Marzo-Ortega et al. report that dactylitis and enthesitis are associated with a greater disease burden and worse prognosis, highlighting the importance for physicians to identify these conditions and provide adequate treatment. Authors evaluated guselkumab’s efficacy on dactylitis resolution (DR) and enthesitis resolution (ER), and their impact on subsequent disease control, in patients with active PsA and prior inadequate response to tumour necrosis factor inhibitors (TNFi-IR).

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.

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.
