Brilinta fails to demonstrate benefit over clopidogrel for peripheral artery disease patients in EUCLID trial


AstraZeneca has announced that top-line results from the EUCLID trial indicate that Brilinta (ticagrelor) did not demonstrate a benefit over clopidogrel in a symptomatic peripheral artery disease patient population and therefore did not meet the primary endpoint of the trial.

The EUCLID trial included 13,885 patients in 28 countries and is the largest cardiovascular outcomes trial to date conducted exclusively in symptomatic patients with peripheral artery disease. It evaluated the treatment of Brilinta 90mg tablets twice daily versus clopidogrel 75mg once daily for the prevention of atherothrombotic events (a composite of cardiovascular death, heart attack or ischaemic stroke). The primary endpoint of the trial was the time to first occurrence of any such event.

Based on preliminary analyses, safety data is consistent with the known safety profile of Brilinta.

Sean Bohen, executive vice president, Global Medicines Development and chief medical officer at AstraZeneca, said: “The proven benefits of Brilinta in acute coronary syndrome and post-myocardial infarction patients are established and remain unchanged. We are disappointed that the EUCLID trial results showed Brilinta did not demonstrate a benefit over clopidogrel in this specific symptomatic peripheral artery disease population.”
