Methods for Treating Patients with Hyperlipidemia by Administering
a PCSK9 Inhibitor in Combination with an ANGPTL3 Inhibitor
Abstract
The present invention provides methods for treating patients
suffering from hypercholesterolemia, wherein the patient is
non-responsive to, inadequately controlled by, or intolerant to
treatment with a standard lipid modifying therapy. The methods of
the invention provide for lowering at least one lipid parameter in
the patient by administering a therapeutically effective amount of
an antibody or antigen-binding fragment thereof that specifically
binds to proprotein convertase subtilisin/kexin type 9 (PCSK9) in
combination with a therapeutically effective amount of an antibody
that specifically binds to angiopoietin-like protein 3 (ANGPTL3).
The combination of an anti-PCSK9 antibody with an anti-ANGPTL3
antibody is useful in treating diseases such as
hypercholesterolemia, including familial hypercholesterolemia (FH),
both heFH and hoFH, as well as hyperlipidemia, hyperlipoproteinemia
and dyslipidemia, including hypertriglyceridemia, chylomicronemia,
and to prevent or treat diseases or disorders, for which abnormal
lipid metabolism is a risk factor, such as cardiovascular
diseases.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit under 35 U.S.C.
.sctn.119(e) of US provisional application No. 62/302,907, filed on
Mar. 3, 2016. The disclosure of the aforementioned patent
application is herein incorporated by reference in its
entirety.
FIELD OF THE INVENTION
[0002] The present invention relates to the field of therapeutic
treatments of diseases and disorders, which are associated with
elevated levels of lipids and lipoproteins. More specifically, the
invention relates to the use of a proprotein convertase
subtilisin/kexin type 9 (PCSK9) inhibitor in combination with an
inhibitor of angiopoietin-like protein 3 (ANGPTL3) to treat
patients with hypercholesterolemia and related conditions, who are
non-responsive to, inadequately controlled by, or intolerant to
treatment with a standard lipid modifying therapy.
BACKGROUND
[0003] Hyperlipidemia is a general term that encompasses diseases
and disorders characterized by or associated with elevated levels
of lipids and/or lipoproteins in the blood. Hyperlipidemias include
hypercholesterolemia, hypertriglyceridemia, combined
hyperlipidemia, and elevated lipoprotein a (Lp(a)). A particular
prevalent form of hyperlipidemia in many populations is
hypercholesterolemia.
[0004] Hypercholesterolemia, particularly an increase in
low-density lipoprotein (LDL) cholesterol (LDL-C) levels,
constitutes a major risk for the development of atherosclerosis and
coronary heart disease (CHD) (Sharrett et al., 2001, Circulation
104:1108-1113). Low-density lipoprotein cholesterol is identified
as the primary target of cholesterol lowering therapy and is
accepted as a valid surrogate therapeutic endpoint. Numerous
studies have demonstrated that reducing LDL-C levels reduces the
risk of CHD with a strong direct relationship between LDL-C levels
and CHD events; for each 1 mmol/L (.about.40 mg/dL) reduction in
LDL-C, cardiovascular disease (CVD) mortality and morbidity is
lowered by 22%. Greater reductions in LDL-C produce greater
reduction in events, and comparative data of intensive versus
standard statin treatment suggest that the lower the LDL-C level,
the greater the benefit in patients at very high cardiovascular
(CV) risk.
[0005] Familial hypercholesterolemia (FH) is an inherited disorder
of lipid metabolism that predisposes a person to premature severe
cardiovascular disease (CVD) (Kolansky et al., (2008), Am J
Cardiology,102(11):1438-1443). FH can be either an autosomal
dominant or an autosomal recessive disease that results from
mutations in the low density lipoprotein receptor (LDLR), or in at
least 3 different genes that code for proteins involved in hepatic
clearance of LDL-C can cause FH. Examples of such defects include
mutations in the gene coding for the LDL receptor (LDLR) that
removes LDL-C from the circulation, and in the gene for
apolipoprotein (Apo) B, which is the major protein of the LDL
particle. In certain cases of FH, the gene coding for proprotein
convertase subtilisin/kexin type 9 (PCSK9), an enzyme involved in
degrading the LDLR (gain of function mutation), is mutated. In all
cases, FH is characterized by an accumulation of LDL-C in the
plasma from birth and subsequent development of tendon xanthomas,
xanthelasmas, atheromata, and CVD. FH can be classified as either
heterozygous FH (heFH) or homozygous FH (hoFH) depending on whether
the individual has a genetic defect in one (heterozygous) or both
(homozygous) copies of the implicated gene.
[0006] Current LDL-C-lowering medications include statins,
cholesterol absorption inhibitors, fibrates, niacin, and bile acid
sequestrants. Statins are a commonly prescribed treatment for LDL-C
lowering. However, despite the availability of such lipid-lowering
therapies, many high-risk patients fail to reach their guideline
target LDL-C level (Gitt et al., 2010, Clin Res Cardiol
99(11):723-733). For patients who are still unable to achieve
guideline target level for LDL-C, despite available lipid-modifying
therapy (LMT), mechanical removal of LDL-C by lipoprotein apheresis
(e.g., LDL apheresis) is sometimes prescribed.
[0007] However, patients who are not at LDL-C goal despite
receiving an optimized LMT regiment, would greatly benefit from
alternative LDL-C lowering therapies, or through use of a
combination of therapeutic agents, such as the agents and regimens
described herein.
BRIEF SUMMARY OF THE INVENTION
[0008] The present invention provides methods for treating
hyperlipidemia in patients who are non-responsive to, inadequately
controlled by, or intolerant to treatment with a standard lipid
modifying therapy. The therapeutic methods of the present invention
result in a lowering of serum lipoprotein levels to a normal and
acceptable range and as such, may act to reduce the risk of
development of atherosclerosis, or coronary heart disease.
[0009] In one aspect, the invention provides a method of treating a
patient suffering from hypercholesterolemia, wherein the patient is
non-responsive to, inadequately controlled by, or intolerant to
treatment with a standard lipid modifying therapy, the method
comprising treating the patient with a combination of a proprotein
convertase subtilisin/kexin type 9 (PCSK9) inhibitor and an
inhibitor of angiopoietin-like protein 3 (ANGPTL3).
[0010] In one embodiment, the invention provides administering one
or more doses of a PCSK9 inhibitor in combination with one or more
doses of an ANGPTL3 inhibitor to a patient who is being treated, or
has been treated with a standard lipid modifying therapy, but has
not responded to such therapy. Administration of a combination of a
PCSK9 inhibitor with an ANGPTL3 inhibitor to the patient results in
lowering the level of at least one lipoprotein in the serum of the
patient and consequently reduces or eliminates the need for
treatment with the standard lipid lowering therapy by the
patient.
[0011] In a related aspect, the methods of the present invention
comprise selecting a patient with hypercholesterolemia who is being
treated, or has been treated with a standard lipid lowering therapy
and who is non-responsive to, inadequately controlled by, or
intolerant to, such therapy and administering one or more doses of
a PCSK9 antibody in combination with one or more doses of an
ANGPTL3 antibody to the patient, thereby lowering the level of at
least one lipoprotein in the serum of the patient and consequently
replacing the use of the standard lipid modifying therapy with the
combination therapy of a PCSK9 antibody plus an ANGPTL3 antibody to
achieve a target lipoprotein level.
[0012] Patients who are treated or treatable by the methods of the
present invention include, e.g., patients with
hypercholesterolemia, including patients with familial
hypercholesterolemia (FH). In certain embodiments, the patients who
are treated or treatable by the methods of the present invention
are patients who are diagnosed with (or otherwise known to have),
homozygous FH (hoFH) or heterozygous FH (heFH), or at risk for
developing abnormally high lipid and/or lipoprotein levels
associated with homozygous FH (hoFH) or heterozygous FH (heFH).
[0013] The present invention also provides pharmaceutical
compositions comprising a PCSK9 inhibitor and an ANGPTL3 inhibitor
for use in treating a patient who is non-responsive to,
inadequately controlled by, or intolerant to treatment with a
standard lipid modifying therapy, such as a statin. The statin may
be selected from the group consisting of atorvastatin (LIPITOR6),
pitavastatin (LIVALO.RTM.), lovastatin (MEVACOR6), simvastatin
(ZOCOR6), pravastatin (PRAVACHOL.RTM.) fluvastatin (LESCOL.RTM.)
and rosuvastatin (CRESTOR.RTM.). Other standard lipid lowering
agents that may be used in patients suffering from
hypercholesterolemia, include, but are not limited to, fibrates,
niacin, bile acid sequestrants, ezetimibe (ZETIA.RTM.), lomitapide
(JUZTAPIDTM), phytosterols, orlistat (XENICAL.RTM.).
[0014] Exemplary PCSK9 inhibitors, or ANGPTL3 inhibitors that may
be used in the context of the methods of the present invention
include, e.g., anti-PCSK9 or anti-ANGPTL3 antibodies, small
molecule inhibitors, and scaffold-based, i.e. PCSK9-binding
molecules, or ANGPTL3-binding molecules.
[0015] In certain embodiments, it is envisioned that the use of the
combination of the PCSK9 inhibitor with the ANGPTL3 inhibitor may
be sufficiently effective at lowering serum lipid and/or
lipoprotein levels, such that the dose of the standard lipid
modifying therapy may be reduced to eliminate any untoward effects,
or it may be eliminated altogether.
