Abstract
Objective: To evaluate the safety of adalimumab in pediatric patients who participated in clinical trials of juvenile idiopathic arthritis (polyarticular juvenile idiopathic arthritis and pediatric enthesitis-related arthritis), psoriasis, and Crohn's disease.
Study design: This analysis included data from 7 global, randomized, and open-label AbbVie-sponsored clinical trials of adalimumab and their open-label extensions conducted between September 2002 and December 31, 2015 (cutoff date for ongoing studies). Patients who received ≥1 dose of adalimumab subcutaneously were included. Adverse events that occurred after the first dose of adalimumab and up to 70 days (5 half-lives) after the last dose were reported and events per 100 patient-years were calculated.
Results: The analysis included 577 pediatric patients, representing 1440.7 patient-years of adalimumab exposure. Across indications, the most commonly reported adverse events (events/100 patient-years) were upper respiratory tract infections (24.3), nasopharyngitis (17.3), and headache (19.9). Serious infections (4.0 events/100 patient-years) were the most frequent serious adverse events across indications; the most commonly reported was pneumonia (0.6 events/100 patient-years). Serious infection rates were 2.7, 0.8, and 6.6 events/100 patient-years in patients with juvenile idiopathic arthritis, psoriasis, and Crohn's disease, respectively. No events of malignancies were reported. One death (accidental fall) occurred in a patient with psoriasis.
Conclusions: The safety profile of adalimumab in pediatric patients with polyarticular juvenile idiopathic arthritis, enthesitis-related arthritis, psoriasis, and Crohn's disease was generally similar across indications; no new safety signals were identified in the treatment of pediatric patients with adalimumab.
