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.

April 2024

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.

March 2024

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.

April 2023

Post hoc analysis of guselkumab, Phase 3 DISCOVER-1 and -2 studies finds that 75% of guselkumab-randomised patients have complete resolution of dactylitis through one year.

TNF inhibitors (TNFi) are one main mode of therapy in patients with PsA who fail to respond to csDMARDs. However, they have a primary treatment failure rate of 40% and only a modest target of ≥20% ACR20 response. The objective of this study was to evaluate efficacy and safety of guselkumab, interleukin-23 inhibitor in the DISCOVER-1 study with active PsA patients by prior use of TNFi.

March 2023

Data from this paper provides a robust analysis of radiographic progression through 2 years in a phase 3 study of guselkumab in patients with PsA. This study sought to evaluate the relationship between radiographic progression and clinical outcomes in post hoc analyses of patients with PsA receiving up to 2 years of guselkumab therapy in DISCOVER-2.

February 2023

Guselkumab was approved for treating the signs and symptoms of active PsA following two Phase 3 global studies, DISCOVER-1 and DISCOVER-2. The Phase 3b APEX study has been designed to address the limitations of DISCOVER-2 and further assess the effects of guselkumab Q4W and Q8W on PsA outcomes.

September 2022

In the latest study by Curtis, et al. guselkumab treatment regimens improved general HRQoL as measured by the EQ-5D-5L Index and EQ-VAS. In reaching this conclusion investigators aimed to determine the minimal important difference for both instruments and to understand the associations between patient-reported EQ-5D-5L Index and EQ-VAS scores as well as key PsA clinical features.
