Brief summary
This is a randomized, open label, single dose, two-period, crossover trial phase I study. The purpose of this study is to evaluate the food effect on the pharmacokinetics（PK） of SIM0270 after oral administration under fasted, standard meal, or high-fat diet conditions.
Detailed description
Part A High Fat Meal Test: Sixteen healthy adult subjects are planned to be enrolled and randomly assigned to different dosing sequence groups (Group 1 and Group 2) in a 1:1 ratio for a two-period crossover trial. The subjects administered a single dose of SIM0270 under fasted, or high-fat diet conditions. Part B Standard Meal Test (optional part): Sixteen healthy adult subjects are planned to be enrolled and randomly assigned to different dosing sequence groups (Group 3 and Group 4) in a 1:1 ratio for a two-period crossover trial. The subjects administered a single dose of SIM0270 under fasted, or standard meal conditions.
