Long-term clinical efficacy and safety of secukinumab for Japanese patients with psoriasis: A single-center experience

Abstract

Secukinumab is a fully human monoclonal antibody that can selectively neutralize interleukin-17A, and its excellent efficacy has been demonstrated in clinical trials for psoriasis. The aim of our study is to assess long-term efficacy and safety of secukinumab for 52 weeks in real-world clinical practise in our facility. A total of 83 patients (71 with psoriasis vulgaris and 12 with psoriatic arthritis) were included, and 49 of them were bio-switched patients. Psoriasis Area and Severity Index (PASI) 75 and PASI-90 responses were 80% and 64% at week 12, 77% and 65% at week 24, and 76% and 58% at week 52, respectively. No significant differences were observed in efficacy between bio-naive and bio-switched patients. Arthralgia showed improvement by week 12 in all patients with psoriatic arthritis with a reduction of serum C-reactive protein level. Treatment was discontinued in 22% (18/83), including eight patients with no improvement or exacerbation of cutaneous manifestations, one patient with new onset of arthritis and two patients with transient infection. Overall, secukinumab showed a sustained clinical response with an acceptable safety profile through week 52 in Japanese psoriatic patients.
