Biologic Abatement and Capturing Kids' Outcomes and Flare Frequency in Juvenile Spondyloarthritis (BACK-OFF JSpA)
This randomized pragmatic trial will generate knowledge about strategies used to de-escalate tumor necrosis factor inhibitor (TNFi) therapy in patients with juvenile spondyloarthritis with sustained inactive disease and are treated at one of the 21 participating pediatric healthcare systems. This open label study will be conducted in the setting of routine clinical care and will compare the risk and timing of flare (Aim 1) and patients' lived experiences (Aim 2) across three arms.

• Juvenile SpA diagnosis (symptom onset before their 16th birthday):
