Inclusion criteria

• Diagnosis of Generalized Pustular Psoriasis (GPP), consistent with European Rare and Severe Psoriasis Expert Network (ERASPEN) criteria, defined as primary, sterile, macroscopically visible pustules on non-acral skin (excluding cases where pustulation is restricted to psoriatic plaques). GPP can occur with or without systemic inflammation, with or without plaque-type psoriasis, and be either relapsing (>1 episode) or persistent (>3 months).
• Patient is experiencing a flare, defined as new or worsening of widespread eruption of sterile macroscopically visible pustules, with or without systemic inflammation, as assessed by the treating physician.
• Male or female patients, aged 18 to 75 years at time of enrolment. Women of childbearing potential (WOCBP) must be willing and able to use a highly effective method of birth control per International Council for Harmonization (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 is provided in the patient information.
• Signed and dated written informed consent in accordance with International Council for Harmonization-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the program.
• No satisfactory authorized alternative therapy exists, as assessed by the treating physician.

• Active systemic infections (fungal and bacterial disease) during the last 2 weeks prior to drug administration, as assessed by the treating physician.
• Increased risk of infectious complications (e.g. recent pyogenic infection, any congenital or acquired immunodeficiency (e.g. Human Immunodeficiency Virus (HIV)), past organ or stem cell transplantation), as assessed by the treating physician.
