Participants will be randomized 1:1 to receive dapagliflozin 10 mg qd or glimepiride 1~2 mgqd in an open-label manner for 12 months as add-on to metformin 1000 mg.

Parallel group study design was chosen. In order maintain the practicality of the phase IV study, open label design of study drug delivery was chosen. The reading of the DXA scans will be conducted by one expert in blinded manner.
