The study will have 2 independent parts:
Part 1 of the study is intended to collect samples for Metabolites in Safety Testing (MIST) analysis after administration of multiple doses of zibotentan.
Part 2 of the study is designed to evaluate the relative bioavailability of zibotentan and dapagliflozin after dosing with two different fixed-dose combination (FDC) formulations and dosing with separate formulations of zibotentan and dapagliflozin.
Part 1 will be an open-label, non-randomised, single treatment period. A single treatment period during which participants will be resident at the study centre from 2 days before dosing (Day -2) until the morning of Day 6.
Part 2 will be an open-label, randomised, 3-period, 3-treatment, cross-over single dose study. Participants will be randomised to one of 3 treatment sequences and will receive 3 single-dose study interventions. Participants will be resident at the study centre from 2 days before dosing (Day -2) until Day 3 of the last treatment sequence.
Participants who were enrolled in Part 1 may not be enrolled in Part 2.
