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 ).

    Close Top of page
    End point title
    Confirmed overall response rate (cORR) by local review [1]
    End point description
    The confirmed overall response rate (cORR) is the percentage of confirmed responses, defined as complete response (CR) or partial response (PR), as assessed by local radiologist/investigator review based on the Response Evaluation Criteria in Solid Tumors (RECIST 1.1). cORR was assessed when all subjects had the opportunity to complete at least 4 post-baseline tumor assessments and after subjects with an initial objective response had the opportunity to have a confirmation scan.
    End point type
    Primary
    End point timeframe
    Tumor evaluations were performed every 6 weeks for the first 12 weeks and then every 8 weeks.
    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: The cORR was provided with a corresponding Clopper-Pearson (exact) binomial 95% CI for the Efficacy Set. If 37 or more confirmed responses were observed in the 90 treated subjects with a centrally confirmed BRAFV600E mutation, corresponding to a lower limit of Clopper-Pearson (exact) binomial 95% CI exceeding 30%, the study was considered to have met its primary endpoint. If more than 90 subjects were enrolled, the lower limit of Clopper-Pearson was to be used for decision.

    Change from baseline in EORTC QLQ-C30 over time
    End point description
    The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire for cancer subjects (EORTC QLQ-C30) includes a global health status/QoL scale, 5 functional scales (physical, role, cognitive, emotional, social) and 9 symptom scales (nausea and vomiting, pain, fatigue, dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties). Each scale of the EORTC QLQ-C30 questionnaire was scored 0 to 100 according to the EORTC recommendations. Changes from baseline in EORTC QLQ-C30 global health status/quality of life (QoL ) over time are presented in this record. Higher scores on the global health status/QoL scale indicate higher QoL. Note: changes from baseline are shown up to Cycle 10 Day 1 (C10D1) and for the 30-day safety follow-up period. Beyond C10D1, less than 10 subjects filled the questionnaire.

    Change from baseline in EQ-5D-5L over time
    End point description
    The EQ-5D-5L consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-5L VAS records the patient’s self-rated health on a vertical visual analogue scale numbered from 0 (“The worst health you can imagine”) to 100 (“The best health you can imagine”). Changes from baseline in EQ-5D-5L VAS over time are presented in this record. Note: changes from baseline are shown up to Cycle 10 Day 1 (C10D1) and for the 30-day safety follow-up period. Beyond C10D1, less than 10 subjects filled the questionnaire.

    The EQ-5D-5L was administered at the Cycle 1 Day 1 (C1D1) Visit (baseline), at the the Day 1 Visit of subsequent cycles (CnD1), at the End of Treatment (EOT) Visit and at the 30-day Safety Follow-up Visit.

    PGIC scores over time
    End point description
    The Patient Global Impression of Change (PGIC) is a measure of patients’ perceptions of change in their symptoms over time. For this assessment, subjects answered the following question: “Since starting treatment, my colorectal cancer symptoms are: (1) very much improved, (2) much improved, (3) minimally improved, (4) no change, (5) minimally worse, (6) much worse or (7) very much worse.” Note: PGIC scores are shown up to Cycle 10 Day 1 (C10D1) and for the 30-day safety follow-up period. The number of subjects who filled the questionnaire was 11 at C11D1 and less than 10 beyond C11D1.

    Adverse events information
    Timeframe for reporting adverse events
    AEs were collected from informed consent signing date up to 30 days after last study treatment administration. Note: disease progression documented ony by medical imaging techniques, with no new or worsening symptoms, was not reported as an AE/SAE.
    Adverse event reporting additional description
    Only TEAEs defined as events that started during the treatment period (from first treatment administration up to last administration date +30 days) or that worsened during the study period are reported. All AEs (not only TEAEs) leading to death are reported. Only deaths occurring during the treatment period are reported.

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    The absence of a comparator arm should be noted as a limitation. In addition, the short duration of the follow-up at the data cut-off date does not allow a robust estimate of OS results.
