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   44335   clinical trials with a EudraCT protocol, of which   7366   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.

    General information about the trial
    Main objective of the trial
    The main scope of the trial was to evaluate the efficacy and safety of TACE with irinotecan and mitomycin C compared with TACE with doxorubicin in patients with non-curable intermediate-stage hepatocellular carcinoma (HCC). The primary endpoint was the determination of progression free survival (PFS) time.
    Protection of trial subjects
    This clinical study was designed and shall be implemented and reported in accordance with the protocol, the AMG (Arzneimittelgesetz), the ICH Harmonized Tripartite Guidelines for Good Clinical Practice, with applicable local regulations (including European Directive 2001/20/EC), and with the ethical principles laid down in the Declaration of Helsinki. The trial was authorized/approved by the competent authority (Paul-Ehrlich-Institut, PEI) and the competent ethics committee responsible for the trial (“federführende Ethikkommission”). Before recruitment into the clinical trial, each patient was informed that participation in the study is completely voluntary, and that he or she may withdraw his or her participation in the trial at any time without any declaration of reasons, which will not lead to any disadvantage for the respective patient. The eligibility of a new patient was determined by the local investigator during regular clinical visits. The examinations for the study and the inclusion of the patient were done after detailed written and oral education about aims, methods, anticipated benefits and potential hazards of the study by use of the informed consent forms and after given written consent of the patient. Safety of study treatment was monitored continuously by careful monitoring of all adverse events (AEs) and serious adverse events (SAEs) reported.

    Recruitment
    Recruitment details
    104 patients for were planned. Due to slow recruitment and changes in the therapy landscape the trial was prematurely terminated. The recruitment period was 26 months, June 2020 - August 2022 and took place in 8 centers in Germany.

    Pre-assignment
    Screening details
    Patients with histologically confirmed HCC primarily not suitable for resection, ablation alone or liver transplantation, without extra-hepatic spread. A combined therapy with TACE and subsequent ablation was possible. 25 patients were screened, 5 were ineligible (inclusion/exclusion criteria), 3 did not start trial treatment

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 3 of the patients enrolled in the Standard Arm did not start treatment. These patients were, according to the prespecified definition, excluded from all analysis population.
