Clinical Trial Summary

This is a single-centre, 2-part, randomised, single-dose parallel group study in healthy male subjects and female subjects of non-childbearing potential.

Description:

Parts 1 and 2 will be randomised with 8 subjects receiving each regimen:

Part 1:

• Regimen A: Reference: 800 mg OZ439 + α-Tocopherol polyethylene glycol 1000 succinate (TPGS) granules (oral suspension 240 mL volume and 100 mL rinse volume) and 960 mg (3 × 320 mg) PQP tablets

• Regimen B: Prototype 1: 800 mg OZ439 granules (oral suspension 60 mL volume and 50 mL rinse volume) and 960 mg (3 × 320 mg) PQP tablets

• Regimen C: Prototype 3: 800 mg OZ439 granules (oral suspension 60 mL volume and 50 mL rinse volume) and 960 mg (3 × 320 mg) PQP tablets

There will be an interim decision after Part 1 to determine the formulation prototypes and the oral suspension volume to be administered in Part 2.

Part 2

• Regimen D: Reference: 800 mg OZ439 + TPGS granules (oral suspension 240 mL volume and 100 mL rinse volume) and 960 mg (3 × 320 mg) PQP tablets

• Regimen E: Prototype 1 or 3: 800 mg OZ439 granules (oral suspension and rinse volume to be determined) and 960 mg (3 × 320 mg) PQP tablets

• Regimen F: Prototype 1 or 3: 800 mg OZ439 granules (oral suspension and rinse volume to be determined) and 960 mg (3 × 320 mg) PQP tablets
