The purpose of this study is to evaluate the efficacy of guselkumab for the treatment of palmoplantar psoriasis.
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.
