"SymlinPen 120 and SymlinPen 60 offer patients improved convenience and accuracy," said Daniel M. Bradbury, President and CEO, Amylin Pharmaceuticals. "For people with diabetes using mealtime insulin, the addition of SYMLIN can enhance glucose control with the potential for weight loss."

SymlinPen(TM) 60 features fixed dosing to deliver 15, 30, 45, or 60 micrograms per dose. SymlinPen(TM) 120 features fixed dosing to deliver 60 or 120 micrograms per dose. Both pen-injector devices can be conveniently stored at room temperature not to exceed 86 degrees F (30 degrees C) after first use. The pens are expected to be available to patients by December 2007.

"Not Approvable" Letter Received for SYMLIN Use with Basal Insulin Alone

Amylin also announced today that the FDA has issued a "Not Approvable" letter for SYMLIN use with basal insulin (without mealtime insulin) in patients with type 2 diabetes who have not achieved desired glucose control. SYMLIN is currently approved in the U.S. for patients with type 2 or type 1 diabetes who use mealtime insulin and need improved glucose control.

"SYMLIN remains an important therapeutic option for people with diabetes who use mealtime insulin therapy," Bradbury added. "We will initiate discussions with the FDA to clarify their response for its use with basal insulin alone."

About SYMLIN

SYMLIN is the first and only amylin mimetic for use in patients with diabetes treated with mealtime insulin. SYMLIN is a synthetic analog of human amylin, a naturally occurring hormone that is made in the beta cells of the pancreas, the same cells that make insulin. In patients with type 2 diabetes who use insulin, and in patients with type 1 diabetes, those cells in the pancreas are either damaged or destroyed, resulting in reduced secretion of both insulin and amylin after meals. The use of SYMLIN contributes to glucose control after meals.

Important Safety Information

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. 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.
