Obefazimod in patients with moderate-to-severely active ulcerative colitis: efficacy and safety analysis from the 96-week open-label maintenance phase 2b study

Journal of Crohn's and Colitis 2025;19:jjaf074 doi: 10.1093/ecco-jcc/jjaf074

Vermeire et al. provides data that supports the long-term efficacy and safety of obefazimod 50mg QD, with a substantial proportion of patients achieving clinical remission at Weeks 48 and 96. Vermeire et al. evaluated the 2-year outcome data of an OLM study, which assessed the long-term safety and efficacy of obefazimod 50mg QD.

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

Arthritis Rheumatol 2025;77:536–46 doi: 10.1111/1756-185X.70212

Poddubnyy et al. identified no apparent increase in the risk of developing extramusculoskeletal manifestations (EMMs) in patients with PsA, r-axSpA, and nr-axSpA receiving 15mg UPA in the SELECT trials. Majority of patients did not report a history of EMMs at baseline, regardless of disease indication or study treatment.

Long-term effectiveness and safety of deucravacitinib for psoriasis: a 52-week real-world study of genital, scalp and nail lesions

Clin Exp Dermatol. 2025 Apr 24;50(5):952-959 doi: 10.1093/ced/llae530. PMID: 39657275.

Real-world effectiveness and safety data suggest that deucravacitinib is a valuable long-term treatment option for PsO.

Efficacy and safety of zimlovisertib, ritlecitinib and tofacitinib, alone and in combination, in patients with moderate to severe rheumatoid arthritis and an inadequate response to methotrexate

Arthritis Rheumatol. 2025 doi: 10.1002/art.43184 Epub ahead of print

Phase 2 study data show that zimlovisertib + tofacitinib was more effective than tofacitinib alone, in patients with moderate-to-severe RA and an inadequate response to MTX.

The concept of difficult-to-treat disease in rheumatology: where next?

Lancet Rheumatol. 2025;7:e274–89 doi: 10.1016/S2665-9913(24)00340-0

Nagy et al. propose a unifying and holistic framework for understanding and addressing the concept of difficult-to-treat (D2T) disease across rheumatology, integrating cross-disciplinary evidence and recommending its incorporation into future disease management strategies. The D2T state requires a comprehensive, holistic, multidisciplinary approach that considers the specific characteristics of each disease and the personalised needs of the patient.

Burden and determinants of multi-b/tsDMARD failure in psoriatic arthritis

Arthritis Research & Therapy 2025;27:46 doi: 10.1186/s13075-025-03518-7

Haberman et al. analysed prescribing patterns and characteristics of PsA patients with
multi-b/tsDMARD failure, defined as requiring ≥4 b/tsDMARDs. Among 960 patients at the NYU Psoriatic Arthritis Centre, 17% met this criterion. These patients were more likely to be female, obese, and have higher rates of axial involvement and depression. They also exhibited greater disease activity, suggesting that both inflammatory and non-inflammatory factors contribute to multiple treatment failures.

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.

Upadacitinib in active non-radiographic axial spondyloarthritis: 2-year data from the phase 3 SELECT-AXIS 2 study

Arthritis Res Ther. 2025;27:23. doi: 10.1186/s13075-024-03441-3

Van den Bosch et al. reported that upadacitinib 15 mg once daily led to sustained improvement in nr-axSpA over two years, including disease activity, pain, and quality of life. The study reports that 57.1% achieved ASAS40 response at week 104, with no new safety signals identified.
