Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This trial contains Part A, Part B and Part C, all enrolling healthy Chinese subjects.

Part A is a single ascending dose study of VB19055 tablets in healthy Chinese adult participants. Part B is a randomized, single-dose, two-period, crossover study designed to evaluate the effect of food on the pharmacokinetic characteristics of VB19055 tablets in healthy Chinese adult participants.Part C is a multiple ascending dose study of VB19055 tablets in healthy Chinese adult participants.

Part A will be conducted first, and Parts B and C will be initiated when appropriate based on the preliminary data obtained during the study.
