Single/ Multiple-Dose Study of E6007 in Healthy Japanese Male Subjects
Study Details
Study Description
Brief Summary
This is a single-center, placebo-controlled, randomized, ascending dose, double-blind study. This study will be evaluating ascending doses of 50, 100, 200, and 400 mg of E6007. This study consists of 5 steps, 1 to 5. In steps 1 to 4 (at ascending doses of 50, 100, 200, and 400 mg), subjects will be randomly assigned in a 6:2 ratio (E6007: placebo) to receive single dose of the study drug under fasted condition. Following 3 days of washout period, subject will receive the study drug once daily for 7 days starting on the fifth day from the single dose administration.
For step 3 (200 mg), subjects will subsequently have at least 17 days of washout period before being escalated to step 5 (200 mg) to receive single dose of E6007 under fed condition, to evaluate food effect of the study drug.

- Plasma E6007 concentration over time period - tmax (Time to achieve maximum concentration (Cmax)) [Up to 15 days]
- Plasma E6007 concentration over time period - AUC (0-t) (Area Under the Curve (AUC) from Time Zero to Last Quantifiable Concentration) [Up to 15 days]
- Plasma E6007 concentration over time period - AUC (0-inf) (AUC extrapolated to infinity) [Up to 15 days]
- Plasma E6007 concentration over time period - t1/2 (Terminal phase half-life) [Up to 15 days]
- Plasma E6007 concentration over time period - CL/F (Apparent clearance) [Up to 15 days]

Secondary Outcome Measures
- Dose proportionality under fasted conditions with Cmax, AUC (0-t), AUC(0-inf), Cssmax and AUC(0-t) [Up to 15 days]
- Geometric mean proportion (fed:fasted) of Cmax, AUC(0-t) and AUC(0-inf) for 200mg E6007 dose [Up to 5 days]
- Evaluate relationship between E6007 plasma concentrations and electrocardiogram (ECG) parameter (QTcF) [Up to 15 days]
