BYETTA(R) Treatment for Three and a Half Years Associated with Sustained Improvements in Blood Glucose Control in People with Type 2 Diabetes

    Chicago (ots/PRNewswire) -

    - Study also showed added benefits of reductions in cardiovascular risk factors and progressive weight loss -

    Amylin Pharmaceuticals, Inc. (Nasdaq: AMLN) and Eli Lilly and Company (NYSE: LLY) today announced results from a study that showed BYETTA(R) (exenatide) injection in conjunction with common oral medication sustained improvements in blood sugar levels through three and a half years of therapy. These findings were presented at the 67th Annual Scientific Sessions of the American Diabetes Association (ADA) in Chicago.

    In this study, 151 people with type 2 diabetes who had taken part in a 30-week placebo-controlled trial were followed in open-label extension studies for three and a half years. Participants using exenatide (10 mcg) twice daily with common oral medication (metformin and/or a sulphonylurea) showed sustained reductions in blood sugar as measured by HbA1c (-0.8 +/- 0.1 percent) and fasting blood glucose (-1.3 +/- 0.2 mmol/L [-24 +/- 4 mg/dL]), consistent with findings from previous studies.

    People with type 2 diabetes are at increased risk for various cardiovascular problems, including high blood pressure and cholesterol. Secondary study endpoints examined the potential benefits of exenatide for weight loss and cardiovascular risk factor reduction over three and a half years. Treatment with exenatide in combination with common oral medications was associated with progressive weight loss (-5.3 +/- 0.5 kg [-11.7 +/- 1.1 lbs]), improved triglyceride levels (0.50 +/- 0.14 mmol/L [-44.4 +/- 12.1 mg/dL] or 12 percent), and lower systolic and diastolic blood pressure (-3.5 +/- 1.2 mmHg or 2 percent and -3.3 +/- 0.8 mmHg or 4 percent, respectively). Results also showed an increase in HDL, or "good" cholesterol levels after three and a half years (+0.22 +/- 0.02 mmol/L [+8.5 +/- 0.6 mg/dL] or 24 percent) and a decrease in LDL, or "bad" cholesterol levels (-0.31 +/- 0.07 mmol/L [-11.8 +/- 2.9 mg/dL] or 6 percent).(1,2)

    "The sustained improvements in blood glucose control seen with exenatide are well documented," said David Kendall, Executive Director, Medical Affairs, Amylin Pharmaceuticals, Inc. "The secondary study endpoints suggesting that exenatide may have effects on cardiovascular disease risk factors provide interesting areas for further study."

    Exenatide was generally well-tolerated in this study, and the side effects were consistent with those seen in previous studies. In clinical trials and post-approval adverse event reports, the most common side effect is nausea, most of which was mild to moderate, affecting approximately half of patients and usually decreases over time.

    About BYETTA(R) (exenatide) injection

    BYETTA is the first in a class of drugs for the treatment of type 2 diabetes called incretin mimetics. BYETTA exhibits many of the same effects as the human incretin hormone glucagon like peptide-1 (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 approved in the European Union as adjunctive therapy to improve blood sugar control in patients with type 2 diabetes who have not achieved adequate glycaemic control on maximally tolerated doses of metformin and/or a sulphonylurea, two common oral diabetes medications. BYETTA provides sustained HbA1c control, low incidence of hypoglycaemia when used with metformin and progressive weight loss.

    Important Safety Information for BYETTA(R) (exenatide) injection

    In clinical studies, the most common side effects were hypoglycaemia (low blood sugar) when taken with a sulphonylurea, nausea (feeling sick), vomiting and diarrhea. For the full list of all side effects reported with BYETTA, see the Package Leaflet. BYETTA should not be used in people who may be hypersensitive (allergic) to exenatide or any of the other ingredients.

    About Diabetes

    Diabetes affects an estimated 246 million adults worldwide and more than 48 million in Europe.(3,4) Approximately 90 to 95 percent of those affected by type 2 diabetes, a condition characterized by failure of the pancreatic beta cells to adequately respond to the increased demands for insulin that occur as a result of obesity-related insulin resistance.(5) Type 2 diabetes usually occurs in adults over the age of 40, but is increasingly common in younger people.(4) In virtually every developed society, diabetes is ranked among the leading causes of blindness, renal failure and lower limb amputation, as well as death through its effects on cardiovascular disease (70-80 percent of people with diabetes die of cardiovascular disease).(6) The calculated estimates of the costs of diabetes care in Europe amount to 42.8 billion International Dollars per year.(7)
