Abecma
idecabtagene vicleucel · BCMA CAR-TNot conducted (traditional); insertion site analysis of 20 clinical lots
Tecelra: genotox, carcinogenicity and repro: done or skipped?
afamitresgene autoleucel · MAGE-A4 TCR-T
Genotoxicity
Not conducted (no test models or relevant species); integration site analysis showed polyclonal products, no selective insertion
“Conventional genotoxicity studies were not conducted with afamitresgene autoleucel, due to the lack of appropriate test models and pharmacologically relevant species.”
Carcinogenicity
Not conducted (no relevant animal models for human TCR-engineered T cells)
“Afamitresgene autoleucel is a human TCR engineered T-cell product, therefore conventional carcinogenicity studies were not performed due to the lack of relevant animal models.”
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
Genomic insertion site analysis on products from five patients; no preferential integration near genes of concern
“A genomic insertion site analysis was performed on TECELRA products from five patients. There was no evidence for preferential integration near genes of concern.”
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.
Reproductive & developmental
Not conducted; theoretical testis/placenta risk (MAGE-A4 expression) judged mitigated by immune privilege, labeling, pharmacovigilance
“MAGE-A4 is known to be expressed in testes and placenta, and so there is a theoretical risk of embryotoxicity or toxicity to the testes.”
Safety pharmacology
Not conducted; no relevant animal models
“No safety pharmacology studies were conducted, as there are no relevant animal models for the nonclinical safety assessment of afamitresgene autoleucel.”
Genotox: Ames
Not conducted
“Conventional genotoxicity studies were not conducted with afamitresgene autoleucel, due to the lack of appropriate test models and pharmacologically relevant species.”
Genotox: in vitro mammalian
Not conducted
“Conventional genotoxicity studies were not conducted with afamitresgene autoleucel, due to the lack of appropriate test models and pharmacologically relevant species.”
Genotox: in vivo
Not conducted
“Conventional genotoxicity studies were not conducted with afamitresgene autoleucel, due to the lack of appropriate test models and pharmacologically relevant species.”
Carcinogenicity model
Not conducted; vector integration site profile similar to other lentiviral products, no greater insertional oncogenesis risk expected
“However, vector integration site analysis demonstrated that the insertion site profile for the product was similar to other lentiviral vector products and was not expected to represent a greater risk for the development of insertional oncogenesis.”
Carcinogenicity timing
Not conducted; no relevant animal models for a human TCR-engineered T-cell product
“Afamitresgene autoleucel is a human TCR engineered T-cell product, therefore conventional carcinogenicity studies were not performed due to the lack of relevant animal models.”
hERG / QT
Not conducted (no relevant animal models for safety pharmacology)
“No safety pharmacology studies were conducted, as there are no relevant animal models for the nonclinical safety assessment of afamitresgene autoleucel.”
