(NYSE: AZN) today announced results from a PLATO sub-analysis that evaluated the effect of smoking status on clinical outcomes in patients with acute coronary syndrome (ACS). This analysis suggests the overall findings from the PLATO study of greater reduction in thrombotic CV events with BRILINTA (ticagrelor) tablets plus aspirin compared to clopidogrel plus aspirin was consistent regardless of smoking habits. These data, slated for publication in the September issue of , are currently available , and were previously presented at the American College of Cardiology 2012 meeting.

“The potential impact of smoking on the effect of certain medications continues to be a topic of considerable interest and discussion among the cardiovascular community,” stated James Ferguson, MD, Executive Director, Medical Affairs and Strategic Development, and Vice President for Global Medical Affairs. “This sub-analysis suggests that the clinical benefits of BRILINTA vs clopidogrel on thrombotic CV events shown in PLATO were not significantly affected by smoking status, and were similar in both smokers and non-smokers.”

BRILINTA is indicated to reduce the rate of thrombotic CV events in patients with acute coronary syndrome (ACS: unstable angina [UA], non–ST-elevation myocardial infarction [NSTEMI], or ST-elevation myocardial infarction [STEMI]). In PLATO, BRILINTA has been shown to reduce the rate of a combined end point of CV death, myocardial infarction (MI), or stroke compared to clopidogrel. In PLATO, the difference between treatments was driven by CV death and MI with no difference in stroke. In patients treated with an artery-opening procedure known as percutaneous coronary intervention (PCI), BRILINTA reduces the rate of stent thrombosis.

BRILINTA has been studied in ACS in combination with aspirin. Maintenance doses of aspirin above 100 mg decreased the effectiveness of BRILINTA. Avoid maintenance doses of aspirin above 100 mg daily.

The sub-analysis was conducted because habitual smoking has been associated with increased platelet reactivity, increased risk of thrombotic complications and greater efficacy of clopidogrel therapy over placebo.

Specific data from this sub-analysis showed:

The conclusion of the sub-analysis of PLATO suggests results of BRILINTA versus clopidogrel were consistent for thrombotic cardiovascular (CV) events in patients with Acute Coronary Syndrome (ACS) regardless of smoking status and that habitual smoking was associated with a greater risk of subsequent stent thrombosis.

For patients that require BRILINTA beyond their hospital stay, a savings card program is available based on eligibility. Commercially insured and cash-paying patients may be eligible for one free 30-day prescription and can save up to $825 per year on their next 11 refills. For each refill (a 30-day supply of up to 60 tablets), savings may apply after the first $18 spent by a patient, up to a $75 savings limit. Patients covered through Medicare, Medicaid or a similar federal or state program may be eligible for one month free prescription. Patients can find out more at or by calling 1-888-412-7454.

AstraZeneca also offers a U.S. patient assistance program for BRILINTA through its AZ&ME Prescription Savings Program. To determine eligibility, patients can visit or call 1-800-AZandMe (292-6363).

BRILINTA is an oral antiplatelet treatment for ACS. BRILINTA is a direct-acting P2Y receptor antagonist in a chemical class called cyclopentyltriazolopyrimidines (CPTPs). BRILINTA works by inhibiting platelet activation and has been shown to reduce the rate of thrombotic CV events, such as a heart attack or CV death, in patients with ACS.

BRILINTA is available in 90-mg tablets to be administered with a single 180-mg oral loading dose (two 90-mg tablets) followed by a twice daily, 90-mg maintenance dose. Following an initial loading dose of aspirin, BRILINTA should be used with a maintenance dose of 75 mg - 100 mg aspirin once daily, 81-mg aspirin dose in the US.

BRILINTA is a registered trademark of the AstraZeneca group of companies.

PLATO (PLATelet Inhibition and Patient Outcomes) was a large (18,624 patients in 43 countries), head-to-head patient outcomes study of BRILINTA versus clopidogrel, both given in combination with aspirin and other standard therapy. The study was designed to establish whether BRILINTA could achieve a clinically meaningful reduction in cardiovascular (CV) events in acute coronary syndrome (ACS) patients, above and beyond that afforded by clopidogrel. Patients were treated for at least 6 months and up to 12 months.

PLATO demonstrated that treatment with BRILINTA led to a significantly greater reduction in the primary end point – a composite of CV death, MI, or stroke – compared to patients who received clopidogrel (9.8% vs 11.7% at 12 months; 1.9% absolute risk reduction [ARR]; 16% relative risk reduction [RRR]; 95% CI, 0.77 to 0.92; <0.001). The difference in treatments was driven by CV death and MI with no difference in stroke. In PLATO, the absolute difference in treatment benefit versus clopidogrel was seen at 30 days and the Kaplan-Meier survival curves continued to diverge throughout the 12-month treatment period. The PLATO study also demonstrated that treatment with BRILINTA for 12 months was associated with a 21% RRR in CV death (4% vs 5.1%; 1.1% ARR; =0.001) and a 16% RRR in MI compared to clopidogrel at 12 months (5.8% vs 6.9%; 1.1% ARR; <0.005).

The primary safety end point in the PLATO study was Total Major Bleeding (11.6% for BRILINTA and 11.2% for clopidogrel). In PLATO, non-CABG major + minor bleeding events were more common with BRILINTA versus clopidogrel (8.7% vs 7% respectively). The rate of non-CABG-related major bleeding was higher for BRILINTA (4.5%) vs clopidogrel (3.8%).

Dyspnea was reported in 14% of patients treated with BRILINTA and in 8% of patients treated with clopidogrel. Dyspnea was usually mild to moderate in intensity and often resolved during continued treatment.

ACS is an umbrella term for conditions that result from insufficient blood supply to the heart muscle. These conditions range from unstable angina (UA), non–ST-elevation myocardial infarction (NSTEMI), or ST-elevation myocardial infarction (STEMI).
