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   43845   clinical trials with a EudraCT protocol, of which   7282   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 ).

    E.5 End points
    E.5.1Primary end point(s)
    Proportion of subjects who achieve long-term response (6 months sustained response) and able to taper down the dose. A patient will achieve this endpoint if at the end of the period of treatment he/she reaches to discontinue Eltrombopag and if, after discontinuation, has absence of bleeding and maintains a platelet count ≥ 30 x 109/L and at least a 2-fold increase from the baseline count in blood cell count performed in the 6 months of the period observation, during which no steroid, Eltrombopag, other anti TPO-R agonists and other anti-ITP medications are administered.
    Percentuale di soggetti che raggiungono la risposta a lungo termine (6 mesi di risposta sostenuta ) e in grado di ridurre gradualmente la dose. Un paziente raggiungerà questo endpoint se alla fine del periodo di trattamento interrompe Eltrombopag e se , dopo la sospensione, ha assenza di sanguinamento e mantiene la conta piastrinica ≥ 30 x 109 / L e aumenta almeno di 2 volte la conta al baseline delle cellule del sangue effettuata nei 6 mesi del periodo di osservazione, durante il quale non vengono somministrati steroidi, eltrombopag, altri agonisti TPO - R e altri farmaci anti- anti- ITP.

    a) i livelli sierici di citochine (IL-1, IL-8, TNFa, IL-6, IL-4, IL-10, IL-17, IL-22, IFNγ, osteopontina);
    e) b) sottopopolazioni linfocitarie: B (CD19+), marginal zone B (CD19+ CD27+ IgD+), switching memory B (CD19+ CD27+ IgD+), T (CD3+), T helper (CD4+) T cytotoxic (CD8+), Th effector memory (CD4+CD45R0+CCR7-), Th central memory (CD4+ CD45R0+ CCR7+) and Th naïve (CD4+ CD45RA+), T cytotoxic memory and naïve (CD45RA+/R0+), effector T cytotoxic (CD8+ perforin+), regulatory T cells (CD4+ CD25+Foxp3+), Tgamma/delta (TCRγδ+), NK (CD16+ CD56+), NKT (TCRαv24+ β11+), myeloid dendritic cells (HLA-DR+ CD11c+), plasmacytoid dendritic cells (Lin-HLA-DR+ CD123+).

    c) la produzione di citochine da parte delle cellule T ex vivo (ELISA e colorazione intracitoplasmatica): IL-4 (le cellule TH2), IFNγ (TH1), IL-17 (TH17), IL-10 (Treg), IL-9 (TH9), IL-22 (Th22)
    d) la produzione di citochine da parte delle cellule dendritiche mieloidi (colorazione intracitoplasmatica): IL-10, IL-12.
    4. Relazione tra livelli sierici basali TPO e la risposta alla terapia: TPO sarà misurata con un test TPO umano duo-set (R & S System). Questo test utilizza la tecnica enzimatica quantitativa a sandwich immunoassay per valutare la concentrazione di TPO nel plasma o nel siero
