First-Time-in-Human (FTIH) Study to Evaluate the Safety, Tolerability and Pharmacokinetics (PK) of VH4004280 in Healthy Participants

This FTIH study aims to evaluate the safety, tolerability and PK of the novel investigational Human immunodeficiency virus (HIV)-1 capsid inhibitor VH4004280 in healthy adults. The study will be conducted in 3 parts: Part 1 will investigate single ascending doses (SAD), Part 2 will investigate multiple ascending doses and drug-drug interaction (MAD/MAD DDI) Part 3 will investigate single dose relative bioavailability (RBA) of a new formulation of VH4004280.
