Effect of Liraglutide on Blood Glucose Control in Subjects With Type 2 Diabetes
LEAD-1
Liraglutide Effect and Action in Diabetes (LEAD-1): Effect on Glycaemic Control After Once Daily Administration of Liraglutide in Combination With Glimepiride Versus Glimepiride Monotherapy Versus Glimepiride and Rosiglitazone Combination Therapy in Subjects With Type 2 Diabetes.

Brief Summary
This trial is conducted globally (the United States of America excepted). This trial is designed to show the effect of treatment with liraglutide when added to existing glimepiride therapy and to compare this to both glimepiride monotherapy and to rosiglitazone as add-on therapy to glimepiride.
