WCLC 2025: Final Analysis of Firmonertinib Monotherapy Data from Ph 1b Study in EGFR PACC Mutant NSCLC presented
“Our 16-month prolonged progression free survival with once daily oral firmonertinib monotherapy has been maintained with 16.5 months of median follow up and we are particularly encouraged by the CNS responses including CNS complete responses” said Bing Yao, Ph.D., Chairman and Chief Executive Officer of ArriVent. “Together this data reinforces the potential of firmonertinib to address key unmet needs in the global EGFR mutant NSCLC treatment landscape. Additionally, the rapid clearance of PACC ctDNA in frontline patients observed across a broad range of PACC mutations, including those with frequent, less frequent and compound PACC mutations, is consistent with the broad activity of firmonertinib in PACC mutant NSCLC. We expect to enroll the first patient in our global registrational ALPACCA Phase 3 trial in frontline PACC patients in the second half of the year.”
