Study of Safety, Tolerability, and Efficacy of Secukinumab in Subjects With Moderate to Severe Palmoplantar Psoriasis

A Randomized, Double-blind, Placebo-controlled, Multicenter Study to Demonstrate the Efficacy at 16 Weeks of Secukinumab 150 and 300 mg s.c. and to Assess Safety, Tolerability and Long-term Efficacy up to 132 Weeks in Subjects With Moderate to Severe Palmoplantar Psoriasis

Purpose of the study was to demonstrate the efficacy of secukinumab versus placebo on palmoplantar psoriasis and to assess the long term efficacy, safety and tolerability of secukinumab.

Inclusion Criteria:

• Subjects with chronic, moderate to severe plaque type psoriasis for at least 6 months prior to randomization and significant involvement of the palms and soles at baseline, defined as palmoplantar Investigator's Global Assessment (ppIGA) score of ≥ 3 on a 5-point scale, as well as at least one skin plaque at baseline which is not in the palmoplantar area
• Candidates for systemic therapy, i.e. psoriasis inadequately controlled by topical treatment (including super potent topical corticosteroids) and/or phototherapy and/or previous systemic therapy

Exclusion Criteria:

• Forms of psoriasis other than chronic plaque type psoriasis (e.g., pustular psoriasis, palmoplantar pustulosis, acrodermatitis of Hallopeau, erythrodermic and guttate psoriasis)
• Drug-induced psoriasis (e.g. new onset or current exacerbation from β-blockers, calcium channel inhibitors or lithium)
• Ongoing use of prohibited treatments (e.g. topical or systemic corticosteroids (CS), UV therapy). Washout periods do apply.
• Prior exposure to secukinumab (AIN457) or any other biological drug directly targeting IL-17 or the IL-17 receptor
• Use of any investigational drugs within 4 weeks prior to study treatment initiation 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 therapy
• History of hypersensitivity to constituents of the study treatment
