Withdrawal Versus Continued TNF Inhibitor Monotherapy Treatment in Children With Inactive Juvenile Idiopathic Arthritis (The Treat-JIA)
Treatment Strategies for Juvenile Idiopathic Arthritis Patients With Sustained Inactive Disease: A Phase 4, Multicentre, Randomised Trial Comparing Maintenance Versus Tapered TNF Alpha Inhibitor Monotherapy - the Treat-JIA Trial
The goal of this clinical trial is to learn whether children and adolescents with juvenile idiopathic arthritis (JIA) who have had inactive disease for a long time can safely discontinue treatment with a tumour necrosis factor inhibitor (TNF-inhibitor) monotherapy. The trial compares TNFi withdrawal with continued treatment at a stable dose. The main question it aims to answer is whether TNF-inhibitor withdrawal increases the risk of disease flare during 12 months of follow-up compared with continued treatment. The trial will also assess time to flare, time to regain inactive disease after a flare, changes in disease activity, and the overall safety of both treatment strategies during the same period. Ninety patients aged 2 to 17 years with non-systemic JIA will take part. All study participants will have had inactive disease for at least 12 months while on TNF-inhibitor monotherapy with adalimumab, etanercept or golimumab. Participants will be randomly assigned either to continue their current TNF-inhibitor treatment at a stable dose or to TNF-inhibitor withdrawal. The baseline and follow-up visits up to 12 months will be performed at three hospitals in Norway and include disease activity assessment through joint examination and the Juvenile Arthritis Disease Activity Score (JADAS-27), and where side effects and other health problems are recorded. A flare is defined as a clinically significant increase in disease activity together with at least one active joint, or as agreement between the treating physician and the participant or parents that a flare has occurred.
