ClinicalTrials.gov#: NCT04891640
Study Design: Intervention Trial
PCORnet Infrastructure: Common Data Model (CDM), Single IRB, Patient partners or engagement
Principal Investigator: Pamela F. Weiss
Institution: The Children's Hospital of Philadelphia
PCORnet® Network Partner: PEDSnet
Funder: Patient-Centered Outcomes Research Institute (PCORI); (Project webpage)
Funding Date: 2020
Study Duration: 2021 – 2025
Participating PCORnet® Clinical Research Networks: GPC, OneFlorida+, PaTH, PEDSnet, STAR
Therapeutic Area: Autoimmune (Allergy & Immunology)
Condition: Juvenile Spondyloarthritis
Age Range: 8 Years to 21 Years (Child,  Adult)
Status: Active, not recruiting

Research Question(s):

This trial will compare how patients with inactive spondyloarthritis on tumor necrosis factor inhibitor (TNFi) treatment respond to three treatment options that doctors currently use:

  • Continue standard TNFi medication,
  • Space out the time between usual TNFi medication doses, or
  • Stop the TNFi medication. If we can safely prolong the time between doses or completely take away TNFi therapy in this population, we may remove unnecessary medication exposure, improve patient quality of life, and lower medication costs.
