In the AMPLIFY trial, Eliquis was shown to be non-inferior for the treatment of recurrent venous thromboembolism (VTE)/VTE-related death and was statistically superior in the primary safety endpoint of major bleeding vs. enoxaparin/warfarin
In the AMPLIFY-EXT trial, Eliquis demonstrated a superior reduction in VTE/all-cause death with no statistical difference in major bleeding events vs. placebo
PRINCETON, N.J. & NEW YORK--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE:BMY) and Pfizer Inc. (NYSE:PFE) today announced that the European Commission has approved Eliquis for the treatment of DVT and PE, and the prevention of recurrent DVT and PE in adults. The European Commission approval applies to all European Union (EU) member states as well as Iceland and Norway. Eliquis is also approved in the EU for the prevention of venous thromboembolism (VTE) in adults who have undergone elective total hip or knee replacement surgery, and for the prevention of stroke and systemic embolism in adult patients with nonvalvular atrial fibrillation (NVAF) with one or more risk factors.
“Every year, approximately one million patients in the EU are diagnosed with VTE,” said Dr. Elliott Levy, senior vice president, head of Specialty Development, Bristol-Myers Squibb. “Once a VTE has occurred, approximately 33 percent of patients may experience a recurrence within 10 years.”
The marketing authorization for Eliquis follows the positive opinion issued by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency, and is supported by two pivotal Phase 3 clinical trials, AMPLIFY and AMPLIFY-EXT. AMPLIFY (Apixaban for the initial Management of PuLmonary embolIsm and deep vein thrombosis as First-line therapY) was designed to demonstrate the efficacy and safety of Eliquis for the treatment of DVT and PE versus enoxaparin 1 mg/kg twice daily subcutaneously for at least 5 days (until INR≥ 2) and warfarin (target INR range 2.0-3.0) orally for six months. AMPLIFY-EXT (Apixaban after the initial Management of PuLmonary embolIsm and deep vein thrombosis with First-line therapY-EXTended treatment) was designed to demonstrate the efficacy and safety of Eliquis compared to placebo for the prevention of recurrent DVT and PE following six to 12 months of anticoagulant treatment for DVT and/or PE.
“The European Commission’s approval of Eliquis for the treatment of DVT and PE and the prevention of recurrence is an important milestone and demonstrates Bristol-Myers Squibb and Pfizer’s ongoing commitment to bringing innovative medicines to patients who need them,” said Steve Romano, senior vice president, head of Medicines Development Group for Global Innovative Pharmaceuticals, Pfizer Inc.
About the Clinical Trial Program
As described in the SmPC, in the AMPLIFY study a total of 5,395 patients were randomized to treatment with Eliquis 10 mg twice daily orally for seven days followed by Eliquis 5 mg twice daily orally for six months, or enoxaparin 1 mg/kg twice daily subcutaneously for at least five days (until INR≥ 2) and warfarin (target INR range 2.0-3.0) orally for six months.
The mean age was 56.9 years and 89.8 percent of randomized patients had unprovoked VTE events.
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.
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.
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
WARNINGS AND PRECAUTIONS
The most common and most serious adverse reactions reported with ELIQUIS (apixaban) were related to bleeding.
TEMPORARY INTERRUPTION FOR SURGERY AND OTHER INTERVENTIONS
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 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.
PREGNANCY CATEGORY B
There are no adequate and well-controlled studies of ELIQUIS in pregnant women. Treatment is likely to increase the risk of hemorrhage during pregnancy and delivery. ELIQUIS should be used during pregnancy only if the potential benefit outweighs the potential risk to the mother and fetus.

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.
