Background Information:
The first-line treatments suggested for NSCLC patients with sensitising EGFR mutations are epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) gefitinib, erlotinib, and afatinib. Despite the impressive responses with first- and second-generation EGFR-TKIs utilised in treating patients with sensitising EGFR mutations, most patients still develop resistance. One of the expected resistance mechanisms to first- and second-generation EGFR-TKIs is the gatekeeper Thr790Met mutation found in an estimated 60% of resistant tumours. Nazartinib is a third-generation, new, permanent, oral EGFR-TKIs that selectively impedes EGFR-TKIs sensitising mutations, and Thr790Met resistance mutations are suggested as the first-line treatment of NSCLC patients with Thr790Met-positive. In some previous studies, nazartinib demonstrated clinical activity in patients suffering from Thr790Met-positive NSCLC. However, the present study will examine the clinical safety and efficacy of nazartinib in patients with EGFR-mutated NSCLC. [1]
Target: EGFR, H1975, H3255, HCC827
Ki: 31 nM
In Vitro: Nazartinib (EGF-816) has inhibitory effect on the mutant cell lines with IC50s of 4, 6, 2 nM in H1975, H3255, and HCC827, respectively, and demonstrates improved ADME and PK properties. [2] Nazartinib (EGF-816) shows potent inhibition of pEGFR levels in H3255, HCC827, and H1975 cell lines with EC50 values of 5, 1, and 3 nM, respectively. Nazartinib inhibits cell proliferation, with EC50 values of 9, 11, and 25 nM in H3255, HCC827, and H1975, respectively. Nazartinib has an OC50 (compound concentration at 50% occupancy) value of 2 and 5 nM on HCC827 and H1975, respectively. [3]
In Vivo: In H1975 mouse xenograft model, Nazartinib (EGF-816; 50 and 20 mg/kg or 25 mg/kg, p.o.) demonstrates dose-dependent efficacy with near complete tumor cells regression at the highest dose tested (50 mg/kg). [2] In H1975 mouse model, Nazartinib (EGF-816; 10 mg/kg, p.o.) induces tumor growth inhibition with a T/C (tumor/control volume) of 29%, and when doses are 30 and 100 mg/kg, tumor regressions are achieved (T/C, -61% and -80%, respectively). In the H3255 xenograft model, Nazartinib (30 mg/kg, p.o.) shows significant antitumor activity. Antiproliferative activity of Nazartinib on 89 lung cancer cell lines indicates that Nazartinib selectively inhibits cell lines containing EGFR with catalytic domain mutations. [3]
