Tofacitinib associated with reduced risk of developing ILD in patients with RA

Key clinical point: Patients with rheumatoid arthritis (RA) treated with tofacitinib had a 69% lower risk of developing interstitial lung disease (ILD) than those treated with adalimumab.

Major finding: Compared with adalimumab, tofacitinib resulted in the lowest incidence of ILD (incidence rate ratio 0.43; 95% CI 0.18-1.05), followed by abatacept, tocilizumab, and rituximab. Tofacitinib was associated with a significant 69% reduced risk of developing ILD compared with adalimumab (adjusted hazard ratio 0.31; P  =  .009).

Study details: Findings are from a retrospective cohort study including 28,559 patients with RA without preexisting ILD who were newly administered adalimumab, abatacept, rituximab, tocilizumab, or tofacitinib, of which 276 patients were diagnosed with incident ILD.
