BYDUREON Would Be First Once-Weekly Treatment for Adults with Type 2 Diabetes
INDIANAPOLIS, SAN DIEGO and WALTHAM, Mass., April 15, 2011 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY), together with Amylin Pharmaceuticals, Inc. (Nasdaq: AMLN) and Alkermes, Inc. (Nasdaq: ALKS), announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion recommending approval of exenatide 2 mg powder and solvent for prolonged release suspension for injection (proposed trade name BYDUREON™) in the European Union for the treatment of type 2 diabetes in combination with certain oral therapies. This application to the European regulatory authorities is for use of BYDUREON as a once-weekly 2 mg dose to improve glycemic control in adults who have not achieved adequate glycemic control on maximally tolerated doses of these oral therapies. If approved, BYDUREON would be the first once-weekly type 2 diabetes treatment.
The CHMP's positive opinion is now referred for final action by the European Commission, which has the authority to approve medicines for the European Union. The Commission usually makes a decision on CHMP recommendations within two to three months.
"The CHMP's positive opinion is a pivotal step toward marketing authorization for BYDUREON in Europe. If approved, BYDUREON will offer patients the benefits of a GLP-1 receptor agonist in a once-weekly injection," said Enrique Conterno, president, Lilly Diabetes. "We remain deeply committed to advancing the treatment of diabetes through innovative treatment options and solutions that meet the specific needs of millions of people living with diabetes."
The positive opinion was reached after CHMP review of the submission package, including data from studies in the DURATION clinical program in which exenatide resulted in improvements in glycemic control with just one dose per week. In the data submitted, BYDUREON showed statistically significant improvements in glycemic control based on reduction of A1C, a measure of average blood sugar over three months, between 1.5 and 1.9 percent after six months. Although BYDUREON was not studied as a weight-loss product, most patients taking BYDUREON lost weight. Further, the BYDUREON submission builds upon more than five years of market experience with BYETTA® (exenatide) injection, the twice-daily form of exenatide that is available in more than 70 countries worldwide. The most common side effect with BYDUREON in clinical trials was mild-to-moderate nausea, which affected approximately 20 percent of patients and decreased over time in most patients. Other common side effects were vomiting, diarrhea and constipation.
The companies are seeking approval of BYDUREON as a once-weekly 2 mg dose for the treatment of type 2 diabetes in combination with metformin, a sulfonylurea, a thiazolidinedione, metformin plus a sulfonylurea or metformin plus a thiazolidinedione.
In the U.S., the New Drug Application for BYDUREON (exenatide extended-release for injectable suspension) was submitted to the U.S. Food and Drug Administration (FDA) in 2009. The FDA issued a complete response letter and requested further data in late 2010. The companies plan to submit a response in the second half of 2011.
BYDUREON belongs to the class of glucagon-like peptide-1 (GLP-1) receptor agonists. With just one weekly dose, a continuous release of exenatide is delivered using Medisorb®, a biodegradable microsphere technology developed by Alkermes.
Diabetes affects an estimated 285 million adults worldwide and nearly 26 million people in the U.S. (i),(ii) Approximately 90-95 percent of those affected have type 2 diabetes. Diabetes costs approximately $174 billion per year in direct and indirect medical expenses.(iii)
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.(iv) In addition, 85 percent of type 2 diabetes patients are overweight and 55 percent are considered obese.(v) Data indicate that weight loss (even a modest amount) supports patients in their efforts to achieve and sustain glycemic control.(vi),(vii)
About BYETTA® (exenatide) injection
BYETTA was the first glucagon-like peptide-1 (GLP-1) receptor agonist to be approved by the FDA for the treatment of type 2 diabetes. BYETTA exhibits many of the same effects as the human incretin hormone 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 an injectable prescription medicine that may improve blood sugar (glucose) control in adults with type 2 diabetes mellitus, when used with a diet and exercise program. BYETTA is not insulin and should not be taken instead of insulin. BYETTA is not currently recommended to be taken with insulin. BYETTA is not for people with type 1 diabetes or people with diabetic ketoacidosis. BYETTA has not been studied in people who have pancreatitis.
BYETTA provides sustained A1C control and low incidence of hypoglycemia when used alone or in combination with metformin or a thiazolidinedione, with potential weight loss (BYETTA is not a weight-loss product). BYETTA was approved in the U.S. in April 2005 and in Europe in November 2006 and has been used by more than 1.8 million patients since its introduction. See important safety information below. Additional information about BYETTA is available at www.BYETTA.com.
Important Safety Information for BYETTA® (exenatide) injection
Based on postmarketing data BYETTA has been associated with acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. Patients should be observed for signs and symptoms of pancreatitis after initiation or dose escalation of BYETTA. The risk for getting low blood sugar is higher if BYETTA is taken with another medicine that can cause low blood sugar, such as a sulfonylurea. BYETTA should not be used in people who have severe kidney problems and should be used with caution in people who have had a kidney transplant. Patients should talk with their healthcare provider if they have severe problems with their stomach, such as delayed emptying of the stomach (gastroparesis) or problems with digesting food. Antibodies may develop with use of BYETTA. Patients who develop high titers to exenatide could have worsening or failure to achieve adequate glycemic control. Consider alternative therapy if this occurs. Severe allergic reactions can happen with BYETTA. There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with BYETTA or any other antidiabetic drug.
The most common side effects with BYETTA include nausea, vomiting, diarrhea, dizziness, headache, feeling jittery, and acid stomach. Nausea most commonly happens when first starting BYETTA, but may become less over time.
These are not all the side effects from use of BYETTA. A healthcare provider should be consulted about any side effect that is bothersome or does not go away.
