Study to Collect Samples for MIST Analysis of Zibotentan and Bioavailability of Zibotentan and Dapagliflozin in Heatlhy Participants

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.

Key information

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Primary outcomes

  1. Part 1: Metabolites in Safety Testing sampling

    Time frame: Day 1 through Day 6 (pre-dose, 30 min; 1, 2, 4, 6, 8, 12 and 24 hours post dose)

    Plasma sample will be collected to understand the PK profiling of zibotentan metabolites and to meet the regulatory requirements.

  2. Part 2: Area under plasma concentration time curve from zero to infinity (AUCinf)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

  3. Part 2: Area under the plasma concentration curve from zero to the last quantifiable concentration (AUClast)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

  4. Part 2: Maximum observed plasma drug concentration (Cmax)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

  5. Part 2: Observed concentration at 24 hours post-dose (C24)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

Secondary outcomes

  1. Part 2: Time to reach peak or maximum observed concentration (tmax)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

  2. Part 2: Terminal rate constant (λz)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

  3. Part 2: Half life associated with λz (t½λz)

    Time frame: Day 1 through Day 3 of each treatment period

    Relative bioavailability of zibotentan and dapagliflozin after dosing with two different FDC formulations and dosing with separate formulations of zibotentan and dapagliflozin will be evaluated.

  4. Part 2: Apparent total body clearance of drug from plasma after extravascular administration (CL/F)

    Time frame: Day 1 through Day 3 of each treatment period
