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

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.

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.

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.

Bimekizumab was well tolerated in patients with PsA and TNFi-IR up to 52 weeks, with a safety profile consistent with that observed in prior studies. This study aimed to assess 52-week safety and efficacy of bimekizumab in patients with active PsA and prior IR/intolerance to TNFi.

Data from this phase 3 RCT demonstrated that the efficacy of bimekizumab observed at 16 weeks remained consistent through to 52 weeks in the treatment of bDMARD-naïve patients with PsA. Patients who started the trial on placebo and switched to bimekizumab at week 16 showed similar improvements to those patients who were randomised to receive bimekizumab at the start of the trail. No new safety signals were identified.

Findings from post hoc analyses extend the knowledge base for radiographic benefits of filgotinib in patients with RA.

This study by Tanaka, et al. shows that filgotinib reduces peripheral protein biomarkers associated with JAK/STAT signalling, inflammatory signalling, immune cell migration, and bone resorption in RA patients. Notably, filgotinib 200 mg significantly reduced IL-6, TNF, CXCL13 levels as early as Week 4.
