What is VRC01?

VRC01 is an investigational drug that is being studied as a possible strategy to treat people living with HIV. VRC01 belongs to a group of HIV drugs called broadly neutralizing antibodies (bNAbs).3

To learn how investigational drugs are tested during clinical trials, read the HIVinfo What is an Investigational HIV Drug? and HIV/AIDS Clinical Trials fact sheets.

How do broadly neutralizing antibodies work?

Antibodies are proteins that the immune system makes to fight infection. A person with HIV produces specific antibodies against HIV. However, most of these antibodies do not stop HIV from multiplying in the body.5,6

Some people with HIV naturally produce rare types of HIV antibodies called broadly neutralizing antibodies (bNAbs). bNAbs are powerful antibodies that can work against different HIV strains. bNAbs can block HIV from entering healthy cells and activate other immune cells to help destroy infected cells.5,7,8

Researchers are investigating whether giving bNAbs to people with HIV can help them maintain undetectable levels of HIV without the need for daily antiretroviral therapy. Additionally, some bNAbs are being studied because they may be able to reduce the size of the latent HIV reservoir.7,9

Researchers are also trying to find out if VRC01 can prevent HIV infection in people who do not have the virus.4 This record focuses on the study of VRC01 as a treatment for HIV.

Study Names: Tatelo Study; NCT03707977
Phase: 1/2
Status: This study is currently recruiting participants.
Location: Botswana
Purpose: The purpose of this study is to evaluate the efficacy of VRC01LS and the investigational bNAb 10-1074 in maintaining viral suppression in children receiving early treatment.10


Study Names: RV 397; NCT02664415
Phase: 2
Status: This study has been completed.
Location: Thailand
Purpose: The purpose of this study was to evaluate the safety of VRC01 and efficacy of VRC01 in preventing viral rebound in participants undergoing a structured treatment interruption of ART.11

For more details on the studies listed above, see the Health Professional version of this drug summary.

Additional studies investigating HIV treatment with VRC01 or a long acting form of VRC01 (called VRC01LS) have been or are being conducted. Some of these studies include:
  • NCT02591420: A Phase 1 study evaluating the safety and antiviral effects of VRC01 when given alone and when given with ART in adults with early acute HIV infection. This study is currently recruiting participants.12
  • ACTG A5378 (NCT02840474): A Phase 1 trial that evaluated the safety and antiviral effects of VRC01LS and another long-acting bNAb called VRC07 523LS in adults with HIV who had never received ART. This study has been completed.13
  • NCT03831945: A Phase 1 trial evaluating whether the combination of VRC01 plus 10-1074 can control viral load levels in virologically suppressed adults undergoing structured treatment interruptions of ART. This study is currently recruiting participants.14
  • IMPAACT 2008 (NCT03208231) and IMPAACT P1115 (NCT02140255): Two Phase 1/2 trials evaluating the use of VRC01 with ART in infants with HIV. NCT03208231 is ongoing but not recruiting participants. NCT02140255 is currently recruiting participants.15,16
What side effects might VRC01 cause?What side effects might VRC01 cause?

What side effects might VRC01 cause?

One goal of HIV research is to identify new drugs that have fewer side effects. In the RV 397 (NCT02664415) study discussed under the previous question, one participant dropped out of the study because of a severe side effect (hives) that occurred during their first dose of VRC01. Other side effects that occurred with intravenous infusions of either VRC01 or placebo were mild, with the exception of one case of moderate infusion-site bruising in a participant receiving VRC01.11,17

Because VRC01 is still being studied, information on possible side effects of the drug is not complete. As testing of VRC01 continues, additional information on possible side effects will be gathered.

Some clinical trials may be looking for volunteer participants. Your health care provider can help you decide whether participating in a clinical trial is right for you. For more information, visit NIH Clinical Research Trials and You.
