About this trial

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.

Patients included will be required to sign an informed consent form to collect blood samples (liquid biopsy) and tissue biopsy when available at progression on amivantamab;

Disqualifiers
