Brief summary
The purpose of this study is to evaluate the efficacy and safety of guselkumab (CNTO 1959) in the treatment of participants with moderate to severe plaque-type psoriasis (scaly skin rash) who had inadequate response to ustekinumab.
Detailed description
This is a randomized (assignment of study drug by chance), double-blind (participants nor study staff will know the identity of study drugs), multicenter study to evaluate efficacy and safety of guselkumab for the treatment of participants with moderate to severe plaque-type psoriasis who had an inadequate response to ustekinumab. The study will consist of a screening period, open-label and double-blind treatment periods, and a follow-up period. The treatment period will have 2 phases: an open-label treatment phase during which all participants will receive ustekinumab at Weeks 0 and 4 and a blinded treatment phase during which participants with an inadequate Investigator's Global Assessment response (IGA≥2) to ustekinumab at Week 16 will be randomized to receive either guselkumab or ustekinumab through Week 44. Participants with an IGA response of 0 or 1 (cleared or minimal disease) at Week 16 will continue to receive open-label treatment with ustekinumab every 12 weeks through Week 40. All participants will complete a follow-up phase through Week 52 for efficacy and through Week 60 for safety evaluations. The total duration of the study will be approximately 64 weeks (includes a 4-week screening period). Participants' safety will be monitored throughout the study.
Interventions
45 mg or 90 mg given by subcutaneous injection at Weeks 0 and 4 for all participants. Participants with an IGA score of 0 or 1 at Week 16 will also receive ustekinumab every 12 weeks (q12w) from Week 16 to Week 40.
100 mg given by subcutaneous injection at Weeks 16 and 20 and every 8 weeks (q8w) thereafter through Week 44.
Subcutaneous injection at Weeks 16, 28, and 40 to maintain the blind for participants randomized to treatment with guselkumab.
Subcutaneous injection at Weeks 16 and 20 and q8w thereafter through Week 44 to maintain the blind for participants randomized to treatment with ustekinumab.

| Number of Visits at Which Participants Achieved a Psoriasis Area and Severity Index (PASI) 90 Response From Week 28 Through Week 40 | Week 28 through Week 40 | 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 areas were 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. |

| Ustekinumab (Open Label Run-in) All participants received ustekinumab 45 milligram (mg) (participants weighing less than or equal to \[\<=\]100 kilogram \[kg\]) or 90 mg (participants weighing \>100 kg) at Weeks 0 and 4.
