This study is a randomized, open-label, multiple dosing, crossover study to evaluate the drug-drugs interaction between Lobeglitazone and Empagliflozin in healthy male volunteers

To healthy male subjects of 30, following treatments are administered dosing in each 3 period(Lobeglitazone or Empagliflozin or Lobe.+Empa.) and wash-out period is a minimum of 7 days.

Test Drug 1: Lobeglitazone 0.5mg 1T

Test Drug 2: Empagliflozin 25mg 1T

Pharmacokinetic blood samples are collected up to 24hrs.

Safety, pharmacokinetic and the drug-drugs interaction are assessed.

Inclusion Criteria:

1. A healthy person whose age is in between 19 to 45 during the screening tests
2. Whose weight is more than 55 kg, BMI is over 18.5 and under 29.9 during the screening test. (BMI (kg/m2) = weight (kg) / {height (m)}2)
3. A male with no congenital or chronic disease in three years, no history of symptoms in internal treatment, or no knowledge in the area
4. Due to the special characteristics of drugs, the participators must be qualified to do the clinical screening tests
5. The participants must have an ability and willingness to participate throughout the entire trials
