The number and percentage of participants with treatment emergent AEs/SAEs will be summarized. No hypothesis testing will be performed.

Sustained remission at Week 52 is defined as a participant meeting all of the following: ● achieved remission at Week 12 AND all of the following, sustained from Week 12 to Week 52: * no recurrence of signs or symptoms, attributable to PMR, that requires escape treatment or rescue treatment * no new diagnosis of Giant cell arteritis (GCA), that requires escape treatment or rescue treatment Remission at Week 12 is defined as a participant meeting all of the following at Week 12: * no use of escape treatment or rescue treatment prior to Week 12 * no signs or symptoms attributable to PMR, that requires escape treatment or use of rescue treatment, at Week 12 * no new diagnosis of GCA, that requires escape treatment or rescue treatment, at Week 12

The WORC Index consisted of 21 items divided into 5 Domains: Physical Symptoms (6 items), Sport/Recreation (4 items), Work Function (4 items), Lifestyle Function (4 items) and Emotional Function (3 items). Each of the 21 items in the WORC was rated using a visual analogue scale (VAS) ranging from 0 (no impact on quality of life) to 100 (worst possible impact). Thus, the total score ranged from 0 to 2100 points. The score was reported as a percentage of normal by subtracting the total score from 2100, dividing by 2100, and multiplying by 100. Total final WORC percentage scores ranged from 0%, the lowest functional status level, to 100%, the highest functional status level. Change from baseline in the WORC percentage total score was assessed at Week 24. A positive change from baseline indicated an improvement.

To demonstrate the superiority of secukinumab 300 mg s.c. compared to placebo (both arms in combination with a prednisolone or equivalent taper regimen as per treatment guideline) in delaying the time to first GCA clinical relapse from baseline in participants with new onset of GCA who are in clinical remission and eligible for treatment with glucocorticoid-monotherapy. GCA clinical relapse is defined as both: 1. The recurrence of signs or symptoms attributable to active GCA after clinical remission, which are considered clinically significant by the investigator AND 2. The requirement of a change in the treatment prompted by the recurrence of signs and symptoms i. an increase in prednisolone or equivalent dose AND/OR ii. the addition of a rescue treatment. Definition of clinical remission: absence of signs and symptoms attributable to active GCA as determined by the investigator.

Primary objective is to determine whether the efficacy of secukinumab 300 mg s.c. in combination with a 26-week GC taper regimen is superior to placebo in combination with a 52-week glucocorticoids (GC) taper regimen in participants with giant cell arteritis (GCA) based on sustained remission at Week 52

ASAS40 response was defined as relative improvement of at least 40% and absolute improvement of at least 2 units on a 0 to 10 scale in at least 3 of the 4 main domains of the ASAS and no worsening at all in the remaining domain. The 4 main domains of the ASAS are: 1.Patient's Global Assessment of Disease Activity (score ranged from 0 \[not active\] to 10 \[very active\]); 2.Back Pain (score ranged from 0 \[no pain\] to 10 \[severe pain\]); 3.Function (Bath Ankylosing Spondylitis Functional Index \[BASFI\]) (score ranged from 0 \[easy\] to 10 \[impossible\]); 4.Inflammation (mean of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) questions 5 and 6 concerning morning stiffness intensity and duration) (score ranged from 0 \[none\] to 10 \[very severe\]). The percentage of TNF-alpha-inhibitor-naïve participants who achieved ASAS40 response at Week 16 was assessed using a logistic regression model. Discontinued participants and those with missing responses were considered non-responders

The disability assessment component of the HAQ evaluated a subject's level of functional ability through 20 questions grouped into 8 categories: dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. Each item began with the prompt "Over the past week, are you able to…" and is scored on a 4-point scale: 0 (no difficulty), 1 (some difficulty), 2 (much difficulty), and 3 (unable to do). The overall score was calculated by averaging the scores across all answered domains, resulting in a total score ranging from 0 (no disability) to 3 (severe disability). A HAQ-DI response was defined as an improvement of ≥0.35 points from baseline at Week 28. Missing values were imputed as non-responders

Loss of response was defined as: * at least a 50% increase in abscess and/or nodules (AN) count compared to the average AN count from the 3 previous visits or at Week 52, whichever is lower and the increase was at least of 3 AN. * at least a 30% increase in AN compared to the average AN count from the 3 previous visits or Week 52, whichever is lower, with an increase of at least 2 AN and a further increase in the AN count of at least 2 AN at a re-assessment visit within 2-4 weeks

The incidence rate of participants achieving Loss of Response (LOR) was based on the primary estimand. * Day 1 = Date of 1st dose intake in the extension study. * Subjects at risk = Subjects who did not have LOR and were not censored before or at the start of the specified time interval. * Incidence rate (%) = (number of subjects with LOR / number of subjects at risk) x 100.

