Developmental phase



Assessment

Primary outcomes

1. The total blood concentration and free form blood concentration(including optical isomers) of Perampanel and its metabolites.
2. Free form fraction of Perampanel and its metabolites.
3. Blood kinetics Parameter fluctuation factors(clinical laboratory values, glycoalbumin, diseases, concomitant medications, inflammatory markers, liver, and kidney function marker).

Study1: Relationship between blood levels and side effects (psychiatric symptoms, somnolence, weight gain).
Study2: Relationship between blood concentration and liver function marker(4-beta hydroxylated cholesterol in the blood, 25 hydroxylated vitamin D in blood, 25 hydroxylated vitamin D3 in blood, miRNA-24b), Genetic polymorphism of drug-metabolizing enzyme(CYP3A4, CYP3A5), etc.).
