PosologyBrilique treatment should be initiated with a single 180 mg loading dose (two tablets of 90 mg) and then continued at 90 mg twice daily.Patients taking Brilique should also take ASA daily, unless specifically contraindicated. Following an initial dose of ASA, Brilique should be used with a maintenance dose of ASA of 75-150 mg (see section 5.1).Treatment is recommended for up to 12 months unless discontinuation of Brilique is clinically indicated (see section 5.1). Experience beyond 12 months is limited.In patients with Acute Coronary Syndromes (ACS), premature discontinuation with any antiplatelet therapy, including Brilique, could result in an increased risk of cardiovascular death, or myocardial infarction due to the patient's underlying disease. Therefore, premature discontinuation of treatment should be avoided.Lapses in therapy should also be avoided. A patient who misses a dose of Brilique should take only one 90 mg tablet (their next dose) at its scheduled time.Patients treated with clopidogrel can be directly switched to Brilique if needed (see section 5.1). Switching from prasugrel to Brilique has not been investigated.
Older peopleNo dose adjustment is required in elderly (see section 5.2).
Patients with renal impairmentNo dose adjustment is necessary for patients with renal impairment (see section 5.2). No information is available concerning treatment of patients on renal dialysis and therefore Brilique is not recommended in these patients.
Patients with hepatic impairmentNo dose adjustment is necessary for patients with mild hepatic impairment. Brilique has not been studied in patients with moderate or severe hepatic impairment. Its use in patients with moderate to severe hepatic impairment is therefore contraindicated (see section 4.3, 4.4 and 5.2).
Paediatric populationThe safety and efficacy of Brilique in children below the age of 18 in the approved adult indication has not been established. No data are available (see section 5.1 and 5.2).
Method of administrationFor oral use. Brilique can be administered with or without food.
Bleeding riskIn the phase 3 pivotal trial (PLATO [PLATelet Inhibition and Patient Outcomes], 18,624 patients) key exclusion criteria included an increased risk for bleeding, clinically important thrombocytopenia or anaemia, previous intracranial bleed, gastrointestinal bleed within the past 6 months or major surgery within the past 30 days. Patients with acute coronary syndromes treated with Brilique and ASA showed an increased risk of non-CABG major bleeding and also more generally in bleeds requiring medical attention i.e. Major + Minor PLATO bleeds, but not Fatal or Life-threatening bleeds (see section 4.8).Therefore, the use of Brilique in patients at known increased risk for bleeding should be balanced against the benefit in terms of prevention of atherothrombotic events. If clinically indicated, Brilique should be used with caution in the following patient groups:• Patients with a propensity to bleed (e.g. due to recent trauma, recent surgery, coagulation disorders, active or recent gastrointestinal bleeding). The use of Brilique is contraindicated in patients with active pathological bleeding, in those with a history of intracranial haemorrhage, and in patients with moderate to severe hepatic impairment (see section 4.3).• Patients with concomitant administration of medicinal products that may increase the risk of bleeding (e.g. non-steroidal anti-inflammatory drugs (NSAIDs), oral anticoagulants and/or fibrinolytics) within 24 hours of Brilique dosing.No data exist with Brilique regarding a haemostatic benefit of platelet transfusions; circulating Brilique may inhibit transfused platelets. Since co-administration of Brilique with desmopressin did not decrease template-bleeding time, desmopressin is unlikely to be effective in managing clinical bleeding events (see section 4.5).Antifibrinolytic therapy (aminocaproic acid or tranexamic acid) and/or recombinant factor VIIa may increase haemostasis. Brilique may be resumed after the cause of bleeding has been identified and controlled.
SurgeryPatients should be advised to inform physicians and dentists that they are taking Brilique before any surgery is scheduled and before any new medicinal product is taken.In PLATO patients undergoing coronary artery bypass grafting (CABG), Brilique had more bleeding than clopidogrel when stopped within 1 day prior to surgery but a similar rate of major bleeds compared to clopidogrel after stopping therapy 2 or more days before surgery (see section 4.8). If a patient is to undergo elective surgery and antiplatelet effect is not desired, Brilique should be discontinued 7 days prior to surgery (see section 5.1).
