PPPASI assesses severity of palmoplantar pustulosis (PPP) lesions and response to therapy. In PPPASI, palms, soles are divided into 4 regions: right palm(RP), left palm(LP), right sole(RS), left sole(LS), that account for 20 percent (%), 20%,30%,30%, respectively, of total surface area(TSA) of palms, soles. Each area is assessed separately for erythema(E), pustules/vesicles (P), desquamation/scales (D), each rated on a scale (0-4). PPPASI produces score range of 0-72 using formula, PPPASI=(E+P+D)Area*0.2(RP)+(E+P+D)Area*0.2 (LP)+(E+P+D)Area*0.3(RS)+(E+P+D)Area*0.3(LS). Higher a score more the severe disease. Participants who discontinue study agent as they met treatment failure(TF) criterion(lack of efficacy/AE of worsening of PPP/who started a protocol-prohibited medication/therapy that could improve PPP), their baseline value carried forward to post baseline attending visits before and at Week 16 and after TF were applied, remaining missing data were handled with LOCF till Week 60.

Randomized analysis set: all randomized participants at Week 0, whether they received study treatment or not and had any post-baseline efficacy assessment. Missing values were imputed based on TF criterion, last observation carried forward (LOCF) method till Week 60;no imputation performed for missing data after Week 60 (in observational period).

PPSI assesses the severity of PPP lesions and their response to therapy with a score ranging from 0 to 12. A higher score indicates more severe disease. In the PPSI system, the more severely affected location (palms or soles) were to be identified as the evaluation sites at screening that to be assessed at all subsequent visits. Evaluation sites were assessed separately for erythema, pustules/vesicles and desquamation/scale, for most severe skin lesion rated on a scale of 0 to 4. Participants who discontinue study agent as they met a TF criterion, their baseline value carried forward to the post-baseline attending visits before and at Week 16 and after TF were applied, remaining missing data were handled with LOCF till Week 60.

The DLQI is a dermatology-specific quality of life (QOL) instrument designed to assess the impact of the disease on a participant's QOL. It is a 10-item participant-reported outcome questionnaire that, in addition to evaluating overall QOL, can be used to assess 6 different aspects that may affect QOL: symptoms and feelings, daily activities, leisure, work or school performance, personal relationships, and treatment. The DLQI produces a numeric score that can range from 0 to 30. Higher score indicates more severe disease. Participants were analyzed according to the treatment at week 0 or 16. Participants who discontinue study agent as they met a TF criterion, their baseline value carried forward to the post-baseline attending visits before and at Week 16 and after TF were applied, remaining missing data were handled with LOCF till Week 60.

SF-36 consists of 8 individual domains, which are weighted sums of questions in their section. 8 domains are: vitality(VT), physical functioning(PF), bodily pain(BP), general health(GH), Role-Physical(RP), Role-Emotional(RE), social functioning(SF) and mental health(MH). Each of these 8 scales (domains) is scored from 0 to 100 with higher scores indicating better health. Based on scale scores, summary PCS is derived. Scales contributing most to the scoring of the SF-36 PCS include PF,RP,BP and GH. Other domains not noted contribute to scoring but to a lesser degree. Scoring is derived based on an algorithm as presented in Japanese edition manual. Summary PCS score is also scaled from 0 to 100 with higher scores indicating better health. Participants who discontinue study agent as they met a TF criterion, their baseline value carried forward to post-baseline attending visits before and at week 16 and after TF were applied, remaining missing data were handled with LOCF till Week 60.

EQ-5D is designed for self-completion by participants and consists of EQ-5D descriptive system and the EQ visual analog scale (EQ VAS). The EQ-5D descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and unable. The EQ VAS records the respondent's self-rated health on a vertical, VAS where the endpoints are labeled 'Best imaginable health state' (score of 100) and 'Worst imaginable health state' (score of 0). Participants were analyzed according to the treatment at week 0 or 16.
