Pfizer, Bristol-Myers announce results of subanalysis of Phase 3 ARISTOTLE trial

Bristol-Myers Squibb Company (BMY) and Pfizer (PFE) announced the results of a pre-specified subanalysis of the Phase 3 ARISTOTLE trial that assessed the effect of blood pressure control on outcomes as well as the treatment effect of Eliquis compared to warfarin according to blood pressure control.1 The results showed that poor blood pressure control was associated with a substantially higher risk of stroke or systemic embolism, independent of Eliquis or warfarin treatment. However, this subanalysis found consistent results for Eliquis versus warfarin in reducing the risk of stroke, regardless of blood pressure control. These data will be presented Saturday, March 29, at the American College of Cardiology’s 63rd Annual Scientific Session in Washington, D.C. In this subanalysis, the effect of Eliquis in reducing the risk of stroke and systemic embolism versus warfarin was consistent with the main results of the ARISTOTLE trial. Further, the effect of Eliquis in reducing the risk of stroke and systemic embolism versus warfarin was also consistent with the results of the ARISTOTLE trial in previously published subanalyses of other comorbidities, including congestive heart failure, advanced age, renal impairment and prior stroke. A total of 11 Bristol-Myers Squibb/Pfizer alliance-sponsored abstracts, including this ARISTOTLE subanalysis, were accepted for presentation at the American College of Cardiology’s 63rd Annual Scientific Session.