Patients at risk for bradycardic eventsDue to observations of mostly asymptomatic ventricular pauses in an earlier clinical study, patients with an increased risk of bradycardic events (e.g. patients without a pacemaker who have sick sinus syndrome, 2nd or 3rd degree AV block or bradycardic-related syncope) were excluded from the main PLATO study evaluating the safety and efficacy of Brilique. Therefore, due to the limited clinical experience, Brilique should be used with caution in these patients (see section 5.1).In addition, caution should be exercised when administering Brilique concomitantly with medicinal products known to induce bradycardia. However no evidence of clinically significant adverse reactions was observed in the PLATO trial after concomitant administration with one or more medicinal products known to induce bradycardia (e.g., 96% beta blockers, 33% calcium channel blockers diltiazem and verapamil, and 4% digoxin) (see section 4.5).During the Holter substudy in PLATO, more patients had ventricular pauses >3 seconds with ticagrelor than with clopidogrel during the acute phase of their ACS. The increase in Holter-detected ventricular pauses with ticagrelor was higher in patients with chronic heart failure (CHF) than in the overall study population during the acute phase of ACS, but not at one month with ticagrelor or compared to clopidogrel. There were no adverse clinical consequences associated with this imbalance (including syncope or pacemaker insertion) in this patient population (see section 5.1).
DyspnoeaDyspnoea was reported by 13.8% of patients treated with Brilique and by 7.8% of patients treated with clopidogrel. In 2.2% of patients, investigators considered the dyspnoea causally related to treatment with Brilique. It is usually mild to moderate in intensity and often resolves without need for treatment discontinuation. Patients with asthma/COPD may have an increased absolute risk of experiencing dyspnoea with Brilique (see section 4.8). Ticagrelor should be used with caution in patients with history of asthma and/or COPD. The mechanism has not been elucidated. If a patient reports new, prolonged or worsened dyspnoea this should be investigated fully and if not tolerated, treatment with Brilique should be stopped.
Creatinine elevationsCreatinine levels may increase during treatment with Brilique (see section 4.8). The mechanism has not been elucidated. Renal function should be checked after one month and thereafter according to routine medical practice, paying special attention to patients ≥ 75 years, patients with moderate/severe renal impairment and those receiving concomitant treatment with an ARB.
Uric acid increaseIn PLATO study, patients on ticagrelor had a higher risk of hyperuricaemia than those patients receiving clopidogrel (see section 4.8). Caution should be exercised when administering ticagrelor to patients with history of hyperuricaemia or gouty arthritis. As a precautionary measure, the use of ticagrelor in patients with uric acid nephropathy is discouraged.
OtherBased on a relationship observed in PLATO between maintenance ASA dose and relative efficacy of ticagrelor compared to clopidogrel, co-administration of Brilique and high maintenance dose ASA (>300 mg) is not recommended (see section 5.1).Co-administration of Brilique with strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin, nefazodone, ritonavir, and atazanavir) is contraindicated (see section 4.3 and 4.5). Co-administration may lead to a substantial increase in Brilique exposure (see section 4.5).Co-administration of ticagrelor with strong CYP3A4 inducers (e.g. rifampicin, dexamethasone, phenytoin, carbamazepine and phenobarbital) is discouraged, as co-administration may lead to a decrease in exposure and efficacy of ticagrelor (see section 4.5).Co-administration of Brilique and CYP3A4 substrates with narrow therapeutic indices (i.e., cisapride and ergot alkaloids) is not recommended, as ticagrelor may increase the exposure to these medicinal products (see section 4.5). The concomitant use of Brilique with doses of simvastatin or lovastatin greater than 40 mg is not recommended (see section 4.5).Close clinical and laboratory monitoring is recommended when giving digoxin concomitantly with Brilique (see section 4.5).No data are available on concomitant use of Brilique with verapamil and quinidine, drugs that are potent P-glycoprotein (P-gp) inhibitors and moderate CYP3A4 inhibitors which may increase ticagrelor exposure. If the association cannot be avoided, their concomitant use should be made with caution (see section 4.5).
