Efficacy and safety of secukinumab in Taiwanese patients with moderate to severe plaque psoriasis: Subanalysis from ERASURE phase III study.

The efficacy and safety of secukinumab, a fully human anti-interleukin-17A monoclonal antibody, has been evaluated for moderate to severe plaque psoriasis in global trials which have included a low proportion of Asian subjects. We analyzed the efficacy and safety of secukinumab in Taiwanese patients in a phase III global clinical trial (ERASURE). Fifty-one Taiwanese patients were randomized into s.c. placebo, 150 and 300 mg secukinumab treatment groups. The proportions of patients who achieved 75% or more improvement in Psoriasis Area and Severity Index (PASI-75) at week 12 were 87.5% with 300 mg secukinumab, 70% with 150 mg secukinumab, 0% with placebo. Of the patients receiving 300 mg secukinumab, 68.8% achieved PASI-90 at week 12. Analysis of overall patients receiving 300 mg secukinumab for 12 weeks showed that the proportion of PASI-75 responders was less in patients with body mass index of 25 or more than less than 25. During the entire 52 weeks, the incidence of adverse events (AE) was consistent with the overall population in ERASURE. The most common AE (cases/per 100 patient-year) during the entire treatment period were upper respiratory tract infection and pruritus. The duration of upper respiratory tract infection per 100 patient-year was approximately 399 days in placebo, 1261 days in 150 mg secukinumab and 1805 days in 300 mg secukinumab. The safety and efficacy of secukinumab in Taiwanese patients was compatible with the global phase III study in the treatment of moderate to severe plaque psoriasis.
