About
The main purpose of this study is to see if it is safe to give the study antibodies (3BNC117-LS-J and 10-1074-LS-J) by intravenous infusion to people with HIV (PWH), and to see if they cause any side effects. In addition, to see how the study antibodies affect the level of HIV in the blood when participants are not taking regular HIV treatment for an extended period. This extended period of not taking regular HIV treatment is called an analytical treatment interruption (ATI).

Inclusion criteria
Step 1:
Ability and willingness of participant to provide informed consent.
HIV-1 infection, documented by:
Any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry AND
Confirmed by one of the following:
On stable suppressive ART for at least 96 weeks prior to study entry. [NOTE: ART interruptions of up to 7 days occurring ≥90 days prior to study entry are acceptable. Within- and between-class changes in ART within the year prior to study entry are acceptable.]
Plasma HIV-1 RNA levels of <50 copies/mL for at least 96 weeks prior to study entry at any licensed local laboratory or Network-approved non-US laboratory that is VQA certified.
[NOTE: Two "blips" (i.e., plasma HIV-1 RNA >50 and <400 copies/mL) are allowed if each blip is preceded and followed by values <50 copies/mL. At least one viral load measurement in greater than 56 days and within 48 weeks prior to the entry visit and another viral load within 56 days prior to the entry visit must be available for review. ]
CD4+ cell count >450 cells/µL obtained within 56 days prior to study entry at any Network-approved non-US laboratory that is IQA certified.
The following laboratory values obtained within 56 days prior to study entry by any Network-approved non-US laboratory that is EQA certified:
For participants who can become pregnant (i.e., participants assigned female sex at birth who have not been post-menopausal for at least 24 consecutive months, who have had menses within the preceding 24 months, or who have not undergone surgical sterilization, specifically hysterectomy and/or bilateral oophorectomy or bilateral salpingectomy), negative serum or urine pregnancy test within 24 hours prior to Step 1 entry (Day 0) by a Network-approved non-US laboratory that is EQA certified. [NOTE: Participant-reported history is acceptable documentation of hysterectomy and bilateral oophorectomy, tubal ligation, tubal micro-inserts.]
Participants who can become pregnant must agree to use two methods of contraception, one of which must be from the highly effective methods for contraception listed below. Barrier methods of contraception are permitted for the second method of contraception. Contraception must be used from 10 days prior to study entry and participants must agree to use contraception for 36 weeks after receiving study treatment, and until ART is reinitiated and viral suppression is achieved. Acceptable methods of contraception include:
Participants who can impregnate (i.e., individuals assigned male sex at birth who have not undergone a sterilizing procedure) a partner and who are engaging in sexual activity that could lead to pregnancy must agree to use condoms from 10 days prior to study entry and for 36 weeks after receiving study treatment to avoid impregnating a partner.
Willingness to use barrier protection (i.e., external or internal) for all sexual activity during ATI and until viral suppression is achieved after re-starting ART.
Willingness to not participate in other research studies of investigational drugs while on this study.
Willingness to provide a specimen for a genetic test (HLA Typing).

Exclusion criteria
Step 1:
History of any AIDS-defining illness prior to study entry. [NOTE: History of treated and resolved pulmonary TB will not be exclusionary.]
Known nadir CD4+ cell count <200 cells/µL. [NOTE: If laboratory reports or clinical notes are not available, then participant recall is acceptable for nadir CD4 T-cell count.]
Any clinically significant acute or chronic medical condition (such as autoimmune diseases or active tuberculosis), other than HIV infection, that in the opinion of the investigator would preclude participation.
Any history of an HIV-associated malignancy, including Kaposi's sarcoma, or any type of lymphoma or virus-associated cancers.
History of Progressive Multifocal Leukoencephalopathy (PML).
Active or recent non-HIV-associated malignancy requiring systemic chemotherapy or surgery within 36 months prior to study entry or for whom such therapies are expected in the subsequent 12 months. [NOTE: Minor surgical removal of localized skin cancers (squamous cell carcinoma, basal cell carcinoma) is not exclusionary.]
Receipt of an NNRTI within 30 days prior to study entry.
Receipt of cabotegravir-LA IM, rilpivirine-LA IM, or other long-acting ARVs within 24 months prior to study entry.
Receipt of any standard-of-care (SOC) vaccines within 7 days prior to study entry.
Known resistance to all drugs within two or more ARV drug classes. [NOTE: M184V/I is an exception and should not be considered when assessing this criterion. Prior HIV resistance testing is not required.]
History of systemic corticosteroids (>14 days concurrent use), immunosuppressive anti-cancer or other immunosuppressive agents, interleukins, systemic interferons, systemic chemotherapy, or other medications considered significant by the investigator within the 24 weeks prior to study entry.
ART initiated during acute infection (defined as p24, HIV NAAT, or HIV RNA PCR positive, and negative or indeterminate HIV antibody testing).
Any history of receipt of therapeutic HIV vaccine or HIV monoclonal antibody therapy.
Participation in any clinical study of an investigational product within 12 weeks prior to study entry or expected participation in such a study while on A5416.
Known allergy/sensitivity or any hypersensitivity to components of either study agent or their formulation.
Breastfeeding.
Chronic hepatitis B or C infection as indicated by the presence of Hepatitis B surface antigen (HBsAg), hepatitis C antibody without documented history of prior treatment and clearance or virus RNA (HCV-RNA) or HCV antigen in blood at a Network-approved non-US laboratory that is EQA certified.
Current untreated or incompletely treated active tuberculosis disease or untreated latent tuberculosis infection. [NOTE: Individuals who are on treatment for latent TB with at least 4 weeks of treatment completed are not excluded.]
History of or current clinical atherosclerotic cardiovascular disease (ASCVD), as defined by 2013 American College of Cardiology/American Heart Association (ACC/AHA) guidelines, including a previous diagnosis of any of the following:
Diagnosis of cirrhosis.
Diagnosis of untreated syphilis, gonorrhea, or chlamydia. [NOTE: Individuals who began treatment at least 3 days prior to study entry for any of the above are not excluded.]
