Mease et al. showed that guselkumab provided significantly higher rates of clinical improvement and significant inhibition of structural damage progression versus PBO, with no new safety signals, at Week 24 in biologic-naïve participants with active and erosive PsA. Mease et al. report primary efficacy and safety results for the double-blind PBO-controlled phase (Weeks 0-24) of the 3-year APEX study.

Impact of dactylitis and enthesitis resolution on disease control in guselkumab-treated psoriatic arthritis patients with TNFi-IR: COSMOS post hoc analysis

Rheumatology 2025;00:1–10 Doi: 10.1093/rheumatology/keaf490

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).

Results from the Phase 3 GRAVTI study by Hart et al. showed that SC induction followed by SC maintenance treatment with guselkumab resulted in superior clinical and endoscopic improvements in participants with moderately to severely active CD through 48 weeks compared with placebo. Hart et al. evaluated efficacy and safety of guselkumab SC induction followed by SC maintenance in participants with moderately to severely active CD in a treat-through design.

A long-term real-world safety study of guselkumab in patients with psoriasis who have infectious comorbidities, malignancies or heart disease: the EARLY study

This study by Mortato et al. enhanced the limited safety data on guselkumab in patients with moderate-to-severe plaque psoriasis who have clinically relevant infectious and oncological comorbidities as well as concomitant heart disease. Authors assessed clinical outcomes and safety of guselkumab in a large cohort of patients with concomitant chronic infection, cancer or heart disease over a long follow-up period, addressing critical gaps in clinical evidence.

Guselkumab for the treatment of moderate-to-severe plaque psoriasis in paediatric patients: results of the phase III randomised placebo-controlled PROTOSTAR study

Prajapati et al. conducted the PROTOSTAR trial to assess guselkumab in paediatric patients with moderate-to-severe plaque psoriasis. Guselkumab significantly improved skin clearance versus placebo at Wk16, with high response rates sustained through Wk52 and a favourable safety profile.
