A Study to Assess the Efficacy of Risankizumab Compared to FUMADERM® in Subjects With Moderate to Severe Plaque Psoriasis Who Are Naïve to and Candidates for Systemic Therapy

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare the efficacy and safety of subcutaneous (SC) risankizumab and oral FUMADERM provided as study medication in participants with moderate to severe plaque psoriasis who are naïve to and candidates for systemic therapy.

Detailed Description
-----------------
The efficacy analysis was performed in the Intent to Treat (ITT) set which included all participants who were randomized. The safety analysis was performed in the safety set which included all participants who received at least one dose of study drug. No participants were excluded from the efficacy analysis. Three participants in the FUMADERM® group discontinued after randomization prior to receiving any study drug and were thus not included in the safety set.

| --- | --- | --- |
| Percentage of Participants Achieving 90% Improvement in Psoriasis Area and Severity Index (PASI90) at Week 24 | 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.

LOCF imputation was used for missing data. | Baseline, Week 24 | 
| Participants With Baseline NAPSI ˃0: Change From Baseline to Week 16 | The NAPSI score is calculated by summing the scores of all the nails which for each nail are the sum of the nail matrix score and nail bed score. Each of these is scored as 0=none, 1=present in 1/4 nail, 2=present in 2/4 nail, 3=present in 3/4 nail, 4=present in 4/4 nail. Each nail has a matrix score (0-4) and a nail bed score (0-4). The total nail score is the sum of those 2 (nail matrix and nail bed) individual scores (0-8). The sum of the total score of all involved fingernails is then the total NAPSI score. The NAPSI score is calculated only if all questions in the case report form are completed. A negative change from Baseline indicates improvement.
