Axicabtagene ciloleucel (Yescarta; KTE-C19; BLA 125643) represents the one-hundred-fourth mechanism class in the Glyphward portfolio: the first CD28-costimulated gammaretroviral CD19 CAR-T cell therapy for large B-cell lymphoma (LBCL) ever FDA approved (BLA 125643 October 18 2017; R/R DLBCL/PMBCL/TFL after ≥2 prior lines).
