Initial Dosing of BI 655130 in Palmoplantar Pustulosis Patients

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)].

Number of participants with drug-related AEs are presented.

Percentage of participants who achieved >75% reduction in ppPASI score was assessed by ppPASI75.

The percentage change in the ppPASI score from Baseline to Week 16 was measured.

pppPGA was relied on the participant's overall skin lesions status on the lesions of the most severely affected palmoplantar surface of the palms and sole was assessed by investigator as clear (0), almost clear (1), mild (2), moderate (3) and severe (4) at week 16.

Score Wording were:

0 = Clear = No signs of PPP; no scaling or crusts or pustule remains.

• = Almost clear = Slight scaling and/or erythema and / or slight crusts; very few new (yellow) and / or old (brown) pustules.
• = Mild = Scaling and/or erythema and/or crusts; visible new (yellow) and/or old (brown) pustules of limited number and extent.
• =Moderate = Prominent scaling and/or erythema and / or crusting; prominent new (yellow) and / or old (brown) pustules covering most of the area involved.
• =Severe = Severe scaling and/or erythema and / or crusting; numerous new (yellow) or old (brown) pustules with and/or without major conflence covering the entire area of at least 2 palmoplantar surfaces.
