- Brief Summary
This study is to assess the bioequivalence of a test formulation of vadadustat (A) compared to a reference formulation of vadadustat (B)
- Detailed Description
This is a randomized, open-label, single-dose, two-period crossover study in healthy adults to assess the bioequivalence of a test formulation of vadadustat compared to the reference formulation of vadadustat. Blood samples for vadadustat PK will be collected at pre-dose (0 hour) and at 0.5, 1, 1.5, 2, 3, 4, 6, 9, 12, 18, 24, 32, 40, and 48 hours post-dose.
