Large Real-World Study Finds No Increased Cancer or Cardiovascular Risk with JAK Inhibitors in Rheumatoid Arthritis
- A comprehensive analysis of 53,169 treatment initiations across 13 international registries found no significantly higher cancer risk in rheumatoid arthritis patients treated with JAK inhibitors compared to biologic DMARDs.
- Separate cardiovascular safety data from 51,233 patients showed JAK inhibitors did not increase major adverse cardiovascular events compared to TNF inhibitors, with rates of 6.97 versus 7.57 per 1,000 person-years respectively.
- The findings provide reassuring real-world evidence addressing previous safety concerns raised by the ORAL Surveillance trial, though increased keratinocyte cancer risk remains a consideration for JAK inhibitor therapy.
- GLP-1 receptor agonists showed potential cardioprotective effects in RA patients on JAK inhibitors, with significantly lower rates of acute coronary syndromes and deep venous thrombosis.
