Evaluation and Validation of Endogenous Markers for the Assessment of CYP3A Activity in Korean Healthy Subjects Using Metabolomics (CYP3A_basal)
April 15, 2016 updated by: Joo-Youn Cho, Seoul National University Hospital
The study objective is to evaluate and validate of endogenous markers for the assessment of CYP3A activity in Korean healthy subjects using metabolomics.
In part 1, total 75 healthy subjects (males and females) will be enrolled. In part 2, total 25 healthy female subject aged 20-45 years will be enrolled. In both part A and B, subjects will be administered midazolam I.V. 1 mg.
