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   43861   clinical trials with a EudraCT protocol, of which   7284   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.

    Subjects may be on a stable dose of either a PDE5-I or a sGC stimulator, not both.
    a) If the subject's disease-specific PAH therapy does not include a PDE5-I, the use of PDE5-I as needed for erectile dysfunction (ED), up to 3 doses per week, is permitted. The subject should not have taken a dose within 48 hours of Baseline.

    c) Resistenza vascolare polmonare (RVP) =3 unità Wood o =240 dyne/sec/cm5
    Qualora sia stata eseguita più di 1 RHC entro 1 anno dallo screening, per questa valutazione deve essere usata la RHC più recente che comprenda parametri sufficienti per valutare i suddetti criteri.

I soggetti possono assumere una dose stabile di un PDE5-I o uno stimolatore della sGC, ma non entrambi.
    a) Se la terapia per IAP specifica per la malattia del soggetto non include un PDE5-I, è consentito l’uso di PDE5-I, se necessario, in caso di disfunzione erettile (DE) fino a 3 dosi a settimana. Il soggetto non deve avere assunto una dose entro 48 ore dalla visita basale.
    7) Il soggetto presenta una distanza percorsa camminando per 6 minuti (6MWD) =150 metri durante lo screening.

L’eccezione è che la dose dei diuretici deve rimanere stabile per almeno 10 giorni prima del basale.
    11) I soggetti ambosessi devono acconsentire all’uso di un metodo di controllo delle nascite altamente efficace per tutta la durata dell’intero periodo di studio, dal consenso informato fino alla visita della Settimana 28/visita di follow-up a 28 giorni, qualora sussista il rischio di concepimento.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint of the study is the change from Baseline in peak VO2 after 28 weeks of treatment with study drug.

    Through the study.
    Per tutto lo studio.
    E.5.2Secondary end point(s)
    The following secondary endpoints will be analyzed in hierarchical order:
    • Change from Baseline at Week 28 in NT-proBNP: NT-proBNP with log transformation will be analyzed in the ITT population using mixed-effect model repeated measures (MMRM) analysis with treatment, the stratification factors, week, and treatment-by-week interaction as factors and baseline NT-proBNP as a covariate
    • Change from Baseline at Week 28 in VE/VCO2 slope: VE/VCO2 slope will be analyzed in the mITT population and repeated in the ITT population using ANCOVA with a model that includes treatment and the stratification factors as factors and Baseline VE/VCO2 slope as a covariate.
    • Change in SF-36 scores from Baseline to Week 28: the component and domain scores will be analyzed in the ITT population using MMRM analysis with treatment, the stratification factors, week, and treatmentby-week interaction as factors and baseline component/domain score as a covariate.
    • Time to first all-cause nonelective hospitalization in randomized subjects during the study period will be analyzed in the ITT population using Cox proportional hazard regression model that includes treatment and the stratification factors.; I seguenti endpoint secondari verranno analizzati in ordine gerarchico:
    • Modifica rispetto al basale alla settimana 28 nel NT-proBNP: NT-proBNP con log transformation sarà analizzata nella popolazione ITT usando un modello misto per misure ripetute (MMRM) con trattamento, il fattori di stratificazione, settimana e interazione trattamento per settimana come fattori e NT-proBNP basele come covariata
    • Modifica dal basale alla settimana 28 della pendenza VE / VCO2: pendenza VE / VCO sarà analizzato nella popolazione mITT e ripetuto nella popolazione ITT che utilizza ANCOVA con un modello che include il trattamento e i fattori di stratificazione come fattori e la pendenza VE / VCO2 basale come covariata.
    • Modifica dei punteggi SF-36 dal basale alla settimana 28: il componente e i punteggi di dominio saranno analizzati nella popolazione ITT usando MMRM con trattamento, fattori di stratificazione, settimana e l'interazione trattamento per settimana, come fattori e punteggio del componente / dominio di base come covariata.
    • Momento del primo ricovero non elettivo per qualsiasi causa per i soggetti randomizzati durante il periodo di studio sarà analizzato nella popolazione ITT utilizzando il modello di regressione proporzionale del rischio Cox che include il trattamento e i fattori di stratificazione.