Effects of other medicinal products on Brilique
Medicinal products metabolised by CYP3A4
CYP3A4 inhibitors• Strong CYP3A4 inhibitors Co-administration of ketoconazole with ticagrelor increased the ticagrelor Cmax and AUC equal to 2.4-fold and 7.3-fold, respectively. The Cmax and AUC of the active metabolite were reduced by 89% and 56%, respectively. Other strong inhibitors of CYP3A4 (clarithromycin, nefazodone, ritonavir, and atazanavir) would be expected to have similar effects and their concomitant use with Brilique is contraindicated (see section 4.3 and 4.4).• Moderate CYP3A4 inhibitors Co-administration of diltiazem with ticagrelor increased the ticagrelor Cmax by 69% and AUC to 2.7 fold and decreased the active metabolite Cmax by 38% and AUC was unchanged. There was no effect of ticagrelor on diltiazem plasma levels. Other moderate CYP3A4 inhibitors (e.g. amprenavir, aprepitant, erythromycin and fluconazole) would be expected to have a similar effect and can as well be co-administered with Brilique.
CYP3A inducersCo-administration of rifampicin with ticagrelor decreased ticagrelor Cmax and AUC by 73% and 86%, respectively. The Cmax of the active metabolite was unchanged and the AUC was decreased by 46%, respectively. Other CYP3A inducers (e.g. dexamethasone, phenytoin, carbamazepine and phenobarbital) would be expected to decrease the exposure to Brilique as well. Co-administration of ticagrelor with potent CYP3A inducers may decrease exposure and efficacy of ticagrelor (see section 4.4).
Cyclosporine (P-gp and CYP3A inhibitor)Co-administration of cyclosporine (600 mg) with ticagrelor increased ticagrelor Cmax and AUC equal to 2.3-fold and 2.8-fold, respectively. The AUC of the active metabolite was increased by 32% and Cmax was decreased by 15% in the presence of cyclosporine. No data are available on concomitant use of Brilique with other drugs that also are potent P-glycoprotein (P-gp) inhibitors and moderate CYP3A4 inhibitors (e.g. verapamil, quinidine) that also may increase ticagrelor exposure. If the association cannot be avoided, their concomitant use should be made with caution (see section 4.4).
OthersClinical pharmacology interaction studies showed that co-administration of ticagrelor with heparin, enoxaparin and ASA or desmopressin did not have any effect on the pharmacokinetics of ticagrelor or the active metabolite or on ADP-induced platelet aggregation compared with ticagrelor alone. If clinically indicated, medicinal products that alter haemostasis should be used with caution in combination with Brilique (see section 4.4).A 2-fold increase of ticagrelor exposure was observed after daily consumption of large quantities of grapefruit juice (3x 200ml). This magnitude of increased exposure is not expected to be clinically relevant to most patients.
Effects of Brilique on other medicinal products
Medicinal products metabolised by CYP3A4• Simvastatin Co-administration of ticagrelor with simvastatin increased simvastatin Cmax by 81% and AUC by 56% and increased simvastatin acid Cmax by 64% and AUC by 52% with some individual increases equal to 2 to 3 fold. Co-administration of ticagrelor with doses of simvastatin exceeding 40 mg daily could cause adverse effects of simvastatin and should be weighed against potential benefits. There was no effect of simvastatin on ticagrelor plasma levels. Brilique may have similar effect on lovastatin. The concomitant use of Brilique with doses of simvastatin or lovastatin greater than 40 mg is not recommended (see section 4.4).• Atorvastatin - Co-administration of atorvastatin and ticagrelor increased atorvastatin acid Cmax by 23% and AUC by 36%. Similar increases in AUC and Cmax were observed for all atorvastatin acid metabolites. These increases are not considered clinically significant.• A similar effect on other statins metabolised by CYP3A4 cannot be excluded. Patients in PLATO receiving ticagrelor took a variety of statins, with no concern of an association with statin safety among the 93% of the PLATO cohort taking these medicinal products. Ticagrelor is a mild CYP3A4 inhibitor. Co-administration of Brilique and CYP3A4 substrates with narrow therapeutic indices (i.e., cisapride or ergot alkaloids) is not recommended, as ticagrelor may increase the exposure to these medicinal products (see section 4.4).
