Kresladi: which tox species, and why?
marnetegragene autotemcel · ITGB2 (LVV, ex vivo HSC)
Species
Mouse only (CD18HYP/CD18KO disease models, recipient mice, NSG mice); no large-animal tox
“The applicant also used surrogate Lin- HSPCs transduced with the Chim-CD18-WPRE LV transplanted into recipient mice for their definitive in vivo toxicology and BD studies.”
Why that species
CD18-deficient mice mimic LAD-I phenotype (impaired neutrophil migration); patient CD34+ cells unavailable
“CD18HYP and CD18KO mice have deficient CD18 expression and impaired neutrophil migration and inflammatory responses similar to LAD-I patients.”
Surrogate molecule
Yes: murine Lin- HSPCs transduced with clinical vector; healthy-donor human CD34+ cells in NSG mice
“The final clinical product and source material was not used in the nonclinical studies summarized in this memo due to feasibility issues obtaining sufficient CD34+ HSCs from LAD-I patients.”
