Unadjusted time to all-cause discontinuation was significantly longer with baricitinib treatment versus TNFi (estimated median prescription survival time of 704 days versus 448 days; log-rank P<0.01). This difference increased when only comparing differences for b/tsDMARD-naïve patients treated with baricitinib versus tofacitinib.

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.

Efficacy and safety of JAK inhibitors in rheumatoid arthritis: update for the practising clinician

Nat Rev Rheumatol 2024;20(2):101–115 DOI: 10.1038/s41584-023-01062-9

The observed benefit:risk ratio strongly favours JAKi use in the majority of patients, and HCPs should consider and adhere to guidance on high-risk patients where applicable. Szekanecz et al summarised the safety and efficacy of approved JAKis tofacitinib, baricitinib, upadacitinib, and filgotinib to aid in clinical decision making.

Effectiveness and Safety of Filgotinib in Rheumatoid Arthritis: A Real-life Multicentre Experience

Clin Exp Rheumatol 2024 doi 10.55563/clinexprheumatol/k78ug3 Epub ahead of print

This real-world observational study by La Barbera, et al. confirms that filgotinib is efficacious and safe for use in the management of RA. The authors also report that improvements in clinical and laboratory features were greater in bDMARD-naïve patients with RA.

This pooled analysis of four Phase 3 RCTs investigated the long-term efficacy baricitinib in patients with active RA who were MTX-IR, csDMARD-IR, or bDMARD-IR. They found that baricitinib demonstrated efficacy up to 6.5 years and was well tolerated.

Kwon, et al. found that adalimumab exposure significantly reduced risk of incident and recurrent acute anterior uveitis (AAU) versus etanercept exposure and bDMARD non-exposure. Furthermore, exposure to etanercept significantly increased risk of incident and recurrent AAU versus bDMARD non-exposure.

Effectiveness of Sequential Lines of Biologic and Targeted Small Molecule Drugs in Psoriatic Arthritis: A Systematic Review

Rheumatology (Oxford). 2024 Jan 18:keae006 doi: 10.1093/rheumatology/keae006 Epub ahead of print

The authors found that there is a reduction in effectiveness of lines of bDMARDs after first-line in PsA, with inadequate data to determine response to tsDMARDs.

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.
