Broadly neutralizing antibody-derived CAR T cells reduce viral reservoir in individuals infected with HIV-1.

ABSTRACT: BACKGROUNDChimeric antigen receptor (CAR) T cells have emerged as an approach to treat malignant tumors. This strategy has also been proposed for the treatment of HIV-1 infection. We have developed a broadly neutralizing antibody-derived (bNAb-derived) CAR T cell therapy that can exert specific cytotoxic activity against HIV-1-infected cells.METHODSWe conducted an open-label trial of the safety, side-effect profile, pharmacokinetic properties, and antiviral activity of bNAb-derived CAR T cell therapy in individuals infected with HIV-1 who were undergoing analytical interruption of antiretroviral therapy (ART).RESULTSA total of 14 participants completed only a single administration of bNAb-derived CAR T cells. CAR T cell therapy administration was safe and well tolerated. Six participants d
