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   43845   clinical trials with a EudraCT protocol, of which   7282   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
    This was randomized, multicenter, open-label, Phase II study of RO5083945 in combination with FOLFIRI versus FOLFIRI plus cetuximab or FOLFIRI alone. The primary objectives were as follows: 1. To gather preliminary evidence of superior activity of RO5083945 added to FOLFIRI versus FOLFIRI + cetuximab in terms of progression free survival (PFS) in participants with Kirsten sarcoma rat virus homology (KRAS) wild-type (WT) colorectal cancer (CRC). 2.To gather preliminary evidence of superior activity of RO5083945 added to FOLFIRI versus FOLFIRI alone in terms of PFS in participants with KRAS mutant CRC.
    Protection of trial subjects
    The investigator ensured that the study was performed in full conformance with the principles of "Declaration of Helsinki" and with the local laws and regulations where the trial was conducted. The study adhered to the principles outlined in "Guideline for Good Clinical Practice" International conference on Harmonization (ICH) Tripartite guideline and compliance with European Union (EU) Clinical Trial Directive (for studies conducted in EU) and adherence to the basic principles of “Good Clinical Practice” as outlined in the current version of 21 code of federal regulations (CFR(, subchapter D, part 312, “Responsibilities of Sponsors and Investigators”, part 50, “Protection of Human Patients”, and part 56, “Institutional Review Boards”, when conducted in United States. A written informed consent is obtained from participants. The investigator or designee explained the trial so that the participants were completely free to refuse or withdraw the study at any point of time. Additional procurement of assent from legally incompetent persons and minors took place according to local laws and international best practice, as it applies to the specific case.

    Progression-Free Survival (PFS) in KRAS WT Participants [1]
    End point description
    PFS was defined as the time between randomization and date of first documented disease progression or death, whichever occurs first. Progressive disease (PD) is at least a 20% increase in the sum of diameter of target lesions, taking as reference the smallest on study including baseline. Participants who neither progressed nor died at the time of the clinical cut-off or who were lost to follow-up were censored at the date of the last tumor assessment showing no progression of disease either during the study or during follow-up. Participants with no post-baseline assessments were censored at the date of randomization. PFS was assessed using Response Evaluation Criteria in Solid Tumors (RECIST) version (v).1.1. criteria. Three participants each in the KRAS WT Cetuximab + FOLFIRI and RO5083945 were censored for PFS analysis. Analysis population: Intent-to-Treat (ITT) population; All randomized participants.

    Percentage of Participants with a Best Overall Response of Complete Response (CR) or Partial Response (PR) (Objective Response Rate)
    End point description
    Best overall response was assessed by RECIST v 1.1 criteria. Participants without any assessments were regarded as non-responders. CR is the disappearence of target lesions. PR is defined as at least 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameter. Analysis was not performed due to no further clinical development of RO5083945.

    Notes
    [21] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: Analysis of pharmacokinetic parameters was performed on RO5083945 and FOLFIRI alone, and so cetuximab + FOLFIRI group was excluded from analysis.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    14 Oct 2010
    Incorporated editorial changes, addition or deletion of certain text.
    16 Dec 2011
    A new section and appendix was added for management of hypomagnesemia. Blood volume estimations were clarified and an additional column of safety blood tests, optional immune functional tests and total blood volumes were updated. Replacement policy was revised to ensure that the primary objective (PFS) was assessed using RECIST 1.1 criteria. Total calcium was changed to calcium ions and corresponding values were added in biochemistry testing. Carcinoembryonic antigen sample collection and urinalysis scheduling was updated in respective sections. The definition of KRAS WT and KRAS mutant treatment groups were revised to align with ICF and electronic CRF (eCRF). Clarified exclusion criterion 08, excluded treatments, scheduling of tumor assessment, baseline assessments for FOLFIRI alone participants (pts), study treatment start of FOLFIRI alone pts, and schedule of assessments. Safety follow-up visit was revised to add information about survival follow-up. Clarified that the screening procedures were required to performed before enrollment and baseline sampling was done after enrolment, because these samples were taken from pts included in the study (i.e. excluding screen failures). Changes made in the ICF that multiple cores/passes were taken during the fresh tumor biopsy to increase the chance of successfully targeting the lesion. Changes made in the ICF that the pt was to be contacted for survival follow-up even after withdrawal from the study.Urine analysis was added to ICF for procedures during treatment. Cetuximab was added as investigational medicinal product in addition with RO5083945. Added a +/- 3 day visit window to allow more flexiblity for scheduling visits during treatment. Subgroup analysis was added to the efficacy analysis. Elevation in aspartate aminotransferase and alanine aminotransferase levels were added in laboratory liver parameters.
    30 Nov 2012
    Updated the phase II study BP22349 in non-squamous non-small cell liver carcinoma analysis to present the benefit/risk of RO5083945 in the former indication. Extended collection of overall survival data and modified the definition for end of study. Clarified on the usage of corticosteroids for prophylactic and reactive treatment for rash. Collection of additional subsequent therapies during survival follow-up after the end of study treatment to detect any imbalance across treatment arms.

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Secondary efficacy analyses such as overall response, duration of response, clinical benefit rate, overall survival, PK and PD analysis were not performed due to no further clinical development of RO5083945.
