E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to demonstrate a non-flat curve and evaluate the dose-response relationship for 3 subcutaneous dosing regimens of BI 655130 (with each regimen consisting of a single loading dose and a separate maintenance subcutaneous dosing regimen) versus placebo, on the primary endpoint, the time to the first GPP flare onset up to week 48. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objective is to demonstrate superiority versus placebo for each of BI 655130 regimen on the primary endpoint, the time to the first GPP flare onset up to week 48, as well as the key secondary endpoint, the occurrence of at least one GPP flare up to 48 weeks. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients with a known and documented history of GPP per ERASPEN criteria (see Section 3.3.1) regardless of IL36RN mutation status.
2. Patients with a GPPGA score of 0 or 1 at screening and randomization.
3. Male or female patients, aged 12 to 75 years at screening. For all patients, a minimum weight of 40 kg is required.
4. Signed and dated written informed consent and assent in accordance with ICH-GCP and local legislation prior to admission in the trial.
5. Women of childbearing potential (WOCBP)1 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 is provided in the CTP as well as in the patient (or patient’s legal guardian) information.
Additional inclusion criteria will apply. |
|
E.4 | Principal exclusion criteria |
1. Patients with SAPHO (Synovitis–acne–pustulosis–hyperostosis–osteitis) syndrome.
2. Patients with primary erythrodermic psoriasis vulgaris.
3. 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.
4. Treatment with:
a. Any restricted medication as specified in the CTP, or any drug considered likely to interfere with the safe conduct of the study, as assessed by the investigator.
b. Any prior exposure to BI 655130 or another IL36R inhibitor biologic.
5. Increased risk of infectious complications (e.g. recent pyogenic infection, any congenital or acquired immunodeficiency (e.g. HIV), past organ or stem cell transplantation), as assessed by the investigator.
6. Relevant chronic or acute infections including active tuberculosis, human immunodeficiency virus (HIV) infection or viral hepatitis at the time of randomization. A patient can be re-screened if the patient was treated and is cured from the acute infection.
7. Active or Latent TB:
• Patients with active tuberculosis should be excluded
• Patients with a positive QuantiFERON® (or if applicable, T-Spot®) TB test during screening are excluded, unless the patient had previous diagnosis of active or latent TB and has completed appropriate treatment per the discretion of the local investigator within the last 3 years and at the latest at the time of screening (i.e. 2 to 4 weeks before study drug administration); patients may be re-screened once to meet this criterion)
8. History of allergy/hypersensitivity to the systemically administered trial medication agent or its excipients.
9. Any documented active or suspected malignancy or history of malignancy within 5 years prior to screening, except appropriately treated basal or squamous cell carcinoma of the skin or in situ carcinoma of uterine cervix.
10. Women who are pregnant, nursing, or who plan to become pregnant while in the trial. Women who stop nursing before the study drug administration do not need to be excluded from participating; they should refrain from breastfeeding for 16 weeks after the last study drug administration.
11. Major surgery (major according to the investigator’s assessment) performed within 12 weeks prior to receiving first dose of study drug or planned during the study, e.g. hip replacement, aneurynsm removal, stomach ligation, as assessed by the investigator.
12. Evidence of a current or previous disease, medical condition (including chronic alcohol or drug abuse or congestive heart disease or any condition) other than GPP, surgical procedure, psychiatric or social problems, medical examination finding (including vital signs and electrocardiogram (ECG)), or laboratory value at the screening outside the reference range that in the opinion of the investigator is clinically significant.
Additional exclusion criteria will apply. |

E.5 End points |
E.5.1 | Primary end point(s) |
1) Time to first Generalized Pustular Psoriasis (GPP) flare (defined by increase in Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) score by ≥ 2 from baseline and the pustular component of GPPGA ≥ 2) up to week 48. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1) The occurrence of at least one GPP flare (defined by increase in GPPGA score by ≥ 2 from baseline and the pustular component of GPPGA ≥ 2) up to week 48.
2) Time to first worsening of Psoriasis Symptom Scale (PSS) up to week 48 defined as a 4-point increase in total score from baseline. Intake of rescue medication, or investigator-prescribed SoC, will be considered as onset of a worsening.
3) Time to first worsening of Dermatology Quality of Life Index (DLQI) up to week 48 defined as a 4-point increase in total score from baseline. Intake of rescue medication, or investigator-prescribed SoC, will be considered as onset of a worsening.
4) Sustained remission, defined as a patient with a GPPGA score of 0 or 1 (clear or almost clear) at all visits up to week 48, without intake of rescue medication, or investigator-prescribed SoC.
5) The occurrence of treatment emergent adverse events (TEAEs)
