To now fully assess the safety and efficacy profile of the PODO83 mAb in this preclinical humanized mouse model we have developed mouse metastatic tumor cell line expressing human PODXL and will evaluate the ability of PODO83 to inhibit tumor growth and metastasis while sparing normal tissues in vivo. The results from this study will help us advance PODO83 mAb as a safe and effective approach to treating the wide variety of cancer subtypes that express PODXL.
