Analysis of Biological Characteristics of Advanced ALK-rearranged NSCLC

Summary

BioEXALK is a prospective study evaluating the biological characteristics of advanced ALK-rearranged NSCLC treated with next generation TKIs in first line, included in the national EXPLORE ALK cohort (GFPC 03-2019), a non-interventional, national, multi-center cohort of ALK-rearranged NSCLC patients. BioExALK study will be proposed to every patient included in the Explore ALK GFPC 03-2019 study. Biological analysis will be performed on tumor tissue at diagnosis and at the time of disease progression when available and on circulating tumor DNA (ctDNA). For plasma testing, after obtained patient consent, blood samples will be taken and analyzed at the Léon Bérard Center (Lyon). Biological analysis on tissue obtained at diagnosis and at disease progression will be collected and be sent for centralized analysis to the Rouen University Hospital.
