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   44339   clinical trials with a EudraCT protocol, of which   7369   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 ).

    Overall Response Rate (ORR) in PD-L1 Positive Participants
    End point description
    ORR is defined as the percentage of participants whose best overall response is complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors v1.1 assessed by the investigator. Investigators conducted assessments of radiological tumor response by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST version 1.1 about every six weeks during the first 48 weeks of the study and every nine weeks thereafter. CR: Disappearance of all target and non-target lesions and no new lesions. Any pathological lymph nodes must have reduction in short axis to < 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters, persistence of one or more nontarget lesion(s) and/or maintenance of tumor marker level above the normal limits.

    Overall Response Rate (ORR) in the ITT Analysis Set
    End point description
    ORR is defined as the percentage of participants whose best overall response is complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors v1.1 assessed by the investigator. Investigators conducted assessments of radiological tumor response by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST version 1.1 about every six weeks during the first 48 weeks of the study and every nine weeks thereafter. CR: Disappearance of all target and non-target lesions and no new lesions. Any pathological lymph nodes must have reduction in short axis to < 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters, persistence of one or more nontarget lesion(s) and/or maintenance of tumor marker level above the normal limits.

    Change From Baseline in European Quality of Life 5-Dimensions, 5-level (EQ-5D-5L) Visual Analogue Scale (VAS)
    End point description
    The EQ-5D-5L measures health outcomes using a VAS to record a participant's self-rated health on a scale from 0 to 100, where 100 is 'the best health you can imagine' and 0 is 'the worst health you can imagine.' A higher score indicates better health outcomes. Participants in the ITT Analysis Set with available data at baseline and each postbaseline visit are included in the analysis.

    Disease Control Rate in PD-L1 Positive Participants
    End point description
    Disease Control Rate is defined as the percentage of participants who had confirmed CR, PR, or stable disease (SD) assessed by the investigator and the investigator per RECIST v1.1. Investigators conducted assessments of radiological tumor response by CT or MRI per RECIST version 1.1 about every six weeks during the first 48 weeks of the study and every nine weeks thereafter. CR: Disappearance of all target and non-target lesions and no new lesions. Any pathological lymph nodes must have reduction in short axis to < 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters, persistence of one or more nontarget lesion(s) and/or maintenance of tumor marker level above the normal limits. SD: Neither sufficient shrinkage in size of lesions to qualify for PR nor sufficient increase to qualify for PD, and no new lesions.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    20 Aug 2018
    • Increased sample size from 640 to 720 patients. • Added PFS after next line of treatment (PFS2) for the exploratory efficacy analysis, defined as the time from randomization to the objective disease progression after next line of treatment or death from any cause, whichever occurred first. • Modified the description of exploratory biomarkers to “including, but not limited to, PD-L1 expression, Epstein-Barr virus (EBV) infection, microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) status, genomically stable (GS) or chromosomal instability (CIN), immune-related gene expression profiling, tumor infiltrated lymphocytes (TILs), and tumor mutation burden in tumor tissues and/or blood samples.” • Clarified that the patients whose tumors were PD-L1 positive with PD-L1 score ≥ 5% using VENTANA PD-L1 (SP263) Assay. PD-L1 score (previously referred to TIC score in protocol) was the total percentage of the tumor area covered by tumor cells with PD-L1 membrane staining and tumor-associated immune cells with PD-L1 staining at any intensity. • Adjusted the 1-sided alpha of 0.00275 to 0.0025 for the primary efficacy analyses of PFS in the PD-L1 Positive and ITT Analysis Sets. • Adjusted the 1-sided alpha of 0.011 to 0.01 for the primary efficacy analyses of OS in the PD-L1 Positive and ITT Analysis Sets.
