At Week 16, subjects who have been randomized to secukinumab groups at BSL (Groups 1-3) will be classified as either responders (≥20% improvement from BSL in both tender joint count (TJC) and swollen joint counts (SJC)) or non-responders (<20% improvement from BSL TJC or SJC), however they will continue on the same treatment irrespective of their response status.
