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   43870   clinical trials with a EudraCT protocol, of which   7289   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)
    Efficacy
    PFS based on independent radiologic review using modified RECIST (mRECIST) (Appendix 17.1). mRECIST criteria includes:
    • No lymph nodes chosen as target lesions; enlarged lymph nodes followed as non-target lesions;
    • No bone lesions chosen as target lesions;
    • PET not acceptable for radiological evaluation;
    • A progressively growing new tumor nodule within a pre-existing tumor mass must meet the following
    criteria to be considered as unequivocal evidence of progression according to the modification of RECIST
    Version 1.1: (a) the lesion is at least 2 cm in size and definitively a new active GIST lesion (e.g. enhancing
    with contrast or other criteria to rule out artefact); or (b) the lesion has to be expanding on at least 2
    sequential imaging studies.
    Efficacia
    PFS di DCC-2618 sulla base di una revisione radiologica indipendente mediante i criteri mRECIST(Appendix
    17.1). I criteri mRECIST comprendono:
    • Assenza di linfonodi scelti come lesioni target; linfonodi ingrossati seguiti come lesioni non target;
    • Assenza di lesioni ossee scelte come lesioni target;
    • Tomografia a emissione di positroni (PET) non accettabile per la valutazione radiologica;
    • Un nuovo nodulo tumorale progressivamente crescente all’interno di una massa tumorale preesistente
    deve soddisfare i seguenti criteri per essere considerato un’evidenza di progressione inequivocabile in
    base ai criteri RECIST modificati, Versione 1.1: (a) la lesione ha una dimensione di almeno 2 cm ed è
    effettivamente una nuova lesione GIST attiva (ad es.: aumentando il mezzo di contrasto o altri criteri
    per escludere l’artefatto); o (b) la lesione deve essere in espansione in almeno 2 studi sequenziali di
    diagnostica per immagini.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary endpoint of PFS (reported in weeks) is defined as the interval between the date of randomization and the earliest documented evidence of disease progression based on the independent radiologic
    review, or death due to any cause. Patients who undergo surgical resection of target or non-target lesions, who have received other anticancer treatments, or patients who do not have a documented date
    of progression or death due to any cause will be censored at the date of the last assessment.
    L’endpoint primario della sopravvivenza libera da progressione (PFS) (riportata in settimane) è definito dall’intervallo tra la data di randomizzazione e la prima evidenza documentata di progressione della malattia, sulla base della revisione radiologica indipendente, o il decesso per qualsiasi causa. I pazienti sottoposti a resezione chirurgica di lesioni target o non target, che hanno ricevuto altri trattamenti antitumorali o per i quali non è disponibile una data documentata di progressione o decesso per qualsiasi causa, saranno censurati alla data dell’ultima valutazione.
    E.5.2Secondary end point(s)
    Efficacy
    • ORR (confirmed CR + confirmed PR) based on independent radiologic review using mRECIST
    criteria
    • OS
    The primary and secondary endpoints will be analyzed for both the KIT Exon 11 (Exon 11 ITT) and the All Patient (AP ITT) population.
    Safety
    Safety endpoints that will be evaluated include treatment-emergent adverse events (TEAEs), AESIs, SAEs, dose reduction or discontinuation of study drug due to toxicity; and changes from baseline in ECOG PS, vital signs, ECGs, LVEF, dermatologic examinations, and clinical laboratory parameters.
    Pharmacokinetics
    • Correlation of PK exposure with efficacy/safety
    • Population-based PK parameters
    Efficacia
    • ORR (risposta completa confermata [CR] + risposta parziale [PR]) sulla base della revisione
    radiologica indipendente mediante i criteri mRECIST
    • OS
    Gli endpoint primario e secondario saranno analizzati sia per la popolazione KIT Exon 11 (Exon 11 ITT) sia per la popolazione All Patient (AP ITT).
    Sicurezza:
    Eventi avversi emergenti dal trattamento (TEAE), eventi avversi di interesse speciale (AESI),
    eventi avversi seri (SAE), riduzione della dose o interruzione del farmaco dello studio a causa di
    tossicità e variazioni nella PS rispetto al basale secondo i criteri ECOG, segni vitali, ECG, FEVS, esami dermatologici e parametri clinici di laboratorio.

    Farmacocinetica (PK):
    • Correlazione tra esposizione PK ed efficacia/sicurezza
    • Parametri PK basati sulla popolazione
    E.5.2.1Timepoint(s) of evaluation of this end point
    Objective response rate: to be assigned a status of a CR or PR, changes in tumor measurements must be confirmed by repeat assessments that must be performed at least 4 weeks after the criteria for response are first met. Patients with unknown or missing response will be treated as
    non responders, that is, they will be included in the denominator when calculating the proportion. Time to confirmed response (CR or PR) (reported in weeks) is defined as the interval between the date of first dose of study medication and the earliest date of first documented confirmed CR or confirmed PR. Patients who do not have a confirmed PR or CR will be censored at the date of the last adequate assessment.
    Tasso di risposta obiettiva: per l’assegnazione dello stato di RC o RP, le variazioni nelle misurazioni del tumore devono essere confermate mediante valutazioni ripetute che devono essere eseguite almeno 4 settimane dopo che i criteri per la risposta siano stati soddisfatti per la prima volta. I pazienti la cui risposta non è nota o è mancante saranno trattati come non rispondenti, ovvero, saranno inclusi nel denominatore per il calcolo della percentuale. Il tempo alla risposta confermata (RC o RP) (riportato in settimane) è definito dall’intervallo tra la data della prima dose del farmaco dello studio e la data iniziale della prima RC o RP confermata documentata. I pazienti che non presentano una RP o RC confermata saranno censurati alla data dell’ultima valutazione adeguata.

    Patients will be eligible to receive study drug for up to 2 years. This will be extended by agreement between the Sponsor and Investigator for patients who exhibit evidence of clinical benefit and tolerability to the drug, and who adhere to the study procedures. The study will end following the last patient last visit.
    I pazienti saranno idonei a ricevere il farmaco dello studio per un massimo di 2 anni. Questo periodo sarà esteso mediante un accordo tra lo sponsor e lo sperimentatore per i pazienti che mostrano evidenza di beneficio clinico e tollerabilità al farmaco, e che ottemperano alle procedure dello studio. Lo studio terminerà dopo l’ultima visita dell’ultimo paziente.
