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   43865   clinical trials with a EudraCT protocol, of which   7286   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 of berzosertib in association with gemcitabine (Arm A) as well of efficacy of gemcitabine alone (Arm B) will be assessed, independently for each arm, in terms of 6-month progression-free rate (PFR). PFR is defined as the rate of complete or partial response (CR, PR) or stable disease (SD), as per RECIST v1.1. This endpoint is a validated endpoint in STS. Radiological centralized review data will be used for the primary endpoint analysis.
    L’activité antitumorale de l’association gemcitabine + berzosertib ainsi que celle de la gemcitabine seule sera évaluée, indépendamment pour chaque bras, en termes de taux de non-progression à 6 mois (6- month progression-free rate, 6-month PFR).
    Le taux de non-progression à 6 mois est défini par la proportion de patients avec une réponse complète ou partielle ou maladie stable (RECIST v1.1, >= 24 semaines).
    Le critère principal sera évalué à partir des résultats de la relecture radiologique centralisée.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Non-progression-free rate will be evaluated at 6 months after treatment onset
    Le taux de non progression sera évalué à 6 mois après le début du traitement
    E.5.2Secondary end point(s)
    • Antitumor activity of the association will be assessed as well in terms of:
    - Objective response defined as complete response (CR) or partial response (PR) as per adapted RECIST v1.1. The objective response rate (ORR) at 6 months will be reported independently for each arm.
    - Best overall response defined as the best response across all time points (RECIST v1.1). Best overall response rate will be reported independently for each arm.
    - Progression-free survival (PFS) defined as the delay between the start date of treatment and the date of progression (as per RECIST v1.1) or death (from any cause), whichever occurs first. Median PFS, 1- and 2-year PFS rates will be reported independently for each arm.
    - Overall survival (OS) defined as the delay between the start date of treatment and the date of death (of any cause). Median OS, 1- and 2-year OS rates will be reported independently for each arm.
    - Objective response at 6 months and best overall response according to the CHOI criteria.
    • Safety profile of berzosertib in association with gemcitabine. Events will be graded using the Common Terminology Criteria for Adverse Events (CTCAE) from the NCI v5.0. Both AE and SAE will be coded according to the standardized medical terminology MedDRA.
    • Biomarker study: To perform pharmacodynamic (PD)/mechanism of action (MOA) biomarkers analysis as well as predictive biomarkers analysis, in blood and tumor tissue sample at different time points. This may include but not limited to the following: analysis of fixed PBMCs using immunofluorescence and confocal microscopy in order of priority: pSer296 Chk1, total Chk1, gammaH2AX, RAD51, pS317 Chk1 and pS345 Chk1, immune profiling, markers of genetic instability including microsatellite instability).
    • Exploratory analyses of ctDNA for mutations relating to resistance to ATR inhibitor therapy in blood samples collected at baseline.
    • L’activité antitumorale sera évaluée, indépendamment pour chaque bras, en termes de :
    - Réponse objective définie par la proportion de patients avec une réponse complète (RC) ou partielle (RP) (RECIST v1.1). Le taux de réponse objective (ORR) à 6 mois sera reporté indépendamment pour chaque bras.
    - Meilleure réponse globale définie par la meilleure réponse (RECIST v1.1) observée entre l’initiation et la fin du traitement. Elle est déterminée une fois que toutes les données pour un même patient sont connues.
    - Survie sans progression (PFS) définie par le délai entre la date de début de traitement et la date du premier des évènements suivants : progression ou décès (quelle que soit la cause). Le taux de PFS à 1 an, à 2 ans et la médiane de PFS seront reportés.
    - La survie globale (OS) est définie par le délai entre la date de début de traitement et la date de décès (quelle que soit la cause). Le taux d’OS à 1 an, à 2 ans et la médiane d’OS seront reportés.
    - Les réponses objectives à 6 mois et la meilleure réponse globale seront également reportés selon les critères CHOI
    - Le profil de tolérance de l’association sera évalué selon l’échelle de sévérité de la NCI-CTCAE v5.0. Les évènements indésirables graves ou non graves seront codés selon le dictionnaire MedDRA
    • Etude pharmacodynamie : analyse de biomarqueurs sur des échantillons de sang et de tissu tumoral collectés à différents temps de la prise en charge. Ces analyses comprendront notamment (sans être limitées à ces deniers) : PBMC par immunofluorescence, pSer296 Chk1, total Chk1, gammaH2AX, RAD51, pS317 Chk1 and pS345 Chk1 par microscopie confocale, marqueurs immunologiques de l’instabilité génétique incluant l’instabilité des microsatellites.
    • Analyse exploratoire de l’ADN tumoral circulant pour identifier des gènes de résistance aux inhibiteurs d’ATR.
    E.5.2.1Timepoint(s) of evaluation of this end point
    ORR will be evaluated at 6 months after treatment onset.
    Best overall response and safety profile will be evaluated throughout the treatment period with an expected average of 6 months.
    PFS and OS will be evaluated at 1-year and 2-years after treatment onset.
    Tumor biomarkers will be evaluated before treatment onset and at cycle 2 day 1 (each cycle is 21 days).
    Blood biomarkers will be evaluated at Baseline, cycle 2 day 1, cycle 6 day 1 and at progression (each cycle is 21 days).
    Le taux de réponse objective sera évalué à 6 mois après l'initiation du traitement.
    La meilleure réponse sera évaluée tout au long de la période de traitement avec une moyenne estimée de 6 mois.
    La survie sans progression et la survie globale seront évaluées à 1 an et à 2 ans après l'initiation du traitement.
    Le profil de tolérance sera évalué tout au long de la période de traitement avec une moyenne estimée de 6 mois.
    Les biomarqueurs tumoraux seront évalués avant l'initiation du traitement et au jour 1 du cycle 2 (chaque cycle ayant une durée de 21 jours).
    Les biomarqueurs sanguins seront évalués avant l'initiation du traitement, au jour 1 du cycle 2, au jour 1 du cycle 6 et à progression (chaque cycle ayant une durée de 21 jours)
