Orthotopic brain tumor models were established by inoculating 43 (EGFRwt expressing glioma cell), D270MG (EGFRwt and EGFRvIII espressing glioma cells), and NR6M (EGFRvIII expressing fibroblast cells) intracranially in the immunocompromised mice. CED was achieved by inserting a cannula into the brain tumor site, which in turn was connected to a subcutaneous osmotic pump delivering the immunotoxin into the tumor microenvironment. The antitumor efficacy was evaluated by Kaplan-Meier survival analysis.
Comparison of MST among different groups in three xenograft mouse models
In the orthotopic brain tumor mouse models, the D2C7-IT therapy via CED exhibited a robust therapeutic potential in treating brain tumors expressing EGFRwt, EGFRvIII, and both EGFRwt and EGFRvIII.
