first-time-in-human (ftih) study to evaluate the safety, tolerability and pharmacokinetics (pk) of vh4011499 in healthy participants

Conditions: HIV Infections

Summary: this ftih study aims to evaluate the safety, tolerability and pk of the novel investigational human immunodeficiency virus (hiv)-1 capsid inhibitor vh4011499 in healthy adults. the study will be conducted in 3 parts: part 1 will investigate single ascending doses (sad) and part 2 will investigate multiple ascending doses (mad). part 3 will investigate single dose of a new formulation of vh4011499. the transition from sad to mad will be based on the assessment of the safety and dose escalation committee.
