In vivo CAR T-cell generation in non-human primates using lentiviral vectors displaying a multi-domain fusion ligand

Chimeric antigen receptor (CAR) T-cell therapies have demonstrated transformative efficacy in treating B-cell malignancies. However, high cost and manufacturing complexities hinder their widespread use. To overcome these hurdles, we have developed the VivoVecTM platform, a lentiviral vector capable of generating CAR T-cells in vivo. Here we describe the incorporation of T cell activation and costimulatory signals onto the surface of VivoVecTM particles (VVPs) in the form of a multi-domain …
