Product is species specific; NOD/SCID mice permit human T cell engraftment and GvHD readout
“The MM-TK DP is a species specific product and therefore standard carcinogenicity studies using rodents or non-human primates as described in the ICH guidelines are not appropriate.”
No surrogate; human MM-TK cells in NOD/SCID mice (one model with grafted human skin)
“NOD/SCID mice subcutaneously transplanted with human skin were also used so that the direct evaluation of allogeneic GvHD response against the grafted human skin could be observed.”
