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   43857   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.

    E.5 End points
    E.5.1Primary end point(s)
    Potential recommended dose (PRD) and actual recommended dose(RD).
    Determinare la dose potenziale raccomandata(DPR)e la dose effettiva raccomandata(DR)di sotatercept
    E.5.1.1Timepoint(s) of evaluation of this end point
    The recomended dose will be evaluated following the last subject of the confirmation cohort, including the last subject who received the last dose.
    The potential recomended dose will be evaluated for each dose level/subject cohort (n=6) after the last patient received the third dose.
    La dose raccomandata sarà determinata quando l'ultimo paziente arruolato nella coorte che ha definito il livello di dose, avrà ricevuto l'ultima somministrazione di farmaco.
    La dose potenziale raccomandata sarà determinata per ciascun livello di dose/coorte di soggetti (n.6) dopo che l'ultimo paziente avrà ricevuto la terza somministrazione di farmaco.
    E.5.2Secondary end point(s)
    RBC transfusion burden reduction in transfusion dependent β-thalassemia major and β-thalassemia intermedia subjects.
    •Hgb level increase during the study treatment compared to the baseline Hgb level in non-transfusion dependent -thalassemia intermedia subjects.
    •Safety (type, frequency, and severity of adverse events and relationship to sotatercept [according to the currently active minor version of National Cancer Institute (NCI) Common Terminology for Adverse Events (CTCAE) version 4.0]).
    •Concentrations of sotatercept in serum.
    •Concentration of anti–sotatercept antibody
    •Valutare la riduzione del carico trasfusionale di globuli rossi in soggetti affetti da β-talassemia major e β-talassemia intermedia trasfusione-dipendenti.
    •Esaminare l’innalzamento dei livelli di Hgb nel corso del trattamento con il farmaco in studio rispetto ai livelli basali in soggetti affetti da β-talassemia intermedia non-trasfusione dipendente.
    •Determinare il profilo di sicurezza (tipo, frequenza e gravità degli eventi avversi e relazione con sotatercept [secondo i criteri CTCAE (Criteri comuni di terminologia per gli eventi avversi), versione 4.0, del National Cancer Institute (NCI]).
    •Determinare le concentrazioni sieriche di sotatercept.
    •Determinare le concentrazioni anticorpali di anti-sotatercept.
    E.5.2.1Timepoint(s) of evaluation of this end point
    RBC transfusion burden redaction will be assesset at every visit; Hg level increase will be assessed at every visit, safety will be assessed continuously and three weeks after the last dose and at study discontinuation; concentration of sotatercept in serum will be assessed weekly at first cycle; at day 1 and 8 of cycle 2 and 3 and every first visit for the following cycles; concentration of anti-sotatercept antibodies will be assessed at every first visit of each cycle, once during the follo-up period and four months afer the last dose
    La riduzione del carico trasfusionale sarà valutata a ogni visita; L'incremento del valore di Hgb sarà valutato a ogni visita; Il profilo di sicurezza sarà valutato continuamente fino a tre settimane dopo l'ultima somministrazione di farmaco e alla visita di fine studio; la concentrazione sierica di sotatercept sarà valutata settimanalmente al primo ciclo, nei giorni 1 e 8 al secondo e terzo ciclo, e al giorno 1 di ogni ciclo successivo; La concentrazione degli anticopri anti-sotatercept sarà valutata al giorno 1 di ogni ciclo una volta durante il periodo di Follow-up e quattro mesi dopo l'ultima somministrazione di farmaco.