[0016] In one embodiment, the methods provide for treating a
patient in need thereof with an antibody, or an antigen-binding
fragment thereof, that binds specifically to PCSK9 in combination

Methods for Treating Hyperlipidemias
[0048] The present invention relates generally to methods and
compositions for reducing lipoprotein levels in patients suffering
from hypercholesterolemia, who are non-responsive to, inadequately
controlled by, or intolerant to standard lipid modifying therapies
(e.g. a statin). In certain embodiments of the invention, treatment
with a PCSK9 inhibitor in combination with an ANGPTL3 inhibitor may
serve to lower the levels of lipoproteins in these patients to an
acceptable range, thereby lowering their risk for development of
atherosclerosis, stroke and other cardiovascular diseases. In
certain embodiments, the methods described may be used to treat
patients suffering from hypercholesterolemia, including
heterozygous familial hypercholesterolemia (heFH) and/or homozygous
familial hypercholesterolemia (hoFH), in the event that these
patients are non-responsive to, inadequately controlled by, or
intolerant to standard lipid modifying therapies.
[0049] As used herein, the term "lipoprotein" means a biomolecular
particle containing both protein and lipid. Examples of
lipoproteins include, e.g., low density lipoprotein (LDL),
high-density lipoprotein (HDL), very low density lipoprotein
(VLDL), intermediate density lipoprotein (IDL), and lipoprotein (a)
(Lp(a)).
[0050] The present invention, according to certain embodiments,
includes methods for treating patients who are non-responsive to,
inadequately controlled by, or intolerant to standard lipid
modifying therapy. As used herein, a particular patient who is
"non-responsive to, inadequately controlled by, or intolerant to,
standard lipid modifying therapy" is determined by a physician,
physician's assistant, diagnostician, or other medical professional
on the basis of the level of one or more lipoproteins (e.g., LDL-C
and/or non-HDL-C) measured or otherwise detected in the serum of
the patient after treatment with the standard lipid modifying
agent. The physician, physician's assistant, diagnostician, or
other medical professional can also determine if the patient is
intolerant to standard lipid modifying therapies based on the side
effect profile of the standard lipid modifying therapies, which the
patient may experience, including, but not limited to, muscle
aches, tenderness or weakness (myalgia), headache, skin flushing,
difficulty sleeping, abdominal cramping, bloating, diarrhea,
constipation, rash, nausea, or vomiting. A patient who is
non-responsive to, inadequately controlled by, or intolerant to
standard lipid modifying therapy may also be determined or
influenced by other factors such as the patient's family history,
medical background, current therapeutic treatment status, as well
as generally accepted or prevailing lipoprotein targets adopted by
national medical associations and physicians' groups. For example,
in certain contexts, if a patient is undergoing therapy with a
standard lipid modifying agent, and exhibits an LDL-C level of
greater than or equal to about 70 mg/dL, this indicates that the
patient is "non-responsive to, or inadequately controlled by, or
intolerant to standard lipid modifying therapy" and may benefit by
treatment using the therapies described herein. In other contexts,
if a patient is undergoing therapy with a standard lipid modifying
agent, and exhibits an LDL-C level of greater than or equal to
about 100 mg/dL, this indicates that the patient is "non-responsive
to, inadequately controlled by, or intolerant to standard lipid
modifying therapy" and may benefit by treatment using the therapies
described herein. In certain contexts, if a patient is undergoing
therapy with a standard lipid modifying agent, and exhibits an
LDL-C level of greater than or equal to about 150 mg/dL, 200 mg/dL,
250 mg/dL, 300 mg/dL, 400 mg/dL or higher, this indicates that the
patient is "non-responsive to, inadequately controlled by, or
intolerant to standard lipid modifying therapy" and may benefit by
treatment using the therapies described herein. In yet other
contexts, whether or not a particular percentage reduction in LDL-C
or non-HDL-C level is met, relative to the patient's LDL-C or
non-HDL-C level at a particular start point ("baseline") can be
used to determine whether the patient has responded to standard
lipid modifying therapy or whether that patient is in need of
further treatment using the methods and agents of the present
invention. For instance, a reduction in LDL-C or non-HDL-C of less
than 50% (e.g., less than 40%, less than 35%, less than 30%, less
than 25%, etc.) from baseline may signify a need for therapy using
the methods and agents of the invention.
[0051] The present invention, accordingly, includes methods of
treatment comprising administration of one or more doses of a PCSK9
inhibitor combined with one or more doses of an ANGPTL3 inhibitor
to a patient, whereby the patient's post-treatment levels of total
cholesterol, LDL-C, and/or non-HDL-C are significantly reduced in
numbers. For example, the present invention includes therapeutic
methods comprising administering one or more doses of a PCSK9
inhibitor and one or more doses of an ANGPTL3 inhibitor to a
patient who is undergoing standard lipid modifying therapy, but is
non-responsive to such therapy, or is intolerant to such therapy,
wherein, after receiving one or more doses of the PCSK9 inhibitor
and one or more doses of the ANGPTL3 inhibitor, the patient is able
to achieve normal levels of total cholesterol, LDL-C, or non-LDL-C.
In certain instances, the patient may be taken off of the standard
lipid modifying therapy, or the standard lipid modifying therapy
may be continued, but may be administered at lower doses and may be
used in combination with the PCSK9 inhibitor and the ANGPTL3
inhibitor, to achieve and/or maintain a particular target
lipoprotein level. Alternatively, the patient may be administered
the standard lipid modifying therapy at the normal prescribed dose,
but the frequency of administration of the lipid modifying therapy
may be reduced if the standard lipid modifying therapy is to be
administered in conjunction with the combination of the PCSK9
inhibitor and the ANGPTL3 inhibitor. In some instances, the need
for treatment with the standard lipid modifying therapy by the
patient to achieve and/or maintain a particular target lipoprotein
level may be eliminated altogether following administration of one
or more doses of the PCSK9 inhibitor in conjunction with the
ANGPTL3 inhibitor.
[0052] According to certain embodiments, the present invention
comprises methods for reducing or eliminating the need for standard
lipid modifying therapy, wherein the methods comprise selecting a
patient with hyperlipidemia (e.g., hypercholesterolemia) who has
been treated with lipid modifying therapy within the last month,
the last 2 months, the last 3 months, the last 4 months, the last 5
months, the last 6 months, or for a longer period, and
administering one or more doses of a PCSK9 inhibitor in combination
with an ANGPTL3 inhibitor to the patient. The methods according to
this aspect of the invention result in lowering the level of at
least one lipoprotein in the serum of the patient, and consequently
allow for a reduction or elimination of the need for treatment with
the standard lipid modifying therapy by the patient. For example,
in certain embodiments of the present invention, following
administration of one or more doses of a PCSK9 inhibitor in
combination with an ANGPTL3 inhibitor, the serum LDL-C level of the
patient is reduced to less than a defined level (e.g., less than
100 mg/dL or less than 70 mg/dL), or the total cholesterol is
lowered to a defined level (e.g. less than 200 mg/dL, or less than
150 mg/dL.
[0053] According to certain embodiments, the patient who is
treatable by the methods of the present invention has
hypercholesterolemia (e.g., a serum LDL-C concentration of greater
than or equal to 70 mg/dL, or a serum LDL-C concentration greater
than or equal to 100 mg/dL). In certain embodiments, the patient's
hypercholesterolemia is inadequately controlled by standard lipid
modifying therapy, e.g. statin therapy. For example, the present
invention includes methods for treating a patient who is
non-responsive, inadequately controlled by, or intolerant to,
therapy with a standard lipid modifying therapy, such as a statin,
or who has hypercholesterolemia that is inadequately controlled by
a daily dose of a statin selected form the group consisting of
atorvastatin (including atorvastatin+ezetimibe), rosuvastatin,
cerivastatin, pitavastatin, fluvastatin, lovastatin, simvastatin
(including simvastatin+ezetimibe), pravastatin, and combinations
thereof. The present invention also includes methods for reducing
cholesterol, LDL-C, or non-LDL-C in a patient who has
hypercholesterolemia and who exhibits statin intolerance or who
otherwise experiences adverse or undesirable reaction(s) to statin
therapy (e.g., skeletal muscle pain, aches, weakness or cramping
[e.g., myalgia, myopathy, rhabdomyolysis, etc.]).
Patient Selection
[0054] The present invention includes methods and compositions
useful for treating patients who are suffering from hyperlipidemia,
who are non-responsive to, inadequately controlled by, or
intolerant to, therapy with a standard lipid modifying therapy. The
patients who are treatable by the methods of the present invention
may also exhibit one or more of additional selection criteria. For
example, a patient may be selected for treatment with the methods
of the present invention if the patient is diagnosed with or
identified as being at risk of developing a hypercholesterolemia
condition such as, e.g., heterozygous Familial Hypercholesterolemia
(heFH), homozygous Familial Hypercholesterolemia (hoFH), Autosomal
Dominant Hypercholesterolemia (ADH, e.g., ADH associated with one
or more gain-of-function mutations in the PCSK9 gene), autosomal
recessive hypercholesterolemia (ARH, e.g., ARH associated with
mutations in LDLRAP1), as well as incidences of
hypercholesterolemia that are distinct from Familial
Hypercholesterolemia (nonFH). Diagnosis of familial
hypercholesterolemia (e.g., heFH or hoFH) can be made by genotyping
and/or clinical criteria. For patients who are not genotyped,
clinical diagnosis may be based on either the Simon Broome criteria
with a criteria for definite FH, or the WHO/Dutch Lipid Network
criteria with a score>8 points.
