Amylin Pharmaceuticals Announces FDA Approval of SYMLIN(R) for Insulin-Using Type 2 and Type 1 Diabetes For Use With Insulin to Improve Glucose Control SAN DIEGO, March 16 /PRNewswire-FirstCall/ -- Amylin Pharmaceuticals, Inc. (NASDAQ:AMLN) today announced that the U.S. Food and Drug Administration (FDA) has approved SYMLIN(R) (pramlintide acetate) injection to be used in conjunction with insulin to treat diabetes. SYMLIN is to be used at mealtime in patients with type 2 or type 1 diabetes who have failed to achieve desired glucose control despite optimal insulin therapy. SYMLIN will be commercially available in approximately 90 days. "The approval of SYMLIN, a first-in-class therapy, is a major milestone for Amylin Pharmaceuticals. It is the result of 18 years of research in diabetes," said Ginger L. Graham, President and CEO of Amylin Pharmaceuticals, Inc. "This extensive development program has resulted in prescribing information for SYMLIN that we believe is an excellent tool to introduce SYMLIN to the diabetes community." Clinical studies demonstrate that SYMLIN, a self-administered injection given prior to meals, helps patients achieve lower blood glucose (sugar) after meals, leading to less fluctuation during the day, and better long-term glucose control (A1C) compared to patients taking insulin alone. In these studies, patients used less mealtime insulin and also had a reduction in body weight compared to patients taking insulin alone. SYMLIN was studied in over 5300 individuals in the clinical program that led to approval. "SYMLIN provides a new option for many patients who, despite their best efforts with insulin therapy, continue to struggle to achieve their glucose control targets. These patients often experience weight gain and continued high blood sugar after meals," said Robert E. Ratner, MD, an investigator for SYMLIN clinical studies, Vice President for Scientific Affairs, MedStar Research Institute and Professor of Medicine at the Georgetown University Medical School. "The science behind SYMLIN has improved our understanding of the physiology of diabetes and has provided a welcome new tool for insulin users." 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. Amylin will provide educational programs for physicians, diabetes care teams, and patients to help ensure appropriate administration and patient selection. In addition, the company plans to conduct a small pediatric study and a two-year open-label study to evaluate SYMLIN use in clinical practice and assess the effectiveness of its education programs. About SYMLIN SYMLIN is an antihyperglycemic drug for use in patients with diabetes treated with 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. Healthcare professionals and people with diabetes may obtain more information, including the complete prescribing information and the medication guide, at http://www.symlin.com/. About Diabetes Diabetes is a large and growing market in the United States, affecting over 18 million Americans and growing at three times the rate of population growth. Approximately 4.5 million patients with diabetes use insulin. Diabetes is the sixth leading cause of death in the United States. Diabetes is a complex metabolic disease manifesting with a defect in the beta cells in the pancreas, resulting in a deficiency of both insulin and amylin secretion. Poor control of blood sugar may result in severe long-term complications such as kidney failure, nerve damage, blindness, amputation and cardiovascular disease.
