This is a Phase 1, two-part, open-label study to evaluate the interaction of cyclosporine, probenecid, and rifampin as perpetrators with vadadustat (victim) in healthy male and female subjects. Part 1 consists of 2 arms (cyclosporine and probenecid) and Part 2 consists of 1 arm (rifampin). Twenty (20) unique subjects will be enrolled into each study arm. The PK and safety/tolerability data from Part 1 Arm 1 (cyclosporine) will determine if Part 2 (rifampin) will proceed. Subjects will be on study for up to 72 days, including a 28-day screening period, 6-10 day clinic period, and a 30-day follow-up period post last dose. Blood and/or urine samples for PK analysis will be collected at pre-defined timepoints throughout the study.
