Testing Osimertinib as a Treatment for Lung Cancers With an EGFR Exon 20 Change

Is NCT03191149 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies Osimertinib for advanced lung non-small cell carcinoma.

Phase 2RecruitingNational Cancer Institute (NCI)NCT03191149Data as of May 2026

Treatment: OsimertinibThis phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
