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.

    - Evaluer la survie sans progression (SSP) d’après le jugement du médecin-investigateur
    - Evaluer la survie sans progression sous la seconde ligne de traitement (SSP2)
    - Evaluer l’évolution des taux nadir de PSA < 0,2 ng/ml à 3, à 6 et à 12 mois
    - Evaluer le taux de réponse globale, le taux de contrôle de la maladie, le temps jusqu’à la réponse, la durée de la réponse et le temps jusqu’à la progression au niveau des tissus mous

    2. Patients must be adults ≥18 years of age
    3. Patients must have an ECOG performance status of 0 to 2
    4. Patients must have a life expectancy >9 months as determined by the study investigator

    PSA90

    - Le temps de développement d'un CPRC métastatique est défini par le délai entre la date de randomisation et la progression de la maladie malgré le traitement par suppression androgénique (ADT) présentant soit une augmentation continue du taux de sérum de l'antigène spécifique de la prostate (PSA), de la progression de la maladie pré-existante, et ou de l'apparition de nouvelles métastases.

    - la SSP définie par le délai entre la randomisation et la première progression d’après le jugement du médecin-investigateur (progression radiologique, progression clinique, progression du PSA) sous la ligne de traitement suivante ou le décès qu'elle qu'en soit la cause, selon la survenue du premier évènement

    -proportion des patients avec PSA < 0.2 ng/mL

    -taux de réponse globale (ORR), le taux de contrôle de la maladie (DCR), le temps jusqu’à la réponse (DOR), le temps jusqu’à la progression au niveau des tissus mous (TTSTP)

    -Innocuitéi: incidence et sévérité des EIs et des évènements indésirables graves EIGs, modifications dans les analyses biologiques, signes vitaux, ECGs. Toute valeur biologique significative, signes vitaux et anomalies dans l'ECG seront enregistrés comme un EI.

    -tolérance: interruptions de doses, réductions et intensité de dose

    -HRQoL évalué selon le FACT-P pour Functional Assessment of Cancer Therapy-Prostate, le BPI-SF pour Brief Pain Inventory - Short Form

    -qualité de vie EQ-5D-5L (pour European Quality of Life 5 Domain 5 Level scale)

    -(TTSSE) délai entre la radomisation et la survenue de la première fracture osseuse pathologique symptomatique, compression de la moelle épinière, intervention de chirurgie orthopédique liée à la tumeur, recours à la radiothérapie pour soulager les douleurs osseuses, ou décès quelle qu’en soit la cause
    E.5.2.1Timepoint(s) of evaluation of this end point
    For OS: continuously during study treatment and post-treatment follow-up

    ORR, DCR, TTR, DOR, TTSTP will be evaluated based on PCWG3 modified RECIST 1.1

    PSA90 and proportion of patients with PSA < 0.2 ng/mL will be evaluated at 3, 6 and 12 months.

    Continuously during study for other secondary endpoints.
    Pour la SG: continuellement pendant le traitement de l'étude et en suivi post-traitement aux de réponse globale, le taux de contrôle de la maladie, le temps jusqu’à la réponse, la durée de la réponse et le temps jusqu’à la progression au niveau des tissus mous seront évalués selon les critères RECIST v1.1 du PCWG3

    -PSA90 et proportion de patients avec taux de PSA < 0,2 ng/ml à 3, à 6 et à 12 mois.