[0055] According to certain embodiments, the patient may be
selected on the basis of having a history of coronary heart disease
(CHD). As used herein a "history of CHD" (or "documented history of
CHD") includes one or more of: (i) acute myocardial infarction
(MI); (ii) silent MI; (iii) unstable angina; (iv) coronary
revascularization procedure (e.g., percutaneous coronary
intervention [PCI] or coronary artery bypass graft surgery [CABG]);
and/or (v) clinically significant CHD diagnosed by invasive or
non-invasive testing (such as coronary angiography, stress test
using treadmill, stress echocardiography or nuclear imaging).
[0056] According to certain embodiments, the patient may be
selected on the basis of having non-coronary heart disease
cardiovascular disease ("non-CHD CVD"). As used herein, "non-CHD
CVD" includes one or more of: (i) documented previous ischemic
stroke with a focal ischemic neurological deficit that persisted
more than 24 hours, considered as being of atherothrombotic origin;
(ii) peripheral arterial disease; (iii) abdominal aortic aneurysm;
(iv) atherosclerotic renal artery stenosis; and/or (v) carotid
artery disease (transient ischemic attacks or >50% obstruction
of a carotid artery).
[0057] According to certain embodiments, the patient may be
selected on the basis of having one or more additional risk factors
such as, e.g., (i) documented moderate chronic kidney disease (CKD)
as defined by 30 eGFR <60 mL/min/1.73 m2 for 3 months or more;
(ii) type 1 or type 2 diabetes mellitus with or without target
organ damage (e.g., retinopathy, nephropathy, microalbuminuria);
(iii) a calculated 10-year fatal CVD risk SCORE .gtoreq.5% (ESC/EAS
Guidelines for the management of dyslipidemias, Conroy et al.,
2003, Eur. Heart J. 24:987-1003).
[0058] According to certain embodiments, the patient may be
selected on the basis of having one or more additional risk factors
selected from the group consisting of age (e.g., older than 40, 45,
50, 55, 60, 65, 70, 75, or 80 years), race, national origin, gender
(male or female), exercise habits (e.g., regular exerciser,
non-exerciser), other preexisting medical conditions (e.g., type-II
diabetes, high blood pressure, etc.), and current medication status
(e.g., currently taking beta blockers, niacin, ezetimibe, fibrates,
omega-3 fatty acids, bile acid resins, etc.).
[0059] According to certain embodiments of the present invention,
the subject who is treatable by the methods of the invention
exhibits an elevated level of one or more inflammatory marker. Any
marker of systemic inflammation can be utilized for the purposes of
the present invention. Suitable inflammatory markers include,
without limitation, C-reactive protein, cytokines (e.g., II-6,
IL-8, and/or IL-17), and cellular adhesion molecules (e.g., ICAM-1,
ICAM-3, BL-CAM, LFA-2, VCAM-1, NCAM, and PECAM).
[0060] According to the present invention, patients may be selected
on the basis of a combination of one or more of the foregoing
selection criteria or therapeutic characteristics. For example,
according to certain embodiments, a patient suitable for treatment
with the methods of the present invention, may further be selected
on the basis of having heFH or non-FH in combination with: (i) a
history of documented CHD, (ii) non-CHD CVD, and/or (iii) diabetes
mellitus with target organ damage; such patients may also be
selected on the basis of having a serum LDL-C concentration of
greater than or equal to 70 mg/dL.
[0061] According to certain other embodiments, a patient suitable
for treatment with the methods of the present invention, in
addition to having hypercholesterolemia that is not adequately
controlled by a daily moderate-dose therapeutic statin regimen, may
further be selected on the basis of having heFH or non-FH without
CHD, or non-CHD CVD, but having either (i) a calculated 10-year
fatal CVD risk SCORE .gtoreq.5% or (ii) diabetes mellitus without
target organ damage; such patients may also be selected on the
basis of having a serum LDL-C concentration of greater than or
equal to 100 mg/dL.
[0062] According to certain embodiments of the present invention,
the subject who is treatable by the methods of the invention is a
subject who has familial chylomicronemia syndrome (FCS; also known
as lipoprotein lipase deficiency).
[0063] According to certain embodiments of the present invention,
the subject who is treatable by the methods of the invention is a
subject who is undergoing, or has recently undergone, lipoprotein
apheresis (e.g., within the last six months, within the last 12
weeks, within the last 8 weeks, within the last 6 weeks, within the
last 4 weeks, within the last 2 weeks, etc.).
Administration of a PCSK9 Inhibitor plus an ANGPTL3 Inhibitor as
Add-On Therapy
[0064] The present invention includes methods of treatment wherein
a patient who is undergoing, or has recently undergone, standard
lipid modifying therapy (e.g. a statin) is administered a PCSK9
inhibitor plus an ANGPTL3 inhibitor according to a particular
dosing amount and frequency, and wherein the PCSK9 inhibitor and
the ANGPTL3 inhibitor are administered as an add-on to the
patient's pre-existing lipid modifying therapy (if applicable),
such as an add-on to the patient's pre-existing daily therapeutic
statin regimen.
[0065] For example, the methods of the present invention include
add-on therapeutic regimens wherein the PCSK9 inhibitor and the
ANGPTL3 inhibitor are administered as add-on therapy to the same
stable daily therapeutic statin regimen (i.e., same dosing amount
of statin) that the patient was on prior to receiving the PCSK9 and
ANGPTL3 inhibitors. In other embodiments, the PCSK9 and ANGPTL3
inhibitors are administered as add-on therapy to a therapeutic
statin regimen comprising a statin in an amount that is more than
or less than the dose of statin the patient was on prior to
receiving the PCSK9 and ANGPTL3 inhibitors. For example, after
starting a therapeutic regimen comprising a PCSK9 inhibitor and an
ANGPTL3 inhibitor administered at particular dosing frequencies and
amounts, the daily dose of statin administered or prescribed to the
patient may (a) stay the same, (b) increase, or (c) decrease (e.g.,
up-titrate or down-titrate) in comparison to the daily statin dose
the patient was taking before starting the PCSK9 and ANGPTL3
inhibitors therapeutic regimen, depending on the therapeutic needs
of the patient.
Therapeutic Efficacy
[0066] The methods of the present invention may result in the
reduction in serum levels of one or more lipid components selected
from the group consisting of total cholesterol, LDL-C, non-HDL-C,
ApoB100, VLDL-C, triglycerides, Lp(a) and remnant cholesterol. For
example, according to certain embodiments of the present invention,
administration of a PCSK9 inhibitor in combination with an ANGPTL3
inhibitor to a suitable subject will result in a mean percent
reduction from baseline in serum low density lipoprotein
cholesterol (LDL-C) of at least about 25%, 30%, 40%, 50%, 60%, or
greater; a mean percent reduction from baseline in ApoB100 of at
least about 25%, 30%, 40%, 50%, 60%, or greater; a mean percent
reduction from baseline in non-HDL-C of at least about 25%, 30%,
40%, 50%, 60%, or greater; a mean percent reduction from baseline
in total cholesterol of at least about 10%, 15%, 20%, 25%, 30%,
35%, or greater; a mean percent reduction from baseline in VLDL-C
of at least about 5%, 10%, 15%, 20%, 25%, 30%, or greater; a mean
percent reduction from baseline in triglycerides of at least about
5%, 10%, 15%, 20%, 25%, 30%, 35% or greater; and/or a mean percent
reduction from baseline in Lp(a) of at least about 5%, 10%, 15%,
20%, 25%, or greater.
PCSK9 Inhibitors and ANGPTL3 Inhibitors
[0067] The methods of the present invention comprise administering
to a patient a therapeutic composition comprising a PCSK9 inhibitor
and an ANGPTL3 inhibitor.
PCSK9 Inhibitors
[0068] As used herein, a "PCSK9 inhibitor" is any agent, which
binds to or interacts with human PCSK9 and inhibits the normal
biological function of PCSK9 in vitro or in vivo. Non-limiting
examples of categories of PCSK9 inhibitors include small molecule
PCSK9 antagonists, nucleic acid-based inhibitors of PCSK9
expression or activity (e.g., siRNA or antisense), peptide-based
molecules that specifically interact with PCSK9 (e.g.,
peptibodies), receptor molecules that specifically interact with
PCSK9, proteins comprising a ligand-binding portion of an LDL
receptor, PCSK9-binding scaffold molecules (e.g., DARPins, HEAT
repeat proteins, ARM repeat proteins, tetratricopeptide repeat
proteins, fibronectin-based scaffold constructs, and other
scaffolds based on naturally occurring repeat proteins, etc., [see,
e.g., Boersma and Pluckthun, 2011, Curr. Opin. Biotechnol.
22:849-857, and references cited therein]), and anti-PCSK9 aptamers
or portions thereof. According to certain embodiments, PCSK9
inhibitors that can be used in the context of the present invention
are anti-PCSK9 antibodies or antigen-binding fragments of
antibodies that specifically bind human PCSK9.
[0069] The term "human proprotein convertase subtilisin/kexin type
9" or "human PCSK9" or "hPCSK9", as used herein, refers to PCSK9
having the nucleic acid sequence shown in SEQ ID NO:22 and the
amino acid sequence of SEQ ID NO:23, or a biologically active
fragment thereof.
