Randomized Placebo Phase Study of Rilonacept in the Treatment of Systemic Juvenile Idiopathic Arthritis (RAPPORT)
Systemic juvenile idiopathic arthritis (SJIA) is a type of arthritis that typically occurs before 16 years of age. SJIA usually involves heat, pain, swelling, and stiffness in the body's joints. It can also involve fever, rash, anemia, and inflammation in various parts of the body. Rilonacept is a drug that can reduce inflammation. The purpose of this study is to determine whether a rilonacept drug regimen initiated early is more effective than a similar rilonacept drug regimen initiated 4 weeks later when treating children and young adults with SJIA.
• Fulfills International League Against Rheumatism (ILAR) criteria for SJIA
• Duration of SJIA lasting at least 6 weeks since onset
• Active disease as defined by at least two joints with active disease
• Not currently receiving methotrexate OR if taking methotrexate, the dose has remained stable or has been discontinued for 4 weeks prior to screening
• Has never received certain biologics OR if previously received biologics, discontinued etanercept for at least 4 weeks prior to screening and discontinued infliximab or adalimumab for at least 8 weeks prior to screening
• Not currently receiving corticosteroids OR if taking oral corticosteroids, the dose has remained stable between 2 and 60 mg/day for at least 2 weeks prior to screening
