No relevant species; in vitro and syngeneic mouse surrogate CAR-T only
“Since the anti-CD19 scFv utilised for KTE-X19 does only recognise human CD19, a murine surrogate model was engineered for non-clinical proof-of-concept studies in immune competent mice.”
scFv recognizes only human CD19; no relevant animal model
“Similar as the pharmacology evaluation, also the non-clinical safety evaluation of KTE-X19 has been severely limited due to the lack of a relevant animal model.”
Yes: anti-murine CD19 CAR (1D3 scFv) T cells in syngeneic lymphoma mice
“This surrogate model used an anti-murine CD19 CAR construct that was similar to KTE-X19 with the exception of the scFv, which has been derived from the 1D3 mAb recognizing murine CD19.”
