A Study to Assess the Relative Bioavailability of 3 Different Formulations Under Fasted and Fed Condition

This study will be a randomised, open-label, single-dose, 5-period, 5-treatment, crossover study in healthy male and female participants, performed at a single study centre. This study is intended to assess the relative bioavailability between the ER8 capsule formulation (the formulation that is currently used for verinurad development) given under fasted conditions and 2 new capsule formulation of verinurad (A-capsule and B-capsule) given under fed or fasted conditions. All three capsules target an 8-hour release profile (extended-release). The highest dose (12 mg) currently tested in participants will be tested in this study. The study is designed to provide information to optimize the verinurad part of a fixed dose combination capsule to be used in future development. The study will comprise: a screening period of maximum 28 days; five treatment periods during which participants will be resident from the morning of the day before dosing with verinurad (Day -1) until at least 72 hours after dosing; discharged on the morning of Day 4 of each Treatment Period; and a follow-up Visit within 7 to 14 days after the last administration of verinurad. There will be a minimum washout period of 5 days between each dose administration. A total of 25 healthy male and female participants will be randomised into this study. Each participant will receive five single-dose treatments of 12 mg verinurad with 240 mL water, following an overnight fast of at least 10 hours. Participants will follow an overnight fast of at least 10 hours before the dosing procedures: for the fed dosing, a high-fat, high-calorie standard breakfast will be served 30 minutes before the planned administration of verinurad to be consumed in full at least 5 minutes before dosing; for the fasted dosing, no breakfast will be served. A meal can be given 4 hours after administration of verinurad for both dosing states. The duration of the study is expected to be approximately 9 weeks for each individual participant (including the 28-day screening period).
