Brief summary:
The aim of this study is to investigate the efficacy and safety of two doses (high and low) of empagliflozin as add-on therapy to metformin in patients with type 2 diabetes mellitus (T2DM) and insufficient glycaemic control. Both doses may be given once daily or split to a twice daily dosage. This results in 4 different dosage regimens of empagliflozin (high dose once daily or split vs. low dose once daily or split). This is done to evaluate whether a twice daily dose regimen of empagliflozin results in a loss of efficacy relative to once daily dosing when given on top of metformin background therapy.
