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.

The RCTs included in the study were FINCH 1, FINCH 2, and FINCH 3. These studies investigated the efficacy of filgotinib in RA patients, while FINCH 1 also investigated the efficacy of adalimumab. Retrospective claims-based switching data were also reviewed.
