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   44353   clinical trials with a EudraCT protocol, of which   7380   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.

    Recruitment details
    01-Jan-2019 until 06-Dec-2021

    Pre-assignment
    Screening details
    Key eligibility criteria were locally advanced urothelial bladder cancer in patients unfit for or refusing cisplatin-based neoadjuvant therapy. However patients needed to be fit for radical cystectomy. 38 subjects were screened, 33 entered into the trial. Reasons for exclusions were metastatic disease or unresectable disease in baseline imaging

    Feasibility analysis
    Statistical analysis description
    For the primary endpoint, an exact test for single proportions was performed to reject the null hypothesis of ≥22.5% of treatment-related delay in surgery at week 15. If the resulting p-value is less than 5%, the study is considered successful. The analysis of the primary endpoint and efficacy endpoints is based on the Full Analysis Set (FAS).

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    26 Nov 2018
    Clarifications and amendments to protocol and ICF during the approval process per request of EC and PEI. Approval of the Amendment in concurrence with initial protocol approval.
    25 Jan 2019
    Clarifications and amendments to protocol and ICF during the approval process per request of EC and PEI prior to start of recruitment.
    20 Sep 2019
    - Corrections and clarifications regarding deviation time of visits and radiological disease-assessments were implemented. - The timepoint for the planned interim safety analysis was clarified to account for speedy recruitment. - Several typing errors were corrected throughout the protocol. - Changes to the SmPC were implemented in the ICF
    26 Nov 2019
    - A change of radiation dose constraints was implemented after independent safety monitoring identified a possible link between patients suffering from insufficiency of the ileo-ileal anastomosis and a higher radiation dose to the small bowel. The tolerated radiation dose to the small bowel was reduced in response. - An additional planned interim safety analysis to review the impact of the changes made in this amendment was implemented after completion of radio-immunotherapy in patient no. 22. - A version change of the SmPC was implemented in the protocol.
    24 Feb 2021
    - Planned study duration was prolonged to account for slowed recruitment due to the covid pandemic. - Exclusion criterion regarding prior administration of chemotherapy was clarified - Inclusion criterion regarding eligibility for radical cystectomy was clarified to account for curative intention - Changes to the SmPC were implemented in the ICF
    03 Jan 2022
    - Changes to the SmPC were implemented in the ICF
