THOUSAND OAKS, Calif., Oct. 14, 2012

THOUSAND OAKS, Calif., Oct. 14, 2012 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today
announced that it has presented data from several Prolia^® (denosumab)
studies, including data from the open-label extension study of the pivotal
Phase 3 fracture trial, which showed continued increases in bone mineral
density (BMD) and low fracture incidence over six years. These data, and those
from several key studies, were presented at the American Society for Bone and
Mineral Research (ASBMR) 2012 Annual Meeting in Minneapolis from Oct. 12-15,
2012.

"The data presented provide additional insight into the long-term clinical
profile of Prolia," said Sean E. Harper, M.D., executive vice president of
Research and Development at Amgen. "Given the increasing burden of
osteoporosis in an aging population, it is important to see that continued
Prolia therapy may provide ongoing benefit."

SELECTED ABSTRACTS OF INTEREST INCLUDE:
Abstracts are available on the ASBMR website at www.asbmr.org and updated data
have been presented at the meeting.

  oRelationship Between Changes in Bone Mineral Density (BMD) and Incidence
    of Fracture with 6 Years of Denosumab Treatment
    Lead Author: PD Miller, M.D., University of Colorado Health Science Center
    and Colorado Center for Bone Research
    (Abstract No. 1099; Oral Presentation; October 14)

       oNearly all women who received six years of denosumab treatment showed
         gains in BMD at the lumbar spine, total hip or femoral neck: 95
         percent demonstrated gains of greater than six percent at any of
         these sites. The risk for new or worsening vertebral fracture and
         nonvertebral fracture decreased with increasing percentage change in
         total hip BMD over six years.

  oLong-term Denosumab Treatment Maintains Low Incidence of Fracture in
    Postmenopausal Women >75 Years with Osteoporosis
    Lead Author: S. Papapoulos, M.D., Leiden University Medical Center
    (Abstract No. FR0391; Plenary Poster; October 12)

       oDespite the increase in age of the patients during the pivotal Phase
         3 fracture study extension, denosumab treatment continued to be
         associated with a low incidence of new vertebral, nonvertebral and
         hip fractures.
       oThe incidence of fractures in patients > 75 years in the study
         extension was similar to what was originally observed in women older
         than 75 years in the original pivotal Phase 3 fracture study.

  oEffects of 5 Years of Denosumab on Bone Histology and Histomorphometry:
    FREEDOM Study Extension
    Lead Author: JP Brown, M.D., Laval University and CHUQ
    (Abstract No. 1134; Oral Presentation; October 14)

       oDenosumab treatment through five years resulted in normal bone
         quality with reduced bone turnover, consistent with its mechanism of
         action.

About Osteoporosis
Osteoporosis, which causes more than 2 million bone breaks each year, is a
growing concern among health professionals as more than 40 million people are
either living with, or at risk for developing, the disease. The World Health
Organization has officially declared osteoporosis a public health crisis,
while the International Osteoporosis Foundation urges governments worldwide to
make osteoporosis a healthcare priority.

In the United States (U.S.), the number of fractures due to osteoporosis is
expected to rise to more than 3 million by 2025.^1 In 2000, the number of
osteoporotic fractures in Europe was estimated at 3.79 million, of which
890,000 were hip fractures.^2 Since 2001, the incidence of hip fractures in
European countries has risen significantly.^3

In 2005, osteoporosis-related fractures were responsible for an estimated $19
billion in cost in the U.S., and this cost is expected to rise to
approximately $25 billion by 2025.^1 [ ]The direct medical cost of
osteoporotic fractures in Europe is expected to rise from €31.7 billion in
2000 to €76.7 billion in 2050.^2

About Prolia
Prolia is the first approved therapy that specifically targets RANK Ligand, an
essential regulator of osteoclasts (the cells that break down bone).

Prolia is approved in the U.S. for the treatment of postmenopausal women with
osteoporosis at high risk for fracture, defined as a history of osteoporotic
fracture, or multiple risk factors for fracture; or patients who have failed
or are intolerant to other available osteoporosis therapy.

Prolia is also indicated as a treatment to increase bone mass in women at high
risk for fracture receiving adjuvant aromatase inhibitor therapy for breast
cancer and in men at high risk for fracture receiving androgen deprivation
therapy for nonmetastatic prostate cancer. In these patients with prostate
cancer, Prolia reduced the incidence of vertebral fractures.

Prolia is indicated for treatment to increase bone mass in men with
osteoporosis at high risk for fracture, defined as a history of osteoporotic
fracture, or multiple risk factors for fracture; or patients who have failed
or are intolerant to other available osteoporosis therapy.

Prolia is approved in the European Union (EU) for the treatment of
osteoporosis in postmenopausal women at increased risk of fractures, and for
the treatment of bone loss associated with hormone ablation in men with
prostate cancer at increased risk of fractures.

Prolia is approved in the U.S., Canada, Australia and in all 27 EU member
states as well as in Norway, Iceland and Liechtenstein. Applications in the
rest of the world are pending.

Prolia is administered as a single subcutaneous injection of 60 mg once every
six months. For further information on Prolia, including prescribing
information and medication guide, please visit: www.prolia.com.

