A Study to Investigate the Relative Bioavailability and Food Effect of an Oral Capsid Inhibitor Tablet Formulation Compared With Other Oral Tablet Formulations in Male and Female Healthy Participants

Study Overview
=================
Brief Summary
-----------------
This is a 2 part study of an investigational capsid inhibitor, VH4004280, in healthy adult participants. The purpose is to evaluate the effect of tablet formulation as well as food on bioavailability. Part 1 of the study will compare the relative bioavailability of VH4004280 Formulation A tablets to up to 4 alternative tablet formulations under fed (high fat) conditions. Part 2 of the study will assess the effect of fasted conditions on the bioavailability of VH4004280 Formulation A and alternative, optional formulations, relative to their respective bioavailability under fed conditions in Part 1.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with AEs (Adverse Events), by severity | An AE is any untoward medical occurrence in a participant or clinical investigation participant and can be any sign, symptom, or disease temporally associated with the use of a medicinal product. The severity scale is assessed as following: Grade 1 = mild symptoms causing no or minimal interference with usual social and functional activities with intervention not indicated. Grade 2 = moderate symptoms causing greater than minimal interference with usual social and functional activities with intervention indicated. Grade 3 = severe symptoms causing inability to perform usual social and functional activities with intervention or hospitalization indicated. Grade 4 = potentially life-threatening symptoms causing inability to perform self-care functions with intervention indicated to prevent permanent impairment, persistent disability, or death. | From Day 1 to Day 49 | 
| Number of participants with maximum toxicity grade increase from baseline for liver laboratory parameters | The assessed laboratory assessments include Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), alkaline phosphatase (ALP), direct bilirubin and total bilirubin, in both fed and fasted conditions. | From Day 1 to Day 49 | 
| Change from baseline in liver panel parameters: Total bilirubin and direct bilirubin (micromoles per liter) |  | From Day 1 to Day 49 | 
| Change from baseline in liver panel parameters: ALT, ALP and AST (International units per liter) |  | From Day 1 to Day 49 |
