E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of Part 1 (Weeks 0 to 16) is to evaluate the optimal dose regimen of SCH 900222 to induce PASI 75 response at Week 16 in subjects with moderate-to-severe psoriasis.The primary objective of Part 2 (Weeks 16-52) is to evaluate the optimal dose regimen to maintain PASI 75 response at Week 52. The primary objective of Part 3 (Weeks 52-72) is to assess the duration of effect of SCH 900222 as determined by the time at which the Week 52 improvement from baseline is reduced by > 50% (ie, disease relapse). The primary safety objective is to assess the safety/tolerability of multiple-dose administration of SCH 900222. |

E.2.2 | Secondary objectives of the trial |
Assess efficacy as defined by PASI 75 at Week 12. Assess efficacy as defined by PGA at Week 16. |