ANGPTL3 Inhibitors
[0070] As used herein, an " ANGPTL3 inhibitor" is any agent, which
binds to or interacts with human ANGPTL3 and inhibits the normal
biological function of ANGPTL3 in vitro or in vivo. Non-limiting
examples of categories of ANGPTL3 inhibitors include small molecule
ANGPTL3 antagonists, nucleic acid-based inhibitors of ANGPTL3
expression or activity (e.g., siRNA or antisense), peptide-based
molecules that specifically interact with ANGPTL3 (e.g.,
peptibodies), receptor molecules that specifically interact with
ANGPTL3, ANGPTL3-binding scaffold molecules (e.g., DARPins, HEAT
repeat proteins, ARM repeat proteins, tetratricopeptide repeat
proteins, fibronectin-based scaffold constructs, and other
scaffolds based on naturally occurring repeat proteins, etc., [see,
e.g., Boersma and Pluckthun, 2011, Curr. Opin. Biotechnol.
22:849-857, and references cited therein]), and anti-ANGPTL3
aptamers or portions thereof. According to certain embodiments,
ANGPTL3 inhibitors that can be used in the context of the present
invention are anti-ANGPTL3 antibodies or antigen-binding fragments
of antibodies that specifically bind human ANGPTL3.
[0071] The term "human angiopoietin-like protein-3" or "human
ANGPTL3" or "hANGPTL3", as used herein, refers to ANGPTL3 having
the amino acid sequence of SEQ ID NO: 1 (see also NCBI Accession
NP_055310), or a biologically active fragment thereof.
[0072] The term "antibody", as used herein, is intended to refer to
immunoglobulin molecules comprising four polypeptide chains, two
heavy (H) chains and two light (L) chains inter-connected by
disulfide bonds, as well as multimers thereof (e.g., IgM). Each
heavy chain comprises a heavy chain variable region (abbreviated
herein as HCVR or V.sub.H) and a heavy chain constant region. The
heavy chain constant region comprises three domains, C.sub.H1,
C.sub.H2 and C.sub.H3. Each light chain comprises a light chain
variable region (abbreviated herein as LCVR or V.sub.L) and a light
chain constant region. The light chain constant region comprises
one domain (C.sub.L1). The V.sub.H and V.sub.L regions can be
further subdivided into regions of hypervariability, termed
complementarity determining regions (CDRs), interspersed with
regions that are more conserved, termed framework regions (FR).
Each V.sub.H and V.sub.L is composed of three CDRs and four FRs,
arranged from amino-terminus to carboxy-terminus in the following
order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. In different
embodiments of the invention, the FRs of the anti-PCSK9 antibody
(or antigen-binding portion thereof) may be identical to the human
germline sequences, or may be naturally or artificially modified.
An amino acid consensus sequence may be defined based on a
side-by-side analysis of two or more CDRs.
[0073] The term "antibody," as used herein, also includes
antigen-binding fragments of full antibody molecules. The terms
"antigen-binding portion" of an antibody, "antigen-binding
fragment" of an antibody, and the like, as used herein, include any
naturally occurring, enzymatically obtainable, synthetic, or
genetically engineered polypeptide or glycoprotein that
specifically binds an antigen to form a complex. Antigen-binding
fragments of an antibody may be derived, e.g., from full antibody
molecules using any suitable standard techniques such as
proteolytic digestion or recombinant genetic engineering techniques
involving the manipulation and expression of DNA encoding antibody
variable and optionally constant domains. Such DNA is known and/or
is readily available from, e.g., commercial sources, DNA libraries
(including, e.g., phage-antibody libraries), or can be synthesized.
The DNA may be sequenced and manipulated chemically or by using
molecular biology techniques, for example, to arrange one or more
variable and/or constant domains into a suitable configuration, or
to introduce codons, create cysteine residues, modify, add or
delete amino acids, etc.
[0074] Non-limiting examples of antigen-binding fragments include:
(i) Fab fragments; (ii) F(ab')2 fragments; (iii) Fd fragments; (iv)
Fv fragments; (v) single-chain Fv (scFv) molecules; (vi) dAb
fragments; and (vii) minimal recognition units consisting of the
amino acid residues that mimic the hypervariable region of an
antibody (e.g., an isolated complementarity determining region
(CDR) such as a CDR3 peptide), or a constrained FR3-CDR3-FR4
peptide. Other engineered molecules, such as domain-specific
antibodies, single domain antibodies, domain-deleted antibodies,
chimeric antibodies, CDR-grafted antibodies, diabodies, triabodies,
tetrabodies, minibodies, nanobodies (e.g. monovalent nanobodies,
bivalent nanobodies, etc.), small modular immunopharmaceuticals
(SMIPs), and shark variable IgNAR domains, are also encompassed
within the expression "antigen-binding fragment," as used
herein.
[0075] An antigen-binding fragment of an antibody will typically
comprise at least one variable domain. The variable domain may be
of any size or amino acid composition and will generally comprise
at least one CDR, which is adjacent to or in frame with one or more
framework sequences. In antigen-binding fragments having a V.sub.H
domain associated with a V.sub.L domain, the V.sub.H and V.sub.L
domains may be situated relative to one another in any suitable
arrangement. For example, the variable region may be dimeric and
contain V.sub.H-V.sub.H, V.sub.H-V.sub.L or V.sub.L-V.sub.L dimers.
Alternatively, the antigen-binding fragment of an antibody may
contain a monomeric V.sub.H or V.sub.L domain.
[0076] In certain embodiments, an antigen-binding fragment of an
antibody may contain at least one variable domain covalently linked
to at least one constant domain. Non-limiting, exemplary
configurations of variable and constant domains that may be found
within an antigen-binding fragment of an antibody of the present
invention include: (i) V.sub.H-C.sub.H1; (ii) V.sub.H-C.sub.H2;
(iii) V.sub.H-C.sub.H3; (iv) V.sub.H-C.sub.H1-C.sub.H2; (v)
V.sub.H-C.sub.H1-C.sub.H2-C.sub.H3; (vi) V.sub.H-C.sub.H2-C.sub.H3;
(vii) V.sub.H-C.sub.L; (viii) V.sub.L-C.sub.H1; (ix)
V.sub.L-C.sub.H2; (x) V.sub.L-C.sub.H3; (xi)
V.sub.L-C.sub.H1-C.sub.H2; (xii)
V.sub.L-C.sub.H1-C.sub.H2-C.sub.H3; (xiii)
V.sub.L-C.sub.H2-C.sub.H3; and (xiv) V.sub.L-C.sub.L. In any
configuration of variable and constant domains, including any of
the exemplary configurations listed above, the variable and
constant domains may be either directly linked to one another or
may be linked by a full or partial hinge or linker region. A hinge
region may consist of at least 2 (e.g., 5, 10, 15, 20, 40, 60 or
more) amino acids, which result in a flexible or semi-flexible
linkage between adjacent variable and/or constant domains in a
single polypeptide molecule. Moreover, an antigen-binding fragment
of an antibody of the present invention may comprise a homo-dimer
or hetero-dimer (or other multimer) of any of the variable and
constant domain configurations listed above in non-covalent
association with one another and/or with one or more monomeric
V.sub.H or V.sub.L domain (e.g., by disulfide bond(s)).
[0077] As with full antibody molecules, antigen-binding fragments
may be monospecific or multispecific (e.g., bispecific). A
multispecific antigen-binding fragment of an antibody will
typically comprise at least two different variable domains, wherein
each variable domain is capable of specifically binding to a
separate antigen or to a different epitope on the same antigen. Any
multispecific antibody format, including the exemplary bispecific
antibody formats disclosed herein, may be adapted for use in the
context of an antigen-binding fragment of an antibody of the
present invention using routine techniques available in the
art.
[0078] The constant region of an antibody is important in the
ability of an antibody to fix complement and mediate cell-dependent
cytotoxicity. Thus, the isotype of an antibody may be selected on
the basis of whether it is desirable for the antibody to mediate
cytotoxicity.
[0079] The term "human antibody", as used herein, is intended to
include antibodies having variable and constant regions derived
from human germline immunoglobulin sequences. The human antibodies
of the invention may nonetheless include amino acid residues not
encoded by human germline immunoglobulin sequences (e.g., mutations
introduced by random or site-specific mutagenesis in vitro or by
somatic mutation in vivo), for example in the CDRs and in
particular CDR3. However, the term "human antibody", as used
herein, is not intended to include antibodies in which CDR
sequences derived from the germline of another mammalian species,
such as a mouse, have been grafted onto human framework sequences.
The term includes antibodies recombinantly produced in a non-human
mammal, or in cells of a non-human mammal. The term is not intended
to include antibodies isolated from or generated in a human
subject.
[0080] The term "recombinant human antibody", as used herein, is
intended to include all human antibodies that are prepared,
expressed, created or isolated by recombinant means, such as
antibodies expressed using a recombinant expression vector
transfected into a host cell (described further below), antibodies
isolated from a recombinant, combinatorial human antibody library
(described further below), antibodies isolated from an animal
(e.g., a mouse) that is transgenic for human immunoglobulin genes
(see e.g., Taylor et al. (1992) Nucl. Acids Res. 20:6287-6295) or
antibodies prepared, expressed, created or isolated by any other
means that involves splicing of human immunoglobulin gene sequences
to other DNA sequences. Such recombinant human antibodies have
variable and constant regions derived from human germline
immunoglobulin sequences. In certain embodiments, however, such
recombinant human antibodies are subjected to in vitro mutagenesis
(or, when an animal transgenic for human Ig sequences is used, in
vivo somatic mutagenesis) and thus the amino acid sequences of the
V.sub.H and V.sub.L regions of the recombinant antibodies are
sequences that, while derived from and related to human germline
V.sub.H and V.sub.L sequences, may not naturally exist within the
human antibody germline repertoire in vivo.
