In the study, Eliquis was shown to be non-inferior to enoxaparin/warfarin in the combined primary endpoint of adjudicated recurrent symptomatic VTE (nonfatal DVT or nonfatal PE) or VTE-related death.Eliquis efficacy in initial treatment of VTE was consistent between patients who were treated for a PE [Relative Risk 0.9; 95 percent CI (0.5, 1.6)] or DVT [Relative Risk 0.8; 95 percent CI (0.5, 1.3)]. Efficacy across subgroups, including age, gender, body mass index (BMI), renal function, extent of index PE, location of DVT thrombus, and prior parenteral heparin use was generally consistent. For patients randomized to warfarin, the mean percentage of time in therapeutic range (TTR) (INR 2.0-3.0) was 60.9. The effect of Eliquis on recurrent symptomatic VTE or VTE- related death was consistent across the different levels of center TTR; within the highest quartile of TTR according to center, the relative risk for Eliquis vs enoxaparin/warfarin was 0.79 (95 percent CI, 0.39, 1.61). The primary safety endpoint was major bleeding. In the study, Eliquis was statistically superior to enoxaparin/warfarin in the primary safety endpoint [Relative Risk 0.31, 95 percent confidence interval (0.17, 0.55), P-value <0.0001]. The adjudicated major bleeding and clinically relevant non-major (CRNM) bleeding at any anatomical site were generally lower in the Eliquis group as compared to the enoxaparin/warfarin group. Adjudicated International Society on Thrombosis and Haemostasis (ISTH) major gastrointestinal bleeding occurred in 6 (0.2 percent) Eliquis-treated patients and 17 (0.6 percent) enoxaparin/warfarin-treated patients. AMPLIFY- EXT As described in the SmPC, in the AMPLIFY-EXT study a total of 2,482 patients were randomized to treatment with Eliquis 2.5 mg twice daily orally, Eliquis 5 mg twice daily orally, or placebo for 12 months after completing six to 12 months of initial anticoagulant treatment. Of these, 836 patients (33.7 percent) participated in the AMPLIFY study prior to enrollment in the AMPLIFY-EXT study. The mean age was 56.7 years and 91.7 percent of randomized patients had unprovoked VTE events.
In the study, both doses of Eliquis were statistically superior to placebo in the primary endpoint of symptomatic, recurrent VTE (nonfatal DVT or nonfatal PE) or all-cause death.Eliquis efficacy for prevention of a recurrence of a VTE was maintained across subgroups, including age, gender, BMI, and renal function. The primary safety endpoint was major bleeding during the treatment period. In the study, the incidence in major bleeding for both Eliquis doses was not statistically different from placebo. There was no statistically significant difference in the incidence of major, clinically relevant non-major, minor, and all bleeding between the Eliquis 2.5 mg twice daily and placebo treatment groups. The recommended dose of Eliquis for the prevention of recurrent DVT and PE is 2.5 mg taken orally twice daily. Adjudicated ISTH major gastrointestinal bleeding occurred in 1 (0.1 percent) Eliquis-treated patient at the 5 mg twice daily dose, no patients at the 2.5 mg twice daily dose, and 1 (0.1 percent) placebo-treated patient. About Eliquis Eliquis (apixaban) is an oral selective Factor Xa inhibitor. By inhibiting Factor Xa, a key blood clotting protein, Eliquis decreases thrombin generation and blood clot formation. Eliquis is approved to reduce the risk of stroke and systemic embolism in adult patients with NVAF in the United States, European Union, Japan and a number of other countries around the world. Eliquis is approved for the prophylaxis of VTE in adult patients who have undergone elective hip or knee replacement surgery in the United States, European Union and a number of other countries around the world. Eliquis is not approved for this indication in Japan. Eliquis is approved for the treatment of DVT and PE, and prevention of recurrent DVT and PE in the European Union. Eliquis is not approved for this indication in the United States. IMPORTANT SAFETY INFORMATION FROM U.S. PRESCRIBING INFORMATION WARNINGS: (A) DISCONTINUING ELIQUIS IN PATIENTS WITH NONVALVULAR ATRIAL FIBRILLATION WITHOUT ADEQUATE CONTINUOUS ANTICOAGULATION INCREASES RISK OF STROKE, (B) SPINAL/EPIDURAL HEMATOMA (A) 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 . (B) When neuraxial anesthesia (epidural/spinal anesthesia) or spinal puncture is employed, patients anticoagulated or scheduled to be anticoagulated with low molecular weight heparins, heparinoids, or Factor Xa inhibitors for prevention of thromboembolic complications are at risk of developing an epidural or spinal hematoma which can result in long-term or permanent paralysis. The risk of these events may be increased by the use of indwelling epidural catheters for administration of analgesia or by the concomitant use of drugs affecting hemostasis such as nonsteroidal anti-inflammatory drugs (NSAIDs), platelet aggregation inhibitors, or other anticoagulants. The risk also appears to be increased by traumatic or repeated epidural or spinal puncture. Monitor patients for signs and symptoms of neurologic impairment. If neurologic compromise is noted, urgent treatment is necessary. Consider the potential benefit versus risk before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis CONTRAINDICATIONS
- Active pathological bleeding
- Severe hypersensitivity reaction to ELIQUIS (apixaban) (e.g., anaphylactic reactions)
- Increased Risk of Stroke with Discontinuation of ELIQUIS in Patients with Nonvalvular Atrial Fibrillation: 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 at least 24 hours after the last dose (i.e., about two half-lives). A specific antidote for ELIQUIS is not available. Hemodialysis does not appear to have a substantial impact on apixaban exposure. 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 have not been studied in patients with prosthetic heart valves and is not recommended in these patients.
TEMPORARY INTERRUPTION 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. Bridging anticoagulation during the 24 to 48 hours after stopping ELIQUIS and prior to the intervention is not generally required. ELIQUIS should be restarted after the surgical or other procedures as soon as adequate hemostasis has been established. 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. For patients receiving 5 mg twice daily, the dose of ELIQUIS should be decreased when it is 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 twice daily, avoid coadministration with strong dual inhibitors of CYP3A4 and P-gp.
- Strong Dual Inducers of CYP3A4 and P-gp: 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 and increase the risk of stroke.
- Anticoagulants and Antiplatelet Agents: Coadministration of antiplatelet agents, fibrinolytics, heparin, aspirin, and chronic NSAID use increases the risk of bleeding. APPRAISE-2, a placebo-controlled clinical trial of apixaban in high-risk post-acute coronary syndrome patients treated with aspirin or the combination of aspirin and clopidogrel, was terminated early due to a higher rate of bleeding with apixaban compared to placebo.
Please see full Prescribing Information, including BOXED WARNINGS and Medication Guide, available at www.bms.com.About DVT and PE Venous thromboembolism, or VTE, encompasses two serious conditions: deep vein thrombosis (DVT) and pulmonary embolism (PE). DVT is a blood clot in a vein, usually in the lower leg, thigh, or pelvis, which partially or totally blocks the flow of blood. PE is a blood clot blocking one or more vessels in the lungs. DVT causes multiple symptoms including pain, swelling, and redness, and more importantly, can progress to PE, which carries the risk of sudden death. Approximately one million patients in the EU are diagnosed every year with VTE.
