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   43862   clinical trials with a EudraCT protocol, of which   7285   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)
    Average change from baseline (screening and Day 1) in MG-ADL total score over Weeks 22, 23 and 24.
    Variazione media rispetto al basale (screening e Giorno 1) nel punteggio totale MG-ADL durante le Settimane 22, 23 e 24
    E.5.1.1Timepoint(s) of evaluation of this end point
    Throughout the double-blind phase of the study.
    Durante la fase in doppio cieco dello studio
    E.5.2Secondary end point(s)
    1. The average change in the QMG score over Weeks 22 and 24. Analyzed using a similar method (appropriate for the region) as for the primary efficacy endpoint, but since the QMG is not assessed at Week 23, the contrast will average the change from baseline over Weeks 22 and 24 of the double-blind placebo-controlled phase.
    2. Percentage of participants whose average MG-ADL total score over weeks 22, 23 and 24 of the double blind, placebo-controlled phase is at least a 2-point improvement compared to baseline. The average score for a participant is the average of the non-missing values at Weeks 22, 23 and 24. A participant must have a non-missing value at Week 24 and at least 1 non-missing value at Week 22 or 23 in order to have a non-missing average score. A participant with a missing average score will be considered a nonresponder. Analyzed by Cochran-Mantel-Haenszel test controlling for the baseline MG-ADL total score randomization strata (=9, >9), autoantibody status, and region.
    3. Loading dose response, defined for each participant as improvement in the MG-ADL total =2 points at Week 1 and/or Week 2. A participant with a missing assessment at either time point will be considered a nonresponder at that time point. Analyzed by Cochran-Mantel-Haenszel test controlling for the baseline MG-ADL total score randomization strata (=9, >9), autoantibody status, and region.
    4. Symptom remission, defined as the average percentage of participants with MG-ADL score of 0 or 1 over weeks 22, 23 and 24 of the double-blind, placebo-controlled phase. Analyzed with a repeated measures logistic regression model employing a similar contrast as for the primary efficacy analysis.
    5. Sustainability of therapeutic response, defined as the percentage of participants with improvement in MG-ADL total score of = 2 points at Week 2 sustained through Week 24, with no more than 2 excursions allowed at Weeks 3 through 23 (excursions defined as loss of improvement in MG-ADL score of = 2 points). A participant with a missing assessment at a time point will be considered a nonresponder at that time point. Analyzed by Cochran-Mantel-Haenszel test controlling for the baseline MG-ADL total score randomization strata (=9, >9), autoantibody status, and region.
    1. Variazione media nel punteggio QMG durante le Settimane 22 e 24. Analizzata utilizzando un metodo simile (appropriata per la regione) a quello impiegato per l’endpoint di efficacia primario; tuttavia, poiché la scala QMG non viene valutata alla Settimana 23, il contrasto medierà la variazione rispetto al basale durante le Settimane 22 e 24 della fase in doppio cieco controllata con placebo.
    2. Percentuale di partecipanti il cui punteggio MG-ADL medio totale durante le Settimane 22, 23 e 24 della fase in doppio cieco controllata con placebo è un miglioramento di almeno 2 punti rispetto al basale. Il punteggio medio per un partecipante è la media dei valori non mancanti alle Settimane 22, 23 e 24. Un partecipante con un punteggio medio mancante sarà considerato nonresponder. Analizzato mediante il test di Cochran-Mantel-Haenszel che consente il controllo degli strati di randomizzazione del punteggio MG-ADL totale al basale (=9, >9), dello stato autoanticorpale e della regione.
    3. Risposta alla dose di carico, definita per ciascun partecipante come un miglioramento nella scala MG-ADL totale =2 punti alla Settimana 1 e/o alla Settimana 2. Un partecipante con una valutazione mancante in corrispondenza di uno dei due punti temporali sarà considerato nonresponder a quel punto temporale. Questo endpoint sarà analizzato mediante il test di Cochran-Mantel-Haenszel che consente il controllo degli strati di randomizzazione del punteggio MG-ADL totale al basale (=9, >9), dello stato autoanticorpale e della regione.
    4. Remissione dei sintomi, definita come la percentuale media di partecipanti con punteggio MG-ADL pari a 0 o 1 durante le Settimane 22, 23 e 24 della fase in doppio cieco, controllata con placebo. Analizzato con un modello di regressione logistica a misure ripetute che impiega un contrasto simile a quello dell’analisi di efficacia primaria.
    5. Sostenibilità della risposta terapeutica, definita come la percentuale di partecipanti con miglioramento nel punteggio MG-ADL totale =2 punti alla Settimana 2 che si mantiene fino alla Settimana 24, con non più di 2 escursioni consentite alla Settimana 3 fino alla Settimana 23 (escursioni definite come perdita di miglioramento nel punteggio MG-ADL =2 punti). Un partecipante con una valutazione mancante in corrispondenza di un punto temporale sarà considerato non rispondente a quel punto temporale. Analizzato mediante il test di Cochran-Mantel-Haenszel che consente il controllo degli strati di randomizzazione del punteggio MG-ADL totale al basale (=9, >9), dello stato autoanticorpale e della regione.

    F.5 Plans for treatment or care after the subject has ended the participation in the trial (if it is different from the expected normal treatment of that condition)
    Participants who complete the double-blind placebo-controlled phase will continue to the OLE phase where treatment with nipocalimab will continue until 2 years after marketing authorization in a participant’s local country or until nipocalimab becomes available commercially or via other continued access program, whichever comes first. After that no further treatment and medical supervision of the patients after the end of the clinical trial is planned for the above clinical trial.
    I partecipanti che completano la fase di doppio cieco controllata con placebo continueranno con la fase OLE, in cui il trattamento con nipocalimab continuerà fino a 2 anni dopo la immissione in commercio nel paese del partecipante o fino a quando nipocalimab non sarà disponibile in commercio o
    tramite un altro programma di accesso continuato, a seconda di quale delle due condizioni si verifichi per prima. Dopo di che nessun ulteriore trattamento e supervisione medica dei pazienti dopo la .......
