The purpose of this study is to evaluate the efficacy and safety of guselkumab for the treatment of participants with palmoplantar pustulosis.
This is a phase 3, randomized (study drug assigned by chance), double-blind (neither physician nor participant knows the name of the assigned drug), multicenter (when more than one hospital works on a medical research study) placebo-controlled (an inactive substance that is compared with a medication to test whether the medication has a real effect in a clinical study) study in participants with palmoplantar pustulosis. The study will consist of 3 phases: screening phase (up to 6 weeks), treatment period (week 0 - week 60) and observational period (up to week 84). Participants will be assigned to 1 of 3 treatment groups (200 milligram \[mg\] guselkumab, 100 mg guselkumab or placebo group) using a stratified block randomization method in a 1:1:1 ratio at Week 0 and Group III (placebo) participants will be allocated in a 1:1 ratio to 1 of 2 treatment groups at Week 16. Participants will primarily be assessed for change from baseline in Palmo-Plantar Pustular Area and Severity Index (PPPASI) total score at Week 16. Safety will be monitored throughout the study.

Change From Baseline in Palmoplantar Pustulosis Area and Severity Index (PPPASI) Total Score at Week 16
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.
Time frame: Baseline and Week 16
Change From Baseline in Palmoplantar Severity Index (PPSI) Total Score at Week 16
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.
Time frame: Baseline and Week 16
Percentage of Participants Who Achieved a PPPASI-50 Response at Week 16
PPPASI assesses severity of PPP lesions and their response to therapy. In PPPASI system, palms and soles are divided into 4 regions: right palm, left palm, right sole, and left sole, that account for 20%, 20%, 30%, and 30%, respectively, of TSA of palms and soles. Each of these areas is assessed separately for erythema, pustules/vesicles, and desquamation/scales, each rated on a scale of 0 to 4. PPPASI produces a score range from 0 to 72. Higher score indicates more severe disease. PPPASI-50 response represents participants who achieved at least a 50% improvement from baseline in the PPPASI score. Participants who discontinue study agent as they met a TF criterion were considered as non-responders at Week 16 and after TF were applied, remaining missing data were handled with LOCF till Week 60.

Change From Baseline in the Dermatology Life Quality Index (DLQI) Score
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.

Change From Baseline in the 36-Item Short-Form Health Assessment Questionnaire (SF-36) Physical Component Summary (PCS) Score
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.

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.
