A Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of ESN364 in Healthy Japanese Male and Pre- and Post-menopausal Female Subjects

The purpose of this study is to evaluate the safety and tolerability of single and multiple oral doses of ESN364 in healthy Japanese male and pre- and post-menopausal female subjects. This study will also evaluate the pharmacokinetics (PK) of ESN364 and its metabolite, and the pharmacodynamics (PD) of ESN364 after single and multiple oral doses administration in healthy Japanese male and pre- and post-menopausal female subjects.
