Crizotinib is a first-generation ALK tyrosine kinase inhibitor (ITK-ALK). It is the standard first-line treatment for patients with advanced NSCLC with ALK gene rearrangement. Alectinib, ceritinib and brigatinib are second-generation ITK-ALK. They have been shown to be effective in the first line of treatment in randomized trials. Alectinib has shown superiority to crizotinib as the first line of treatment in three randomized therapeutic trials, positioning this ITK-ALK as the treatment of choice in first-line treatment. Despite the effectiveness of these new treatments, all patients will virtually experience a relapse. There is no data on second-generation TKI-ALK resistance mechanisms when given as first-line treatment and the best therapeutic strategy for progression is undefined.

Layout table for eligibility information
Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Signed Written Informed Consent:
Subjects must have signed and dated an IRB/IEC approved written informed consent form in accordance with regulatory and institutional guidelines. This must be obtained before the performance of any protocol related procedures that are not part of normal subject care.
Subjects must be willing and able to comply with scheduled visits, treatment schedule, and laboratory testing
Patients with histologically or cytologically confirmed locally advanced not eligible to a local treatment or metastatic NSCLC (Stage IIIB or IV accordingly to 8th classification TNM, UICC 2015) that carries an ALK rearrangement, as determined by the molecular biology platform of the investigator by FISH assay or by Immunohistochemistry (IHC), or Next Generation Sequencing (NGS) or RNA sequencing approach .
Disease Status Requirements: Disease progression meeting RECISTv1.1 after first-line alectinib or brigatinib only. No prior chemotherapy is allowed in the metastatic disease setting.
Tumor Requirements: All Patients must have at least one measurable target lesion according to RECIST v1.1. In addition, patients with asymptomatic and neurologically stable CNS metastases (including patients controlled with stable or decreasing steroid use within the last week prior to study entry) will be eligible. The brain metastases may be newly diagnosed after disease progression with alectinib or brigatinib or be present as progressive disease after surgery, whole brain radiotherapy or stereotactic radiosurgery (see Exclusion Criterion for the lapsed time period required between the end of radiotherapy and study entry). Patients who have leptomeningeal disease (LM) or carcinomatous meningitis (CM) will be eligible if the LM/CM is visualized on MRI or if documented baseline cerebral spinal fluid (CSF) positive cytology is available and asymptomatic and neurologically stable (including patients controlled with stable or decreasing steroid use within the last week prior to study entry).
Tumor Sample Requirement: Tumour biopsy sampling on fresh tissue (FFPE blocks required) at time of progression on first-line TKI is mandatory. Tumour biopsy should be exploitable for molecular analysis. If the tumour biopsy is not exploitable, the inclusion will be allowed if two blood samples are provided for tumoral cfDNA analysis. The Sponsor will monitor a posteriori the exploitability of provided tumour biopsies and will investigate the impossibility to perform or repeat tissue tumor sampling.
