Bristol-Myers
Squibb Company (NYSE:BMY) and Pfizer
Inc. (NYSE:PFE) today announced that the Committee for Medicinal
Products for Human Use (CHMP) of the European Medicines Agency (EMA) has
adopted a positive opinion recommending that Eliquis (apixaban)
be granted marketing authorization for the treatment of DVT (deep vein
thrombosis) and PE (pulmonary embolism), and the prevention of recurrent
DVT and PE, in adults. The CHMP’s positive opinion will now be reviewed
by the European Commission (EC). The decision on whether to approve Eliquis
for this indication will be made by the EC and will be applicable to all
European Union member states plus Iceland and Norway.
The positive opinion was based on the results from the pivotal AMPLIFY
and AMPLIFY-EXT studies. AMPLIFY (Apixaban for the initial Management
of PuLmonary embolIsm and deep vein thrombosis as First-line
therapY), a randomized, double-blind, multicenter trial, included
5,395 patients (2,691 were randomized to Eliquis and 2,704 were
randomized to standard of care, which was initial enoxaparin treatment
overlapped by warfarin therapy) with confirmed symptomatic DVT or PE
requiring treatment for six months, and evaluated Eliquis therapy
compared to standard of care. The primary efficacy endpoint was the
composite endpoint of recurrent symptomatic VTE (nonfatal DVT or
nonfatal PE) or VTE-related death. The primary safety endpoint was the
incidence of major bleeding compared to standard of care.
AMPLIFY-EXT (Apixaban after the initial Management of PuLmonary
embolIsm and deep vein thrombosis with First-line therapY-EXTended
Treatment), a randomized, double-blind, multicenter trial, included
2,486 patients (842 were randomized to Eliquis 2.5 mg, 815 were
randomized to Eliquis 5 mg and 829 were randomized to placebo)
with prior VTE who had completed six to 12 months of anticoagulation
treatment for DVT or PE, and evaluated Eliquis therapy compared
to placebo. The primary efficacy endpoint was reduction of the composite
of symptomatic, recurrent VTE and death from any cause. The primary
safety endpoint was the incidence of major bleeding.

IMPORTANT SAFETY 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)
WARNINGS AND PRECAUTIONS
-
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.
ADVERSE REACTIONS
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.
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.
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), 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 pulmonary embolism (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 US, the number of adults with VTE
is projected to more than double from 0.95 million in 2006 to 1.82
million in 2050. Once a VTE has occurred, up to 10 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 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 the prophylaxis of DVT which can lead to PE 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.
