Key clinical point: Clinicians should exercise caution when prescribing antiplatelet and anticoagulant medications in people taking the Bruton tyrosine kinase inhibitor ibrutinib.
Major finding: The use of both antiplatelet and anticoagulant therapy significantly increased the risk of a major bleed event (HR, 19.2; 95% CI, 2.3-166.7; P less than .01) in patients also taking ibrutinib.
Study details: A retrospective analysis of prescription data from 70 patients seen at a single U.S. cancer center and its regional clinics between January 2012 and May 2016.
Disclosures: Two of the authors reported receiving clinical trial support from Acerta and Abbvie.
