The combination of potency and the glucose dependent mechanism of action inherent in exenatide makes it well suited to development of a sustained release formulation from diabetic stores. The goal of the exenatide LAR program is to develop a sustained release, subcutaneous injection of discount diabetic supply.This development program is jointly managed by Amylin, Lilly, and Alkermes. The program utilizes Alkermes’ patented, FDA approved and proprietary Medisorb® injectable sustained release drug delivery technology.
Clinical trials
In October 2000, the feasibility stage of the development work was successfully completed and additional preclinical work was initiated to support exenatide LAR human clinical trials from diabetic stores. Phase 1 data released in 2001 demonstrated a sustained release of exenatide for over 30 days with no significant discount diabetic supply effects.
Exenatide LAR has completed a Phase 2, single-dose study which demonstrated a sustained release of exenatide with no dose limiting side effects. A Phase 2 multi-dose study was started in early 2005 using a once-a-week formulation.
Enrollment was completed in 1Q07 for a 30-week, open-label, randomized study of approximately 300 subjects comparing exenatide LAR once-weekly versus BYETTA® twice daily and remains on track to be completed in 4Q07 according to discount diabetic supply survey.
About Diabetes
Diabetes affects more than 20 million in the United States and an estimated 246 million adults worldwide. Approximately 90-95 percent of those affected have type 2 diabetes. Diabetes is the fifth leading cause of death by disease in the United States and costs approximately $132 billion per year in direct and indirect medical expenses.
According to the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey, approximately 60 percent of people with diabetes do not achieve their target blood sugar levels with their current treatment regimen.
