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   43871   clinical trials with a EudraCT protocol, of which   7290   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 ).

    General information about the trial
    Main objective of the trial
    To assess efficacy (objective response rate, ORR) of adding panitumumab to FOLFOXIRI in patients with newly diagnosed metastatic colorectal cancer expressing wild-type RAS Cohort I) Wtih definitively unresectable metastatic disease, with a focus on symptomatic metastatic disease and/or large tumor load, or Cohort II) With chance of secondary resection with curative intent according to recent S3 guidelines of the German Cancer Society. The ORR was to be compared to expectations derived from historical data, which are verified by a randomised control group without the antibody.
    Protection of trial subjects
    This study was planned, analyzed and conducted according to the study protocol and in accordance with the International Conference on Harmonization (ICH) ‚Guideline for Good Clinical Practice E6(R1)‘, CPMP/ICH/135/95, based on the principles of the Declaration of Helsinki (1964) and its October 1996 amendment (Somerset West, South Africa). The study was duly conducted in compliance with the German Arzneimittelgesetz (AMG; German Drug Law), and the corresponding Directive 2001/20/EC. Subjects were fully informed regarding all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time in language and terms appropriate for the subject.

    Secondary Resection Rate - all patients
    End point description
    A higher percentage of patients achieved resectability in the FOLFOXIRI + panitumumab arm (21 of 63 patients; 33.3%) than in the FOLFOXIRI arm (5 of 33 patients; 15.2%), but this result was not statistically significant (OR 2.800 [0.945–8.297]; p-value 0.0893). In cohort I, at least 6 of 43 patients of arm A (14.0%) and none of the patients of arm B were resectable. As was to be expected, the rates were much higher in cohort II, with 15 of 20 patients of arm A (75.0%) and 5 of 11 patients of arm B (45.5%) achieving resectability. Again, in both cohorts, the results in favour of FOLFOXIRI + panitumumab were not statistically significant (Fisher’s exact test p-values 0.0884 and 0.1318, respectively)

    Progression-free survival

    For patients without either of these events (progression/relapse, or death), the PFS time was censored at the date of the patient’s last recorded date without event. The median duration of observation (time from randomisation to last contact / death) was 32.7 months (mean ± SD: 35.4 ± 26.1 months, minimum 0.8, maximum 124.0 months).

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    07 Feb 2011
    - Implementation of local KRAS mutation testing - Exlusion of patients with baseline ECOG > 1
    20 Nov 2011
    o Introduction of a possible FOLFOXIRI pre-cycle in patients waiting for their RAS mutation test result in need of immediate treatment o In an immediate measure of 28 October 2011, after receipt of safety information from another trial with FOLFOXIRI + panitumumab in mCRC, the doses of irinotecan and 5-FU in the experimental arm had been reduced (irinotecan: 165 mg/m2 to 130 mg/m2; 5-FU 3200 mg/m2 to 2400 mg/m2); in consultation with the IDMC, irinotecan 150 mg/m2 and 5-FU 3000 mg/m2 were determined as the start doses in the FOLFOXIRI + panitumumab arm. o Closer safety monitoring because of the risk of severe toxicities and early life-threatening adverse reactions during the first 4 weeks of treatment for early identification of risk patients in order to trake prophylactic / preventive measures. o Implementation of a formal interim analysis
    20 Nov 2013
    o The Contract Research Organisation supporting the trial was changed in September 2013, when ClinAssess took over the services from the previously contracted CRO. This resulted in numerous organisational and administrative changes, including new randomisation, safety reporting, and data management contact points, procedures, and systems. o After receipt of overall survival (OS) and progression-free survival (PFS) data from a clinical trial with panitumumab + FOLFOX showing NRAS and KRAS Exon 2–4 mutations as a significant negative predictive marker for panitumumab + FOLFOX therapy, mandatory RAS mutation testings prior to patient inclusion and restriction of participation to RAS wildtype patients had already been implemented on 24 April 2013 to prevent any harm to patients; moreover, all patients already included had to be tested. In amendment 3, this measure was laid down in the protocol. o As all patients irrespective of their randomisation to the experimental FOLFOXIRI + Panitumumab arm or the standard FOLFOXIRI (alone) arm received 5-FU / folinic acid, oxaliplatin, and irinotecan, FOLFOXIRI had to be considered background medication and panitumumab was the only investigational medicinal product (IMP) of the study.
    29 Sep 2014
    o Response (CR / PR) did no longer need to be confirmed in a subsequent response assessment (CR / PR) no less than 4 weeks after the initial response assessment, because this condition did not represent the clinical reality in this specific patient population o Examinations / restagings in patients being administered a FOLFOXIRI pre-cycle as implemented in amendment 2 were rescheduled.
