About Osteoporosis
Postmenopausal osteoporosis (PMO) affects many women after menopause^1-2 and
is a disease that weakens bones over time, making them thinner and more likely
to break.^2

In PMO, bone-removing cells get rid of bone at a rate that is too fast.^3 This
puts postmenopausal women with osteoporosis at risk for breaking a bone.^3
Such a break, or fracture, may be a life-changing event. About half of all
women over age 50 will have an osteoporosis-related fracture, and once that
happens, the chances of another are much higher.^4 According to the National
Osteoporosis Foundation, women who have suffered a hip fracture are at a
four-times greater risk of a second one.^4

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.

Osteoporosis-related fractures are responsible for an estimated $19 billion in
costs annually in the U.S., and are expected to rise to approximately $25
billion by 2025.^5 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.^6

About Romosozumab
Romosozumab is a bone-forming agent that inhibits sclerostin.It is currently
being studied for its potential to reduce fracture risk in an extensive global
Phase 3 program. This program includes two pivotal studies evaluating
romosozumab against both placebo and active comparator in more than 10,000
women with postmenopausal osteoporosis.Romosozumab is being developed in
collaboration with UCB. 

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:

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,

Clinically significant hypersensitivity including anaphylaxis has been
reported with Prolia^®. If an anaphylactic or other clinically significant
allergic reaction occurs, initiate appropriate therapy and discontinue further
use of Prolia^®. 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 (≥1 percent) adverse reactions in clinical trials with Prolia
in postmenopausal women with osteoporosis and breast or prostate cancer
patients receiving hormone ablation were pain in extremity, urinary tract
infection, upper respiratory tract infection, sciatica, cataracts,
constipation, rash and eczema. Skin infections (predominantly cellulitis)
leading to hospitalisation were 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 androgen deprivation therapy (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 rarely lead to hypocalcaemia. Prolia is contraindicated in patients
with hypocalcaemia, and pre-existing hypocalcaemia must be corrected by
adequate intake of calcium and vitamin D before initiating therapy. Patients
with severe renal impairment or receiving dialysis are at greater risk of
developing hypocalcaemia. In the post-marketing setting, rare cases of severe
symptomatic hypocalcaemia have been reported in patients at increased risk of
hypocalcaemia. Osteonecrosis of the jaw (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 osteoporosis clinical trial program, atypical
femoral fractures were reported rarely in patients treated with Prolia. In the
post-marketing setting, rare events of drug-related hypersensitivity,
including anaphylactic reaction, have been reported in patients receiving
Prolia. Hypersensitivity to the active substance or any of the excipients is a
contraindication for Prolia.

Prolia is not recommended for use in pregnant women.

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 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 Oct. 4, 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 product liability claims. If we fail to meet the compliance
obligations in the corporate integrity agreement between us and the U.S.
government, we could become subject to significant sanctions. 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

In addition, sales of our products are affected by the reimbursement policies
imposed by third-party payers, 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.