Medicinal products metabolised by CYP2C9Co-administration of Brilique with tolbutamide resulted in no change in the plasma levels of either medicinal product, which suggest that ticagrelor is not a CYP2C9 inhibitor and unlikely to alter the CYP2C9 mediated metabolism of medicinal products like warfarin and tolbutamide.Oral contraceptivesCo-administration of Brilique and levonorgestrel and ethinyl estradiol increased ethinyl estradiol exposure approximately 20% but did not alter the pharmacokinetics of levonorgestrel. No clinically relevant effect on oral contraceptive efficacy is expected when levonorgestrel and ethinyl estradiol are co-administered with Brilique.
P-glycoprotein (P-gp) substrates (including digoxin, cyclosporine)Concomitant administration of Brilique increased the digoxin Cmax by 75% and AUC by 28%. The mean trough digoxin levels were increased about 30% with ticagrelor co-administration with some individual maximum increases to 2 fold. In the presence of digoxin, the Cmax and AUC of ticagrelor and its active metabolite were not affected. Therefore, appropriate clinical and/or laboratory monitoring is recommended when giving narrow therapeutic index P-gp dependent medicinal products like digoxin concomitantly with Brilique (see section 4.4).There was no effect of ticagrelor on cyclosporine blood levels. Effect of ticagrelor on other P-gp substrates has not been studied.
Other concomitant therapy
Medicinal products known to induce bradycardiaDue to observations of mostly asymptomatic ventricular pauses and bradycardia, caution should be exercised when administering Brilique concomitantly with medicinal products known to induce bradycardia (see section 4.4). However no evidence of clinically significant adverse reactions was observed in the PLATO trial after concomitant administration with one or more medicinal products known to induce bradycardia (e.g., 96% beta blockers, 33% calcium channel blockers diltiazem and verapamil, and 4% digoxin).In the PLATO study, Brilique was commonly administered with ASA, proton pump inhibitors, statins, beta-blockers, angiotensin converting enzyme inhibitors and angiotensin receptor blockers as needed for concomitant conditions for long-term and also heparin, low molecular weight heparin and intravenous GpIIb/IIIa inhibitors for short durations (see section 5.1). No evidence of clinically significant adverse interactions with these medicinal products was observed.Co-administration of Brilique with heparin, enoxaparin or desmopressin had no effect on activated partial thromboplastin time (aPTT), activated coagulation time (ACT) or factor Xa assays. However, due to potential pharmacodynamic interactions, caution should be exercised with the concomitant administration of Brilique with medicinal products known to alter haemostasis (see section 4.4).Due to reports of cutaneous bleeding abnormalities with SSRIs (e.g., paroxetine, sertraline and citalopram), caution is advised when administering SSRIs with Brilique as this may increase the risk of bleeding.
Women of childbearing potentialWomen of childbearing potential should use appropriate contraceptive measures to avoid pregnancy during Brilique therapy.
PregnancyThere are no or limited amount of data from the use of ticagrelor in pregnant women. Studies in animals have shown reproductive toxicity (see section 5.3). Brilique is not recommended during pregnancy.
BreastfeedingAvailable pharmacodynamic/toxicological data in animals have shown excretion of ticagrelor and its active metabolites in milk (see section 5.3). A risk to newborns/infants cannot be excluded. A decision must be made whether to discontinue breastfeeding or to discontinue/abstain from Brilique therapy taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.
FertilityTicagrelor had no effect on male or female fertility in animals (see section 5.3).
Summary of the safety profileThe safety of Brilique in patients with acute coronary syndromes (UA, NSTEMI and STEMI) was evaluated in the pivotal large phase 3 PLATO ([PLATelet Inhibition and Patient Outcomes] study, 18,624 patients), which compared patients treated with Brilique (loading dose of 180 mg of Brilique and a maintenance dose of 90 mg twice daily) to patients treated with clopidogrel (300-600 mg loading dose followed by 75 mg once daily maintenance dose) both given in combination with acetylsalicylic acid (ASA) and other standard therapies.The most commonly reported adverse reactions in patients treated with ticagrelor were dyspnoea, contusion and epistaxis and these reactions occurred at higher rates than in the clopidogrel treatment group.

