An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Therapy with prednisone or another glucocorticoid is required, unless there is documented intolerance in the medical record or a medical condition that contraindicates further use of prednisone. The prednisone dose must be stable for at least 4 weeks prior to the screening visit. 7. Background therapy with at least 1 non-corticosteroid immunosuppressive agent is required at a stable dose for at least 6 weeks prior to the screening visit unless there is documentation that the patient is intolerant, which is defined as side effects that require discontinuation of the medication(s) or an underlying condition that precludes the further use of the IS medication. 8. If an immunosuppressive agent was discontinued prior to the screening visit then there must be a:
  • - 4 week washout for prednisone or methotrexate - 8 week washout for any other IS agent - For discontinuation of biologic therapies, a washout of 5 terminal half lives 9.

If on statin or fibric acid derivative agents, the dose should be stable for 6 weeks prior to Visit 1. 11. Ability of patient or parent to complete self-report questionnaires. 12. Men and women of reproductive potential must agree to use a reliable method of birth control during the 24 week duration of the trial described in the reproductive risks section of this protocol (section 4.3). They must also agree to use a reliable method of birth control for 100 days after the last dose of study drug is administered. 13. Patients must agree to forgo immunization with a live vaccine during the course of the study or within 3 months after discontinuation. 14. Patients must have a letter from the referring rheumatologist or specialist supervising the care of the JDM, agreeing to the patient's participation in the study and to continuing to provide care for the patient, including emergency care during the trial. Core Set Measures:
  • - An MMT-8 score that is no greater than 125/150 - Patient/Parent Global VAS with a minimum value of 2.0 cm on a 10cm scale - CHAQ/HAQ disability index with a minimum value of 0.25 - Elevation of at least one of the muscle enzymes [which includes creatine kinase (CK), aldolase, lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate aminotransferase (AST)] at a minimum level of 1.3 x the upper limit of normal.
  • - Global extra-muscular disease activity score with a minimum value of 2.0 cm on a 10 cm VAS scale

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

JDM is a chronic systemic autoimmune disease with a predominance of muscle and skin inflammation of unknown etiology and varying prognosis. Children with JDM unresponsive to corticosteroids or other immunosuppressive medications face poor clinical and functional outcome and suffer various sequelae of the disease. Abatacept is a fully human soluble recombinant protein consisting of the cytotoxic T cell Lymphocyte Antigen-4 (CTLA4) fused with Fc region of human IgG1 that has been modified to prevent complement fixation and antibody-dependent cellular cytotoxicity. Abatacept binds specifically to the CD80 (B7-1) and CD86 (B7-2) molecules, those expressed on antigen-presenting cells (APCs). Upon engagement of CTLA4 to CD80 or CD86, the resultant inhibition of signal transduction inhibits T cell activation.. The rationale for use of Abatacept in the therapy of JDM includes the expression of CTLA4, CD28, CD86, and CD40 on inflammatory cells of muscle biopsies of patients with DM, as well as CTLA4 and CD28 on muscle cells. A patient's participation in this study will last approximately 24 weeks with possible extension to 48 weeks. At screening, participants will have a physical exam, muscle strength assessment, blood and urine collection, and chest x-ray; they will also be asked to complete several questionnaires. All participants will receive each week subcutaneous injection of Abatacept. Each injection will be given on an outpatient basis. There will be a total of 6 study visits. All participants will visit the outpatient clinic at selected time points for muscle strength testing, a physical exam, disease activity measurements, blood and urine collection, and muscle MRI; they will also be asked to complete several questionnaires. During the study, participants will be monitored closely for improvement or worsening of their disease and for serious drug related side effects.
