Summary

This study tests whether baricitinib, a daily pill, is safe and works for children aged 1 to under 18 with systemic juvenile idiopathic arthritis (sJIA), a chronic inflammatory disease. About 58 children will receive either baricitinib or a standard injected drug (tocilizumab) to compare results. The goal is to reduce joint inflammation and improve daily life, but ongoing treatment is needed to control the condition.
