Proportion of Participants Achieving Clinical Response at Week 16 Primary · Baseline and Week 16

Clinical Response was defined as reduction of the Generalized Pustular Psoriasis (GPP) total skin score (range 0-9, with 9 representing severe symptoms) relative to baseline (Day 1), according to Japan Dermatology Association (JDA) severity index in GPP medical care guideline 2014. The total skin score is the combined skin scores for area of erythema (redness), area of erythema with pustules (small pockets of pus), and area of edema (swelling). Clinical Response was defined as the improvement (reduction) of total skin score of at least 1 point (if the participant's baseline total skin score wa