DyspnoeaDyspnoea, a sensation of breathlessness, is reported by patients treated with Brilique. Dyspnoea adverse events (AEs) (dyspnoea, dyspnoea at rest, dyspnoea exertional, dyspnoea paroxysmal nocturnal and nocturnal dyspnoea), when combined, was reported by 13.8% of patients treated with ticagrelor and by 7.8% of patients treated with clopidogrel. In 2.2% of patients taking ticagrelor and by 0.6% taking clopidogrel investigators considered the dyspnoea causally related to treatment in the PLATO study and few were serious (0.14% ticagrelor; 0.02% clopidogrel), (see section 4.4). Most reported symptoms of dyspnoea were mild to moderate in intensity, and most were reported as a single episode early after starting treatment. Compared with clopidogrel, patients with asthma/COPD treated with ticagrelor may have an increased risk of experiencing non-serious dyspnoea (3.29% ticagrelor versus 0.53% clopidogrel) and serious dyspnoea (0.38% ticagrelor versus 0.00% clopidogrel). In absolute terms, this risk was higher than in the overall PLATO population. Ticagrelor should be used with caution in patients with history of asthma and/or COPD (see section 4.4).About 30% of episodes resolved within 7 days. PLATO included patients with baseline congestive heart failure, chronic obstructive pulmonary disease, or asthma; these patients, and the elderly, were more likely to report dyspnoea. For Brilique, 0.9% of patients discontinued study drug because of dyspnoea compared with 0.1% taking clopidogrel. The higher incidence of dyspnoea with Brilique is not associated with new or worsening heart or lung disease (see section 4.4). Brilique does not affect tests of pulmonary function.
InvestigationsCreatinine elevations: In PLATO, serum creatinine concentration significantly increased by >30% in 25.5% of patients receiving ticagrelor compared to 21.3% of patients receiving clopidogrel and by >50% in 8.3% of patients receiving ticagrelor compared to 6.7% of patients receiving clopidogrel. Creatinine elevations by >50% were more pronounced in patients > 75 years (ticagrelor 13.6% versus clopidogrel 8.8%), in patients with severe renal impairment at baseline (ticagrelor 17.8% versus clopidogrel 12.5%) and in patients receiving concomitant treatment with ARBs (ticagrelor 11.2% versus clopidogrel 7.1%). Within these subgroups renal-related serious adverse events and adverse events leading to discontinuation of study drug were similar between treatment groups. The totality of renal AEs reported were 4.9% for ticagrelor vs. 3.8% for clopidogrel, however a similar percent of patients reported events considered by the investigators as causally related to treatment; 54 (0.6%) for ticagrelor and 43 (0.5%) for clopidogrel.Uric acid elevations: In PLATO, serum uric acid concentration increased to more than upper limit of normal in 22% of patients receiving ticagrelor compared to 13% of patients receiving clopidogrel. Mean serum uric acid concentration increased approximately 15% with ticagrelor compared to approximately 7.5% with clopidogrel and after treatment was stopped, decreased to approximately 7% on ticagrelor but with no decrease observed for clopidogrel. The hyperuricaemia AEs reported were 0.5% for ticagrelor vs. 0.2% for clopidogrel. Of these AEs 0.05% for ticagrelor vs. 0.02% for clopidogrel were considered causally related by investigators. For gouty arthritis, the AEs reported were 0.2% for ticagrelor vs 0.1% for clopidogrel; none of these adverse events were assessed as causally related by investigators.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via:

Mechanism of actionBrilique contains ticagrelor a member of the chemical class cyclopentyltriazolopyrimidines (CPTP), which is a selective adenosine diphosphate (ADP) receptor antagonist acting on the P2Y12 ADP-receptor that can prevent ADP-mediated platelet activation and aggregation. Ticagrelor is orally active, and reversibly interacts with the platelet P2Y12 ADP-receptor. Ticagrelor does not interact with the ADP binding site itself, but interacts with platelet P2Y12 ADP-receptor to prevent signal transduction.
Onset of ActionIn patients with stable coronary artery disease on ASA, ticagrelor demonstrates a rapid onset of pharmacological effect as demonstrated by a mean Inhibition of Platelet Aggregation (IPA) for ticagrelor at 0.5 hours after 180 mg loading dose of about 41%, with the maximum IPA effect of 89% by 2-4 hours post dose, and maintained between 2-8 hours. 90% of patients had final extent IPA >70% by 2 hours post dose.
