no precautions are necessary with concomitant administration with xarelto as the change in exposure is unlikely to affect the bleeding risk [see clinical pharmacology (12.3) ] . interaction with combined p-gp and moderate cyp3a inhibitors in patients with renal impairment xarelto should not be used in patients with crcl 15 to <80 ml/min who are receiving concomitant combined p-gp and moderate cyp3a inhibitors (e.g., erythromycin) unless the potential benefit justifies the potential risk [see warnings and precautions (5.4) and clinical pharmacology (12.3) ] . 7.3 drugs that induce cytochrome p450 3a enzymes and drug transport systems avoid concomitant use of xarelto with drugs that are combined p-gp and strong cyp3a inducers (e.g., carbamazepine, phenytoin, rifampin, st. john's wort) [see warnings and precautions (5.6) and clinical pharmacology (12.3) ] . 7.4 anticoagulants and nsaids/aspirin coadministration of enoxaparin, warfarin, aspirin, clopidogrel and chronic nsaid use may increase the risk of bleeding [see clinical pharmacology (12.3) ]. avoid concurrent use of xarelto with other anticoagulants due to increased bleeding risk unless benefit outweighs risk. promptly evaluate any signs or symptoms of blood loss if patients are treated concomitantly with aspirin, other platelet aggregation inhibitors, or nsaids [see warnings and precautions (5.2) ] .

ce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. there are limited data on the relative effectiveness of xarelto and warfarin in reducing the risk of stroke and systemic embolism when warfarin therapy is well-controlled [see clinical studies (14.1) ]. 1.2 treatment of deep vein thrombosis xarelto is indicated for the treatment of deep vein thrombosis (dvt). 1.3 treatment of pulmonary embolism xarelto is indicated for the treatment of pulmonary embolism (pe). 1.4 reduction in the risk of recurrence of deep vein thrombosis and/or pulmonary embolism xarelto is indicated for the reduction in the risk of recurrence of dvt and/or pe in patients at continued risk for recurrent dvt and/or pe after completion of initial treatment lasting at least 6 months. 1.5 prophylaxis of deep vein thrombosis following hip or knee replacement surgery xarelto is indicated for the prophylaxis of dvt, which may lead to pe in patients undergoing knee or hip replacement surgery. 1.6 prophylaxis of venous thromboembolism in acutely ill medical patients at risk for thromboembolic complications not at high risk of bleeding xarelto is indicated for the prophylaxis of venous thromboembolism (vte) and vte related death during hospitalization and post hospital discharge in adult patients admitted for an acute medical illness who are at risk for thromboembolic complications due to moderate or severe restricted mobility and other risk factors for vte and not at high risk of bleeding [see warnings and precautions (5.2) and clinical studies (14.5) ] . 1.7 reduction of risk of major cardiovascular events in patients with coronary artery disease (cad) xarelto, in combination with aspirin, is indicated to reduce the risk of major cardiovascular events (cardiovascular death, myocardial infarction, and stroke) in patients with coronary artery disease. 1.8 reduction of risk of major thrombotic vascular events in patients with peripheral artery disease (pad), including patients after lower extremity revascularization due to symptomatic pad xarelto, in combination with aspirin, is indicated to reduce the risk of major thrombotic vascular events (myocardial infarction, ischemic stroke, acute limb ischemia, and major amputation of a vascular etiology) in patients with pad, including patients who have recently undergone a lower extremity revascularization procedure due to symptomatic pad.

