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   43206   clinical trials with a EudraCT protocol, of which   7151   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    • Changes from baseline in blood pressure over time

    Efficacy Endpoints:
    • Durable hemoglobin response (Yes/No) within 24 weeks of treatment
    A hemoglobin response is defined as a hemoglobin level of >10 g/dL and =2 g/dL higher than the baseline (i.e, hemoglobin value prior to fostamatinib exposure), during the previous 4 weeks, the steroid dose is not higher than the baseline level, and rescue medication is not administered. A durable response is defined as a hemoglobin response on at least 3 scheduled visits during the first 24 weeks of this study.
    • Hemoglobin response at 48 weeks (Yes/No) defined as subjects who achieve a durable response, as above, and have a hemoglobin response at 48 weeks
    • Hemoglobin response by week 24
    • Partial hemoglobin response, defined as a Hgb change from baseline of =2 g/dL

    • Subjects who decrease any concomitant wAIHA therapy
    Endpoint di sicurezza:
    • Eventi avversi

    • Variazioni rispetto alla baseline della pressione sanguigna nel tempo
    Endpoint di efficacia:
    • Risposta duratura dell'emoglobina (Si/No) entro 24 settimane dal trattamento
    Una risposta dell'emoglobina è definita come un livello di emoglobina di >10 g/dL e = 2 g/dL più elevato rispetto alla baseline (ossia il valore dell’emoglobina prima dell’esposizione a fostamatinib), durante le 4 settimane precedenti, la dose di steroidi non è superiore rispetto al livello basale e non sono stati somministrati farmaci di salvataggio.
    Una risposta duratura è definita come una risposta dell'emoglobina in almeno 3 visite programmate durante le prime 24 settimane di questo studio.
    • Risposta dell'emoglobina a 48 settimane (Sì/No) definita come soggetti che ottengono una risposta duratura, come sopra, e hanno una risposta dell’emoglobina a 48 settimane
    • Risposta dell'emoglobina entro la settimana 24
    • Risposta parziale dell'emoglobina, definita come una variazione dell’Hgb rispetto alla baseline di =2 g/dL
    • Soggetti che raggiungono una dose di steroidi < 10 mg/die (equivalente del prednisone)
    • Variazione rispetto alla baseline dei valori di emoglobina nel tempo
    • Variazione rispetto alla baseline della dose di steroidi
    • Soggetti che necessitano di eventuale salvataggio durante questo studio
    • Durata complessiva della risposta e durata della prima risposta
    • Soggetti che riducono qualsiasi terapia concomitante per la wAIHA
