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   43889   clinical trials with a EudraCT protocol, of which   7298   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.

    E.3Principal inclusion criteria
    Screening:
    101 Subject has provided informed consent prior to initiation of any
    study specific activities/procedures.
    102 Age ≥ 18 years to 75 years at screening.
    103 Fulfills classification criteria for SLE according to the 2019
    EULAR)/ACR classification criteria for SLE (Aringer et al, 2019), with
    antinuclear antibody ≥ 1:80 by immunofluorescence on Hep-2 cells being present at screening. Anti--dsDNA results based on the Phadia method will be used for SLE classification criteria and for the purposes of hSLEDAI scoring during screening and throughout the study.
    110 Hybrid SLEDAI score ≥ 6 points with a "Clinical" hSLEDAI score ≥ 4
    points. The "Clinical" hSLEDAI is the hSLEDAI assessment score without the inclusion of points attributable to laboratory results, including urine and immunologic parameters. Including the following protocol specific rules:
     Arthritis: for hSLEDAI scoring purposes, arthritis must involve small
    joints in the hands or wrists.
     Alopecia: subjects should have hair loss without scarring; should
    neither have alopecia areata nor androgenic alopecia; and should have a CLASI activity score for alopecia 
     Oral ulcers: ulcers location and appearance must be documented by the investigator.
     Scleritis and episcleritis: the presence of stable SLE-related scleritis
    and episcleritis (ie, that will likely not require initiation/increase in
    immunosuppressants/immunomodulators as outlined in the
    inclusion/exclusion criteria) must be documented by an ophthalmologist and other causes excluded.
     Renal: subjects with urine protein/creatinine ratio < 2000 mg/g (or
    equivalent) in a clean catch spot urine sample can enroll and be scored in the hSLEDAI, provided the subject has a clinical hSLEDAI ≥ 4.
     Pleurisy and Pericarditis: symptoms of pleurisy and pericarditis must be accompanied by objective findings to be scored in the hSLEDAI.
    105 BILAG index score (BILAG 2004) of ≥ 1 A item or ≥ 2 B items.
    106 Must be taking ≥ 1 of the following SLE treatments (or regional
    equivalent):
    hydroxychloroquine, chloroquine, quinacrine, mycophenolate mofetil, azathioprine, methotrexate, dapsone, or oral calcineurin inhibitors, or OCS. A subject may enter the study on OCS alone (prednisone ≥ 10 mg/day or equivalent) only if the subject has previously documented trial of anti-malarial or immunosuppressant treatment for SLE. Subjects must be on a stable dose for ≥ 8 weeks prior to screening for all antimalarials and immunosuppressants, with the exception of OCS doseswhich must be stable for ≥ 2 weeks prior to screening.
    107 For subjects taking OCS, the dose must be ≥ 20 mg/day of
    prednisone or OCS equivalent, and the dose must be stable for ≥ 2 weeks prior to screening visit.
    Day 1 (Baseline):
    The baseline/day 1 visit should occur after confirmation of eligibility by the adjudication team within 33 days after the screening visit. At the baseline/day 1 visit, the following 2 criteria should be assessed prior to randomization:
    108 Stability of SLE treatments: OCS and other
    immunosuppressants/immunomodulator agents and doses must be
    stable since screening visit.
    109 Disease activity: active disease as indicated by clinical hSLEDAI
    score ≥ 4 must be observed (clinical hSLEDAI score is the hSLEDAI
    assessment score without the inclusion of points attributable to
    laboratory results including urine and immunologic parameters)
    E.4Principal exclusion criteria
    231 Lupus nephritis if any of the following are present:
    urine protein creatinine ratio ≥ 2000 mg/g at screening, OR having
    required induction therapy within 1 year prior to screening, OR
    histological evidence of diffuse proliferative glomerulonephritis within 12 weeks prior to screening.
    202 Active CNS lupus within 1 year prior to screening including, but not limited to, aseptic meningitis, ataxia, CNS vasculitis, cranial neuropathy, demyelinating syndrome, optic neuritis, psychosis, seizures, or transverse myelitis.
    232 Currently present or within 1 year prior to screening a diagnosis of any chronic inflammatory disease other than SLE which would interfere with SLE disease assessment.
    204 History of any disease other than SLE that has required treatment with oral or parenteral corticosteroids for > 2 weeks within 4 months prior to screening.
    205 Active infection for which anti-infectives were indicated within 4
    weeks prior to screening visit OR presence of serious infection, defined as requiring hospitalization or intravenous anti-infectives within 8 weeks prior to screening visit.
    206 Active tuberculosis or latent tuberculosis with no documented past history of adequate treatment per local standard of care.
    207 Positive test for tuberculosis during screening defined as: either a
    positive or indeterminate QuantiFERON®-TB or T-spot test OR positive purified protein derivative (PPD) (≥ 5 mm of induration at 48 to 72 hours after test is placed).
    233 Positive for hepatitis B surface antigen (HBsAg); or positive for
    hepatitis B core antibody (HBcAb). A history of hepatitis B vaccination
    without history of hepatitis B infection, negative HBsAg and negative
    HBcAb is allowed.
    234 Positive for hepatitis C antibody
    210 Known history of HIV or positive HIV test at screening.
    235 Presence of 1 or more significant concurrent medical conditions,
    including but not limited to the following: poorly controlled diabetes or hypertension symptomatic heart failure myocardial infarction or
    unstable angina pectoris within the past 12 months severe chronic
    pulmonary disease requiring oxygen therapy multiple sclerosis or any
    other demyelinating disease
    212 Any history of malignancy with the following exceptions:
    resolved non-melanoma skin cancers > 5 years prior to screening
    resolved cervical carcinoma > 5 years prior to screening
    resolved breast ductal carcinoma in situ > 5 years of screening

    investigator, poses a safety risk, will prevent the subject from
    completing the study or will interfere with the interpretation of the study results, or might cause the study to be detrimental to the subject
