Data support the therapeutic potential of Amylin's integrated neurohormonal approach to obesity pharmacotherapy
SAN DIEGO, Oct. 1 /PRNewswire-FirstCall/ -- Amylin Pharmaceuticals, Inc.
(Nasdaq: AMLN) today announced that new data for its pipeline obesity
candidates will be presented at the 2008 Annual Scientific Meeting of The
Obesity Society in Phoenix October 3-7. The Obesity Society's annual meeting
is one of the largest and most comprehensive scientific conferences in the
field of obesity.
Amylin will present scientific data through 11 oral and poster
presentations, showcasing progress in the company's obesity pipeline. In
addition to Amylin's lead clinical-stage programs in obesity,
pramlintide/metreleptin and AC2307, new findings will also be presented on
various preclinical programs, including a new Y-family mimetic and Amylin's
peptide hybrid (phybrid) platform. Additional information will be presented
during two corporate-sponsored symposia focused on the emerging peptide
hormone approach to the treatment of obesity and the new science and
therapeutic research that shows promise to reduce the risk of cardiovascular
disease associated with obesity and type 2 diabetes.
"We are excited to present our latest work on the obesity front at this
year's Obesity Society meeting, and will be sharing compelling data that
demonstrates how our programs have the potential to provide significant weight
loss that can be sustained over time," said Daniel Bradbury, president and
chief executive officer at Amylin Pharmaceuticals, Inc. "Our unique
neurohormonal approach to obesity, and our deep expertise in peptide hormones,
enables us to develop drugs that may help regulate how many calories we eat,
burn and store as fat by mimicking the effects of naturally occurring
hormones. Amylin's approach has the potential to achieve significant weight
loss with a reduced risk for side effects that are often seen with other

Obesity is a chronic disease that affects millions of people and is linked
to increased health risk of several medical conditions including type 2
diabetes, high blood pressure, heart disease, stroke, osteoarthritis, sleep
disorders and several types of cancers. According to The Obesity Society,
obesity is the second leading cause of preventable death in the United States.
The total direct and indirect cost attributed to overweight and obesity health
issues exceeds $100 billion in the United States each year. Obesity is also
rapidly becoming a major health problem in all industrialized nations and many
Amylin's Approach to Obesity Research and Development
Physicians and patients seeking prescription medications for weight loss
have limited therapeutic options. New scientific advances have established the
key role of neurohormones in regulating appetite and energy balance, as well
as the importance of studying the interaction among these hormones (within the
brain) to uncover their full therapeutic potential. Amylin scientists
discovered that combination treatment with neurohormones such as amylin and
leptin can produce additive and synergistic weight loss in animal models.
These findings formed the basis for Amylin's innovative integrated
neurohormonal approach to the development of obesity treatments.
About Pramlintide/Metreleptin Combination Treatment
Pramlintide acetate is a synthetic analog of the natural hormone amylin, a
neurohormone secreted by the pancreas that is known to play a role in the
regulation of appetite, food intake and postprandial glucose concentrations.
Pramlintide is the active ingredient in SYMLIN(R) (pramlintide acetate)
injection, which is indicated for use by patients with type 1 and type 2
diabetes who use mealtime insulin and who have failed to achieve desired
glucose control despite optimal insulin therapy. Since launch, over 110,000
patients have been treated with SYMLIN. To date, approximately 8,000
individuals have received pramlintide in clinical trials, including more than
950 in obesity studies. Metreleptin (methionyl recombinant leptin;
r-metHuLeptin) is an analog of human leptin, a neurohormone secreted by fat
cells that plays a fundamental role in the regulation of energy metabolism and
body weight. To date, more than 1,200 overweight or obese individuals have
received metreleptin in clinical trials, several of which were 16 weeks or
longer in duration.
Preclinical and clinical evidence published recently in PNAS, Proceedings
of the National Academy of Sciences of the United States of America,
demonstrates that, when pramlintide and metreleptin are administered in
combination, leptin responsiveness is at least partially restored by amylin
agonism. Experiments in diet-induced obese rats co-administrated with amylin
and leptin resulted in synergistic reductions in food intake (up to 45%) and
body weight (up to 15%), effects considerably greater than with leptin or
amylin treatment alone. Weight loss with amylin/leptin treatment was fat-
specific, and not accompanied by a reduction in lean mass. Translational
clinical research confirms that findings in the non-clinical experiments are
relevant to human obesity and suggest that metreleptin and pramlintide may be
effective partners to pramlintide in the treatment of obesity. The most common
side effects with the pramlintide/metreleptin combination treatment were
injection site adverse events and nausea, which were mostly mild to moderate
and transient in nature.
Important Safety Information for SYMLIN(R)
SYMLIN is not intended for all patients with diabetes. SYMLIN is used with
insulin and has been associated with an increased risk of insulin-induced
severe hypoglycemia, particularly in patients with type 1 diabetes. When
severe hypoglycemia associated with SYMLIN use occurs, it is seen within three
hours following a SYMLIN injection. If severe hypoglycemia occurs while
operating a motor vehicle, heavy machinery, or while engaging in other high-
risk activities, serious injuries may occur. Appropriate patient selection,
careful patient instruction, and insulin dose adjustments are critical
elements for reducing this risk. This information is highlighted in a boxed
warning in the SYMLIN prescribing information for healthcare professionals and
in a medication guide for patients, which will be distributed by pharmacists.
Other adverse events commonly observed with SYMLIN when co-administered
with insulin were mostly gastrointestinal in nature, including nausea, which
was the most frequently reported adverse event. The incidence of nausea was
higher at the beginning of SYMLIN treatment and decreased with time in most
patients. The incidence and severity of nausea are reduced when SYMLIN is
gradually increased to the recommended doses.
