Phase II Trial of Dasatinib for Patients with Acquired Resistance to Treatment with the Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors Erlotinib or Gefitinib

摘要

IntroductionDual inhibition of SRC and EGFR -dependent pathways may overcome acquired resistance to EGFR-TKIs for patients with lung adenocarcinoma with EGFR mutations. The SRC-inhibitor dasatinib demonstrates anti-tumor activity in gefitinib-resistant cells lines and xenografts. Dasatinib is tolerable for patients with advanced non-small cell lung cancer, and in combination with erlotinib.
