Other ORAL Surveillance subanalyses and tofacitinib real-world data reported
This was one of several analyses presented at ACR 2021 that compared adverse event risks for tofacitinib versus TNFi drugs. A separate analysis of claims data from patients with RA in two U.S. insurance databases plus Medicare found a statistically nonsignificant increased risk of adverse CV outcomes (MI or stroke) with tofacitinib, compared with TNFi users, among patients who met the same inclusion and exclusion criteria of the ORAL Surveillance trial but not in a “real-world evidence” cohort of more than 102,000 patients with RA in routine care from the databases.
Two additional ORAL Surveillance analyses presented at ACR 2021 gave details about risk factors for higher rates of malignancies and venous thromboembolic events found in patients taking tofacitinib with at least one CV risk factor. As would be expected, older age (≥65 vs. 50-64 years) and current or past smoking (vs. never smoking) were independent risk factors for higher malignancy rates across all treatment arms. Pulmonary embolism events across treatment groups were independently associated with a history of venous thromboembolism, baseline use of oral contraceptives or hormone replacement therapy, baseline body mass index of at least 30 kg/m2, age 65 or older, and history of hypertension.
The ORAL Surveillance findings are worth considering when determining treatments for RA patients with CV risk factors, Dr. Charles-Schoeman said. “Tofacitinib remains an effective RA treatment,” she said. “The choice of specific RA treatment for any patient remains an individual decision between the patient and physician, which is decided based on a number of different factors. This new study provides additional information regarding both tofacitinib as well as traditional CV risk factors for discussion with the patient.”
The ORAL Surveillance results may give rheumatologists reason to rethink use of tofacitinib in some patients with CV risk, said Dr. Liao of Brigham and Women’s Hospital in Boston. “Currently, we have limited data and are still awaiting a report of the full trial results,” she said in an interview. “Based on the data available, I can think of a few patients in my clinic where I would reconsider use of these drugs, i.e., history of heart attack with stable angina, especially if there are other options.” However, she noted that many patients on tofacitinib have already failed on older treatments.
These data emphasize the importance of addressing CV risk with patients, said Brittany N. Weber, MD, PhD, a cardio-rheumatologist at Brigham and Women’s Hospital who works with Dr. Liao. “It is also an opportunity to discuss modification of risk factors and to discuss primary prevention therapies, such as statin therapy, where appropriate,” she added. “Based on the individual’s cardiovascular risk, there may be a role for further risk stratification to further understand an individual’s risk, which can also inform primary prevention cardiovascular therapies and help guide these discussions.” Risk stratification could include cardiac CT for calcium scoring or cardiac coronary CT angiography for determining atherosclerotic burden.
The study was sponsored by Pfizer. Dr. Charles-Schoeman disclosed relationships with AbbVie, Bristol-Myers Squibb, Gilead Sciences, Pfizer, and Regeneron-Sanofi. Dr. Liao and Dr. Weber have no relevant disclosures.