on of a course of therapy, consider coverage with another anticoagulant [see dosage and administration (2.2 , 2.3) and clinical studies (14.1) ] . 5.2 risk of bleeding xarelto increases the risk of bleeding and can cause serious or fatal bleeding. in deciding whether to prescribe xarelto to patients at increased risk of bleeding, the risk of thrombotic events should be weighed against the risk of bleeding. promptly evaluate any signs or symptoms of blood loss and consider the need for blood replacement. discontinue xarelto in patients with active pathological hemorrhage. the terminal elimination half-life of rivaroxaban is 5 to 9 hours in healthy subjects aged 20 to 45 years. concomitant use of other drugs that impair hemostasis increases the risk of bleeding. these include aspirin, p2y 12 platelet inhibitors, dual antiplatelet therapy, other antithrombotic agents, fibrinolytic therapy, non-steroidal anti-inflammatory drugs (nsaids) [see drug interactions (7.4) ] , selective serotonin reuptake inhibitors, and serotonin norepinephrine reuptake inhibitors. concomitant use of drugs that are known combined p-gp and strong cyp3a inhibitors increases rivaroxaban exposure and may increase bleeding risk [see drug interactions (7.2) ] . risk of hemorrhage in acutely ill medical patients at high risk of bleeding acutely ill medical patients with the following conditions are at increased risk of bleeding with the use of xarelto for primary vte prophylaxis: history of bronchiectasis, pulmonary cavitation, or pulmonary hemorrhage, active cancer (i.e. undergoing acute, in-hospital cancer treatment), active gastroduodenal ulcer in the three months prior to treatment, history of bleeding in the three months prior to treatment, or dual antiplatelet therapy. xarelto is not for use for primary vte prophylaxis in these hospitalized, acutely ill medical patients at high risk of bleeding. reversal of anticoagulant effect an agent to reverse the anti-factor xa activity of rivaroxaban is available. because of high plasma protein binding, rivaroxaban is not dialyzable [see clinical pharmacology (12.3) ] . protamine sulfate and vitamin k are not expected to affect the anticoagulant activity of rivaroxaban. use of procoagulant reversal agents, such as prothrombin complex concentrate (pcc), activated prothrombin complex concentrate or recombinant factor viia, may be considered but has not been evaluated in clinical efficacy and safety studies. monitoring for the anticoagulation effect of rivaroxaban using a clotting test (pt, inr or aptt) or anti-factor xa (fxa) activity is not recommended. 5.3 spinal/epidural anesthesia or puncture when neuraxial anesthesia (spinal/epidural anesthesia) or spinal puncture is employed, patients treated with anticoagulant agents for prevention of thromboembolic complications are at risk of developing an epidural or spinal hematoma which can result in long-term or permanent paralysis [see boxed warning ] . to reduce the potential risk of bleeding associated with the concurrent use of xarelto and epidural or spinal anesthesia/analgesia or spinal puncture, consider the pharmacokinetic profile of xarelto [see clinical pharmacology (12.3) ] . placement or removal of an epidural catheter or lumbar puncture is best performed when the anticoagulant effect of xarelto is low; however, the exact timing to reach a sufficiently low anticoagulant effect in each patient is not known. an indwelling epidural or intrathecal catheter should not be removed before at least 2 half-lives have elapsed (i.e., 18 hours in young patients aged 20 to 45 years and 26 hours in elderly patients aged 60 to 76 years), after the last administration of xarelto [see clinical pharmacology (12.3) ] . the next xarelto dose should not be administered earlier than 6 hours after the removal of the catheter. if traumatic puncture occurs, delay the administration of xarelto for 24 hours. should the physician decide to administer anticoagulation in the context of epidural or spinal anesthesia/analgesia or lumbar puncture, monitor frequently to detect any signs or symptoms of neurological impairment, such as midline back pain, sensory and motor deficits (numbness, tingling, or weakness in lower limbs), bowel and/or bladder dysfunction. instruct patients to immediately report if they experience any of the above signs or symptoms. if signs or symptoms of spinal hematoma are suspected, initiate urgent diagnosis and treatment including consideration for spinal cord decompression even though such treatment may not prevent or reverse neurological sequelae. 5.4 use in patients with renal impairment nonvalvular atrial fibrillation periodically assess renal function as clinically indicated (i.e., more frequently in situations in which renal function may decline) and adjust therapy accordingly [see dosage and administration (2.1) ] . consider dose adjustment or discontinuation of xarelto in patients who develop acute renal failure while on xarelto [see use in specific populations (8.6) ]. treatment of deep vein thrombosis (dvt), pulmonary embolism (pe), and reduction in the risk of recurrence of dvt and of pe in patients with crcl <30 ml/min, rivaroxaban exposure and pharmacodynamic effects are increased compared to patients with normal renal function. there are limited clinical data in patients with crcl 15 to <30 ml/min; therefore, observe closely and promptly evaluate any signs or symptoms of blood loss in these patients. there are no clinical data in patients with crcl <15 ml/min (including patients on dialysis); therefore, avoid the use of xarelto in these patients. discontinue xarelto in patients who develop acute renal failure while on treatment [see use in specific populations (8.6) ] . prophylaxis of deep vein thrombosis following hip or knee replacement surgery in patients with crcl <30 ml/min, rivaroxaban exposure and pharmacodynamic effects are increased compared to patients with normal renal function. there are limited clinical data in patients with crcl 15 to <30 ml/min; therefore, observe closely and promptly evaluate any signs or symptoms of blood loss in these patients. there are no clinical data in patients with crcl <15 ml/min (including patients on dialysis); therefore, avoid the use of xarelto in these patients. discontinue xarelto in patients who develop acute renal failure while on treatment [see use in specific populations (8.6) ]. prophylaxis of venous thromboembolism in acutely ill medical patients at risk for thromboembolic complications not at high risk of bleeding in patients with crcl <30 ml/min, rivaroxaban exposure and pharmacodynamic effects are increased compared to patients with normal renal function. there are limited clinical data in patients with crcl 15 to <30 ml/min; therefore, observe closely and promptly evaluate any signs or symptoms of blood loss in these patients. there are no clinical data in patients with crcl <15 ml/min (including patients on dialysis); therefore, avoid the use of xarelto in these patients. discontinue xarelto in patients who develop acute renal failure while on treatment [see use in specific populations (8.6) ]. 5.5 use in patients with hepatic impairment no clinical data are available for patients with severe hepatic impairment. avoid use of xarelto in patients with moderate (child-pugh b) and severe (child-pugh c) hepatic impairment or with any hepatic disease associated with coagulopathy since drug exposure and bleeding risk may be increased [see use in specific populations (8.7) ] . 5.6 use with p-gp and strong cyp3a inhibitors or inducers avoid concomitant use of xarelto with known combined p-gp and strong cyp3a inhibitors [see drug interactions (7.2) ] . avoid concomitant use of xarelto with drugs that are known combined p-gp and strong cyp3a inducers [see drug interactions (7.3) ] . 5.7 risk of pregnancy-related hemorrhage in pregnant women, xarelto should be used only if the potential benefit justifies the potential risk to the mother and fetus. xarelto dosing in pregnancy has not been studied. the anticoagulant effect of xarelto cannot be monitored with standard laboratory testing. promptly evaluate any signs or symptoms suggesting blood loss (e.g., a drop in hemoglobin and/or hematocrit, hypotension, or fetal distress) [see warnings and precautions (5.2) and use in specific populations (8.1) ] . 5.8 patients with prosthetic heart valves on the basis of the galileo study, use of xarelto is not recommended in patients who have had transcatheter aortic valve replacement (tavr) because patients randomized to xarelto experienced higher rates of death and bleeding compared to those randomized to an anti-platelet regimen. the safety and efficacy of xarelto have not been studied in patients with other prosthetic heart valves or other valve procedures. use of xarelto is not recommended in patients with prosthetic heart valves. 5.9 acute pe in hemodynamically unstable patients or patients who require thrombolysis or pulmonary embolectomy initiation of xarelto is not recommended acutely as an alternative to unfractionated heparin in patients with pulmonary embolism who present with hemodynamic instability or who may receive thrombolysis or pulmonary embolectomy. 5.10 increased risk of thrombosis in patients with triple positive antiphospholipid syndrome direct-acting oral anticoagulants (doacs), including xarelto, are not recommended for use in patients with triple-positive antiphospholipid syndrome (aps). for patients with aps (especially those who are triple positive [positive for lupus anticoagulant, anticardiolipin, and anti-beta 2-glycoprotein i antibodies]), treatment with doacs has been associated with increased rates of recurrent thrombotic events compared with vitamin k antagonist therapy.

when switching patients from warfarin to xarelto, discontinue warfarin and start xarelto as soon as the international normalized ratio (inr) is below 3.0 to avoid periods of inadequate anticoagulation. switching from xarelto to warfarin - no clinical trial data are available to guide converting patients from xarelto to warfarin. xarelto affects inr, so inr measurements made during coadministration with warfarin may not be useful for determining the appropriate dose of warfarin. one approach is to discontinue xarelto and begin both a parenteral anticoagulant and warfarin at the time the next dose of xarelto would have been taken. switching from xarelto to anticoagulants other than warfarin - for patients currently taking xarelto and transitioning to an anticoagulant with rapid onset, discontinue xarelto and give the first dose of the other anticoagulant (oral or parenteral) at the time that the next xarelto dose would have been taken [see drug interactions (7.4) ] . switching from anticoagulants other than warfarin to xarelto - for patients currently receiving an anticoagulant other than warfarin, start xarelto 0 to 2 hours prior to the next scheduled evening administration of the drug (e.g., low molecular weight heparin or non-warfarin oral anticoagulant) and omit administration of the other anticoagulant. for unfractionated heparin being administered by continuous infusion, stop the infusion and start xarelto at the same time. 2.3 discontinuation for surgery and other interventions if anticoagulation must be discontinued to reduce the risk of bleeding with surgical or other procedures, xarelto should be stopped at least 24 hours before the procedure to reduce the risk of bleeding [see warnings and precautions (5.2) ] . in deciding whether a procedure should be delayed until 24 hours after the last dose of xarelto, the increased risk of bleeding should be weighed against the urgency of intervention. xarelto should be restarted after the surgical or other procedures as soon as adequate hemostasis has been established, noting that the time to onset of therapeutic effect is short [see warnings and precautions (5.1) ] . if oral medication cannot be taken during or after surgical intervention, consider administering a parenteral anticoagulant. 2.4 missed dose • for patients receiving 2.5 mg twice daily: if a dose is missed, the patient should take a single 2.5 mg xarelto dose as recommended at the next scheduled time. • for patients receiving 15 mg twice daily: the patient should take xarelto immediately to ensure intake of 30 mg xarelto per day. two 15 mg tablets may be taken at once. • for patients receiving 20 mg, 15 mg or 10 mg once daily: the patient should take the missed xarelto dose immediately. the dose should not be doubled within the same day to make up for a missed dose. 2.5 administration options for patients who are unable to swallow whole tablets, xarelto tablets (all strengths) may be crushed and mixed with applesauce immediately prior to use and administered orally. after the administration of a crushed xarelto 15 mg or 20 mg tablet, the dose should be immediately followed by food. administration with food is not required for the 2.5 mg or 10 mg tablets [see clinical pharmacology (12.3) ] . administration via nasogastric (ng) tube or gastric feeding tube: after confirming gastric placement of the tube, xarelto tablets (all strengths) may be crushed and suspended in 50 ml of water and administered via an ng tube or gastric feeding tube. since rivaroxaban absorption is dependent on the site of drug release, avoid administration of xarelto distal to the stomach which can result in reduced absorption and thereby, reduced drug exposure. after the administration of a crushed xarelto 15 mg or 20 mg tablet, the dose should then be immediately followed by enteral feeding. enteral feeding is not required following administration of the 2.5 mg or 10 mg tablets [see clinical pharmacology (12.3) ] . crushed xarelto tablets (all strengths) are stable in water and in applesauce for up to 4 hours. an in vitro compatibility study indicated that there is no adsorption of rivaroxaban from a water suspension of a crushed xarelto tablet to pvc or silicone nasogastric (ng) tubing.

