- Registration Number
- NCT02203032
- Lead Sponsor
- Janssen Research & Development, LLC
- 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.

- Primary Outcome Measures
Name Time Method Number of Visits at Which Participants Achieved an Investigator's Global Assessment (IGA) Response of Cleared (0) or Minimal (1) and at Least a 2 Grade Improvement (From Week 16) From Week 28 Through Week 40 Week 28 through Week 40 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).
- Secondary Outcome Measures
Name Time Method 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.
Number of Visits at Which Participants Achieved an IGA Score of Cleared (0) From Week 28 Through Week 40 Week 28 through Week 40 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).
