Inclusion and exclusion criteria

[Healthy Control Group]

• Subjects who have no chronic disease or any congenital disease within the last 5 years and no pathological symptoms or findings as a result of an internal examination
• Subjects who provide voluntary written informed consent to study participation after being informed of detailed explanation and fully understanding study objectives, procedures and characteristics of the investigational product(IP).

Exclusion Criteria:

• Subjects with any clinically significant disease related to ongoing cardiovascular problem, respiratory system, kidney, endocrine system, hematologic, central nervous system, mental health disorder, or malignant tumor.
• Subjects with history or current evidence of gastrointestinal or hepatobiliary disease which may affect PK evaluation of the IP.
