Amylin Pharmaceuticals, Inc. (Nasdaq: AMLN), Eli Lilly and
Company (NYSE: LLY) and Alkermes, Inc. (Nasdaq: ALKS) today
announced that the U.S. Food and Drug Administration (FDA) has
acknowledged the companies’ BYDUREON™ (exenatide extended-release
for injectable suspension) resubmission. The FDA has categorized it
as a Class 2 resubmission requiring up to six months for review and
assigned a new Prescription Drug User Fee Act (PDUFA) action date
of January 28, 2012. BYDUREON is an investigational medication for
type 2 diabetes.
“If approved, we believe BYDUREON will be an important new
option for type 2 diabetes patients, as the first once-weekly
treatment available in the U.S.,” said Christian Weyer, M.D.,
senior vice president, research and development, Amylin
Pharmaceuticals. “We will continue to work with the FDA through
this stage of the review process.”
BYDUREON is the proposed brand name for exenatide
extended-release for injectable suspension. It is designed to
deliver continuous therapeutic levels of exenatide in a single
weekly dose. BYDUREON is a once-weekly formulation of exenatide,
the active ingredient in BYETTA® (exenatide) injection, which has
been available in the U.S. since June 2005 and is used in more than
70 countries worldwide to improve glycemic control in adults with
type 2 diabetes. BYDUREON and BYETTA belong to the glucagon-like
peptide-1 (GLP-1) receptor agonist class of medications.
The New Drug Application (NDA) for BYDUREON was submitted in May
2009. It is based on safety and efficacy data from the DURATION
clinical trial program and the BYETTA NDA, as well as
post-marketing experience with BYETTA. The FDA issued complete
response letters to the companies in March 2010 and October
2010.
BYDUREON received marketing authorization in the European Union
in June 2011. It is available in the UK and will launch in other
major European countries as soon as possible.
About Diabetes
Diabetes affects nearly 26 million people in the U.S. and an
estimated 347 million adults worldwide.1,2 Approximately 90-95
percent of those affected have type 2 diabetes. In the U.S.,
diabetes costs more than $174 billion per year in direct and
indirect medical expenses.3
According to the Centers for Disease Control and Prevention’s
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.4 In addition, 85
percent of type 2 diabetes patients are overweight and 55 percent
are considered obese.5 Data indicate that weight loss (even a
modest amount) supports patients in their efforts to achieve and
sustain glycemic control.6,7
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 in Europe in November 2006 and has been used by more than 1.8
million patients since its introduction. See important safety
information below. Additional information about BYETTA is available
at www.BYETTA.com.
Important Safety Information for BYETTA®
(exenatide) injection
Based on post-marketing 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 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.
