Real world practice indirect comparison between guselkumab and risankizumab: Results from an Italian retrospective study.

Abstract

IL‐23‐inhibitors, such as guselkumab and risankizumab, represent the newest class of biologics approved for psoriasis. Phase III trials have shown their efficacy and safety. However, real life data are still scant. to indirectly compare the effectiveness, safety and tolerability of guselkumab and risankizumab in real world practice. An Italian single‐center retrospective cohort study enrolling moderate‐to‐severe psoriasis patients from September 1, 2018 and December 31, 2020 was performed to indirectly compare guselkumab and risankizumab efficacy and safety. Sixty eight patients were included (36 received guselkumab and 32 risankizumab). The groups were comparable for all analyzed characteristics, except for mean psoriasis duration (p < 0.01) which was higher for guselkumab. In guselkumab group, mean PASI reduced from 16.1 ± 6.4 (baseline) 2.1 ± 0.9 (week‐28) (p < 0.001) up to 0.9 ± 0.8 (week‐44) (p < 0.001). In risankizumab group mean PASI decreased from 13.5 ± 4.9 (baseline) 1.9 ± 0.8 (p < 0.001), (week‐28) (p < 0.001) up to 0.9 ± 0.4 (week‐40) (p < 0.001). No significant difference in mean PASI and BSA were observed between the treatments. No cases of serious AEs, injection site reaction, candida, malignancy, cardiovascular events were reported in both groups. Guselkumab and risankizumab showed favorable efficacy and safety profile, being comparable in terms of PASI90 and PASI100 responses as well as in AEs frequency and discontinuation rates.