Offset of ActionIf a CABG procedure is planned, ticagrelor bleeding risk is increased compared to clopidogrel when discontinued within less than 96 hours prior to procedure.
Switching dataSwitching from clopidogrel to ticagrelor results in an absolute IPA increase of 26.4% and switching from ticagrelor to clopidogrel results in an absolute IPA decrease of 24.5%. Patients can be switched from clopidogrel to ticagrelor without any interruption of antiplatelet effect (see section 4.2).
Clinical efficacy and safetyThe PLATO study included 18,624 patients who presented within 24 hours of onset of symptoms of unstable angina (UA), non ST elevation myocardial infarction (NSTEMI) or ST elevation myocardial infarction (STEMI), and were initially managed medically, or with percutaneous coronary intervention (PCI), or with coronary artery bypass grafting (CABG) (see section 4.1).On a background of daily ASA, ticagrelor 90 mg twice daily showed superiority to 75 mg daily clopidogrel in preventing the composite endpoint of cardiovascular [CV] death, myocardial infarction [MI], or stroke, with the difference driven by CV death and MI. Patients received a 300 mg loading dose of clopidogrel (600 mg possible if having PCI) or 180 mg of ticagrelor.The result appeared early (absolute risk reduction [ARR] 0.6% and Relative Risk Reduction [RRR] of 12% at 30 days), with a constant treatment effect over the entire 12 month period, yielding ARR 1.9% per year with RRR of 16%. This suggests it is appropriate to treat patients with ticagrelor for up to 12 months (see section 4.2). Treating 54 ACS patients with ticagrelor instead of clopidogrel will prevent 1 atherothrombotic event; treating 91 will prevent 1 CV death (see Figure 1 and Table 3).The treatment effect of ticagrelor over clopidogrel appears consistent across many subgroups, including weight; sex; medical history of diabetes mellitus, transient ischaemic attack or non-haemorrhagic stroke, or revascularisation; concomitant therapies including heparins, GpIIb/IIIa inhibitors and proton pump inhibitors (see section 4.5); final index event diagnosis (STEMI, NSTEMI, or UA); and, treatment pathway intended at randomisation (invasive or medical).A weakly significant treatment interaction was observed with region whereby the HR for the primary endpoint favours ticagrelor in the rest of world but favours clopidogrel in North America, which represented approximately 10% of the overall population studied (interaction p-value=0.045). Exploratory analyses suggest a possible association with ASA dose such that reduced efficacy was observed with ticagrelor with increasing ASA doses. Chronic daily ASA doses to accompany Brilique should be 75-150 mg (see section 4.2 and 4.4).Figure 1 shows the estimate of the risk to the first occurrence of any event in the composite efficacy endpoint.
Figure 1 Time to first occurrence of CV death, MI and Stroke (PLATO)Brilique reduced the occurrence of the primary composite endpoint compared to clopidogrel in both the UA/NSTEMI and STEMI population (Table 3).

Holter SubstudyTo study the occurrence of ventricular pauses and other arrhythmic episodes during PLATO, investigators performed Holter monitoring in a subset of nearly 3000 patients, of whom approximately 2000 had recordings both in the acute phase of their ACS and after one month. The primary variable of interest was the occurrence of ventricular pauses ≥3 seconds. More patients had ventricular pauses with ticagrelor (6.0%) than with clopidogrel (3.5%) in the acute phase; and 2.2% and 1.6% respectively after 1 month (see section 4.4). The increase in ventricular pauses in the acute phase of ACS was more pronounced in ticagrelor patients with history of CHF (9.2% versus 5.4% in patients without CHF history; for clopidogrel patients, 4.0% in those with versus 3.6% in those without CHF history) This imbalance did not occur at one month: 2.0% versus 2.1% for ticagrelor patients with and without CHF history respectively; and 3.8% versus 1.4% with clopidogrel. There were no adverse clinical consequences associated with this imbalance (including pacemaker insertions) in this population of patients.
