BYDUREONtm REPLY SUBMITTED to FDA
New PDUFA Action Date Expected Within 14 Days, per FDA Guidelines
SAN DIEGO, INDIANAPOLIS, and WALTHAM, Mass. - July 28, 2011 - Amylin
Pharmaceuticals, Inc. (Nasdaq: AMLN), Eli Lilly and Company (NYSE: LLY) and
Alkermes, Inc. (Nasdaq: ALKS) today announced that the companies have submitted
their reply to a complete response letter issued in October 2010 by the U.S.
Food and Drug Administration (FDA) regarding BYDUREONtm (exenatide
extended-release for injectable suspension), an investigational medication for
type 2 diabetes. The companies expect to receive an updated Prescription Drug
User Fee Act (PDUFA) action date from the FDA within the next two weeks. Since
the reply included additional data, it will likely be categorized as a Class 2
resubmission requiring up to six months for review.
The reply submission includes results from the recently completed thorough QT
(tQT) study, which showed that exenatide, at and above therapeutic levels, did
not prolong the corrected QT interval in healthy individuals as defined by the
FDA's published guidance. The reply also contains results from the DURATION-5
study, which compared the commercial formulation of BYDUREON to BYETTA®
(exenatide) injection. Additionally, it includes an update of safety
information from studies ongoing or completed since the last submission, as is
standard practice in a complete response scenario.
"We worked expeditiously to complete the requested tQT study and consulted with
the FDA throughout the process," said Christian Weyer, M.D., senior vice
president, research and development, Amylin Pharmaceuticals. "We are confident
that the study results and our detailed submission have addressed the
requirements outlined by the FDA, and we remain committed to making BYDUREON
available to patients in the U.S. as soon as possible."
BYDUREON is the proposed brand name for exenatide extended-release for
injectable suspension. It is an investigational medication for type 2 diabetes
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, 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 U.K. 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., 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.
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. In addition, 85 percent of type 2 diabetes patients are
overweight and 55 percent are considered obese. Data indicate that weight loss
(even a modest amount) supports patients in their efforts to achieve and
sustain glycemic control.,
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.
For additional important safety information about BYETTA, please see the full
Prescribing Information (www.byetta.com/pi) and Medication Guide (
www.byetta.com/mg).
