“…Enapotamab vedotin induces potent antitumor activity in an osimertinib-resistant NSCLC PDX model in vivo. Finally, we assessed the in vivo antitumor activity of enapotamab vedotin in the AXL-expressing PDX model LCx-MR007, derived from a patient with NSCLC who acquired resistance to osimertinib in the clinic (27,28). Although osimertinib had no effect on tumor growth, tumor regression was observed in mice treated with enapotamab vedotin at a dose of 4 mg/kg ( Figure 6A).…”
