Session Title: 4M092: Pediatric Rheumatology – Clinical II: JIA (1812–1817)
Session Type: ACR Abstract Session
Session Time: 2:30PM-4:00PM
Background/Purpose: Existing legislation in the United States (US) promotes the study of new medications in children. Biologic disease-modifying-drugs (bDMARDs) and small molecules proven effective and safe in adults with rheumatoid arthritis and other forms of inflammatory arthritis require testing in children with juvenile idiopathic arthritis (JIA) to establish proper dosing, effectiveness, and safety. Several bDMARDs have been approved for the treatment of JIA in the US, but not all children with JIA have a complete clinical response to the available medications and are treated with medications off-label (i.e., anakinra, golimumab, infliximab, rituximab, secukinumab, tofacitinib, ustekinumab). The purpose of this research was to document the continuing medical need for new approved medications for the treatment of JIA.
Methods: The electronic medical record of JIA patients (n= 1599) treated at Cincinnati Children’s Hospital Medical Center (CCHMC) since 2008 were reviewed for medication use and disease activity over time. JIA patients enrolled in the Childhood Arthritis & Rheumatology Research Alliance (CARRA) Registry (n=7,379) were assessed for medication use and disease activity at the most recent Registry visit. Medication need was defined as active JIA despite sequential use of ≥2 bDMARDs. Active JIA was defined as either a) physician-global assessment of JIA activity (MD-global; 0-10; 0 = inactive) >3 OR b) number of active joints (AJC) >3 OR c) patient-global assessment of well-being (Pt-global; 0-10; 0=very well) >3. Medication failure was only assessed for patients with complete data (a-c).
Results: At CCHMC, polyarticular-course JIA (40%), systemic JIA (9%) and juvenile psoriatic arthritis/enthesitis-related arthritis (JPSA/ERA; 17%) were common, and only 16% had persistent-oligoarticular JIA. Overall, use of bDMARDs (n=829; 53%) was common. Systemic JIA (85%) and jPSA/ERA patients (79%) were most commonly treated with bDMARDs. At least 5% (25/1599) of patients had failed >5 bDMARDs. Of 829 biologic users in the CCHMC cohort, 304 (37%) children were exposed to non-approved bDMARDs. Among 278 CCHMC patients with jPSA /ERA 27 (9.7%) had failed >2 bDMARDs. In the CARRA Registry, 46% of JIA patients had polyarticular disease course, 8% systemic JIA, and 18% jPSA/ERA; 4766 (65%) children had received a bDMARD with 1122 (24%) of these children receiving bDMARDs off label. Among 1351 jPSA/ERA patients in the CARRA Registry, about 10% failed >2 bDMARDs with active disease at their most recent visit. Table 1 summarizes medication failures in both cohorts.
Conclusion: Data from a population-based cohort and a large national registry demonstrate a profound medical need for additional therapies to control JIA signs and symptoms, despite the availability of several approved biologic DMARDs. Given FDA approval ensures bDMARD access, the testing of new medications in JIA as they become available to treat adults is critical to further improve JIA outcomes.
