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   43873   clinical trials with a EudraCT protocol, of which   7292   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.

    Title: A RANDOMIZED, OPEN-LABEL ECULIZUMAB AND RAVULIZUMAB CONTROLLED STUDY TO EVALUATE THE EFFICACY AND SAFETY OF POZELIMAB AND CEMDISIRAN COMBINATION THERAPY IN PATIENTS WITH PAROXYSMAL NOCTURNAL HEMOGLOBINURIA WHO ARE CURRENTLY TREATED WITH ECULIZUMAB OR RAVULIZUMAB
    Objectives: Future Biomedical Research (Optional): Patients who agree to participate in the future biomedical research (FBR) sub-study will be required to consent to this optional sub-study before samples are banked for FBR. Residual biomarker samples for study-related research, as well as unused PK and ADA samples, will be stored for up to 15 years after the final date of the database lock (or for a shorter time period if required per regional laws and regulations). The samples may be utilized for FBR that may or may not be directly related to the study, including being used as reference samples and assay development or validation. Pharmacogenomic Analysis (Optional): Patients who agree to participate in the genomics sub-study will be required to consent to this optional sub-study before collection of the samples. Whole blood samples for DNA extraction should be collected on day 1/baseline (predose), but can be collected at a later study visit. Whole blood samples for RNA extraction will be collected at time points according to Table 1. DNA and RNA samples will be collected for pharmacogenomics analyses to understand the genetic determinants of efficacy and safety associated with the treatments in this study and the molecular basis of PNH and related diseases. These samples will be single-coded as defined by the International Council on Harmonisation (ICH) guideline E15. Samples will be stored for up to 15 years after the final date of the database lock (or for a shorter time period if required per regional laws and regulations). If there are specific site or country requirements involving the pharmacogenomic analyses which the sponsor is unable to comply with, samples will not be collected at those sites. The purpose of the pharmacogenomic analyses is to identify genomic associations with clinical or biomarker response to pozelimab and cemdisiran, other PNH clinical outcome measures and possible AEs. In addition, associations between genomic variants and prognosis or progression of PNH as well as related diseases may also be studied. These data may be used or combined with data collected from other studies to identify and validate genomic markers related to the study drug, target pathway, or PNH and related diseases. Analyses may include sequence determination or single nucleotide polymorphism studies of candidate genes and surrounding genomic regions. Other methods, including whole-exome sequencing, whole genome sequencing, DNA copy number variation, and transcriptome sequencing (or other methods for quantitating RNA expression) may also be performed. The list of methods may be expanded to include novel methodology that may be developed during the course of this study or sample storage period.

    Titolo: STUDIO CONTROLLATO RANDOMIZZATO, IN APERTO, SU ECULIZUMAB E RAVULIZUMAB VOLTO A VALUTARE L'EFFICACIA E LA SICUREZZA DELLA TERAPIA DI COMBINAZIONE CON POZELIMAB E CEMDISIRAN IN PAZIENTI AFFETTI DA EMOGLOBINURIA PAROSSISTICA NOTTURNA ATTUALMENTE TRATTATI CON ECULIZUMAB O RAVULIZUMAB
    Obiettivi: Ricerca biomedica futura (Future Biomedical Research, FBR) (opzionale): I pazienti che accettano di partecipare al sottostudio di ricerca biomedica futura (FBR) dovranno acconsentire a questo sottostudio facoltativo prima che i campioni vengano archiviati per FBR. I campioni residui di biomarcatori per la ricerca correlata allo studio, così come i campioni PK e ADA inutilizzati, saranno conservati per un massimo di 15 anni dopo la data finale del database lock (o per un periodo di tempo più breve se richiesto dalle leggi e dai regolamenti locali). I campioni possono essere utilizzati per FBR che possono o non possono essere direttamente correlati allo studio, compreso l'uso come campioni di riferimento e lo sviluppo o la convalida del test. Analisi farmacogenomica (opzionale): I pazienti che accettano di partecipare al sottostudio di genomica dovranno acconsentire a questo sottostudio facoltativo prima del prelievo dei campioni. I campioni di sangue intero per l'estrazione del DNA devono essere raccolti il giorno 1/basale (predose), ma possono essere raccolti in una visita di studio successiva. Saranno raccolti campioni di sangue intero per l'estrazione dell'RNA in punti temporali secondo la Tabella 1. Saranno raccolti campioni di DNA e RNA per analisi farmacogenomiche per comprendere i determinanti genetici di efficacia e sicurezza associati ai trattamenti in questo studio e le basi molecolari di EPN e malattie correlate. Questi campioni saranno a codice singolo come definito dalla linea guida E15 della Conferenza internazionale per l'armonizzazione (ICH). I campioni verranno conservati per un massimo di 15 anni dopo la data finale del database lock (o per un periodo di tempo più breve se richiesto dalle leggi e dai regolamenti locali). Se ci sono requisiti specifici del centro o del paese che coinvolgono le analisi farmacogenomiche che lo sponsor non è in grado di rispettare, i campioni non verranno raccolti in quei centri. Lo scopo delle analisi farmacogenomiche è di identificare le associazioni genomiche con la risposta clinica o di biomarcatori a pozelimab e cemdisiran, altre misure di esito clinico della EPN e possibili eventi avversi. Inoltre, possono essere studiate anche le associazioni tra varianti genomiche e prognosi o progressione della EPN, nonché malattie correlate. Questi dati possono essere utilizzati o combinati con i dati raccolti da altri studi per identificare e convalidare i marcatori genomici correlati al farmaco in studio, alla via bersaglio o all'EPN e malattie correlate. Le analisi possono includere la determinazione della sequenza o studi sul polimorfismo a singolo nucleotide dei geni candidati e delle regioni genomiche circostanti. Possono essere eseguiti anche altri metodi, tra cui il sequenziamento dell'intero esoma, il sequenziamento dell'intero genoma, la variazione del numero di copie del DNA e il sequenziamento del trascrittoma (o altri metodi per quantificare l'espressione dell'RNA). L'elenco dei metodi può essere ampliato per includere una nuova metodologia che può essere sviluppata nel corso di questo studio o nel periodo di conservazione del campione.

    Patients who complete the OLTP will be offered the opportunity to enroll in another study, a follow-on OLE study. For patients who complete the 36-week OLTP on the pozelimab and cemdisiran arm, the transition of treatment from the current study to the OLE is planned to be uninterrupted. Patients who complete the 36-week OLTP on the anti-C5 standard-of-care arm will undergo a transition period in order to switch to cemdisiran and pozelimab combination treatment
    Ai pazienti che completano l'OLTP verrà offerta l'opportunità di iscriversi a un altro studio, uno studio OLE di follow-up. Per i pazienti che completano l'OLTP di 36 settimane nel braccio pozelimab e cemdisiran, la transizione del trattamento dallo studio attuale all'OLE dovrebbe essere ininterrotta. I pazienti che completano l'OLTP di 36 settimane nel braccio standard di cura anti-C5 subiranno un periodo di transizione per passare al trattamento combinato con cemdisiran e pozelimab
