Study Shows Neulasta Reduced the Incidence of Febrile Neutropenia in Patients
With Colorectal Cancer Receiving FOLFOX or FOLFIRI and Bevacizumab
THOUSAND OAKS, Calif.,  Jan. 26, 2013  /PRNewswire/ -- Amgen (NASDAQ:AMGN)
announced today results from Pegfilgrastim and Anti-VEGF Evaluation Study
(PAVES), a Phase 3 trial which evaluated Neulasta® (pegfilgrastim) in 845
patients receiving FOLFOX or FOLFIRI and bevacizumab for the first-line
treatment of locally-advanced or metastatic colorectal cancer. FOLFOX and
FOLFIRI are two of the most commonly used chemotherapy regimens for colorectal

The study met its primary endpoint, with Neulasta significantly reducing the
incidence of febrile neutropenia. Febrile neutropenia is a low white blood cell
count accompanied by a fever.1  In the study, the incidence of grade 3 or 4
febrile neutropenia in patients receiving Neulasta across the first four cycles
of chemotherapy was 2.4 percent compared to 5.7 percent in the placebo group
(OR=0.41,  p=0.014). A similar incidence of grade 3 or higher adverse events was
seen in both arms of the trial (28 percent placebo; 27 percent Neulasta).

"This analysis showed that PAVES met its primary endpoint, with Neulasta
significantly reducing the incidence of febrile neutropenia in patients with
colorectal cancer," said  Sean E. Harper, M.D., executive vice president of
Research and Development at Amgen. "In addition to providing new data on
Neulasta, we believe PAVES will provide valuable information to the oncology
community on commonly-used chemotherapy regimens."

Full results will be presented on  Saturday, Jan. 26  during the 2013
Gastrointestinal Cancers Symposium, General Poster Session C (C1) by  Tamas
Pinter, M.D., the PAVES principal investigator, Aladar Korhaz Hospital,
Onkoradiologiai Osztaly, Gyor,  Hungary  (Late Breaking Abstract No. 445).  

Follow-up results of PAVES looking at additional endpoints, including mature
data on overall survival, overall response rate, time to progression and
progression-free survival, will be presented at a future date.   

About PAVES  

PAVES is a Phase 3, randomized, double-blind, placebo-controlled trial
evaluating Neulasta in 845 patients receiving FOLFOX or FOLFIRI and bevacizumab
for the first-line treatment of locally-advanced or metastatic colorectal
cancer. The trial was multicenter and multinational. All patients received
treatment with either FOLFOX or FOLFIRI plus bevacizumab and were randomized to
one of two treatment arms that also received either placebo or 6 mg of Neulasta
at least 24 hours after each cycle of chemotherapy. The primary endpoint was the
incidence of grade 3 or 4 febrile neutropenia during the first four cycles. The
study was not designed to define the febrile neutropenia rate of FOLFOX or
FOLFIRI plus bevacizumab. Other endpoints include overall response rate,
progression-free survival, overall survival, time to progression and adverse

About Febrile Neutropenia

One of the most common side effects of myelosuppressive chemotherapy is a low
white blood cell count.2  An abnormally low level of neutrophils, an important
infection-fighting white blood cell, is called neutropenia.2  The fewer
neutrophils a patient has - and the longer the neutrophil count remains low -
the greater the risk of developing a potentially serious infection.2, 3

Febrile neutropenia is neutropenia complicated by a fever.1  Fever is frequently
a sign of infection and, in patients receiving myelosuppressive chemotherapy, it
can sometimes be the only sign.2  Febrile neutropenia is a medical emergency and
is associated with several potential downstream consequences.2, 4

About Neulasta  

Neulasta was approved by the U.S. Food and Drug Administration (FDA) in 2002 to
decrease the incidence of infection, as manifested by febrile neutropenia, in
patients with nonmyeloid malignancies receiving myelosuppressive anticancer
drugs associated with a clinically significant incidence of febrile
neutropenia.5  Neulasta is not indicated for the mobilization of peripheral
blood progenitor cells for hematopoietic stem cell transplantation.

Important Safety Information

Do not administer Neulasta to patients with a history of serious allergic
reactions to pegfilgrastim or Filgrastim.

Fatal splenic rupture can occur. Evaluate for splenomegaly or splenic rupture in
patients with left upper abdominal or shoulder pain. Acute respiratory distress
syndrome (ARDS) can occur. Evaluate for ARDS in patients who develop fever, lung
infiltrates, or respiratory distress. Discontinue Neulasta in patients with
ARDS. Serious allergic reactions, including anaphylaxis, can occur. Permanently
discontinue Neulasta in patients with serious allergic reactions. Severe and
sometimes fatal sickle cell crises have been reported.

Most common adverse reactions (≥ 5% difference in incidence) in
placebo-controlled clinical trials are bone pain and pain in extremity.

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 
Jan. 26, 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 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 uses. Healthcare
professionals should refer to and rely upon the FDA-approved labeling for the
products, and not the information discussed in this news release.
