A Study in Healthy Subjects to Assess Drug Availability of 4 Different Formulations of Verinurad and Allopurinol

AstraZeneca25 enrolled

Overview

This study is a single centre, randomised, open-label, single-dose, 5-period, 5-treatment, crossover study in healthy male and female subjects. This study is intended to assess the relative bioavailability between the fixed dose combination (FDC, i.e. verinurad/allopurinol FDC capsule 12/300 mg) and free combination formulations of verinurad (i.e. verinurad prolonged release Hydroxypropyl methylcellulose \[HPMC\] capsule 12 mg) and allopurinol (i.e. allopurinol table 300 mg) in fasted and fed conditions. The study will also assess the relative bioavailability between a formulation only containing verinurad (i.e. verinurad prolonged release gelatin capsule 12 mg) and the FDC capsule.

The study comprises of: * A Screening Period of maximum 28 days; * Five treatment periods during which subjects will be resident from the morning of Day -2 until at least 72 hours after dosing in Treatment Period 5; discharged on the morning of Day 4 of Treatment Period 5; and * A Follow-up Visit 7 to 14 days after the last dosing. Each subject will receive 5 single dose treatments of verinurad and allopurinol or verinurad alone and subject will be involved in the study for 52 to 59 days.
