A population-based cohort study of 87,653 RA patients has found no evidence for an increased risk of venous thromboembolism (VTE) for tofacitinib, versus TNFis, in patients with RA. The introduction of JAKinibs, almost a decade ago, has provided an important oral option for the treatment of RA. However, in recent years, a safety concern, relating to incidence of VTE after treatment, has emerged. Consequently, both the US and European regulatory authorities now recommend caution for use of tofaci...

Comparative Risk of Venous Thromboembolism with Tofacitinib versus Tumour Necrosis Factor Inhibitor: A Cohort study of Rheumatoid Arthritis Patients

Occurrences of venous thromboembolism (VTE) in 50, 865 RA patients initiating Tofacitinib (TOF) or a TNF inhibitor (TNFi) was infrequent. No significant risk of VTE for TOF versus TNFi was observed. Safety concerns of JAK inhibitor BARI include potentially increased risk of VTE at the higher 4 mg dose. It’s unclear if this is attributable to JAK-inhibition and extends to TOF. This study compared the risk of VTE with TOF, versus TNFi in real-world settings with RA patients. RA patients in...

Cardiovascular Safety of Tocilizumab versus Tumor Necrosis Factor Inhibitors in Patients with Rheumatoid Arthritis – a Multi-database Cohort Study

Arthritis Rheumatol 2017 Feb 28. doi: 10.1002/art.40084

This multi-database population-based US cohort study found no evidence of an increased cardiovascular (CV) risk among RA patients who switched from a different biologic drug or tofacitinib to tocilizumab (TCZ) versus to a TNF inhibitor (TNFi). The study used claims data in patients with RA newly starting treatment with TCZ or a TNFi from three large databases: Medicare (n=7397), PharMetrics (n=8119) and MarketScan (n=12512). Included within the analysis were 9218 TCZ initiators propensity-score...
