Supplemental New Drug Application for BYETTA Submitted to FDA for Use With TZDs

SAN DIEGO and INDIANAPOLIS, March 1 (HSMN NewsFeed) -- Amylin Pharmaceuticals, Inc. (Nasdaq: AMLN ) and Eli Lilly and Company (NYSE: LLY ) announced the recent submission of a supplemental New Drug Application to the Food and Drug Administration (FDA) to seek approval for expanded use of BYETTA® (exenatide) injection as add-on therapy to a common class of oral diabetes medication called thiazolidinediones (or TZDs), in people with type 2 diabetes who are not achieving acceptable blood sugar control.

BYETTA was approved by the FDA in April 2005 for the treatment of type 2 diabetes as add-on therapy in patients who are not achieving acceptable blood sugar control despite using the commonly prescribed diabetes medications metformin, a sulfonylurea or a combination of both.

About BYETTA

BYETTA is the first in a new class of drugs for the treatment of type 2 diabetes called incretin mimetics and exhibits many of the same effects as the human incretin hormone glucagon-like peptide-1 (GLP-1). GLP-1, secreted in response to food intake, has multiple effects on the intestine, liver, pancreas and brain that work in concert to regulate blood sugar.(1)

About Incretin Mimetics

Incretin mimetics is a new class of treatment in the fight against diabetes. An incretin mimetic works to mimic the anti-diabetic or glucose-lowering actions of naturally occurring human hormones called incretins. These actions include stimulating the body's ability to produce insulin in response to elevated levels of blood sugar, inhibiting the release of a hormone called glucagon following meals, slowing the rate at which nutrients are absorbed into the bloodstream and reducing food intake. BYETTA is the first FDA-approved agent of this new class of medications.

About Diabetes

Diabetes affects an estimated 194 million adults worldwide(2) and more than 20 million in the United States.(3) Approximately 90 to 95 percent of those affected have type 2 diabetes, a condition where the body does not produce enough insulin and/or the cells in the body do not respond normally to insulin.(3) Diabetes is the sixth leading cause of death by disease in the United States(3) and costs approximately $132 billion per year in direct and indirect medical expenses. Type 2 diabetes usually occurs in adults over the age of 40, but is increasingly common in younger people.(3)

According to the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey, approximately 60 percent of diabetes patients do not achieve target hemoglobin A1C levels (less than 7 percent according to ADA guidelines(4)) with their current treatment regimen.(5)

Important Safety Information for BYETTA (exenatide) injection

BYETTA (exenatide) injection improved blood sugar control in patients with type 2 diabetes who are taking metformin, a sulfonylurea, or both. BYETTA is not a substitute for insulin in patients whose diabetes requires insulin treatment. BYETTA is not recommended for use in patients with severe problems digesting food or those who have severe disease of the stomach or kidney. BYETTA has not been studied in children or pregnant women.

When BYETTA is used with a medicine that contains a sulfonylurea, low blood sugar (hypoglycemia) is a possible side effect. To reduce this possibility, the dose of sulfonylurea medicine may need to be reduced while using BYETTA. Other common side effects with BYETTA include nausea, vomiting, diarrhea, dizziness, headache, feeling jittery, and acid stomach. Nausea is most common with first starting BYETTA, but decreases over time in most patients. BYETTA may reduce appetite, the amount of food eaten, and body weight. No changes in dose are needed for these side effects. These are not all the side effects with BYETTA. A health care provider should be consulted about any side effect that is bothersome or does not go away.
