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.

Proportion of disease flare
기간: 4, 8 and 12 months
|
Disease flare is defined as a combination of: A clinical significant increase in Juvenile Arthritis Disease Activity Score 27 (JADAS-27*) ≥1.7 from baseline AND active joints ≥1 (swollen, or tender + limited range of motion) OR consensus between treating physician and participant/parents that a clinically significant flare has occurred with need of intensification of antirheumatic treatment. |

Time to disease flare
기간: From enrolment to 12 months follow-up

Time to disease flare is defined as the time from baseline to the time of disease flare. Disease flare is defined as a combination of: A clinical significant increase in Juvenile Arthritis Disease Activity Score 27 (JADAS-27*) ≥1.7 from baseline AND active joints ≥1 (swollen, or tender + limited range of motion) OR consensus between treating physician and participant/parents that a clinically significant flare has occurred with need of intensification of antirheumatic treatment. |

Time to regain inactive disease after flare is defined as the time from disease flare to the time of inactive disease. Disease flare is defined as a combination of: A clinical significant increase in Juvenile Arthritis Disease Activity Score 27 (JADAS-27*) ≥1.7 from baseline AND active joints ≥1 (swollen, or tender + limited range of motion) OR consensus between treating physician and participant/parents that a clinically significant flare has occurred with need of intensification of antirheumatic treatment. Inactive disease is defined according to the Wallace definition: No active arthritis, no active uveitis, no morning stiffness >15 minutes, no systemic features (fever/rash/serositis/splenomegaly/lymphadenopathy due to JIA), a physician global assessment of disease activity 0 on a 0-100 scale) and normalization of C-reactive protien (CRP) and ESR. |
