Cell-based assays showed that triple therapy with osimertinib, ONO-7475, and the FGFR inhibitor BGJ398 significantly increased apoptosis by increasing expression of proapoptotic factor Bim and reduced cell viability compared with that observed for the osimertinib-ONO-7475 therapy. Xenograft models showed that triple therapy considerably suppressed tumor regrowth. A novel therapeutic strategy of additional initial FGFR1 inhibition may be highly effective in suppressing the emergence of osimertinib- and ONO-7475-resistant cells.
MES neuroblastoma cell lines are more sensitive to small molecule AXL inhibitors (Cabozantinib, NPS-1034, and ONO-7475) compared to ADRN cell lines. Here we have identified and prioritized ADRN-specific, MES-specific, and pan-subtype neuroblastoma therapeutic targets and suggest AXL-targeted therapy may eliminate both MES-dominant neuroblastoma cells and immune cell populations that contribute to an immunosuppressive microenvironment.

Compared to ONO-7474 monotherapy, the combination of ONO- 7475/ABT-199 was even more potent in reducing leukemic burden and prolonging survival of mice in both model systems. These results suggest the ONO-7475/ABT-199 combination may be effective for acute myeloid leukemia therapy.
These results demonstrate that ONO-7475 suppresses the emergence and maintenance of tolerant cells to the initial EGFR-TKIs, osimertinib or dacomitinib, in AXL-overexpressing EGFR-mutated NSCLC cells, suggesting that ONO-7475 and osimertinib is a highly potent combination for initial treatment.
