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.

Effective second‑line b/tsDMARDs for patients with rheumatoid arthritis unresponsive to first‑line b/tsDMARDs from the FIRST registry

Rheumatol Ther 2025. Epub ahead of print doi: 10.1007/s40744-025-00747-9

Kanda et al. investigated the efficacy of second-line b/tsDMARDs in RA patients unresponsive to first-line b/tsDMARDs. Using data from the FIRST registry, the study assessed 687 patients with RA treated with TNFis, IL-6 receptor inhibitors, cytotoxic T-lymphocyte-associated protein 4 immunoglobulin, or JAKis. After propensity score-based adjustment, JAKi showed the highest persistence rate, greatest improvement in CDAI, and highest remission rates at 24 weeks. Among JAKi, UPA was most effective in achieving remission, with a safety profile comparable to other b/tsDMARDs.

Effectiveness of JAK Inhibitors Compared with Biologic Disease-Modifying Antirheumatic Drugs on Pain Reduction in Rheumatoid Arthritis: Results from a Nationwide Swedish Cohort Study

Arthritis Rheumatol. 2025;77:253–262 doi: 10.1002/art.43014.

Eberhard et al. investigated the effectiveness of JAKi versus bDMARDs on pain reduction in RA patients, using Swedish national register data. JAKi treatment resulted in a significantly greater reduction in pain at three months compared with TNFis, with a higher proportion achieving low pain at 12 months, particularly in those previously treated with multiple bDMARDs.

Tamuzimod in patients with moderately-to-severely active ulcerative colitis: a multicentre, double-blind, randomised, placebo-controlled, phase 2 induction trial

Lancet Gastroenterol Hepatol. 2025;10:210–221. doi: 10.1016/S2468-1253(24)00386-8.

Sands et al. evaluated tamuzimod, a selective sphingosine 1-phosphate receptor 1 modulator, in patients with moderately-to-severely active UC. At Week 13, clinical remission (defined as an MMS stool frequency subscore of ≤1, rectal bleeding subscore of 0, and endoscopic subscore ≤1, excluding friability) was achieved by 28% and 24% of patients receiving tamuzimod 60 mg and 30 mg, respectively, compared with 11% in the placebo group. The treatment was well tolerated; most AEs were mild or moderate.

Interleukin‑23 versus Interleukin‑17 Inhibitors in Preventing Incidental Psoriatic Arthritis in Patients with Psoriasis: A Real‑World Comparison From the TriNetX US Collaborative Network

BioDrugs. 2025 Mar;39(2):297-306 doi: 10.1007/s40259-025-00705-5

IL23is are associated with a lower risk of PsA incidence compared to IL17is in PsO patients, particularly in specific age, sex, and ethnic groups according to the latest real-world research from Yu S, et al.

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.

Achievement of endoscopic remission after induction reduces hospitalization burden in Crohn’s Disease: findings from a pooled post hoc analysis of risankizumab and upadacitinib Phase III trials

J Crohns Colitis. 2025 Feb 4;19(2):jjae128. doi: 10.1093/ecco-jcc/jjae128.

Panaccione et al. investigated the association between achievement of endoscopic remission following induction therapy and hospitalisation outcomes in Crohn’s disease. Patients achieving endoscopic remission at Week 12 experienced a 55% reduction in Crohn’s disease-related hospitalisation rates over the 52-week maintenance period. The results support endoscopic remission as an early therapeutic target.

Bimekizumab improves patient-reported outcomes and work productivity in patients with psoriatic arthritis: 1-Year results from two Phase 3 studies

J Rheumatol 2025. Epub ahead of print doi: 10.3899/jrheum.2024-0923

Gladman et al. assessed the impact of bimekizumab over 1 year on patient-reported symptoms, HRQoL, and work productivity in patients with PsA who were bDMARD-naïve or TNF-IR. The study showed that bimekizumab treatment resulted in sustained improvements across multiple domains, including pain, fatigue, physical function, and work impairment.

Baricitinib dose reduction in patients with rheumatoid arthritis achieving sustained disease control: Final results from the RA-BEYOND study

J. Rheumatol. 2025 doi: 10.3899/jrheum.2024-0906

Edwards et al. reported that in patients with RA who achieved sustained LDA or remission, tapering baricitinib from 4mg to 2mg allowed most to maintain LDA at 96 weeks. Rescue with 4mg restored control for the majority, demonstrating the feasibility of dose reduction with recovery potential for treatment.
