Title:
THERAPEUTIC AGENT FOR LUNG CANCER THAT HAS ACQUIRED EGFR-TKI RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2017/200016
Kind Code:
A1
Abstract:
A drug having as the active ingredients brigatinib, an AP26113 analog, and a compound represented by AZD3463, which are ALK inhibitors, was discovered to be effective in non-small cell lung cancer having a point mutation in EGFR C797S that has acquired resistance to chemotherapeutics. Furthermore, a remarkable suppressive effect on tumor growth is demonstrated by using an anti-EGFR antibody in combination. This agent serves as a therapeutic agent that is effective in non-small cell lung cancer having resistance to gefitinib, which is a first generation therapeutic agent, and osimertinib, which is a third generation therapeutic agent.
