体外研究 (In Vitro) | Zipalertinib (TAS6417) inhibits EGFR phosphorylation and downstream molecules in NSCLC cell lines expressing EGFR exon 20 insertions, resulting in caspase activation[1]. Zipalertinib (TAS6417) is a robust inhibitor against the most common EGFR mutations (exon 19 deletions and L858R) and the most potent against cells harboring EGFR-T790M (1st/2nd generation TKI resistance mutation)[2]. Zipalertinib (TAS6417) covalently modified the cysteine residue at position 797 of recombinant EGFR harboring an in-frame insertion mutation in the exon 20 region[1]. Zipalertinib (TAS6417) inhibits EGFR signal transduction, leading to cell growth inhibition and apoptosis induction in NSCLC cells driven by EGFR exon 20 insertion mutations[1]. Zipalertinib (TAS6417) (0-10 μM) inhibits cell proliferation and EGFR signaling in NSCLC cell lines harboring EGFR common mutations in the presence or absence of T790M[2].
Apoptosis Analysis[2] Cell Line: | PC-9, H1975, BID007, BID019, BEAS-2B cells. | Concentration: | 0-10 μM. | Incubation Time: | 24-48 h. | Result: | Led to apoptosis via inhibition of mutant EGFR. |

体内研究 (In Vivo) | Zipalertinib (TAS6417) (10-200 mg/kg) causes persistent tumor regression in vivo in EGFR exon 20 insertion-driven tumor models. TAS6417 inhibits mutant EGFR in tumors but not WT EGFR in skin tissues[1]. Zipalertinib (TAS6417) had no effect on EGFR-independent proliferation in NCI-H23 or NCI-H460 cells[1]. Zipalertinib (TAS6417) administered at 20 mg/kg, which achieves complete suppression of tumor growth, induces a significant decrease in pEGFR, leading to reduction of pAKT and pERK at 1 h. The inhibitory effect is still noted at 6 h, and phosphorylation of EGFR, ATK, and ERK recovered by 24 h[1]. Zipalertinib (TAS6417) (100 and 200 mg/kg/day) prolongs survival of animals bearing lung cancer[1].
Animal Model: | Mice implanted with NCI-H1975 EGFR D770_N771insSVD xenografts[1]. | Dosage: | 50 and 100 mg/kg. | Administration: | Orally once daily for 14 days. | Result: | Showed marked tumor growth inhibition with treatment/control (T/C) ratios of 51% and 19%, respectively. |
