Study summary

Background:

Recent studies have shown bNAbs may help remove cells that are infected with HIV (HIV reservoir) from the body and may also change how the immune system fights HIV.

Objective:

The purpose of this research study is to see if and when HIV levels in the blood (viral load) rise after the participant stops their HIV medication. We will also measure the highest number (peak) of the virus before each participant starts their HIV medications again. For most people treated with standard HIV medications, the HIV virus amount will increase within 2 to 4 weeks after stopping their HIV medications. This study is only open to participants who have taken part in an earlier study (MCA-1034 or NIH number 001037). In the earlier study, participants either received a combination of 3BN117-LS and 10-1074-LS (two anti-HIV monoclonal antibodies) OR received placebo (salt water). In this new study, researchers will compare the participants who received the antibodies to those who did not to see what effect the antibodies may have had on the HIV reservoir.

Researchers will also look at:

  • side effects people may have when they stop their HIV medications.
  • changes in the number of blood cells carrying inactive HIV (the HIV reservoir size).
  • the blood cells that can clear HIV before, following temporarily stopping, and after re-starting HIV medications.
  • how well HIV may be controlled after a participant stops their HIV medication.

Eligibility:

People aged 18 to 70 years with HIV who completed protocol MCA-1034 (NIH Study 001037).

Design:

Participants will be screened. They will have a physical exam. They will answer questions about their health. Blood samples will be taken.

Participants will stop their HIV medications for a period of time. They will have blood tests every 2 weeks and clinic visits every 4 weeks for 24 weeks to check their HIV levels and to make sure they are not having side effects. There will be strict safety rules for restarting HIV medications. Some participants whose HIV levels remain low at 24 weeks may continue without ART for another 24 weeks; they will have blood tests every 2 to 4 weeks.

Participants may undergo leukapheresis up to 3 times: Leukapheresis is a several hours long procedure in which blood is collected from a vein in one arm, processed through an attached machine, and then returned to the person through a vein in the opposite arm.

Participants will have 4 follow-up visits over 24 weeks after they restart ART.

Participants will remain in the study up to 18 months.

Read the detailed description

Study Description:

This is an exploratory study to evaluate virologic and immunologic parameters during analytical treatment interruption (ATI) in people

with HIV (PWH) who participated in protocol MCA-1034 (NIH # 001037), which evaluated HIV-1 reservoir dynamics in peripheral blood during combination bNAb therapy plus ART or ART alone. MCA-1034 participants will be invited to participate in this study after completing all MCA-1034 follow up visits. MCA-1034 treatment assignment will not be known at enrollment in this study until unblinding of MCA-1034 occurs. Under MCA-1034, participants will have received 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 while on standard ART and will have completed 80 weeks of follow up after the first antibody infusions. Participants will be eligible to enter this study from 12 to 24 weeks after the last MCA-1034 study visit.

Participants who enroll in this study will discontinue ART at study entry (week 0/day 0) and will be followed every other week until meeting pre-defined ART restart criteria. The ATI period will last up to 24 weeks (Step 1 weeks 0-24). Participants who do not meet ART restart criteria will be offered to remain off ART until meeting ART restart criteria for up to 24 additional weeks with monitoring every 4 weeks, unless HIV-1 RNA is >= 200 copies/ml when monitoring will occur every 2 weeks (Step 2 weeks 25-48; i.e. maximum ATI period of 48 weeks).

At the end of the ATI period, all participants will be advised to resume ART even if they have not experienced return of viremia. Participants who experience return of viremia and/or meet ART resumption criteria will be followed for 24 weeks after resuming ART.

Objectives:

Primary Objectives:

- To evaluate the kinetics of plasma viral rebound during ATI in PWH who participated in protocol MCA-1034 (NIH # 001037) and received combination bNAb or placebo during suppressive ART.

Secondary Objectives:

  • To evaluate the occurrence of adverse events following ART discontinuation.
  • To evaluate changes in HIV-1 reservoir size in peripheral blood prior to, following ATI and after re-initiation of ART.
  • To evaluate HIV-1 specific cellular immune responses prior to, following ATI and after re-initiation of ART.
  • To evaluate levels of immune exhaustion and immune activation prior to, following ATI and after re-initiation of ART.

Exploratory Objectives:

  • To evaluate the degree (magnitude) of plasma viral rebound during ATI in PWH who participated in protocol MCA-1034 (NIH # 001037) and received combination bNAb or placebo during suppressive ART.
  • To characterize the HIV-1 reservoir clonal composition in peripheral blood prior to, following ATI and after re-initiation of ART.
  • To characterize host HIV-1 specific humoral and cellular immune responses prior to, following ATI and after reinitiation of ART.
  • To genotypically and phenotypically characterize plasma rebound viruses.
  • To correlate virologic outcomes with bNAb sensitivity of reservoir proviruses.
  • To correlate virologic and immunologic outcomes with time to meeting ART restart criteria.

Endpoints: Primary Endpoint:

- The difference in the time to meet criteria to restart ART between protocol MCA-1034 bNAb and placebo recipients.

Secondary Endpoints:

  • The difference in peak plasma viremia from ART discontinuation to meeting ART restart criteria between protocol MCA-1034 bNAb and placebo recipients.
  • The occurrence of grade 3 or higher adverse events (AE) (including confirmed laboratory abnormalities) that are possibly, probably, or definitely related to ART discontinuation.
  • The occurrence of serious adverse events, regardless of relationship to ART discontinuation.
  • Change in the intact proviral reservoir size, measured by droplet digital PCR (ddPCR) or intact proviral deoxyribonucleic acid assay (IPDA) prior to, following ATI and after re-initiation of ART.
  • Changes in HIV-1 specific T cell immune responses in peripheral blood, measured by enzyme-linked immunospot (ELISpot) or intracellular cytokine staining (ICS) prior to, following ATI and after re-initiation of ART.
  • Changes in immune exhaustion and immune activation cellular or soluble markers by flow cytometry or by ELISA methods prior to, following ATI and after re-initiation of ART.

Exploratory Endpoints:

  • Clonal composition of the intact proviral reservoir before and after immunotherapy with 3BNC117-LS and 10-1074-LS during suppressive ART by quadruplex polymerase chain reaction (Q4PCR) or other appropriate assays that may become available prior to, following ATI and after re-initiation of ART.
  • HIV-1 transcriptional activity as determined by spliced and unspliced HIV-1 ribonucleic acid (RNA) in circulating total CD4+ T cells and/or other appropriate assays prior to, following ATI and after re-initiation of ART.
  • Changes in HIV-1 specific T cell immune responses in peripheral blood, measured by assays such as epitope mapping, proliferation and viral inhibition assays prior to, following ATI and after re-initiation of ART.
  • Changes in binding capacity and neutralizing activity of autologous antibody responses to pre-ATI and post-ATI proviruses and rebound plasma viruses.
  • Env sequencing and neutralization sensitivity of plasma rebound viruses to 3BNC117-LS, 10-1074-LS and autologous IgG by TZM/bl.
  • Correlation between bNAb sensitivity of baseline proviruses (i.e. MCA-1034 entry) and virological outcomes (e.g. time to meeting ART restart criteria and peak viremia during ATI).
  • Correlation between pre-ATI virological (e.g. proviral reservoir size and transcriptional activity) and immunological measures (e.g. magnitude, breadth and functionality of HIV-1 specific T cell immune responses, and autologous neutralization titers) and time to meeting ART restart criteria.

Terms in these criteria, in plain language(22)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

CD4 count

The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Reproductive potential

Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.

Criteria about it usually ask for contraception during the study and for a time after it.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
