FDA echoes EMA warning on tofacitinib after trial shows increased risk of CV events, cancer, thrombosis and death

The European and US drug regulators have both now issued warnings on the use of tofacitinib after final results from a large safety trial showed an increased risk of serious cardiovascular events, malignancy, thrombosis, and death.

Tofacitinib is approved for the treatment of moderate to severely active ulcerative colitis in patients who have had an inadequate response, lost response, or are intolerant to either conventional therapy or a biological agent. In June 2021, the European Medicines Agency (EMA) advised that in patients who are current or past smokers, or who have other cardiovascular and/or malignancy risk factors, tofacitinib should only be used to treat moderate or severe ulcerative colitis if no suitable treatment alternative is available.[39] This is in addition to its previous advice to use tofacitinib with caution in patients at high risk of blood clots and that patients aged >65 years should also only be treated with tofacitinib when there is no alternative treatment.[40]

The EMA advice followed final results from the clinical safety trial, which showed an increased risk of major cardiovascular events and cancer (excluding non-melanoma skin cancer) in patients with rheumatoid arthritis treated with tofacitinib, compared with patients treated with a tumour necrosis factor (TNF)-alpha inhibitor.[41]

The EMA advises clinicians to carefully evaluate the patient’s individual benefit-risk profile when deciding to start or continue treatment with tofacitinib.[39]

In September 2021, a similar safety alert has been issued by the US Food and Drug Administration (FDA) for tofacitinib and two other Janus kinase (JAK) inhibitors (baricitinib and upadacitinib), based on results from the same study. The FDA warns about an increased risk of serious cardiovascular events, malignancy, thrombosis, and death with these agents. The FDA advises clinicians to reserve tofacitinib, baricitinib, and upadacitinib for patients who have had an inadequate response or are intolerant to one or more TNF-alpha inhibitors and to consider the patient’s individual benefit-risk profile when deciding to prescribe or continue treatment with these medications, particularly in patients who are current or past smokers, patients with other cardiovascular risk factors, those who develop a malignancy, and those with a known malignancy (other than a successfully treated non-melanoma skin cancer).[42]
