Can a dose increase control lung cancer that Isn't shrinking?
NCT ID NCT07298148
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a higher dose (160 mg) of the drug firmonertinib can improve outcomes for people with advanced EGFR-mutant non-small cell lung cancer whose tumors have stayed stable but not shrunk after 8 weeks on the standard 80 mg dose. About 28 adults aged 18-75 with no prior treatment will take the higher dose daily. The main goal is to see if more tumors shrink or disappear.
