Outcome Measures
Primary Outcomes (1)
Proportion of Patients With a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) Pustulation Subscore of 0 Indicating no Visible Pustules at Week 1
The Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) relies on clinical assessment of the Generalized Pustular Psoriasis (GPP) patient's skin presentation. The investigator (or qualified site personnel) scored the erythema, pustules, and scaling of all GPP lesions from 0 to 4. The GPPGA pustulation subscore ranges from 0 to 4 where: 0 = clear; 1. = almost clear; 2. = mild: 3. = moderate; 4. = severe. A lower GPPGA pustulation subscore indicates a better outcome. A GPPGA pustulation subscore of 0 means no visible pustules. The proportion of patients who achieved a GPPGA pustulation subscore of 0 at Week 1 is reported.
At Week 1.

Eligibility Criteria
You may qualify if:
- Patients with GPPGA of 0 or 1 and a known and documented history of GPP per European Rare And Severe Psoriasis Expert Network (ERASPEN) criteria regardless of IL36RN mutation status, with previous evidence of fever, and/or asthenia, and/or myalgia, and/or elevated C-reactive protein, and/or leucocytosis with peripheral blood neutrophilia (above ULN) OR
- \-- Patients with an acute flare of moderate to severe intensity meeting the (ERASPEN) criteria of GPP with a known and documented history of GPP (per ERASPEN criteria) regardless of IL36RN mutation status, with previous evidence of fever, and/or asthenia, and/or myalgia, and/or elevated C-reactive protein, and/or leucocytosis with peripheral blood neutrophilia (above ULN)
- Male or female patients, aged 18 to 75 years at screening.
- Signed and dated written informed consent prior to admission to the study in accordance with ICH GCP and local legislation prior to start of any screening procedures.
- Women of childbearing potential 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. Note: A woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. Tubal ligation is not a method of permanent sterilization. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause
You may not qualify if:
- Patients with SAPHO (Synovitis-acne-pustulosis-hyperostosis-osteitis) syndrome.
- Patients with primary erythrodermic psoriasis vulgaris.
- Patients with primary plaque psoriasis vulgaris without presence of pustules or with pustules that are restricted to psoriatic plaques.
- Drug-triggered Acute Generalized Exanthematous Pustulosis (AGEP).
- Immediate life-threatening flare of GPP or requiring intensive care treatment, according to the investigator's judgement. Life-threatening complications mainly include, but are not limited to, cardiovascular/cytokine driven shock, pulmonary distress syndrome, or renal failure.
- Severe, progressive, or uncontrolled hepatic disease, defined as \>3- fold Upper Limit of Normal (ULN) elevation in AST or ALT or alkaline phosphatase, or \>2-fold ULN elevation in total bilirubin.

Limitations and Caveats
Due to the trial design, a large proportion of patients had received escape medication or non-randomized spesolimab by Week 4, based on worsening, insufficient response, or non-response. This should be taken into account for the interpretation of the results at Week 4. A large proportion of patients in both arms had been treated as non-responders at Week 4, and the true efficacy outcomes for the randomized treatment at this time-point were never observed for the analysis.

Data Sharing
- IPD Sharing
- Will not share
Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