[0081] Human antibodies can exist in two forms that are associated
with hinge heterogeneity. In one form, an immunoglobulin molecule
comprises a stable four chain construct of approximately 150-160
kDa in which the dimers are held together by an interchain heavy
chain disulfide bond. In a second form, the dimers are not linked
via inter-chain disulfide bonds and a molecule of about 75-80 kDa
is formed composed of a covalently coupled light and heavy chain
(half-antibody). These forms have been extremely difficult to
separate, even after affinity purification.
[0082] The frequency of appearance of the second form in various
intact IgG isotypes is due to, but not limited to, structural
differences associated with the hinge region isotype of the
antibody. A single amino acid substitution in the hinge region of
the human IgG4 hinge can significantly reduce the appearance of the
second form (Angal et al. (1993) Molecular Immunology 30:105) to
levels typically observed using a human IgG1 hinge. The instant
invention encompasses antibodies having one or more mutations in
the hinge, C.sub.H2 or C.sub.H3 region which may be desirable, for
example, in production, to improve the yield of the desired
antibody form.
[0083] An "isolated antibody," as used herein, means an antibody
that has been identified and separated and/or recovered from at
least one component of its natural environment. For example, an
antibody that has been separated or removed from at least one
component of an organism, or from a tissue or cell in which the
antibody naturally exists or is naturally produced, is an "isolated
antibody" for purposes of the present invention. An isolated
antibody also includes an antibody in situ within a recombinant
cell. Isolated antibodies are antibodies that have been subjected
to at least one purification or isolation step. According to
certain embodiments, an isolated antibody may be substantially free
of other cellular material and/or chemicals.
[0084] The term "specifically binds," or the like, means that an
antibody or antigen-binding fragment thereof forms a complex with
an antigen that is relatively stable under physiologic conditions.
Methods for determining whether an antibody specifically binds to
an antigen are well known in the art and include, for example,
equilibrium dialysis, surface plasmon resonance, and the like. For
example, an antibody that "specifically binds" PCSK9, or that
"specifically binds" ANGPTL3, as used in the context of the present
invention, includes antibodies that bind PCSK9, or ANGPTL3, or a
portion thereof with a KD of less than about 1000 nM, less than
about 500 nM, less than about 300 nM, less than about 200 nM, less
than about 100 nM, less than about 90 nM, less than about 80 nM,
less than about 70 nM, less than about 60 nM, less than about 50
nM, less than about 40 nM, less than about 30 nM, less than about
20 nM, less than about 10 nM, less than about 5 nM, less than about
4 nM, less than about 3 nM, less than about 2 nM, less than about 1
nM or less than about 0.5 nM, as measured in a surface plasmon
resonance assay. An isolated antibody that specifically binds human
PCSK9, or human ANGPTL3, however, has cross-reactivity to other
antigens, such as PCSK9 molecules, or ANGPTL3 molecules from other
(non-human) species.
[0085] The anti-PCSK9 and the anti-ANGPTL3 antibodies useful for
the methods of the present invention may comprise one or more amino
acid substitutions, insertions and/or deletions in the framework
and/or CDR regions of the heavy and light chain variable domains as
compared to the corresponding germline sequences from which the
antibodies were derived. Such mutations can be readily ascertained
by comparing the amino acid sequences disclosed herein to germline
sequences available from, for example, public antibody sequence
databases. The present invention includes methods involving the use
of antibodies, and antigen-binding fragments thereof, which are
derived from any of the amino acid sequences disclosed herein,
wherein one or more amino acids within one or more framework and/or
CDR regions are mutated to the corresponding residue(s) of the
germline sequence from which the antibody was derived, or to the
corresponding residue(s) of another human germline sequence, or to
a conservative amino acid substitution of the corresponding
germline residue(s) (such sequence changes are referred to herein
collectively as "germline mutations"). A person of ordinary skill
in the art, starting with the heavy and light chain variable region
sequences disclosed herein, can easily produce numerous antibodies
and antigen-binding fragments which comprise one or more individual
germline mutations or combinations thereof. In certain embodiments,
all of the framework and/or CDR residues within the V.sub.H and/or
V.sub.L domains are mutated back to the residues found in the
original germline sequence from which the antibody was derived. In
other embodiments, only certain residues are mutated back to the
original germline sequence, e.g., only the mutated residues found
within the first 8 amino acids of FR1 or within the last 8 amino
acids of FR4, or only the mutated residues found within CDR1, CDR2
or CDR3. In other embodiments, one or more of the framework and/or
CDR residue(s) are mutated to the corresponding residue(s) of a
different germline sequence (i.e., a germline sequence that is
different from the germline sequence from which the antibody was
originally derived). Furthermore, the antibodies of the present
invention may contain any combination of two or more germline
mutations within the framework and/or CDR regions, e.g., wherein
certain individual residues are mutated to the corresponding
residue of a particular germline sequence while certain other
residues that differ from the original germline sequence are
maintained or are mutated to the corresponding residue of a
different germline sequence. Once obtained, antibodies and
antigen-binding fragments that contain one or more germline
mutations can be easily tested for one or more desired property
such as, improved binding specificity, increased binding affinity,
improved or enhanced antagonistic or agonistic biological
properties (as the case may be), reduced immunogenicity, etc. The
use of antibodies and antigen-binding fragments obtained in this
general manner are encompassed within the present invention.
[0086] The present invention also includes methods involving the
use of anti-PCSK9, and anti-ANGPTL3 antibodies comprising variants
of any of the HCVR, LCVR, and/or CDR amino acid sequences disclosed
herein having one or more conservative substitutions. For example,
the present invention includes the use of anti-PCSK9, and
anti-ANGPTL3 antibodies having HCVR, LCVR, and/or CDR amino acid
sequences with, e.g., 10 or fewer, 8 or fewer, 6 or fewer, 4 or
fewer, etc. conservative amino acid substitutions relative to any
of the HCVR, LCVR, and/or CDR amino acid sequences disclosed
herein.
[0087] The term "surface plasmon resonance", as used herein, refers
to an optical phenomenon that allows for the analysis of real-time
interactions by detection of alterations in protein concentrations
within a biosensor matrix, for example using the BIAcore.TM. system
(Biacore Life Sciences division of GE Healthcare, Piscataway,
N.J).
[0088] The term "KD ", as used herein, is intended to refer to the
equilibrium dissociation constant of a particular antibody-antigen
interaction.
[0089] The term "epitope" refers to an antigenic determinant that
interacts with a specific antigen binding site in the variable
region of an antibody molecule known as a paratope. A single
antigen may have more than one epitope. Thus, different antibodies
may bind to different areas on an antigen and may have different
biological effects. Epitopes may be either conformational or
linear. A conformational epitope is produced by spatially
juxtaposed amino acids from different segments of the linear
polypeptide chain. A linear epitope is one produced by adjacent
amino acid residues in a polypeptide chain. In certain
circumstance, an epitope may include moieties of saccharides,
phosphoryl groups, or sulfonyl groups on the antigen.
[0090] According to certain embodiments, the anti-PCSK9 and
anti-ANGPTL3 antibodies used in the methods of the present
invention are antibodies with pH-dependent binding characteristics.
As used herein, the expression "pH-dependent binding" means that
the antibody or antigen-binding fragment thereof exhibits "reduced
binding to PCSK9 at acidic pH as compared to neutral pH" (for
purposes of the present disclosure, both expressions may be used
interchangeably), or that the antibody or antigen-binding fragment
thereof exhibits "reduced binding to ANGPTL3 at acidic pH as
compared to neutral pH" (for purposes of the present disclosure,
both expressions may be used interchangeably). For the example,
antibodies "with pH-dependent binding characteristics" includes
antibodies and antigen-binding fragments thereof that bind either
to PCSK9, or to ANGPTL3 with higher affinity at neutral pH than at
acidic pH. In certain embodiments, the antibodies and
antigen-binding fragments of the present invention bind PCSK9, or
ANGPTL3 with at least 3, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55,
60, 65, 70, 75, 80, 85, 90, 95, 100, or more times higher affinity
at neutral pH than at acidic pH.
[0091] According to this aspect of the invention, the anti-PCSK9
antibodies, or the ANGPTL3 antibodies with pH-dependent binding
characteristics may possess one or more amino acid variations
relative to the parental anti-PCSK9 antibody, or the parental
anti-ANGPTL3 antibody. For example, an anti-PCSK9 antibody, or an
anti-ANGPTL3 antibody with pH-dependent binding characteristics may
contain one or more histidine substitutions or insertions, e.g., in
one or more CDRs of a parental anti-PCSK9, or a parental
anti-ANGPTL3 antibody. Thus, according to certain embodiments of
the present invention, methods are provided comprising
administering an anti-PCSK9 antibody and an anti-ANGPTL3 antibody
which comprises CDR amino acid sequences (e.g., heavy and light
chain CDRs) which are identical to the CDR amino acid sequences of
a parental anti-PCSK9 antibody, or parental ANGPTL3 antibody except
for the substitution of one or more amino acids of one or more CDRs
of the parental antibody with a histidine residue. The anti-PCSK9
antibodies, or anti-ANGPTL3 antibodies with pH-dependent binding
may possess, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or more histidine
substitutions, either within a single CDR of a parental antibody or
distributed throughout multiple (e.g., 2, 3, 4, 5, or 6) CDRs of a
parental anti-PCSK9 antibody, or a parental anti-ANGPTL3 antibody.