no precautions are necessary with concomitant administration with xarelto as the change in exposure is unlikely to affect the bleeding risk [see clinical pharmacology (12.3) ] . interaction with combined p-gp and moderate cyp3a inhibitors in patients with renal impairment xarelto should not be used in patients with crcl 15 to <80 ml/min who are receiving concomitant combined p-gp and moderate cyp3a inhibitors (e.g., erythromycin) unless the potential benefit justifies the potential risk [see warnings and precautions (5.4) and clinical pharmacology (12.3) ] . 7.3 drugs that induce cytochrome p450 3a enzymes and drug transport systems avoid concomitant use of xarelto with drugs that are combined p-gp and strong cyp3a inducers (e.g., carbamazepine, phenytoin, rifampin, st. john's wort) [see warnings and precautions (5.6) and clinical pharmacology (12.3) ] . 7.4 anticoagulants and nsaids/aspirin coadministration of enoxaparin, warfarin, aspirin, clopidogrel and chronic nsaid use may increase the risk of bleeding [see clinical pharmacology (12.3) ]. avoid concurrent use of xarelto with other anticoagulants due to increased bleeding risk unless benefit outweighs risk. promptly evaluate any signs or symptoms of blood loss if patients are treated concomitantly with aspirin, other platelet aggregation inhibitors, or nsaids [see warnings and precautions (5.2) ] .

unknown. in the u.s. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. clinical considerations disease-associated maternal and/or embryo/fetal risk pregnancy is a risk factor for venous thromboembolism and that risk is increased in women with inherited or acquired thrombophilias. pregnant women with thromboembolic disease have an increased risk of maternal complications including pre-eclampsia. maternal thromboembolic disease increases the risk for intrauterine growth restriction, placental abruption and early and late pregnancy loss. fetal/neonatal adverse reactions based on the pharmacologic activity of factor xa inhibitors and the potential to cross the placenta, bleeding may occur at any site in the fetus and/or neonate. labor or delivery all patients receiving anticoagulants, including pregnant women, are at risk for bleeding and this risk may be increased during labor or delivery [see warnings and precautions (5.7) ]. the risk of bleeding should be balanced with the risk of thrombotic events when considering the use of xarelto in this setting. data human data there are no adequate or well-controlled studies of xarelto in pregnant women, and dosing for pregnant women has not been established. post-marketing experience is currently insufficient to determine a rivaroxaban-associated risk for major birth defects or miscarriage. in an in vitro placenta perfusion model, unbound rivaroxaban was rapidly transferred across the human placenta. animal data rivaroxaban crosses the placenta in animals. rivaroxaban increased fetal toxicity (increased resorptions, decreased number of live fetuses, and decreased fetal body weight) when pregnant rabbits were given oral doses of ≥10 mg/kg rivaroxaban during the period of organogenesis. this dose corresponds to about 4 times the human exposure of unbound drug, based on auc comparisons at the highest recommended human dose of 20 mg/day. fetal body weights decreased when pregnant rats were given oral doses of 120 mg/kg during the period of organogenesis. this dose corresponds to about 14 times the human exposure of unbound drug. in rats, peripartal maternal bleeding and maternal and fetal death occurred at the rivaroxaban dose of 40 mg/kg (about 6 times maximum human exposure of the unbound drug at the human dose of 20 mg/day). 8.2 lactation risk summary rivaroxaban has been detected in human milk. there are insufficient data to determine the effects of rivaroxaban on the breastfed child or on milk production. rivaroxaban and/or its metabolites were present in the milk of rats. the developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for xarelto and any potential adverse effects on the breastfed infant from xarelto or from the underlying maternal condition (see data ) . data animal data following a single oral administration of 3 mg/kg of radioactive [ 14 c]-rivaroxaban to lactating rats between day 8 to 10 postpartum, the concentration of total radioactivity was determined in milk samples collected up to 32 hours post-dose. the estimated amount of radioactivity excreted with milk within 32 hours after administration was 2.1% of the maternal dose. 8.3 females and males of reproductive potential females of reproductive potential requiring anticoagulation should discuss pregnancy planning with their physician. the risk of clinically significant uterine bleeding, potentially requiring gynecological surgical interventions, identified with oral anticoagulants including xarelto should be assessed in females of reproductive potential and those with abnormal uterine bleeding. 8.4 pediatric use safety and effectiveness in pediatric patients have not been established. 8.5 geriatric use of the total number of adult patients in clinical trials for the approved indications of xarelto (n=64,943 patients), 64 percent were 65 years and over, with 27 percent 75 years and over. in clinical trials the efficacy of xarelto in the elderly (65 years or older) was similar to that seen in patients younger than 65 years. both thrombotic and bleeding event rates were higher in these older patients [see clinical pharmacology (12.3) and clinical studies (14) ] . 8.6 renal impairment in pharmacokinetic studies, compared to healthy subjects with normal creatinine clearance, rivaroxaban exposure increased by approximately 44 to 64% in subjects with renal impairment. increases in pharmacodynamic effects were also observed [see clinical pharmacology (12.3) ] . nonvalvular atrial fibrillation patients with chronic kidney disease not on dialysis in the rocket af trial, patients with crcl 30 to 50 ml/min were administered xarelto 15 mg once daily resulting in serum concentrations of rivaroxaban and clinical outcomes similar to those in patients with better renal function administered xarelto 20 mg once daily. patients with crcl <30 ml/min were not studied, but administration of xarelto 15 mg once daily is expected to result in serum concentrations of rivaroxaban similar to those in patients with moderate renal impairment [see clinical pharmacology (12.3) ] . patients with end-stage renal disease on dialysis clinical efficacy and safety studies with xarelto did not enroll patients with end-stage renal disease (esrd) on dialysis. in patients with esrd maintained on intermittent hemodialysis, administration of xarelto 15 mg once daily will result in concentrations of rivaroxaban and pharmacodynamic activity similar to those observed in the rocket af study [see clinical pharmacology (12.2 , 12.3) ] . it is not known whether these concentrations will lead to similar stroke reduction and bleeding risk in patients with esrd on dialysis as was seen in rocket af. treatment of dvt and/or pe and reduction in the risk of recurrence of dvt and/or pe in the einstein trials, patients with crcl values <30 ml/min at screening were excluded from the studies, but administration of xarelto is expected to result in serum concentrations of rivaroxaban similar to those in patients with moderate renal impairment (crcl 30 to <50 ml/min) [see clinical pharmacology (12.3) ]. observe closely and promptly evaluate any signs or symptoms of blood loss in patients with crcl 15 to <30 ml/min. avoid the use of xarelto in patients with crcl <15 ml/min. prophylaxis of dvt following hip or knee replacement surgery the combined analysis of the record 1–3 clinical efficacy studies did not show an increase in bleeding risk for patients with crcl 30 to 50 ml/min and reported a possible increase in total venous thromboemboli in this population. in the record 1–3 trials, patients with crcl values <30 ml/min at screening were excluded from the studies, but administration of xarelto 10 mg once daily is expected to result in serum concentrations of rivaroxaban similar to those in patients with moderate renal impairment (crcl 30 to <50 ml/min) [see clinical pharmacology (12.3) ]. observe closely and promptly evaluate any signs or symptoms of blood loss in patients with crcl 15 to <30 ml/min. avoid the use of xarelto in patients with crcl <15 ml/min. prophylaxis of venous thromboembolism in acutely ill medical patients at risk for thromboembolic complications not at high risk of bleeding patients with crcl values <30 ml/min at screening were excluded from the magellan study. in patients with crcl <30 ml/min a dose of xarelto 10 mg once daily is expected to result in serum concentrations of rivaroxaban similar to those in patients with moderate renal impairment (crcl 30 to <50 ml/min) [see clinical pharmacology (12.3) ] . observe closely and promptly evaluate any signs or symptoms of blood loss in patients with crcl 15 to <30 ml/min. avoid use of xarelto in patients with crcl <15 ml/min. reduction of risk of major cardiovascular events in patients with cad and reduction of risk of major thrombotic vascular events in patients with pad, including patients after recent lower extremity revascularization due to symptomatic pad patients with chronic kidney disease not on dialysis patients with a crcl <15 ml/min at screening were excluded from compass and voyager, and limited data are available for patients with a crcl of 15 to 30 ml/min. in patients with crcl <30 ml/min, a dose of 2.5 mg xarelto twice daily is expected to give an exposure similar to that in patients with moderate renal impairment (crcl 30 to <50 ml/min) [see clinical pharmacology (12.3) ] , whose efficacy and safety outcomes were similar to those with preserved renal function. patients with end-stage renal disease on dialysis no clinical outcome data is available for the use of xarelto with aspirin in patients with esrd on dialysis since these patients were not enrolled in compass or voyager. in patients with esrd maintained on intermittent hemodialysis, administration of xarelto 2.5 mg twice daily will result in concentrations of rivaroxaban and pharmacodynamic activity similar to those observed in moderate renal impaired patients in the compass study [see clinical pharmacology (12.2 , 12.3) ] . it is not known whether these concentrations will lead to similar cv risk reduction and bleeding risk in patients with esrd on dialysis as was seen in compass. 8.7 hepatic impairment in a pharmacokinetic study, compared to healthy subjects with normal liver function, auc increases of 127% were observed in subjects with moderate hepatic impairment (child-pugh b). the safety or pk of xarelto in patients with severe hepatic impairment (child-pugh c) has not been evaluated [see clinical pharmacology (12.3) ] . avoid the use of xarelto in patients with moderate (child-pugh b) and severe (child-pugh c) hepatic impairment or with any hepatic disease associated with coagulopathy.

