Cost-per-Responder Analysis of Bimekizumab (IL-17A/F Inhibitor) Against IL-Inhibitors for Psoriatic Arthritis in Spain, Based on Matching-Adjusted Indirect Comparisons

CPR analyses based on MAIC response rates at week 52 suggest that bimekizumab is more cost-efficient than IL-12/23 and IL-23 therapies, including ustekinumab, guselkumab and risankizumab, for treating PsA in Spain across both bDMARD-naïve patients and patients with TNFi-IR for all outcomes (MDA, ACR50/70). Compared to IL-17A (secukinumab), bimekizumab is consistently cost-efficient in patients with TNFi-IR for all outcomes and is cost-efficient in bDMARD-naïve patients versus those taking 300 mg regarding MDA and ACR70.
