研究概览

简要总结

The purpose of this study is to demonstrate that Super-Responders (SRe; defined as psoriasis participants who receive on-label guselkumab treatment until week 20 and respond with a Psoriasis Area and Severity Index score (PASI) = 0 at weeks 20 and 28) maintain control of disease until week 68 with prolonged treatment intervals of 16 weeks (guselkumab 100 mg every 16 weeks).

研究组 & 干预措施

Part 2: Guselkumab q8w

Experimental

Participants (Non SRe) in group 2c with a PASI score greater than (>) 0 at week 20 and/or 28 will continue to receive guselkumab 100 mg q8w until week 60.

干预措施: Guselkumab (Drug)

Part 1: Guselkumab

Experimental

Participants in group 1 (Part 1) will receive 100 milligram (mg) guselkumab subcutaneously (SC) at Weeks 0, 4, 12 and 20.

干预措施: Guselkumab (Drug)

Part 2: Guselkumab q8w and Guselkumab q16w

Experimental

Eligible participants from Part 1 will continue to participate in Part 2. Participants (super responder [SRe]) with a Psoriasis Area and Severity Index (PASI) score = 0 at weeks 20 and 28 will be randomized to guselkumab 100 mg every 8 weeks (q8w) (group 2a) or guselkumab 100 mg q16w (group 2b), at weeks 28 to 60. Group 2b will receive placebo injection at weeks 28, 44 and 60 to keep the comparison double blind. Participants losing control of disease (PASI score >5) during study Part 2 (until week 60), will enter the re-treatment arm (group 2d) and receive guselkumab 100mg q8w (at re-treatment week 0), followed by administration at re-treatment-weeks 8 and 16.

干预措施: Guselkumab (Drug)

Part 2: Guselkumab q8w

Experimental

Participants (Non SRe) in group 2c with a PASI score greater than (>) 0 at week 20 and/or 28 will continue to receive guselkumab 100 mg q8w until week 60.

干预措施: Placebo Injection (Drug)

Part 3: Guselkumab Withdrawal

Experimental

Participants from groups 2a and 2b with a PASI score <3 at week 68 will be included in Part 3 (group 3a and 3b) and be withdrawn from guselkumab. Study visits will be conducted every 12 weeks until week 220 (follow-up). Participants with fluctuating disease (PASI score greater than or equal to [>=] 3) at week 68 or PASI >5 (participants losing control of disease) at any visit during part 3 after week 68 will get an opportunity to enter the re-treatment-arm (group 3c) in which participants will receive three guselkumab injections of 100 mg q8w.

结局指标

主要结局

Group 2a and Group 2b: Percentage of Participants Who Achieved an Absolute Psoriasis Area and Severity Index (PASI) Score Less Than (<) 3 at Week 68

时间窗: Week 68

Percentage of participants who achieved an absolute PASI \<3 at Week 68 were reported. The PASI is a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body is divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas is assessed separately for the percentage of the body surface area involved, which translates to a numeric score that ranged from 0 (indicated no involvement) to 6 (90 percent \[%\]-100% involvement), and for erythema, induration and scaling, which are each rated on a scale of 0 to 4. The PASI produces a numeric score that could range from 0 (no psoriasis) to 72 (maximum psoriasis). Higher score indicated greater severity of psoriasis.
