Outcomes

Primary Outcomes

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.

Time frame: At Week 1.

Secondary Outcomes

Key Secondary: Proportion of Patients With a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) Score of 0 or 1 at Week 1

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. A lower GPPGA score indicates a better outcome, with 0 being clear and 1 being almost clear. The proportion of patients with a GPPGA score of 0 or 1 at Week 1 is reported.

Time frame: At Week 1.

Proportion of Patients With a Psoriasis Area and Severity Index for Generalized Pustular Psoriasis (GPPASI) 75 at Week 4

Generalized Pustular Psoriasis Area and Severity Index (GPPASI) provides a numeric scoring for a patient's overall Generalized Pustular Psoriasis (GPP) disease state, ranging from 0 to 72. It is a linear combination of percent of surface area of skin affected by erythema, pustules, and scaling and the severity of erythema, pustules, and scaling (desquamation) over 4 body regions (head, trunk, upper limbs and lower limbs). A higher score indicates a worse disease state, while a score of 0 indicates no disease. GPPASI 75 is based on the percent reduction from baseline, generally summarized as a dichotomous outcome based on achieving over an 75% reduction. Proportion of patients with GPPASI 75 at Week 4 is reported.

Change From Baseline in Pain Visual Analog Scale (VAS) Score at Week 4

The pain Visual Analogue Scale (VAS) is a participant-administered single-item scale designed to measure skin pain intensity from generalized pustular psoriasis (GPP) using a 100 millimeter (mm) horizontal VAS. Overall severity of participant's skin pain from GPP is indicated by placing a single mark on the horizontal 100 mm scale from 0 mm (no pain) to 100 mm (pain as bad as one can imagine). Change from baseline was calculated by subtracting the VAS score at baseline from the VAS score at Week 4. A negative change indicates an improvement from baseline. Death, any use of escape medication, OL Spesolimab at Day 8, or rescue medication with Spesolimab after Day 8, prior to observing the endpoint was considered to reflect a failure to achieve the endpoint outcome, i.e. non-response (NR). NR is not a missing value but the worst possible outcome of the endpoint. For example, if the achieved data is (NR, NR, NR, NR, NR, NR, 2, 3, 3, 3, 5) then Q1 is NR, median is NR and Q3 is 3.

Time frame: Baseline and at Week 4.

Change From Baseline in Psoriasis Symptom Scale (PSS) Score at Week 4

PSS is a 4-item patient-reported outcome instrument that assesses the severity of psoriasis symptoms in moderate to severe psoriasis patients. The symptoms included are: pain, redness, itching, and burning. The symptom severity was assessed using a 5 point scale ranging from 0 to 4 where 0=none, 1=mild, 2=moderate, 3=severe, 4=very severe. The symptom scores are added to an unweighted total score (range: 0 to 16). A lower PSS score indicates a better outcome. Change from baseline =PSS score at Week 4 - PSS score at baseline. Death, any use of escape medication, OL Spesolimab at Day 8, or rescue medication with Spesolimab after Day 8, prior to observing the endpoint was considered to reflect a failure to achieve the endpoint outcome, i.e. non-response (NR). NR is not a missing value but the worst possible outcome of the endpoint. For example, if the achieved data is (NR, NR, NR, NR, NR, NR, 2, 3, 3, 3, 5) then Q1 is NR, median is NR and Q3 is 3.

Time frame: Baseline and at Week 4.

Change From Baseline in Functional Assessment of Chronic Illness Therapy (FACIT) - Fatigue Score at Week 4

The FACIT-Fatigue is a 13-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function. Each items is scored from 0 to 4. Score range is 0 (extreme fatigue)-52 (no fatigue). Change from baseline=FACIT Fatigue score at Week 4- FACIT-Fatigue score at baseline. Death, any use of escape medication, OL Spesolimab at Day 8, or rescue medication with Spesolimab after Day 8, prior to observing the endpoint was considered to reflect a failure to achieve the endpoint outcome, i.e. non-response (NR). NR is not a missing value but the worst possible outcome of the endpoint. For example, if the achieved data is s (NR, NR, NR, NR, NR, NR, 2, 3, 3, 3, 5) then Q1 is NR, median is NR and Q3 is 3.

Time frame: Baseline and at Week 4.

Proportion of Patients With a Generalized Pustular Psoriasis Physician Global Assessment (GPPGA) Score of 0 or 1 at Week 4

GPPGA relied on clinical assessment of the Generalized Pustular Psoriasis (GPP) patient's skin presentation. The GPPGA total score is 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 scores 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. A lower GPPGA score indicates a better outcome, with 0 being clear and 1 being almost clear. The proportion of participants with a GPPGA score of 0 or 1 at Week 4 is reported.

