Data from an international collaboration of registries show no evidence of an increase in CV events during the first 2 years of use with JAKi, compared to TNFi, in the general RA population.

October 2025

Bai et al. reported that JAKi therapy was associated with a reduced risk of incident uveitis compared with TNF inhibitors among patients with AS, PsO, or PsA. Authors conducted a large-scale, real world comparative study which evaluated the risk of incident uveitis among patients with psoriatic disease and AS treated with either TNFi or JAKi.

Nozaki et al. showed that JAK inhibitor treatment provided sustained disease control (especially in high-risk RA patients) and promoted GC reduction, although TNF inhibitors remain a standard option. Nozaki et al. evaluated the clinical efficacy and continuation rates of JAK inhibitors and TNF inhibitors in RA patients with poor-prognosis factors (PPFs).

Hernández-Hernández et al. showed that in a real-world clinical settings, UPA persistence is lower among RA patients who have received prior IL-6i treatment; and that treatment strategies to avoid UPA in patients with cardiovascular risk (CVR) appear to be primarily driven by pivotal safety studies rather than regulatory guidance.

Bennett et al, showed that tofacitinib treatment in adults with rheumatoid arthritis led to a significant increase in lower limb and thigh muscle volume, accompanied by rises in serum creatinine without evidence of renal impairment.

August 2025

Baraliakos et al. compared real-world effectiveness of upadacitinib, TNF inhibitors, or IL-17 inhibitors following inadequate response to an initial TNF inhibitor in patients with axSpA. Upadacitinib was associated with greater reductions in pain and fewer affected joints compared with switching to a second TNF inhibitor or IL-17 inhibitor.

Most patients vaccinated with RZV while using UPA 15mg QD and background MTX achieved satisfactory humoral and cell-mediated immune responses to recombinant zoster vaccine (RZV) at Weeks 4, 16 and 60. Winthrop et al. evaluated the immunogenicity of RZV through Week 60 in patients with RA who were receiving UPA 15mg QD and background MTX.

July 2025

UPA has shown effectiveness in treating IMIDs like RA, axSpA, PsA, CD, and UC. Chai et al. evaluated evidence from a synthesis of RCTs and provided insights that may guide clinical decision-making and improve treatment outcomes for IMIDs. UPA effectively alleviated symptoms, reduced disease activity, and showed notable benefits in improving quality of life.

June 2025

Schaefer et al. showed that treatment with JAKis (predominantly BARI and TOF) was associated with an increased HR of malignancies compared to treatment with bDMARDs in the overall study cohort, consistent with results from the ORAL surveillance trial. To better understand the complex role of JAKis in cancer development in RA patients, Schaefer et al. estimated the effects of JAKis compared to bDMARDs on the risk of malignancy (excluding NMSC) in patients with RA.

Wieczorek et al. present the first evidence supporting the use of a dual JAK and ROCK inhibitor as a potential treatment option for patients with RA who have inadequate response to MTX. Wieczorek et al. conducted a randomised, Phase 2 study of CPL’116 in patients with RA with inadequate response to MTX, to evaluate dose-dependent effects on disease control and pharmacokinetics, and its effect on laboratory abnormalities among other safety assessments.
