Analysis of absolute and relative frequencies for treatment emergent Adverse Event (AE), Serious Adverse Event (SAE) and Deaths by primary System Organ Class (SOC)

Safety Set. All subjects who took at least one dose of study treatment during the extension treatment period. A subject with multiple adverse events within a primary system organ class was counted only once in the total row. Deaths up to 28 days after the last dose are included. Only descriptive analysis done.

PASI: 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 full analysis set (FAS), which consisted of all participants with an observed value, was considered. Only patients with evaluable data at each time point were analyzed for that time point. Only descriptive analysis done.

The IGA mod 2011 is a static scale, i.e., it refers exclusively to the participant's disease state at the time of the assessments and does not attempt a comparison to any of the participant's previous disease states at prior visits. The score ranges from 0 (clear) to 4 (severe). The score 0 is clear, 1 is almost clear, 2 is mild, 3 is moderate, and 4 is severe.

The DLQI is a quality of life measure used in the psoriatic The 10-item questionnaire has a score range of 0 (best) to 30 (worst) with higher scores indicating poor quality of life. The instrument contains six functional scales (i.e., symptoms and feeling, daily activities, leisure, work and school, personal relationships, treatment). Each item has 4 response categories, ranging from 0 (not at all) to 3 (very much). "Not relevant" is also a valid response and is scored as 0. The DLQI total score is a sum of the 10 questions

ED-5Q: Participant rated questionnaire to assess health related quality of life in terms of a single utility score. Five domains are assessed mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) each with three possible score: 1 indicates no problems, better state of health; 3 indicates worst state of health (example "confined to bed") A visual analog scale (VAS) assesses the health status from 0 (worst possible health state) to 100 (best possible health state)

The development of anti-secunimubab anti-bodies will decrease a participant's ability to respond to secukinumab treatment.

Relapse is defined as greater than 50% loss of the maximal PASI improvement from baseline.

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). A negative mean percentage change indicates improvement.

Rebound of disease is defined as a worsening of PASI of > 125% of the value at baseline (core study), or new pustular, erythrodermic or more inflammatory psoriasis occurring within 8 weeks of stopping therapy (i.e., if this definition was fulfilled at more than 8 weeks after last study treatment administration, this was defined as rebound like event).