ease-associated maternal and/or embryo/fetal risk pregnancy is a risk factor for venous thromboembolism and that risk is increased in women with inherited or acquired thrombophilias. pregnant women with thromboembolic disease have an increased risk of maternal complications including pre-eclampsia. maternal thromboembolic disease increases the risk for intrauterine growth restriction, placental abruption and early and late pregnancy loss. fetal/neonatal adverse reactions based on the pharmacologic activity of factor xa inhibitors and the potential to cross the placenta, bleeding may occur at any site in the fetus and/or neonate. labor or delivery all patients receiving anticoagulants, including pregnant women, are at risk for bleeding and this risk may be increased during labor or delivery [see warnings and precautions (5.7) ]. the risk of bleeding should be balanced with the risk of thrombotic events when considering the use of xarelto in this setting. data human data there are no adequate or well-controlled studies of xarelto in pregnant women, and dosing for pregnant women has not been established. post-marketing experience is currently insufficient to determine a rivaroxaban-associated risk for major birth defects or miscarriage. in an in vitro placenta perfusion model, unbound rivaroxaban was rapidly transferred across the human placenta. animal data rivaroxaban crosses the placenta in animals. rivaroxaban increased fetal toxicity (increased resorptions, decreased number of live fetuses, and decreased fetal body weight) when pregnant rabbits were given oral doses of ≥10 mg/kg rivaroxaban during the period of organogenesis. this dose corresponds to about 4 times the human exposure of unbound drug, based on auc comparisons at the highest recommended human dose of 20 mg/day. fetal body weights decreased when pregnant rats were given oral doses of 120 mg/kg during the period of organogenesis. this dose corresponds to about 14 times the human exposure of unbound drug. in rats, peripartal maternal bleeding and maternal and fetal death occurred at the rivaroxaban dose of 40 mg/kg (about 6 times maximum human exposure of the unbound drug at the human dose of 20 mg/day).

measures in subjects with renal impairment relative to healthy subjects from clinical pharmacology studies measure parameter creatinine clearance (ml/min) 50–79 30–49 15–29 esrd (on dialysis) separate stand-alone study. esrd (post-dialysis) pt = prothrombin time; fxa = coagulation factor xa; auc = area under the plasma concentration-time curve; auec = area under the effect-time curve exposure auc

