NameTimeMethod
To evaluate the pharmacokinetics (PK) [area under the time-concentration curve] of a single-dose of tozadenant in subjects with hepatic impairment to healthy subjects.up to 12 days

To evaluate the pharmacokinetics (PK) \[area under the time-concentration curve\] of a single-dose of tozadenant in subjects with hepatic impairment compared to the PK of a single-dose of tozadenant in healthy subjects.

Secondary Outcome Measures
NameTimeMethod
Subjects with hepatic impairment will be evaluated for safety assessments (adverse events and treatment-related adverse events) by physical examinations.up to 12 days

To evaluate the safety and tolerability of a single-dose of tozadenant in subjects with hepatic impairment by physical examinations, vital sign measurements and Columbia-Suicide Severity Rating Scale (C-SSRS) questionnaire.
