Immunodeficient NSG and NSGS mice only (single-dose, human CD34+ cell xenograft)
“The non-clinical safety programme conducted with Lenti-D LVV transduced human CD34+ HCSs consists of two single-dose toxicology studies performed in NSG and NSGS immune-incompetent mice.”
Not conducted (acceptable given product characteristics and safety profile)
“Reproductive and developmental toxicity studies were not performed for eli-cel which is acceptable based on the product characteristics and safety profile.”

Surrogate used in
Yes: ALDP-deficient AMN patient CD34+ HSCs used as surrogate product in in vitro pharmacology
“These ALDP-deficient AMN CD34+ HSCs were used as a surrogate product in the in vitro pharmacology studies to demonstrate vector integration, ALDP production, and correction of VLCFA metabolism.”
