Mease et al. conducted a post-hoc analysis of the phase 3 DISCOVER-2 trial to assess the persistence of clinically relevant improvements with guselkumab in biologic-naïve patients with PsA. The analysis showed that guselkumab maintained clinical improvements in joint and skin domains at consecutive dosing visits (Q8W) and over time.

Ritchlin et al. conducted a post hoc analysis of the DISCOVER-2 trial, evaluating the efficacy of guselkumab in biologic-naïve patients with PsA. Guselkumab provided durable disease control across key PsA domains and PROs over 2 years, regardless of baseline characteristics. A significant proportion of patients achieved stringent endpoints such as ACR50/70, complete skin clearance, and resolution of dactylitis/enthesitis.

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

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.
