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   43839   clinical trials with a EudraCT protocol, of which   7280   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.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives

    Other types of substudies
    Specify title, date and version of each substudy with relative objectives: Merck will conduct Future Biomedical Research on DNA (Blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is
    to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time.

    Moreover Merck will conduct un optional Sub study on Stool Samples for Microbiome analysis.

    Altre tipologie di sottostudi
    specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: Merck condurrà una Ricerca Biomedica Futura su campioni di DNA (sangue) raccolti nel corso di questo studio clinico. Tale ricerca ha lo scopo di esaminare vari biomarcatori per rispondere a domande che stanno emergendo e che non sono descritte in altre parti del protocollo (nell’ambito dello studio principale), e verrà condotta solo su campioni di soggetti che abbiano rilasciato apposito consenso. L'obiettivo della raccolta dei campioni per la Ricerca Biomedica Futura è quello di esplorare e identificare biomarcatori che contribuiscano scientificamente alla comprensione delle malattie e/o della relative terapie. L'obiettivo ultimo è quello di utilizzare tali informazioni per sviluppare farmaci più sicuri e più efficaci, e/o per garantire che i soggetti ricevano la dose giusta del giusto farmaco al momento giusto.

    Inoltre Merck condurrà un sottostudio opzionale sulla raccolta di campioni di feci per l’analisi del microbioma.

    6. Anamnesi di polmonite (non infettiva) che ha richiesto l’uso di steroidi oppure polmonite in corso.
    7. Presenta un’infezione attiva con necessità di terapia sistemica.
    8. Presenta doppia infezione attiva da HBV (HBsAg [+] e/o DNA di HBV rilevabile) e infezione da HCV (anticorpi anti-HCV [+] e RNA di HCV rilevabile) al momento dell’ingresso nello studio.
    9. Anamnesi nota di infezione da virus dell’immunodeficienza umana (HIV). Non è richiesto alcun test per l’HIV salvo se prescritto dall’autorità sanitaria locale. Fare riferimento all’Appendice 7 (vedere protocollo) per i requisiti nazionali specifici.
    10. Presenta tubercolosi (TBC; Bacillus tuberculosis) nota attiva.
    11. Ha ricevuto una terapia precedente con un agente anti-PD-1, anti-PD-L1 o anti-PD-L2 o con un agente diretto contro un altro recettore stimolante o co-inibitorio delle cellule T (ad es. CTLA-4, OX-40, CD137).
    12. Precedente terapia antitumorale sistemica per HCC, inclusi agenti sperimentali.
    13. Sta ricevendo una qualsiasi delle seguenti terapie concomitanti vietate (vedere Sezione 6.5 del protocollo):
    • Chemioterapia sistemica antineoplastica o terapia biologica
    • Immunoterapia non specificata in questo protocollo
    • Agenti sperimentali diversi da pembrolizumab
    • Radioterapia
    • Terapia oncologica chirurgica
    • Glucocorticoidi sistemici per qualsiasi scopo diverso dalla modulazione dei sintomi derivanti da un EA di sospetta eziologia immunologica. Sono consentiti gli steroidi per inalazione o per uso topico e gli steroidi sistemici a dosi =10 mg/giorno di prednisone o equivalente. Eccezione: gli steroidi possono essere usati per la premedicazione prima della diagnostica per immagini.
    14. Ricezione di un vaccino vivo nei 30 giorni precedenti la prima dose del trattamento dello studio. Esempi di vaccini vivi comprendono, a titolo esemplificativo: morbillo, parotite, rosolia, varicella/zoster, febbre gialla, rabbia, bacillo di Calmette-Guérin (BCG) e vaccino tifoideo. I vaccini per l’influenza stagionale somministrati per iniezione in genere sono vaccini con virus inattivati e sono ammessi; tuttavia i vaccini antinfluenzali intranasali (ad es. Flu-Mist®, [vaccino antinfluenzale vivo, AstraZeneca]) sono vaccini vivi attenuati e non sono consentiti.
    15. Sta partecipando o ha partecipato a uno studio condotto su un agente sperimentale o sta utilizzando un dispositivo sperimentale nelle 4 settimane precedenti il C1G1.
