Summary
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.
