A critical question for cancer therapy: what new targets exist?

ABSTRACT: Designing molecular targeted therapy with high specificity based on novel tumor biomarkers is a high priority in lung cancer research. Several molecular aberrations have been already identified in non-small cell lung cancer (NSCLC), with subsequent development of drugs targeted to these aberrations. A more recent actionable target is MET, a multifaceted receptor tyrosine kinase which frequently interacts with other key oncogenic tyrosine kinases including epidermal growth factor receptor (EGFR) and ERBB3 leading to resistance to anti-EGFR therapies. However a phase III trial enrolling only patients with MET-positive tumors was stopped in early March due to futility since there was no evidence that the addition of onartuzumab to erlotinib has any positive effect. From the results of the MET lung phase III trial, we provide new pieces of information that can contribute to further preclinical validation and also be part of the armamentarium for clinical translational research.
