A Phase 1 Open-label Study to Evaluate the Effect of Mild and Moderate Hepatic Impairment on the Pharmacokinetics, Safety and Tolerability of ASP0367 Compared to Participants With Normal Hepatic Function

0367-CL-1102

The purpose of this study is to evaluate the effect of ASP0367 in participants with mild and moderate hepatic impairment compared to healthy participants with normal hepatic function. The study will also evaluate the safety and tolerability of ASP0367 in participants with mild and moderate hepatic impairment compared to healthy participants with normal hepatic function.

In such a case, the assessment may be repeated once. Additional Criteria for Participants with Hepatic Impairment: * Participant has any history or evidence of any clinically significant cardiovascular, gastrointestinal, endocrinologic, hematologic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal and/or other major disease or malignancy not related to current disease state. * Participant has cardiac troponin I (cTnI) \> upper limit of normal (ULN) (or cardiac troponin T \[cTnT\]) \> ULN if cTnI is not available). In such a case, the assessment may be repeated once. * Participant has a mean pulse \< 45 or \> 100 bpm; mean systolic blood pressure \> 160 mmHg; mean diastolic blood pressure \> 100 mmHg (measurements taken in triplicate after participant has been resting in the supine position for at least 5 minutes; pulse will be measured automatically) on day -1.
