About

EGFR mutation positive advanced NSCLC patients with CNS metastases were associated with poor prognosis. Furmonertinib showed promising CNS efficacy in doses of 80 mg orally once daily or higher in patients with EGFR T790M mutation positive NSCLC. This study aims to investigate the efficacy and safety of furmonertinib in the treatment of EGFR-sensitive mutation positive NSCLC patients with brain metastasis.

Full description

This study aims to prospectively observe the efficacy and safety of furmonertinib in the treatment of EGFR-sensitive mutation positive NSCLC patients with brain metastasis and will recruit about 30 patients in China.

Furmonertinib (AST2818) is a brain penetrant third generation EGFR TKI. In preclinical studies, the concentration of furmonertinib and its main active metabolite in the brain was higher than that in the plasma, indicating that furmonertinib had the potential to treat CNS metastases. Furmonertinib showed promising CNS efficacy in doses of 80 mg orally once daily in patients with EGFR T790M mutated NSCLC, the median CNS PFS was 11.6 months and 19.3 months in the 80 mg and 160 mg orally once daily group, and the CNS ORR was 65% and 85% in the 80 mg and 160 mg group.

This study will enroll the EGFR-sensitive mutation positive NSCLC patients with brain metastasis who are treated by furmonertinib, and the efficacy and safety data will be recorded.