ASAS40 is ≥ 40% and an absolute improvement from baseline of ≥20 units (range 0-100) in ≥ 3 of the following 4 domains: back pain \[10 cm visual analogue scale (VAS)\], patient global assessment of disease activity (10 cm VAS), physical function (BASFI; range 0-100) and inflammation (mean score of items 5 and 6 of the BASDAI; both 10 cm VAS) without any worsening in the remaining domain.

The total score was calculated as the average of the scores for each domain. It ranged from 0 (no disability) to 3 (very severe disability). * Number of joints with active arthritis (as per ACR definition), ranging from 0 to 73. * Number of joints with limited range of motion, ranging from 0 to 69. * Index of inflammation: C-reactive Protein (CRP) levels The JIA ACR 30 response was achieved if 3 of any 6 core set variables improved by at least 30% from baseline of the core study, and no more than 1 variable worsening more than 30%

HiSCR50 at Week 16 is defined as at least a 50% decrease in Abscess and inflammatory Nodule (AN) count compared to baseline with no increase in the number of abscesses and/or in the number of draining fistulas from baseline to Week 16. The baseline is defined as the last assessment (including unscheduled visits) obtained before/on the day of the first administration of the study treatment, or on the randomization date if there had been no drug administration. This endpoint was analyzed by logistic regression.

Number (%) of patients with resolution of Achilles tendon enthesitis (affected foot) as assessed by respective subcomponent of Leeds enthesitis index (LEI) at Week 24. The primary analysis was performed via a logistic regression model with the factors treatment, country, and stratification factor diagnosis (PsA or axSpA); patients with a missing assessment were considered as responders if they had already met the response criterion at the time of last assessment.

Number of participants who achieved ≥ 90% reduction in PASI compared to baseline. Logistic regression analysis of PASI 90 response at Week 12 PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72 (maximal disease). Body is divided into 4 areas for scoring (head, upper limbs, trunk, lower limbs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of body region(head: 0.1, upper limbs: 0.2, trunk: 0.3, lower limbs: 0.4).

Investigator's Global Assessment uses a scale (IGA mod 2011) that rates disease from a score of 0 (clear skin) to 4 (severe disease)

PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72(maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section (head: 0.1, arms: 0.2 body: 0.3 legs: 0.4).

PASI (Langley et al 2015) combines the assessment of the severity of lesions and the area affected into a single score with a range of 0 (no disease) to 72 (maximal disease). The PASI was assessed at all visits in CORE and extension phases. PASI 90 response: patients achieving ≥ 90% improvement (reduction) in PASI score compared to baseline are defined as PASI 90 responders.

PASI score is an average degree of severity of signs in head \[H\], trunk \[T\], upper limbs \[U\] and lower limbs \[L\], assessed separately for erythema \[E\], thickening (plaque elevation, induration) \[I\], and scaling (desquamation) \[D\]. Area \[A\] covered by lesions on each body region was estimated as a percentage (%) of total area of that particular body region and was assigned a score of 0=0%; 1=1-9%; 2=10-29%; 3=30-49%; 4=50-69%; 5=70-89%; 6=90-100%. The head and neck, upper limbs, trunk and lower limbs correspond to approximately 10%, 20%, 30% and 40% of the body surface area, respectively. PASI score was calculated as: PASI = 0.1(EH+IH+DH) AH + 0.2(EU+IU+DU) AU + 0.3(ET+IT+DT) AT + 0.4(EL+IL+DL) AL. PASI scores can range from 0 (no signs) to a maximum of 72.0. PASI 75 responders were participants who achieved \>=75% improvement (reduction) in PASI score compared to baseline.

The primary endpoint was assessed by the palmoplantar pustulosis Psoriasis Area and Severity Index 75 (ppPASI 75). The percentage of subjects who achieved a 75% reduction in ppPASI score from Baseline to Week 16 was measured. The ppPASI is a modification of the PASI score and adjusted for palmoplantar pustular psoriasis by classifying and scoring erythema, scaling (desquamation) and pustules/vesicles. Both palms and both plants are scored from 0 to 4. The extent of involvement of each region of the body is scored from 0 to 6. The total ppPASI score can range from a lower level of 0, corresponding to no signs of psoriasis, up to a maximum of 72.

