Bristol-Myers
Squibb Company (NYSE:BMY) and Pfizer
Inc. (NYSE:PFE) today announced that the first patient has been
enrolled into a Phase IV clinical trial called EMANATE (Eliquis
evaluated in acute cardioversion coMpared to usuAl treatmeNts
for AnTicoagulation in subjEcts with NVAF)
assessing the effectiveness and safety of Eliquis in patients
with nonvalvular atrial fibrillation (NVAF) undergoing cardioversion. Eliquis
is currently approved to reduce the risk of stroke and systemic embolism
in patients with NVAF. Cardioversion (administered through electric
shock to the chest or with medication) is a commonly used, effective
method of converting atrial fibrillation to a normal rhythm, allowing
the heart to pump more effectively. Traditionally, anticoagulation is
administered for a minimum of three weeks prior to cardioversion and for
four weeks afterward. In some patients, early cardioversion can be
performed on the same day or within days of new-onset NVAF, usually
after imaging, to confirm the absence of a pre-existing thrombus in the
heart, which could be dislodged during the cardioversion procedure and
cause a stroke.
EMANATE, a randomized, open-label clinical trial, will assess the
effectiveness and safety of Eliquis compared with usual care
(parenteral heparin and/or oral anticoagulation with a vitamin K
antagonist) initiated in patients with NVAF expected to undergo
cardioversion after short-term anticoagulation, in a clinical practice
setting. In NVAF patients presenting at least 48 hours after the onset
of NVAF, early cardioversion will be performed after excluding a
thrombus by imaging, on the same day or within a few days. In NVAF
patients presenting within 48 hours of the onset of NVAF, cardioversion
will be performed promptly without prior imaging. In all patients, Eliquis
or usual care will be initiated prior to cardioversion and continued for
up to 30 days post-cardioversion.
The EMANATE trial is anticipated to enroll 1,500 eligible patients from
the U.S., Canada, Europe and Asia. Patients will be randomized 1:1 to Eliquis
or usual care, to be administered for up to 30 days following early
cardioversion or 90 days post randomization if cardioversion is not
performed within this timeframe. The primary efficacy endpoints are the
occurrence of acute stroke, systemic embolism and all-cause death.
Primary safety endpoints are major bleeding and clinically relevant
non-major bleeding.
“We are pleased to enroll our first patient in the Phase IV EMANATE
study,” said Jack Lawrence, MD, vice president, Cardiovascular Global
Clinical Research and development lead, Eliquis, Bristol-Myers
Squibb. “This Phase IV trial will provide important data that will
inform the use of Eliquis in patients with NVAF undergoing
cardioversion.”
“Eliquis is approved to reduce the risk of stroke and systemic
embolism in patients with NVAF in a number of countries around the
world, including in the U.S., European Union and Japan,” said Steve
Romano, senior vice president, head of Medicines Development Group for
Global Innovative Pharmaceuticals, Pfizer Inc. “The initiation of the
Phase IV EMANATE study reinforces the long-term commitment of
Bristol-Myers Squibb and Pfizer to understanding and improving health in
patients with NVAF.”
INDICATION
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.
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 Nonvalvular Atrial Fibrillation (NVAF)
Atrial fibrillation is the most common type of irregular heartbeat. It
is estimated that more than 5.8 million Americans and six million
individuals in Europe have atrial fibrillation. One of the most serious
medical concerns for individuals with atrial fibrillation is the
increased risk of stroke, which is five times higher in people with
atrial fibrillation than in people without atrial fibrillation. In North
America and Europe, it is estimated that 98 percent of patients with
atrial fibrillation have NVAF. NVAF is a type of atrial fibrillation
that is not due to rheumatic mitral heart valve disease, a prosthetic
heart valve, or a repairing of the heart’s mitral valve.
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 deep vein thrombosis (DVT) which can
lead to pulmonary embolism (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.
