This multiple-center, nonrandomized, open label, parallel group, single dose study will be conducted in male and female subjects with normal hepatic function or moderate (Child-Pugh Class B) hepatic impairment to evaluate the effect of hepatic impairment on the pharmacokinetics (PK) of KBP-5074.

Key Inclusion Criteria:

1. Males or females, of any race, between 18 and 80 years of age, inclusive, at screening.
2. Body mass index between 18.0 and 40.0 kg/m2, inclusive, at screening.
3. Subjects with normal hepatic function must be in good health.
4. Subjects must meet the criteria for moderate hepatic impairment based on Child Pugh B.

Key Exclusion Criteria:

1. Significant history or clinical manifestation of any medical history, as determined by the investigator not appropriate to participate in this study.
2. Positive serology test results for hepatitis B surface antigen and/or human immunodeficiency virus 1/2.
3. Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 30 days or 5 half-lives prior to dosing, whichever is longer.
4. Use of mineralocorticoids or MRAs (eg, spironolactone or eplenerone) within 90 days prior to study drug administration, unless deemed acceptable by the medical monitor and sponsor.
5. Subject has used prescription drugs within 30 days of study drug administration, with the exception of established therapy for hepatic disease and the treatment of associated disorders that have been stable for at least 30 days before study drug administration, as approved by the investigator and in consultation with the medical monitor.
