Show all 18Show fewer
  • Succeeding viral levels return to levels below the limit of detection on subsequent testing.
  • Willingness to undergo ATI.
  • Laboratory values within pre-defined limits at screening:
  • Absolute neutrophil count >1,000/mm^3.
  • Hemoglobin levels >10.0 g/dL for men and >9.0 g/dL for women.
  • Platelet count >100,000/mm^3.
  • Prothrombin time (PT) and partial thromboplastin time (PTT) <1.5 upper limit of normal (ULN).
  • Estimated or a measured creatinine clearance rate of greater than or equal to 50 mL/min as determined by the NIH Clinical Center laboratory.
  • AST and ALT levels of <2.5 x ULN.
  • Willingness to have samples stored for future research.
  • Reproductive Risks
  • Contraception: The effects of VRC01 on the developing human fetus are unknown. For this reason, men and women of childbearing potential must agree to use adequate pregnancy prevention per the investigator. This includes highly reliable established lifestyle of complete abstinence of potentially reproductive sexual activity, or use of BOTH a long term hormonal or barrier (e.g. implant, depot injection, IUD in female participant or female partner of participant) method of contraception that is fully effective prior to dosing, COMBINED WITH a barrier method (male or female condom) for all potentially reproductive sexual activity. Pregnancy prevention must be maintained as effective and practiced continuously for the duration of study participation. Females of childbearing-age must have a negative pregnancy test result prior to receiving VRC01. During the course of the study, if a female participant, or the partner of a male participant suspects or in fact becomes pregnant, the effected participant should inform the study staff immediately, as well as the woman's primary care physician. Subjects must use safe sex practices during the trial, and particularly during the ATI phase, when risk of transmission of HIV may be increased.

Who cannot join

  • Chronic hepatitis B, as evidenced by a positive test for hepatitis B surface antigen (HBsAg), or chronic hepatitis C virus (HCV) infection, as evidenced by a positive test for HCV RNA. Subjects with a positive test for HCV antibody and a negative test for HCV RNA are eligible.
  • Documented virologic failure to >1 cART regimen.
  • HIV immunotherapy or vaccine(s) received within 1 year prior to screening.
  • Any licensed or experimental non-HIV vaccination (e.g., hepatitis B, influenza, pneumococcal polysaccharide) received within 2 weeks prior to study enrollment.
  • Receipt of other investigational study agent within 28 days of enrollment.

  • Systemic immunosuppressive medications received within 3 months prior to enrollment (Not excluded: corticosteroid nasal spray or inhaler; topical corticosteroids for mild, uncomplicated dermatitis; or oral/parenteral corticosteroids administered for non-chronic conditions not expected to recur [length of therapy less than or equal to 10 days, with completion in greater than or equal to 30 days prior to enrollment]).
  • History or other clinical evidence of:
  • Significant or unstable cardiac disease (e.g., angina, congestive heart failure, recent myocardial infarction).
  • Severe illness, malignancy, immunodeficiency other than HIV, or any other condition that, in the opinion of the investigator, would make the subject unsuitable for the study.
  • Active drug or alcohol use or any other pattern of behavior that, in the opinion of the investigator, would interfere with adherence to study requirements.
  • Breast-feeding.

About this study

Official title: An Exploratory, Open-Label Study of VRC-HIVMAB060-00-AB (VRC01) in Subjects With Chronic HIV Infection Undergoing Analytical Treatment Interruption

Background:

  • A combination of daily drugs (called cART) can keep human immunodeficiency virus (HIV) very low for a long time. But cART can lose effectiveness and cause permanent side effects. If treatment stops, HIV levels go up again. Researchers want to see if a new product can control HIV levels when a person is off cART.
Read more

Objective:

  • To see if the new product VRC01 is safe and can control the HIV level in the blood when a person is not taking cART.

Eligibility:

  • Adults ages 18-65 with HIV who are willing to interrupt their treatment for at least 24 weeks.

Design:

  • Participants will be screened with:
  • Physical exam
  • Medical history
  • Heart tests
  • Blood and urine tests.
  • Their HIV drugs may be switched. They will keep taking them until a few days after Visit 1.
  • Visit 1: Repeat screening procedures.
  • Participants will also have genetic testing and leukapheresis. For this, blood will be removed through a needle in one arm and circulated through a machine that removes white blood cells. The rest of the blood is returned through a needle in the other arm.
  • They will get the first study drug dose through a thin tube in an arm vein for about 1 hour.
  • For 24 weeks, participants will have 16 visits. They will have blood drawn every visit. At some visits they will repeat the screening procedures and get another VRC01 dose. They may have another leukapheresis.
  • Four weeks after the last dose, participants will restart their cART. For 20 weeks, they will have monthly visits to repeat the screening procedures and discuss new symptoms.
Read the detailed description

Recent advances in antibody cloning technologies have led to the discovery of a number of highly potent, HIV-specific, broadly neutralizing monoclonal antibodies from B cells of HIV-infected individuals. It has been shown that certain broadly neutralizing HIV-specific antibodies can prevent acquisition of the virus, suppress viral replication, delay and/or prevent plasma viral rebound following treatment interruption in Simian Immunodeficiency virus (SIV)-infected animals and block cell-to-cell transmission of laboratory-adapted HIV in vitro. However, it is unclear what in vivo effects these antibodies might have on plasma viral rebound in HIV-infected individuals following discontinuation of combination antiretroviral therapy (cART).

In this regard, it has been shown that virtually all infected individuals who initiated cART during the chronic phase of infection experience plasma viral rebound upon cessation of therapy. Current research on the treatment of HIV-infected individuals has been heavily focused on developing strategies aimed at achieving sustained virologic remission in the absence of cART. Thus, it is of great interest to investigate whether a potent HIV-specific monoclonal antibody, such as VRC01, can prevent plasma viral rebound in infected individuals upon discontinuation of cART. We propose to examine the effect of VRC01 on plasma viral rebound in HIV-infected individuals following analytical treatment interruption (ATI).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Grade 3 or Higher Adverse Events

    The primary endpoint was the number of grade 3 or higher adverse events, including serious adverse events, that were possibly related to VRC-HIVMAB060-00-AB (VRCO1).

    Measured: From the start of the initial infusion until up to 48 weeks.

Secondary outcomes (1)
  1. Subjects Who Met Criteria to Restart Antiretroviral Therapy

    The secondary endpoint was the number of subjects who met protocol defined virologic (sustained HIV RNA >1000 copies/mL by Abbott HIV RTPCR at 2 consecutive visits), immunologic (a confirmed >30% decline in CD4 cell count or an absolute CD4 cell count < 350 cells/mm3), or clinical criteria (HIV-related symptoms) to discontinue VRC01 infusions and restart Antiretroviral Therapy (ART).

    Measured: From Day 3 post initial infusion until up to 28 weeks.
