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.2 Objective of the trial
    E.2.1Main objective of the trial
    This study is modular in design allowing assessment of safety, tolerability and anti-tumour activity of T-DXd in combination with other anti-cancer agents. Combination-treatment modules will have 2 parts: a dose-finding phase (Part 1), and a dose expansion phase (Part 2); the recommended Phase 2 dose (RP2D) determined in Part 1 will be used for the dose-expansion in Part 2.

    The target population of interest in this study is patients with HER2-positive (as per ASCO/CAP 2018 guidelines) advanced/MBC. Part 1 of each module will enroll patients with locally assessed HER2-positive advanced/MBC in second-line or later patients. Part 2 of each module will enroll patients with locally assessed HER2-positive breast cancer who have not received prior treatment for advanced/metastatic disease.

    Part 1: To assess the safety and tolerability, and determine RP2D for the T-DXd combinations

    Part 2: To assess the safety and tolerability of T-DXd monotherapy and T-DXd combinations
    Badanie zaplanowane w sposób modularny, co pozwoli na ocenę bezpieczeństwa, tolerancji i aktywności przeciwnowotworowej T-DXd w leczeniu skojarzonymi (ls). Moduły ls będą się składać z 2 części: fazy ustalania dawki (część 1) i fazy rozszerzonej oceny dawkowania (część 2); w fazie rozszerzonej oceny dawkowania stanowiącej cz. 2 będzie stosowana zalecana dawka fazy 2 (RP2D) ustalona w cz. 1.
    Populacją docelową są pacjenci
    z HER2-dodatnim (wg ASCO/CAP 2018) zaawansowanym/przerzutowym (MBC) rakiem piersi. Do cz. 1 każdego modułu będą włączani pacjenci z ocenionym miejscowo HER2-dodatnim zaawansowanym/MBC rakiem piersi poddawanym leczeniu 2.lub kolejnej linii. Do cz.2 każdego modułu będą włączani pacjenci z ocenionym miejscowo HER2-dodatnim rakiem piersi, wcześniej nie leczeni z powodu tej choroby w stadium zaawansowanym/MBC.
    Część 1: Ocena bezpieczeństwa i tolerancji oraz ustalenie RP2D T-DXd stosowanego w ls.
    Część 2: Ocena bezpieczeństwa i tolerancji T-DXd w monoterapii i w lc.
