THOUSAND OAKS, Calif., Dec. 17, 2013 /PRNewswire/ --Amgen (NASDAQ:AMGN) today
announced that the Phase 3 MENDEL-2 (Monoclonal Antibody Against PCSK9 to
Reduce Elevated LDL-C in Subjects Currently Not Receiving Drug Therapy for
Easing Lipid Levels-2) trial with evolocumab met its co-primary endpoints: the
percent reduction from baseline in low-density lipoprotein cholesterol (LDL-C)
at week 12 and the mean percent reduction from baseline in LDL-C at weeks 10
and 12. The mean percent reductions in LDL-C, or "bad" cholesterol, compared
to placebo and ezetimibe were consistent with results observed in the MENDEL
Phase 2 study.

Evolocumab is an investigational fully human monoclonal antibody that inhibits
proprotein convertase subtilisin/kexin type 9 (PCSK9), a protein that reduces
the liver's ability to remove LDL-C from the blood.^1

The MENDEL-2 trial evaluated safety, tolerability and efficacy of evolocumab
in 614 patients with high cholesterol (LDL-C ≥ 100 mg/dL and < 190 mg/dL) who
were not receiving lipid-lowering therapy. Patients were randomized to one of
six treatment groups to compare two dosing regimens of evolocumab (140 mg
every two weeks or 420 mg monthly) with placebo and ezetimibe (10 mg daily).

Safety was balanced across treatment groups. The most common (>2 percent in
evolocumab combined group) adverse events (AEs) were headache, diarrhea,
nausea and urinary tract infection.

"Data from the MENDEL-2 monotherapy study in more than 600 patients provide
the first of Phase 3 results from our comprehensive development program for
evolocumab," said Sean E. Harper, M.D., executive vice president of Research
and Development at Amgen. "The positive results we have seen with two distinct
dosing options suggest that evolocumab may offer a promising approach to treat
patients with high cholesterol."

Details of the MENDEL-2 study results will be submitted to a future medical
conference and for publication.

According to the Centers for Disease Control and Prevention, more than 71
million American adults have high LDL-C.^2 Elevated LDL-C is recognized as a
major risk factor for cardiovascular disease.^3-4

MENDEL-2 Study Design

MENDEL-2 (Monoclonal Antibody Against PCSK9 to Reduce Elevated LDL-C in
Patients Currently Not Receiving Drug Therapy For Easing Lipid Levels-2) is a
Phase 3 randomized, multi-center, double-blind, double-dummy, stratified,
placebo and ezetimibe-controlled parallel group study designed to evaluate the
efficacy and safety of evolocumab in 614 hyperlipidemic patients with a
10-year Framingham risk score of 10 percent or less who were not receiving
lipid-lowering therapy. Patients were randomized to one of six treatment
groups to compare two dosing regimens of evolocumab (140 mg every two weeks or
420 mg monthly) with placebo and ezetimibe (10 mg daily). The co-primary
endpoints were the percent reduction from baseline in LDL-C at week 12 and the
mean percent reduction from baseline in LDL-C at weeks 10 and 12.Secondary
efficacy endpoints included the absolute change from baseline in LDL-C at week
12 and the percentage changes from baseline at week 12 in non-high-density
lipoprotein cholesterol (non-HDL-C), apolipoprotein B (ApoB), total
cholesterol (TC)/HDL-C, ApoB/apolipoprotein A1 (ApoA1) ratio, lipoprotein(a),
triglycerides, HDL-C and very LDL-C (VLDL-C).

About PROFICIO: The Evolocumab Clinical Trial Program

PROFICIO, which stands for the Program to Reduce LDL-C and Cardiovascular
Outcomes Following Inhibition of PCSK9 In Different POpulations, is a large
and comprehensive clinical trial program evaluating evolocumab. Phase 3
clinical trials for evolocumab are currently underway and build upon the Phase
2 studies.

The Phase 3 program includes 13 trials, with a combined planned enrollment of
more than 28,000 patients. The Phase 3 studies will evaluate evolocumab
administered every two weeks and monthly in multiple patient populations,
including in combination with statins in patients with hyperlipidemia
(LAPLACE-2), in patients with hyperlipidemia who cannot tolerate statins
(GAUSS-2), as a stand-alone treatment in patients with hyperlipidemia
(MENDEL-2), and in patients whose elevated cholesterol is caused by genetic
disorders called heterozygous (RUTHERFORD-2) and homozygous (TESLA and
TAUSSIG) familial hypercholesterolemia.

