prospective observational study to evaluate secukinumab treatment effectiveness in pediatric patients with active juvenile enthesitis-related or psoriatic arthritis

Conditions: Juvenile Idiopathic Arthritis

Summary: this is a multicenter, non-interventional, cohort study in pediatric patients with active juvenile enthesitis-related or psoriatic arthritis

rheumatologists and pediatricians actively managing pediatric enthesitis-related arthritis (era) and juvenile psoriatic arthritis (jpsa) in different regions of russia are planned to participate in the study. to be include in this study, physicians must consult more than 10 pediatric patients with era/jpsa in a typical month. any pediatric patients with active era/jpsa who started secukinumab treatment (index date) within 4-8 weeks prior to inclusion can be enrolled. at the inclusion retrospective data collection is planned, then data will be collected 3 months of treatment), 6, 12, 18, and 24 months after index date. therefore, maximum duration of prospective observation is expected to be 23 months. data collection schedule fits routine (juvenile idiopathic arthritis) jia management guidelines for patients receiving biologics stating that treatment effectiveness should be evaluated at 3 and 6 months after biologic initiation and every 6 months thereafter. at each visit effectiveness and tolerability parameters, as well as the patients' quality of life (qol) will be documented. retrospective data will be collected for medical history and jia treatment, including secukinumab before inclusion, as well to describe all necessary parameters since the index date. expected look-back period is 12 months. initiation of secukinumab treatment will be considered the index date.
