tamnorzatinib (ONO-7475) / Ono Pharma - LARVOL DELTA

Anexelekto (Axl)/Mer inhibitor tamnorzatinib in patients with relapsed/refractory acute myeloid leukaemia: Results from a phase I (monotherapy) and phase II (combination with venetoclax) clinical study. (PubMed, Acta Haematol) - P1/2 | "Tamnorzatinib alone and in combination with venetoclax was safe and well tolerated but failed to induce robust clinical efficacy in R/R AML."

AXL inhibition as an immune-enabling targeted therapy for glioblastoma (SNO 2025) - "In an expanded analysis, comparison across four GSC lines treated with a panel of AXL inhibitors including BMS777607, bemcentinib, ONO-7475, and UNC2025 revealed differential effects on cell viability and proliferation. In conclusion, AXL inhibitors alter gene expression in a similar fashion to EGFR and BRAF inhibitors, differentially kill GSCs, reduce cell proliferation, and differentially alter macrophage immunophenotypes. This work suggests that the choice of AXL inhibitor is critically important when considering effects on the tumor immune milieu and on GBM growth suppression."

ONO-7475 phase I study: An open-label, uncontrolled study of ONO-7475 in combination with osimertinib in EGFR mutated advanced non-small cell lung cancer (ESMO 2025) - P1 | "In the overall population, mPFS was comparable to the previously reported result of osimertinib monotherapy. ORR and PFS for patients with Axl high expression was comparable to those with Axl low expression, hence ONO-7475 might have the potential to suppress resistance to osimertinib promoted by Axl signaling in patients with Axl high expression."

Development of an initial triple combination therapy targeting EGFR, AXL, and FGFR for EGFR-mutated non-small cell lung cancer (AACR 2025) - "Our findings demonstrate that the FGF2-FGFR1 signaling pathway contributes to adaptive resistance to the combination of osimertinib and ONO-7475 in EGFR-mutated NSCLC with high AXL expression. The triple combination therapy of osimertinib, ONO-7475, and BGJ398 showed safety and prevented tumor regrowth in CDX models, suggesting that this regimen has the potential to improve outcomes for patients with EGFR-mutated NSCLC."

Triple combination therapy comprising osimertinib, an AXL inhibitor, and an FGFR inhibitor improves the efficacy of EGFR-mutated non-small cell lung cancer. (PubMed, Cancer Lett) - "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."

Circulating small extracellular vesicles promote proliferation and migration of vascular smooth muscle cells via AXL and MerTK activation. (PubMed, Acta Pharmacol Sin) - "Pretreatment with BSM777607 (pan-TAM inhibitor), bemcentinib (AXL inhibitor) or UNC2250 (MerTK inhibitor) blocked csEV-induced proliferation and migration of VSMCs. Finally, we demonstrated that dual inhibition of AXL/MerTK by ONO-7475 (0.1 µM) effectively hindered csEV-mediated proliferation and migration of VSMCs in ex vivo mouse aorta injury model. Based on these results, we propose an essential role for csEVs in proliferation and migration of VSMCs and highlight the feasibility of dual AXL/MerTK inhibitors in the treatment of vascular diseases."

Identification of ADRN-specific, MES-specific, and pan-subtype therapeutic targets in neuroblastoma (AACR 2022) - "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."

AXL/MERTK inhibitor ONO-7475 potently synergizes with venetoclax and overcomes venetoclax resistance to kill FLT3-ITD acute myeloid leukemia. (PubMed, Haematologica) - "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."

A novel Axl and Mertk dual inhibitor ONO-7475: A new therapeutic agent for the treatment of FLT3-ITD and -wild-type acute myeloid leukemia (AML) overexpressing (AACR 2018) - P1; "Our data suggest that Mertk may play an important role in survival signaling in FLT3-WT AML. Therefore, targeting both Axl and Mertk by ONO-7475 could be a new strategy for the treatment of FLT3-WT patients with AML in addition to FLT3-ITD. Additional work to investigate and clarify for target populations in both FLT3-ITD and -WT AML is currently under way."
