Filter by:The study investigates how safe ASP3652 is and how well it is tolerated when taken as multiple doses. The study also assesses how quickly and to what extent it is absorbed and eliminated from the body. In addition, the effects of age and gender are investigated. The study consists of two parts. In Part 1 four dose levels are administered to four separate groups initially. Two additional dosages are then investigated. Subjects receive either a once-daily dose (QD) or twice-daily dose (BID) of ASP3652 or placebo. Part 2 is performed in one group of elderly healthy male or female (post-menopausal) subjects. Subjects receive either a twice daily dose (BID) of ASP3652 or placebo. For both parts of the study, the subjects stay in the clinic for one period of 18 days.
The purpose of this study is to evaluate the plasma and cerebrospinal fluid (CSF) pharmacokinetics (PK) of multiple doses of ASP3652 in healthy young Caucasian male subjects. Also to evaluate the plasma and CSF pharmacodynamics (PD) of multiple doses of ASP3652 in healthy young Caucasian male subjects and to assess the safety and tolerability of multiple doses of ASP3652 in healthy young Caucasian male subjects.
