Results of the subanalyses at each time interval (7, 21, and 90
days) were consistent with the overall results of the Eliquis
Phase 3 AMPLIFY trial at 6 months and were published in Thrombosis
and Haemostasis
PRINCETON, N.J., & NEW YORK--(BUSINESS WIRE)--
Bristol-Myers
Squibb Company (NYSE:BMY) and Pfizer
Inc. (NYSE:PFE) today announced results from a post-hoc early time
course subanalysis of the Phase 3 AMPLIFY (Apixaban for the Initial
Management of Pulmonary Embolism and Deep Vein Thrombosis as First-Line
Therapy) trial. The subanalysis demonstrated Eliquis (apixaban)
was comparable to conventional therapy (subcutaneous enoxaparin
overlapped and followed by oral warfarin dose-adjusted to an
international normalized ratio of 2.0 to 3.0) in recurrent VTE and
VTE-related death with significantly less major bleeding during the
first 7, 21 and 90 days after starting treatment. These data were
published in Thrombosis and Haemostasis.
“For the millions of patients worldwide who experience VTE, the risks of
recurrence and major bleeding are highest during the first few weeks of
anticoagulant therapy,” said Giancarlo Agnelli, M.D., Professor of
Internal Medicine at the University of Perugia, Italy, Director of the
Department of Internal and Cardiovascular Medicine and Stroke-Unit at
the University Hospital in Perugia, Italy, chair of the AMPLIFY Steering
Committee, and co-author of the publication. “These findings indicate
that the favorable benefit-to-risk profile of Eliquis was
demonstrated early during treatment for VTE, including the use of a
higher Eliquis dose of 10 mg twice daily for the initial seven
days.”
The results of the subanalyses at each pre-specified time interval were
consistent with the overall results of the AMPLIFY trial at 6 months,
which demonstrated non-inferiority of Eliquis versus conventional
therapy in the primary efficacy endpoint of recurrent VTE and
VTE-related death, and superiority in the primary safety endpoint by
showing significantly fewer major bleeding events, with a 69 percent
relative risk reduction (RRR) (absolute risk reduction [ARR] of 1.1
percentage points [95 percent CI, -1.7 to -0.6]) compared to
conventional therapy.
In this post-hoc early time course subanalysis, recurrent VTE and
VTE-related death at 7, 21, and 90 days after starting treatment
occurred in 18 (0.7 percent), 29 (1.1 percent), and 46 (1.8 percent),
patients who were given Eliquis, respectively, and in 23 (0.9
percent), 35 (1.3 percent), and 58 (2.2 percent) patients given
conventional therapy, respectively. Outcomes at each time point were
similar in patients by index event (deep vein thrombosis (DVT) alone or
pulmonary embolism (PE) with or without DVT) and were consistent with
the results for the entire study period. Major bleeding at the
corresponding time points occurred in 3 (0.1 percent), 5 (0.2 percent),
and 11 (0.4 percent) patients, who received Eliquis,
respectively, and in 16 (0.6 percent), 26 (1.0 percent), and 38 (1.4
percent) patients given conventional therapy, respectively. Eliquis
was non-inferior to conventional therapy in recurrent VTE and
VTE-related death at each time point analyzed, with no excess of early
recurrences; and patients treated with Eliquis were less likely
to have major bleeding early in the course of treatment than those
treated with conventional therapy.
The AMPLIFY trial was a double-blind, randomized, multicenter study that
compared the efficacy and safety of Eliquis (at a dose of 10 mg
orally twice daily for seven days, followed by 5 mg orally twice daily
for six months) with those of conventional therapy in 5,395 patients
with symptomatic proximal DVT or symptomatic PE with or without DVT. The
primary efficacy outcome was the incidence of the adjudicated composite
of recurrent symptomatic VTE or death related to VTE that occurred by
the end of the treatment period. The primary safety outcome was
adjudicated major bleeding that occurred by the end of the treatment
period.
For this subanalysis, efficacy and safety outcomes were analyzed for
days 7, 21, and 90 after randomization, substratified for the index
event (DVT alone, or PE with or without DVT).
About Venous Thromboembolism
Venous thromboembolism, or VTE, encompasses two serious conditions: deep
vein thrombosis (DVT), a blood clot in a vein, usually in the lower leg,
thigh or pelvis, which partially or totally blocks the flow of blood;
and pulmonary embolism (PE), a potentially life-threatening condition in
which a blood clot blocks blood vessels in the lungs. Estimates suggest
that the number of adults in the U.S. with VTE is projected to nearly
double from 0.95 million in 2006 to 1.82 million in 2050. Approximately
one million patients in the E.U. are diagnosed with VTE every year. Once
a VTE has occurred, up to 11 percent of people may have a VTE
reoccurrence, which could potentially be fatal.
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 for multiple indications in the U.S. based on efficacy and
safety data from seven Phase 3 clinical trials. Eliquis is a
prescription medicine indicated to reduce the risk of stroke and
systemic embolism in patients with nonvalvular atrial fibrillation
(NVAF); 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; for the treatment of DVT and PE; and to reduce
the risk of recurrent DVT and PE, following initial therapy.
ELIQUIS Important Safety Information and
Indications
|
ELIQUIS 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:
|
-
use of indwelling epidural catheters
|
-
concomitant use of other drugs that affect hemostasis, such
as nonsteroidal anti-inflammatory drugs (NSAIDs), platelet
inhibitors, other anticoagulants
|
-
a history of traumatic or repeated epidural or spinal
punctures
|
-
a history of spinal deformity or spinal surgery
|
-
optimal timing between the administration of ELIQUIS and
neuraxial procedures is not known
|
|
|
|
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.
|
|
|
CONTRAINDICATIONS
-
Active pathological bleeding
-
Severe hypersensitivity reaction to ELIQUIS (e.g., anaphylactic
reactions)
WARNINGS AND PRECAUTIONS
-
Increased Risk of Thrombotic Events after Premature
Discontinuation: Premature discontinuation of any oral
anticoagulant, including 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 atrial fibrillation
patients. If ELIQUIS is discontinued for a reason other than
pathological bleeding or completion of a course of therapy, 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 antiplatelet agents,
other anticoagulants, heparin, thrombolytic agents, SSRIs, SNRIs,
and NSAIDs.
-
Advise patients of signs and symptoms of blood loss and to report
them immediately or go 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.
-
Spinal/Epidural Anesthesia or Puncture: Patients treated with
ELIQUIS undergoing spinal/epidural anesthesia or puncture may develop
an epidural or spinal hematoma which can result in long-term or
permanent paralysis.
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.
-
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.
-
Acute PE in Hemodynamically Unstable Patients or Patients who
Require Thrombolysis or Pulmonary Embolectomy: Initiation of
ELIQUIS is not recommended as an alternative to unfractionated heparin
for the initial treatment of patients with PE who present with
hemodynamic instability or who may receive thrombolysis or pulmonary
embolectomy.
ADVERSE REACTIONS
-
The most common and most serious adverse reactions reported with
ELIQUIS 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.
DRUG INTERACTIONS
-
Strong Dual Inhibitors of CYP3A4 and P-gp: Inhibitors of
cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp) increase
exposure to apixaban and increase the risk of bleeding. For patients
receiving ELIQUIS doses of 5 mg or 10 mg twice daily, reduce the dose
of ELIQUIS by 50% when ELIQUIS 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 2.5 mg twice daily, avoid coadministration of ELIQUIS 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 and other thromboembolic events.
-
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.
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.

Medication Guide, available at www.bms.com.
Indications
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.
