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   43857   clinical trials with a EudraCT protocol, of which   7284   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    To demonstrate equivalence of change in DAS28-CRP score from Baseline to Week 24 between patients treated with GP2015 and patients treated with Enbrel.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.

    Justification: Numbers are correct : TP2 GP2015 : 181 patients completed TP1 and 175 started TP2 ( 3 did not enter TP2 due to Eligibility, 2 withdrew consent and 1 due to IP delay) TP2 Enbrel GP2015 : 172 patients completed TP1 and 175 started TP2 ( 4 due to Eligibility, 1 withdrew consent and 1 due to adverse event)

    Safety: Change in DAS28-CRP score from baseline to week 24 in patients treated with GP2015 and patients treated with Enbrel
    End point description
    Disease activity score (DAS) 28-CRP is based on 28-joint count (tender and swollen joints), C-reactive protein and patient's assessment of global disease activity, values range from 0.96 to 10.0 while higher values mean a higher disease activity. • A DAS28-CRP value >5.1 corresponds to a high disease activity • A DAS28-CRP value between 3.2 and 5.1 corresponds to a moderate disease activity • A DAS28-CRP value between 2.6 and 3.2 corresponds to a low disease activity • A DAS28-CRP value < 2.6 corresponds to remission DAS28-CRP = 0.56 * sqrt(tender28) + 0.28* sqrt(swollen28) + 0.36 * ln(CRP+1) + 0.014 * GDA + 0.96 where • tender28 and swollen28 are the number of tender and swollen joints as assessed using 28-joint count • CRP is C-reactive protein (mg/l) • GDA is the global disease activity measured on a Visual Analogue Scale (VAS) of 100 mm

    Therapeutic equivalence between GP2015 and Enbrel
    Statistical analysis description
    Therapeutic equivalence in terms of change from baseline in DAS28-CRP at week 24 will be concluded if the 95% confidence interval for the LS mean difference between GP2015 and Enbrel is contained within the interval [-0.6; 0.6]. A mixed-model repeated measures analysis was performed for DAS28-CRP change from baseline including treatment, stratification factors, time, the interaction between time (visits) and treatment all as categorical variables, and baseline DAS28-CRP as a continuous variable.

    ACR20 response was defined if a patient fulfilled all 3 criteria below: -20% improvement in tender 68 joint-count -20% improvement in swollen 68 joint-count; And 20% improvement in at least 3 of the following 5 measures: - Patient’s assessment of RA pain (visual analogue scale (VAS) 100 mm), -Patient’s global assessment of disease activity (VAS 100 mm), -Physician’s global assessment of disease activity (VAS 100 mm), -Patient self-assessed disability (HAQ score), -Acute phase reactant (CRP or ESR). ACR50 and ACR70 responses were defined as ACR20 response replacing “20% improvement” by “50% improvement” and “70% improvement”, respectively.

    Treatment period 1- ACR-N scores at Weeks 4, 12 and 24;
    End point description
    ACR-N (American College of Rheumatology percentage of improvement): negative is worsening, positive (up to 100) is an improvement. ACR-N is a single number that characterizes the percentage of improvement from Baseline that a patient has experienced in analogy to ACR20 described above. ACR-N of X (such as 38) means that the patient had achieved an improvement of at least X% (such as 38%) in tender and swollen joints, and an improvement of at least X% (such as 38%) in 3 of the 5 other parameters mentioned above.
