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

Br J Dermatol 2025;192:618–628 doi: 10.1093/bjd/ljae502

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.

Treatment of psoriasis with different classes of biologics reduces the likelihood of peripheral and axial psoriatic arthritis development

Rheumatology (Oxford). 2025;64:1131–1137. doi: 10.1093/rheumatology/keae257

Floris et al. conducted a monocentric cohort study to assess the impact of biologic treatment on the development of PsA in patients with PsO. Treatment with biologics significantly reduced the likelihood of PsA development, with lower prevalence observed across different biologic classes and patterns of joint involvement.

Safety and efficacy of deucravacitinib in moderate to severe plaque psoriasis for up to 3 years: An open-label extension of randomized clinical trials

JAMA Dermatology 2025;161:56–66 doi: 10.1001/jamadermatol.2024.4688

Armstrong et al. evaluated the long-term safety and efficacy of deucravacitinib in patients with moderate to severe plaque psoriasis over a three-year period. The study found that exposure-adjusted incidence rates of AEs remained stable or declined over time, with no new safety signals emerging. Clinical response rates, including PASI75/90, were maintained, supporting the drug’s long-term efficacy.

Sustained response to guselkumab regardless of baseline characteristics in patients with active psoriatic arthritis and inadequate response to TNF inhibitors: results from the phase 3b COSMOS clinical trial

RMD Open. 2024 Dec 12;10(4):e004494. doi: 10.1136/rmdopen-2024-004494.

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.

Interleukin-23 vs. interleukin-12/23 inhibitors on preventing incidental psoriatic arthritis in patients with psoriasis? A real-world comparison from the TriNetX Global Collaborative Network

J Am Acad Dermatol 2024 Nov;91:889–895 doi: 10.1016/j.jaad.2024.07.1473

Tsai et al. observed no significant difference in the incidence of psoriatic arthritis among psoriasis patients treated with IL-23 inhibitors compared to IL-12/23 inhibitors, although there was a numerically lower PsA risk with IL-23 inhibitors. Results indicate both therapies are similarly effective for PsO management.

Comparative early effectiveness across 14 PsA drugs and 5 classes of PsA treatment: 3-month results from the PRO-SPIRIT study

MD Open. 2024 Sep 20;10:e004318 doi: 10.1136/rmdopen-2024-004318

Kristensen et al. compared 14 PsA drugs across five treatment classes, evaluating their real-world effectiveness over three months. Ixekizumab showed rapid effectiveness on joint disease activity and skin outcomes, performing better than IL-12/23i and IL-23i, and comparable to TNFi and JAKi. More patients with active psoriasis achieved minimal disease activity with Ixekizumab than other therapies.

Mental health outcomes in patients with moderate to severe psoriasis treated with bimekizumab: Analysis of Phase 2/3 randomized trials

J Am Acad Dermatol 2024;91:72–81 doi: 10.1016/j.jaad.2024.02.039

Results of this analysis by Blauvelt, et al. showed a low adjudicated suicidal ideation and behaviour (SIB) rate of 0.13/100 patient-years for bimekizumab, consistent with general psoriasis population ranges. Bimekizumab did not increase the risk of SIB compared to other anti-IL-17A/anti-IL-23 therapies.

Durable Control of Psoriatic Arthritis with Guselkumab Across Domains and Patient Characteristics: Post Hoc Analysis of a Phase 3 study

Clin Rheumatol 2024 doi: 10.1007/s10067-024-06991-8 Epub ahead of print

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.

Enthesitis and dactylitis resolution with risankizumab for active psoriatic arthritis: Integrated analysis of the randomized KEEPsAKE 1 and 2 Trials

Dermatol Ther 2024;14:1517–1530 doi: 10.1007/s13555-024-01174-4

Kwatra et al. found that risankizumab significantly improves clinical signs and symptoms of enthesitis and/or dactylitis in PsA patients, with substantial and sustained efficacy observed up to 52 weeks. Furthermore, these improvements were met by meaningful gains in patient reported outcomes.

Phase 2 trial of deucravacitinib in psoriatic arthritis: Biomarkers associated with disease activity, pharmacodynamics, and clinical responses

FitzGerald, et al. found that Deucravacitinib significantly impacted biomarkers associated with TYK2 signalling pathways of key inflammatory cytokines, including IL-23 and Type I IFN, and those related to collagen matrix turnover.
