SAN DIEGO, CA, INDIANAPOLIS, IN and CAMBRIDGE, MA, March 24 /PRNewswire-FirstCall/ -- Amylin Pharmaceuticals, Inc. (NASDAQ:AMLN), Eli Lilly and Company (NYSE:LLY) and Alkermes, Inc. (NASDAQ:ALKS) today announced that, following discussions with the U.S. Food and Drug Administration (FDA), a long-term comparator clinical study of a long-acting release (LAR) formulation of BYETTA(R) (exenatide) injection in patients with type 2 diabetes has been initiated. This study is designed to generate the type of safety and efficacy data that could form the basis of a New Drug Application (NDA). The 30-week open-label, noninferiority study will assess whether once-weekly exenatide LAR is at least as effective in improving glucose control as twice-daily BYETTA. Approximately 300 subjects with type 2 diabetes who are not achieving adequate glucose control using diet and exercise with or without the use of oral antidiabetic agents will be randomized to one of two treatment groups. Subjects randomized to the exenatide LAR group will receive once-weekly subcutaneous injections of a single strength of exenatide LAR. Subjects randomized to the comparison group will receive twice-daily injections of 10 micrograms of BYETTA. Endpoints include change in hemoglobin A1C (a standard measure of glucose control), fasting blood glucose, body weight, and safety parameters. All participants who complete the randomized portion of the study will have the opportunity to continue in an extension study and receive once-weekly exenatide LAR. In parallel with clinical activities, manufacturing process development and scale-up activities are underway. The material for this study is being manufactured at development scale, and the Companies are working to determine the overall manufacturing strategy. In December 2005, Amylin announced that it purchased a facility for the commercial production of exenatide LAR and expects to finalize the commercial manufacturing process for exenatide LAR by late 2008. 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. Amylin, Lilly, and Alkermes are working together to develop a sustained release, subcutaneous injection of exenatide for the treatment of type 2 diabetes based on Alkermes' proprietary Medisorb(R) technology. Exenatide LAR has not been approved by the FDA for marketing in the United States. 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 improve blood sugar.(1) About Incretin Mimetics Incretin mimetics is a new class of therapeutic agents in the fight against diabetes. An incretin mimetic works to mimic the antidiabetic 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 90-95 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 A1C levels (less than 7.0 percent according to American Diabetes Association guidelines(4)) with their current treatment regimen.(5) Important Safety Information for BYETTA(TM) (exenatide) injection BYETTA(TM) (exenatide) injection improves 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 when 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.
