Genotoxicity
Not conducted; literature review of retroviral-transduced T-cell transformation risk instead
“No in vitro and in vivo genotoxicity and carcinogenicity assessments for KTE-C19 were conducted.”
Carcinogenicity
Not conducted; literature suggests T cells resistant to retroviral transformation
“The data suggest that T cells are relatively resistant to malignant transformation by retroviral vectors.”
Instead of carcinogenicity
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
Instead of genotoxicity
Published literature on resistance of mature mouse T cells to γ-retroviral insertional transformation
“A detailed evaluation of published literature was provided that addressed the resistance of mature mouse T cells to transformation induced by genomic integration of γ-retroviral vectors.”
DRG histopathology
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.

Genotox: Ames
Not conducted
“No in vitro and in vivo genotoxicity and carcinogenicity assessments for KTE-C19 were conducted.”
Genotox: in vitro mammalian
Not conducted
“No in vitro and in vivo genotoxicity and carcinogenicity assessments for KTE-C19 were conducted.”
Genotox: in vivo
Not conducted
“No in vitro and in vivo genotoxicity and carcinogenicity assessments for KTE-C19 were conducted.”
Carcinogenicity model
Not conducted; literature review suggests T cells relatively resistant to retroviral malignant transformation
“To address the risk of retroviral vector insertional mutagenesis and potential carcinogenicity/tumorigenicity the applicant performed a review of published nonclinical and clinical information reported for T cells transduced with retroviral vectors. The data suggest that T cells are relatively resistant to malignant transformation by retroviral vectors.”
Carcinogenicity timing
Not conducted; literature review on retroviral-vector T-cell transformation submitted instead
“No in vitro and in vivo genotoxicity and carcinogenicity assessments for KTE-C19 were conducted. To address the risk of retroviral vector insertional mutagenesis and potential carcinogenicity/tumorigenicity the applicant performed a review of published nonclinical and clinical information reported for T cells transduced with retroviral vectors.”
