Current Primary Outcome Measures (submitted: November 21, 2023)

Time to First Generalized Pustular Psoriasis (GPP) Flare [ Time Frame: GPPGA was regularly assessed at baseline (Week 1) and up to Week 48 (at Week 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48). Patients could come to site for flare confirmation anytime as unscheduled visit. Visit window was ±7 days. ]

A GPP flare was defined as 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. Use of rescue medication, or investigator-prescribed Standard of Care (SoC) for GPP worsening, was considered to represent a GPP flare onset. GPPGA relied on clinical assessment of the Generalized Pustular Psoriasis (GPP) patient's skin presentation. The GPPGA total score was calculated by taking the mean of the erythema subscore, pustules subscore and scaling/crusting subscore. The severity of each subscore was assessed using a 5 point scale score ranging from 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe). The final GPPGA score is assigned as follows:

• 0 , if scores for all three subscores are 0,
• 1, if 0 < mean < 1.5,
• 2, if 1.5 ≤ mean < 2.5,
• 3, if 2.5 ≤ mean < 3.5,
• 4, if mean ≥ 3.5.

• Original Primary Outcome Measures (submitted: May 20, 2020): Time to first Generalized Pustular Psoriasis (GPP) flare [ Time Frame: up to 48 weeks ]

Current Secondary Outcome Measures (submitted: November 21, 2023)

• Key Secondary Endpoint: The Occurrence of at Least One Generalized Pustular Psoriasis (GPP) Flare up to Week 48 [ Time Frame: GPPGA was regularly assessed at baseline (Week 1) and up to Week 48 (at Week 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48). Patients could come to site for flare confirmation anytime as unscheduled visit. Visit window was ±7 days. ]
  Proportion of patients with at least one GPP flare up to Week 48 is reported. Proportions were rounded up to three decimal places. A GPP flare was defined as increase in Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) score by ≥ 2 from baseline and the pustular component of GPPGA ≥ 2. Any use of rescue medication, or investigator-prescribed SoC for GPP worsening, prior to week 48 was considered to represent the onset of a GPP flare. Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) relied on the clinical assessment of GPP patient's skin presentation. The total score is calculated by taking the mean of the three subscores: 1) erythema; 2) pustules and 3) scaling/crusting which were assessed using a scale score 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe). The final GPPGA score: 0 , if scores for all three subscores are 0,

  1. if 0 < mean < 1.5;
  2. if 1.5 ≤ mean < 2.5;
  3. if 2.5 ≤ mean < 3.5;
  4. if mean ≥ 3.5.
• Time to First Worsening of Psoriasis Symptom Scale (PSS) up to Week 48 [ Time Frame: PSS assessments were performed at: Baseline (Week 1) and up to Week 48 (at Week 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48). Visit window was ±7 days. ]
  Worsening of Psoriasis Symptom Scale (PSS) was defined as a 4-point increase in total score from baseline. Intake of rescue medication, or investigator-prescribed SoC for GPP worsening, was considered as onset of a worsening. The PSS is a 4-item patient-reported outcome (PRO) instrument that was developed to assess the severity of 4 psoriasis symptoms in patients with moderate to severe psoriasis. The symptoms included are: pain, redness, itching, and burning. Current symptom severity is assessed using a 5-point scale ranging from 0 (none) to 4 (very severe). The symptom scores are added to an unweighted total score (range: 0 (no symptoms) to 16 (severe symptoms)).
• Time to First Worsening of Dermatology Quality of Life Index (DLQI) up to Week 48 [ Time Frame: DLQI assessments were performed at: Baseline (Week 1) and up to Week 48 (at Week 4, 8, 12, 24, 36 and 48). Visit window was ±7 days. Time window for Week 48 was from Week 46 to Week 50. ]
  Worsening of DLQI up to week 48 was defined as a 4-point increase in total score from baseline. Intake of rescue medication, or investigator-prescribed SoC for GPP worsening, was considered as onset of a worsening. The DLQI is a patient-administered, ten-question, quality of life questionnaire that covers six domains including symptoms and feelings, daily activities, leisure, work and school, personal relationships and treatment. Response categories include "not relevant" (score of 0), "not at all" (score of 0), "a little" (score of 1), "a lot" (score of 2) and "very much" (score of 3). Question 7 is a "yes"/ "no" question where "yes" is scored as 3. DLQI total score is calculated by summing the scores of each question resulting in a range of 0 (no effect on patient's life) to 30 (extremely large effect on patient's life).
• Sustained Remission [ Time Frame: GPPGA was regularly assessed at baseline (Week 1) and up to Week 48 (at Week 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48). Patients could come to site for flare confirmation anytime as unscheduled visit. Visit window was ±7 days. ]
  Proportion of patients with sustained remission at all visits up to Week 48. Proportions were rounded up to three decimal places. Remission was 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 for GPP worsening. GPPGA relied on clinical assessment of the Generalized Pustular Psoriasis (GPP) patient's skin presentation. The GPPGA total score was calculated by taking the mean of the erythema subscore, pustules subscore and scaling/crusting subscore. The severity of each subscore was assessed using a 5 point scale score ranging from 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe). The final GPPGA score is assigned as follows:

  • 0 , if scores for all three subscores are 0,
  • 1, if 0 < mean < 1.5,
  • 2, if 1.5 ≤ mean < 2.5,
  • 3, if 2.5 ≤ mean < 3.5,
  • 4, if mean ≥ 3.5.
• The Occurrence of Treatment Emergent Adverse Events (TEAEs) [ Time Frame: Up to 62 weeks (for detailed timeframe see description). ]
  Percentage of patients with treatment emergent adverse events (TEAEs) is reported. Percentages were rounded up to one decimal places. Time Frame: Placebo, Spesolimab (Speso) SC low, medium, high: From randomized study treatment start until the first use of rescue medication with IV spesolimab or until last dose + 16 weeks, up to 62 weeks. Speso IV SD and Speso IV DD: From first use of rescue medication with IV spesolimab until OL maintenance spesolimab SC or until last dose of spesolimab IV + 16 weeks, up to 17 weeks. Speso OL SC: From the first dose of OL spesolimab SC treatment until last dose + 16 weeks, up to 62 weeks.

• Official Title: Effisayil™ 2: Multi-center, Randomized, Parallel Group, Double Blind, Placebo Controlled, Phase IIb Dose-finding Study to Evaluate Efficacy and Safety of BI 655130 (Spesolimab) Compared to Placebo in Preventing Generalized Pustular Psoriasis (GPP) Flares in Patients With History of GPP.

Brief Summary

This is a study in adolescents and adults with Generalized Pustular Psoriasis (GPP). People between 12 and 75 years old can take part in the study. The study is open to people who had GPP flare-ups in the past but whose skin is clear or almost clear when they join the study. The purpose of the study is to test 3 different doses of a medicine called spesolimab and to see whether it helps to prevent GPP flare-ups.

Participants are put into 4 groups by chance. Three groups get different doses of spesolimab. The fourth group gets a placebo. Placebo looks like spesolimab but does not contain any medicine.

Spesolimab and placebo are given as an injection under the skin. Participants are in the study for about 1 year and 4 months. During this time, they visit the study site about 15 times. For the first 11 months, participants get spesolimab or placebo injections every month. At the study visits, the doctors check participants' skin for signs of a new GPP flare-up. The doctors also check the general health of the participants.

If a participant has a GPP flare-up during the study, more visits may be necessary. In case of a flare-up, participants get a dose of spesolimab as an infusion into a vein.
