This study is to compare the safety/tolerability and pharmacokinetics/pharmacodynamics of the fixed-dose combinations of gemigliptin/metformin HCl sustained release 50/1000 mg (25/500 mg x 2 tablets) in comparison to each component gemigliptin 50 mg and metformin HCl extended release 1000 mg (500mg x 2 tablets) under fasting and fed conditions in healthy male volunteers.

This study will be conducted in separtes 2 Parts.
