UK JIA Biologics Register: the BCRD and BSPAR Etanercept Studies

Discovering more about new treatments for children and young people with Juvenile Idiopathic Arthritis.

What are the studies about?

Two studies called Biologics for Children with Rheumatic Diseases (BCRD) and BSPAR Etanercept Study (BSPAR ETN) are underway at hospitals throughout the UK to look at the safety and effectiveness of biologic and biosimilar treatment for Juvenile Idiopathic Arthritis (JIA).

As part of the studies, long term follow-up information regarding changes to the disease and any newer illnesses is collected to determine the safety and effectiveness of these types of treatments.
