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   43861   clinical trials with a EudraCT protocol, of which   7284   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
    To determine the efficacy of a maintenance treatment combining Talazoparib and Avelumab after platinum-based chemotherapy in patients with locally advanced/metastatic urothelial carcinoma.
    Efficacy will be evaluated through progression-free survival (PFS).
    •Survie sans progression (PFS) définie comme le temps écoulé entre le début du traitement par Talazoparib plus Avelumab et la première progression de la maladie documentée selon les critères RECIST 1.1 sur la base de l'évaluation de l'investigateur, ou le décès pour toute cause, selon la première éventualité.
    E.2.2Secondary objectives of the trial
    To determine the safety profile of Talazoparib plus Avelumab in maintenance treatment of urothelial carcinoma
    To assess the efficacy of the combination, for whole study population, and according to the response to the initial chemotherapy, through:
    •Overall Survival
    •Duration of tumoral response
    •Objective response rate
    •Disease control rate
    •Duration of treatment by Talazoparib plus Avelumab taken together and separately
    •Time to subsequent therapy (TST)
    To assess Quality of life (QoL) of patients under Talazoparib plus Avelumab treatment (time to QoL deterioration TTD)
    To constitute a blood and tumor banking for further ancillary biological explorations.
    These translational researches may include the determination of the patients’ and disease’s characteristics of tumors according to the alteration of genes involved in DNA repair HRD and PD-L1 status.
    Toxicités de l’association Avelumab plus Talazoparib selon les critères NCI CTCAE v 5.0 :

    • Durée de la réponse tumorale définie comme le temps écoulé entre la date de première réponse objective (réponse complète ou partielle) et la date de première progression de la maladie documentée selon les critères RECIST 1.1 ou la date de décès, quelle qu'en soit la cause, selon la première éventualité.
    • Proportion de patients ayant une réponse partielle ou complète, selon les critères RECIST 1.1
    • Proportion de patients présentant une maladie stable, réponse partielle ou complète, selon les critères RECIST 1.1
    • Durée du traitement définie comme le temps écoulé entre la première dose de traitement et la date d'arrêt définitif du Talazoparib et / ou de l'Avelumab, quelle qu'en soit la cause.

    Progression-Free Survival (PFS) defined as the time from initiation of Talazoparib plus Avelumab treatment to the first documented disease progression per RECIST 1.1 criteria based on investigator’s assessment, or death due to any cause, whichever occurs first.
    • Survie sans progression (PFS) définie comme le temps écoulé entre le début du traitement par Talazoparib plus Avelumab et la première progression de la maladie documentée selon les critères RECIST 1.1 sur la base de l'évaluation de l'investigateur, ou le décès pour toute cause, selon la première éventualité.

    Progression of disease
    Progression de la maladie
    E.5.2Secondary end point(s)
    • Toxicities of the combination of Avelumab plus Talazoparib according to NCI CTCAE v 5.0 criteria
    • Overall survival defined as the time from talazoparib + avelumab initiation to death whatever cause.
    • Duration of tumoral response defined as the time elapsed between first date of objective response (complete or partial response) and date of first documented disease progression according to RECIST 1.1 criteria or date of death, due to any cause, whichever occurs first.
    • Proportion of patients with partial or complete response, according to RECIST 1.1 criteria
    • Proportion of patients with stable disease, partial or complete response, according to RECIST 1.1 criteria
    • Duration of treatment defined as the time elapsed between the first dose of treatment and the date of permanent discontinuation of Talazoparib and/or Avelumab regardless of cause. Patients still on treatment with any study drug at the time of database lock will be censored
    • Time elapsed between the date of initiation of Talazoparib plus Avelumab and the date of initiation of subsequent systemic therapy, respectively. Patients who did not receive any subsequent treatment or who have died prior to receiving subsequent treatment will be censored
    • Scores of quality of life assessed through the French version of the self-administered standardized questionnaire EORTC QLQ-C30 and EUROQOL EQ-5D
    • Survival without deterioration in QoL as assessed using the QLQ-C30 questionnaire and defined as the time interval between the date of initiation of Talazoparib plus Avelumab treatment and date of the first deterioration. Deterioration from baseline is defined as a “minimal clinically important difference” (MCID) of > 10-point out of 100. Deterioration will be considered in ≥ 1 of the following dimensions: global health-related QoL, and fatigue, without significant clinical improvement subsequently or death, regardless of cause.
    Toxicités de l’association Avelumab plus Talazoparib selon les critères NCI CTCAE v 5.0 :
    • Survie globale définie comme le temps entre l'initiation du talazoparib + avelumab et la mort quelle qu'en soit la cause.
    • Durée de la réponse tumorale définie comme le temps écoulé entre la date de première réponse objective (réponse complète ou partielle) et la date de première progression de la maladie documentée selon les critères RECIST 1.1 ou la date de décès, quelle qu'en soit la cause, selon la première éventualité.
    • Proportion de patients ayant une réponse partielle ou complète, selon les critères RECIST 1.1
    • Proportion de patients présentant une maladie stable, réponse partielle ou complète, selon les critères RECIST 1.1
    • Durée du traitement définie comme le temps écoulé entre la première dose de traitement et la date d'arrêt définitif du Talazoparib et / ou de l'Avelumab, quelle qu'en soit la cause. Les patients toujours sous traitement avec un médicament à l'étude au moment de la clôture de la base de données seront censurés.
    • Temps écoulé entre la date d'initiation du Talazoparib plus Avelumab et la date d'initiation du traitement systémique ultérieur, respectivement. Les patients qui n'ont reçu aucun traitement ultérieur ou qui sont décédés avant de recevoir un traitement ultérieur seront censurés.
    • Des scores de qualité de vie seront évalués par la version française de l’auto-questionnaire standardisé EORTC QLQ-C30 et EUROQOL EQ-5D
    • Survie sans détérioration de la qualité de vie, évaluée à l'aide du questionnaire QLQ-C30 et définie comme l'intervalle de temps entre la date de début du traitement par Talazoparib plus Avelumab et la date de la première détérioration. La détérioration par rapport à l'inclusion est définie comme une «différence minimale cliniquement importante» (MCID)> 10 points sur 100. La détérioration sera prise en compte dans ≥ 1 des dimensions suivantes: qualité de vie globale liée à la santé et fatigue, sans amélioration clinique significative ou la mort, quelle qu'en soit la cause.
