Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in terms of Psoriasis Area and Severity Index (PASI) 90 in patients with moderate-to-severe plaque psoriasis. Based on PASI 90 response at week 16, patients were stratified as PASI 90 responders (PASI90R, n = 337) or non-responders (PASI90NR, n = 72). At week 20, 94.2% (n = 295/313) achieved PASI 90/100 response in PASI90R, with response maintained through week 48 (89.6%, n = 189/211). An increased proportion of patients achieved PASI 90/100 response in PASI90NR (week 20: 29.9%, n = 20/67; week 48: 57.1%, n = 20/35). Overall, 64.4% patients achieved absolute PASI score=0 at week 24 with response sustained to week 48 (66.9%). Secukinumab showed sustained and stable efficacy in maintaining PASI 90 response in patients with moderate-to-severe plaque psoriasis up to week 48.

Secukinumab, a fully human monoclonal antibody, neutralizes interleukin-17A, a cornerstone cytokine driving the multiple manifestations of psoriatic disease. Secondary loss of response over time has been observed with biologic therapies for psoriasis. This post-hoc analysis of the SUPREME study was performed to determine the sustainability of response to secukinumab in patients with moderate-to-severe plaque psoriasis. After 24 weeks of treatment with secukinumab, the majority of patients achieved complete clearance and response was sustained to week 48, demonstrating the sustainability of response to secukinumab in patients with moderate-to-severe plaque psoriasis.
