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   43873   clinical trials with a EudraCT protocol, of which   7293   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
    The primary objective of this study is to evaluate the effects of filgotinib versus placebo for the treatment of signs and symptoms of rheumatoid arthritis (RA) as measured by the proportion of participants achieving an American College of Rheumatology 20% improvement response (ACR20) at Week 12.
    Protection of trial subjects
    The protocol and consent/assent forms were submitted by each investigator to a duly constituted Independent Ethics Committee (IEC) or Institutional Review Board (IRB) for review and approval before study initiation. All revisions to the consent/assent forms (if applicable) after initial IEC/IRB approval were submitted by the investigator to the IEC/IRB for review and approval before implementation in accordance with regulatory requirements. This study was conducted in accordance with recognized international scientific and ethical standards, including but not limited to the International Conference on Harmonization guideline for Good Clinical Practice (ICH GCP) and the original principles embodied in the Declaration of Helsinki.
    Background therapy
    All participants continued to receive a stable dose of a permitted protocol-specified conventional synthetic disease-modifying antirheumatic drug (csDMARD(s)) (methotrexate, hydroxychloroquine, sulfasalazine, or leflunomide).

    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 1 participant who was randomized but not treated is not included in the subject disposition table.

    End point description
    ACR20 response was defined as having ≥ 20% improvement from baseline in tender joint count based on 68 joints (TJC68), ≥ 20% improvement from baseline in swollen joint count based on 66 joints (SJC66), and ≥ 20% improvement in at least 3 of the following 5 criteria: Physician’s Global Assessment of Disease Activity (PGA), Subject's Global Assessment of Disease Activity (SGA), participant’s pain assessment, Health Assessment Questionnaire - Disability Index (HAQ-DI) score, and high-sensitivity C-reactive protein (hsCRP). Full Analysis Set included all randomized participants who received at least 1 dose of study drug. Participants with missing outcomes were set as non-responders. For statistical analyses, the hierarchical testing procedure was performed to control the overall type I error rate for the primary and key secondary endpoints.

    DAS28(CRP) is a measure of the participant's disease activity calculated using the tender joint counts (28 joints), swollen joint counts (28 joints), SGA, and hsCRP for a total possible score of 1 to 9.4. Higher values indicate more severe disease activity. Participants in the Full Analysis Set were analyzed. Participants with missing outcomes were set as non-responders.

    Change from Baseline in the Health Assessment Questionnaire - Disability Index (HAQ-DI) Score at Week 12
    End point description
    HAQ-DI is a self-reported tool used to assess the ability to perform tasks in 8 functional categories: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and common daily activities. Responses in each functional category were collected as 0 (without any difficulty) to 3 (unable to do a task in that area). The HAQ-DI score was calculated as the average of the scores of the 8 functional areas and ranges from 0 (no disability) to 3 (completely disabled), when 6 or more categories are non-missing. Participants in the Full Analysis Set with available data were analyzed. For statistical analyses, the hierarchical testing procedure was performed to control the overall type I error rate for the primary and key secondary endpoints.
