Disease modifying anti-rheumatic drugs in juvenile idiopathic arthritis: striving for individualized therapy
Disease-Modifying Anti-Rheumatic Drug (DMARD) use in the treatment of juvenile idiopathic arthritis (JIA) has experienced a dramatic evolution since the early introduction of methotrexate in the 1970’s. This renaissance has been primarily driven by innovation in drug discovery and development that has resulted in the approval of a number of protein-based therapeutics targeting disease-specific pathways. Despite the expansion in the number of drugs available in the treatment of JIA, interindividual variation in therapeutic response and drug-associated toxicities continue to be a major concern and has driven efforts towards individualized therapy. Recent advances in pediatric drug development and innovative approaches to identifying a priori predictors of drug response hold the promise for an individualized approach to therapy that will yield the highest efficacy and safety potential for each JIA patient.
