The authors would like to correct Figure 4b of this article. The statement in the figure legend that reads “The epidermal growth factor receptor variant III (EGFRvarIII) cannot bind cetuximab or matuzumab” is incorrect. Wu and colleagues1 have shown that cetuximab does bind EGFRvarIII. Furthermore, Li and colleagues2 have demonstrated that X-ray crystal structure data of the cetuximab–EGFR complex show that cetuximab recognizes an epitope that is present in EGFRvarIII. Matuzumab also binds EGFRvarIII (W. Wels and C. Hartmann, unpublished observations).
