PRINCETON, N.J. & NEW YORK--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE:BMY) and Pfizer Inc. (NYSE:PFE) today announced results of a pre-specified secondary analysis of the Eliquis Phase 3 AMPLIFY-EXT trial (Apixaban after the initial Management of PuLmonary embolIsm and deep vein thrombosis with First-line therapY-EXTended Treatment). The analysis evaluated clinical and demographic predictors of all-cause hospitalization in patients with VTE, which includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Results from this analysis demonstrated that during the 12-month extended treatment of VTE, Eliquis significantly reduced the risk of hospitalization versus placebo. This effect was independent of other variables including renal function, the only other significant predictor of hospitalization in the AMPLIFY-EXT population. These data were presented during an oral session today in Barcelona, Spain, at the ESC Congress 2014.
“The results of this AMPLIFY-EXT secondary analysis showed that Eliquis significantly reduced the risk of hospitalization, irrespective of other variables,” said Dr. Alexander T. Cohen, study investigator and consultant physician, Department of Hematology, Guy’s and St. Thomas’ Hospitals, King’s College, London. “The findings from this secondary analysis provide additional support for extended anticoagulation with Eliquis in VTE patients.”
AMPLIFY-EXT was a randomized, double-blind, placebo-controlled extended treatment superiority study with 12 months of treatment plus one month follow-up in patients with VTE who completed six to 12 months of anticoagulation therapy. The secondary analysis presented today showed that, compared with placebo, Eliquis 2.5 mg (p=0.032) and 5 mg (p=0.004) were both associated with significant reduction in all-cause hospitalization. Of the 2,486 patients included in the AMPLIFY-EXT trial, 138 patients were hospitalized at least once, including 62 (7.48%) in the placebo group (n=829), 42 (5.00%) in the Eliquis 2.5 mg group (n=840), and 34 (4.18%) in the Eliquis 5 mg group (n=813). Of the first hospitalizations in the placebo group, a total of 32 (51.6%) were attributed to VTE recurrence versus six (17.7%) in the Eliquis 5 mg group and 11 (26.2%) in the Eliquis 2.5 mg group.
The following factors were clinically significant and independent predictors of all-cause hospitalization during the trial:
Sex, age, baseline body weight and type of VTE did not significantly predict hospitalization.
A total of 14 Bristol-Myers Squibb/Pfizer alliance-sponsored abstracts, including the AMPLIFY-EXT pre-specified secondary analysis described above, were accepted for presentation at the ESC Congress 2014.
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 patients with nonvalvular atrial fibrillation in the United States, European Union, Japan and a number of other countries around the world. Eliquis is approved for prevention 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 following initial therapy in the United States and European Union.
ELIQUIS Important Safety Information
ELIQUIS is indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation.
ELIQUIS is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE), in patients who have undergone hip or knee replacement surgery.
ELIQUIS is indicated for the treatment of DVT and PE, and to reduce the risk of recurrent DVT and PE following initial therapy.
Important Safety Information
WARNING: (A) PREMATURE DISCONTINUATION OF ELIQUIS INCREASES THE RISK OF THROMBOTIC EVENTS, (B) SPINAL/EPIDURAL HEMATOMA
(A) Premature discontinuation of any oral anticoagulant, including ELIQUIS, increases the risk of thrombotic events. If anticoagulation with ELIQUIS is discontinued for a reason other than pathological bleeding or completion of a course of therapy, consider coverage with another anticoagulant.
(B) Epidural or spinal hematomas may occur in patients treated with ELIQUIS who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:
Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary.
Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated.
WARNINGS AND PRECAUTIONS
The risk of these events may be increased by the postoperative use of indwelling epidural catheters or the concomitant use of medicinal products affecting hemostasis. Indwelling epidural or intrathecal catheters should not be removed earlier than 24 hours after the last administration of ELIQUIS. The next dose of ELIQUIS should not be administered earlier than 5 hours after the removal of the catheter. The risk may also be increased by traumatic or repeated epidural or spinal puncture. If traumatic puncture occurs, delay the administration of ELIQUIS for 48 hours.
Monitor patients frequently and if neurological compromise is noted, urgent diagnosis and treatment is necessary. Physicians should consider the potential benefit versus the risk of neuraxial intervention in Eliquis patients.

About DVT and PE
VTE encompasses two serious conditions: DVT, a blood clot in a deep vein, usually in the lower leg, thigh, or pelvis, which partially or totally blocks the flow of blood; and PE, a blood clot that blocks one or more vessels in the lungs. Approximately one million patients in the EU are diagnosed every year with VTE. In the U.S., the number of adults with VTE is projected to more than double from 950,000 in 2006 to 1.82 million in 2050. Once a VTE has occurred, approximately 33% of patients may experience a recurrence within 10 years.
