Human NSCLC xenografts (EGFR del19, L858R/T790M) in nude mice, including intracranial model
“Further, oral administration of lazertinib inhibited both SC and intracranial tumor growth and extended survival in a dual implantation NSCLC EGFR L858R/T790M mutant xenograft model in nude mice, suggesting lazertinib may have activity against brain metastases.”

Reviewer's view of the efficacy data
EMA: in vivo and in vitro pharmacology support the indication, with significant tumor inhibition in EGFR-mutant xenografts
“Overall, in vivo primary pharmacology studies, in combination with the in vitro pharmacology studies, support the proposed indication for lazertinib and demonstrated significant tumor growth inhibition in EGFR mutant cell line xenograft models, specifically for EGFR cell lines harboring the Del19 and L858R/T790M mutations.”
