Placebo Comparator: Double-Blind Placebo Multiple Dose
Matching placebo capsules will be administered orally as a single daily dose on days 1 through 14 with water. On days 1, 7, and 14, matching placebo capsules will be administered with food. On days 2-6 and 8-13, matching placebo will be administered under fed conditions.
Drug: Matching Placebo
Oral

Experimental: Open-Label ASP4345
ASP4345 will be administered orally as a single daily dose on days 1 through 14 with water. On days 1, 7, and 14, ASP4345 will be administered with food.
