180-mg loading dose

BRILIQUE (n=9,333)

*STEMI patients scheduled for primary PCI were randomised; however, they may not have received PCI.†A loading dose of 300-mg clopidogrel was permitted in patients not previously treated with clopidogrel,

with an additional 300 mg allowed at the discretion of the investigator.‡The PLATO study expanded the definition of major bleeding to be more inclusive compared with

previous studies in ACS patients. The primary safety endpoint was the first occurrence of any major bleeding event.

Randomisation

• All patients were hospitalised with symptom onset <24 hours• Patients could be taking clopidogrel at time of randomisation

PLATO: Study Design

PLATO Main: Inclusion Criteria

• Hospitalisation for STEMI or NSTEMI/UA ACS, with onset during previous 24 hours

• With STEMI, the following 2 inclusion criteria were required– Persistent ST elevation of at least 0.1 mV in ≥2 contiguous leads or new LBBB

– Primary PCI planned

• With NSTEMI, at least 2 of the following 3 were required– ST changes on ECG indicating ischaemia– Positive biomarker indicating myocardial necrosis– One of the following risk indicators

• ≥60 years of age• Previous MI or CABG• CAD with ≥50% stenosis in ≥2 vessels• Previous ischaemic stroke, TIA, carotid stenosis (≥50%), or cerebral

revascularisation• Diabetes mellitus• Peripheral artery disease• Chronic renal dysfunction (creatinine clearance <60 mL/min)

James S, et al. Am Heart J. 2009;157:599–605.

PLATO Main: Key Exclusion Criteria

• Contraindication to clopidogrel• Fibrinolytic therapy within 24 hours• Oral anticoagulation therapy that cannot be stopped• ACS event was a complication of previous PCI• PCI after index event (initial clinical signs and symptoms)

and before first study dose• Increased risk for bradycardic events• Concomitant therapy with strong CYP3A

inhibitors/inducers• Patients requiring dialysis

James S, et al. Am Heart J. 2009;157:599–605.

PLATO Study

Summary• PLATO (N Engl J Med. 2009;361:1045–1057) was a pivotal clinical

study, comparing BRILIQUE to clopidogrel• A total of 18,624 patients with ACS were randomised early after

admission to the hospital─within 24 hours of symptom onset and generally prior to angiography

• The study was designed to reflect clinical practice– Allowed prior clopidogrel use– Included both intent for invasive management (72%) and intent for

medical management (28%)– PLATO allowed up to 600-mg clopidogrel loading dose pre-PCI

• PLATO enrolled a broad spectrum of patients with ACS (UA, NSTEMI, or STEMI)

* Patients could have had more than one type of endpoint. Death from CV causes and fatal bleeding, as only traumatic fatal bleeds were excluded from the CV death category. ** By Cox regression analysis using treatment as factor; †Excluding silent MI; ‡Death from any cause was tested after stroke, which was non-significant, so the results should be considered nominally significant.

PLATO Efficacy Results

Summary• In PLATO, BRILIQUE significantly reduced the composite of CV

death, MI or stroke vs clopidogrel at 1 year (1.9% ARR, 16% RRR, P<0.001, NNT=54)

• BRILIQUE significantly reduced CV mortality vs clopidogrel (1.1% ARR, 21% RRR, P=0.001)– Risk of CV death and MI were both significantly reduced– Risk of stroke was not significantly different

• The absolute risk reduction with BRILIQUE vs clopidogrel starts early and continues to build over the full 1 year treatment period

• In PLATO, for every 91 ACS patients treated with BRILIQUE for 1 year, instead of clopidogrel, 1 CV death was prevented (NNT=91)

• The effect of BRILIQUE over clopidogrel appears consistent across many subgroups

PLATO: Dyspnoea

• BRILIQUE-associated dyspnoea was mostly mild to moderate in severity and did not reduce efficacy

• Most events were reported as single episode occurring early after starting treatment• Not associated with new or worsening heart or lung disease• In 2.2% of patients, investigators considered dyspnoea causally related to treatment

with BRILIQUE • Label precautions and warnings: use with caution in patients with history of asthma

and COPD

Appropriate Use of BRILIQUE

BRILIQUE Indication

• BRILIQUE, co-administered with acetylsalicylic acid (ASA), is indicated for the prevention of atherothrombotic events in adult patients with acute coronary syndromes (unstable angina, non–ST-elevation myocardial infarction [NSTEMI] or ST-elevation myocardial infarction [STEMI]); including patients managed medically, and those who are managed with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG)

BRILIQUE: Summary of Product Characteristics, 2010.

By Diagnosis By Treatment

UA/NSTEMI STEMI Medicalmanagement PCI CABG

If clinically indicated, BRILIQUE should be used with caution in the following patient groups: Patients with concomitant administration of medicinal products that may increase the risk of bleeding (eg, non-steroidal anti-inflammatory drugs (NSAIDs), oral anticoagulants and/or fibrinolytics) within 24 hours of BRILIQUE dosing

Contraindications

• Contraindications specific to BRILIQUE– Hypersensitivity to the active substance (BRILIQUE) or to any of

the excipients– Active pathological bleeding– History of intracranial haemorrhage– Moderate-to-severe hepatic impairment– Combination with strong CYP3A4 inhibitors such as

ketoconazole, clarithromycin, nefazodone, ritonavir and atazanavir is contraindicated, as co-administration may lead to substantial increases in exposure to BRILIQUE

BRILIQUE: Summary of Product Characteristics, 2010.

Special Warnings and Precautions

• Precautions specific to BRILIQUE– The use of BRILIQUE in patients at known increased risk for bleeding should be

balanced against the benefits– BRILIQUE should be discontinued 7 days prior to elective surgery– BRILIQUE should be used with caution in patients with a history of asthma

and/or COPD– BRILIQUE should be used with caution in patients at risk of bradycardic events– BRILIQUE should be used with caution in the following patient groups: patients

with concomitant administration of medicinal products that may increase the risk of bleeding (eg, non-steroidal anti-inflammatory drugs (NSAIDs), oral anticoagulants and/or fibrinolytics) within 24 hours of BRILIQUE dosing

– As a precautionary measure, the use of BRILIQUE in patients with uric acid nephropathy is discouraged

– Creatinine levels may increase during treatment with BRILIQUE – Renal function should be checked after 1 month and thereafter according to

routine medical practice– High maintenance dose of ASA (>300 mg) is not recommended– The concomitant use of BRILIQUE with doses of simvastatin >40 mg is not

recommended
