Trial overview

Official title: A single centre, single dose, open-label, randomised, 2-way crossover study in healthy Japanese male subjects to evaluate the bioequivalence of daprodustat tablets (2 mg tablet vs. 4 mg tablet) (Part 1) and the food effect on the pharmacokinetics of daprodustat (Part 2)
Trial description: This is two-way crossover study to compare pharmacokinetic (PK) of daprodustat 2 milligram (mg) versus 4 mg tablets and food effect on the PK of daprodustat following single oral doses in healthy Japanese male subjects. This study will be conducted in two parts. Part 1 is the bioequivalence part in which subjects will receive single dose of 2 tablets of 2 mg daprodustat and single dose of 1 tablet of 4 mg daprodustat in crossover manner. Part 2 is Food effect part. In this part, subjects will receive single dose of 4 mg daprodustat tablet in fasting and fed state in a crossover manner. There will 5-day wash-out period between each intervention period. There will be approximately 52 subjects in Part 1 and 12 subjects in Part 2. The study will last for 6 weeks.
