Secukinumab Shows Significant Efficacy in Palmoplantar Psoriasis: Results from GESTURE, a Randomized Controlled Trial
BACKGROUND: Plaque psoriasis affecting palms and soles is disabling and often resistant to treatment. OBJECTIVE: Evaluate the efficacy and safety of secukinumab, an anti-interleukin 17A antibody, in subjects with palmoplantar psoriasis. METHODS: In this double-blinded, randomized controlled trial, 205 subjects were randomized 1:1:1 to secukinumab 300 mg, 150 mg, or placebo. The primary endpoint was Palmoplantar Investigators Global Assessment (ppIGA) 0 (clear) or 1 (almost clear/minimal) response at week 16. RESULTS: At week 16, the percentage of subjects who achieved clear or almost clear palms and soles (or ppIGA 0/1) with secukinumab 300 mg (33.3%) and 150 mg (22.1%) was superior to the percentage achieved with placebo (1.5%, P<.001). Palmoplantar Psoriasis Area and Severity Index (ppPASI) was significantly reduced with secukinumab 300 mg (-54.5%) and 150 mg (-35.3%) compared with placebo (-4.0%, P<.001). Dermatology Life Quality Index (DLQI) 0/1 responses from subjects in the secukinumab groups were also significantly higher compared with placebo at week 16 (P<.01) and pain and function of palms and soles was markedly improved with secukinumab as measured by the palmoplantar Quality-of-Life Instrument. Secukinumab 300 mg consistently showed the best outcomes. The safety profile was favorable and similar to previous studies. LIMITATIONS: Lack of active comparator. CONCLUSION: In GESTURE, the largest randomized controlled trial in palmoplantar psoriasis, secukinumab demonstrated the greatest efficacy to date for treating difficult-to-treat psoriasis.
