Xarelto Drug Information

• Recommended Dosage in Adults Table 1: Recommended Dosage in Adults Indication Renal Considerations Calculate CrCl based on actual weight. mL/min were not studied, but administration of XARELTO is expected to result in serum concentrations of rivaroxaban similar to those in patients with moderate renal impairment CrCl in Pediatric Patients Treatment of Venous Thromboembolism and Reduction in Risk of Recurrent Venous Thromboembolism in Pediatric Patients Table 2: Recommended Dosage in Pediatric Patients Birth to Less than 18 Years for Treatment of and Reduction in Risk of Recurrent VTE Initiate XARELTO treatment following at least 5 days of initial parenteral anticoagulation therapy., Patients <6 months of age should meet the following criteria: at birth were at least 37 weeks of gestation, have had at least 10 days of oral feeding, and weigh ≥2.6 kg at the time of dosing. Dosing of XARELTO was not studied and therefore dosing cannot be reliably determined in the following patient populations. Its use is therefore not recommended in children less than 6 months of age with any of the following: Less than 37 weeks of gestation at birth Less than 10 days of oral feeding Body weight of less than 2.6 kg. To increase absorption, all doses should be taken with feeding or with food. Monitor the child's weight and review the dose regularly, especially for children below 12 kg. This is to ensure a therapeutic dose is maintained. All pediatric patients (except <2 years old with catheter-related thrombosis): Therapy with XARELTO should be continued for at least 3 months in children with thrombosis. Treatment can be extended up to 12 months when clinically necessary. The benefit of continued therapy beyond 3 months should be assessed on an individual basis taking into account the risk for recurrent thrombosis versus the potential risk of bleeding. Pediatric patients <2 years old with catheter-related thrombosis: Therapy with XARELTO should be continued for at least 1 month in children less than 2 years old with catheter-related thrombosis. Thromboprophylaxis in Pediatric Patients with Congenital Heart Disease after the Fontan Procedure Table 3: Recommended Dosage for Thromboprophylaxis in Pediatric Patients with Congenital Heart Disease Administration in Pediatric Patients Food Effect: For the treatment of VTE in children, the dose should be taken with food to increase absorption. For thromboprophylaxis after Fontan procedure, the dose can be taken with or without food.
• Vomit or Spit up: If the patient vomits or spits up the dose within 30 minutes after receiving the dose, a new dose should be given. However, if the patient vomits more than 30 minutes after the dose is taken, the dose should not be re-administered and the next dose should be taken as scheduled. If the patient vomits or spits up the dose repeatedly, the caregiver should contact the child's doctor right away.
• Tablets: XARELTO tablet must not be split in an attempt to provide a fraction of a tablet dose. For children unable to swallow 10, 15, or 20 mg whole tablets, XARELTO oral suspension should be used. XARELTO 2.5 mg tablets are not recommended for use in pediatric patients.
• Moderate or severe renal impairment (eGFR:<50 mL/min/1.73 m 2 ): avoid use, as limited clinical data are available. Estimated glomerular filtration rate (eGFR) can be done using the updated Schwartz formula, eGFR (Schwartz) = (0.413 × height in cm)/serum creatinine in mg/dL, if serum creatinine (SCr) is measured by an enzymatic creatinine method that has been calibrated to be traceable to isotope dilution mass spectrometry (IDMS). If SCr is measured with routine methods that have not been recalibrated to be traceable to IDMS (e.g., the traditional Jaffé reaction), the eGFR should be obtained from the original Schwartz formula: eGFR (mL/min/1.73 m 2 ) = k height (cm)/SCr (mg/dL), where k is proportionality constant: k = 0.55 in children 1 year to 13 years k = 0.55 in girls > 13 and < 18 years k = 0.70 in boys > 13 and < 18 years Patients Less than 1 Year of Age Determine renal function using serum creatinine. Avoid use of XARELTO in pediatric patients younger than 1 year with serum creatinine results above 97.5 th percentile, as no clinical data are available.

Switching to and from XARELTO Switching from Warfarin to XARELTO - When switching patients from warfarin to XARELTO, discontinue warfarin and start XARELTO as soon as the International Normalized Ratio (INR) is below 3.0 in adults and below 2.5 in pediatric patients to avoid periods of inadequate anticoagulation. Switching from XARELTO to Warfarin – Adults: 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. Pediatric Patients: To ensure adequate anticoagulation during the transition from XARELTO to warfarin, continue XARELTO for at least 2 days after the first dose of warfarin. After 2 days of co-administration, an INR should be obtained prior to the next scheduled dose of XARELTO.

Co-administration of XARELTO and warfarin is advised to continue until the INR is ≥ 2.0. Once XARELTO is discontinued, INR testing may be done reliably 24 hours after the last dose. Switching from XARELTO to Anticoagulants other than Warfarin - For adult and pediatric 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.

