简要总结
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI) are effective therapies for advanced lung cancer patients bearing EGFR-activating mutations, but are not curative due to the invariable apparition of resistances. The investigator team have identified a new phenotype related to drug tolerance after EGFR-TKI treatment that shares several characteristics of a known process of Therapy-Induced Senescence (TIS), which could be a major event of drug tolerance in patients. Using cutting-edge technologies, patient-derived xenografts (PDX) and circulating tumor cells (CTC), the investigator team will perform an exhaustive characterization of the phenotypic and molecular changes associated with this drug-tolerant state in patients. Their results should lead to new therapeutic approaches to eliminate the reservoir of drug-tolerant cells and to prevent emergence of resistance mutations responsible for the relapse of patients.
详细描述
LUNG-RESIST is a translational, monocentric and prospective research study on 40 patients whose objective is to characterize Drug Tolerant Cell (DTC) type cells in patients with a NSCLC carrying an EGFR mutation and to discover and monitor potentials biomarkers involved in this mechanism of resistance to osimertinib. The study will be offered to patients, and for whom the therapeutic decision was decided collegially during multidisciplinary molecular meetings (molecular Tumor Board). Following informed consent, patients will be registered in a single cohort. In this study, treatment with osimertinib is not studied and will be delivered according to current recommendations
