Phase 3 Study to Test the Safety and Effectiveness of Bimekizumab in Adults With Palmoplantar Pustulosis

What this Trial Is About

This clinical trial investigates the efficacy and safety of bimekizumab compared with placebo in adults with palmoplantar pustulosis PPP, a skin condition causing pustules on the palms and soles. The study is a Phase 3, randomized, double-blind, placebo-controlled trial with an open-label extension, aiming to evaluate treatment responses and safety outcomes in participants diagnosed with PPP for at least 24 weeks and who are candidates for systemic therapy or phototherapy. Participants are randomly assigned to one of two groups one group receives bimekizumab for the entire study duration, while the other receives placebo initially before switching to bimekizumab in the maintenance phase. Treatments are given at specified time points throughout the study, which includes an initial treatment period followed by a maintenance period under open-label conditions. During the study, participants undergo assessments including the Palmoplantar pustulosis-Investigator Global Assessment PPP-IGA response at Week 16, Palmoplantar Pustulosis Area Severity Index PPPASI responses at Weeks 8 and 16, and quality of life evaluations via the Dermatology Life Quality Index DLQI. Researchers monitor pain scores, adverse events, and serious side effects from baseline through safety follow-up up to Week 117. Participants will be closely observed through regular visits and evaluations during these periods.
