Of the 13 pts who had centrally confirmed EGFR mutation and MET-amplification (6 with GCN ≥10, and 7 with GCN ≥5 but < 10), 8 had PR (response rate 61.5%; 5 confirmed PR), and 4 had SD. Among the 8 pts achieving PR, there were 4 with GCN ≥10, and 4 with GCN ≥5 but < 10....HS-10241 in combination with almonertinib was well tolerated, and showed encouraging antitumor activity in treatment of advanced NSCLC with EGFR mutation and MET amplification following prior EGFR-TKI, whether MET GCN ≥10 or MET GCN ≥5 but < 10.
