Gene Profile in EGFRm Locally Advanced or Metastatic NSCLC Patients Post Osimertinib 1L Treatment Failure: A Real-world, Multi-center Study (GPS)

AstraZeneca·interventional·Posted Feb 1, 2022·Updated Sep 11, 2025

In Brief

A Phase 4 clinical trial evaluating Gene Profile explore for Advanced NSCLC. Completed, enrolled 182 participants across 16 sites.

Detailed Summary

Although some small sample studies have reported the possible resistance mechanisms of Osimertinib in the first-line treatment, it is still an urgent need to explore the whole gene profile in EGFRm advanced NSCLC patients post Osimertinib 1L treatment by paired tissue and plasma to guide subsequent treatment strategy. Thus, the gene profile post Osimertinib 1L treatment in tissue and plasma may help to guide the following treatment. Participants will be required to provide paired tissue and whole blood after disease progression following 1L Osimertinib. 200 tissue samples and 200 whole blood samples will be used to detect gene alteration by NGS, respectively. 200 tissue samples will be used to detect pathological transformation by IHC. Approximately 80-100 tissue samples will be used to test MET overexpression by MET IHC and MET amplification by FISH respectively. Approximately 80-100 whole blood samples will be used to test MET amplification by ddPCR.

Interventions

Gene Profile exploregenetic

The tissue and blood sample for this genetic research will be obtained from the participants at baseline(disease progression after 1L Osimertinib). Paired tissue and whole blood sample should be collected per participant for genetics during the study.