For example, the present invention includes the use of anti-PCSK9
antibodies and anti-ANGPTL3 antibodies with pH-dependent binding
comprising one or more histidine substitutions in HCDR1, one or
more histidine substitutions in HCDR2, one or more histidine
substitutions in HCDR3, one or more histidine substitutions in
LCDR1, one or more histidine substitutions in LCDR2, and/or one or
more histidine substitutions in LCDR3, of a parental anti-PCSK9
antibody, or a parental anti-ANGPTL3 antibody.
[0092] As used herein, the expression "acidic pH" means a pH of 6.0
or less (e.g., less than about 6.0, less than about 5.5, less than
about 5.0, etc.). The expression "acidic pH" includes pH values of
about 6.0, 5.95, 5.90, 5.85, 5.8, 5.75, 5.7, 5.65, 5.6, 5.55, 5.5,
5.45, 5.4, 5.35, 5.3, 5.25, 5.2, 5.15, 5.1, 5.05, 5.0, or less. As
used herein, the expression "neutral pH" means a pH of about 7.0 to
about 7.4. The expression "neutral pH" includes pH values of about
7.0, 7.05, 7.1, 7.15, 7.2, 7.25, 7.3, 7.35, and 7.4.
[0093] Non-limiting examples of anti-PCSK9 antibodies that can be
used in the context of the present invention include, e.g.,
alirocumab, evolocumab, bococizumab, lodelcizumab, ralpancizumab,
or antigen-binding portions of any of the foregoing antibodies.
[0094] A non-limiting example of an anti-ANGPTL3 antibody that can
be used in the context of the present invention includes
evinacumab.
Preparation of Human Antibodies
[0095] Anti-PCSK9 antibodies and anti-ANGPTL3 antibodies can be
made according to any method of antibody production/isolation known
in the art. For example, antibodies for use in the methods of the
present invention may be made by hybridoma technologies, by phage
display, by yeast display, etc. Antibodies for use in the methods
of the present invention may be, e.g., chimeric antibodies,
humanized antibodies, or fully human antibodies.
[0096] Methods for generating human antibodies in transgenic mice
are known in the art. Any such known methods can be used in the
context of the present invention to make human antibodies that
specifically bind PCSK9, or ANGPTL3.
[0097] For example, using VELOCIMMUNE.TM. technology (see, for
example, U.S. Pat. No. 6,596,541, Regeneron Pharmaceuticals) or any
other known method for generating monoclonal antibodies, high
affinity chimeric antibodies to PCSK9, or to ANGPTL3 are initially
isolated having a human variable region and a mouse constant
region. The VELOCIMMUNE.RTM. technology involves generation of a
transgenic mouse having a genome comprising human heavy and light
chain variable regions operably linked to endogenous mouse constant
region loci such that the mouse produces an antibody comprising a
human variable region and a mouse constant region in response to
antigenic stimulation. The DNA encoding the variable regions of the
heavy and light chains of the antibody are isolated and operably
linked to DNA encoding the human heavy and light chain constant
regions. The DNA is then expressed in a cell capable of expressing
the fully human antibody.
[0098] Generally, a VELOCIMMUNE.RTM. mouse is challenged with the
antigen of interest, and lymphatic cells (such as B-cells) are
recovered from the mice that express antibodies. The lymphatic
cells may be fused with a myeloma cell line to prepare immortal
hybridoma cell lines, and such hybridoma cell lines are screened
and selected to identify hybridoma cell lines that produce
antibodies specific to the antigen of interest. DNA encoding the
variable regions of the heavy chain and light chain may be isolated
and linked to desirable isotypic constant regions of the heavy
chain and light chain. Such an antibody protein may be produced in
a cell, such as a CHO cell. Alternatively, DNA encoding the
antigen-specific chimeric antibodies or the variable domains of the
light and heavy chains may be isolated directly from
antigen-specific lymphocytes.
[0099] Initially, high affinity chimeric antibodies are isolated
having a human variable region and a mouse constant region. The
antibodies are characterized and selected for desirable
characteristics, including affinity, selectivity, epitope, etc.,
using standard procedures known to those skilled in the art. The
mouse constant regions are replaced with a desired human constant
region to generate the fully human antibody of the invention, for
example wild-type or modified IgG1 or IgG4. While the constant
region selected may vary according to specific use, high affinity
antigen-binding and target specificity characteristics reside in
the variable region.
[0100] In general, the antibodies that can be used in the methods
of the present invention possess high affinities, as described
above, when measured by binding to antigen either immobilized on
solid phase or in solution phase. The mouse constant regions are
replaced with desired human constant regions to generate the fully
human antibodies of the invention. While the constant region
selected may vary according to specific use, high affinity
antigen-binding and target specificity characteristics reside in
the variable region.
[0101] Specific examples of human antibodies or antigen-binding
fragments of antibodies that specifically bind PCSK9, which can be
used in the context of the methods of the present invention include
antibodies or antigen-binding proteins comprising the six CDRs
(HCDR1, HCDR2, HCDR3, LCDR1, LCDR2 and LCDR3) from the heavy and
light chain variable region (HCVR/LCVR) amino acid sequence pair
comprising SEQ ID NOs: 12/17.
[0102] In certain embodiments of the present invention, the
anti-PCSK9 antibody, or antigen-binding fragment thereof, that can
be used in the methods of the present invention comprises heavy and
light chain complementarity determining regions
(HCDR1-HCDR2-HCDR3/LCDR1-LCDR2-LCDR3) comprising the amino acid
sequences of SEQ ID NOs:13, 14, 15, 18, 19 and 21.
[0103] In certain embodiments of the present invention, the
anti-PCSK9 antibody, or antigen-binding fragment thereof, that can
be used in the methods of the present invention comprises an HCVR
having the amino acid sequence of SEQ ID NO:12 and an LCVR having
the amino acid sequence of SEQ ID NO:17.
[0104] Specific examples of human antibodies or antigen-binding
fragments of antibodies that specifically bind ANGPTL3, which can
be used in the context of the methods of the present invention
include antibodies or antigen-binding proteins comprising the six
CDRs (HCDR1, HCDR2, HCDR3, LCDR1, LCDR2 and LCDR3) from the heavy
and light chain variable region (HCVR/LCVR) amino acid sequence
pair comprising SEQ ID NOs: 2/3.
[0105] In certain embodiments of the present invention, the
anti-ANGPTL3 antibody, or antigen-binding fragment thereof, that
can be used in the methods of the present invention comprises heavy
and light chain complementarity determining regions
(HCDR1-HCDR2-HCDR3/LCDR1-LCDR2-LCDR3) comprising the amino acid
sequences of SEQ ID NOs:4, 5, 6, 7, 8 and 9.
[0106] In certain embodiments of the present invention, the
anti-ANGPTL3 antibody, or antigen-binding fragment thereof, that
can be used in the methods of the present invention comprises an
HCVR having the amino acid sequence of SEQ ID NO:2 and an LCVR
having the amino acid sequence of SEQ ID NO:3.
Pharmaceutical Compositions and Methods of Administration
[0107] The present invention includes methods, which comprise
administering a PCSK9 inhibitor to a patient in combination with an
ANGPTL3 inhibitor, wherein the PCSK9 inhibitor and the ANGPTL3
inhibitor are contained within the same, or in different
pharmaceutical compositions. The pharmaceutical compositions of the
invention are formulated with suitable carriers, excipients, and
other agents that provide suitable transfer, delivery, tolerance,
and the like. A multitude of appropriate formulations can be found
in the formulary known to all pharmaceutical chemists: Remington's
Pharmaceutical Sciences, Mack Publishing Company, Easton, PA. These
formulations include, for example, powders, pastes, ointments,
jellies, waxes, oils, lipids, lipid (cationic or anionic)
containing vesicles (such as LIPOFECTINTM), DNA conjugates,
anhydrous absorption pastes, oil-in-water and water-in-oil
emulsions, emulsions carbowax (polyethylene glycols of various
molecular weights), semi-solid gels, and semi-solid mixtures
containing carbowax. See also Powell et al. "Compendium of
excipients for parenteral formulations" PDA (1998) J Pharm Sci
Technol 52:238-311.
[0108] Exemplary pharmaceutical formulations comprising anti-PCSK9
antibodies, and/or ANGPTL3 antibodies that can be used in the
context of the present invention include any of the formulations as
set forth in U.S. Pat. No. 8,795,669 (describing, inter alia,
exemplary formulations comprising alirocumab), or in WO2013/166448,
or WO2012/168491.
[0109] Various delivery systems are known and can be used to
administer the pharmaceutical composition of the invention, e.g.,
encapsulation in liposomes, microparticles, microcapsules,
recombinant cells capable of expressing the mutant viruses,
receptor mediated endocytosis (see, e.g., Wu et al., 1987, J. Biol.
Chem. 262:4429-4432). Methods of administration include, but are
not limited to, intradermal, intramuscular, intraperitoneal,
intravenous, subcutaneous, intranasal, epidural, and oral routes.
The composition may be administered by any convenient route, for
example by infusion or bolus injection, by absorption through
epithelial or mucocutaneous linings (e.g., oral mucosa, rectal and
intestinal mucosa, etc.) and may be administered together with
other biologically active agents.
