Ixekizumab
Guselkumab
A starting dose of 160 milligram (mg) of ixekizumab was given as 2 subcutaneous (SC) injections at Week 0. During the Induction Period, ixekizumab 80 mg was given every 2 weeks (Q2W) at Weeks 2, 4, 6, 8, 10, and 12. During the Extension Period, ixekizumab 80 mg was given as 1 SC injection (Q4W) every 4 weeks at Weeks 16 and 20. The Post Treatment Follow Up Period was for safety monitoring following the last treatment period.
During the Induction Period, guselkumab 100 mg was given as 1 SC injection at Weeks 0, 4 and 12. 1 placebo injection (to maintain the blind) was given at Weeks 0, 2, 6, 8, and 10. During the Extension Period, guselkumab 100 mg was given at Week 20. 1 placebo injection (to maintain the blind) was given at Week 16. The Post Treatment Follow Up Period was for safety monitoring following the last treatment period.
