A Phase I, Randomized, Open-label, Single-dose, Four-period, Four-treatment, Cross-over Study to Assess the Pharmacokinetics of Zibotentan in Healthy Non-Asian and Japanese Participants

Description

This study aim to assess the Pharmacokinetics of Zibotentan in Healthy Non-Asian and Japanese Participants.This study will be Phase I, randomized, open-label, single-dose, 4-period, 4-treatment, cross-over study, performed at a single study center. The study will comprise: Screening Period of maximum 28 days; Four Treatment Periods, separated by 3 washout periods; Final Follow-up Visit within 5 to 7 days after the last study intervention administration. The washout periods will last at least 3 days, resulting in a total dosing-free time of at least 6 full days between each of the 4 treatments. Participant will receive the first dose is on Day 1, then the next dose will be on Day 8 at the earliest. Each participant will receive 4 different single doses (Dose 1, 2, 3 and 4) of zibotentan, at all 4 studied dose levels in one of the following treatment sequences: ABCD, BDAC, CADB, DCBA. Each participant will be involved in the study for approximately 9 weeks, depending upon the duration
