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   44237   clinical trials with a EudraCT protocol, of which   7338   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 ).

    Best Overall Response (BOR) by Investigator Assessment
    End point description
    BOR was determined by RECIST v1.1 and defined as best-confirmed response of any of following: complete response (CR), partial response (PR), stable disease (SD) and PD recorded from date of randomisation until disease progression/recurrence. CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in SLD of all lesions. SD: Neither sufficient increase to qualify for PD nor sufficient shrinkage to qualify for PR. PD is defined as at least a 20% increase in the SLD, taking as reference the smallest SLD recorded from baseline or appearance of 1 or more new lesions. PR or CR confirmed at a subsequent tumor assessment, not sooner than 5 weeks after initial documentation or at an assessment later than the next assessment after the initial documentation of PR or CR. SD confirmed at least 6 weeks after randomization. Confirmed PD equal to progression less than or equal to [<=]2 weeks after date of randomization. Full analysis set was used.

    End point description
    EQ-5D-5L is comprised of the following 5 subject-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive overall composite health state index score, with scores ranging from -0.594 to 1. A higher score indicates better health state. Health-related quality of life (HRQoL) analysis set included randomised subjects who had 1 Maintenance Phase Baseline HRQoL assessment and had at least 1 post-Maintenance Phase Baseline HRQoL questionnaire completed. Here, " Number of Subjects Analysed" signifies those subjects who were evaluable for this endpoint and "n" signified those subjects who were evaluable for the specified category at given time points.

    Change From Baseline in European Quality of Life 5-dimensions Health Outcome Questionnaire Through Visual Analogue Scale up to Safety Follow-up (Up to 152.3 Weeks)
    End point description
    EQ-5D-5L is comprised of the following 5 subject-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive overall score using a visual analog scale (VAS) that ranged from 0 to 100 millimeter (mm), where 0 is the worst health, you can imagine and 100 is the best health you can imagine. HRQoL analysis set included randomised subjects who had 1 Maintenance Phase Baseline HRQoL assessment and had at least 1 post-Maintenance Phase Baseline HRQoL questionnaire completed. Here, " Number of Subjects Analysed" signifies those subjects who were evaluable for this endpoint and "n" signified those subjects who were evaluable for the specified category at given time points.

    End point description
    EORTC QLQ-C30 is a 30-question tool used to assess the overall quality of life (QoL) in cancer subjects. It consisted of 15 domains: 1 global health status (GHS) scale, 5 functional scales (Physical, role, cognitive, emotional, social), and 9 symptom scales/items (Fatigue, nausea and vomiting, pain, dyspnoea, sleep disturbance, appetite loss, constipation, diarrhea, financial impact. The EORTC QLQ-C30 GHS/QoL score ranges from 0 to 100; High score indicates better GHS/QoL. Score 0 represents: very poor physical condition and QoL. Score 100 represents: excellent overall physical condition and QoL. HRQoL analysis set included randomised subjects who had 1 Maintenance Phase Baseline HRQoL assessment and had at least 1 post-Maintenance Phase Baseline HRQoL questionnaire completed.

    Change From Baseline in European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Stomach Cancer Specific (EORTC QLQ-STO22 ) Questionnaire Scores up to Safety Follow-up (Up to 152.3 Weeks)
    End point description
    EORTC QLQ-STO22 supplements the EORTC QLQ-C30 to assess symptoms and treatment-related side effects commonly reported in subjects. There are 22 questions which comprise 5 scales (dysphagia, pain, reflux symptom, dietary restrictions, and anxiety) and 4 single items (dry mouth, hair loss, taste, body image). Most questions use 4-point scale (1 'Not at all' to 4 'Very much'; 1 question was a yes or no answer). A linear transformation was used to standardize all scores and single-items to a scale of 0 to 100; higher score=better level of functioning or greater degree of symptoms. HRQoL analysis set included randomised subjects who had 1 Maintenance Phase Baseline HRQoL assessment and had at least 1 post-Maintenance Phase Baseline HRQoL questionnaire completed. Here, " Number of Subjects Analysed" signifies those subjects who were evaluable for this endpoint and "n" signified those subjects who were evaluable for the specified category at given time points.

    End point description
    Adverse event (AE) was defined as any untoward medical occurrence in a subject, which does not necessarily have causal relationship with treatment. A serious AE was defined as an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged in subject hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. The term TEAE is defined as AEs starting or worsening after the first intake of the study drug. TEAEs included both serious TEAEs and non-serious TEAEs. Number of subjects with TEAEs and serious TEAEs were reported. Safety-Maintenance Analysis Set included all subjects who were administered any dose of the maintenance phase study medication or subjects randomised to the chemotherapy arm who are designated to receive BSC only. Subjects included in the treatment arm according to study treatment actually received.

    End point description
    ECOG PS score is widely used by doctors and researchers to assess how a subject’s disease is progressing and is used to assess how the disease affects the daily living abilities of the subject and determine appropriate treatment and prognosis. The score ranges from Grade 0 to Grade 5, where Grade 0 = Fully active, able to carry on all pre-disease performance without restriction, Grade 1 = Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature (like light house work, office work), Grade 2 = Ambulatory and capable of all self-care but unable to carry out any work activities, Grade 3 = Capable of only limited self-care, confined to bed or chair more than 50% of waking hours and Grade 4 = Completely disabled. Cannot carry on any self-care. Totally confined to bed or chair, Grade 5 = Death. Number of subjects with shift in ECOG PS Score to 1 or Higher Than 1 were reported. Safety-Maintenance Analysis Set was used.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    17 Jul 2019
    • To change the primary objective to include OS in PD-L1+ subjects. In addition to OS in all randomised subjects, where PD-L1 status was defined based on a 1% cut-off for tumor cells. • As per the results of the PD-L1 scoring with validated assay available in June 2019, the number of previously projected events (Protocol Version 6) in the PD-L1+ subjects was not be reached. Thus, the condition of meeting the pre- specified number of PD-L1+ events for the Final Analysis data cut-off has been removed as a trigger for the Final Analysis. The Final Analysis was triggered by the events in the ITT population as well as a minimum follow-up time of 18 months for primary analysis which was expected to ensure sufficiently mature data for OS in PDL1+ subjects. The primary analysis of OS in PD-L1+ subjects was conducted at the same time as OS in all randomized subjects with substantially reduced power. • The sampling for Pharmacokinetic (PK) and Antidrug Antibody Analysis (ADA) was limited to 2 years from randomization, as further sampling would not add value to pharmacokinetic and immunogenicity evaluation. Therefore, the last sampling point was at Week 109 to avoid unnecessary burden to the subjects.
