No relevant species; in vitro and NSG mouse xenograft only
“In particular, suitable animal models are not available for accurately assessing the non-clinical characteristics of a human cell-based product such as JCAR017.”
FMC63 scFv binds human CD19 only; no mouse or NHP cross-reactivity
“The results support that JCAR017 is specific for human CD-19 binding and lacks species cross-reactivity, in particular towards mouse and non-human primate.”
No surrogate; human product tested in immunodeficient xenograft mice
“The lack of conventional in vivo studies and the use of immune-deficient Raji Burkitt’s lymphoma-bearing NOD/SCID IL-2Rγnull mice model are justified and appropriate to investigate autologous cell-based products.”
