Investigational drug(s) / intervention(s)

Blood sampling

Blood sampling: Blood samples (2\*10 mL on ethylenediaminetetraacetic acid (EDTA)) will be taken at time of disease progression and will be sent for central liquid biopsy ctDNA analysis.

Study summary

The goal of this prospective, interventional study is to evaluate the mechanisms of acquired resistance to amivantamab monotherapy in patients with advanced NSCLC with EGFR ins20. The main question it aims to answer is:

What are the mechanisms of acquired resistance to amivantamab monotherapy in this population of patients ? How anticipate the efficacy of subsequent systemic therapies ?

After this information session, the participant will be asked to sign the study informed consent. A blood samples (2\*10 mL on ethylenediaminetetraacetic acid (EDTA)) will be taken at time of disease progression and will be sent for central liquid biopsy ctDNA analysis. If available, tumor tissue will also be sent for DNA NGS analysis.
