Abstract

e14677 Background: Malignant mesothelioma (MM) is an aggressive malignancy of the pleura with limited therapeutic options, and is associated with a poor prognosis. EGFR is known to be highly over-expressed in mesothelioma with reported EGFR overexpression between 44 to 97%. We have investigated an anti-EGFR antibody (ABT-806), which is tumor specific and robustly inhibits EGFR-expressing tumors. We have previously shown that ABT-806 ADCs demonstrate potent anti-tumor activity in 806 immunohistochemistry (IHC) positive MSTO-211H MM cell line xenograft model. We present data in MM using ABT-806 novel ADCs [ABT-414 (ABT-806- monomethyl auristatin F), ABBV-221 (ABT-806- monomethyl auristatin E)..
