What is vedolizumab?

Vedolizumab is currently approved by the U.S. Food and Drug Administration (FDA) under the brand name Entyvio for the treatment of ulcerative colitis and Crohn’s disease.3  Vedolizumab is also being studied as an investigational drug to treat HIV infection.2

As an investigational HIV drug, vedolizumab belongs to a group of drugs called α₄β₇ integrin antagonists. αβ integrin antagonists block an immune cell receptor called αβ.3 The αβ receptor is thought to have an important role in directing HIV into gut tissues.4

Researchers are studying whether vedolizumab can help people with HIV maintain control of their viral load levels.5,6 

To learn about 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.

Select clinical trials of vedolizumab

Study Name: NCT03577782

Phase: 2
Status: This study has been completed.
Location: Spain
Purpose: The purpose of this study was to evaluate the safety of vedolizumab and whether vedolizumab plus antiretroviral therapy (ART) could help people who were treatment-naive control viral load levels during an analytical treatment interruption of ART.2,5,7
Selected Study Results: Results presented at CROI 2022 showed that although vedolizumab was safe and well-tolerated, it had no substantial impact on viral remission after participants underwent an analytical treatment interruption of ART.8
Additional Published Material:


Study Names: HAVARTI; NCT03147859

Phase: 2
Status: This study is currently recruiting participants.
Location: Canada
Purpose: The purpose of this trial is to evaluate vedolizumab’s safety and ability to control viral load levels in individuals with chronic HIV infection undergoing an analytical treatment interruption of ART.6
Selected Study Results: Results presented at CROI 2019 showed that vedolizumab given at two different doses and administered both before and after an analytical treatment interruption of ART was generally safe. No drug-related severe side effects were reported. No participants had sustained viral suppression after treatment interruption of ART. Notably, the higher dose of vedolizumab appeared to have a significantly greater effect on reducing viral rebound compared with the lower dose of vedolizumab.9

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


A Phase 1 study (NCT02788175) evaluating the effectiveness of vedolizumab on controlling viral rebound in individuals undergoing an analytical treatment interruption of ART has also been completed, and results are available from Science Translational Medicine (2019).10

What side effects might vedolizumab cause?

One goal of HIV research is to identify new drugs that have fewer side effects. The following side effects were observed in some of the studies of vedolizumab listed above.

NCT03577782

In this Phase 2 study, ten participants were enrolled, and six participants completed 24 weeks of treatment with vedolizumab plus ART, followed by an analytical treatment interruption of ART. Vedolizumab was reported as being well tolerated. No serious side effects occurred throughout the study period.5,7,8

HAVARTI (NCT03147859)

In this Phase 2 study, eight adults with HIV received intravenous infusions of vedolizumab. Vedolizumab was administered both before and after an analytical treatment interruption of ART. No drug-related severe side effects were reported. Influenza and severe short-term hepatitis each occurred in one participant.5,9

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


Additional information on side effects known to be associated with vedolizumab can be found in the FDA-approved Full Prescribing Information for Entyvio.3
