Conditions

Palmoplantar Pustulosis

Brief 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.

MeasureTime frameDescription
Number of Subjects With Treatment Emergent Adverse Events (TEAEs)From first administration of study drug until last administration of study drug + 112 days, up to 869 days.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'.

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%.

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.
Proportion of Patients With PPP PGA of 0 (Clear) or 1 (Almost Clear) at Week 48, 96Week 48 and Week 96Proportion 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: 1. = If 0 \< mean \<1.5 2. = If 1.5 \<= mean \<2.5 3. = If 2.5 \<= mean \<3.5 4. = If mean \>=3.5

Recruitment details

This study was a phase II, open-label, single arm, to test the safety and efficacy of long-term treatment with Spesolimab in patients with Palmoplantar Pustulosis (PPP) who took part in previous studies with Spesolimab

Pre-assignment details

All subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) strictly met all inclusion and none of the exclusion criteria. Subjects were not to be allocated to a treatment group if any of the entry criteria were violated.

Participants by arm

ArmCount
Spesolimab (BI 655130)
The patients were administered 600 milligram (mg) Spesolimab (BI 655130) prefilled syringes subcutaneously in thighs or abdomen every 4 weeks for up to 5 years (260 weeks). Patients were to continue the treatment until no longer benefited under the patient opinion or investigator assessment, or withdrawal of consent, whichever occurred first.
