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   44365   clinical trials with a EudraCT protocol, of which   7389   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 primary objective of Phase I is to determine the dose-limiting toxicity (DLT) of 5FU and panitumumab in combination with radiotherapy and mitomycin, and to derive the maximum tolerated dose (MTD) in patients with localized squamous cell carcinoma of the anus. The primary objective of phase II is to determine the complete response rate 8 weeks after the end of standard radio-chemotherapy treatment (theoretically in week 15) in patients with localized squamous cell carcinoma of the anus, as defined by MRI, endorectal echoendoscopy if necessary, and proctological examination.
    Protection of trial subjects
    This research complies with the recommendations of the Declaration of Helsinki (1964) and its amendments (2000), as well as the Public Health Code (Law No. 2004-806 of August 9, 2004 on public health policy). The investigator undertook to obtain the patient's consent for the clinical and biological studies in writing, after providing adequate information (information sheet and consent forms)

    Primary: Percentage of Patients with Complete Responde to Treatment

    Close Top of page
    End point title
    Percentage of Patients with Complete Responde to Treatment [1]
    End point description
    Complete response was defined by the complete disappearance of the tumor on proctological examination and morphological examinations (MRI and/or echo-endoscopy) and the absence of secondary lesion appearance. The responses were validated by an independent committee: • In the event of a discrepancy between the investigator and the independent committee, the independent committee's response was used; • in case of uncertainty of the investigator on the response, the committee decided on the response in view of the clinical and morphological data; This endpoint was assessed 8 weeks after the end of treatment (week 15). A patient who died (regardless of cause) was considered a failure for the primary endpoint if 32 or fewer patients have a complete response at 8 weeks (71%), the complete response rate cannot be considered significantly higher than 60%. if 33 or more patients have a complete response at 8 weeks (73%), the complete response rate is significantly higher than 60%.

    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Given that this is a single-arm study (and therefore not comparative), no inferential statistics were performed.