Proportion of Patients With a Generalized Pustular Psoriasis Area and Severity Index (GPPASI) 50 at Week 4

Generalized Pustular Psoriasis Area and Severity Index (GPPASI) provides a numeric scoring for a patient's overall Generalized Pustular Psoriasis (GPP) disease state, ranging from 0 to 72. It is a linear combination of percent of surface area of skin affected by erythema, pustules, and scaling and the severity of erythema, pustules, and scaling (desquamation) over 4 body regions (head, trunk, upper limbs and lower limbs). A higher score indicates a worse disease state, while a score of 0 indicates no disease. GPPASI 50 is based on the percent reduction from baseline, generally summarized as a dichotomous outcome based on achieving over an 50 % reduction. Proportion of patients with GPPASI 50 at Week 4 is reported.

Time frame: At Week 4.

Percent Change in Generalized Pustular Psoriasis Area and Severity Index (GPPASI) From Baseline at Week 4

GPPASI provides a numeric scoring for a patient's overall Generalized Pustular Psoriasis (GPP) disease state, ranging from 0 (no disease) to 72 (worse disease state). It is a linear combination of percent of surface area of skin affected by erythema, pustules, and scaling and the severity of erythema, pustules, and scaling (desquamation) over 4 body regions (head, trunk, upper limbs and lower limbs). %GPPASI change from baseline=(GPPASI at Week 4-GPPASI at baseline) \*100/(GPPASI at baseline). Death, any use of escape medication, OL Spesolimab at Day 8, or rescue medication with Spesolimab after Day 8, prior to observing the endpoint was considered to reflect a failure to achieve the endpoint outcome, i.e. non-response (NR).NR is not a missing value but the worst possible outcome of the endpoint. For example, if the achieved data is (NR, NR, NR, NR, NR, NR, 2, 3, 3, 3, 5) then Q1 is NR, median is NR and Q3 is 3. Planned statistical analysis were not performed due to lack of valid data.

Time frame: Baseline and at Week 4.

Proportion of Patients With a Generalized Pustular Psoriasis Area and Severity Index (GPPASI) 50 at Week 1

Generalized Pustular Psoriasis Area and Severity Index (GPPASI) provides a numeric scoring for a patient's overall Generalized Pustular Psoriasis (GPP) disease state, ranging from 0 to 72. It is a linear combination of percent of surface area of skin affected by erythema, pustules, and scaling and the severity of erythema, pustules, and scaling (desquamation) over 4 body regions (head, trunk, upper limbs and lower limbs). A higher score indicates a worse disease state, while a score of 0 indicates no disease. GPPASI 50 is based on the percent reduction from baseline, generally summarized as a dichotomous outcome based on achieving over an 50 % reduction. Proportion of patients with GPPASI 50 at Week 1 is reported.

Percent Change in Generalized Pustular Psoriasis Area and Severity Index (GPPASI) From Baseline at Week 1

Generalized Pustular Psoriasis Area and Severity Index (GPPASI) provides a numeric scoring for a patient's overall Generalized Pustular Psoriasis (GPP) disease state, ranging from 0 to 72. It is a linear combination of percent of surface area of skin affected by erythema, pustules, and scaling and the severity of erythema, pustules, and scaling (desquamation) over 4 body regions (head, trunk, upper limbs and lower limbs). A higher score indicates a worse disease state, while a score of 0 indicates no disease. The percent change from baseline at Week 1 is calculated as: % GPPASI change from baseline = (GPPASI at Week 1 - GPPASI at baseline) \*100/GPPASI at baseline. If % GPPASI change from baseline is positive, it means the disease is becoming worse.

Time frame: At Week 1.

Occurrence of Treatment Emergent Adverse Events (TEAEs) up to Week 1

TEAEs were all Adverse Events (AEs) occurring between start of treatment and Day 8 (Day 8 excluded). AEs that started before first drug intake and deteriorated under treatment were also considered as 'treatment-emergent'. The exposure-adjusted incidence rate was calculated as: Incidence rate \[1/100 patients-years\] = 100 × number of patients with AE / Total AE specific time at risk \[patient-years\] where: Time at risk \[patient-years\] = (date of onset of TEAE - study drug start date + 1) /365.25

Time frame: From start of treatment until Day 7, up to 7 days.
