Multi-center, Double-blind, Randomised, Placebo-controlled, Phase IIa Study to Investigate Efficacy, Safety, Tolerability, Pharmacokinetics and Pharmacogenomics of Multiple Intravenous Doses of BI 655130 in Patients With Palmoplantar Pustulosis (PPP)

Number of Participants With Drug-related Adverse Events (AEs)

时间窗: From first drug administration until 16 weeks after the last drug administration, up to 32 weeks.

Number of participants with drug-related AEs are presented.

Percentage of Participants With Palmoplantar (pp) Pustular Psoriasis Area and Severity Index 50 (PASI) (ppPASI50) at Week 16

时间窗: Week 16

Percentage of participants who achieved 50% reduction in ppPASI score was assessed by ppPASI50. ppPASI is modification of PASI score and an investigator assessment of the extent and severity of pustular and plaque lesions on the palms and soles presenting in PPP participants. This tool provides a numeric scoring for participants overall PPP disease state, ranging from 0 to maximum 72, where 0 corresponds to no signs of psoriasis. It is a linear combination of the percent of surface area of skin that is affected on the palms and soles and the severity of Erythema (E), Pustules (P) (total), and scaling (Desquamation (D)). Missing values for severity or area of involvement were not imputed. ppPASI was calculated as a weighted sum of the scores obtained for E, P, D and Area affected (in%) (where area assessed is glabrous skin on the palms/ soles) (A): \[(E+P+D) x A x 0.2 (right palm)\] + \[(E+P+D) x A x 0.2 (left palm)\] + \[(E+P+D) x A x 0.3 (right sole)\] + \[(E+P+D) x A x 0.3 (left sole)\].