The NAPSI is a tool to assess psoriatic nail involvement in patients with nail psoriasis. Each nail is divided with imaginary horizontal and longitudinal lines into quadrants. Each nail is given a score for nail matrix psoriasis (0-4) and nail bed psoriasis (0-4) depending on the presence of any of the features of nail psoriasis in that quadrant. Each nail gets a nail matrix score and a nail bed score, the total of which is the NAPSI score for that nail ranging from 0 to 8. All 10 fingernails are assessed giving a total NAPSI score ranging from 0 to 80. A negative change from baseline indicates improvement. The adjusted mean is presented.

palmoplantar Investigator's Global Assessment (ppIGA) response after 16 weeks of treatment. To be considered a ppIGA responder at Week 16, a subject must have ppIGA of 0 or 1 at Week 16 and a reduction of at least 2 points on the ppIGA scale from baseline.

ACR20 response was defined as having a positive clinical response to treatment (individual improvement) in disease activity if the participant had at least 20% improvement in tender 68-joint count, swollen 66-joint count and at least 3 of the following 5 measures: patient's assessment of RA pain, patient's global assessment of disease activity, physician's global assessment of disease activity, subject self-assessed disability (Health Assessment Questionnaire \[HAQ-DI\] score), and/or acute phase reactant (high sensitivity c-reactive protein (hsCRP) or erythrocyte sedimentation rate (ESR). For subjects with early escape at Week 16 or had missing values at Week 24 or discontinued prior to Week 24, their ACR20 was set to nonresponse at Week 24. This applied for all treatment regimens in order to minimize bias. The Placebo arm was analyzed as one group, irrespective of the re-randomization, as assessments made under the re-randomized active treatment were not included in this analysis.

ASAS 20 response is a validated composite assessment reflecting the percentage of treated patients who achieve within a defined timeframe an improvement of 20% and ≥1 unit on a scale of 1 to 10 in at least three of the four ASAS main domains and no worsening of ≥20% and ≥1 unit in the remaining domain. ASAS 20 is used to assess the efficacy of at least one dose of secukinumab against placebo.

Efficacy of secukinumab compared to placebo in subjects with moderate to severe chronic plaque-type psoriasis. PASI score was based on assessment of the head, trunk, upper limbs and lower limbs for erythema, thickening (plaque elevation, induration), and scaling (desquamation). PASI scores can range from 0, corresponding to no signs of psoriasis, up to a theoretical maximum of 72.0. PASI-based secondary variables included absolute PASI score, response rates for PASI 75. PASI 50 and PASI 90 were defined as ≥ 50% and ≥ 90% improvement from Baseline in PASI score, respectively, while PASI 100 response corresponded to complete clearing of psoriasis (PASI = 0). IGA mod 2011 was used to evaluate the overall severity of psoriatic disease, with scores ranging from 0 (clear) to 4 (severe). Treatment success was defined as achievement of IGA mod 2011 0 or 1 score.

The primary variable was the cumulative rate of patients who lost PASI 75 response up to Week 68 (time=0 being defined as Week 52). Loss of PASI 75 response was analyzed by means of a survival analysis defining "loss of PASI 75 response" as "failure". The term cumulative rate corresponded to 1 minus the survival function within this survival analysis, and the cumulative rate and the survival functions were dependent on time t. PASI 75 response: patients achieving ≥ 75% improvement (reduction) in PASI score compared to baseline of the core study were defined as PASI 75 responders.

A 75% reduction in the Psoriasis Area and Severity Index (PASI) score (PASI 75) is the current benchmark of primary endpoints for most clinical trials of psoriasis

The IGA scale has been developed based on a previous version of the scale used in secukinumab phase II studies in collaboration with health authorities, in particular the FDA. The explanations/descriptions of the points on the scale have been improved to ensure appropriate differentiation between the points. The IGA used in this study is static, i.e. it refers exclusively to the subject's disease state at the time of the assessments, and does not attempt a comparison with any of the subject's previous disease states, whether at baseline or at a previous visit. IGA has a scale of 0-4 with the lower scores correlating to better performance. A score of 0= clear skin, 1= almost clear skin, 2=mild, 3=moderate,4=severe

PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72(maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section (head: 0.1, arms: 0.2 body: 0.3 legs: 0.4).

The IGA mod 2011 scale is static, i.e. it referred exclusively to the participant's disease at the time of the assessment, and did not compare with any of the participant's previous disease states at previous visits. The scores are: 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. Treatment success was defined as achievement of IGA mod 2001 score of 0 or 1.

ASAS 20 response is a validated composite assessment, reflecting the proportion of treated patients who achieve within a defined timeframe at least 20% improvement in score in at least 3 of a conventional set of 4 clinical domains relevent to AS and no worsening in the fourth domain.

The ACR20 response results at week 24 used non-responder imputation.

A 75% reduction in the Psoriasis Area and Severity Index (PASI) score (PASI 75) is the current benchmark of primary endpoints for most clinical trials of psoriasis. PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72(maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section (head: 0.1, arms: 0.2 body: 0.3 legs: 0.4).

