A Study to Test Whether Spesolimab Helps People With a Skin Condition Called Pyoderma Gangrenosum

Plain-language 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.
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 infusions look like spesolimab infusions, 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 both parts, participants receive spesolimab or placebo as an infusion into a vein every 4 weeks.
Participants are in the study for about 1.5 years. During this time, they visit the study site 20 times. At study visits, doctors check the participant's skin for signs of PG. The doctors also regularly check participants' health and take note of any unwanted effects. The results of the groups are compared to see whether the treatment works.

Inclusion criteria
. Adult trial participants, aged ≥18 years (if local legislation for age of consent differs, then local legislation will be followed) at screening.
. Signed and dated written informed consent in accordance with International Council on Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial.
. 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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Achievement of complete closure (PGAR-100 (100% pyoderma gangrenosum area reduction)) of the target PG ulcer at any time up to Week 26 and confirmed at the next consecutive visit (at least 2 weeks later)
. Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria and instructions on the duration of use is provided in the participant information and in the protocol.
Exclusion criteria
. Trial participants with non-PG lesions.
. 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.
. "Active or latent tuberculosis (TB)
. Chronic or acute infections including Human immunodeficiency virus (HIV) infections and viral hepatitis (including occult hepatitis); the corresponding laboratory tests will be performed during screening. A trial participant can be re-screened if the trial participant was treated and is cured from the acute infection.
. Severe, progressive, or uncontrolled hepatic disease, defined as \>3x Upper Limit of Normal (ULN) elevation in Aspartate aminotransferase (AST) or Alanine aminotransferase (ALT) or alkaline phosphatase, or \>2x ULN elevation in total bilirubin.
