Recombinant Humanized Antibody (h-R3) is capable of binding to EGFR, expressed in Chinese Hamster Ovary cells (CHO).
Figure 1 Immunohistochemistry analysis of expression of selected markers (Ki67 and FVIII) in tumor biopsies of a patient treated with h-R3 and radiotherapy before and on-week 3 (on–therapy).
EGFR expression was classified as 3 in all patients. Before treatment, Ki67 staining ranged from 42% to 65% (median, 57%). Proliferative activity decreased at week 3; Ki67 staining ranged from 0% to 29% (median, 16%).
