Conditions

Chronic Hepatitis B

Brief summary

The purpose of this study is to evaluate the drug-drug-interaction (DDI), pharmacokinetics (PK) and tolerability of GLS4/RTV combined with TAF in healthy subjects.

Detailed description

This is a 2-part study with each part is an open-label study in healthy adult subjects. Total 28 subjects will be enrolled into the study and divided into 2 part (Part A and Part B), 14 subjects in each part. With each part, the subject will be receive study drug per the defined treatment periods.
