Details and patient eligibility
About
The purpose of this study is to compare the single-dose pharmacokinetics of ASP2215 in subjects with mild and moderate hepatic impairment to matched healthy subjects with normal hepatic function.
This study will also assess the safety and tolerability of single-dose ASP2215 in subjects with mild and moderate hepatic impairment and matched control subjects.
Full description
Subjects will be admitted to the site one day before each study drug administration (i.e. Day -1) and confined at the site till the collection of post-dose PK samples (Day 21). For subjects with hepatic impairment, subject will discharge on Day 21, and will visit the clinical unit on Day 24 (±1 day) and Day 28 (±1 day) for collection of post-dose PK samples. End of study Visit For Healthy subjects will take place 1 to 5 days following collection of last PK sample.
