Mechanism of Action

Targets/IC₅₀/Ki	Del19/T790M (Cell-free assay) 1.7 nM L858R/T790M EGFR (Cell-free assay) 2 nM Del19 (Cell-free assay) 5 nM L85R (Cell-free assay) 20.6 nM WT EGFR (Cell-free assay) 76 nM
In vitro	Lazertinib targets the activating EGFR mutations Del19 and L858R, as well as the T790M mutation, while sparing wild type. In NSCLC cell lines and primary cancer cells from patients harboring EGFR mutations, YH25448 more potently inhibits cancer cell growth and significantly increases tumor cell apoptosis compared to osimertinib. In the cell proliferation assays, GI50 values of lazertinib are 6 nM, 5 nM, and 711 nM for H1975 cells (L858R/T790M), PC9 cells (del19) and H2073 cells (wt), respectively.
In vivo	In an in vivo mouse model implanted with H1975 cells, once-daily YH25448 treatment results in indramatic dose-dependent tumor regression in both subcutaneous and intracranial lesions with no abnormal signs such as skin keratosis. The plasma half-life of YH25448 is 5.9-6.8 hr, while the tumor to plasma AUC_0-last ratio is 3.0-5.1 in tumor-bearing mice. YH25448 shows excellent penetration of the blood-brain bartier, achieving CSF concentrations exceeding the IC50 value for pEGFR inhibition. YH25448 shows superior efficacy for tumor regression in an EGFR mutant brain metastasis model.
