A Phase 1, Open-Label, Single-Dose Study to Evaluate the Pharmacokinetics and Safety of Pretomanid in Participants With Renal Impairment Compared to Participants With Normal Renal Function

Description

This is a Phase 1, open-label, single-dose, sequential group study to compare the safety and pharmacokinetics (PK) of pretomanid in the following groups of participants: 1) participants with severe renal impairment including those with end stage renal disease (ESRD) not on dialysis, and participants with mild or moderate renal impairment, designated as Groups 2, 3, and 4, respectively; and 2) participants with normal renal function matched to the above renal impairment groups, designated as Groups 1A, 1B, and 1C, respectively. The study will be conducted following a reduced PK study design in Part A. Part A will enroll participants from Group 1A (i.e., 6 healthy matched controls) and Group 2 (i.e., 6 participants with severe renal impairment and ESRD, not on dialysis). A decision to proceed to Part B will be made after the PK of pretomanid, and safety in participants enrolled in Part A have been reviewed. If Part A demonstrates at least a 50% increase in pretomanid area under the plas
