生物活性

ONO-7475 is a potent, selective, and orally active Axl/Mer inhibitor with IC50 values of 0.7 nM and 1.0 nM, respectively. ONO-7475 sensitizes AXL-overexpressing EGFR-mutant NSCLC cells to the EGFR-TKIs, suppresses the emergence and maintenance of tolerant cells. ONO-7475 combines with Osimertinib provides a bright promise for the study of EGFR-mutated non-small cell lung cancer (NSCLC).

体外研究

ONO-7475 is against recombinant human AXL with IC50 values of 0.414 nM and 0.7 nM in off-chip MSA and ACD cell-based tyrosine kinase assay, respectively. It is against AXL, MER, TYRO3, TRKB, PDGFR alpha, TRKA, and FLT3 activities with IC50 values of 0.7 nM, 1.0 nM, 8.7 nM, 15.8 nM, 28.9 nM, 35.7 nM and 147 nM, respectively in a Cell-based Tyrosine Kinase assay.
ONO-7475 (0.0001 μM-1 μM; 72 hours) increases the sensitivity to Osimertinib and Dacomitinib and reduces the viability of high AXL-expressing PC-9 and HCC4011 cells, but not of low-AXL-expressing HCC827 cells. Besides, ONO-7475 enhances Osimertinib efficacy on the viability of cell lines PC-9, PC-9KGR, and HCC4011, and H1975, all of which express high levels of AXL. But it has a marginal effect on the viability of cell lines HCC827, HCC4006, and H3255 with low levels of AXL.
ONO-7475 (1 μM; 4 or 48 hours) combines with Osimertinib markedly inhibits the phosphorylation of AXL, AKT, and p70S6K compared with the treatment of the high-AXL-expressing cell lines treated with Osimertinib alone at 4 hours. It combines with osimertinib increases cleaved PARP in PC-9 and HCC4011 cells compared with the treatment with Osimertinib alone.

Cell Viability Assay

Cell Line: High AXL-expressing cell: PC-9,HCC4011,H1975, PC-9KGR cells
Low AXL-expressing cell: HCC827, HCC4006, and H3255 cells
Concentration: 0.0001 μM; 0.001 μM; 0.01 μM; 0.1 μM; 1 μM
Incubation Time: 72 hours
Result: Increased the sensitivity and efficacy to Osimertinib in AXL-high level cells.

Western Blot Analysis

Cell Line: PC-9, HCC4011 cells
Concentration: 1 μM
Incubation Time: 4 or 48 hours
Result: Increased p-AXL, AKT, and p70S6K expression at 4 hours and increases p-PARP expression at 48 hours when combindes with Osimertinib.
体内研究

ONO-7475 (oral gavage; 10 mg/kg or combines with 5 mg/kg Osimertinib; 29 days) treatment alone has little effect on the tumor growth. Besides, Osimertinib alone causes tumor regression within one week, but the tumors reappear within three weeks. The combined initial treatment causes tumor regression and the size of tumors is maintained for 4 weeks. No apparent adverse events, including weight loss are observed during these treatments.

Animal Model: Mouse CDX model using high-AXL-expressing PC-9KGR cells (exon 19 deletion and the exon21-T790M mutation in EGFR)
Dosage: 10 mg/kg; once daily; 19 days
Administration: oral gavage
Result: Had little effects alone, but combined treatments significantly decreased tumor volume without reappear.
