RA: No increased risk for malignancy with tofacitinib vs. TNFi in real world

Key clinical point: This real-world study found no evidence of increased risk for malignancy in patients with rheumatoid arthritis (RA) who initiated tofacitinib vs. tumor necrosis factor inhibitors (TNFi).

Major finding: The risk for cumulative malignancies in patients who initiated tofacitinib vs. TNFi was not higher in the real-world evidence (RWE) cohort (pooled weighted hazard ratio [pwHR] 1.01; 95% CI 0.83-1.22), but was numerically higher in the randomized controlled trial (RCT)-duplicate cohort of patients aged ≥50 years with at least one cardiovascular risk factor (pwHR 1.17; 95% CI 0.85-1.62).

Study details: This was a population-based observational, STAR-RA, study including 83,295 patients in the RWE cohort and 27,035 patients in the RCT-duplicate cohort who initiated tofacitinib or TNFi.
