- Signed and dated written informed consent and assent for the current trial 1368-0025, in accordance with ICH-GCP and local legislation prior to admission to the current trial
Who cannot join
- Evidence of flare symptoms of moderate/severe intensity at screening.
- Treatment with any restricted medication as specified in the protocol, or any drugs considered by the investigator likely to interfere with the safe conduct of the study since the last visit of the previous spesolimab trial and during the screening period for the current trial, with the exception of methotrexate, cyclosporine, or retinoids started following rescue treatment for GPP flare in trial 1368-0027.
- Severe, progressive, or uncontrolled hepatic disease, defined as >3- fold Upper Limit of Normal (ULN) elevation in Aspartate Transaminase (AST) or Alanine Aminotransferase (ALT) or alkaline phosphatase, or >2- fold ULN elevation in total bilirubin.
- Patients with congestive heart disease, as assessed by the investigator.
- Relevant chronic or acute infections including human immunodeficiency virus (HIV) or viral hepatitis. A patient can be re-screened if the patient was treated and is cured from acute infection.
- Active or Latent tuberculosis (TB):
Show all 13Show fewer
- Patients with active tuberculosis should be excluded
- Patients will be screened with Interferon Gamma Release Assay (IGRA) such as QuantiFERON®-TB-Gold Plus or T-spot®. Patients with positive IGRA (indicating active or latent tuberculosis) are excluded unless they have completed treatment for active or latent tuberculosis per investigator discretion, at the time of screening.
- Patients with indeterminate QuantiFERON®-TB-Gold Plus or invalid/borderline T-spot® may be retested with IGRA (once) or Tuberculin Skin test (TST).
- TST or any alternative test/procedure (as per local standards) to rule out TB can be performed if IGRA is not available or indeterminate. A TST reaction ≥10mm (≥5mm if receiving ≥15mg/d prednisone or other immunosuppressant) is considered positive. Patients with a positive TST are excluded unless they have completed treatment as above.
- History of allergy/hypersensitivity to a systemically administered trial medication agent or its excipients.
- Any documented active or suspected malignancy at screening, except appropriately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin or in situ carcinoma of uterine cervix.

About this study
Official title: Effisayil™ ON: An Open-label, Long Term Extension Study to Assess the Safety and Efficacy of Spesolimab Treatment in Patients With Generalized Pustular Psoriasis (GPP)
This study is open to people with generalized pustular psoriasis (GPP). People can only take part if they have completed treatment in a previous study with spesolimab (1368-0013 or 1368-0027).
The goal of this study is to find out how well people with GPP tolerate long-term treatment with spesolimab. The study also tests whether spesolimab helps improve GPP symptoms and how quickly the symptoms improve after a flare-up.
Read more
Every participant gets spesolimab for almost 5 years (252 weeks). Depending on their symptoms and whether they had a GPP flare during the previous trial, they get spesolimab every few weeks. When participants have a GPP flare during this trial, they get spesolimab as an infusion into a vein.
Participants visit their doctors regularly. During these visits, the doctors collect information on any health problems of the participants. To assess the study endpoints, doctors regularly check participants' skin.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Spesolimab in people with Generalized Pustular Psoriasis, run by LEO Pharma at 58 sites in 21 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 1 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 58 sites in Malaysia, Germany, China, Russia, France and 16 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Occurrence of treatment emergent adverse events (TEAEs) up to week 252 of maintenance treatment (time frame: Up to 252 Weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Sep 2026.
