis

    In the subgroup of HTX patients presenting with HFpEF physiology specific additional aims are:

    4. To investigate on myocardial biopsy from the right ventricle the PDE5 expression and relate it to effects of oral sildenafil
    5. To analyze the presence of circulating blood markers of fibrosis and to correlate them with presence of fibrosis as assessed by cardiac MRI and myocardial biopsies from RV
    6. to perform an unbiased discovery of molecular pathways contributing to HFpEF physiology and PH using high throughput mRNA and microRNA expression analysis of right ventricular biopsy specimens
    E.5.1.1Timepoint(s) of evaluation of this end point
    Hemodynamic measurements, pressure volume loops of the right ventricle and blood cGMP concentration during three stages: at baseline, 30 minutes after 50 mg sildenafil administration and 15 minutes after NO inhalation (80 ppm).
    E.5.2Secondary end point(s)
    Correlation of hemodynamic response with:
    - Presence of fibrosis in right and left ventricle as assessed by MRI, circulating fibrosis biomarkers and expression of PDE5 in myocardium
    - Exercise capacity
    - Long function
    E.5.2.1Timepoint(s) of evaluation of this end point
    The blood sample for marker of fibrosis will be taken and stored for future analysis, when we could obtain the funding for it.