[0110] A pharmaceutical composition of the present invention can be
delivered subcutaneously or intravenously with a standard needle
and syringe. In addition, with respect to subcutaneous delivery, a
pen delivery device readily has applications in delivering a
pharmaceutical composition of the present invention. Such a pen
delivery device can be reusable or disposable. A reusable pen
delivery device generally utilizes a replaceable cartridge that
contains a pharmaceutical composition. Once all of the
pharmaceutical composition within the cartridge has been
administered and the cartridge is empty, the empty cartridge can
readily be discarded and replaced with a new cartridge that
contains the pharmaceutical composition. The pen delivery device
can then be reused. In a disposable pen delivery device, there is
no replaceable cartridge. Rather, the disposable pen delivery
device comes prefilled with the pharmaceutical composition held in
a reservoir within the device. Once the reservoir is emptied of the
pharmaceutical composition, the entire device is discarded.
[0111] Numerous reusable pen and autoinjector delivery devices have
applications in the subcutaneous delivery of a pharmaceutical
composition of the present invention. Examples include, but are not
limited to AUTOPENTM (Owen Mumford, Inc., Woodstock, UK),
DISETRONIC.TM. pen (Disetronic Medical Systems, Bergdorf,
Switzerland), HUMALOG MIX 75/25.TM. pen, HUMALOG.TM. pen, HUMALIN
70/30.TM. pen (Eli Lilly and Co., Indianapolis, Ind.), NOVOPEN.TM.
I, II and III (Novo Nordisk, Copenhagen, Denmark), NOVOPEN
JUNIOR.TM. (Novo Nordisk, Copenhagen, Denmark), BD.TM. pen (Becton
Dickinson, Franklin Lakes, N.J.), OPTIPENTM, OPTIPEN PRO.TM. ,
OPTIPEN STARLET.TM. , and OPTICLIK.TM. (Sanofi-Aventis, Frankfurt,
Germany), to name only a few. Examples of disposable pen delivery
devices having applications in subcutaneous delivery of a
pharmaceutical composition of the present invention include, but
are not limited to the SOLOSTAR.TM. pen (Sanofi-Aventis), the
FLEXPEN.TM. (Novo Nordisk), and the KWIKPEN.TM. (Eli Lilly), the
SURECLICK.TM. Autoinjector (Amgen, Thousand Oaks, Calif.), the
PENLET.TM. (Haselmeier, Stuttgart, Germany), the EPIPEN (Dey,
L.P.), and the HUMIRA.TM. Pen (Abbott Labs, Abbott Park Ill.), to
name only a few.
[0112] In certain situations, the pharmaceutical composition can be
delivered in a controlled release system. In one embodiment, a pump
may be used (see Langer, supra; Sefton, 1987, CRC Crit. Ref.
Biomed. Eng. 14:201). In another embodiment, polymeric materials
can be used; see, Medical Applications of Controlled Release,
Langer and Wise (eds.), 1974, CRC Pres., Boca Raton, Florida. In
yet another embodiment, a controlled release system can be placed
in proximity of the composition's target, thus requiring only a
fraction of the systemic dose (see, e.g., Goodson, 1984, in Medical
Applications of Controlled Release, supra, vol. 2, pp. 115-138).
Other controlled release systems are discussed in the review by
Langer, 1990, Science 249:1527-1533.
[0113] The injectable preparations may include dosage forms for
intravenous, subcutaneous, intracutaneous and intramuscular
injections, drip infusions, etc. These injectable preparations may
be prepared by known methods. For example, the injectable
preparations may be prepared, e.g., by dissolving, suspending or
emulsifying the antibody or its salt described above in a sterile
aqueous medium or an oily medium conventionally used for
injections. As the aqueous medium for injections, there are, for
example, physiological saline, an isotonic solution containing
glucose and other auxiliary agents, etc., which may be used in
combination with an appropriate solubilizing agent such as an
alcohol (e.g., ethanol), a polyalcohol (e.g., propylene glycol,
polyethylene glycol), a nonionic surfactant [e.g., polysorbate 80,
HCO-50 (polyoxyethylene (50 mol) adduct of hydrogenated castor
oil)], etc. As the oily medium, there are employed, e.g., sesame
oil, soybean oil, etc., which may be used in combination with a
solubilizing agent such as benzyl benzoate, benzyl alcohol, etc.
The injection thus prepared is preferably filled in an appropriate
ampoule.
[0114] Advantageously, the pharmaceutical compositions for oral or
parenteral use described above are prepared into dosage forms in a
unit dose suited to fit a dose of the active ingredients. Such
dosage forms in a unit dose include, for example, tablets, pills,
capsules, injections (ampoules), suppositories, etc.
Dosage
[0115] The amount of a PCSK9 inhibitor (e.g., anti-PCSK9 antibody),
or an ANGPTL3 inhibitor (e.g., anti-ANGPTL3 antibody) administered
to a subject according to the methods of the present invention is,
generally, a therapeutically effective amount. As used herein, the
phrase "therapeutically effective amount of a PCSK9 inhibitor"
means a dose of a PCSK9 inhibitor, when administered in combination
with an ANGPTL3 inhibitor, results in a detectable reduction (at
least about 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%,
60%, 65%, 70%, 75%, or more from baseline) in one or more
parameters selected from the group consisting of total cholesterol,
LDL-C, ApoB100, non-HDL-C, VLDL-C, triglycerides, Lp(a) and remnant
cholesterol, or an amount that reduces or eliminates a patient's
need for other therapeutic interventions, such as, lipoprotein
apheresis, or that reduces a patient's normalized rate of
apheresis.
[0116] In the case of an anti-PCSK9 antibody, a therapeutically
effective amount can be from about 0.05 mg to about 600 mg, e.g.,
about 0.05 mg, about 0.1 mg, about 1.0 mg, about 1.5 mg, about 2.0
mg, about 10 mg, about 20 mg, about 30 mg, about 40 mg, about 50

mg, about 540 mg, about 550 mg, about 560 mg, about 570 mg, about
580 mg, about 590 mg, or about 600 mg, of the anti-PCSK9 antibody.
According to certain exemplary embodiments of the present
invention, a therapeutically effective amount of an anti-PCSK9
antibody is 75 mg, 150 mg or 300 mg (e.g., in the case of
alirocumab), or 140 mg or 420 mg (e.g., in the case of evolocumab).
Other dosing amounts of PCSK9 inhibitors will be apparent to
persons of ordinary skill in the art and are contemplated within
the scope of the present invention.
[0117] The amount of anti-PCSK9 antibody contained within the
individual doses may be expressed in terms of milligrams of
antibody per kilogram of patient body weight (i.e., mg/kg). For
example, the anti-PCSK9 antibody may be administered to a patient
at a dose of about 0.0001 to about 10 mg/kg of patient body
weight.
[0118] The amount of ANGPTL3 inhibitor (e.g., anti-ANGPTL3
antibody) administered to a subject according to the methods of the
present invention is, generally, a therapeutically effective
amount. As used herein, the phrase "therapeutically effective
amount of an ANGPTL3 inhibitor" means a dose of ANGPTL3 inhibitor,
when combined with a PCSK9 inhibitor, results in a detectable
reduction (at least about 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%,
45%, 50%, 55%, 60%, 65%, 70%, 75%, or more from baseline) in one or
more parameters selected from the group consisting of total
cholesterol, LDL-C, ApoB100, non-HDL-C, VLDL-C, triglycerides,
Lp(a) and remnant cholesterol, or an amount that prevents or
attenuates atherosclerosis in a subject (as described elsewhere
herein).
[0119] In the case of an anti-ANGPTL3 antibody, a therapeutically
effective amount can be from about 0.05 mg to about 600 mg, e.g.,
about 0.05 mg, about 0.1 mg, about 1.0 mg, about 1.5 mg, about 2.0
mg, about 10 mg, about 20 mg, about 30 mg, about 40 mg, about 50
mg, about 60 mg, about 70 mg, about 80 mg, about 90 mg, about 100
mg, about 110 mg, about 120 mg, about 130 mg, about 140 mg, about
160 mg, about 170 mg, about 180 mg, about 190 mg, about 200 mg,
about 210 mg, about 220 mg, about 230 mg, about 240 mg, about 250
mg, about 260 mg, about 270 mg, about 280 mg, about 290 mg, about
300 mg, about 310 mg, about 320 mg, about 330 mg, about 340 mg,
about 350 mg, about 360 mg, about 370 mg, about 380 mg, about 390
mg, about 400 mg, about 410 mg, about 420 mg, about 430 mg, about
440 mg, about 450 mg, about 460 mg, about 470 mg, about 480 mg,

mg, about 540 mg, about 550 mg, about 560 mg, about 570 mg, about
580 mg, about 590 mg, or about 600 mg, of the anti-ANGPTL3
antibody. Other dosing amounts of ANGPTL3 inhibitors will be
apparent to persons of ordinary skill in the art and are
contemplated within the scope of the present invention.
[0120] The amount of anti-ANGPTL3 antibody contained within the
individual doses may be expressed in terms of milligrams of
antibody per kilogram of patient body weight (i.e., mg/kg). For
example, the anti-ANGPTL3 antibody may be administered to a patient
at a dose of about 0.0001 to about 10 mg/kg of patient body
weight.
