Efficacy of canakinumab in biologic-naïve versus previously biologic-exposed SJIA patients: a 12 week pooled post-hoc analysis

Canakinumab (CAN), a selective, human anti-IL-1β monoclonal antibody is approved for SJIA in over 30 countries. Efficacy and safety of CAN over 12 weeks have been demonstrated in 2 phase III trials [1]. Out of these trials >60% of the pts received a previous biologic and were switched to CAN due to lack of efficacy or for safety reasons, and may be more refractory to another biologic therapy.
