GroupInterventionDescription
GuselkumabPlaceboDuring the Induction Period, guselkumab 100 mg was given as 1 SC injection at Weeks 0, 4 and 12. 1 placebo injection (to maintain the blind) was given at Weeks 0, 2, 6, 8, and 10. During the Extension Period, guselkumab 100 mg was given at Week 20. 1 placebo injection (to maintain the blind) was given at Week 16. The Post Treatment Follow Up Period was for safety monitoring following the last treatment period.
IxekizumabIxekizumabA starting dose of 160 milligram (mg) of ixekizumab was given as 2 subcutaneous (SC) injections at Week 0. During the Induction Period, ixekizumab 80 mg was given every 2 weeks (Q2W) at Weeks 2, 4, 6, 8, 10, and 12. During the Extension Period, ixekizumab 80 mg was given as 1 SC injection (Q4W) every 4 weeks at Weeks 16 and 20. The Post Treatment Follow Up Period was for safety monitoring following the last treatment period.
GuselkumabGuselkumabDuring the Induction Period, guselkumab 100 mg was given as 1 SC injection at Weeks 0, 4 and 12. 1 placebo injection (to maintain the blind) was given at Weeks 0, 2, 6, 8, and 10. During the Extension Period, guselkumab 100 mg was given at Week 20. 1 placebo injection (to maintain the blind) was given at Week 16. The Post Treatment Follow Up Period was for safety monitoring following the last treatment period.
Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving 100% Improvement From Baseline in Psoriasis Area and Severity Index (PASI 100)Week 12

The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 100 were defined as having an improvement of at least 100% in the PASI scores compared to baseline.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving PASI 100Week 24

The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 100 were defined as having an improvement of at least 100% in the PASI scores compared to baseline.

Percentage of Participants Achieving PASI 75Week 2

The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 75 were defined as having an improvement of at least 75% in the PASI scores compared to baseline.

Percentage of Participants Achieving PASI 90Week 8

The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 90 were defined as having an improvement of at least 90% in the PASI scores compared to baseline.

Percentage of Participants Achieving Static Physician Global Assessment (sPGA) (0)Week 12

The sPGA is a physician's determination of the participant's psoriasis lesions overall at a given time point categorized by descriptions for induration, erythema, and scaling. For the analysis of responses, the participant's psoriasis is assessed as clear (0), minimal (1), mild (2), moderate (3), severe (4), or very severe (5). An sPGA (0) response was defined as a post-baseline sPGA score of 0.

Percentage of Participants Achieving PASI 50Week 1

The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 50 were defined as having an improvement of at least 50% in the PASI scores compared to baseline.
