Filgotinib Demonstrates Efficacy in Rheumatoid Arthritis Independent of Smoking Status: Post Hoc Analysis of Phase 3 Trials and Claims-Based Analysis)
Rheumatol Ther 2023;11(1):177–189 doi 10.1007/s40744-023-00619-0
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.
Diminished cytokine-induced Jak/STAT signaling is associated with rheumatoid arthritis and disease activity
PLoS ONE 2021;16(1):e0244187This analysis provides evidence that immune cell signalling pathways are important in RA. There were consistent differences between RA patients and healthy controls in IFNα, IL-6, IL-10 and GM-CSF+ IL-2 induced JAK/STAT signalling in multiple immune cell subsets.We know that RA is characterised by dysregulation of immune responses, but the exact cause is unknown. Recently, single-cell transcriptomics and mass cytometry confirmed the critical role of activated immune cells and fibroblasts, increa...
