When IL‐17 inhibitors fail: real‐life evidence to switch from secukinumab to adalimumab or ustekinumab

Psoriasis is a chronic, systemic inflammatory disease that in the moderate to severe forms may benefit of biologics, namely TNF and IL‐12/23 and IL‐17 inhibitors. Loss of response, lack of response or discontinuation due to adverse events represent a concrete therapeutic challenge for dermatologists that have to switch patients to other treatments. Although some evidences already exist toward the switch from IL‐12/23 and TNF inhibitors to IL‐17 inhibitors, conversely nothing is present toward the switch from IL‐17 inhibitors to IL‐12/23 and TNF inhibitors. We performed a real‐life study enrolling 50 patients randomly switched to adalimuamb, a TNF inhibitor, or ustekinumab, an IL‐12/23 inhibitor. Our observational study suggests that switching from IL‐17i to TNFi and IL‐12/23i is a safe and effective therapeutic strategy.
