Study Overview
Brief Summary
The purpose of this study is to evaluate the efficacy of guselkumab for the treatment of palmoplantar psoriasis.
Detailed Description
Chronic plaque psoriasis is the most common form of psoriatic skin disease; however, there is growing evidence that other variants including scalp, nail, inverse, and palmoplantar psoriasis are prevalent, undertreated, and are correlated with an increased risk of psoriatic arthritis that may result in significant morbidity with functional impairment and greater impairment in quality of life. Therefore, the main aim of the study is to provide robust efficacy and safety data on guselkumab treatment for palmoplantar non-pustular psoriasis. The study comprises of a Screening Phase (4 Weeks [Week -4 to 0]), a Treatment Phase (up to Week 48) and a post-treatment follow-up phase (up to Week 56). Key efficacy assessments include physician assessments and patient-reported outcomes questionnaires. Safety evaluations will include 12-lead electrocardiogram at baseline, pregnancy testing and monitoring of vital signs at all visits and recording of adverse events throughout the study. Also, participants will be evaluated for signs and symptoms of active tuberculosis at all visits including follow-up visit. Biomarker assessments will include the evaluation of relevant markers in serum for all participants. The study will have an overall duration of 56 weeks.

Outcomes
Primary Outcomes
Percentage of Participants who Achieve Palmoplantar Pustulosis Psoriasis Area and Severity Index 75 (ppPASI75) Response at Week 16
Time Frame: Week 16
Percentage of participants who achieve ppPASI75 response, defined as improvement greater than or equal to (\>=) 75 percent (%) in the ppPASI score at Week 16 will be reported. The ppPASI is an assessment tool based on the PASI that assesses erythema, pustules, desquamation and the extent of disease of the palms and/or soles.
