AstraZeneca reports top-line results from the Brilinta SOCRATES trial in stroke

Missed primary efficacy endpoint; fewer events observed in the Brilinta arm but trend did not reach statistical significance.

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

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “We will present the full analysis of the trial results, including subgroups, at a forthcoming stroke congress and will engage with regulatory agencies on the interpretation of the data. The SOCRATES trial enrolled a patient population that differs from the currently-approved indications for Brilinta/Brilique.”

The SOCRATES trial evaluated the efficacy and safety of 90-day treatment with Brilinta/Brilique versus aspirin for the prevention of major vascular events in patients ≥40 years of age with an acute ischaemic stroke (National Institutes of Health Stroke Scale (NIHSS) ≤5) or TIA (ABCD2 score ≥4). Patients randomised into the trial needed to have symptom onset within 24 hours.

In the second half of 2016, data are expected from the ongoing EUCLID trial in peripheral arterial disease (PAD). EUCLID is the fourth trial to read-out from the PARTHENON programme, assessing the potential of Brilinta/Brilique in additional high-risk patient populations.
