Human autologous T cells do not engraft in immunocompetent animals; no representative models
“Ide-cel comprises engineered human T cells, therefore there are no representative in vitro assays, ex vivo models, or in vivo models that can accurately address the toxicological characteristics of the human product.”
No surrogate; human ide-cel tested in NSG mice with human MM xenografts
“Rapid elimination of both subcutaneous and systemic tumours and increased survival was demonstrated in NSG mice with BCMA+ xenografts after a single dose of ide-cel.”
