Abstract

Objectives To review the real-life data, to provide an input to the literature concerning treatment of juvenile idiopathic arthritis (JIA) with adalimumab (ADL) biosimilar. Method This multi-centric retrospective study was conducted among children with JIA, followed up for at least 24-weeks from the initiation of ADL biosimilar (ABP 501) treatment. Adverse events and alterations in disease activity scores were figured out. Results The median age of the group was 15.5 (5-18) years. JIA categories were oligoarticular (n =12), enthesitis-related (ERA) (n=24), psoriatic (PsA) (n=6), and polyarticular (n=4). Uveitis was detected at the initiation of the disease (n=3), during the disease course (n=5), or before the diagnosis (n=1). The first-line treatment preferences were ADL biosimilar (n=37) and etanercept (n=9). On the 6th month of ABP 501, 40 (86.9%) patients had achieved complete remission. Six patients (1 PsA, 1 polyarticular JIA, and 4 ERA) had ongoing active arthritis. Furthermore, all except one of the patients had remission of ophthalmologic findings. No life-threatening adverse events were observed. Conclusions ABP 501 has a gradual increase in prescription in pediatric rheumatology. Real-life data of the cohort announce that ADL biosimilar is a suitable and effective treatment option for patients with JIA in case of indication.
