Clinical Trial Summary

This was a multicenter, randomized, double-blind, placebo- and active-controlled (etanercept in single blinded arm) study in pediatric subjects aged 6 years to less than 18 years with severe chronic plaque psoriasis. Approximately 160 subjects aged 6 years to <18 years were enrolled, of which at least 30 were 6 years to <12 years old. Subjects were enrolled at approximately 70 study sites worldwide.

Description:

The purpose of this study was to demonstrate superior efficacy of secukinumab versus placebo at Week 12, based on both PASI 75 and IGA mod 2011 0 or 1 response rates in children and adolescents aged 6 to less than 18 years with severe chronic plaque psoriasis who had inadequate control of symptoms with topical treatment, or failed to respond to or tolerate previous systemic treatment and/or UV therapy The study assessed the long term safety and tolerability of secukinumab in this pediatric age group and described the efficacy and safety of secukinumab compared to etanercept. This study provided efficacy and safety data to support the extension of label of secukinumab to include children and adolescents (6 years to <18 years) with severe chronic plaque psoriasis Two age subgroups were studied in a staggered approach within this clinical study: 12 to less than 18 years of age, and 6 to less than 12 years of age . Enrolment of children aged 6 to less than 12 years began after a favorable recommendation by an independent external Data Monitoring Committee (DMC) who reviewed data of approximately 80 adolescents. Adolescents continued to be recruited while the data from the first 80 subjects was being collected and analyzed Subjects were randomized using a 1:1:1:1 ratio into one of the treatment arms: secukinumab low dose, secukinumab high dose, etanercept or placebo. Subjects randomized to secukinumab treatment arms (high dose and low dose) received dose based on the weight category (<25 kg, 25 to <50kg, ≥50 kg). The study consisted of 5 periods: screening (up to 4 weeks), induction (of 12 weeks), maintenance (of 40 weeks), extension treatment epoch (open-label of 184 weeks) and post- treatment follow-up epoch (of 16 weeks). The screening period of up to 4 weeks was used to assess eligibility of the patients and to taper patients off prohibited medications. The Induction period is defined as randomization through Week 12. In this period, the study was both active and placebo-controlled and at its completion, the primary endpoint was assessed (Week 12). The Maintenance period is defined as Week 12 (from dosing) through Week 52. During this period, the study was active-controlled, and the objectives focused on the maintenance of the response observed at Week 12. Patients who received secukinumab or etanercept during induction continued in maintenance with the same treatment. Patients who were on placebo during induction and at Week 12 were PASI 75 non-responders were switched to either secukinumab low dose or secukinumab high dose treatment group in the Maintenance period according to their baseline randomization. At the end of the Maintenance period, all patients on secukinumab entered the Extension treatment period and continued to receive the same dose of secukinumab. The Extension treatment period was defined as Week 52 (from dosing) until Week 236. In this period, all patients were treated with secukinumab, and the purpose was the collection of long-term safety and efficacy data. Patients who participated in the Maintenance period but prematurely discontinued the study were not able to enter the Extension treatment period. Patients receiving etanercept were not eligible to enter the Extension treatment period. Instead, at Week 52, they completed an EOM visit and then entered the post-treatment Follow-up period.

Depending on weight group subject will receive per dose a) 75 mg if weighing less than 50 kg b) 150 mg if weighing 50 kg or more. Secukinumab injections (one or two per dose, depending on the weight group) will be administered subcutaneously at Randomization, Weeks 1, 2, 3, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48, and Placebo secukinumab at Weeks 13, 14 and 15 during the blinded phase of the study; thereafter at Week 52 and every 4 weeks during the extension treatment period until Week 232.
• Experimental: Secukinumab high dose
Depending on weight group subject will receive per dose a) 75 mg if weighing less than 25 kg b) 150 mg if weighing between 25 and less than 50 kg c) 300 mg if weighing more than 50 kg. Secukinumab injections (one or two per dose, depending on the weight group) will be administered subcutaneously at Randomization, Weeks 1, 2, 3, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48, and Placebo secukinumab at Weeks 13, 14 and 15 during the blinded phase of the study; thereafter at Week 52 and every 4 weeks during the extension treatment period until Week 232.

At Week 12, subjects in the placebo group based on their PASI 75 response status at Week 12 will proceed as follows: • PASI 75 responders will discontinue study treatment at Week 12 and enter the treatment-free follow-up period • PASI 75 non-responders will receive high dose or low dose secukinumab, according to the pre-assignment at the Randomization visit. They will receive their treatment based on the weight category(<25 kg, 25- <50kg, =50 kg), on Weeks 12, 13, 14, 15, and then every four weeks starting at Week 16 until Week 48 during the maintenance period; thereafter at week 52 and every 4 weeks during the extension treatment period until Week 232.
• Active Comparator: Etanercept
Etanercept 0.8 mg/kg of subject weight and up to a maximum of 50 mg per dose. Subcutaneous etanercept 0.8 mg/kg (one or two injections per dose) once per week, for 51 weeks administered at home (self-injected or by caregiver) or at the study site. At Wk 52 subjects in the etanercept group will move into the treatment-free follow up period and terminate the study.

Secondary	Percentage Change From Baseline in Children's Dermatology Life Quality Index (cDLQI) Score Up to Week 12 (Induction)	The CDLQI measures functional disability of subjects with dermatological disorders who are less than 18 years of age and it has been utilized as a relevant clinical measure in atopic dermatitis, as well as other dermatitis clinical trials. The CDLQI is a simple, validated, self-administered 10-item questionnaire. The instrument contains six functional scales (i.e., symptoms and feeling, leisure, school or holidays, personal relationships, sleep and treatment). The questions are based on the preceding week to permit accurate recall. For the CDLQI, each question will be answered on a 4-point Likert scale scored from 0 to 3. Seven scores will be derived from the CDLQI: the total score of each of the six dimensions as well as the total score over all items. The higher the score, the more quality of life is impaired.

Secondary	Number and Percentage of Participants With Clinically Important Reduction in Disability as Evaluated by CHAQ Questionnaire Over Time at Week 12	The CHAQ questionnaire is only done for children who in addition to psoriasis are also suffering from psoriatic arthritis. The questionnaire is completed by parent or legal guardian. It consists of multiple choice items concerning difficulty in performing eight common activities of daily living; dressing and grooming, arising, eating, walking, reaching, personal hygiene, gripping and other "activities". The person completing the questionnaire chooses from four response categories, ranging from 'without any difficulty' to 'unable to do'. Additionally two visual analog scales (overall well-being and pain of patient) must be performed.	Week 12
