THU0549 Absence of Association Between Drug Exposure and Infection in Patients With Polyarticular-Course Juvenile Idiopathic Arthritis and Inadequate Response to Biologic or Non-Biologic DMARDS Treated With SC and IV Abatacep

Publication: Annals of the Rheumatic Diseases


Background Infections are the most common expected AEs linked to biologic (b) DMARDs in paediatric patients (pts) with juvenile idiopathic arthritis (JIA). Blood concentrations achieved with bDMARDs vary greatly between individual pts. It is not known if higher abatacept (ABA) exposure is linked to higher infection risk in paediatric populations.
