ELIQUIS increases the risk of bleeding and can cause serious, potentially fatal bleeding. Please see additional Important Safety Information included in this release.“With a population that is living longer, the prevalence of nonvalvular atrial fibrillation is increasing, but many patients are still not being managed effectively with warfarin,” said Christopher Granger, M.D., Professor of Medicine, Duke Clinical Research Institute, Duke University Medical Center, Durham, N.C., ARISTOTLE lead investigator. “ELIQUIS represents a significant advance over warfarin for health care professionals to reduce the risk of stroke in patients with nonvalvular atrial fibrillation.” ELIQUIS is an oral Factor Xa inhibitor anticoagulant. By inhibiting Factor Xa, a key blood clotting protein, ELIQUIS decreases thrombin generation and blood clot formation. ELIQUIS does not require routine monitoring using International Normalized Ratio (INR) or other tests of coagulation and there are no known dietary restrictions. ELIQUIS can be taken with or without food. ELIQUIS is expected to be widely available in the U.S. by the end of January 2013. Efficacy and Safety Profile of ELIQUIS in Patients with Nonvalvular Atrial Fibrillation The ARISTOTLE (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation) study was designed to compare the effects of ELIQUIS and warfarin on the risk of stroke and systemic embolism. In ARISTOTLE, 18,201 patients were randomized (9,120 patients to ELIQUIS and 9,081 to warfarin) and were followed for a median of 1.7 years. ARISTOTLE was a double-blind, multi-national trial in patients with nonvalvular atrial fibrillation, and one or more of the following additional risk factors for stroke: prior stroke or transient ischemic attack, prior systemic embolism, age ≥75 years, arterial hypertension requiring treatment, diabetes mellitus, heart failure ≥New York Heart Association Class 2, or left ventricular ejection fraction ≤40%. Patients received treatment with ELIQUIS 5 mg orally twice daily (or 2.5 mg twice daily in patients with at least 2 of the following characteristics: age ≥80 years, body weight ≤60 kg, or serum creatinine ≥1.5 mg/dL) or warfarin (target INR range 2.0-3.0).
ELIQUIS is the only oral anticoagulant to demonstrate superior risk reductions versus warfarin in three key outcomes—stroke and systemic embolism, major bleeding, and all-cause mortality—for patients with nonvalvular atrial fibrillation.In ARISTOTLE, ELIQUIS was superior to warfarin in the primary efficacy endpoint of stroke or systemic embolism, with a 21% relative risk reduction beyond warfarin (1.27%/year versus 1.60%/year, HR=0.79, p=0.01). Superiority to warfarin was primarily attributable to a reduction in hemorrhagic stroke and ischemic stroke that converted to hemorrhagic stroke. Purely ischemic strokes occurred with similar rates on both drugs. ELIQUIS was superior to warfarin for the primary safety endpoint of major bleeding, with a 31% relative risk reduction (2.13%/year versus 3.09%/year, HR=0.69, p<0.0001). Major bleeding was defined as clinically overt bleeding that was accompanied by one or more of the following: a decrease in hemoglobin of 2 g/dL or more; a transfusion of 2 or more units of packed red blood cells; bleeding that occurred in at least one of the following critical sites: intracranial, intraspinal, intraocular, pericardial, intra-articular, intramuscular with compartment syndrome, retroperitoneal; or bleeding that was fatal. The incidence of major gastrointestinal (GI) bleeds was lower with ELIQUIS compared to warfarin (0.83%/year versus 0.93%/year, HR=0.89 [CI=0.70, 1.14]). GI bleed includes upper GI, lower GI, and rectal bleeding. ELIQUIS demonstrated a significant reduction in intracranial hemorrhage versus warfarin with a 59% relative risk reduction (0.33%/year versus 0.82%/year, HR=0.41 [CI=0.30, 0.57]). Intracranial hemorrhage included intracerebral (hemorrhagic stroke), subarachnoid, and subdural bleeds. The incidence of major intraocular bleeding was numerically higher with ELIQUIS compared to warfarin (0.21%/year versus 0.14%/year, HR=1.42 [CI=0.83, 2.45]). Intraocular bleed is within the corpus of the eye (a conjunctival bleed is not an intraocular bleed). ELIQUIS demonstrated a significant reduction in fatal bleeds versus warfarin with a 73% relative risk reduction (0.06%/year versus 0.24%/year, HR=0.27 [CI=0.13, 0.53]). Fatal bleed is an adjudicated death because of bleeding during the treatment period and includes both fatal extracranial bleeds and fatal hemorrhagic stroke. Eliquis demonstrated a significant reduction in clinically relevant non major bleeding (CRNM) versus warfarin (2.08%/year for ELIQUIS compared to 3.00%/year for warfarin [HR= 0.70, P<0.0001]). CRNM was defined as clinically overt bleeding that did not satisfy the criteria for major bleeding and that led to hospital admission, physician-guided medical or surgical treatment, or a change in antithrombotic therapy.
