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   43871   clinical trials with a EudraCT protocol, of which   7290   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, RAVULIZUMAB-CONTROLLED STUDY TO EVALUATE THE EFFICACY AND SAFETY OF POZELIMAB AND CEMDISIRAN COMBINATION THERAPY IN PATIENTS WITH PAROXYSMAL NOCTURNAL HEMOGLOBINURIA WHO ARE COMPLEMENT INHIBITOR TREATMENT-NAIVE OR HAVE NOT RECENTLY RECEIVED COMPLEMENT INHIBITOR THERAPY
    Objectives: 1. Future Biomedical Research (FBR) (Optional): 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. 2. Pharmacogenomic Analysis (Optional): 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 of protocol. 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. 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 RANDOMIZZATO, IN APERTO, CONTROLLATO CON RAVULIZUMAB VOLTO A VALUTARE L'EFFICACIA E LA SICUREZZA DELLA TERAPIA DI COMBINAZIONE CON POZELIMAB E CEMDISIRAN IN PAZIENTI AFFETTI DA EMOGLOBINURIA PAROSSISTICA NOTTURNA NAIVE AL TRATTAMENTO CON INIBITORI DEL COMPLEMENTO O CHE NON HANNO RECENTEMENTE RICEVUTO TERAPIA CON INIBITORI DEL COMPLEMENTO
    Obiettivi: 1. Ricerca biomedica futura (Future Biomedical Research, FBR) (opzionale): Campioni residui di biomarcatori per la ricerca correlata allo studio, nonché campioni PK e ADA non utilizzati verranno conservati per un massimo di 15 anni dopo la data finale del database lock (o per un periodo di tempo più breve se previsto 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. 2. Analisi farmacogenomica (opzionale): 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. I campioni di sangue intero per l'estrazione dell'RNA saranno raccolti in punti temporali secondo la Tabella 1 del protocollo. Saranno raccolti campioni di DNA e RNA per analisi farmacogenomiche per comprendere i determinanti genetici dell'efficacia e della sicurezza associati ai trattamenti in questo studio e le basi molecolari della EPN e delle malattie correlate. Lo scopo delle analisi farmacogenomiche è 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.
