NCT06678542

Brief Summary

The primary objective is to evaluate the relative bioavailability and pharmacokinetic profile of a single oral dose of the test formulation, GP681 Powder for Oral Suspension (20 mg/sachet), compared to the reference formulation, GP681 tablet (20 mg/tablet), in healthy Chinese male subjects. The secondary objectives are to assess the safety of a single oral dose of the GP681 Powder for Oral Suspension (20 mg/sachet) and GP681 tablet (20 mg/tablet) in healthy Chinese male subjects, as well as the palatability (taste acceptability) of the GP681 Powder for Oral Suspension.
