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