Pharmacokinetics of KBP-5074 in Patients With Moderate Hepatic Impairment

December 8, 2025 updated by: KBP Biosciences

A Phase 1, Open Label, Nonrandomized, Single-dose Study to Investigate the Safety, Tolerability, and Pharmacokinetics of KBP-5074 in Subjects With Moderate Hepatic Impairment Compared to Subjects With Normal Hepatic Function

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 76 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

  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.

  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.