Switching from Anticoagulants other than Warfarin to XARELTO - For adult and pediatric patients currently receiving an anticoagulant other than warfarin, start XARELTO 0 to 2 hours prior to the next scheduled 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.

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. 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.

If oral medication cannot be taken during or after surgical intervention, consider administering a parenteral anticoagulant.

Missed Dose Adults

• 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. Pediatric Patients If XARELTO is taken once a day, the patient should take the missed dose as soon as possible once it is noticed, but only on the same day. If this is not possible, the patient should skip the dose and continue with the next dose as prescribed. The patient should not take two doses to make up for a missed dose. If XARELTO is taken two times a day, the patient should take the missed morning dose as soon as possible once it is noticed. A missed morning dose may be taken together with the evening dose. A missed evening dose can only be taken in the same evening. If XARELTO is taken three times a day, if a dose is missed, the patient should skip the missed dose and go back to the regular dosing schedule at the usual time without compensating for the missed dose. On the following day, the patient should continue with their regular regimen.

Administration Options

For adult 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.

Administration of XARELTO tablets 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. Enteral feeding is not required following administration of the 2.5 mg or 10 mg tablets.

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. Administration of XARELTO suspension via NG tube or gastric feeding tube: XARELTO oral suspension may be given through NG or gastric feeding tube.

After the administration, flush the feeding tube with water. For the treatment or reduction in risk of recurrent VTE in pediatric patients, the dose should then be immediately followed by enteral feeding to increase absorption. For the thromboprophylaxis in pediatric patients with congenital heart disease who have undergone the Fontan procedure, the dose does not require to be followed by enteral feeding.

An in vitro compatibility study indicated that XARELTO suspension can be used with PVC, polyurethane or silicone NG tubing.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. During clinical development for the approved indications, 34,947 adult patients were exposed to XARELTO. Hemorrhage The most common adverse reactions with XARELTO were bleeding complications.

Nonvalvular Atrial Fibrillation In the ROCKET AF trial, the most frequent adverse reactions associated with permanent drug discontinuation were bleeding events, with incidence rates of 4.3% for XARELTO vs. 3.1% for warfarin. The incidence of discontinuations for non-bleeding adverse events was similar in both treatment groups. Table 5 shows the number of patients experiencing various types of bleeding events in the ROCKET AF trial.

Table 5: Bleeding Events in ROCKET AF Major bleeding events within each subcategory were counted once per patient, but patients may have contributed events to multiple subcategories. These events occurred during treatment or within 2 days of stopping treatment. - On Treatment Plus Figure 1 shows the risk of major bleeding events across major subgroups. Figure 1: Risk of Major Bleeding Events by Baseline Characteristics in ROCKET AF – On Treatment Plus 2 Days Treatment of Deep Vein Thrombosis (DVT) and/or Pulmonary Embolism (PE) EINSTEIN DVT and EINSTEIN PE Studies In the pooled analysis of the EINSTEIN DVT and EINSTEIN PE clinical studies, the most frequent adverse reactions leading to permanent drug discontinuation were bleeding events, with XARELTO vs. enoxaparin/Vitamin K antagonist (VKA) incidence rates of 1.7% vs. 1.5%, respectively.

The mean duration of treatment was 208 days for XARELTO-treated patients and 204 days for enoxaparin/VKA-treated patients. Table 6 shows the number of patients experiencing major bleeding events in the pooled analysis of the EINSTEIN DVT and EINSTEIN PE studies. Table 6: Bleeding Events Bleeding event occurred after randomization and up to 2 days after the last dose of study drug.

Although a patient may have had 2 or more events, the patient is counted only once in a category. in the Pooled Analysis of EINSTEIN DVT and EINSTEIN PE Studies Parameter XARELTO Treatment schedule in EINSTEIN DVT and EINSTEIN PE studies: XARELTO 15 mg twice daily for 3 weeks followed by 20 mg once daily; enoxaparin/VKA N=4130 1169 1153 Reduction in the Risk of Recurrence of DVT and/or PE EINSTEIN CHOICE Study In the EINSTEIN CHOICE clinical study, the most frequent adverse reactions associated with permanent drug discontinuation were bleeding events, with incidence rates of 1% for XARELTO 10 mg, 2% for XARELTO 20 mg, and 1% for acetylsalicylic acid (aspirin) 100 mg. Table 7 shows the number of patients experiencing bleeding events in the EINSTEIN CHOICE study. Although a patient may have had 2 or more events, the patient is counted only once in a category. in EINSTEIN CHOICE 151 138 In the EINSTEIN CHOICE study, there was an increased incidence of bleeding, including major and CRNM bleeding in the XARELTO 20 mg group compared to the XARELTO 10 mg or aspirin 100 mg groups.