PLATO genetic substudyCYP2C19 and ABCB1 genotyping of 10,285 patients in PLATO provided associations of genotype groups with PLATO outcomes. The superiority of ticagrelor over clopidogrel in reducing major CV events was not significantly affected by patient CYP2C19 or ABCB1 genotype. Similar to the overall PLATO study, total PLATO Major bleeding did not differ between ticagrelor and clopidogrel, regardless of CYP2C19 or ABCB1 genotype. Non-CABG PLATO Major bleeding was increased with ticagrelor compared clopidogrel in patients with one or more CYP2C19 loss of function alleles, but similar to clopidogrel in patients with no loss of function allele.
Combined efficacy and safety compositeA combined efficacy and safety composite (CV death, MI, stroke, or PLATO-defined 'Total Major' bleeding) indicates that the benefit in efficacy of Brilique compared to clopidogrel is not offset by the major bleeding events (ARR 1.4%, RRR 8%, HR 0.92; p=0.0257) over 12 months after ACS.
Paediatric populationThe European Medicines Agency has waived the obligation to submit the results of studies with Brilique in all subsets of the paediatric population in the granted indication (see section 4.2 and 5.2).
AbsorptionAbsorption of ticagrelor is rapid with a median tmax of approximately 1.5 hours. The formation of the major circulating metabolite AR-C124910XX (also active) from ticagrelor is rapid with a median tmax of approximately 2.5 hours. Following oral administration of ticagrelor 90 mg under fasted conditions, Cmax is 529 ng/ml and AUC is 3451 ng*h/ml. The metabolite parent ratios are 0.28 for Cmax and 0.42 for AUC.The mean absolute bioavailability of ticagrelor was estimated to be 36%. Ingestion of a high-fat meal resulted in a 21% increase in ticagrelor AUC and 22% decrease in the active metabolite Cmax but had no effect on ticagrelor Cmax or the AUC of the active metabolite. These small changes are considered of minimal clinical significance; therefore, ticagrelor can be given with or without food. Ticagrelor as well as the active metabolite are P-gp substrates.
DistributionThe steady state volume of distribution of ticagrelor is 87.5 l. Ticagrelor and the active metabolite is extensively bound to human plasma protein (>99.0%).
BiotransformationCYP3A4 is the major enzyme responsible for ticagrelor metabolism and the formation of the active metabolite and their interactions with other CYP3A substrates ranges from activation through to inhibition. The major metabolite of ticagrelor is AR-C124910XX, which is also active as assessed by in vitro binding to the platelet P2Y12 ADP-receptor. The systemic exposure to the active metabolite is approximately 30-40% of that obtained for ticagrelor.
EliminationThe primary route of ticagrelor elimination is via hepatic metabolism. When radiolabeled ticagrelor is administered, the mean recovery of radioactivity is approximately 84% (57.8% in faeces, 26.5% in urine). Recoveries of ticagrelor and the active metabolite in urine were both less than 1% of the dose. The primary route of elimination for the active metabolite is most likely via biliary secretion. The mean t1/2 was approximately 7 hours for ticagrelor and 8.5 hours for the active metabolite.
Older peopleHigher exposures to ticagrelor (approximately 25% for both Cmax and AUC) and the active metabolite were observed in elderly (≥ 75years) ACS patients compared to younger patients by the population pharmacokinetic analysis. These differences are not considered clinically significant (see section 4.2).
PaediatricTicagrelor has not been evaluated in a paediatric population (see section 4.2 and 5.1).
GenderHigher exposures to ticagrelor and the active metabolite were observed in women compared to men. These differences are not considered clinically significant.
Renal impairmentExposure to ticagrelor was approximately 20% lower and exposure to active metabolite was approximately 17% higher in patients with severe renal impairment (creatinine clearance <30 ml/min) compared to subjects with normal renal function (see section 4.2).
Hepatic impairmentCmax and AUC for ticagrelor were 12% and 23% higher in patients with mild hepatic impairment compared to matched healthy subjects, respectively (see section 4.2). Ticagrelor has not been studied in patients with moderate or severe hepatic impairment and its use in these patients is contraindicated (see section 4.3 and 4.4).
EthnicityPatients of Asian descent have a 39% higher mean bioavailability compared to Caucasian patients. Patients self-identified as Black had an 18% lower bioavailability of ticagrelor compared to Caucasian patients. In clinical pharmacology studies, the exposure (Cmax and AUC) to ticagrelor in Japanese subjects was approximately 40% (20% after adjusting for body weight) higher compared to that in Caucasians.
