Summary
Brief summary
This study will be conducted in two stages and will test the safety/tolerability,
pharmacokinetics (how the body handles study drug) and pharmacodynamics (effects on the
immune system and the virus) of the study drug ABBV-181 in Human immunodeficiency virus
(HIV)-1 infected participants undergoing Antiretroviral therapy (ART) interruption.
