EXENATIDE ONCE MONTHLY SHOWED POSITIVE RESULTS IN PHASE 2 STUDY
Investigational GLP-1 Treatment Improved Glucose Control with Just One Dose per Month
SAN DIEGO, INDIANAPOLIS and WALTHAM, Mass. March 10, 2011 Amylin Pharmaceuticals, Inc.
(Nasdaq: AMLN), Eli Lilly and Company (NYSE: LLY) and Alkermes, Inc. (Nasdaq: ALKS) today announced
positive results from a phase 2 study evaluating the effects of a once-monthly injectable
suspension formulation of exenatide on glycemic control in patients with type 2 diabetes.
The 121-patient, phase 2 study assessed the efficacy, safety and tolerability of three different
doses of exenatide once monthly. It also assessed exenatide once weekly (exenatide extended-release
for injectable suspension, proposed brand name BYDUREON), another investigational type 2 diabetes
therapy. After 20 weeks of treatment (five injections), patients randomized to the exenatide once
monthly treatment arms experienced average reductions in A1C ranging between 1.3 and 1.5 percentage
points from baseline. In the once-weekly BYDUREON treatment arm, the reduction was 1.5 percentage
points. A1C is a measure of average blood sugar over three months.
As innovators in the treatment of type 2 diabetes we brought the first GLP-1 product, BYETTA, to
patients. We are now developing once-weekly and once-monthly formulations of exenatide to expand
patient choices for improving glycemic control, said Christian Weyer, M.D., senior vice president,
research and development, Amylin Pharmaceuticals. Based on the encouraging results of this study,
we plan to proceed with regulatory interactions to outline the next steps for this important
program.
More than 90 percent of patients overall completed the study. The most common adverse events among
the exenatide once monthly treatment groups were headache and nausea. Headache and diarrhea were
most common among the once-weekly BYDUREON group. No major or minor hypoglycemia was reported in
the study.
1
Exenatide once monthly is a new, extended-release formulation of exenatide, the active ingredient
in BYETTA® (exenatide) injection, which is given twice daily. Exenatide once monthly is
based on the same Medisorb® microsphere technology used in BYDUREON.
Study Design
This phase 2, randomized, open-label study included 121 adults with type 2 diabetes who were not
achieving adequate glucose control using diet and exercise alone or with a stable regimen of
metformin, Actos® (pioglitazone), or both. Subjects were randomized to receive either 2
mg weekly subcutaneous injections of BYDUREON or subcutaneous injections of exenatide once monthly
at a low, medium or high dose, each administered once every four weeks, for a total of 20 weeks.
About Diabetes
Diabetes affects nearly 26 million people in the U.S. and an estimated 285 million adults
worldwide.i,ii Approximately 90-95 percent of those affected have type 2 diabetes.
Diabetes costs approximately $174 billion per year in direct and indirect medical
expenses.iii
According to the Centers for Disease Control and Preventions National Health and Nutrition
Examination Survey, approximately 60 percent of people with diabetes do not achieve their target
blood sugar levels with their current treatment regimen.iv In addition, 85 percent of
type 2 diabetes patients are overweight and 55 percent are considered obese.v Data
indicate that weight loss (even a modest amount) supports patients in their efforts to achieve and
sustain glycemic control.vi, vii
About BYETTA® (exenatide) injection
BYETTA was the first glucagon-like peptide-1 (GLP-1) receptor agonist to be approved by the FDA for
the treatment of type 2 diabetes. BYETTA exhibits many of the same effects as the human incretin
hormone GLP-1. GLP-1 improves blood sugar after food intake through multiple effects that work in
concert on the stomach, liver, pancreas and brain.
BYETTA is an injectable prescription medicine that may improve blood sugar (glucose) control in
adults with type 2 diabetes mellitus, when used with a diet and exercise program. BYETTA is not
insulin and should not be taken instead of insulin. BYETTA is not currently recommended to be taken
with insulin. BYETTA is not for people with type 1 diabetes or people with diabetic ketoacidosis.
BYETTA has not been studied in people who have pancreatitis.
BYETTA provides sustained A1C control and low incidence of hypoglycemia when used alone or in
combination with metformin or a thiazolidinedione, with potential weight loss (BYETTA is not a
weight-loss product). BYETTA was approved in the U.S. in April 2005 and has been used by more than
1.5 million patients since its introduction. See important safety information below. Additional
information about BYETTA is available at www.BYETTA.com.
Important Safety Information for BYETTAÒ (exenatide) injection
Based on postmarketing data BYETTA has been associated with acute pancreatitis, including fatal and
non-fatal hemorrhagic or necrotizing pancreatitis. Patients should be observed for signs and
symptoms of pancreatitis after initiation or dose escalation of BYETTA. The risk for getting low
blood sugar is higher if BYETTA is taken with another medicine that can cause low blood sugar, such
as a sulfonylurea. BYETTA should not be used in people who have severe kidney problems and should
be used with caution in people who have had a kidney transplant. Patients should talk with their
healthcare provider if they have severe problems with their
2
stomach, such as delayed emptying of the stomach (gastroparesis) or problems with digesting food.
Antibodies may develop with use of BYETTA. Patients who develop high titers to exenatide could have
worsening or failure to achieve adequate glycemic control. Consider alternative therapy if this
occurs. Severe allergic reactions can happen with BYETTA. There have been no clinical studies
establishing conclusive evidence of macrovascular risk reduction with BYETTA or any other
antidiabetic drug.
The most common side effects with BYETTA include nausea, vomiting, diarrhea, dizziness, headache,
feeling jittery, and acid stomach. Nausea most commonly happens when first starting BYETTA, but may
become less over time.
These are not all the side effects from use of BYETTA. A healthcare provider should be consulted
about any side effect that is bothersome or does not go away.

Information (www.byetta.com/pi) and Medication Guide
(www.byetta.com/mg).
