New Perspectives in Rheumatology: Implications of the Cardiovascular Safety of Febuxostat and Allopurinol in Patients With Gout and Cardiovascular Morbidities Trial and the Associated Food and Drug Administration Public Safety Alert.
Recently, the US Food and Drug Administration (FDA) issued a public safety alert, responding to the results of the now-published Cardiovascular Safety of Febuxostat and Allopurinol in Patients With Gout and Cardiovascular Morbidities (CARES) trial. The CARES trial showed no significant difference between allopurinol and febuxostat in the primary composite end point of cardiovascular (CV) events in subjects with gout and established CV comorbidities at baseline. However, there was a significantly increased risk of CV and all-cause mortality with febuxostat. ⋯ The CARES trial results do not support first-line use of febuxostat ULT, and raise questions about febuxostat placement at various pharmacologic ULT decision tree branches. Alternatives to febuxostat that are frequently effective include allopurinol dose escalation and uricosuric therapy alone or combined with allopurinol. The FDA safety alert highlights the need for shared ULT medical decision-making with gout patients, including discussion of the CV safety of febuxostat.