Important U.S. Safety Information
Prolia is contraindicated in patients with hypocalcemia. Pre-existing
hypocalcemia must be corrected prior to initiating Prolia. Prolia is
contraindicated in women who are pregnant and may cause fetal harm. Prolia is
contraindicated in patients with a history of systemic hypersensitivity to any
component of the product. Patients receiving Prolia should not receive XGEVA^®
(denosumab), as both Prolia and XGEVA contain the same active ingredient,
denosumab.

Hypocalcemia may worsen with the use of Prolia, especially in patients with
severe renal impairment. All patients should be adequately supplemented with
calcium and vitamin D. In the pivotal Phase 3 study of women with
postmenopausal osteoporosis (n=7808), serious infections leading to
hospitalizations were reported more frequently in the Prolia-treated patient
group. Serious skin infections, as well as infections of the abdomen, urinary
tract and ear, were more frequent in patients treated with Prolia. Patients
should be advised to seek prompt medical attention if they develop signs or
symptoms of severe infection, including cellulitis. Endocarditis was reported
more frequently in the Prolia-treated patient group. Epidermal and dermal
adverse events such as dermatitis, rashes and eczema have been reported.
Discontinuation of Prolia should be considered if severe symptoms develop.

In clinical trials in women with postmenopausal osteoporosis, Prolia resulted
in significant suppression of bone remodeling. The significance of these
findings is unknown. The long-term consequences of the degree of suppression
of bone remodeling observed with Prolia may contribute to adverse outcomes
such as osteonecrosis of the jaw (ONJ), atypical fractures and delayed
fracture healing. ONJ and atypical femoral fractures have been reported in
patients with Prolia. Patients should be monitored for these adverse outcomes.
The most common adverse reactions (>5 percent and more common than placebo) in
patients with postmenopausal osteoporosis were back pain, pain in extremity,
musculoskeletal pain, hypercholesterolemia and cystitis. The most common
adverse reactions in men with osteoporosis were back pain, arthralgia and
nasopharyngitis. Pancreatitis has also been reported with Prolia in patients
with osteoporosis. The most common (per patient incidence >10 percent) adverse
reactions reported with Prolia in patients with bone loss receiving androgen
deprivation therapy for prostate cancer or adjuvant aromatase inhibitor
therapy for breast cancer are arthralgia and back pain. Pain in extremity and
musculoskeletal pain have also been reported in clinical trials.

The extent to which Prolia is present in seminal fluid is unknown. For men
treated with Prolia, there is a potential for fetal exposure if the sexual
partner is pregnant. While the risk is likely to be low, patients should be
advised of this potential risk.

Important EU Safety Information
The most common adverse reactions with Prolia were urinary tract infection,
upper respiratory tract infection, sciatica, cataracts, constipation, rash and
pain in extremity. The most serious adverse reactions were those of skin
infections, predominantly cellulitis, reported more commonly in the Prolia
group compared with placebo (0.4 percent vs. 0.1 percent) in postmenopausal
osteoporosis studies. In breast and prostate cancer studies, serious adverse
reactions of skin infection were similar in the Prolia and placebo groups (0.6
percent vs. 0.6 percent). In the Phase 3 placebo-controlled clinical trial in
patients with prostate cancer receiving ADT, an imbalance in cataract adverse
events was observed with Prolia compared with placebo (4.7 percent vs. 1.2
percent placebo). No imbalance in cataract adverse events was observed in
postmenopausal women with osteoporosis or in women undergoing aromatase
inhibitor therapy for nonmetastatic breast cancer.

Prolia may lead to hypocalcaemia. Hypocalcaemia must be corrected by adequate
intake of calcium and vitamin D before initiating therapy. ONJ has been
reported rarely in clinical studies in patients receiving denosumab at a dose
of 60 mg every 6 months for osteoporosis. In the post-marketing setting, rare
events of drug-related hypersensitivity have been reported in patients
receiving Prolia.

Denosumab Commercialization Collaborations
In July 2009, Amgen and GlaxoSmithKline announced a collaboration agreement to
jointly commercialize Prolia for postmenopausal osteoporosis in Europe,
Australia, New Zealand and Mexico once the product is approved in these
countries. Amgen will commercialize Prolia's postmenopausal osteoporosis and
potential oncology indications in the U.S. and Canada and for all oncology
indications in Europe and in other specified markets.

In addition, GlaxoSmithKline will register and commercialize denosumab for all
indications in countries where Amgen does not currently have a commercial
presence, including China, India and South Korea but excluding Japan. The
structure of the collaboration allows Amgen the option of an expanded role in
commercialization in both Europe and certain emerging markets in the future.

Amgen and Daiichi Sankyo Company, Limited have a collaboration and license
agreement for the development and commercialization of denosumab in Japan.

Forward Looking Statements
This news release contains forward-looking statements that are based on
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 most
recent 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 Oct. 14, 2012 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 relating to new
indications for our products is preliminary and investigative and is not part
of the labeling approved by the U.S. Food and Drug Administration (FDA) for
the products. The products are not approved for the investigational use(s)
discussed in this news release, and no conclusions can or should be drawn
regarding the safety or effectiveness of the products for these uses. Only
the FDA can determine whether the products are safe and effective for these
use(s). Healthcare professionals should refer to and rely upon the
FDA-approved labeling for the products, and not the information discussed in
this news release.
