Many people with type 2 diabetes cannot maintain target blood glucose levels when taking a single oral drug. The purpose of this study is to assess the long term safety and effectiveness of vildagliptin, an unapproved drug, compared to that of glimepiride in lowering overall blood glucose levels when added to metformin in people with type 2 diabetes not at target blood glucose levels on metformin alone.