The IGA mod 2011 scale is static, i.e. it referred exclusively to the participant's disease at the time of the assessment, and did not compare with any of the participant's previous disease states at previous visits. The scores are: 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe. Treatment success was defined as achievement of IGA mod 2001 score of 0 or 1. IGA score of 0 or 1 as an indicator of efficacy.

A 75% reduction in the Psoriasis Area and Severity Index (PASI) score (PASI 75) is the current benchmark of primary endpoints for most clinical trials of psoriasis

The IGA mod 2011 scale has been developed based on a previous version of the scale used in secukinumab phase II studies in collaboration with health authorities, in particular the FDA. The explanations/descriptions of the points on the scale have been improved to ensure appropriate differentiation between the points. The IGA mod 2011 used in this study is static, i.e. it refers exclusively to the subject's disease state at the time of the assessments, and does not attempt a comparison with any of the subject's previous disease states, whether at baseline or at a previous visit.IGA mod 2011 has a scale of 0-4 with the lower scores correlating to better performance. A score of 0= clear skin, 1= almost clear skin, 2=mild, 3=moderate,4=severe.

Remission was defined as the absence of flare. Sustained remission was defined as the absence of flare until Week 28 and in adherence to the protocol prednisolone taper regimen. Flare was determined by the investigator and was defined as the recurrence after remission of signs or symptoms of Giant Cell Arteritis (GCA) and/or erythrocyte sedimentation rate (ESR) greater than or equal to (\>/=) 30 millimeters per hour (mm/hr) and/or C-reactive Protein (CRP) (\>/=10.0 mg/L) attributable to GCA. Patients were classified as non-responders if they did not achieve remission within 12 weeks of Baseline (remission referred to the absence of flare), were in the "escape arm" (this referred to patients entering escape between Baseline and Week 28), prematurely discontinued study treatment prior to Week 28 (absence of flare was checked prior to study treatment administration), did not have information to evaluate sustained remission response until Week 28.

WORC PRO score at week 14. The WORC Index consists of 21 items divided into 5 Domains: Physical Symptoms (6 items), Sport/Recreation (4 items), Work Function (4 items), Lifestyle Function (4 items) and Emotional Function (3 items). The total scores and sub scores used were the percentages of the normal scores with 0 being worst and 100 being best. All Patients - Statistical analysis results of WORC scores at Week 14

Neutrophil apoptosis will be measured using flow-cytometry.

Neutrophil phenotype will be determine as percent of receptor expressing cells assessed by flow cytometry

Histological sections of lesional and nonlesional skin biopsies at baseline and at Week 12 were examined. For each visit, each patient's lesional skin biopsy was scored for the degree of histological improvement compared to that patient's baseline disease on a five point scale; - 1 (worse) to +3 (excellent). Histological disease reversal or "excellent improvement" (histological disease reversal score = 3) was declared at the endpoint when all of the following four criteria were met.

A participant was considered to be a responder according to the ACR20 criteria if the participant had at least 20% improvement in both the tender joint count and swollen joint count measures, and in at least 3 of the following 5 measures: patient's assessment of pain, patient's global assessment of disease activity, physician's global assessment of disease activity, Health Assessment Questionnaire (HAQ©) score, and/or C-reactive protein (CRP)/Erythrocyte Sedimentation Rate (ESR).

A participant was considered to be a responder according to the ACR20 criteria if the participant had at least 20% improvement in both the tender joint count and swollen joint count measures, and in at least 3 of the following 5 measures: patient's assessment of pain, patient's global assessment of disease activity, physician's global assessment of disease activity, Health Assessment Questionnaire (HAQ©) score, and/or C-reactive protein (CRP)/Erythrocyte Sedimentation Rate (ESR).

The DAS28 is a measure of disease activity in RA. The score is calculated by a complex mathematical formula, which includes the tender joint count(TJC) and swollen joint count (SJC) out of a total of 28 joints, the high-sensitivity C-reactive protein (hsCRP), and the subject's 'global assessment' of disease activity/general health (GH). The subject's global assessment/GH was indicated by a visual analogue scale of 100 mm where the participant marked a point on a 100 mm line between 0 and 100 (0 indicated very good and 100 indicated very bad). The following formula was used to calculate DAS28: DAS-CRP = 0.56\*sqrt(TJC28) + 0.28\*sqrt(SJC28) = 0.36\*ln(CRP+1) + 0.014\*GH = 0.96. A DAS28-CRP score \> 5.1 implies active disease, \<3.2 implies controlled disease and \<2.6 implied remission. A negative change from baseline indicates improvement.
