Brief summary
This study will assess the efficacy and safety of secukinumab compared to placebo in adult patients who have moderate to severe scalp psoriasis that is poorly controlled by current psoriasis treatments.
Interventions
Secukinumab 300 mg will be provided in 1 mL prefilled syringes of 150 mg. Each dose of 300 mg secukinumab will consist of two secukinumab 150 mg injections once weekly for 5 weeks (Baseline, Weeks 1, 2, 3 and 4), followed by dosing every four weeks starting at Week 8 through Week 20 inclusive. In order to maintain the blinding, patients will receive additional placebo injections at Weeks 13, 14 and 15. The patients (or caregivers) will self-inject each dose at the study site under the supervision of site personnel when injections occur of days of study visits. The injections not occurring during a study visit will be done by the patients (or caregivers) at home.
Placebo will be provided in 1 mL prefilled syringe. Each placebo dose will consist of two placebo injections once weekly for five weeks (Baseline, Weeks 1, 2, 3 and 4), then after four weeks at Week 8. At Week 12, PSSI responders will continue on placebo and receive their injections once weekly for five weeks (Weeks 12, 13, 14, 15 and 16), then followed by dosing after four weeks at Week 20. PSSI non-responders will be switched to receive 300 mg secukinumab at Weeks 12, 13, 14, 15 and 16, then after four weeks at Week 20. The patients (or caregivers) will self-inject each dose at the study site under the supervision of site personnel when injections occur on days of study visits. The injections not occurring during a study visit will be done by the patients (or caregivers) at home.

Eligibility
Inclusion criteria
* Chronic scalp psoriasis for at least the previous six months * Moderate to severe scalp psoriasis as defined by a PSSI score of ≥12 and 30% or higher of scalp surface area affected * Must be candidates for systemic therapy, which means having scalp psoriasis inadequately controlled by topical treatments (corticosteroids), and/or phototherapy, and/or previous systemic therapy.
Exclusion criteria
* Forms of psoriasis other than chronic plaque * Drug-induced psoriasis (e.g., new onset or current exacerbation from β-blockers, calcium channel inhibitors) * Ongoing use of prohibited treatments (e.g., topical or systemic corticosteroids, UV therapy) * Prior exposure to secukinumab (AIN457) or any other biologic drug directly targeting IL17A or IL-17RA receptors * Use of other investigational drugs within 30 days prior to study entry, or within a period of 5 half-lives of the investigational treatment, whichever is longer * Active, ongoing inflammatory diseases other than psoriasis that might confound the evaluation of the benefit of secukinumab * Active system infections (with the exception of the common cold) during the two weeks prior to starting study treatment * Other protocol-defined inclusion/

| Secukinumab Eligible patients received secukinumab 300 mg once weekly at Baseline, Weeks 1, 2, 3 and 4 followed by monthly dosing starting at Week 8 through Week 20 inclusive | 51 |
| Placebo Eligible participants received placebo doses once weekly at Baseline, Weeks 1, 2, 3 and 4 followed by a dose after four weeks at Week 8. Prior to taking the Week 12 dose, participants were assessed for response to treatment using the Psoriasis Scalp Severity Index (PSSI).
