Researchers are evaluating the effectiveness of delgocitinib cream 20 mg/g applied twice daily compared to a cream vehicle in treating adults with mild to severe palmoplantar pustulosis (PPP). This phase 2a, double-blind, two-arm trial focuses on adults diagnosed with PPP, a condition characterized by persistent pustules on the palms and/or soles, lasting more than three months. The study aims to assess skin improvement using the PPP Area and Severity Index (PPPASI) and other clinical evaluations over 16 weeks. Participants will be randomly assigned to apply either delgocitinib cream or the cream vehicle twice daily during a 16-week treatment period. The study involves approximately 9 visits over about 18 weeks in total. The trial is designed to compare the two treatments' effects on PPP severity, with a thorough monitoring process throughout the study period. During the trial, participants will undergo clinical assessments including photographic evaluations to confirm PPP diagnosis, PPPASI scoring to measure skin improvement, and physician global assessments. Safety and treatment adherence will be closely monitored. The main outcome measure is the number of participants achieving at least a 75% improvement in PPPASI score from baseline at week 16. The study also includes safety checks and follow-up to ensure participant well-being throughout the trial.
