Summary

The purpose of this study is to learn whether having the AMP Study antibody (called VRC01) in a person's body might help their immune system control HIV better, even without HIV medication called antiretroviral therapy or ART, if they get HIV. This study will evaluate the viral and immune system responses in an Analytical Treatment Interruption (ATI), in participants who received VRC01 or placebo and got HIV while enrolled in HVTN 704/HPTN 085 (NCT02716675).

Participants in this study will stop taking their HIV medication. They will stay off HIV medication unless and until the HIV levels in their blood show that their immune system is unable to control the HIV or they meet other ART re-start criteria as noted in section "Detailed Description". While they are not taking HIV medication, their HIV levels will be tested frequently, and their health will be monitored closely. This is called an analytical treatment interruption, or an ATI. An ATI is an experimental procedure that is only used in carefully monitored research.
