Palmoplantar Pustular Psoriasis Efficacy and Safety With Secukinumab

A 52-week, Multicenter, Randomized, Double-blind, Placebo-controlled Study of Subcutaneous Secukinumab to Demonstrate Efficacy as Assessed by Palmoplantar Pustulosis Psoriasis Area and Severity Index (ppPASI) at 16 Weeks of Treatment, Compared to Placebo, and to Assess Long-term Safety, Tolerability, and Efficacy in Subjects With Moderate to Severe Chronic Palmoplantar Pustular Psoriasis - Amended With an Optional Extension Treatment Period of up to a Total of 148 Weeks

A one year study assessing the efficacy and safety of secukinumab compared with placebo in adult patients with moderate to severe palmoplantar pustular psoriasis - amended with an optional extension treatment period of up to a total of 148 weeks

Inclusion Criteria:

• Palmoplantar pustular psoriasis for at least 6 months before Randomization

• Moderate to severe palmoplantar pustular psoriasis as defined at Baseline by:

  • ppPASI score of ≥ 12 and
  • DLQI ≥ 10

• Candidate for systemic therapy, defined as having palmoplantar pustular psoriasis inadequately controlled by:

  • Topical treatment, and/or
  • Phototherapy, and/or
  • Previous systemic therapy

Exclusion Criteria:

• Forms of psoriasis other than chronic plaque psoriasis and pustular palmoplantar psoriasis (e.g., erythrodermic, guttate, or generalized pustular psoriasis)

• Patients not willing to limit UV light exposure (e.g. sunbathing and/or the use of tanning devices) during the course of the study
• Ongoing use of prohibited psoriasis treatments (e.g., topical or systemic corticosteroids, UV therapy). Washout periods detailed in the protocol have to be adhered to
• Previous exposure to any biologic drug directly targeting IL-17 or IL-17 Receptor (e.g., secukinumab, ixekizumab, or brodalumab)
• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during dosing of study treatment and for 16 weeks after stopping treatment
• Active ongoing inflammatory diseases other than psoriasis that might confound the evaluation of the benefit of secukinumab therapy
