Korea Xeljanz Post-marketing Surveillance for Juvenile Idiopathic Arthritis

Active, not recruiting

• Conditions: Polyarticular Juvenile Idiopathic Arthritis; Psoriatic Arthritis, Juvenile

• Registration Number: NCT05754710
• Lead Sponsor: Pfizer

Brief Summary

This study is to assess the safety and effectiveness of Xeljanz in Juvenile Idiopathic Arthritis (JIA) patients in routine clinical practice in Korea. JIA patients experience persistent joint pain, swelling and stiffness. This is a prospective observational study.

Xeljanz is a JAK inhibitor. It was first approved in 2014 for rheumatoid arthritis patients in Korea. The ministry of Food and Drug Safety in Korea mandates for a drug manufacturer to report the post-marketing surveillance after drug's approval or indication extension. This study is to see the safety and effectiveness of Xeljanz in Juvenile Idiopathic Arthritis patients in routine clinical practice in Korea.

This study is seeking patients who:

* Are 2 to less than 18 years of age;

* Are given Xeljanz for the treatment of JIA.

The study sponsor will monitor patients' treatment experience for up to 44 weeks. This will help assess the safety and effects of this study medicine.
