A Multi-centre, Randomised, Placebo-controlled, Double-blind, Parallel-group Trial to Evaluate Safety and Efficacy of Spesolimab (BI 655130) in Adult Patients With Ulcerative Pyoderma Gangrenosum (PG) Who Require Systemic Therapy
Study Description
This study has 2 parts. In Part 1, participants are put into groups randomly, which means by chance. 1 group gets spesolimab and the other group gets placebo. Placebo injections look like spesolimab injections, but do not contain any medicine. Every participant has a 2 in 3 chance of getting spesolimab. For the first 8 weeks, participants also take corticosteroid medicine by mouth.
In Part 2, participants are put into groups again. Participants without open ulcers have an equal chance of getting spesolimab or placebo. Participants with open skin ulcers will get spesolimab.
In Part 2, participants are put into groups again. Participants without open ulcers have an equal chance of getting spesolimab or placebo. Participants with open skin ulcers will get spesolimab.
Brief Summary
The purpose of this study is to find out whether a medicine called spesolimab helps people with pyoderma gangrenosum (PG). The main aim is to see whether spesolimab leads to closure of PG ulcers. This study is open to adults with ulcerative PG with at least 1 ulcer that measures between 5 cm^2 to 80 cm^2 in size.

Study Population
Pyoderma Gangrenosum
Inclusion Criteria
- A confirmed diagnosis of ulcerative pyoderma gangrenosum (PG) (≥10 points on the PARACELSUS score) that requires systemic therapy in the opinion of the investigator. The diagnosis needs to be confirmed by an Adjudication Committee. Trial participants with mixed PG subtypes are eligible as long as the target lesion is of the ulcerative subtype
- At least one measurable (defined as measuring ≥5 cm^2) PG ulcer. In trial participants with more than one PG ulcer, the target PG ulcer will be selected by the investigator and confirmed by external Adjudication Committee
- At the time of the Screening Visit, a maximum duration of 6 months since the target ulcer in the current PG episode was diagnosed. Target ulcers >6 months since diagnosis are allowed if they are active and progressing, as judged by the investigator and confirmed by an Adjudication Committee
Exclusion Criteria
- Trial participants with non-PG lesion
- Trial participants with a target PG ulcer measuring >80 cm^2
- Trial participants with chronic, non-inflamed PG wounds or ulcers that are not responsive to immunosuppressive therapy, as determined by an Adjudication Committee
- Presence of active ulcer infection at the Screening Visit (unless treated and resolved prior to administration of the first dose of trial medication) based on investigator assessment
- Presence of persistent or recurring bacterial infection requiring systemic antibiotic therapy; or clinically significant viral, fungal, or parasitic infections within 2 weeks prior to the Screening Visit. Any such infection must be resolved, with treatment completed ≥2 weeks prior to the Screening Visit. No new/recurrent infections should have occurred prior to Visit 2
