The primary objective of this study was to evaluate the safety and efficacy of risankizumab (150 mg/mL) administered by prefilled syringe (PFS) for the treatment of adult participants with moderate to severe plaque psoriasis.
This was a Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel group study to evaluate the safety and efficacy of risankizumab 150 mg/mL formulation in PFS in adult participants with moderate to severe plaque psoriasis. The study included a 30-day screening period, a 28-week treatment period with study visits at Weeks 0, 4, 16 and 28, and a subsequent follow-up telephone call at approximately 20 weeks after the last dose of study drug. Study drug dosing consisted of 3 self-administered, subcutaneous (SC) doses on Weeks 0, 4, and 16. Dosing on Week 4 was self-administered at home.

Percentage of Participants Achieving Psoriasis Area Severity Index (PASI) 90 at Week 16
The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at Week 16) / PASI score at Baseline \* 100.
Time frame: At Week 16
Percentage of Participants Achieving Static Physician Global Assessment (sPGA) of Clear or Almost Clear at Week 16
The sPGA is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema, induration, and scaling of psoriatic lesions are scored on a 5-point scale ranging from 0 (none) to 4 (severe). The sPGA ranges from 0 to 4, and is calculated as Clear (0) = 0 for all three; Almost clear (1) = mean \>0, \<1.5; Mild (2) = mean ≥1.5, \<2.5; Moderate (3) = mean ≥2.5, \<3.5; and Severe (4) = mean ≥3.5.
