To Compare the Safety and PK/ PD Characteristics of ADC189 Between Hepatic Impairment and Normal Hepatic Function Subjects

An Phase I, Open-label, Multi-center, Parallel, Single Oral Dose Study to Evaluate the Pharmacokinetics, Pharmacodynamics, Safety, and Tolerability of ADC189 in Subjects With Hepatic Impairment (Child-Pugh A and B) Compared With Subjects With Normal Hepatic Function

This study aims to evaluate the pharmacokinetics, pharmacodynamics, safety, and tolerability of ADC189 in subjects with hepatic impairment compared with subjects with normal hepatic function.

The evaluation of ADC189/ADC189-I07 in mild hepatic insufficiency (Child-Pugh A), moderate hepatic insufficiency (Child-Pugh B) the pharmacokinetic characteristics in subjects, compared with normal liver function subjects, which matched by sex, age, and BMI, in order to provide a scientific basis for a reasonable dosage in patients with liver dysfunction.
