This is a phase 1 trial to evaluate the safety, tolerability, and pharmacokinetics of 4 different oral formulations of LEO 32731 in healthy subjects. The trial will be conducted in 3 parts at a single site. Each eligible subject will be enrolled into 1 group only and will participate in 3 treatment periods.
Part 1 will evaluate the pharmacokinetics of single doses of 4 test formulations of LEO 32731 compared with a reference formulation. Part 2 will evaluate the effect of food on the pharmacokinetics of selected test formulations of LEO 32731. Part 3 will evaluate the tolerability and safety of selected test formulations of LEO 32731 after multiple dosing.
Based on data from Part 1, up to 3 formulations will be taken forward to Part 2. If none of the formulations are considered appropriate to take forward to Part 2, the trial will stop after Part 1. Similarly, based on data from Part 2, up to 2 formulations will be taken forward to Part 3. If none of the formulations are considered appropriate to take forward to Part 3, the trial will stop after Part 2.
