Clinical Trial Summary

This was an open-label, parallel-group, two-arm, multicenter study in pediatric subjects aged 6 years to less than 18 years, at randomization, with moderate to severe chronic plaque psoriasis. 84 subjects (most with moderate severity) were enrolled. Subjects were stratified by weight and disease severity.

Description:

This was an open-label, parallel group, two-arm, multi-center, trial in pediatric subjects aged 6 years to less than 18 years, at randomization, with moderate to severe chronic, plaque psoriasis. The study consists of 3 periods: screening (up to 4 weeks), treatment (Week 208) and post-treatment follow-up (Week 224). Approximately 80 subjects (at least 60 subjects with moderate psoriasis) were planned to be enrolled in about 40 centers worldwide and targeted to have at least 5 subjects in the < 25kg body weight, and at least 10 subjects in each of the other two weight groups (25-< 50 kg and ≥ 50 kg). Adolescents (12-< 18 years) and children (6-< 12 years) were included from the beginning of this study, since the DMC had approved already the enrollment of children (6-< 12 years) in the study CAIN457A2310 (NCT02471144). Subjects received the appropriate dose based on their body weight category. For the statistical analysis for outcome measures 1 and 2, there was no 'within study' control arm. A historical placebo control was obtained using data from qualifying trials and used as the comparator for the primary and key secondary endpoint analysis. This was in line with the guidance from and discussions with Health Authorities including FDA and EMA (PDCO), which suggested reducing placebo exposure as well as overall clinical trial burden for the pediatric population and accepted an extrapolation approach (EMA 2012). Historical placebo data included in this study were based on clinical appropriateness and alignment of definitions (endpoints, clinical disease population and time point of assessment). Integrated in the analysis were placebo data from Novartis-reported secukinumab adult placebo-controlled studies (CAIN457A2302 (NCT01544595 and NCT01365455), CAIN457A2303 (NCT01544595 and NCT01358578), CAIN457A2308 (NCT01555125) and CAIN457A2309 (NCT01636687)) and pediatric placebo-controlled study CAIN457A2310. In addition, pediatric placebo-controlled study data from the literature on other biologics (e.g. etanercept, ustekinumab) were utilized (Paller et al 2008, Landells et al 2015). If the subject moved into a higher or lower weight group at two consecutive visits with weight measurements during the maintenance (from Week 12 onwards as assessed at 4 weekly visits or during extension treatment period (as assessed at scheduled site visits), then the subject was dosed according to the new (higher or lower) weight group respectively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number and Percentage of Participants With PASI 75 Response	Psoriasis Area and Severity Index (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, trunk, upper limbs and 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,Thickening (plaque elevation, induration) & Scaling(desquamation). Scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area* area score weight of section(head: 0.1, upper limbs: 0.2 body: 0.3 lower limbs: 0.4). Psoriasis Area and Severity Index (PASI) will be assessed/calculated as per standard procedure. PASI 75 represents the percentage (or number)of patients who have achieved a 75% or more reduction in their PASI score from baseline. PASI 100 indicates patients who have achieved a complete resolution of all disease.	Week 12
Primary	Number and Percentage of Participants With IGA Mod 2011 0 or 1 Response	Investigator will assess the disease using the validated Investigator Global Assessment (IGA) mod 2011 and rate the disease from a score of 0 (clear skin) to 4 (severe disease)	Week 12
Secondary	Number and Percentage of Participants With PASI 90 Response	Psoriasis Area and Severity Index (PASI) was assessed/calculated as per the standard procedure.; PASI 90 represents the percentage (or number) of patients who have achieved a 90% or more reduction in their PASI score from baseline. PASI 100 indicates patients who have achieved a complete resolution of all disease.	Week 12
Secondary	Secukinumab Concentration in Serum	Mean (Standard Deviation) Secukinumab concentration levels in serum over time.	Baleine, Weeks 4, 12, 13, 14, 15, 16, 24, 52, 104, 156, 208
Secondary	Summary Table of Adverse Events	An adverse event (AE) is any untoward medical occurrence (e.g. any unfavorable and unintended sign [including abnormal laboratory findings], symptom or disease) in a clinical investigation participant after providing written informed consent for participation in the study.; Treatment emergent adverse events in this study are events that started after the first dose of study treatment and until 84 days after the last study treatment, or events present prior to the first dose of treatment which increased in severity based on preferred term within 84 days after the last study treatment.	Adverse events are reported from the first dose of study-drug until the end of the treatment period (at Week 208) plus 16 weeks additional follow up reporting, for a maximum timeframe of approximately 224 weeks.
