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.

This study by Cho, et al. did not find any significant differences in remission rates in South Korean patients with RA that were treated with tofacitinib versus TNFi in a real-world setting. Remission rates were significantly higher for patients naïve to both JAKi and bDMARDs treated with tofacitinib versus TNFi.

Cardiovascular Safety of Janus Kinase Inhibitor Therapy in a Multi-ethnic Population

Musculoskeletal Care 2023 doi 10.1002/msc.1853 Epub ahead of print

This study by Sunmboye, et al. investigated the relationship between CV event incidence and age in a multi-ethnic population that received JAK inhibitor therapy. They concluded that JAK inhibitor therapy was generally safe in a multi-ethnic population with a large age range, but they did find a statistically significant but numerically small positive correlation between age and CV incidence

This post hoc analysis by Curtis, et al. found that current and former smokers were more likely to switch from an anti-TNF bDMARD to a different bDMARD or JAK inhibitor in comparison to non-smokers. They also found that DAS28(CRP) ≤3.2 achievement was significantly higher after filgotinib therapy regardless of smoking status in MTX-IR, bDMARD-IR, and MTX-naïve patients.
