Longitudinal analysis of lentiviral and retroviral chimeric antigen receptors' integration sites reveals distinct clonal evolutionary patterns
19 Feb 2025
Abstract excerpt
T-cell malignancies following chimeric antigen receptor (CAR) therapies are partly related to insertional mutagenesis, but the longitudinal evolution of CAR-integration sites (IS) remains understudied. We performed an IS analysis in blood from three tisagenlecleucel (lentiviral), one axicabtagene-ciloleucel and one brexucabtagene-autoleucel (gammaretrovirals) patient at peak expansion and 1-year follow-up. All...
