Long-term efficacy and safety of infliximab plus methotrexate for the treatment of polyarticular-course juvenile rheumatoid arthritis: findings from an open-label treatment extension

Abstract

Objective To assess the long-term efficacy and safety of infliximab plus methotrexate in juvenile rheumatoid arthritis (JRA).

Methods Patients eligible for the open-label extension (OLE, weeks 52–204) received infliximab 3–6 mg/kg every 8 weeks plus methotrexate.

Results Of the 78/122 (64%) children entering the OLE, 42 discontinued infliximab, most commonly due to consent withdrawal (11 patients), lack of efficacy (eight patients) or patient/physician/sponsor requirement (eight patients). Infliximab (mean dose 4.4 mg/kg per infusion) was generally well tolerated. Infusion reactions occurred in 32% (25/78) of patients, with a higher incidence in patients positive for antibodies to infliximab (58%, 15/26). At week 204, the proportions of patients achieving ACR-Pedi-30/50/70/90 response criteria and inactive disease status were 44%, 40%, 33%, 24% and 13%, respectively.

Conclusions In the limited population of JRA patients remaining in the study at 4 years, infliximab was safe and effective but associated with a high patient discontinuation rate.

Clinical trials registration number NCT00036374.
