What is vedolizumab?
Vedolizumab is currently approved by the U.S. 2(FDA) under the brand name Entyvio for the treatment of ulcerative and Crohn’s disease.3 Vedolizumab is also being studied as an to treat HIV .
As an investigational HIV drug, vedolizumab belongs to a group of drugs called α₄β₇ integrin antagonists. α₄β₇ integrin antagonists block an immune cell 4called α₄β₇.3 The α₄β₇ receptor is thought to have an important role in directing HIV into gut tissues.
Researchers are currently studying whether vedolizumab can help people with HIV maintain control of theirlevels.5–7
Select clinical trials of vedolizumab
Study Name: NCT03577782
Status: This study has been completed.
Purpose: The purpose of this study was to evaluate the safety of vedolizumab and whether vedolizumab plus (ART) could help people who had never taken HIV medicines control their viral load levels during an of ART.2,5,8
Selected Study Results: Results presented at GeSIDA 2019 (abstract PO-48) showed that although vedolizumab was safe and well tolerated when given in combination with ART to participants in the early stages of HIV infection, it was unable to substantially control viral load levels after participants underwent an analytical treatment interruption of ART.8
Study Names: HAVARTI; NCT03147859
Status: This study is currently recruiting participants.
Purpose: The purpose of this trial is to evaluate vedolizumab’s safety and ability to control viral load levels in individuals with undergoing an analytical treatment interruption of ART.6
Selected Study Results: Results presented at CROI 2019, showed that vedolizumab given at two different 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 after treatment interruption of ART. Notably, the higher dose of vedolizumab appeared to have a significantly greater effect on reducing compared with the lower dose of vedolizumab.9
Study Names: EHVA T02/ANRS VRI07; NCT04120415
Status: See the ClinicalTrials.gov record for this study’s status.
Location: Not available
Purpose: The purpose of this study is to evaluate the ability of vedolizumab given with and without the MVA HIV-B in controlling viral load levels in people undergoing an analytical treatment interruption of ART.7
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.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.
In this Phase 2 study, ten participants were enrolled, and six participants completed 24 weeks of treatment with vedolizumab plus ART, followed by interruption of treatment. Vedolizumab was reported as being well tolerated. No serious side effects occurred throughout the study period.5,8
In this Phase 2 study, eight adults with HIV receivedinfusions 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 each occurred in one participant.6,9
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.
