CKD-506 and placebo will be given in the form of oral capsules. Group 4 (only the second period): When the volunteer is participating in Group 4, he/she are also participating in the FE study part and will therefore participate in 2 study periods.

When the volunteer receives CKD-506 in the first period, he/she will also receive CKD-506 in the second period.
