A Study to Evaluate the Safety and Effects of Repeated Doses of 3BNC117-LS and 10-1074-LS on Persistent Viral Reservoirs in People Living With HIV and on Suppressive Antiretroviral Therapy
A Randomized Placebo-controlled Study to Evaluate the Safety and Effects of Repeated Doses of 3BNC117-LS and 10-1074-LS on Persistent Viral Reservoirs in People Living With HIV and on Suppressive Antiretroviral Therapy
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 1:1 ratio. Participants will receive two intravenous infusions of 3BNC117-LS (dosed at 30 mg/kg) and 10-1074-LS (dosed at 10 mg/kg) or placebo at weeks 0 and 20. Participants will remain on ART during the study.

The documentation of partner sterility can come from the site personnel s review of medical records, medical examination and/or semen analysis, or medical history interview provided by the participant or the partner. Self-reported documentation of reproductive potential should be entered in the source documents.