Prophylaxis of Deep Vein Thrombosis Following Hip or Knee Replacement Surgery In the RECORD clinical trials, the overall incidence rate of adverse reactions leading to permanent treatment discontinuation was 3.7% with XARELTO. The rates of major bleeding events and any bleeding events observed in patients in the RECORD clinical trials are shown in Table 8. Table 8: Bleeding Events Bleeding events occurring any time following the first dose of double-blind study medication (which may have been prior to administration of active drug) until two days after the last dose of double-blind study medication.

Patients may have more than one event. in Patients Undergoing Hip or Knee Replacement Surgeries (RECORD 1–3) 60 60 Following XARELTO treatment, the majority of major bleeding complications (≥60%) occurred during the first week after surgery. Prophylaxis of Venous Thromboembolism in Acutely Ill Medical Patients at Risk for Thromboembolic Complications Not at High Risk of Bleeding In the MAGELLAN study, the most frequent adverse reactions associated with permanent drug discontinuation were bleeding events. Cases of pulmonary hemorrhage and pulmonary hemorrhage with bronchiectasis were observed.

Patients with bronchiectasis/pulmonary cavitation, active cancer (i.e., undergoing acute, in-hospital cancer treatment), dual antiplatelet therapy or active gastroduodenal ulcer or any bleeding in the previous three months all had an excess of bleeding with XARELTO compared with enoxaparin/placebo and are excluded from all MAGELLAN data presented in Table 9. The incidence of bleeding leading to drug discontinuation was 2.5% for XARELTO vs. 1.4% for enoxaparin/placebo. Table 9 shows the number of patients experiencing various types of bleeding events in the MAGELLAN study.

Table 9: Bleeding Events in MAGELLAN Patients at high risk of bleeding (i.e. bronchiectasis/pulmonary cavitation, active cancer, dual antiplatelet therapy or active gastroduodenal ulcer or any bleeding in the previous three months) were excluded. Study–Safety Analysis Set - On Treatment Plus 2 Days 93 34 Reduction of Risk of Major Cardiovascular Events in Patients with CAD In the COMPASS trial overall, the most frequent adverse reactions associated with permanent drug discontinuation were bleeding events, with incidence rates of 2.7% for XARELTO 2.5 mg twice daily vs. 1.2% for placebo on background therapy for all patients with aspirin 100 mg once daily. The incidences of important bleeding events in the CAD and PAD populations in COMPASS were similar.

Table 10 shows the number of patients experiencing various types of major bleeding events in the COMPASS trial. Table 10: Major Bleeding Events in COMPASS - On Treatment Plus 2 Days Major bleeding events within each subcategory were counted once per patient, but patients may have contributed events to multiple subcategories. These events occurred during treatment or within 2 days of stopping treatment in the safety analysis set in COMPASS patients. 117 49 2.4 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 The incidence of premature permanent discontinuation due to bleeding events for XARELTO 2.5 mg twice daily vs. placebo on background therapy with aspirin 100 mg once daily in VOYAGER was 4.1% vs. 1.6% and in COMPASS PAD was 2.7% vs. 1.3%, respectively.

Table 11 shows the number of patients experiencing various types of TIMI (Thrombolysis in Myocardial Infarction) major bleeding events in the VOYAGER trial. The most common site of bleeding was gastrointestinal. Patients were randomized 2:1 to receive body weight-adjusted doses of XARELTO or comparator (unfractionated heparin, low molecular weight heparin, fondaparinux or VKA).

Table 14 shows the number of patients experiencing bleeding events in the EINSTEIN Junior study. Table 14: Bleeding Events in EINSTEIN Junior Study – Safety Analysis Set - Main Treatment Period These events occurred after randomization until 3 months of treatment 1 month for patients <2 years with central venous catheter-related VTE (CVC-VTE). Table 15: Other Adverse Reactions Adverse reaction with Relative Risk >1.5 for XARELTO versus comparator.

Thromboprophylaxis in Pediatric Patients with Congenital Heart Disease (CHD) after the Fontan Procedure The data below are based on Part B of the UNIVERSE study which was designed to evaluate the safety and efficacy of XARELTO for thromboprophylaxis in 98 children with CHD after the Fontan procedure who took at least one dose of study drug. Patients in Part B were randomized 2:1 to receive either body weight-adjusted doses of XARELTO or aspirin (approximately 5 mg/kg). Discontinuation due to bleeding events occurred in 1 (1.6%) patient in the XARELTO group and no patients in the aspirin group.