hepatic impairment (child-pugh a class). there is no clear understanding of the impact of hepatic impairment beyond this degree on the coagulation cascade and its relationship to efficacy and safety. 12.3 pharmacokinetics absorption the absolute bioavailability of rivaroxaban is dose-dependent. for the 2.5 mg and 10 mg dose, it is estimated to be 80% to 100% and is not affected by food. xarelto 2.5 mg and 10 mg tablets can be taken with or without food. for the 20 mg dose in the fasted state, the absolute bioavailability is approximately 66%. coadministration of xarelto with food increases the bioavailability of the 20 mg dose (mean auc and c max increasing by 39% and 76% respectively with food). xarelto 15 mg and 20 mg tablets should be taken with food [see dosage and administration (2.1) ] . the maximum concentrations (c max ) of rivaroxaban appear 2 to 4 hours after tablet intake. the pharmacokinetics of rivaroxaban were not affected by drugs altering gastric ph. coadministration of xarelto (30 mg single dose) with the h 2 -receptor antagonist ranitidine (150 mg twice daily), the antacid aluminum hydroxide/magnesium hydroxide (10 ml) or xarelto (20 mg single dose) with the ppi omeprazole (40 mg once daily) did not show an effect on the bioavailability and exposure of rivaroxaban (see figure 3 ). absorption of rivaroxaban is dependent on the site of drug release in the gi tract. a 29% and 56% decrease in auc and c max compared to tablet was reported when rivaroxaban granulate is released in the proximal small intestine. exposure is further reduced when drug is released in the distal small intestine, or ascending colon. avoid administration of rivaroxaban distal to the stomach which can result in reduced absorption and related drug exposure. in a study with 44 healthy subjects, both mean auc and c max values for 20 mg rivaroxaban administered orally as a crushed tablet mixed in applesauce were comparable to that after the whole tablet. however, for the crushed tablet suspended in water and administered via an ng tube followed by a liquid meal, only mean auc was comparable to that after the whole tablet, and c max was 18% lower. distribution plasma protein binding of rivaroxaban in human plasma is approximately 92% to 95%, with albumin being the main binding component. the steady-state volume of distribution in healthy subjects is approximately 50 l. metabolism approximately 51% of an orally administered [ 14 c]-rivaroxaban dose was recovered as inactive metabolites in urine (30%) and feces (21%). oxidative degradation catalyzed by cyp3a4/5 and cyp2j2 and hydrolysis are the major sites of biotransformation. unchanged rivaroxaban was the predominant moiety in plasma with no major or active circulating metabolites. excretion in a phase 1 study, following the administration of [ 14 c]-rivaroxaban, approximately one-third (36%) was recovered as unchanged drug in the urine and 7% was recovered as unchanged drug in feces. unchanged drug is excreted into urine, mainly via active tubular secretion and to a lesser extent via glomerular filtration (approximate 5:1 ratio). rivaroxaban is a substrate of the efflux transporter proteins p-gp and abcg2 (also abbreviated bcrp). rivaroxaban's affinity for influx transporter proteins is unknown. rivaroxaban is a low-clearance drug, with a systemic clearance of approximately 10 l/hr in healthy volunteers following intravenous administration. the terminal elimination half-life of rivaroxaban is 5 to 9 hours in healthy subjects aged 20 to 45 years. specific populations the effects of level of renal impairment, age, body weight, and level of hepatic impairment on the pharmacokinetics of rivaroxaban are summarized in figure 2. figure 2: effect of specific populations on the pharmacokinetics of rivaroxaban [see dosage and administration (2.1) ] gender gender did not influence the pharmacokinetics or pharmacodynamics of xarelto. race healthy japanese subjects were found to have 20 to 40% on average higher exposures compared to other ethnicities including chinese. however, these differences in exposure are reduced when values are corrected for body weight. elderly the terminal elimination half-life is 11 to 13 hours in the elderly subjects aged 60 to 76 years [see use in specific populations (8.5) ] . renal impairment the safety and pharmacokinetics of single-dose xarelto (10 mg) were evaluated in a study in healthy subjects [crcl ≥80 ml/min (n=8)] and in subjects with varying degrees of renal impairment (see figure 2 ). compared to healthy subjects with normal creatinine clearance, rivaroxaban exposure increased in subjects with renal impairment. increases in pharmacodynamic effects were also observed [see use in specific populations (8.6) ] . hemodialysis in esrd subjects: systemic exposure to rivaroxaban administered as a single 15 mg dose in esrd subjects dosed 3 hours after the completion of a 4-hour hemodialysis session (post-dialysis) is 56% higher when compared to subjects with normal renal function (see table 11 ). the systemic exposure to rivaroxaban administered 2 hours prior to a 4-hour hemodialysis session with a dialysate flow rate of 600 ml/min and a blood flow rate in the range of 320 to 400 ml/min is 47% higher compared to those with normal renal function. the extent of the increase is similar to the increase in patients with crcl 15 to 50 ml/min taking xarelto 15 mg. hemodialysis had no significant impact on rivaroxaban exposure. protein binding was similar (86% to 89%) in healthy controls and esrd subjects in this study. hepatic impairment the safety and pharmacokinetics of single-dose xarelto (10 mg) were evaluated in a study in healthy subjects (n=16) and subjects with varying degrees of hepatic impairment (see figure 2 ). no patients with severe hepatic impairment (child-pugh c) were studied. compared to healthy subjects with normal liver function, significant increases in rivaroxaban exposure were observed in subjects with moderate hepatic impairment (child-pugh b) (see figure 2 ). increases in pharmacodynamic effects were also observed [see use in specific populations (8.7) ] . figure 2 drug interactions in vitro studies indicate that rivaroxaban neither inhibits the major cytochrome p450 enzymes cyp1a2, 2c8, 2c9, 2c19, 2d6, 2j2, and 3a nor induces cyp1a2, 2b6, 2c19, or 3a. in vitro data also indicates a low rivaroxaban inhibitory potential for p-gp and abcg2 transporters. the effects of coadministered drugs on the pharmacokinetics of rivaroxaban exposure are summarized in figure 3 [see drug interactions (7) ] . figure 3: effect of coadministered drugs on the pharmacokinetics of rivaroxaban anticoagulants in a drug interaction study, single doses of enoxaparin (40 mg subcutaneous) and xarelto (10 mg) given concomitantly resulted in an additive effect on anti-factor xa activity. in another study, single doses of warfarin (15 mg) and xarelto (5 mg) resulted in an additive effect on factor xa inhibition and pt. neither enoxaparin nor warfarin affected the pharmacokinetics of rivaroxaban (see figure 3 ). nsaids/aspirin in rocket af, concomitant aspirin use (almost exclusively at a dose of 100 mg or less) during the double-blind phase was identified as an independent risk factor for major bleeding. nsaids are known to increase bleeding, and bleeding risk may be increased when nsaids are used concomitantly with xarelto. neither naproxen nor aspirin affected the pharmacokinetics of rivaroxaban (see figure 3 ). clopidogrel in two drug interaction studies where clopidogrel (300 mg loading dose followed by 75 mg daily maintenance dose) and xarelto (15 mg single dose) were coadministered in healthy subjects, an increase in bleeding time to 45 minutes was observed in approximately 45% and 30% of subjects in these studies, respectively. the change in bleeding time was approximately twice the maximum increase seen with either drug alone. there was no change in the pharmacokinetics of either drug. drug-disease interactions with drugs that inhibit cytochrome p450 3a enzymes and drug transport systems in a pharmacokinetic trial, xarelto was administered as a single dose in subjects with mild (crcl = 50 to 79 ml/min) or moderate renal impairment (crcl = 30 to 49 ml/min) receiving multiple doses of erythromycin (a combined p-gp and moderate cyp3a inhibitor). compared to xarelto administered alone in subjects with normal renal function (crcl >80 ml/min), subjects with mild and moderate renal impairment concomitantly receiving erythromycin reported a 76% and 99% increase in auc inf and a 56% and 64% increase in c max , respectively. similar trends in pharmacodynamic effects were also observed. figure 3 12.6 qt/qtc prolongation in a thorough qt study in healthy men and women aged 50 years and older, no qtc prolonging effects were observed for xarelto (15 mg and 45 mg, single-dose).

meprazole (40 mg once daily) did not show an effect on the bioavailability and exposure of rivaroxaban (see figure 3 ). absorption of rivaroxaban is dependent on the site of drug release in the gi tract. a 29% and 56% decrease in auc and c max compared to tablet was reported when rivaroxaban granulate is released in the proximal small intestine. exposure is further reduced when drug is released in the distal small intestine, or ascending colon. avoid administration of rivaroxaban distal to the stomach which can result in reduced absorption and related drug exposure. in a study with 44 healthy subjects, both mean auc and c max values for 20 mg rivaroxaban administered orally as a crushed tablet mixed in applesauce were comparable to that after the whole tablet. however, for the crushed tablet suspended in water and administered via an ng tube followed by a liquid meal, only mean auc was comparable to that after the whole tablet, and c max was 18% lower. distribution plasma

volunteers following intravenous administration. the terminal elimination half-life of rivaroxaban is 5 to 9 hours in healthy subjects aged 20 to 45 years. specific populations the effects of level of renal impairment, age, body weight, and level of hepatic impairment on the pharmacokinetics of rivaroxaban are summarized in figure 2. figure 2: effect of specific populations on the pharmacokinetics of rivaroxaban [see dosage and administration (2.1) ] gender gender did not influence the pharmacokinetics or pharmacodynamics of xarelto. race healthy japanese subjects were found to have 20 to 40%

