Long Term Treatment Strategies and Effectiveness of Secukinumab in Patient With JIA Subtypes of JPsA and ERA: Study From German BIKER Registry.

This is a multicenter, non-interventional cohort study with a combined data collection principle based on secondary use of data and primary data collection from the existing BIKER registry among pediatric patients with a recorded diagnosis of ERA or JPsA who have been treated with secukinumab.

The primary objective of this study is to characterize potentially less demanding long-term treatment strategies (e.g., dose tapering, treatment withdrawal followed by treatment re-initiation as needed) and to characterize their effectiveness (evaluated by occurrence of disease flares) in children and adolescents with Enthesitis-Related Arthritis (ERA) or Juvenile Psoriatic Arthritis (JPsA) categories documented in the German Biologics in pediatric rheumatology (BIKER) registry who received secukinumab and achieved inactive disease.

The date of first treatment/prescription of secukinumab will be considered as the index date. The baseline period to evaluate the demographic and clinical characteristics includes the index date and up to 1 year prior to the index date; if no record is available at the index date whichever record is closest to the index date will be used. For JIA-related variables, such as JIA-related manifestations, the evaluation will not have a specific time limit prior to the index date."
