EGFR and neoplasm: Subcutaneous xenograft mouse tumor model/intravenous OV injection:OVs encoding single antibodies (targeting EGFR, VEGF, or FAP) inhibited tumor growth more rapidly (one xenograft model) or stronger (other xenograft model) than control virus. OVs encoding two antibodies resulted in strongest tumor growth inhibition, significantly superior to control virus; significance not reached in comparison to single antibody-encoding OVs (169).