elimination half-life is 11 to 13 hours in the elderly subjects aged 60 to 76 years [see use in specific populations (8.5) ] . renal impairment the safety and pharmacokinetics of single-dose xarelto (10 mg) were evaluated in a study in healthy subjects [crcl ≥80 ml/min (n=8)] and in subjects with varying degrees of renal impairment (see figure 2 ). compared to healthy subjects with normal creatinine clearance, rivaroxaban exposure increased in subjects with renal impairment. increases in pharmacodynamic effects were also observed [see use in specific populations (8.6) ] . hemodialysis in esrd subjects: systemic exposure to rivaroxaban administered as a single 15 mg dose in esrd subjects dosed 3 hours after the completion of a 4-hour hemodialysis session (post-dialysis) is 56% higher when compared to subjects with normal renal function (see table 11 ). the systemic exposure to rivaroxaban administered 2 hours prior to a 4-hour hemodialysis session with a dialysate flow rate of 600 ml/min and a blood flow rate in the range of 320 to 400 ml/min is 47% higher compared to those with normal renal function. the extent of the increase is similar to the increase in patients with crcl 15 to 50 ml/min taking xarelto 15 mg. hemodialysis had no significant impact on rivaroxaban exposure. protein binding was similar (86% to 89%) in healthy controls and esrd subjects in this study. hepatic impairment the safety and pharmacokinetics of single-dose xarelto (10 mg) were evaluated in a study in healthy subjects (n=16) and subjects with varying degrees of hepatic impairment (see figure 2 ). no patients with severe hepatic impairment (child-pugh c) were studied. compared to healthy subjects with normal liver function, significant increases in rivaroxaban exposure were observed in subjects with moderate hepatic impairment (child-pugh b) (see figure 2 ). increases in pharmacodynamic effects were also observed [see use in specific populations (8.7) ] . figure 2 drug interactions in vitro studies indicate that rivaroxaban neither inhibits the major cytochrome p450 enzymes cyp1a2, 2c8, 2c9, 2c19, 2d6, 2j2, and 3a nor induces cyp1a2, 2b6, 2c19, or 3a. in vitro data also indicates a low rivaroxaban inhibitory potential for p-gp and abcg2 transporters. the effects of coadministered drugs on the pharmacokinetics of rivaroxaban exposure are summarized in figure 3 [see drug interactions (7) ] . figure 3: effect of coadministered drugs on the pharmacokinetics of rivaroxaban anticoagulants in a drug interaction study, single doses of enoxaparin (40 mg subcutaneous) and xarelto (10 mg) given concomitantly resulted in an additive effect on anti-factor xa activity. in another study, single doses of warfarin (15 mg) and xarelto (5 mg) resulted in an additive effect on factor xa inhibition and pt. neither enoxaparin nor warfarin affected the pharmacokinetics of rivaroxaban (see figure 3 ). nsaids/aspirin in rocket af, concomitant aspirin use (almost exclusively at a dose of 100 mg or less) during the double-blind phase was identified as an independent risk factor for major bleeding. nsaids are known to increase bleeding, and bleeding risk may be increased when nsaids are used concomitantly with xarelto. neither naproxen nor aspirin affected the pharmacokinetics of rivaroxaban (see figure 3 ). clopidogrel in two drug interaction studies where clopidogrel (300 mg loading dose followed by 75 mg daily maintenance dose) and xarelto (15 mg single dose) were coadministered in healthy subjects, an increase in bleeding time to 45 minutes was observed in approximately 45% and 30% of subjects in these studies, respectively. the change in bleeding time was approximately twice the maximum increase seen with either drug alone. there was no change in the pharmacokinetics of either drug. drug-disease interactions with drugs that inhibit cytochrome p450 3a enzymes and drug transport systems in a pharmacokinetic trial, xarelto was administered as a single dose in subjects with mild (crcl = 50 to 79 ml/min) or moderate renal impairment (crcl = 30 to 49 ml/min) receiving multiple doses of erythromycin (a combined p-gp and moderate cyp3a inhibitor). compared to xarelto administered alone in subjects with normal renal function (crcl >80 ml/min), subjects with mild and moderate renal impairment concomitantly receiving erythromycin reported a 76% and 99% increase in auc inf and a 56% and 64% increase in c max , respectively. similar trends in pharmacodynamic effects were also observed. figure 3

� age ≥75 years, • hypertension, • heart failure or left ventricular ejection fraction ≤35%, or • diabetes mellitus rocket af was a non-inferiority study designed to demonstrate that xarelto preserved more than 50% of warfarin's effect on stroke and non-cns systemic embolism as established by previous placebo-controlled studies of warfarin in atrial fibrillation. a total of 14264 patients were randomized and followed on study treatment for a median of 590 days. the mean age was 71 years and the mean chads 2 score was 3.5. the population was 60% male, 83% caucasian, 13% asian and 1.3% black. there was a history of stroke, tia, or non-cns systemic embolism in 55% of patients, and 38% of patients had not taken a vitamin k antagonist (vka) within 6 weeks at time of screening. concomitant diseases of patients in this study included hypertension 91%, diabetes 40%, congestive heart failure 63%, and prior myocardial infarction 17%. at baseline, 37% of patients were on aspirin (almost exclusively at a dose of 100 mg or less) and few patients were on clopidogrel. patients were enrolled in eastern europe (39%); north america (19%); asia, australia, and new zealand (15%); western europe (15%); and latin america (13%). patients randomized to warfarin had a mean percentage of time in the inr target range of 2.0 to 3.0 of 55%, lower during the first few months of the study. in rocket af, xarelto was demonstrated non-inferior to warfarin for the primary composite endpoint of time to first occurrence of stroke (any type) or non-cns systemic embolism [hr (95% ci): 0.88 (0.74, 1.03)], but superiority to warfarin was not demonstrated. there is insufficient experience to determine how xarelto and warfarin compare when warfarin therapy is well-controlled. table 12 displays the overall results for the primary composite endpoint and its components. table 12: primary composite endpoint results in rocket af study (intent-to-treat population) xarelto warfarin xarelto vs. warfarin event n=7081 n (%) event rate (per 100 pt-yrs) n=7090 n (%) event rate (per 100 pt-yrs) hazard ratio (95% ci) primary composite endpoint the primary endpoint was the time to first occurrence of stroke (any type) or non-cns systemic embolism. data are shown for all randomized patients followed to site notification that the study would end. 269 (3.8) 2.1 306 (4.3) 2.4 0.88 (0.74, 1.03) stroke 253 (3.6) 2.0 281 (4.0) 2.2 hemorrhagic stroke defined as primary hemorrhagic strokes confirmed by adjudication in all randomized patients followed up to site notification 33 (0.5) 0.3 57 (0.8) 0.4 ischemic stroke 206 (2.9) 1.6 208 (2.9) 1.6 unknown stroke type 19 (0.3) 0.2 18 (0.3) 0.1 non-cns systemic embolism 20 (0.3) 0.2 27 (0.4) 0.2 figure 4 is a plot of the time from randomization to the occurrence of the first primary endpoint event in the two treatment arms. figure 4: time to first occurrence of stroke (any type) or non-cns systemic embolism by treatment group (intent-to-treat population) figure 5 shows the risk of stroke or non-cns systemic embolism across major subgroups. note: the figure above presents effects in various subgroups all of which are baseline characteristics and all of which were pre-specified (diabetic status was not pre-specified in the subgroup, but was a criterion for the chads2 score). the 95% confidence limits that are shown do not take into account how many comparisons were made, nor do they reflect the effect of a particular factor after adjustment for all other factors. apparent homogeneity or heterogeneity among groups should not be over-interpreted. figure 5: risk of stroke or non-cns systemic embolism by baseline characteristics in rocket af data are shown for all randomized patients followed to site notification that the study would end. (intent-to-treat population) the efficacy of xarelto was generally consistent across major subgroups. the protocol for rocket af did not stipulate anticoagulation after study drug discontinuation, but warfarin patients who completed the study were generally maintained on warfarin. xarelto patients were generally switched to warfarin without a period of coadministration of warfarin and xarelto, so that they were not adequately anticoagulated after stopping xarelto until attaining a therapeutic inr. during the 28 days following the end of the study, there were 22 strokes in the 4637 patients taking xarelto vs. 6 in the 4691 patients taking warfarin. few patients in rocket af underwent electrical cardioversion for atrial fibrillation. the utility of xarelto for preventing post-cardioversion stroke and systemic embolism is unknown. figure 4 figure 5 14.2 treatment of deep vein thrombosis (dvt) and/or pulmonary embolism (pe) einstein deep vein thrombosis and einstein pulmonary embolism studies xarelto for the treatment of dvt and/or pe was studied in einstein dvt [nct00440193] and einstein pe [nct00439777], multi-national, open-label, non-inferiority studies comparing xarelto (at an initial dose of 15 mg twice daily with food for the first three weeks, followed by xarelto 20 mg once daily with food) to enoxaparin 1 mg/kg twice daily for at least five days with vka and then continued with vka only after the target inr (2.0–3.0) was reached. patients who required thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent and patients with creatinine clearance <30 ml/min, significant liver disease, or active bleeding were excluded from the studies. the intended treatment duration was 3, 6, or 12 months based on investigator's assessment prior to randomization. a total of 8281 (3449 in einstein dvt and 4832 in einstein pe) patients were randomized and followed on study treatment for a mean of 208 days in the xarelto group and 204 days in the enoxaparin/vka group. the mean age was approximately 57 years. the population was 55% male, 70% caucasian, 9% asian and about 3% black. about 73% and 92% of xarelto-treated patients in the einstein dvt and einstein pe studies, respectively, received initial parenteral anticoagulant treatment for a median duration of 2 days. enoxaparin/vka-treated patients in the einstein dvt and einstein pe studies received initial parenteral anticoagulant treatment for a median duration of 8 days. aspirin was taken as on treatment concomitant antithrombotic medication by approximately 12% of patients in both treatment groups. patients randomized to vka had an unadjusted mean percentage of time in the inr target range of 2.0 to 3.0 of 58% in einstein dvt study and 60% in einstein pe study, with the lower values occurring during the first month of the study. in the einstein dvt and einstein pe studies, 49% of patients had an idiopathic dvt/pe at baseline. other risk factors included previous episode of dvt/pe (19%), recent surgery or trauma (18%), immobilization (16%), use of estrogen-containing drug (8%), known thrombophilic conditions (6%), or active cancer (5%). in the einstein dvt and einstein pe studies, xarelto was demonstrated to be non-inferior to enoxaparin/vka for the primary composite endpoint of time to first occurrence of recurrent dvt or non-fatal or fatal pe [einstein dvt hr (95% ci): 0.68 (0.44, 1.04); einstein pe hr (95% ci): 1.12 (0.75, 1.68)]. in each study the conclusion of non-inferiority was based on the upper limit of the 95% confidence interval for the hazard ratio being less than 2.0. table 13 displays the overall results for the primary composite endpoint and its components for einstein dvt and einstein pe studies. table

