– About 10%-25% of patients with epithelial growth factor receptor–(EGFR) mutant non–small cell lung cancer (NSCLC) have tumors with either MET amplification or another MET-based mechanism that leads to drug resistance.

In the TATTON trial, investigators are evaluating a combination of the EGFR-targeted tyrosine kinase inhibitor (TKI) osimertinib (Tagrisso) with savolitinib, an investigational MET inhibitor, for safety and activity against MET-driven NSCLC in patients with disease that has progressed on one or more prior EGFR-targeted agents.

In a video interview at the annual meeting of the American Association for Cancer Research, Lecia Sequist, MD, from the Massachusetts General Hospital Cancer Center in Boston, discusses early results with the osimertinib/savolitinib combination in patients with disease progression after a first and/or second-generation EGFR TKI, or after a third-generation agent.

Dr. Sequist said results of TATTON suggest that it may be possible to overcome MET-driven drug-resistance mechanisms.

The TATTON trial is sponsored by AstraZeneca. Dr. Sequist reported serving as an advisory board member and receiving research support and honoraria from the company.
