A Randomized, Open-Label, 4-Way Crossover Replicate Design Study to Evaluate the Relative Bioavailability and Intra-Subject Variability of Two Lots of E5501 40 mg Tablets Administered Twice as Single Oral Doses to Healthy Subjects
The purpose of this study is to evaluate the relative bioavailability (BA) of two lots of E5501 40 mg tablets administered twice as single oral doses to healthy subjects.
