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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To investigate the clinical efficacy of abatacept on disease activity in polymyositis, and dermatomyositis patients as defined by the International Myositis Outcome Assessment Collaborative Study (IMACS) group.
    E.2.2Secondary objectives of the trial
    The secondary objectives:
    • The number of responders in the delayed onset arm compared with active treatment arm at 3 and 6 months
    • The change in the individual components of the IMACS core set measures for disease activity in the delayed onset arm compared with active treatment arm at 3 and 6 months
    • The change in the muscle endurance as tested by the myositis functional index (FI-2) in the delayed onset arm compared with active treatment arm at 3 and 6 months
    • Time to improvement

    To investigate the efficacy after 6 months with active treatment on the following variables:
    • The individual components of the IMACS core set measures for disease activity
    • Muscle endurance as tested by the myositis functional index (FI-2)
    • Health related quality of life assessed by SF-36
    • On signs of inflammation in muscle tissue (repeated muscle biopsies)

    Explorative objective: To investigate the role of T cells in disease mechanisms of polymyositis and dermatomyositis.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Patients with definite or probable polymyositis or dermatomyositis diagnosed according to the diagnostic criteria by Bohan and Peter (30,31).
    2. For polymyositis a muscle biopsy is required that confirmed this disease (performed at any time before the start of the study) and to exclude other conditions unless a patient is positive for myositis specific or myositis associated autoantibodies.
    3. Polymyositis will be included after a judicial process by the three PIs.
    4. Inflammatory active disease based on persisting or worsening muscle weakness, MMT < 150 or low endurance, FI -2 < 20% of upper value together with at least one other sign of active disease: elevated serum levels of muscle enzymes (CK, LD, ASAT, ALAT, above upper limit and being explained by muscle involvement and not eg liver disease), inflammation in recent muscle biopsy (< 3 months) or on MRI scans or active extramuscular disease: skin rash, arthritis or interstitial lung disease (ILD) (as suggested by chest X-ray, high resolution computerized tomography (HRCT), or pulmonary function test).

    5. Persisting disease activity after a minimum of 3 months treatment with prednisolone or equal drug. The treatment with prednisolone (or equal) should include the dose of at least 0.5 mg/kg/day for at least 1 month in the history and should be stable 1 month prior the baseline visit. Maximum dose of glucocorticoids should not exceed the equivalent of Prednisone 30 mg per day at the time of randomisation.
    6. Combination with at least one other immunosuppressive drug, which includes methotrexate (minimum dose 15 mg/week) or azathioprine (minimum dose 100 mg/day) for at least 3 months. The dose of methotrexate or azathioprine should be stable for at least 1 month before the first administration of abatacept.
    7. If methotrexate or azathioprine has had to be stopped or the dose decreased due to documented intolerance, lower dose or absence of these drugs is accepted provided this situation is stable for 1 month before the baseline.
    8. Age between 18 - 80 years.
    9. Signed informed consent.
    E.4Principal exclusion criteria
    1. Patients with other types of inflammatory myopathies including
    - Drug induced myositis.
    - Inclusion body myositis
    - Malignancy associated myositis.
    2. Women who are pregnant or breastfeeding.
    3. Women with a positive pregnancy test on enrolment or prior to start of study drug administration.
    4. Women of Child Bearing age who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for 10 weeks after the last infusion of study medication.
    5. Current symptoms of severe, progressive, or uncontrolled renal, hepatic,
    hematological, gastrointestinal, pulmonary, cardiac, neurological, ophthalmologic or cerebral disease with the exception of those symptoms that are a manifestation of polymyositis or dermatomyositis. Concomitant medical conditions that in the opinion of the investigator might place the subject at unacceptable risk for participation in this study.
    6. Subjects with a history of cancer within the last five years (other than non-melanoma skin cell cancers cured by local resection). Existing non-melanoma skin cell cancers must be removed prior to dosing. Patients with dermatomyositis need to be screened for malignancies according to routine procedures.
    7. Subjects who have a history of clinically significant drug or alcohol abuse. Subjects currently taking methotrexate who admit to consumption of more than an average of 1 alcoholic drink per day.
    8. Subjects with any serious bacterial infection (such as pneumonia, other renal infection and sinusitis), unless treated and resolved with antibiotics or chronic bacterial infection (such as pyelonephritis and chest infection with bronchiectasis) in the previous 3 months.
    9. Subjects with active tuberculosis requiring treatment within the previous 3 years. Subjects with a positive PPD at screening will not be eligible for the study unless they completed treatment for latent TB and have a negative chest x-ray at enrolment. A PPD response that is equal to or greater than 10 mm should be considered a positive test, although more conservative criteria may be applied as determined by the clinical circumstance and investigator according to published guidelines and/or local standards endorsed by the medical society. Quantiferon assay may replace PPD testing and patients are excluded from the study if the test is positive. Quantiferon positive patients who completed treatment for latent tuberculosis according to the local guidelines may be considered for enrolment.
    10. Subjects with herpes zoster that resolved less than 2 months prior to enrolment.
    11. Subjects with evidence (as assessed by the Investigator) of active or latent bacterial or viral infections at the time of potential enrolment, including subjects with evidence of Human Immunodeficiency Virus (HIV) infection.
    12. Significant toxicities associated with concomitant or previous immunosuppressive
    Therapy and anti-TNF therapy that would preclude subjects from participating and completing the study
    13. Patients with clinically apparent immunodeficiency syndrome, (IgA deficiency alone is not an exclusion criterion)
    14. Subjects with any of the following laboratory values:
    • Hgb < 8.5 g/dL.
    • WBC < 3,000/mm3 (3 x 109/L).
    • Platelets < 100,000/mm3 (100 x 109/L).
    • Serum creatinine > 2 times upper limit of normal.
    • Any other laboratory test results that, in the opinion of the investigator, might place the subject at unacceptable risk for participation in this study.
    15. Subjects previously treated with rituximab: B cell levels are less than lower limit of normal as measured by Fluorescent Activated Cell Sorting (FACS) analysis.
    16. For all patients who have received prior rituximab, a normal CD19 B cell count must be documented at the time of screening for this study.
    17. Patients with Large granular lymphocyte (LGL) syndrome (to minimize the risk of including patients with high frequency of CD28 null T cells) that may not benefit from treatment.
    E.5 End points
    E.5.1Primary end point(s)
    The number of responders, defined as improved according the IMACS criteria, after treatment with abatacept for six months.

    Preliminary Definition of improvement (DOI)
    The definition of improvement is based on a core set of clinical and laboratory variables to assess disease activity, an outcome measure developed in an international consensus, recommended for use in clinical trials by the IMACS group. Any 3 of 6 core set measures improved ≥ 20% with no more than 2 (not including MMT) worse by ≥ 25%.

    Abatacept is available for prescription off label in Europe (Sweden and Czech republic but currently not in the UK) and the possibilities to prescribe abatacept may vary between the countries. Where there is a possibility to prescribe abatacept off label we will apply for this, preferentially in patients who have responded during the trial and worsened after having stopped the abatacept treatment.
