研究概览
简要总结
The purpose of this study is to evaluate the efficacy, safety, and tolerability of guselkumab (CNTO 1959) in the treatment of participants with moderate to severe plaque-type psoriasis (scaly skin rash).
详细描述
This is a randomized (assignment of study drug by chance), double-blind (neither the participant or study staff will know the identity of study drugs), placebo- (inactive substance identical in appearance to study drug) and active-comparator-controlled (use of an approved drug to compare with study drug) study of guselkumab. The active comparator study drug is adalimumab, an approved drug for the treatment of moderate to severe plaque psoriasis. Participants who satisfy all inclusion and exclusion criteria will be randomly assigned in a 2:1:1 ratio to one of three treatment groups (arms): Group I (guselkumab 100 mg dose regimen), Group II (placebo then crossover to guselkumab at Week 16), or Group III (adalimumab at standard psoriasis dosing). From Week 28 up to Week 76, treatment for all participants will be based on their level of response. All participants will receive guselkumab every 8 weeks from Week 76 through Week 252 with a final safety follow-up visit at Week 264 (open label treatment period). The end of the study is defined as the time the last participant completes the Week 264 visit. The total duration of the study will be approximately 268 weeks (includes a 4-week screening period). Participants will be monitored for safety throughout the study.

结局指标
主要结局
Percentage of Participants Who Achieved an Investigator's Global Assessment (IGA) Score of Cleared (0) or Minimal (1) in the Guselkumab Group Compared to the Placebo Group at Week 16
时间窗: Week 16
The IGA documents the investigator's assessment of the participants' psoriasis at a given time point. Overall lesions are graded for induration, erythema, and scaling. The participants' psoriasis was assessed as cleared (0), minimal (1), mild (2), moderate (3), or severe (4).
Percentage of Participants Who Achieved Psoriasis Area and Severity Index (PASI) 90 Response in the Guselkumab Group Compared to the Placebo Group at Week 16
时间窗: Week 16
The PASI is a system used for assessing and grading the severity of psoriatic lesions. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these area was assessed separately for the percentage of the area involved, which translates to a numeric score that ranges from 0 to 6, and for erythema, induration, and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that can range from 0 to 72. A higher score indicates more severe disease. A PASI 90 response represents participants who achieved at least a 90 percent improvement from baseline in the PASI score.
