Phase I Pharmacokinetic Study of HUYPS-1 in Healthy Volunteers

Fasting Period: At least 10 hours prior to dosing until 4 hours post-dose of each study period. Period: 24 hours post dose in each period. Each subject will complete two study periods. Washout Period: At least one week after dosing of the previous period. Confinement: From at least 10 hours prior to dosing until at least 12 hours post-dose, for a total of at least 22 hours for each study period.

This study is a single center and open-label design to evaluate tolerability, safety and pharmacokinetic properties of HUYPS-1 after single oral administration in healthy subjects under fasting conditions. A total of 14 eligible subjects are expected to be enrolled to ensure 12 evaluable subjects. The study will be completed when there are at least 12 evaluable subjects. The evaluable subjects are those who have completed both periods. Eligible subjects will be randomly assigned to either of the two treatment sequences. The study design in a 2-sequence, 2-period crossover design. There is at least 7-day washout time between periods. The formulation of HUYPS-1 for oral administration contains 100 mg mannitol and 100 mg sucralose per tablet will be given by one or nine tablets per person of each period. Mannitol and sucralose are both commonly used excipients approved by WHO. These excipients are included in the FDA Inactive Ingredients Guide, GRAS (generally recognized as safe) and commonly used pharmaceutical excipients, therefore the oral doses of these excipients can be regarded as extremely safe in this study.
