Brief Summary: Background

Antiretroviral therapy ART can suppress HIV to undetectable levels in people but the virus rebounds quickly if the drug treatment is stopped this is because HIV can remain dormant in a pool of blood cells called the persistent viral reservoir PVR Yet lifelong ART is expensive and can lead to serious side effects over the long term Some drugs may be more effective at reducing the PVR

Objective

To see if 2 study drugs 3BNC117-LS and 10-1074-LS are safe and if they can lower the number of HIV-infected blood cells in people with HIV who are on ART

Eligibility

People aged 18 to 70 years with HIV who are on ART

Design

Participants will be screened They will have a physical exam and blood and urine tests They will undergo leukapheresis Leukapheresis is a procedure where blood is drawn from a needle in one arm The blood will pass through a machine that separates out the white blood cells The remaining blood will be given back through a second needle in the other arm

The study drugs or placebo normal saline will be administered 3 times at 20-week intervals The drugs will be given through a tube attached to a needle inserted into a vein in the arm This will take 1 hour Some participants will receive only a saline solution They will not know if they are getting the drugs or the placebo

Participants will undergo leukapheresis up to 4 more times during the study

Participants will have follow-up visits every 10 weeks until the study ends
Detailed Description: Study Description

This is randomized placebo-controlled study of the safety and virologic activity of the 3BNC117-LS plus 10-1074-LS broadly neutralizing antibody bNAb combination during standard antiretroviral therapy ART

Participants will be enrolled sequentially and randomized to receive 3BNC117-LS plus 10-1074-LS or placebo sterile saline at a 11 ratio Participants will receive two intravenous infusions of 3BNC117-LS dosed at 30 mgkg and 10-1074-LS dosed at 10 mgkg or placebo at weeks 0 and 20 Participants will remain on ART during the study

Objectives

Primary Objectives
