Intravenous delivery of CAR T cells does not significantly prolong survival in mice. a U87vIII cells (5 × 10³) were implanted orthotopically into NSG mice and treated post-implantation with intravenous (IV) effector cells. b Antitumor responses produced by CART-EGFRvIIIΔPD-1 in vivo. Survival curves were estimated for each group using Kaplan–Meier product-limit estimation. Primary comparative analyses of the curves for each group were performed using the log-rank test. c Bioluminescence imaging of U87vIII tumor growth over time, n = 5 mice
