The purpose of this third extension study is to provide additional long-term safety and tolerability data of canakinumab over an 18-month time period on patients who have completed the extension studies CACZ885H2356E2 and CACZ885H2357E2. Overall, the treatment and follow-up period from the initial baseline visit in the core studies, and all subsequent extensions will amount to a total of up to 3 years.The study will provide additional safety data of repeated treatment with on-demand use of canakinumab in patients with gouty arthritis. The study may further be used to optimize patients' Urate Lowering Therapy (ULT) as needed, and collect further safety data on the concomitant use of canakinumab with different ULT regimens.
