Clinical Trial Summary

This study is open to people with palmoplantar pustulosis who took part in previous clinical studies of a medicine called spesolimab. Participants who benefited from spesolimab treatment in the previous studies can join this study.

The purpose of this study is to find out how safe spesolimab is and whether it helps people with palmoplantar pustulosis in the long-term. Participants are in this study for up to 5 years. During this time they visit the study site every month to get spesolimab injections under the skin.

At study visits, doctors check the severity of participants' palmoplantar pustulosis and collect information on any health problems of the participants.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects With Treatment Emergent Adverse Events (TEAEs)	TEAEs were defined as all adverse events (AEs) occurring between start of treatment in this extension trial and the end of its residual effect period. Adverse events that started before first intake of trial medication in the extension trial and deteriorated under treatment during the extension trial were also considered as 'treatment-emergent'.	From first administration of study drug until last administration of study drug + 112 days, up to 869 days.
Secondary	Percent Change in Palmoplantar Pustulosis Area and Severity Index (PPP ASI) From Baseline in Parent Trial (NCT04015518) at Weeks 48 and 96	Percent change in PPP ASI from baseline in parent trial is reported. The adaptation from Psoriasis Area and Severity Index was used in this trial. The index is a linear combination of the percent of surface area of skin affected on the palms and soles of the body and the severity of erythema (E), pustules (P) and scaling / desquamation (D), providing a numeric score for the overall PPP disease state, ranging from 0 (best outcome) to 72 (worst outcome), calculated as: PPP ASI = [(E+P+D) Area x 0.2 (right palm)] + [(E+P+D) Area x 0.2 (left palm)] + [(E+P+D) Area x 0.3 (right sole)] + [(E+P+D) Area x 0.3 (left sole)]. The weighted sum of the scores obtained for Erythema (E), Pustules (P), desquamation (D) (scaling) were based on a score range from 0: None to 4: Very severe, and the area affected on a score range from 0 (0%) to 6 (90-100%). Percent change was calculated as: (PPP ASI at Week X - PPP ASI at baseline in parent trial)/PPP ASI at baseline in parent trial * 100%.	Week 0 (baseline) and Week 48, Week 96
Secondary	Proportion of Patients With PPP ASI50 Compared to Baseline in Parent Trial (NCT04015518) at Weeks 48, 96	Proportion of patients achieving a 50% decrease in PPP ASI compared to baseline in the parent trial at Weeks 48 and 96 is reported. The calculated index is a linear combination of the percent of surface area of skin affected on the palms and soles of the body and the severity of erythema, pustules and scaling / desquamation, providing a numeric score for the overall PPP disease state, ranging from 0 (best outcome) to 72 (worst outcome), calculated as: PPP ASI = [(E+P+D) Area x 0.2 (right palm)] + [(E+P+D) Area x 0.2 (left palm)] + [(E+P+D) Area x 0.3 (right sole)] + [(E+P+D) Area x 0.3 (left sole)]. The weighted sum of the scores obtained for Erythema (E), Pustules (P), desquamation (D) (scaling) were based on a score range from 0: None to 4: Very severe, and the area affected from 0 (0%) to 6 (90-100%). Proportion was calculated as: Patients with PPP ASI50 at Week X/number of evaluable patients at Week X. Non-response imputation (NRI) was used for missing data imputation.	Week 0 (baseline) and Week 48, Week 96
Secondary	Proportion of Patients With PPP PGA of 0 (Clear) or 1 (Almost Clear) at Week 48, 96	Proportion of patients with PPP PGA of 0 (clear) or 1 (almost clear) is reported. The Palmoplantar Pustulosis Physician Global Assessment (PPP PGA) was used to assess the patient's skin presentation on the palms and soles. The investigator scored the individual components (erythema, pustules and scaling/crusting) from 0 to 4 as clear, almost clear, mild, moderate or severe. The PPP PGA was analyzed as PPP PGA total score including erythema, pustules and scaling, and as PPP PGA pustules score for pustules only. Number of patients with PPP PGA of 0/1 at Week X/number of evaluable patients at Week X was calculated. NRI approach was used for missing data imputation.; The PPP PGA total score was derived as the mean of all individual components: 0 = If mean=0, for all three components: = If 0 < mean <1.5; = If 1.5 <= mean <2.5; = If 2.5 <= mean <3.5; = If mean >=3.5	Week 48 and Week 96