Table 16 shows the number of patients experiencing bleeding events in the UNIVERSE study. Table 17: Other Adverse Reactions Adverse reaction with Relative Risk >1.5 for XARELTO versus aspirin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Blood and lymphatic system disorders: agranulocytosis, thrombocytopenia Hepatobiliary disorders: jaundice, cholestasis, hepatitis (including hepatocellular injury) Immune system disorders: hypersensitivity, anaphylactic reaction, anaphylactic shock, angioedema Nervous system disorders: hemiparesis Renal disorders: Anticoagulant-related nephropathy Respiratory, thoracic and mediastinal disorders: Eosinophilic pneumonia Skin and subcutaneous tissue disorders: Stevens-Johnson syndrome, drug reaction with eosinophilia and systemic symptoms (DRESS) Injury, poisoning and procedural complications: Atraumatic splenic rupture

General Inhibition and Induction Properties Rivaroxaban is a substrate of CYP3A4/5, CYP2J2, and the P-gp and ATP-binding cassette G2 (ABCG2) transporters, the latter also known as breast cancer resistance protein (BCRP). Combined P-gp and strong CYP3A inhibitors increase exposure to rivaroxaban and may increase the risk of bleeding. Combined P-gp and strong CYP3A inducers decrease exposure to rivaroxaban and may increase the risk of thromboembolic events.

Drugs that Inhibit Cytochrome P450 3A Enzymes and Drug Transport Systems Interaction with Combined P-gp and Strong CYP3A Inhibitors Avoid concomitant administration of XARELTO with known combined P-gp and strong CYP3A inhibitors (e.g., ketoconazole and ritonavir). Although clarithromycin is a combined P-gp and strong CYP3A inhibitor, pharmacokinetic data suggests that no precautions are necessary with concomitant administration with XARELTO as the change in exposure is unlikely to affect the bleeding risk. 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.

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).

Anticoagulants and NSAIDs/Aspirin Coadministration of enoxaparin, warfarin, aspirin, clopidogrel and chronic NSAID use may increase the risk of bleeding. 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.

Pregnancy Risk Summary The limited available data on XARELTO in pregnant women are insufficient to inform a drug-associated risk of adverse developmental outcomes. Use XARELTO with caution in pregnant patients because of the potential for pregnancy related hemorrhage and/or emergent delivery. The anticoagulant effect of XARELTO cannot be reliably monitored with standard laboratory testing.

Consider the benefits and risks of XARELTO for the mother and possible risks to the fetus when prescribing XARELTO to a pregnant woman. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. The estimated background risk of major birth defects and miscarriage for the indicated populations is 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.

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. 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).

Pediatric Use The safety and effectiveness of XARELTO have been established in pediatric patients from birth to less than 18 years for the treatment of VTE and the reduction in risk of recurrent VTE. Use of XARELTO is supported in these age groups by evidence from adequate and well-controlled studies of XARELTO in adults with additional pharmacokinetic, safety and efficacy data from a multicenter, prospective, open-label, active-controlled randomized study in 500 pediatric patients from birth to less than 18 years of age. XARELTO was not studied and therefore dosing cannot be reliably determined or recommended in children less than 6 months who were less than 37 weeks of gestation at birth; had less than 10 days of oral feeding, or had a body weight of less than 2.6 kg.

The safety and effectiveness of XARELTO have been established for use in pediatric patients aged 2 years and older with congenital heart disease who have undergone the Fontan procedure. Use of XARELTO is supported in these age groups by evidence from adequate and well-controlled studies of XARELTO in adults with additional data from a multicenter, prospective, open-label, active controlled study in 112 pediatric patients to evaluate the single- and multiple-dose pharmacokinetic properties of XARELTO and the safety and efficacy of XARELTO when used for thromboprophylaxis for 12 months in children with single ventricle physiology who had the Fontan procedure. Clinical studies that evaluated safety, efficacy, pharmacokinetic and pharmacodynamic data support the use of XARELTO 10 mg, 15 mg, and 20 mg tablets in pediatric patients.

For the XARELTO 2.5 mg tablets, there are no safety, efficacy, pharmacokinetic and pharmacodynamic data to support the use in pediatric patients. Therefore, XARELTO 2.5 mg tablets are not recommended for use in pediatric patients. Although not all adverse reactions identified in the adult population have been observed in clinical trials of children and adolescent patients, the same warnings and precautions for adults should be considered for children and adolescents.

XARELTO is contraindicated in patients with: active pathological bleeding severe hypersensitivity reaction to XARELTO (e.g., anaphylactic reactions) Active pathological bleeding Severe hypersensitivity reaction to XARELTO

Overdose of XARELTO may lead to hemorrhage. Discontinue XARELTO and initiate appropriate therapy if bleeding complications associated with overdosage occur. Rivaroxaban systemic exposure is not further increased at single doses >50 mg due to limited absorption.

The use of activated charcoal to reduce absorption in case of XARELTO overdose may be considered. Due to the high plasma protein binding, rivaroxaban is not dialyzable. Partial reversal of laboratory anticoagulation parameters may be achieved with use of plasma products.

A specific agent to reverse the anti-factor Xa activity of rivaroxaban is not available.
