About the Study
​
The BACK-OFF JSpA Study is a randomized pragmatic trial taking place at 31 Children's Hospital sites across the United States and Canada. This study investigates different TNFi de-escalation strategies for children who have sustained asymptomatic disease.

The goal of the study is to help answer the questions that many physicians, patients and families have about stopping medication and the risks involved.
