The success rate of switching between IL-17 inhibitors is high and is independent of the patient's body weight and the presence of psoriatic arthritis. The switch from secukinumab to brodalumab has the best outcome.
The IL-17 cytokine family encompasses six different homodimers and heterodimers referred to as IL-17A-F. Due to some differences in the mechanism of IL-17 inhibition, aninsufficient effect of one IL-17 inhibitor does not necessarily imply lack of efficacy of the other agent of the same class. Aim of study was analysis of the success rate of switches among IL-17 inhibitors (secukinumab, ixekizumab, and brodalumab) in patients treated in the Czech Republic. Data were obtained from the Czech nationwide registry of psoriatic patients receiving biological/targeted therapy (BIOREP). Our analysis involved data of a total of 90 patients with severe chronic plaque psoriasis and baseline PASI scores >10 both prior to first-line biological therapy initiation and after switch to another agent of the class of IL-17 inhibitors. The most effective switch was that from secukinumab to brodalumab, with PASI 90 reached by 64.7% and 73.3% of patients at weeks 12 and 24. Among patients switched from secukinumab to ixekizumab target PASI 90 responses were achieved (at weeks 12 and 24) by 41.2% and 55.2% of patients. Among patients switched from ixekizumab to brodalumab target PASI 90 responses were achieved, at the above time points, by 30.8% and 38.5% of patients. Our analysis showed a high success rate of switches from secukinumab to ixekizumab and brodalumab, followed by the ixekizumab-to-brodalumab switch. Importantly, the therapeutic response and success rates of individual switches are independent of the patient's body weight and presence of psoriatis arthritis.
