This study is an open-label, randomized, fasting, single-dose, 2-group, 2-period, crossover design to evaluate pharmacokinetics that are not affected by blinding. According to the order of administering the investigational drug for each period, 17 people are assigned to each of the two groups and administered.~For healthy subjects, each 17 subjects are assigned to each of the two groups(total 34 subjects). If the subject administrate GC2129A in the first period, the subject will be administrated reference drugs in the second period after washout(over 7 days). Conversely, if the subject administrate reference drugs in the first period, the subject will be administrated with GC2129A in the second period.
The purpose of this study is to evaluate the safety and pharmacokinetics of oral administration of GC2129A in fed conditions to healthy adult volunteers.