Five studies of evolocumab will provide long-term safety and efficacy data.
These include FOURIER (Further Cardiovascular OUtcomes Research with PCSK9
Inhibition in Subjects with Elevated Risk), which will assess whether
treatment with evolocumab in combination with statin therapy compared to
placebo and statin therapy reduces recurrent cardiovascular events in
approximately 22,500 patients with cardiovascular disease, and GLAGOV (GLobal
Assessment of Plaque ReGression with a PCSK9 AntibOdy as Measured by
IntraVascular Ultrasound), which will determine the effect of evolocumab on
coronary atherosclerosis in approximately 950 patients undergoing cardiac
catheterization.

About Evolocumab

Evolocumab is a fully human monoclonal antibody that inhibits proprotein
convertase subtilisin/kexin type 9 (PCSK9).^1 PCSK9 is a protein that targets
LDL receptors for degradation and thereby reduces the liver's ability to
remove LDL-C, or "bad" cholesterol, from the blood.^5 Evolocumab, being
developed by Amgen scientists, is designed to bind to PCSK9 and inhibit PCSK9
from binding to LDL receptors on the liver surface. In the absence of PCSK9,
there are more LDL receptors on the surface of the liver to remove LDL-C from
the blood.^1

management's current expectations and beliefs and are subject to a number of
risks, uncertainties and assumptions that could cause actual results to differ
materially from those described. All statements, other than statements of
historical fact, are statements that could be deemed forward-looking
statements, including estimates of revenues, operating margins, capital
expenditures, cash, other financial metrics, expected legal, arbitration,
political, regulatory or clinical results or practices, customer and
prescriber patterns or practices, reimbursement activities and outcomes and
other such estimates and results. Forward-looking statements involve
significant risks and uncertainties, including those discussed below and more
fully described in the Securities and Exchange Commission (SEC) reports filed
by Amgen, including Amgen's most recent annual report on Form 10-K and any
subsequent periodic reports on Form 10-Q and Form 8-K. Please refer to Amgen's
most recent Forms 10-K, 10-Q and 8-K for additional information on the
uncertainties and risk factors related to our business. Unless otherwise
noted, Amgen is providing this information as of Dec. 17, 2013, and expressly
disclaims any duty to update information contained in this news release.

No forward-looking statement can be guaranteed and actual results may differ
materially from those we project. Discovery or identification of new product
candidates or development of new indications for existing products cannot be
guaranteed and movement from concept to product is uncertain; consequently,
there can be no guarantee that any particular product candidate or development
of a new indication for an existing product will be successful and become a
commercial product. Further, preclinical results do not guarantee safe and
effective performance of product candidates in humans. The complexity of the
human body cannot be perfectly, or sometimes, even adequately modeled by
computer or cell culture systems or animal models. The length of time that it
takes for us to complete clinical trials and obtain regulatory approval for
product marketing has in the past varied and we expect similar variability in
the future. We develop product candidates internally and through licensing
collaborations, partnerships and joint ventures. Product candidates that are
derived from relationships may be subject to disputes between the parties or
may prove to be not as effective or as safe as we may have believed at the
time of entering into such relationship. Also, we or others could identify
safety, side effects or manufacturing problems with our products after they
are on the market. Our business may be impacted by government investigations,
litigation and products liability claims. We depend on third parties for a
significant portion of our manufacturing capacity for the supply of certain of
our current and future products and limits on supply may constrain sales of
certain of our current products and product candidate development.

In addition, sales of our products are affected by the reimbursement policies
imposed by third-party payors, including governments, private insurance plans
and managed care providers and may be affected by regulatory, clinical and
guideline developments and domestic and international trends toward managed
care and healthcare cost containment as well as U.S. legislation affecting
pharmaceutical pricing and reimbursement. Government and others' regulations
and reimbursement policies may affect the development, usage and pricing of
our products. In addition, we compete with other companies with respect to
some of our marketed products as well as for the discovery and development of
new products. We believe that some of our newer products, product candidates
or new indications for existing products, may face competition when and as
they are approved and marketed. Our products may compete against products that
have lower prices, established reimbursement, superior performance, are easier
to administer, or that are otherwise competitive with our products. In
addition, while we routinely obtain patents for our products and technology,
the protection offered by our patents and patent applications may be
challenged, invalidated or circumvented by our competitors and there can be no
guarantee of our ability to obtain or maintain patent protection for our
products or product candidates. We cannot guarantee that we will be able to
produce commercially successful products or maintain the commercial success of
our existing products. Our stock price may be affected by actual or perceived
market opportunity, competitive position, and success or failure of our
products or product candidates. Further, the discovery of significant problems
with a product similar to one of our products that implicate an entire class
of products could have a material adverse effect on sales of the affected
products and on our business and results of operations.

The scientific information discussed in this news release related to our
product candidates is preliminary and investigative. Such product candidates
are not approved by the U.S. Food and Drug Administration (FDA), and no
conclusions can or should be drawn regarding the safety or effectiveness of
the product candidates.
