About this study
Official title: 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 of them 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. They will be followed for 12 months at three hospitals in Norway, with regular visits where disease activity is assessed 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion 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.
Measured: 4, 8 and 12 months
Secondary outcomes (8)
Time to disease flare
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.
Measured: From enrolment to 12 months follow-up
Time to regain inactive disease after flare
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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 of them 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. They will be followed for 12 months at three hospitals in Norway, with regular visits where disease activity is assessed 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.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Adalimumab, Etanercept and Golimumab in people with Juvenile Idiopathic Arthritis (JIA), run by Oslo University Hospital at 3 sites in Norway.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 29 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Pernille Bøyesen, MD PhD (+4723070000, boyper@ous-hf.no), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of disease flare (time frame: 4, 8 and 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2026.
