    Abstract:
    BACKGROUND: Palmoplantar pustular psoriasis (PPP) is a debilitating disease of the palms and/or soles that is resistant to treatment. Secukinumab, an anti-interleukin 17A monoclonal antibody, is highly efficacious in the treatment of moderate-to-severe psoriasis. OBJECTIVE: The primary objective was to determine the rate of achievement of a 75% improvement from baseline in Palmoplantar Psoriasis Area and Severity Index (PPPASI75) with secukinumab at week 16 versus with placebo (at a 2.5% significance level). METHODS: 2PRECISE was a phase 3b multicenter, randomized, double-blind, placebo-controlled, parallel-group study comparing treatment with 300 mg of secukinumab (n = 79), 150 mg of secukinumab (n = 80), and placebo (n = 78) in subjects with moderate-to-severe PPP over a period of 52 weeks. RESULTS: The primary end point was not met. At week 16, 26.6% of subjects treated with 300 mg of secukinumab achieved PPPASI75 versus 14.1% of those who received placebo (P = .0411) (odds ratio, 2.62; 95% confidence interval, 1.04-6.60). At week 52, 41.8% of subjects treated with 300 mg of secukinumab had achieved ppPASI75. More Dermatology Life Quality Index responses of 0 or 1 were achieved with 300 mg of secukinumab (13.0%) than with placebo (4.3%) at week 16. At week 52, 43.1% of subjects receiving 300 mg of secukinumab had a Dermatology Life Quality Index response of 0 or 1. No unexpected adverse events were observed. LIMITATIONS: Small sample size and characteristics of the PPP disease course. CONCLUSION: Patients with PPP who were treated with secukinumab, 300 mg, showed benefit in terms of PPPASI75 responses over 52 weeks and improved quality of life.
