The SELECT-MONOTHERAPY study evaluated the safety and efficacy of UPA monotherapy through 260 weeks of treatment, in patients with RA who had prior inadequate response to MTX. No new safety signals were observed with long-term exposure to UPA, and results were consistent with prior findings and the established safety profile of UPA across indications. These data support the potential of UPA as a treatment option for patients with moderate to severe active RA who have responded inadequately to MTX.

Mariette et al. investigated the long-term safety of filgotinib with regard to MACE, VTE and malignancy across RA and UC clinical trial populations. Rates of these events remained low overall, with some increases observed in patients aged 65 years and older.

March 2025

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.

January 2025

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.

October 2024

Buch et al. demonstrated that filgotinib sustained its efficacy in rheumatoid arthritis patients through Wk156 in the FINCH 4 long-term extension study, showing stable safety profiles. The study reported high ACR response rates and remission based on Boolean criteria, underlining filgotinib's potential for extended clinical benefits.

September 2024

Tanaka et al. observed that in Japanese patients with rheumatoid arthritis treated with tofacitinib, those with absolute lymphocyte counts (ALCs) <0.5x10³ cells/mm³ had a higher risk of serious infections and herpes zoster events compared to patients with higher ALC levels. This threshold may help identify increased infection risk in this population

July 2024

McInnes et al. reported that bimekizumab demonstrated sustained efficacy and safety over 52 weeks in patients with psoriatic arthritis (PsA), regardless of concomitant methotrexate (MTX) use. Both bimekizumab groups (with and without MTX) showed similar improvements in achieving ACR50 and PASI100 responses.

May 2024

More RA patients on upadacitinib versus adalimumab achieved clinical remission, LDA, and DAS28 (CRP) <2.6. Radiographic progression was less with continuous upadacitinib versus continuous adalimumab. Upadacitinib showed similar safety to adalimumab, with higher incidences of HZ, lymphopenia, CPK elevation, hepatic disorder and nonmelanoma skin cancer.

April 2024

The 2023 EULAR recommendations provided an updated consensus on the pharmacological management of PsA with a new overarching principle and recommendation for 2023. Recent MOA safety data emphasised the importance of patient-specific benefit-risk profiling in JAKi therapy, and extra-musculoskeletal (MSK) manifestations related to PsA should be considered during drug selection.

Burmester, et al. found that long-term filgotinib exposure was well tolerated in patients with moderate-to-severe active RA, with a stable rate of TEAEs over time. However, potential dose-dependent relationships for herpes zoster infections, malignancies and all-cause mortality were observed in patients aged ≥65 years, indicating the potential impact of age on the safety profile of Filgotinib. Therefore, some patients aged ≥65 years may benefit from the filgotinib 100 mg dose option.
