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.

Long-term safety and sustained efficacy of bimekizumab in patients with ankylosing spondylitis (radiographic axial spondyloarthritis): 5-year results from BE AGILE (phase 2b) and its open-label extension

MD Open. 2025;11:e005081 doi: 10.1136/rmdopen-2024-005081

Deodhar et al. assessed the long-term safety, tolerability and efficacy of bimekizumab in patients with r-axSpA over five years. The study found that bimekizumab maintained disease control achieved at Wk48 through Wk256, with no new safety signals observed. Adverse events were consistent with previous reports, and clinical benefits, including improvements in disease activity and patient-reported outcomes, were sustained.

Long-Term Safety and Efficacy of Bimekizumab in Axial Spondyloarthritis: 2-Year Results from Two Phase 3 Studies

Rheumatol. 2025. Epub ahead of print. doi: 10.1093/rheumatology/keaf009

Baraliakos et al. evaluated the long-term safety and efficacy of bimekizumab in axSpA through a 2-year analysis of the BE MOBILE 1 and BE MOBILE 2 studies. Bimekizumab was well tolerated, with a consistent safety profile and no new safety signals. Clinical improvements, including ASAS40 response and MRI remission, were sustained through Wk104.

Switching to biological DMARDs versus cycling among JAK inhibitors in patients with rheumatoid arthritis and with inadequate response to JAK inhibitors: from FIRST registry

RMD Open. 2025 Jan 21;11:e004987

Miyazaki et al. investigated the efficacy and safety of switching to bDMARDs versus cycling among JAKis in RA patients with inadequate JAKi response. Cycling to another JAKi proved more effective in improving disease activity at 26 weeks compared to switching to a bDMARD, and both groups had similar safety profiles.

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.

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.

Efficacy and safety of mirikizumab in patients with moderately-to-severely active Crohn’s disease: a phase 3, multicentre, randomised, double-blind, placebo-controlled and active-controlled, treat through study

Lancet 2024;404:2423–36 doi: 10.1016/S0140-6736(24)01762-8

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.

Development of extra-musculoskeletal manifestations in upadacitinib-treated patients with psoriatic arthritis or axial spondyloarthritis

Arthritis & Rheumatology 2024. Epub ahead of print doi: 10.1002/art.43069

Poddubnyy et al. analysed five clinical trials to evaluate extra-musculoskeletal manifestations (EMMs) like uveitis, IBD, and psoriasis in patients treated with UPA. They observed low incidences across PsA, r-axSpA, and nr-axSpA. Numerically, uveitis rates were lower in
UPA-treated patients than in those receiving placebo, particularly in r-axSpA.

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.

Indirect comparison of deucravacitinib and other systemic treatments for moderate to severe plaque psoriasis in Asian populations: A systematic literature review and network meta-analysis

J Dermatol. 2024;51:1559–1571 doi: 10.1111/1346-8138.17448

Tsai et al. conducted a systematic literature review and network meta-analysis evaluating deucravacitinib and other systemic treatments for moderate-to-severe plaque psoriasis in Asian populations. The authors reported that deucravacitinib achieved PASI75 and PASI90 response rates of 66% and 40%, respectively, higher than placebo and apremilast.
