Juvenile idiopathic arthritis (JIA) is an autoimmune, rheumatologic disease characterized by joint inflammation, pain, and stiffness; it encompasses multiple forms of chronic arthritis in children. The burden of the disease can be exacerbated by progressive deterioration from the arthritis, which affects some patients for life. Current treatment of JIA comprises corticosteroids, nonsteroidal anti-inflammatory drugs, and disease-modifying antirheumatic drugs (DMARDs)—including targeted biologics—which are prescribed to control pain, improve function, and reduce inflammation. Driven by the incentives of the Pediatric Research Equity Act and Best Pharmaceuticals for Children Act, the clinical pipeline in JIA is active, comprising oral and biologic DMARDs approved to treat adult rheumatological disorders—primarily rheumatoid arthritis. According to interviewed JIA experts, there is room for drugs with improved efficacy and/or a milder side-effect profile, to facilitate chronic therapy in the management of JIA.
