savolitinib for treating locally advanced or metastatic non-small cell lung cancer (nsclc) patients

Conditions: Non-small Cell Lung Cancer Metastatic

Summary: treating non-small cell lung cancer (nsclc) patients with met exon 14mutations with savolitinib

this is a single-arm, multi-cohort, multi-center, open-label, phase iiib clinical study. the objective is to evaluate the efficacy and safety of savolitinib in the treatment of locally advanced or metastatic nsclc patients with met exon 14 mutations. the study involves a screening period, a treatment period and a follow-up period. there are 53 study sites initiated and enrolled 203 advanced or metastatic nsclc patients with met exon 14 mutations
