Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1, single dose (200 mg), open-label study comparing the pharmacokinetics and safety of Pretomanid in subjects with mild, moderate, and severe hepatic impairment to matched, non-hepatically impaired subjects. There will be approximately 36 total subjects, adult males and females, 18 to 70 years of age, inclusive. The study will be conducted at 2 sites, study duration is approximately 24 months, and subject participation duration is approximately 5 weeks (including screening). Primary objective: To evaluate the pharmacokinetics of a single oral dose of Pretomanid in subjects with mild, moderate, and severe hepatic impairment (as assessed by Child-Pugh score), relative to matched non-hepatically impaired subjects. Secondary objective: To evaluate the safety of a single oral dose of Pretomanid in subjects with mild, moderate, and severe hepatic impairment (as assessed by Child-Pugh score), relative to matched non-hepatically impaired subjects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1, single dose (200 mg), open-label study comparing the pharmacokinetics and safety of Pretomanid in subjects with mild, moderate, and severe hepatic impairment to matched, non-hepatically impaired subjects. This study will enroll approximately 6 subjects with mild hepatic impairment (Child-Pugh A), approximately 6 subjects with moderate hepatic impairment (Child-Pugh B), approximately 6 subjects with severe hepatic impairment (Child-Pugh C), and approximately 18 matched non-hepatically impaired subjects. Non-hepatically impaired subjects in the control group will be matched to subjects with hepatic impairment based on age (+/- 10 years) and body weight (+/- 20 percent) as measured at screening (Visit 00A). There will be approximately 36 total subjects, adult males and females, 18 to 70 years of age, inclusive. The study will be conducted at 2 sites, study duration is approximately 24 months, and subject participation duration is approximately 5 weeks (including screening). Primary objective: To evaluate the pharmacokinetics of a single oral dose of Pretomanid in subjects with mild, moderate, and severe hepatic impairment (as assessed by Child-Pugh score), relative to matched non-hepatically impaired subjects. Secondary objective: To evaluate the safety of a single oral dose of Pretomanid in subjects with mild, moderate, and severe hepatic impairment (as assessed by Child-Pugh score), relative to matched non-hepatically impaired subjects.
