Su et al. conducted a comprehensive systematic review and network meta-analysis to assess the efficacy and safety of therapies for difficult-to-treat (D2T) RA. They found that tocilizumab and rituximab had superior efficacy and safety profiles, with 8mg every 4 weeks of tocilizumab identified as the optimal therapeutic dose.

Kandeel et al. compared JAK inhibitors and TNF inhibitors in RA. JAK inhibitors demonstrated better functional improvement via HAQ-DI but showed insignificant difference in CDAI compared to TNF inhibitors; both classes had similar safety.

van Vollenhoven et al. compared the efficacy and safety of upadacitinib monotherapy to methotrexate monotherapy over five years in methotrexate-naïve patients with rheumatoid arthritis. The study found that upadacitinib provided better long-term efficacy and higher rates of disease activity remission than methotrexate; however, it was associated with higher incidences of adverse events, particularly at the higher dose of 30 mg.

Fleischmann et al. evaluated the long-term efficacy and safety of upadacitinib in rheumatoid arthritis patients with inadequate response or intolerance to bDMARDs over five years. The study demonstrated that upadacitinib 15 mg and 30 mg were effective in maintaining disease control, with >75% of patients achieving CDAI LDA by week 260. The safety profile remained consistent with no new issues identified.

Adami et al. conducted a retrospective analysis to evaluate the GC sparing effects of JAKi versus bDMARDs in rheumatoid arthritis patients. They found that JAKi therapy was associated with a significant reduction in GC dose compared with bDMARDs. This suggests that JAKi could be more effective in reducing long-term GC exposure in RA patients.

Patients classified as having a high neutrophil-to-lymphocyte ratio (NLR-High) who received filgotinib 200mg + MTX/csDMARDs exhibited consistently better responses after 12 weeks across clinical trials, clinical endpoints, and PROs, compared with NLR-Low patients. Taylor et al. analysed data from the 3 FINCH trials to investigate the potential association of baseline NLR with improved clinical response to filgotinib in MTX-naïve or MTX-experienced RA populations.

Genetic variants in TNFα, NLRP3, MYD88, and FcRγ genes were associated with a response to TNFi, when assessing several inflammatory diseases together. Al-Sofi et al. conducted a systematic review and meta-analysis on single nucleotide polymorphism (SNP) genetic markers and their response to biologics in psoriasis, PsA, RA, IBD, and across all chronic inflammatory diseases together.

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.

Goldman, et al. conducted a pharmacovigilance study to evaluate the cardiovascular safety of JAK inhibitors in RA patients. The study demonstrated an increase in the reporting of VTE, stroke, and ischemic heart disease in patients treated with JAK inhibitor compared to bDMARDs, especially within the first year of treatment. This suggests a class effect of JAK inhibitors on cardiovascular risk, emphasising the need for ongoing surveillance and proactive cardiovascular risk management.

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.
