What is 10-1074?

10-1074 is an investigational drug that is being studied as a possible strategy to treat people living with HIV. 10-1074 belongs to a group of drugs called broadly neutralizing antibodies (bNAbs).1

To learn how investigational drugs are tested during clinical trials, read the HIVinfo What is an Investigational HIV Drug? and HIV and 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.4,5

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.4,6,7

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.6,8

Researchers are also trying to find out if 10-1074 can prevent HIV infection in people who do not have the virus.2 This record focuses on the study of 10-1074 as a treatment for HIV.

Study Names: Tatelo Study; NCT03707977
Phase: 1/2
Status: This study has been completed.
Location: Botswana
Purpose: The purpose of this study was to evaluate the efficacy of 10-1074 and another investigational bNAb called VRC01LS in maintaining viral suppression in a group of children who had received early antiretroviral therapy (ART).9
Selected Study Results: Results presented at CROI 2022 showed that treatment with both 10-1074 and VRC01LS (given either individually or in combination) was generally safe and effective. Participants with a longer time on ART and bNAb overlap were more likely to succeed along with participants who enrolled earlier in the study and had favorable pre-intervention clinical and reservoir characteristics. There were no infusion reactions or severe side effects related to bNAb treatment.10

What side effects might 10-1074 cause?What side effects might 10-1074 cause?

What side effects might 10-1074 cause?

One goal of HIV research is to identify new drugs that have fewer side effects. In the Tatelo Study (NCT03707977) discussed under the previous section, results from early parts of the trial showed that one participant experienced a serious side effect (neutropenia) that was possibly related to study treatment. No participants experienced infusion reactions or life-threatening side effects related to single or dual bNAb administration, and no expedited side effects occurred with dual bNAb treatment.10,25,26

Because 10-1074 is still being studied, information on possible side effects of the drug is not complete. As testing of 10-1074 continues, additional information on possible side effects will be gathered.