In AVERROES, ELIQUIS was associated with an increase in major bleeding compared to aspirin that was not statistically significant (1.41%/year versus 0.92%/year, HR 1.54, (95% CI, 0.96 to 2.45); P = 0.07).ELIQUIS was superior to warfarin in the key secondary endpoint of all-cause mortality, with an 11% relative risk reduction (3.5%/year versus 3.9%/year, HR=0.89, p= 0.046), primarily because of a reduction in cardiovascular death, particularly stroke deaths. Non-vascular death rates were similar in the treatment arms. The most common and most serious adverse reactions observed in the ARISTOTLE and AVERROES clinical trials with ELIQUIS were related to bleeding. The most common reason for treatment discontinuation was for bleeding-related adverse reactions; in ARISTOTLE, this occurred in 1.7% and 2.5% of patients treated with ELIQUIS and warfarin, respectively. Patients taking ELIQUIS should be carefully observed and counseled on the symptoms and signs of bleeding. The FDA has determined that a Risk Evaluation and Mitigation Strategy (REMS) is necessary to ensure that the benefits of ELIQUIS outweigh the potential risks in patients with nonvalvular atrial fibrillation. The ELIQUIS REMS consists of a communication plan to inform healthcare professionals about the increased risk of thrombotic events, including stroke when discontinuing ELIQUIS without an adequate alternative anticoagulant and the importance of following the recommendations in the U.S. Prescribing Information on how to convert patients with nonvalvular atrial fibrillation from ELIQUIS to warfarin or other anticoagulants. ELIQUIS Dosage and Administration The recommended dose of ELIQUIS for most patients is 5 mg taken orally twice daily. In patients with any two of the following characteristics (age ≥80 years, body weight ≤60 kg, or serum creatinine ≥1.5mg/dL), the recommended dose of ELIQUIS is 2.5 mg twice daily. The dose of ELIQUIS should be decreased to 2.5 mg twice daily when coadministered with drugs that are strong dual inhibitors of CYP3A4 and P-gp, (e.g., ketoconazole, itraconazole, ritonavir, or clarithromycin). In patients already taking 2.5 mg twice daily, avoid coadministration of ELIQUIS with strong dual inhibitors of CYP3A4 and P-gp. ELIQUIS should be discontinued at least 48 hours prior to elective surgery or invasive procedures with a moderate or high risk of unacceptable or clinically significant bleeding. ELIQUIS should be discontinued at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding or where the bleeding would be non-critical in location and easily controlled. For more detailed information on the dosing of ELIQUIS, please refer to Section 2 of the Full Prescribing Information.
IMPORTANT SAFETY INFORMATION for ELIQUIS ® (apixaban) 2.5 mg and 5 mg tablets
|WARNING: DISCONTINUING ELIQUIS IN PATIENTS WITHOUT ADEQUATE CONTINUOUS ANTICOAGULATION INCREASES RISK OF STROKE.|
|Discontinuing ELIQUIS places patients at an increased risk of thrombotic events. An increased rate of stroke was observed following discontinuation of ELIQUIS in clinical trials in patients with nonvalvular atrial fibrillation. If anticoagulation with ELIQUIS must be discontinued for a reason other than pathological bleeding, coverage with another anticoagulant should be strongly considered .|
- Active pathological bleeding
- Severe hypersensitivity reaction to ELIQUIS (apixaban) (i.e., anaphylactic reactions)
- Increased Risk of Stroke with Discontinuation of ELIQUIS: Discontinuing ELIQUIS in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from ELIQUIS to warfarin in clinical trials in patients with nonvalvular atrial fibrillation. If ELIQUIS must be discontinued for a reason other than pathological bleeding, consider coverage with another anticoagulant.
- Bleeding Risk: ELIQUIS increases the risk of bleeding and can cause serious, potentially fatal bleeding. Concomitant use of drugs affecting hemostasis increases the risk of bleeding including aspirin and other anti-platelet agents, other anticoagulants, heparin, thrombolytic agents, SSRIs, SNRIs, and NSAIDs. Patients should be made aware of signs or symptoms of blood loss and instructed to immediately report to an emergency room. Discontinue ELIQUIS in patients with active pathological hemorrhage.
- There is no established way to reverse the anticoagulant effect of apixaban, which can be expected to persist for about 24 hours after the last dose (i.e., about two half-lives). A specific antidote for ELIQUIS is not available. Because of high plasma protein binding, apixaban is not expected to be dialyzable. Protamine sulfate and vitamin K would not be expected to affect the anticoagulant activity of apixaban. There is no experience with antifibrinolytic agents (tranexamic acid, aminocaproic acid) in individuals receiving apixaban. There is neither scientific rationale for reversal nor experience with systemic hemostatics (desmopressin and aprotinin) in individuals receiving apixaban. Use of procoagulant reversal agents such as prothrombin complex concentrate, activated prothrombin complex concentrate, or recombinant factor VIIa may be considered but has not been evaluated in clinical studies. Activated charcoal reduces absorption of apixaban thereby lowering apixaban plasma concentrations.
- Prosthetic Heart Valves: The safety and efficacy of ELIQUIS has not been studied in patients with prosthetic heart valves and is not recommended in these patients.
DISCONTINUATIONS FOR SURGERY AND OTHER INTERVENTIONSELIQUIS should be discontinued at least 48 hours prior to elective surgery or invasive procedures with a moderate or high risk of unacceptable or clinically significant bleeding. ELIQUIS should be discontinued at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding or where the bleeding would be noncritical in location and easily controlled. DRUG INTERACTIONS
- Strong Dual Inhibitors of CYP3A4 and P-gp: Inhibitors of CYP3A4 and P-gp increase exposure to apixaban and increase the risk of bleeding. Decrease the dose of ELIQUIS to 2.5 mg twice daily when coadministered with drugs that are strong dual inhibitors of CYP3A4 and P-gp, (e.g., ketoconazole, itraconazole, ritonavir, or clarithromycin). In patients already taking ELIQUIS at a dose of 2.5 mg daily, avoid coadministration with strong dual inhibitors of CYP3A4 and P-gp.
- Strong Dual Inducers of CYP3A4 and P-gp: Inducers of CYP3A4 and P-gp decrease exposure to apixaban and increase the risk of stroke. Avoid concomitant use of ELIQUIS with strong dual inducers of CYP3A4 and P-gp (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort) because such drugs will decrease exposure to apixaban.
- Anticoagulants and Antiplatelet Agents: Coadministration of antiplatelet agents, fibrinolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding.