recurrence of dvt and/or pe einstein choice study xarelto for reduction in the risk of recurrence of dvt and of pe was evaluated in the einstein choice study [nct02064439], a multi-national, double-blind, superiority study comparing xarelto (10 or 20 mg once daily with food) to 100 mg acetylsalicylic acid (aspirin) once daily in patients who had completed 6 to 12 months of anticoagulant treatment for dvt and/or pe following the acute event. the intended treatment duration in the study was up to 12 months. patients with an indication for continued therapeutic-dose anticoagulation were excluded. because the benefit-risk assessment favored the 10 mg dose versus aspirin compared to the 20 mg dose versus aspirin, only the data concerning the 10 mg dose is discussed below. a total of 2275 patients were randomized and followed on study treatment for a mean of 290 days for the xarelto and aspirin treatment groups. the mean age was approximately 59 years. the population was 56% male, 70% caucasian, 14% asian and 3% black. in the einstein choice study, 51% of patients had dvt only, 33% had pe only, and 16% had pe and dvt combined. other risk factors included idiopathic vte (43%), previous episode of dvt/pe (17%), recent surgery or trauma (12%), prolonged immobilization (10%), use of estrogen containing drugs (5%), known thrombophilic conditions (6%), factor v leiden gene mutation (4%), or active cancer (3%). in the einstein choice study, xarelto 10 mg was demonstrated to be superior to aspirin 100 mg for the primary composite endpoint of time to first occurrence of recurrent dvt or non-fatal or fatal pe. table 14 displays the overall results for the primary composite endpoint and its components. table 14:primary composite endpoint and its components results for

elective total hip or knee replacement (record 1, 2, and 3) [nct00329628, nct00332020, nct00361894] studies. the two randomized, double-blind, clinical studies (record 1 and 2) in patients undergoing elective total hip replacement surgery compared xarelto 10 mg once daily starting at least 6 to 8 hours (about 90% of patients dosed 6 to 10 hours) after wound closure versus enoxaparin 40 mg once daily started 12 hours preoperatively. in record 1 and 2, a total of 6727 patients were randomized and 6579 received study drug. the mean age [± standard deviation (sd)] was 63 ± 12.2 (range 18 to 93) years with 49% of patients ≥65 years and 55% of patients were female. more than 82% of patients were white, 7% were asian, and less than 2% were black. the studies excluded patients undergoing staged bilateral total hip replacement, patients with severe renal impairment defined as an estimated creatinine clearance <30 ml/min, or patients with significant liver disease (hepatitis or cirrhosis). in record 1, the mean exposure duration (± sd) to active xarelto and enoxaparin was 33.3 ± 7.0 and 33.6 ± 8.3 days, respectively. in record 2, the mean exposure duration to active xarelto and enoxaparin was 33.5 ± 6.9 and 12.4 ± 2.9 days, respectively. after day 13, oral placebo was continued in the enoxaparin group for the remainder of the double-blind study duration. the efficacy data for record 1

thromboembolic complications not at high risk of bleeding the efficacy and safety of xarelto for prophylaxis of venous thromboembolism in acutely ill medical patients at risk for thromboembolic complications not at high risk of bleeding was evaluated in the magellan study ( m ulticenter, r a ndomized, parallel g roup e fficacy and safety study for the prevention of venous thromboembolism in hospitalized medically i ll patients comparing rivaroxab an with enoxaparin [nct00571649]). magellan was a multicenter, randomized, double-blind, parallel-group efficacy and safety study comparing xarelto to enoxaparin, in the prevention of vte in hospitalized acutely ill medical patients during the in-hospital and post-hospital discharge period. eligible patients included adults who were at least 40 years of age, hospitalized for an acute medical illness, at risk of vte due to moderate or severe immobility, and had additional risk factors for vte. the population at risk of vte was required to have one or more of the following vte risk factors, i.e. prolonged immobilization, age ≥75 years, history of cancer, history of vte, history of heart failure, thrombophilia, acute infectious disease contributing to the hospitalization and bmi ≥35 kg/m 2 ). the causes for hospitalization included heart failure, active cancer, acute ischemic stroke, acute infectious and inflammatory disease and acute respiratory insufficiency. patients were randomized to receive either xarelto 10 mg once daily for 35 ±4 days starting in hospital and continuing post hospital discharge (n=4050) or enoxaparin 40 mg once daily for 10 ±4 days starting in hospital followed by placebo post-discharge (n=4051). the major efficacy outcome in the magellan trial was a composite endpoint that included asymptomatic proximal deep venous thrombosis (dvt) in lower extremity, symptomatic proximal or distal dvt in the lower extremity, symptomatic non-fatal pulmonary embolism (pe), and death related to venous thromboembolism (vte). a total of 6024 patients were evaluable for the major efficacy outcome analysis (2967 on xarelto 10 mg once daily and 3057 on enoxaparin/placebo). the mean age was 68.9 years, with 37.1% of the subject population ≥ 75 years. vte risk factors included severe immobilization at study entry (99.9%), d-dimer > 2× uln (43.7%), history of heart failure (35.6%), bmi ≥ 35 kg/m 2 (15.2%), chronic venous insufficiency (14.9%), acute infectious disease (13.9%), severe varicosis (12.5%), history of cancer (16.2%), history of vte (4.5%), hormone replacement therapy (1.1%), and thrombophilia (0.3%), recent major surgery (0.8%) and recent serious trauma (0.2%). the population was 54.7% male, 68.2% white, 20.4% asian, 1.9% black and 5.3% other. admitting diagnoses for hospitalization were acute infectious diseases (43.8%) followed by congestive heart failure nyha class iii or iv (33.2%), acute respiratory insufficiency (26.4%), acute ischemic stroke (18.5%) and acute inflammatory diseases (3.4%). table 17 shows the overall results from the prespecified, modified intent-to-treat (mitt) analysis for the efficacy outcomes and their components. this analysis excludes approximately 25% of the patients mainly due to no ultrasonographic assessment (13.5%), inadequate assessment at day 35 (8.1%), or lack of intake of study medication (1.3%). table 17:

