Significant improvements in overall disease activity, enthesitis and dactylitis, and skin psoriasis were observed by Week 8 and maintained or improved through Week 100 in both guselkumab treatment groups. Coates et al conducted a post-hoc analysis of the Phase 3 DISCOVER-2 trial to investigate the long-term (100-week) efficacy of guselkumab across GRAPPA-identified PsA domains.

Increasing proportions of guselkumab-randomized patients met MDA domain criteria through
Week 100.

February 2024

Guselkumab treatment exhibited generally comparable and significant pharmacodynamic effects on IL-23/Th17–associated cytokines across participants with PsA who are biologic-naïve or have TNFi-IR. In coming to this conclusion, investigators assessed and compared immunologic differences and associations with clinical response to guselkumab in participants with active PsA who were biologic-naïve or TNFi-IR.

November 2023

Data gathered from 11 phase 2 and phase 3 trials have shown that guselkumab has a favourable safety profile in treating psoriatic disease. The data were gathered from 4399 patients over 10787 patient years. In the placebo-controlled periods, guselkumab showed a similar safety profile to placebo, and this remained consistent and stable in the non-placebo controlled preiods.
