New Diabetes Drug Works Well in Trial

A contest may develop between liraglutide and a once-a-week formulation of exenatide, Buse said. The longer-lasting exenatide version is expected to reach the U.S. market in about a year. It requires a standard hypodermic needle for injection, while liraglutide can be given through a small, ultrafine needle.

Several other GLP-1 drugs are in trials now and might be approved before long, Buse said. "It will be a great opportunity for patients to have so many choices," he added.
