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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective is to demonstrate the efficacy of avapritinib based on progression-free survival (PFS) determined by central radiological assessment per mRECIST, version 1.1 in patients with advanced GIST following 2 or 3 regimens of prior treatment, including imatinib, compared to patients treated with regorafenib.
    L’obiettivo primario è dimostrare l’efficacia di avapritinib in base alla sopravvivenza libera da progressione (PFS) determinata mediante valutazione radiologica centrale secondo la versione 1.1 dei criteri modificati di valutazione della risposta nei tumori solidi (mRECIST) nei pazienti con GIST avanzato dopo 2 o 3 precedenti regimi di trattamento, compreso imatinib rispetto ai pazienti trattati con regorafenib.
    E.2.2Secondary objectives of the trial

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is progression-free survival (PFS), based on central radiological assessment per mRECIST, version 1.1, in patients with advanced GIST. PFS is defined as time from randomization to disease progression, or death due to any cause, whichever occurs first.
    L’endpoint primario è la PFS, in base alla valutazione radiologica centrale secondo i criteri mRECIST, versione 1.1, nei pazienti con GIST avanzato. La PFS è definita come l’intervallo di tempo compreso tra la randomizzazione e la progressione della malattia o il decesso per qualsiasi causa, a seconda dell’evento che si verifica per primo.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary analysis for PFS is based on the central radiological assessment of progressive disease (PD) per mRECIST, version 1.1 in the ITT population. Patients without disease progression or death at the time of analysis will be censored at their last date of tumor evaluation. Patients who withdraw from the study and receive subsequent antineoplastic therapy without documented PD will be censored at the time of the last adequate (CT or MRI scan available) disease assessment. For PD documented between scheduled evaluations, the actual date of PD will be used not the date of the next scheduled evaluation. For death or PD after no more than 1 missed evaluation, the date of the event will be the date of PD or death, whichever occurs first.
    L’analisi primaria per la PFS è basata sulla valutazione radiologica centralizzata della PD secondo criteri mRECIST v1.1 nella popolazione che si intende trattare. Pazienti senza PD o deceduti al momento dell’analisi saranno censurati alla loro ultima data di valutazione del tumore. Pazienti che si ritirano dallo studio e ricevono successivamente una terapia antineoplastica senza PD documentata saranno censurati al tempo dell'ultima valutazione adeguata della malattia. Per la PD documentata tra le valutazioni programmate, sarà usata la data effettiva della PD e non la data della successiva valutazione programmata. Per decesso o PD dopo non più di 1 valutazione saltata, la data dell’evento sarà la data di PD o decesso, a seconda dell’evento che si verifica per primo.

    E.5.2.1Timepoint(s) of evaluation of this end point
    The Kaplan-Meier method will be used to estimate the distribution of PFS for each treatment group. The primary treatment comparison is based on a stratified log-rank test in the intent-to-treat population. The hazard ratio, and its 95% confidence interval (CI), are to be estimated based on a stratified Cox's model with treatment as the explanatory variable. Stratification factors include treatment regimen (third vs. fourth), geographic region (Asia vs. rest of the world), and mutation status measured in ctDNA or a tumor sample (PDGFRa D842V mutation present vs absent ). One interim analysis for futility and efficacy will be performed at approximately 50% of the information fraction (ie, 132 PFS events).
    Per stimare la distribuzione della PFS per ciascun gruppo di trattamento sarà usato il metodo di Kaplan-Meier. Il confronto primario tra trattamenti si basa sul test dei ranghi logaritmici stratificato nella popolazione che si intende trattare. Il rapporto di rischio e il rispetto intervallo di confidenza (CI) al 95% devono essere stimati in base a un modello stratificato di Cox con trattamento come variabile esplicativa. I fattori di stratificazione includono regime di trattamento (terzo vs quarto), regione geografica (Asia vs resto del mondo) e stato mutazionale misurato nel ctDNA o campione tumorale (presenza vs assenza di mutazione PDGFRa D842V). Sarà eseguita un’analisi ad interim per futilità ed efficacia all’incirca al 50% della frazione di informazioni (ovvero, 132 eventi PFS).
