Experimental Ixekizumab |
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. |

Experimental Guselkumab |
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. |