cardiovascular events in patients with cad the evidence for the efficacy and safety of xarelto for the reduction in the risk of stroke, myocardial infarction, or cardiovascular death in patients with coronary artery disease (cad) or peripheral artery disease (pad) was derived from the double-blind, placebo-controlled c ardiovascular o utco m es for p eople using a nticoagulation s trategie s trial (compass) [nct10776424]. a total of 27,395 patients were evenly randomized to rivaroxaban 2.5 mg orally twice daily plus aspirin 100 mg once daily, rivaroxaban 5 mg orally twice daily alone, or aspirin 100 mg once daily alone. because the 5 mg dose alone was not superior to aspirin alone, only the data concerning the 2.5 mg dose plus aspirin are discussed below. patients with established cad or pad were eligible. patients with cad who were younger than 65 years of age were also required to have documentation of atherosclerosis involving at least two vascular beds or to have at least two additional cardiovascular risk factors (current smoking, diabetes mellitus, an estimated glomerular filtration rate [egfr] <60 ml per minute, heart failure, or non-lacunar ischemic stroke ≥1 month earlier). patients with pad were either symptomatic with ankle brachial index <0.90 or had asymptomatic carotid artery stenosis ≥50%, a previous carotid revascularization procedure, or established ischemic disease of one or both lower extremities. patients were excluded for use of dual antiplatelet, other non-aspirin antiplatelet, or oral anticoagulant therapies, ischemic, non-lacunar stroke within 1 month, hemorrhagic or lacunar stroke at any time, or egfr <15 ml/min. the mean age was 68 years and 21% of the subject population were ≥75 years. of the included patients, 91% had cad (and will be referred to as the compass cad population), 27% had pad (and will be referred to as the compass pad population), and 18% had both cad and pad. of the patients with cad, 69% had prior mi, 60% had prior percutaneous transluminal coronary angioplasty (ptca)/atherectomy/ percutaneous coronary intervention (pci), and 26% had history of coronary artery bypass grafting (cabg) prior to study. of the patients with pad, 49% had intermittent claudication, 27% had peripheral artery bypass surgery or peripheral percutaneous transluminal angioplasty, 26% had asymptomatic carotid artery stenosis > 50%, and 4% had limb or foot amputation for arterial vascular disease. the mean duration of follow-up was 23 months. relative to placebo, xarelto reduced the rate of the primary composite outcome of stroke, myocardial infarction or cardiovascular death: hr 0.76 (95% ci: 0.66, 0.86; p=0.00004). in the compass cad population, the benefit was observed early with a constant treatment effect over the entire treatment period (see table 19 and figure 10 ). a benefit-risk analysis of the data from compass was performed by comparing the number of cv events (cv deaths, myocardial infarctions and non-hemorrhagic strokes) prevented to the number of fatal or life-threatening bleeding events (fatal bleeds + symptomatic non-fatal bleeds into a critical organ) in the xarelto group versus the placebo group. compared to placebo, during 10,000 patient-years of treatment, xarelto would be expected to result in 70 fewer cv events and 12 additional life-threatening bleeds, indicating a favorable balance of benefits and risks. the results in the compass cad population were consistent across major subgroups (see figure 9 ). figure 9: risk of primary efficacy outcome by baseline

risk of major thrombotic vascular events in patients with pad, including patients after lower extremity revascularization due to symptomatic pad the efficacy and safety of xarelto 2.5 mg orally twice daily versus placebo on a background of aspirin 100 mg once daily in patients with pad were evaluated in the compass study (n=4996) and will be referred to as the compass pad population [see clinical studies (14.6) ] . the efficacy and safety of xarelto were also evaluated for the reduction in the risk of the composite endpoint of myocardial infarction, ischemic stroke, cardiovascular death, acute limb ischemia (ali), and major amputation of a vascular etiology in patients undergoing a lower extremity infrainguinal revascularization procedure due to symptomatic peripheral artery disease (pad) in the double-blinded, placebo-controlled v ascular o utcomes stud y of a sa alon g with rivaroxaban in e ndovascular or surgical limb r evascularization for peripheral artery disease (pad) trial (voyager) [nct02504216]. a total of 6,564 patients were equally randomized to xarelto 2.5 mg orally twice daily vs placebo on a background therapy of aspirin 100 mg once daily. eligible patients included adults who were at least 50 years of age with documented moderate to severe symptomatic lower extremity atherosclerotic pad who had a successful peripheral surgical procedure and/or endovascular procedure with or without clopidogrel (up to a maximum of 6 months was allowed; median duration of therapy was 31 days). patients had either a prior history of limb revascularization with ankle brachial index ≤0.85 or no prior history of limb revascularization with ankle brachial index ≤0.80. patients in need of dual antiplatelet for >6 months, or any additional antiplatelet other than aspirin and clopidogrel, or oral anticoagulant, as well as patients with a history of intracranial hemorrhage, stroke, or transient ischemic attack (tia), or patients with egfr <15 ml/min were excluded. the mean age was 67 years and 20% of the subject population was ≥75 years. of the included patients, 35% had surgical revascularization, 47% had endovascular revascularization with clopidogrel, and 18% endovascular revascularization without clopidogrel. the median duration of follow-up was 30.8 months. xarelto 2.5 mg twice daily was superior to placebo in reducing the rate of the primary composite outcome of myocardial infarction, ischemic stroke, cardiovascular death, acute limb ischemia (ali), and major amputation of a vascular etiology. the primary efficacy outcome and its components are provided in table 20. the kaplan-meier plot for the primary efficacy outcome can be seen in figure 11. the secondary efficacy outcomes were tested for superiority in a prespecified, hierarchical order and the first five of seven endpoints were significantly reduced in the rivaroxaban treatment arm (see table 20 ). compared to placebo during 10,000 patient-years of treatment, xarelto would be expected to result in 181 fewer primary outcome events and 29 more timi major bleeding events, indicating a favorable balance of benefits and risks. figure 11: time to first occurrence of primary efficacy outcome (myocardial infarction, ischemic stroke, cardiovascular death, acute limb ischemia, major amputation due to vascular origins) in voyager all patients received aspirin 100 mg once daily as background therapy. figure 12 shows the risk of primary efficacy outcome across major subgroups. subgroup analyses must be interpreted cautiously, as differences can reflect the play of chance among a large number of analyses. the primary efficacy endpoint generally shows homogeneous results across subgroups. figure 12: risk of primary efficacy outcome by baseline