Combination Therapies
[0121] As described elsewhere herein, the methods of the present
invention may comprise administering a PCSK9 inhibitor in
combination with an ANGPTL3 inhibitor to a patient who is
non-responsive to, inadequately controlled by, or intolerant to a
standard lipid lowering therapy. In certain embodiments, the need
for further administration of the lipid lowering therapy may be
eliminated altogether. In certain embodiments, the combined use of
the PCSK9 inhibitor with the ANGPTL3 inhibitor may be used in
combination with ("on top of") the patient's previously prescribed
lipid lowering therapy. For example, in the context of lowering at
least one lipid/lipoprotein parameter in a patient suffering from
hyperlipidemia (e.g. hypercholesterolemia), wherein the patient is
non-responsive to, inadequately controlled by, or intolerant to a
standard lipid lowering therapy, a combination of a PCSK9 inhibitor
with an ANGPTL3 inhibitor may be administered to a patient in
combination with a stable daily therapeutic statin regimen.
Exemplary daily therapeutic statin regimens that a PCSK9 inhibitor
plus an ANGPTL3 inhibitor may be administered in combination with
in the context of the present invention include, e.g., atorvastatin
(10, 20, 40 or 80 mg daily), (atorvastatin/ezetimibe 10/10 or 40/10
mg daily), rosuvastatin (5, 10 or 20 mg daily), cerivastatin (0.4
or 0.8 mg daily), pitavastatin (1, 2 or 4 mg daily), fluvastatin
(20, 40 or 80 mg daily), simvastatin (5, 10, 20, 40 or 80 mg
daily), simvastatin/ezetimibe (10/10, 20/10, 40/10 or 80/10 mg
daily), lovastatin (10, 20, 40 or 80 mg daily), pravastatin (10,
20, 40 or 80 mg daily), and combinations thereof. Other lipid
modifying therapies that a PCSK9 inhibitor plus an ANGPTL3
inhibitor may be administered in combination with in the context of
the present invention include, e.g., (1) an agent which inhibits
cholesterol uptake and or bile acid re-absorption (e.g.,
ezetimibe); (2) an agent which increase lipoprotein catabolism
(such as niacin); and/or (3) activators of the LXR transcription
factor that plays a role in cholesterol elimination such as
22-hydroxycholesterol.
[0122] Non-limiting examples of anti-PCSK9 antibodies that can be
used in the context of the present invention include, e.g.,
alirocumab, evolocumab, bococizumab, lodelcizumab, ralpancizumab,
or antigen-binding portions of any of the foregoing antibodies.
[0123] A non-limiting example of an ANGPTL3 antibody to be used in
the context of the present invention includes evinacumab.
Administration Regimens
[0124] According to certain embodiments of the present invention,
multiple doses of a PCSK9 inhibitor (i.e., a pharmaceutical
composition comprising a PCSK9 inhibitor) and an ANGPTL3 inhibitor
(i.e., a pharmaceutical composition comprising an ANGPTL3
inhibitor) may be administered to a subject over a defined time
course (e.g., on top of a daily therapeutic statin regimen or other
background lipid modifying therapy). The methods according to this
aspect of the invention comprise sequentially administering to a
subject multiple doses of a PCSK9 inhibitor and an ANGPTL3
inhibitor. As used herein, "sequentially administering" means that
each dose of PCSK9 inhibitor and ANGPTL3 inhibitor is administered
to the subject at a different point in time, e.g., on different
days separated by a predetermined interval (e.g., hours, days,
weeks or months). The present invention includes methods which
comprise sequentially administering to the patient a single initial
dose of a PCSK9 inhibitor and an ANGPTL3 inhibitor, followed by one
or more secondary doses of the PCSK9 inhibitor and ANGPTL3
inhibitor, and optionally followed by one or more tertiary doses of
the PCSK9 inhibitor and ANGPTL3 inhibitor.
[0125] The terms "initial dose," "secondary doses," and "tertiary
doses," refer to the temporal sequence of administration of the
individual doses of a pharmaceutical composition comprising a PCSK9
inhibitor and the ANGPTL3 inhibitor. Thus, the "initial dose" is
the dose which is administered at the beginning of the treatment
regimen (also referred to as the "baseline dose"); the "secondary
doses" are the doses which are administered after the initial dose;
and the "tertiary doses" are the doses which are administered after
the secondary doses. The initial, secondary, and tertiary doses may
all contain the same amount of the PCSK9 inhibitor and the ANGPTL3
inhibitor, but generally may differ from one another in terms of
frequency of administration. In certain embodiments, however, the
amount of PCSK9 inhibitor and the ANGPTL3 inhibitor contained in
the initial, secondary and/or tertiary doses varies from one
another (e.g., adjusted up or down as appropriate) during the
course of treatment. In certain embodiments, two or more (e.g., 2,
3, 4, or 5) doses are administered at the beginning of the
treatment regimen as "loading doses" followed by subsequent doses
that are administered on a less frequent basis (e.g., "maintenance
doses").
[0126] According to exemplary embodiments of the present invention,
each secondary and/or tertiary dose is administered 1 to 26 (e.g.,
1, 11/2, 2, 21/2, 3, 31/2, 4, 41/2, 5, 51/2, 6, 61/2, 7, 71/2, 8,
81/2, 9, 91/2, 10, 101/2, 11, 111/2, 12, 121/2, 13, 131/2, 14,
141/2, 15, 151/2, 16, 161/2, 17, 171/2, 18, 181/2, 19, 191/2, 20,
201/2, 21, 211/2, 22, 221/2, 23, 231/2, 24, 241/2, 25, 251/2, 26,
261/2, or more) weeks after the immediately preceding dose. The
phrase "the immediately preceding dose," as used herein, means, in
a sequence of multiple administrations, the dose of antigen-binding
molecule, which is administered to a patient prior to the
administration of the very next dose in the sequence with no
intervening doses.
[0127] The methods according to this aspect of the invention may
comprise administering to a patient any number of secondary and/or
tertiary doses of a PCSK9 inhibitor and ANGPTL3 inhibitor. For
example, in certain embodiments, only a single secondary dose is
administered to the patient. In other embodiments, two or more
(e.g., 2, 3, 4, 5, 6, 7, 8, or more) secondary doses are
administered to the patient. Likewise, in certain embodiments, only
a single tertiary dose is administered to the patient. In other
embodiments, two or more (e.g., 2, 3, 4, 5, 6, 7, 8, or more)
tertiary doses are administered to the patient.
[0128] In embodiments involving multiple secondary doses, each
secondary dose may be administered at the same frequency as the
other secondary doses. For example, each secondary dose may be
administered to the patient 1 to 2, 4, 6, 8 or more weeks after the
immediately preceding dose. Similarly, in embodiments involving
multiple tertiary doses, each tertiary dose may be administered at
the same frequency as the other tertiary doses. For example, each
tertiary dose may be administered to the patient 1 to 2, 4, 6, 8 or
more weeks after the immediately preceding dose. Alternatively, the
frequency at which the secondary and/or tertiary doses are
administered to a patient can vary over the course of the treatment
regimen. The frequency of administration may also be adjusted
during the course of treatment by a physician depending on the
needs of the individual patient following clinical examination.

Example 3
In Vivo Effect of Treatment with a Combination of an Anti-hANGPTL3
Antibody and an Anti-PCSK9 Antibody on Circulating Lipid Levels in
Hyperlipidemic Ldlr.sup.-/+ mice
[0132] The effect of anti-hANGPTL3 antibody H4H1276 (evinacumab)
alone, anti-PCSK9 antibody H1H316P (alirocumab) alone and both
antibodies in combination on serum lipids levels was determined in
LDLR -/.+-.mice. These mice are hyperlipidemic with majority of
their circulating cholesterol found in the form of LDL due to
partial deficiency in LDLR, the major receptor for LDL-C
uptake.
[0133] In the first study, male LDLR.sup.-/+ mice on chow diet were
pre-bled 5 days before the experiment and mice were put into groups
of five mice each. The antibodies, H4H1276P, H1H316P, their
combination and isotype-matched (hlgG4) control with irrelevant
specificity, were administered at a dose of 10mg/kg each by
subcutaneous injection on Day 0 of the study. Mice were bled after
4 hours of fasting on consecutive days after the antibodies
injections and serum lipids levels (Total Cholesterol, LDL-C,
Non-HDL-C and HDL-C) were determined in the serum by ADVIA.RTM.
1800 Chemistry System (Siemens). Averages per group were calculated
for each of the time points. Results, expressed as mean .+-.SEM of
serum lipids concentration, are shown in FIGS. 1, 2, 3, and 4.
[0134] In the second study, male LDLR.sup.-/+ mice were placed on a
high fat Western diet for 3 weeks before injection of the
antibodies and the mice were fed this diet through the duration of
the study. The rest of the study was conducted under the same
protocol as for the first study. Results, expressed as mean.+-.SEM
of serum lipids concentration, are shown in FIGS. 5, 6, 7 and
8.
[0135] Levels of circulating antibodies (Serum Ab) for both studies
were determined using a standard ELISA assay. Briefly, plates were
coated with a goat anti-human Fc antibody (Sigma-Aldrich) to
capture Serum Ab. Serum was then added to the plates and captured
antibodies were detected by chemiluminescence using a horseradish
peroxidase (HRP) conjugated goat anti-human IgG antibody
(Sigma-Aldrich). Results, expressed as mean.+-.SEM are shown in
Tables 1 A and 1B (first study) and Tables 2A and 2B (second
study). Control: Mice that received an isotype-matched Control
Ab
Results Summary:
[0136] The administration of the combination of H1 H316P and
H4H1276P as single subcutaneous doses to LDLR.sup.-/+ mice on chow
and high fat Western diet lead to a significant reduction in total
cholesterol, LDL-C and non-HDL-C and had an additive affect on
serum lipid levels when compared to the respective single
administration of each antibody.
