Rivaroxaban

12.1 Mechanism of Action XARELTO is a selective inhibitor of FXa. It does not require a cofactor (such as Anti-thrombin III) for activity. Rivaroxaban inhibits free FXa and prothrombinase activity. Rivaroxaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting FXa, rivaroxaban decreases thrombin generation.

1 INDICATIONS AND USAGE XARELTO is a factor Xa inhibitor indicated: to reduce risk of stroke and systemic embolism in nonvalvular atrial fibrillation ( 1.1 ) for treatment of deep vein thrombosis (DVT) ( 1.2 ) for treatment of pulmonary embolism (PE) ( 1.3 ) for reduction in the risk of recurrence of DVT or PE ( 1.4 ) for the prophylaxis of DVT, which may lead to PE in patients undergoing knee or hip replacement surgery ( 1.5 ) for prophylaxis of venous thromboembolism (VTE) in acutely ill medical patients ( 1.6 ) to reduce the risk of major cardiovascular events in patients with coronary artery disease (CAD) ( 1.7 ) to reduce the risk of major thrombotic vascular events in patients with peripheral artery disease (PAD), including patients after recent lower extremity revascularization due to symptomatic PAD ( 1.8 ) for treatment of VTE and reduction in the risk of recurrent VTE in pediatric patients from birth to less than 18 years ( 1.9 ) for thromboprophylaxis in pediatric patients 2 years and older with congenital heart disease after the Fontan procedure ( 1.10 ) 1.1 Reduction of Risk of Stroke and Systemic Embolism in Nonvalvular Atrial Fibrillation XARELTO is indicated to reduce the risk of stroke and systemic embolism in adult 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 adult patients at continued risk for recurrent DVT and/or PE after completion of initial treatment lasting at l

6 ADVERSE REACTIONS The following clinically significant adverse reactions are also discussed in other sections of the labeling: Increased Risk of Stroke After Discontinuation in Nonvalvular Atrial Fibrillation [see Boxed Warning and Warnings and Precautions (5.1) ] Bleeding Risk [see Warnings and Precautions (5.2 , 5.4 , 5.5 , 5.6 , 5.7) ] Spinal/Epidural Hematoma [see Boxed Warning and Warnings and Precautions (5.3) ] The most common adverse reaction (>5%) in adult patients was bleeding. ( 6.1 ) The most common adverse reactions (>10%) in pediatric patients were bleeding, cough, vomiting, and gastroenteritis.

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 [see Warnings and Precautions (5.2) ] . 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 2 Days Parameter XARELTO N=7111 n (%/year) Warfarin N=7125 n (%/year) XARELTO vs. Warfarin HR (95% CI) Abbreviations: HR = Hazard Ratio, CI = Confidence interval, CRNM = Clinically Relevant Non-Major.

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.

The mean duration of treatment was 208 days for XARELTO-treated patients and 204 days for enoxaparin/VKA-treated patients.

7 DRUG INTERACTIONS Avoid combined P-gp and strong CYP3A inhibitors and inducers ( 7.2 , 7.3 ) Anticoagulants: Avoid concomitant use ( 7.4 ) 7.1 General Inhibition and Induction Properties Rivaroxaban is a substrate of CYP3A4/5, CYP2J2, and the P-gp and ATP-binding cassette G2 (ABCG2) transporters. 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. 7.2 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) [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3) ] . 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 [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) ] .
