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.

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.

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.

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.
