Ferrante et al. conducted a phase 3 trial evaluating the efficacy and safety of mirikizumab in patients with moderately-to-severely active Crohn’s disease. The study demonstrated that mirikizumab significantly improved clinical and endoscopic outcomes compared with placebo at week 52, with a favourable safety profile and tolerable adverse events.

McInnes et al. assessed the efficacy of guselkumab over 48 weeks in patients with psoriatic arthritis who had an inadequate response to TNF inhibitors. The results demonstrated consistent improvements in joint, skin, and patient-reported outcomes across all baseline-defined subgroups. Guselkumab showed greater efficacy compared with placebo at Week 24, with responses maintained or improved through Week 48.

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.

Thaçi, et al. show that guselkumab (GUS) had higher efficacy and a more tolerable safety profile compared with fumaric acid esters (FAE) in patients with moderate. Long-term efficacy through 100 weeks of treatment was seen with GUS as a first-line systemic treatment, and as a second-line systemic treatment in FAE nonresponders.

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.

Guselkumab induced greater clinical and endoscopic improvements in patients with Crohn’s disease versus placebo, with a favourable safety profile in this Phase 2 trial by Sandborn, et al.

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.

Patients treated with guselkumab showed an improved and sustained clinical response compared to both adalimumab and placebo, without compromising safety profile. The Phase 3 VOYAGE 2 trial by Reich et al focused on treatment interruption and withdrawal, as well as treatment switching from adalimumab to guselkumab.

Guselkumab demonstrated superiority to adalimumab and placebo in treating PsO in this Phase 3 study. Improvements in IGA and PASI scores were observed as early as Week 16 and were maintained up to Week 48. Incidence of adverse events was similar across both treatment groups.

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